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.

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.

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.
