1.1 Product OverviewThe DART digital microwave radio

available from DMC Stratex Networksprovides last-mile, wireless transmission for

point-to-point digital radio interconnection. It

offers an extremely cost-effective, all

outdoor, single E1 or DS-1 digital

microwave connection to applications

requiring modest data capacity. The DART

also provides an ideal leased line alternative.

The all-outdoor design makes the DART

radio an ideal complement to the new

generation of microcell/picocell, all-outdoor base stations that cannot accommodate

the indoor units of traditional microwave radio systems. It also provides network

service providers and enterprise network managers with a competitive solution toleased-lines. DART radios allow connection of a customers network without the

aggravation and costs associated with the use of incumbent carrier wire-lines, or the

high costs associated with self-installation of wire or fiber connections.

The DART radio is designed for use in licensed bands for fixed wireless

transmission. To safeguard your capital investment in equipment, it protects againstinterference from other wireless systems. With todays streamlined licensing process,

a license to operate a wireless system can be obtained in less than a week in most

cases, all while the system installation is in progress. DARTs advantages over

unlicensed wireless systems include greater availability of the link, longer life, less

interference from other systems and higher transmission integrity.

2 Introduction DARTUser Manual

1.2 Configure & Monitor Dart by ComputerFor simplified installation, commissioning, and maintenance, LinkView (the DMC

Stratex Networks radio software tool for DART) is used to configure and monitor the

DART radios. This eliminates the need for hardware switches or factory installed

options.A simple commissioning procedure allows you to configure both the local and

remote radios in minutes from one end of a functioning link. Parameters that can be

set with LinkView include:

transmit and receive frequencies

transmit power level

link ID codes

receive signal level (RSL)

bit error rate (BER) alarm limits

tributary loopbacks

LinkView can also be used to configure the local SNMP (Simple NetworkManagement Protocol) interface, IP address, subnet mask, and other settings to

efficiently manage your connections.

Once your system is configured, LinkView provides the ability to monitor and

change alarms, RSL, and BER at the local and remote ends. This information is

updated in real time. Diagnostic loopback capability is also provided.

1.3 Architecture and ComponentsThe DART is a single E1 or DS-1 digital radio system designed to meet

microcell/picocell and last-mile access requirements. The DART allows transmission

of a single E1 (2.048Mbps European Standard) or DS-1 (1.544Mbps North American

Standard) data stream through a radio contained in a compact outdoor unit (ODU).The ODU attaches directly to an antenna. Two antennas and two ODUs are required

to complete a point-to-point link.

DartOutdoor Unit

(ODU)Compact design

forconvenient,unobtrusiveinstallation

269 mm (10.6 in) 83 mm (3.3 in)

A DART terminal is an ODU (outdoor unit) and an antenna connected together at the

same location. The local terminal communicates with a remote terminal via radio

signals transmitted and received by the antennas. This configuration is known as alink and is identified by a link ID. The link ID is used to prevent interference betweendifferent links operating in the same geographic area.

Embedded DART code may be downloaded to local and remote ODUs usingLinkView, or via SNMP (Simple Network Management Protocol) through the

optional NMI (Network Management Interface).

Surge Protection

The DART ODU is designed with surge protection. The cable to the ODU has either

12 or 16 wires (6 or 8 twisted-pair cable. The 8 twisted-pair cable is required if the

optional NMI (Network Management Interface) card is installed. Each of the 16wires is protected with surge arrestors at the ODU. No additional surge protection is

required for typical DC line surges.

However, for areas prone to lightning, a Lightning Arrestor (LA) is suggested for

protection of components inside a building or shelter. Please contact your local DMC

Stratex Networks representative for assistance in selecting a lightning arrestor.

detector, and a multiply-by-M (M dependent on ODU frequency) output that drives

the up- and down-conversion mixers for the transmitter and receiver. The

Intermediate Frequency (IF) drive for the transmitter is provided by the DART main

circuit board. The maximum IF drive level is nominally +7 dBm, and transmitter

output power variation is achieved by varying the IF drive level. This gives a

minimum transmitter output power range of -5 dBm to +15 dBm. The frequency of

the transmitter IF drive varies from 2-3GHz, depending on ODU frequency. The IF isFSK (Frequency Shift Key) modulated by the baseband transmit signal.

Main Board

The main board is divided into 6 major sub-sections: a power supply, a cable

interface, a microprocessor, a Field Programmable Gate Array (FPGA), a transmitter,

and a receiver.

