Remote Talkgroup Steering allows local PSU user to remotely change the TG / channel
currently selected on the MSU by sending a call alert / page to the VR (using the VR ID) and
transmitting a specific NAC.
If Remote Talkgroup Steering is required, the PSU must be programmed to transmit on the
same DVR channel with different NACs, which NACs are then strapped to the desired MSU
modes in the Futurecom Repeater Configurator Mobile Radio Channel Setup screen.

The VR Tx NAC is as programmed and must be matched with the PSU Rx NAC! The PSU is
programmed with various Transmit NACs (used for the steering) but the same Receive NAC (or
F7E). The VR Rx NAC is programmed to match the PSU Tx NAC programming when no remote
mode steering is needed.
