Entering the Startup Mode After batteries have been installed, power on the CD47C Time-Based Benchmarker by depressing the ON/OFF
power button which is located on the right side of the unit. If installed, unscrew the stainless steel switch cap to gain
access to the recessed power button. Once power is applied, the CD47C enters the STARTUP mode and displays
the CDI logo on the Backlit LCD and cycles the audible alarm along with the 16 high intensity LEDs, ON then OFF
twice. If removed, replace the power button switch cap to prevent accidental power disruptions of the CD47C while
it is in the field. Refer to Figure 5, Startup Screens.
Figure 5, Startup Screens
Before the CD47C proceeds to Startup Screen 2, it quickly retrieves its last configuration setting from non-volatile
flash memory. This configuration can be a combination of user and/or default values that are set through the Menu
System (refer to Accessing the Menus). Once the configuration has been read from memory, the CD47C initializes
and configures either the Bluetooth radio or the RS232 interface for file transfers. File transfers from the CD47C to
a computer running Marker software can be initiated only when the unit is in STARTUP and SUSPEND modes
(refer to Downloading Data). After the file transfer interface has been configured, the CD47C flashes the 16 LEDs
once and then sequences through Startup Screens 2 - 4. The screens are updated every three seconds and the
sequence will continue until the unit is placed into the Menu System or the RECORD mode. As an additional visual
aide to the user, a Startup LED, top left, will flash every time a STARTUP screen is advanced.
Startup Screen 3 and 4 provide the user with both unit configuration and status information. This information
should be verified by the operator prior to placing the unit in the RECORD mode.