Power Supply - Main Board

The power supply accepts +/-24 to +/-60 VDC. Power consumption of theDART radio is typically 30 watts (35 watts with NMI option). Ripple

tolerance is 200mv p-p, 50 Hz to 20 kHz. A switching power supply

module on the main board regulates the output voltages. To further reduce

power supply noise on the board, output voltages are also regulated by linear

mode regulators. Supply output voltages are +12V, +5V, and -5V. The +5V

supply is split into three separate supplies. Two of these supplies drive the

transceiver module (one for the transmitter power amplifier, one for the

VCO and other circuitry), and one drives the PCA (Printed CircuitAssembly) logic. Heat sinking for both linear and switching regulators is

provided by the massive baseplate, which is a very efficient heat dissipater.

Cable Interface - Main BoardThe cable interface consists primarily of level translators that shift TTL

(Transistor-Transistor Logic) level signals from the processor to RS422,

RS232, and E1/DS-1 levels for driving the cable. LinkView can be used to

select Port 1 (via DB-9 connection) and Port 2 (via RJ-45 connection)

functionality. Port 1 can be configured as either a LinkView interface port or

a SLIP/PPP network port. Port 2 can be configured as either a SLIP/PPP

port or a 10Base-T Ethernet port.

Microprocessor - Main Board

The microprocessor controls all the basic functions of the radio and providesa user interface to allow control and monitoring of all the vital radio

parameters. The embedded code for the microprocessor is stored in

electrically erasable memory, which allows the code to be updated in the

field without taking the unit out of service. Radio parameters are controlled

and monitored through digital input/output lines, 4 analog outputs, and 12

analog inputs. The microprocessor also communicates to the SNMP option

board and to the FPGA through dual port RAM devices. The SNMP

communication channel allows the processor to send and receive radio

8/10/2019 Dart DMC

parameters to and from a network via the SNMP option board. The FPGA

interface allows the processor to insert and extract data from the overhead

channel of the radio link. This allows the user to control and monitor both

sides of a radio link from a single location.

Digital-to-Analog (D/A) Converter - Main BoardThe output of the digital-to-analog converter (D/A) includes transmit power

control, transmitter modulation deviation, and AGC voltage output (with

respect to RSL). Transmit power control values are determined during

calibration and stored in the tombstone (a database stored in non-volatile

memory that contains the radio configuration parameters). The values,

ranging from 0 to 255 bits (corresponding to 0 to 5 Volts), are obtained at

three frequencies for each of three temperatures (cold, hot, and ambient).

AGC voltage output is proportional to received signal level. The voltage iscalibrated such that 1 VDC is equivalent to 80 dBm, with AGC voltage

increasing 0.1 V for each 1.0 dB increase in RSL up to 5 VDC (-40 dBm).

AGC (VDC) 1.0 2.0 3.0 3.5 4.0 4.5 5.0

RSL (dBm) -80 -70 -60 -55 -50 -45 -40

AGC/RSL Accuracy = 3dBm

Analog-to-Digital (A/D) Converter - Main Board

The input to the analog-to-digital converter (A/D) includes RSL calibration,

temperature sensor calibration and AGC output voltage from the D/A. RSL

calibration is a linearization of the AGC voltage for ease of use in tracking

the RSL. The values for RSL will be determined during factory calibration

at three frequencies for each of three different temperatures (cold, hot, andambient) and stored in the tombstone. The AGC output voltage from the

D/A is fed back to the A/D.

Transmitter - Main Board

NRZ (Non Return to Zero) data from the FPGA (the aggregate transmit databit stream) is fed to a variable gain amplifier. The modulation index of the

transmitted signal can be varied under microprocessor control by changing

the gain of this amplifier. The output of the amplifier drives the modulation

port of the transmit IF oscillator to generate an FSK modulated carrier at

around 2500 MHz. The carrier is phase-locked to a crystal reference for

stability. The carrier then passes through an attenuator circuit that iscontrolled by the microprocessor. The microprocessor controls the final

transmitter output power by varying the IF drive level. The carrier passes

through a final amplifier stage and a bandpass filter before going into the

transceiver IF input.

