2.1 Vehicle Communications Assembly, Model VCA100

The VCA100 (Figure 2) is mounted in a vehicle and has no operator controls other than

a remote power-on switch. Once initialized, VCA100 operations are transparent to the

operator. Responders need only set their radio equipment to the pre-designated

interoperability channel to monitor or speak to members of other radio networks at the

site. The specific VCA100 model is selected based on the radio frequencies used by

the participating department (see Appendix A).

• LMR: 2-way radio antenna connection, TNC.

• GPS: Reserved for future implementation.

• Ethernet: Factory use only.

• Power: The VCA100 is permanently mounted in a First Responder

vehicle. On/off is a cab-mounted toggle switch.

• Network: Wireless antenna port A, reverse polarity SMA connector.

• Activity Indicator: Indicator light that is on during boot up.