Figure 5, Startup Screens 2, instructions the operator to press the RECORD buttons simultaneously to place the unit
in the RECORD mode. Passages and Ignored events are detected and saved only when the unit is in the RECORD
mode.
Startup Screen 3
Figure 5, Startup Screens 3, displays the Signal to Noise ratio that the unit requires in order to record a pig passage.
The default value is 0.5:1, but is configurable through the Menu System. Also displayed is the battery voltage,
which is constantly measured and updated with the current value. It is recommended that new D-cell batteries be
installed prior to deploying the CD47C in the field. New batteries will typically indicate a voltage of 3 volts or
greater. Memory usage is the last value displayed. Erased, memory indicates 0.17% utilization due to the stored
configuration settings occupying memory space. Additional passages can be appended to previously recorded data,
however it is recommended that memory be erased prior to deploying the CD47C on a new run.
Startup Screen 4
Figure 5, Startup Screens 4, displays the firmware version that the unit is running under. Please contact CDI to
obtain the latest firmware version.
User Configuration Settings before entering the Record Mode
Before entering the CD47C‟s RECORD mode for the first time after power-ON, the unit‟s user configuration values
should be set through the Menu System (refer to Accessing the Menus for detailed discussion). Typical
configuration values that are adjusted for include: ACQUIRE POST GPS, LOCAL TIME ZONE, RECORD MODE,
and RESET FILE MEMORY.
Entering the Record Mode Passages and Ignored events are detected and saved to non-volatile memory only when the CD47C is in the
RECORD mode. The RECORD mode can be accessed by simultaneously pressing the RECORD buttons from
either the STARTUP screens or the SUSPEND mode. Every time that the unit enters the RECORD mode it will
compensate for environmental noise by setting new threshold levels for the Magnetic and/or Transmitter Channels.
If the unit enters the RECORD mode from the STARTUP screens it will also need to acquire an initial GPS time and
position before data can be recorded.
Determining Magnetic Environment
To minimize false triggers on the Magnetic and Transmitter Channels, the CD47C compensates for the
environmental noise at its current location by automatically adjusting the threshold levels of both channels. The
goal of this routine is to compensate for environmental noise, but maintain sensitivity so that actual pig passages can
be detected. If the CD47C is unable to accomplish this goal a warning message is displayed on the LCD, refer to
Figure 8 Compensating for Magnetic Environment fails.
Figure 6 Increasing the Threshold Overcomes Magnetic Noise
Background Magnetic Interference (Noise)
Operating Sensitivity Level (Threshold)
Initial Sensitivity Level (Threshold)
CD47C Time-Based Benchmarker Operation Manual 89-09-0023-00 Rev. A
Page 7 of 20
The task of compensating for the environment noise begins by setting the thresholds to initial values, magnetic
threshold = 0 and transmitter threshold = 10. Then a timer with an initial setting of 45 seconds begins to count
down. During the countdown, if a channel detects a false trigger, its threshold is increased by 2 and the timer is
reset back to 45 seconds. The routine has successfully completed when the thresholds have been adjusted to
minimize environmental noise and the timer has counted down to zero, refer to Figure 7, Determining Magnetic
Environment.
Figure 7, Determining Magnetic Environment
To help speed up the routine and make it more efficient, the CD47C will only monitor the active channels as set in
the Menu System (refer to Accessing the Menus). If the RECORD mode is set for both magnetic and transmitter
detection, then both channels will have their thresholds compensated for. Otherwise, only the active channel,
magnetic only or transmitter only will have its threshold adjusted for when compensating for environmental noise.
If time warrants, the process can be bypassed by simultaneously pressing the RECORD buttons. If this is the first
time that the compensation routine has run, bypassing will set the thresholds to magnetic = 10 and transmitter = 30,
otherwise the thresholds are set to the values obtained from the previous time that the routine was able to run to
completion.
Figure 8, Compensating for Magnetic Environment fails
If the Magnetic Environment routine fails, either the CD47C needs to move to a quieter location and restarted or the
excessive noise source needs to be eliminated.
Acquiring Initial GPS Time and Position
GPS information is used in all of the CD47C‟s time calculations for pig passages, and is a necessary step for the
CD47C to function properly in the field. If the CD47C enters the RECORD mode from the STARTUP screens it
will need to acquire an initial GPS time and position before data can be recorded. Once the Magnetic Environment
test is complete, the CD47C will immediately begin to acquire an initial GPS time and position, refer to Figure 9,
Acquiring Initial GPS Time and Position.
The CD47C will first attempt to acquire an accurate GPS time and then an accurate GPS position. The CD47C‟s
internal GPS module needs to receive the signals from at least 4 orbiting GPS satellites to acquire valid GPS time
and position. If the module receives less than 4, the Satellite Signal is Unacceptable message will be displayed on
the LCD. If the module receives the signal from 4 or more satellites, the Satellite Signal is Acceptable message will
be displayed on the LCD. The LCD display and button side of the CD47C needs to have clear access to an open sky
for its internal GPS module to perform properly and receive enough satellite signals to acquire GPS time and
position.
Press RECORD simultaneously to load default threshold values
CD47C Time-Based Benchmarker Operation Manual 89-09-0023-00 Rev. A
Page 8 of 20
Figure 9, Acquiring Initial GPS Time and Position
While acquiring GPS time and position, if communications with the internal GPS module is valid, a series of
sequencing asterisks will be displayed on the LCD. The series is a constantly repeating pattern of 0 to 3 asterisks,
incrementing every 1 to 3 seconds. If the series fails to increment, internal communication problems with the GPS
module are occurring. If problems arise, the CD47C should first be powered OFF, battery voltages checked and if
necessary, the batteries replaced. Next, power the unit back ON and reenter the RECORD mode by pressing the
RECORD buttons simultaneously. If internal GPS communication problems still persists the unit will need to be
taken out of service and repaired.
After approximately 20 minutes, if the CD47C is unable to obtain valid GPS information due to problems with
either the communication to its GPS module or the module is unable to acquire enough satellites needed for
obtaining accurate GPS time and position, a warning message will be displayed, refer to Figure 10, Warning
Message if Acquiring GPS Fails.
Figure 10, Warning Message if Acquiring GPS Fails
Detecting Pig Passages
Once environmental noise has been compensated for by adjusting threshold levels and an initial GPS time and
position has been obtained, the CD47C is in the RECORD mode. The CD47C‟s Magnetic and/or Transmitter
Channels are now active and any Passages or Ignored events that are detected are saved to non-volatile Flash
memory.
When the CD47C is in the RECORD mode, the LCD display will sequence through two screens every five seconds.
The screens inform the user of the last acquired GPS position and that the unit is actively waiting to detect pig
passages, refer to Figure 11, Detecting Pig Passages. Both screens contain information regarding the unit‟s startup
time, the current time, and if present, the time that the last pig passage was detected and stored into memory. As an
additional visual aide to the user, a RECORD mode LED, bottom right, will flash every time a screen is advanced.