Linearizationof AGCVoltageand RSL

8/10/2019 Dart DMC

15/161



850-900203-001, Rev. D

Receiver - Main Board

The received IF (roughly 1750 MHz) from the transceiver module passes

through a bandpass filter into a 20 dB gain stage before entering the second

down-conversion mixer. The LO for the mixer is 70 MHz below the receive

IF and phase locked to a crystal reference. The resulting 70 MHz IF passes

through a SAW (surface acoustic wave) filter, which determines the overallselectivity and noise bandwidth of the receiver. The bandwidth of the SAW

filter is dependent on the data rate of the radio. The received signal goes into

an AGC (automatic gain control) amplifier with an AGC range of

approximately 60 dB. The AGC voltage is conditioned and sent to the

microprocessor for display of RSL. The IF signal then passes into a limiting

IF and quadrature demodulator circuit. The demodulated baseband signal is

amplified, converted to NRZ data, and then sent to a clock recovery circuit.

This baseband aggregate data stream is fed into the FPGA, where it is de-

scrambled, error corrected, de-multiplexed and routed out to the customer

data interface for DS-1/E1 data and to the microprocessor for overhead

processing.

Field Programmable Gate Array (FPGA)

The FPGA provides the multiplexing and de-multiplexing of overhead data

into the customer data stream, the scrambling and de-scrambling of the

aggregate data stream, the forward error correction (FEC - type: BCH)

encoding and decoding, the user port switching functions, and the logic for

various functions in the radio. The overhead data is comprised of framingand parity bits, FEC coding bits, inter-processor communication bits (so the

processors on each end of the radio link can communicate), stuffing bits to

compensate for transmit and receive clock frequency variation, and spare

bits for future expansion. The customer data runs through a first-in-first-out

(FIFO) buffer to smooth out the data transfer to and from the aggregate datastream.

1.4 Accessories

Optional ODU Cables

There are several ODU cable types available for purchase with DART radios.

The type of cable selected depends on the length of cable required, the inputvoltage, and both power consumption and power budget requirements for the

terminal. The power consumption specification of the DART radios is typically

30 watts per terminal. However, the cable will add further power dissipation,

depending upon the length and input voltage. A cable reference table is provided

for the recommended cable lengths for each voltage input and each cable

accessory (standard or custom cable) based upon a typical power budget (ODU

and cable) of 35 watts. This reference table should be used as a guide to

Optional Antennas and Remote ODU MountThe DART ODU attaches directly to an antenna (with an XP slip-fit connection) or

to a remote ODU mount. The antenna and remote mounts provide a weatherproof

connection and secure mounting (lockable) latches for the entire ODU. Typicalantenna sizes in the frequency bands for the DART are available from a variety of

antenna vendors. The antennas with the integral slip-fit connection are available for

the DART terminal from DMC Stratex Networks, and can be ordered at the same

time as the DART terminals and optional equipment. The remote mount for the

DART ODU requires an antenna with a waveguide type (versus an XP slip-fit) for

connection of a piece of flexible waveguide (1 foot to 4 feet available). The remote

mounting of the ODU is typically for inaccessible antenna installations or for

reducing the overall profile of the installation if required.

1.5 Options

Optional Cable Termination Unit (CTU)

Optional CTUs are available for use with DART radios. The CTUs are designed toprovide specific interfaces. The CTUs provide a standard interface for

transmit/receive data, power, alarm summary, and management connections. They

act as a convenient method of terminating the DART ODU cable. These signals are

combined in a multi-pin cable connected to the DART radio. The CTUs also convert

the RS422 communications link from the ODU to RS232 for use with a standard

laptop. Two versions of cable termination units are available: Deluxe and Standard.

The Deluxe CTU is available as balanced (DS-1, E1) and unbalanced (E1). The

Standard CTU is available as balanced (DS-1, E1), E1CSU/DSU (V.35), unbalanced

(E1) or as Ethernet (10 Base-T). The Deluxe CTU was specifically designed for

customer applications requiring the ability to confirm customer traffic withoutinterruption (generally during trouble calls). The Standard CTU was designed to

standardize the unit across customer applications and minimize the size of the unit toallow for compact rack mounting (2 standard CTUs can be mounted in one 19-inch

rack unit).

Optional Network Management Interface (NMI)

The Network Management Interface (NMI), an optional Simple NetworkManagement Protocol (SNMP) interface card, is offered for the DART. The optional

NMI card is fully SNMP compliant and offers a standards-based open-system

network management solution allowing integration with an SNMP compliant

Network Management System (NMS). The optional NMI card is ordered from the

factory at the same time as the DART terminal, and is inserted in the ODU and tested

during production. The NMI card connections can be accessed through the ODU

cable or through one of the optional CTU/CTS termination devices.

