Integrating the VIC-1 with other equipment

Integrating the VIC 1 with other equipment is quite easy really.. there are some common connections that can be used. the biggest worry here will be to isolate the 12 volt radios and the 24 volt vic1, you cant simply hook these things together and expect them to not fry one another.

NOTE: One very important thing to note is that the VIC1 is 24 Volt and most Civilian radios are 12 Volt, you need to isolate them from each other if they are on connected to the system.

There are some common things that people want to do... 1) Hook up a FM radio, Satellite receiver, scanner, ipod, or other MP3 player. RX (receive) ONLY 2) Hook up a Transceiver, like a CB, FRS/GMRS radio, Ham Radios etc. This is TX (Transmit) / RX

Receive Only Inputs

To integrate something that is RX only, the easiest thing to do is to use the J508 4 pin power jack. Although this is a power input when the intercom is in Internal (no military radio hooked up) mode, this is NOT used when a MT-1029 is on the system. this is because the VIC1 will get its power from the radio mount on J501 or J503. This plug doubles as an RX input source.

To hook up an input source simply use this hookup

NOTES: - Need to verify the impedance of T-1 to insure proper matching, this is really here for unity and to maintain isolation

SEE AM-1780 for Jack details

TX / RX

J501 or J503 must be used, they use the CX-4723 - 18 Pin Cable.

RX only

J508 or J510

Example of My integration

These are some photos of my integration of the VIC1 with civilian radios, i used the circuit defined in Properly Hook Civilian Radio to VIC1

ProtoType circuit and additional wiring.

This uses the 18 Pin "C" Radio integration for full transmit and receive support. the DB9 plug is so that i can easily hook to many different radios that i have put a "pigtail" DB9 in.

This is one of the radios. In this case its a EF Johnson, business band radio, programmed with the GMRS/FRS frequency set.