Figure 11, Detecting Pig Passages
Analyzing Events Screen
When in the RECORD mode, the CD47C will only detect the signal of the active channel(s). The active channel(s)
can be set in the Menu System (refer to Accessing the Menus) to be MAGNETIC only, TRANSMITTER only, or
BOTH. When the duration of the detected signals from the active channel is long enough, as when a pig passage
occurs, the CD47C begins to save the received data to its non-volatile memory. As the data is being saved the LCD
backlight comes on and the LCD informs the user that the CD47C is analyzing a magnetic disturbance, refer to
Figure 12, Analyzing Magnetic Disturbances.
If the total duration of the detected signal is long enough and its signal to noise ratio is acceptable, the CD47C posts
the disturbance as a valid pig passage. Once the pig has passed and is out of range of being detected by the
CD47C‟s active channel, the CD47C closes the saved passage record by storing additional information that is used
by CDI‟s Marker software. This additional record information is necessary and valuable when analyzing the
CD47C‟s data. The information includes: Time, Position, Battery Voltage, Temperature, Number of previously
stored Ignored Events, Threshold Values, Firmware Version, Serial Number, S/N ratio, GPS Version, etc.
Ignored Events Screen
When in the RECORD mode, if the duration of the signal is too BRIEF, the magnetic disturbance is considered not
to be an actual pig passage, but instead possible noise and the data is saved in non-volatile memory as an Ignored
Event. If the duration of the detected signal is long enough but exceeds the limits of the signal to noise ratio, the
magnetic disturbance is considered too NOISY and the data is saved as an Ignored Event, refer to Figure 13, Ignored
Events. Typically, environmental noise is cancelled out when the active channel(s) thresholds are set prior to
entering the RECORD mode. However, while waiting for a pig passage to occur, environmental conditions and
sources of noise can change, resulting in false triggering of the active channel(s).

OR
Figure 13, Ignored Events
The information saved from a resulting Ignored Event includes: the Time that the event was detected, Date, too
Brief or too Noisy, Battery Voltage, Temperature, Peak Signal Level, etc. The Ignored Event record information is
necessary and valuable when analyzing the CD47C‟s data in CDI‟s Marker software. Only when the data is
analyzed can the event be truly classified as an Ignored Event.
Post GPS Screen
When in the RECORD mode and Post GPS is enabled in the Menu System (refer to Accessing the Menus), the
CD47C will attempt to acquire new GPS information after a valid pig passage has been detected, refer to Figure 14,
Acquiring a Post GPS. Although obtaining a Post GPS after every passage is not absolutely necessary, under certain
circumstances it can enhance the time calculations during data analysis. There is a minute amount of drift to the
CD47C‟s internal clock, which can accumulate between long intervals of GPS acquisitions. Every time that the
CD47C acquires new GPS information, it resets its internal clock, thus minimizing any possible drift.
Figure 14, Acquiring a Post GPS
When the CD47C is configured to acquire a Post GPS, the routine can be bypassed at the operator‟s discretion by
simultaneously pressing the BYPASS buttons. Bypassing the routine can be helpful if time is of the essence and the
unit needs to be placed in the SUSPEND mode and moved to a new location. When the routine is bypassed, the
CD47C performs as if Post GPS was not enabled and no passage data is lost.
Entering the Suspend Mode The CD47C can safely be moved to another location when in the SUSPEND mode. Although still present, detected
signals from the active channel(s) are ignored, preventing any additional data being stored to memory, refer to
Figure 15, Suspend Mode. The SUSPEND mode can even be accessed while the CD47C is analyzing a magnetic
disturbance, refer to Figure 12, Analyzing Magnetic Disturbances. This can be helpful, if the operator inadvertently
creates a false disturbance while trying to place the unit into the SUSPEND mode or if the unit is accidently moved
before being placed in suspend. To enter the SUSPEND mode, press the PAUSE buttons simultaneously.