The optional NMI card implements IP (Internet Protocol) technology for addressing

and routing to and from the configured ports. A network can be configured as a

private Intranet, or it can be connected directly to the Internet. Password protection

keeps the system secure in either configuration. The open system concept of SNMP

allows the optional NMI card to be accessed with any SNMP MIB Browser

application.

The figures below show how typical NMI cards are set up for ODUs in a network

node interface and in a daisy chain configuration. Notice that not all DART ODUs

require optional NMI cards for network connectivity. If throughput of the SNMP

communications is not required (as would be required in daisy chain configurations),

the local ODU is capable of managing the remote ODU in a link.

Refer to Chapter 9, DART ProductOrdering Guide, for ordering information on

hardware and software installation kits.

The DART ODU includes a Mil-style female connector for terminating the ODU

cable (ordered separately) for connection to the ODU. Similarly, the Deluxe CTU

(DS-1/E1) and the CTS include a Mil-style male connector for terminating the

ODU cable at the indoor end. The Standard CTU does not require a Mil-style

connector, as the ODU cable terminates directly to a terminal strip inside the unit.

Prepare for installationThe DART ODU (outdoor unit) may be used with an antenna that has the DMC

Stratex Networks customized (XP-type slip-fit) interface, or with a typical waveguide

type antenna interface. The ODU uses catches and spring-loaded retention clips on

the antenna interface to attach directly to an XP type slip-fit antenna. A remote ODU

mount option is available for standard waveguide connection to a standard waveguideantenna interface.

See Chapter 6 for instructions on configuring DART.

NOTE:

If a CTU (Cable Termination Unit) or a CTS (Cable Termination Strip) willserve as the connection point for the computer running LinkView, install that

equipment first. See Install DART Accessories & Options, page 22,forinstallation instructions.

Mount ODU to Antenna

Step 1. Install the antenna according to the antenna manufacturers instructionsincluded with the antenna.

Step 2. Choose between integral or remote mounting of the ODU to theantenna. Mount the ODU. The procedure for completing this step is

different, depending on whether you choose integral (slip-fit) or remotemounting.

Integral Mounting (XP-Type Slip-Fit Antenna Interface)

A. Attach the ODU to the antenna using the captive spring clips on

the antenna. The arrow on the label attached to the ODUs

baseplate indicates polarization.

B. A padlock can be used to ensure that the terminal is secured to

the antenna.

Remote Mounting (Waveguide Type Antenna Interface)

Antenna/ODU Remote

Mount

O D U

Certain installations of the DART terminal require the ODU to be mounted

away from the antenna instead of using the integral XP type slip-fit. The

following instructions are for remote mounting of the DART ODU away

from a waveguide type antenna.

A. Order the optional remote mount kit (frequency band dependent)from DMC Stratex Networks and a suitable length of flexible

waveguide to connect the remote mount and ODU to a standard

waveguide type antenna with standard waveguide flanges. The

flexible waveguide is available in lengths from 1 to 4 feet (in

one-foot increments) for all DART frequency bands. Flexiblewaveguide with choke flanges, or other suitable flange with a

watertight seal, must be used to ensure the weatherproof integrity

of a DART remote mount installation.

B. Install the antenna per the manufacturers instructions included

with the antenna kit. Roughly align the antenna on the desiredpath.

C. Use the included hardware and instructions to install the remote

mount to the same or adjacent pole as the antenna. Mount the

remote mount within a distance that allows the flexible

waveguide to be installed and still have sufficient slack for

proper operation.

D. Install the flexible waveguide between the remote mount and the

antenna. Make sure to align the waveguide flanges so that the

rectangle aligns with the remote mount waveguide openings and

the antenna. Ensure that the flange gaskets are properly seated for

weatherproof operation. If an XP type slip-fit antenna is used witha remote mount installation, an optional waveguide adapter must

be ordered from DMC Stratex Networks to change the antenna

feed from an XP type slip-fit connection to a waveguide flange

(frequency band dependent). See Chapter 9, DART Product

Ordering Guide, for details.

NOTE:The remote mount canalso be wall-mountedwith locally procuredfasteners, such as lagbolts. The length andtype of fastener aredependent on the walltype.

