Master/Slave Configuration
One powerful configuration that NAT's Tac/Com controls support is the master/slave
configuration. In this configuration, two controls can be active at the same time (flight
crew and medical crew, for example), and both can select channels and radios. The
extraordinary aspect of this interface is the fact that this interconnect requires only 6
additional wires to give full support to both stations. Dual controls wired with other units
often require hundreds of wires, and still permit only a single control to be active at one
time.
A typical master/slave interconnect is illustrated below for clarification. Many
variations are possible, and the controls can be 2, 3 or 4 radio types, if required.