Figure 15, Suspend Mode
When the CD47C is in the SUSPEND mode, the LCD display will sequence through a series of two screens every
five seconds. The first screen informs the user that passage detections are suspended and the CD47C can be moved
without generating false triggers. The second screen instructs the user to press the RECORD buttons simultaneously
to resume recording pig passages. Both SUSPEND mode screens contain, if present, the time and date of the last
pig passage that was detected by the unit. As an additional visual aide to the user, a SUSPEND mode LED, bottom
right, will toggle on and off every time a screen is advanced.
Downloading CD47C data while in the Suspend Mode
The CD47C will allow for data downloads to CDI‟s Marker software only when the unit is in either the STARTUP
mode or the SUSPEND mode. When the CD47C is in the RECORD mode, its sole task is to detect pig passages.
The CD47C can be configured to download data from its non-volatile memory using either a serial download cable
or its internal Bluetooth transmitter (refer to Downloading Data). The user can select the method of downloading
data in the Menu System (refer to Accessing the Menus).
Synchronizing to GPS time while in the Suspend Mode
The CD47C is capable of synchronizing external devices such as, pc‟s, laptops, tools, etc. to its acquired GPS time.
The CD47C will automatically perform this operation via a serial download cable, only if the acquired GPS time is
less than one hour old. This one hour restriction ensures the accuracy of the GPS time. A newer GPS time can be
acquired by either restarting the unit and acquiring a new initial GPS time or by selecting GET GPS NOW in the
Menu System (refer to Accessing the Menus).
The cable used for synchronization is the same cable that is used for data downloads. The serial download cable has
a four pin circular connector on one end and a standard DB9 serial connector on the other. The circular connector
mates to a bulkhead connector on the side of the CD47C and the DB9 to the device that is to be synchronized. The
serial cable uses a standard RS232 configuration for TX, RX, and Ground, plus an additional Pulse per Second
(PPS) signal from the GPS module on pin 9 of the DB9. The serial interface is configured for 9600, 8, E, 1 and the
protocol used to request and receive the GPS time and date packets is described in the CDI document “Requesting
the GPS time from a CD47”, which is available upon request.
Accessing the Menus The Menu System allows the operator to customize the CD47C‟s default settings, initiate special functions, or
perform basic housekeeping routines. The unit‟s operating configuration can be a combination of user and default
settings that are set through the Menu System. The configuration settings whether user defined or default are saved
into the CD47C‟s nonvolatile Flash memory and are retained when the unit is powered off. The Menu System
consists of three top level LCD screens that can be navigated through by using the Button Bar assigned UP/DOWN
pushbuttons, refer to Figure 16, Top Level Menu Screens. As the operator moves UP/DOWN through the Menu

System, a reverse field cursor indicates the active menu item on the Menu screen. Pressing the ENTER button for
the active menu item selects that item and the CD47C drops into its associated Submenu Screen, thus allowing the
operator to change its value.
When no buttons are pressed for 20 seconds, the CD47C will exit out of the Menu System due to inactivity and
return to the operating mode it was in prior to entering the Menus. The operator can also exit from either the top
level Menus or Submenus at any time by pressing the ESCAPE button. No changes are made to the Submenu item
if the operator presses ESCAPE before the ENTER button is pressed.
Figure 16, Top Level Menu Screens
Submenu Screens
There is a Submenu Screen for every menu item of the three top level Menu Screens. It is at the Submenu level that
the menu item‟s value is changed.
Acquiring Post GPS
Figure 17, Acquiring Post GPS
In Figure 17, Acquiring Post GPS, the UP/DOWN arrow pushbuttons are used to toggle between NO/YES and
pressing ENTER selects and saves the setting. Selecting „YES‟, the CD47C will attempt to acquire new GPS
information after a valid pig passage has been detected. Once the new GPS information has been acquired, the
CD47C‟s internal clock is reset, it‟s time slaved to the new GPS time, and the new GPS information is saved into
nonvolatile memory. Although the CD47C‟s internal clock is highly accurate, acquiring new GPS information can
enhance the time calculations during data analysis. The default Post GPS setting is YES.

Setting the Local Time Zone
Figure 18, Setting the Local Time Zone
In Figure 18, Setting the Local Time Zone, the UP/DOWN arrow pushbuttons are used to increase/decrease the Time
Zone setting and pressing ENTER selects and saves the setting. Setting the Time Zone only affects the local time
that is displayed on the LCD module. It is solely for the operator‟s convenience and does not affect the times stored
by the unit for pig passages. CDI‟s Marker software, used for CD47C data analysis, uses the GMT times that the
CD47C records in its nonvolatile memory. Setting the Time Zone to zero will display the pure GMT time. The
default Time Zone setting is -6, the Time Zone for CDI in Tulsa, Oklahoma.
Setting Threshold Levels
Figure 19, Setting Threshold Levels
In Figure 19, Setting Threshold Levels, the UP/DOWN arrow pushbuttons are used to increase/decrease the
threshold level for the Magnetic and/or Transmitter Channels. Refer to Determining Magnetic Environment for an
understanding of and reason for the need to set the threshold levels. Although the procedure is performed
automatically by the CD47C prior to recoding data, the operator has the ability to bypass the routine and load either
fixed bypass values, or previously determined values, or the values that have been set in the Menu System. The
Menu System will allow the operator to first set the Magnetic threshold value and secondly to set the Transmitter
threshold value. Pressing ENTER will select and save the new setting, pressing ESCAPE will retain the previous
setting. The fixed Bypass Threshold settings are MAGNETIC: 10 and TRANSMITTER: 30.
Setting the Signal to Noise Ratio
In Figure 20, Setting the Signal to Noise Ratio, the UP/DOWN arrow pushbuttons are used to increase/decrease the
Signal to Noise Ratio. The Signal to Noise Ratio is one of the parameters used to validate a magnetic event as being
a pig passage. Increasing the ratio puts a tighter restriction on validating a magnetic event as being a pig passage.
Decreasing the ratio loosens the restriction, making it easier to classify a magnetic event as being a pig passage. The
operator needs to be careful not to set the ratio too high (true passages will be posted as IGNORED EVENTS) or too
low (Noise will be posted as PIG PASSAGES). The default Signal to Noise setting is 0.5 : 1.0.