NOTE:

E. Use the latching mechanism provided to attach the ODU to theremote mount. The arrow on the label attached to the ODUs

baseplate indicates polarization.

Step 3. Adjust the ODU/antenna assembly to the desired location on the pole

and place the antenna and ODU in approximate desired azimuth(horizontal angle) and elevation for coarse alignment of the path.

Connect the ODU cable

The ODU cable ordered separately from DMC Stratex Networks comes in a variety

of options, including cables pre-terminated with a Mil-type connector at one or both

ends.

See Chapter 9, DART Product Ordering Guideto order cables, connectors, or

custom termination devices, such as the Deluxe or Standard CTU.

Step 1. Measure the ODU cable to length. First measure approximate distancebetween the ODU mount and the terminal block, punch block or

optional DMC Stratex termination device that the other end of the cable

connects to. Then allow (add) these extra lengths:

12 to 16 inches (30.48 to 40.64 cm) for a drip-loop at the ODU.

at least 4 extra inches (10.16cm) per end for termination of the cable.

slightly more extra cable if this is your first time terminating a cable justin case a mistake is made.

See below for recommended maximum cable lengths.

Step 2. Terminate the ODU end of the cable with a Mil-style femaleconnector. To do this, follow the instructions in,Cable Assembly

Procedure - Detailed Instructions, page 34.Do NOT hook the cable

into the ODU at this point.

Step 2A. If you are installing a Deluxe CTU or a CTS, terminate the other(indoor) end of the ODU cable with a Mil-style male connector. See

Cable Assembly Procedure - Detailed Instructions,page 34 for

instructions.

Step 3. Connect the indoor end of the ODU cable to a terminal block, punchblock or one of the following three custom termination devices from

DMC Stratex Networks.

Deluxe CTU(Cable Termination Unit), page 23.

Standard CTU, page 26.

CTS(Cable Termination Strip), 32.

If youre hooking to a DMC device, turn to one of the pages listed above forinstallation instructions.

Step 4. Connect the terminal block, punch block or optional DMC StratexNetworks termination device to a DC Power Converter.

NOTE: For normal operation, the ODU requires an input power range of +/-24 to +/- 60 VDC.

Step 5. Attach the end of the ODU cable terminated with the Mil-style femaleconnector to the ODU.

Step 6. Power up the DART by switching on the DC power converter. Sinceyoull be testing for proper alignment by measuring approximate RSL

(Receive Signal Level), make sure the DART at the other end of the linkis also powered up. It is recommended that you have an assistant

stationed at the other end of the link to help with alignment.

Align the antenna

Step 1. Ensure that the DART transmitter is un-muted. This is the factorydefault, but you can verify through LinkView. See Change theTransmit Power, page 78,for information about turning on the Tx

output power for alignment operations after setting the desiredfrequency (channel).

NOTE:

Skip this step ifyour ODU cableis already pre-terminated at thisend with the

correct "Mil-style"connector.

Step 3. As you adjust the antenna, use the multimeter readings to achieveaccurate alignment. The AGC voltage corresponds to the RSL, where

the voltage steps 0.1 VDC are equivalent to 1.0 dBm steps. See the

following chart for linearization of AGC voltage and RSL (+/- 3dB

accuracy).

RSL (dBm) -80 -70 -60 -55 -50 -45 -40

AGC/RSL Accuracy = 3dBm

For maximum efficiency, it may be helpful to be in communication with a

partner stationed at the antenna on the other end of the link.

Replace the cap on the AC BNC connector when you are finished.

NOTE: While the AGC (BNC) connector is in use (cap removed), LinkViewcan only be used via the ODU (BNO) connection. When the BNC connectoris not in use (cap replaced), LinkView can be used via the ODU (BNO)

connection or via the optional CTU/CTS (RS232) connection. (The CTSrequires an RS422 to RS232 converter).

Step 4. Confirm that the AGC reading approximates the expected RSL from thepath calculations.

Step 5. Ensure that the ODU/antenna assembly is secure to the mount and thatall adjustments are properly secured.

Step 6. Secure the multi-pair cable with tie straps. Connect ground betweenODU (either metric or Imperial) and a nearby local ground point using

minimum 9AWG wire (25mm2conductor). Use an ohmmeter to confirm

proper ground.

without nicking or cutting the wire-braided shield underneath.

