INSTALLATION OVERVIEW 1. Test the radio for functionality. 2. Connect the CAD modem to the radio per the Hardware Installation Section of this manual. 3. Program the CAD software and modem per the Product Programming Section of this manual. * Midian is not responsible for any damage/loss resulting from the use of Midian’s products.
GENERAL INFORMATION
Midian’s CAD Series products work with Midian’s ANI-F or an ANI equipped radio to display ANI and Emergency ANI to identify which field unit is being keyed. The following is a list of benefits provided by ANI systems: • Allows dispatchers to know who he or she is talking to. • Identify system abusers. • Identify emergency conditions. • Assign calls fairly. In addition to decoding ANI and ENI, Midian’s CAD-500 offers selective calling for functions such as individual call, group call, disable/enable, etc. These functions can be used with a radio capable of these functions. Motorola’s MDC-1200: Motorola’s MDC-1200 is a 1200 baud mobile data FFSK signaling format used by Motorola for ANI, status, selective call, radio disable/enable, query and spy.

HARDWARE INSTALLATION Be certain to follow standard anti-static procedures when handling Midian products. For installation instructions for a particular radio, please consult Midian’s application notes for the CAD if available. P1-1 – Ground – Connect to ground in the base station. P1-2 – B+ - Connect to a 7.5-15 VDC source in the base station or from an external power supply. P1-3 – PTT Output – This open collector provides a ground during PTT. P1-5 – Squelch Output – Connect to a squelch point in the base station that mutes the speaker. P1-8 – Alarm Output – This connection is optional as the PC will give an audible tone. This output goes active whenever an emergency status is received. The transistor Q4 provides an open collector to ground to trip a bell, sonalert, etc. It is necessary to install a jumper from the collector of Q4 to P1-8. P1-9 – COR Input – Connect to a point in the radio’s squelch or CTCSS circuit that changes logic level when a carrier is detected. If a high level is provided, move R40 from its pull up to its pull down position. A radio whose squelch circuit provides a logic-low or high can readily turn Q1 on and off. If the point only makes a small change in voltage, it may be necessary to adjust the values of R39 and R40 to Q1 to change states. If the COR is not being used ground this input and program the COR polarity as ground. P1-10/P1-11 – RX 600-Ohm Balanced – Optional – This is a 600-Ohm balanced input that is used when directly connected to the RX line from the base station in a remotely controlled base station over a dedicated phone line. P1-12 – RX HI-Z Input – Connect to the receiver audio output of the base station, preferably after the CTCSS high-pass filter. The following connections are only needed when encoding. P1-4 – Trunk Delay Input – This input prevents the modem from transmitting until a channel has been acquired. Hook to a point in the radio that provides an output after the channel has been acquired. P1-6 – TX Audio Output – Connect to the MIC-High in the radio. Removing JU4 and installing R81 with a value equivalent to the required impedance can change the output impedance. P1-7/P1-8 – TX 600-Ohm Balanced Output – Optional – The CAD must be ordered with the CAD Option A for this output. Connect this output to the TX side of a 600-Ohm balanced audio source. If using this feature the Alarm Output is not available and JU8 should be removed. P3 is the USB connector. The following are the pins used on the optional Female DB-9 connector P2 (RS-232). P2-2 – TX Output P2-3 – RX Input P2-4 – Data Terminal Ready P2-5 – Ground P2-6 – Data Set Ready P2-7 – Clear To Send P2-8 – Request To Send

HARDWARE ALIGNMENT CAD-500: Apply a signal that fully quiets the receiver, modulated by a 1000 Hz tone at ±3.3 KHz (wideband) to the receiver (1.65 kHz for narrowband). While monitoring TP1, adjust R2 for 650 mVpp (230 mV RMS). Output Level: Start the CAD-500 software and command the unit to send data. Adjust R-78 for a deviation of ± 2.8 - 3.0 KHz on the system transmitter.
SOFTWARE INSTALLATION Insert the CD into the CD-ROM drive and close the drive. The CD will auto-run. Click on the side menu bar for miscellaneous software and select the CAD software. Follow the set-up procedures. For detailed information on the software, please refer to the online help.

TECHNICAL NOTES
Radio Compatibility: Midian has taken the utmost care to ensure the CAD integrates with the radio with minimal impact to the features of the radio. However, some features may not be available in the radio when a CAD is used. If a feature is not available, please contact Midian to see if the feature can be added. International Windows Versions: Even though Midian has worked to make this product internationally compliant, Midian recognizes that there may be additional issues to be resolved.