Setting Delay ON when coming out of Suspend
Figure 21, Delay ON when coming out of Suspend
In Figure 21, Delay ON when coming out of Suspend, the UP/DOWN arrow pushbuttons are used to
increase/decrease the delay time. The delay time can be adjusted from 0 to 24 hours. The first hour can be set in
increments of 10 minutes; afterwards the delay time is incremented by the hour. The delay time setting becomes
active when the unit is in the SUSPEND mode and the RECORD buttons are pressed. Then, the delay time begins
to count down to zero, which is visible on the LCD display. When the countdown reaches 0, the CD47C returns to
its normal operation, setting thresholds values and detecting passages. The countdown can be bypassed by pressing
the RECORD buttons simultaneously. A new delay time needs to be entered for each Delay ON routine. The
default Delay ON setting is 00:00:00.

In Figure 22, Setting the Active Receive Channel(s), the UP/DOWN arrow pushbuttons are used to cycle the
selection of the Active Channel(s) from BOTH, MAGNETIC, TRANSMITTER. Any Passages or Ignored events
that are detected by the Active Channel(s) is saved to non-volatile Flash memory. Any data on a channel that is not
active is ignored. The default Active Receive Channel(s) setting is BOTH.
Setting the LCD Contrast
Figure 23, Setting the LCD Contrast
In Figure 23, Setting the LCD Contrast, the UP/DOWN arrow pushbuttons are used to increase/decrease the contrast
setting of the LCD display. Pressing ENTER accepts the setting, pressing ESCAPE retains the current setting. The
default LCD Contrast setting is 36.
Setting the Serial Number
Figure 24, Setting the Serial Number
In Figure 24, Setting the Serial Number, the UP/DOWN arrow pushbuttons are used to increase/decrease the
CD47C‟s Serial Number. The unit‟s Serial Number is displayed on the LCD display and is used by CDI‟s Marker
Software to identify the CD47C and tag its data when downloading for analysis. The Serial Number of every
CD47C is initially set by CDI during production. While CDI has other means it can use to track a CD47C that has
had its Serial Number changed, operators should use caution when using this feature.
Acquiring Current GPS Information
Figure 25, Acquiring Current GPS Information
In Figure 25, Acquiring Current GPS Information, the UP/DOWN arrow pushbuttons are used to toggle between
NO/YES and pressing ENTER selects and saves the setting. After selecting „YES‟, the CD47C will immediately
attempt to acquire new GPS information. Once the new GPS information has been acquired, the CD47C‟s internal
clock is reset, it‟s time slaved to the new GPS time, and the new GPS information is saved into nonvolatile memory.

Although the CD47C‟s internal clock is highly accurate, acquiring new GPS information can enhance the time
calculations during data analysis.
Selecting the Device for Downloading Data
Figure 26, Selecting the Device for Downloading Data
In Figure 26, Selecting the Device for Downloading Data, the UP/DOWN arrow pushbuttons are used to toggle
between RS232 (serial download cable) or Bluetooth (wireless). Pressing ENTER selects and saves the setting. The
CD47C is equipped with an internal Bluetooth transmitter, while the serial download cable is a standalone cable that
mates to the CD47C and the serial port of a personal computer or laptop. Refer to Downloading Data for detailed
information. The default Device for Downloading Data is Bluetooth.
Resetting File Memory – deletes memory and retains current configuration