Step 3. Insert the cable into the cable penetration in the front panel of the CTUby first removing the strain relief strap screws and the strap itself on the

backside of the CTU front panel. Then, slide the cable through the hole

provided in the Standard CTU faceplate. Slide the cable far enough

through the penetration to ensure that the end of the cable, including the

wire-braided shield and drain wires, are completely inside the CTU. (A

piece of tape over the braided shield at the cable end may speed

insertion into the CTU).

Step 4. Trim the wire-braided shield to 1-inch (2.5 cm) beyond the outer

insulation and pull it back against the outer insulation.

Step 5. Take the six (6) or eight (8) conductors (depending upon ODU cabletype used) and remove the foil from each pair, taking care not to untwist

the pairs and confuse the wires. It is recommended that a piece of

electrical tape be used to retain the pairs. Separate the drain wires

(exposed ground wires associated with each pair) from the twisted pairs

and pull back against the wire-braided shield. Cut the twisted drain

wires to 1 inch (2.5 cm), the same length as the wire-braided shield.

Step 6. Use a twisting motion to slip the wire mesh sleeve over the conductorsdown to the wire-braided shield and drain wires. Carefully continue to

slip the wire mesh sleeve over the wire-braided shield and drain wires to

the edge of the outer insulation. Be sure not to slip the sleeve more than

1 inch (2.5 cm), or beyond the pulled back shield and drain wires.

See illustration on next page.

NOTE:

Be sure todiscardall cut wiresand braids toensure none goinside the CTU.

Step 7. Pull the cable back through the CTU hole so that the wire mesh sleeve isup against the nylon insulation bushing and on top of the cable strainrelief mount. Secure the strain relief to its mount and tighten screws to

ensure that any tugging on the cable will not allow it to be pulled loose

of the strain relief of the CTU.

Step 8. Route wire pairs to the proper location on the terminal strip on the CTUPCBA (J8 to J11, Pins 1 to 4). If the wire pairs were allowed to be

separated, it is recommended that you use an Ohmmeter to confirm each

conductors path/location before terminating the wire. Taking care to

leave enough slack in the wires for securing the pairs to the PCBA with

the tie straps, cut each conductor to length. Strip each conductor .25

inches (.75 cm). It is recommended that you tin each exposed conductor

to protect against the wires unraveling.

Step 9. After properly terminating the six (6) or eight (8) pairs of wires per thewire chart, separate the pairs into equal bundles and secure to the CTU

PCBA using the supplied tie straps and the three (3) pre-drilled holes in

the PCBA. Remove any excess from the tie straps and discard.

Step 10 Ensure that no loose wires or cut ends are touching the PCBA. It isrecommended that the board be blown with air to free all wire ends.

Step 11. Replace the CTU PCBA and attached ODU Cable into the CTU coverassembly. Take care to ensure that the PCBA is sliding between the

slots in the cover assembly sides for proper mechanical fit. Secure the

four (4) captive screws on the front panel to properly close the CTU.

Step 12. Secure the CTU to a rack (singe or double rack mountingconfiguration), to a wall using the movable mounting ears (use proper

fasteners such as concrete/drywall fasteners, or wood screws), or mount

on a desktop. Provide proper grounding to the ground lug on the front

panel for correct operation.

CTS (Cable Termination Strip)

When the features of the Deluxe or Standard CTUs are not required or when size

is a challenge, the CTS provides a compact solution for termination of the ODUcable. The CTS is a simple cable termination strip enclosed in a compact metallic

enclosure that fits in the palm of your hand. This small size allows it to bemounted virtually anywhere. The CTS provides the same general user

connections as a CTU, but in a more compact manner. All management ports are

available, as well as both balanced and unbalanced tributary connections on thesame model. However, Port 1 is only available as an RS422 connection. An

optional RS232 to RS422 cable must be ordered if a PC is to be connected to Port

1 for LinkView operations through the CTS.

Step 2. Attach the end of the ODU cable terminated with the Mil-style maleconnector to the CTS and properly mount and ground the CTS.

Step 3. Configure CTS Port 2 for the desired operation (if SNMP is used) andthe E1 balanced/unbalanced jumpers (E1 only, DS-1 is always

balanced). The shunts (jumpers) are accessible through the rear panel of

the CTS.

The Data and Port 2 conf igurat ion jumpers are located at therear of the CTS, accessible via the metal acce ss panel .