RECORD and SUSPEND modes.
Downloading data from a CD47C requires that CDI Marker software, version 3.179 or newer, be installed on either
a pc or laptop computer. Version 3.179 or subsequent versions can be installed on computers running Microsoft
Windows 98 2nd Edition/2000/XP SP2/Vista operating systems. Version 3.179 or subsequent versions are backward
compatible with earlier versions of the CD47 Benchmarkers. Customers that already have Marker installed can
determine its version by going to About Marker… from the Help pull down menu. A CD with the latest version of
Marker is shipped with new orders of the CD47C. CDI also provides customers with an internet link of the latest
version for immediate download. An extensive help section in Marker can assist the operator if any issues arise
during data downloads or normal operation.
RS232 Serial Cable Downloads
The serial download cable, available from CDI, has a four pin circular connector on one end and a standard DB9
male serial connector on the other. The circular connector mates to a bulkhead connector on the side of the CD47C
and the DB9 to a computer or laptop that has CDI‟s Marker software installed on it. Marker software automatically
handles all serial port settings and the download communications protocol with the CD47C. The user only has to
inform Marker, in the download dialogue window, which serial port to use, refer to Figure 30, Marker Screenshot
during Serial Cable Download.

During the serial cable download, the CD47C‟s top third from right side LED flashes ON/OFF for each data block
that is transferred to Marker. The flashing LED provides an additional visual conformation to the user that a
download is in progress and that data is being transferred successfully.

Bluetooth Wireless Downloads
The CD47C is equipped with a Bluetooth Version 2.0 serial module that supports wireless downloads. The module
is a Class 1 device with a possible range of 300 meters. The actual download range may be reduced by the
limitations of the pc/laptop computer‟s Bluetooth device and/or environmental conditions. The pc/laptop computer
running Marker software needs to be equipped with a properly installed and functioning internal or external
Bluetooth device. CDI can provide its customers with an external USB Bluetooth module or recommend a
compatible device.
Wireless downloads from the CD47C are both safe and secure. Maintaining security was paramount during the
design of the Bluetooth interface for both the CD47C and Marker software. First, Marker only recognizes CD47C
Bluetooth devices and ignores all others. Second, pairing of devices requires a specific and proprietary passkey.
Third, the transmitted data is encrypted. Fourth, the data format and communication protocol is unique and
application specific. This means that the CD47C‟s Bluetooth device does not conform to typical Bluetooth profiles
and is therefore more secure.

The user can select the Bluetooth device for downloading data in the Menu System (refer to Accessing the Menus).
Once Bluetooth is selected, the CD47C will automatically configure and control all wireless downloads. The only
user intervention required is to issue the START TRANSFER in Marker software.

Bootloader – updating the CD47C’s operating system Warning - caution should be used when accessing the Bootloader, the CD47C’s operating system could be
erased!
The purpose of the Bootloader is to erase the operating system that is currently in memory and replace it with a new
one. The Bootloader allows customers to update the CD47C‟s operating system quickly and easily using the RS232
download cable and the serial port of a personal computer or laptop.
A terminal emulation program that supports communications over the COM port will need to be installed on the
personal computer or laptop. HyperTerminal is an emulation program that is supplied with Microsoft Windows and
is suitable. In the emulation program, configure the COM port for: Bits per second – 57600, Data bits – 8, Parity –
None, Stop bits – 1, Flow control – None, and select the COM port that the download cable is plugged into.
A CDI supplied .hex file contains the CD47C‟s operating system. The .hex file is small, under 200K, so it can
easily be attached in emails for quick distribution to customers and downloads to the CD47C.
Use the following procedure to update the CD47C‟s operating system:
1. Connect the download cable to the CD47C and serial port of the pc/laptop.
2. Configure and select the COM port in the terminal emulation program, 57600, 8N1, NONE.
3. While pressing the CD47C‟s LEFT most GREEN pushbutton power ON the unit.
4. Verify that LDRv1.1>_ is displayed in the emulation program.
Warning – the following step will erase the operating system!
5. Press the CD47C‟s RIGHT most RED pushbutton.
6. In the emulation program, select Transfer, Send Text File and select the CDI supplied .hex file.
The CD47C will issue a series of beeps during the download and the process will take about 30 seconds to complete.
Once the download is complete the CD47C will immediately begin its normal startup routine, beeping twice and
displaying the CDI logo on the LCD display. Verify that the Firmware Version displayed in the CD47C‟s startup
window agrees with the version of the downloaded .hex file.