2.3 Cable Assembly Procedure - DetailedInstructionsIf the DART radio youre installing is equipped with the NMI (SNMP) moduleoption, a cable with 8 twisted-pairs (Belden 8168 or equivalent) is required.

However, if the ODU is not equipped with the NMI module option, only 6 shielded

twisted-pairs (Belden 8166 or equivalent) are required.

Unless the ODU cable youre working with came pre-terminated, the following

customer-supplied tools are required for assembly:

Connector termination tools

Crimp tool (for both 16 and 24 AWG)

Contact insertion tools (24 and 16 WAG tool, for both Standard and Custom cable

termination)

Contact removal tools (24 and 16 WAG tool, for both Standard and Custom cabletermination)

A Mil-style female connector for terminating the cable at the ODU end is shipped

with each DART ODU.

A Mil-style male connector for terminating the cable at the indoor end is shipped

with each Deluxe CTU (cable termination unit) or CTS (Cable Termination Strip)

available as an option from DMC Stratex Networks.

Except for flip-flopped pin locations, the procedure is identical for terminating the

cable with either connector. Step 6 of this section contains pinout diagrams for eachconnector.

NOTE: You do not need a connector on the indoor end of the ODU cable ifyoure hooking to the Standard CTU (Cable Termination Unit) also availableas an option from DMC Stratex Networks. Instead, the ODU cableconductors are terminated directly to a terminal block on the Standard CTUcircuit board. For details, see Standard CTU Installation, page 26.

See below for step by step instructions on terminating the ODU cable with Mil-

style connectors.

Step 1. The Female Connector Kit that ships with each DART ODU and theMale Connector Kit that ships with each Deluxe CTU or CTS contain

the items listed below.

Step 2. Temporarily remove the O-ring from inside the backshell. Remove anddiscard the serrated ring behind it. Replace the rubber o-ring.

Step 3 Measure the cable to length. Allow an additional 12 to 16 inches (30.48to 40.64 cm) for a drip-loop at the ODU. Allow at least 4 extra inches

(10.16cm) per end for termination of the cable. Allow slightly more

extra cable if this is your first time terminating a cable just in case a

mistake is made. Using the backshell as a guide, strip the cable outer

sheath approximately 1.83" or 46.81mm. Avoid damaging the braided

wire shield.

Step 4. Fold back the braided shell from the cable. Slide the heat shrink tubingover the cable end. Slide the backshell over the cable end, making it

even with the end of the braided shield. Do not allow the backshell to

slip beyond the braided shield. Temporarily secure the backshell in

position with tape.

Step 5. Trim back the foil from the conductor pairs. Do not remove the drainwires. If the SNMP option is not installed and the six-pair cable is used,there will be fewer wires in the cable to terminate into the 18-pin

connector (12 wires versus 18 wires).

Strip back the conductor insulation on each wire approximately .200" or

5.15mm (See the following detail drawing). Set crimping tool to setting 22

and crimp large terminals on red/black pair. Set crimping tool to setting 24

and crimp small terminals on remaining wire pairs. Divide drain wires into

two groups and crimp with two small terminals.

Step 6. Install the coupler nut over the connector insert. Make sure the couplernut is oriented correctly. Stuff the connector terminals into the

connector. Insert with the insertion tool working by rows across the

connector.

Refer to the drawing on the next page for specific pinout for the female

connector on the ODU end. Pinout instructions for the male connector on

the indoor end follow immediately after.

Step 7. After confirming that the pinout is correct, remove the tape, thread thebackshell into the connector, insert and tighten. Fold the braided shield

over the end of the backshell. Secure the braid to the backshell with a tie

strap. Trim any excess tie strap and braided shield. Position the heat

shrink halfway over the backshell. Heat the heat shrink with a suitable

heat gun. Be careful not to overheat the connector. Vapor wrap or

electrical tape can be wrapped around the connector and heat shrink tube

to add an additional vapor barrier over the heat shrink.

Step 8. Verify continuity by measuring end-to-end resistance on each pin andwire with an ohmmeter.

Warning:

Do not use the Ohmmeter to check cable continuity if one end of the cable isalready hooked to either the ODU, a CTU, or any other customer equipment.Damage to sensitive circuitry may be caused from the voltage/current presented

by the Ohmmeter.

If a short or open circuit occurs during testing, check the wire connection

and repeat measurement. Residual resistance from the cable should be seen

on nominal cable lengths.
