Connecting the RF Deck by Using a D-sub 25-pin Cable
Caution
Connect a D-sub 25-pin cable to the transceiver after confirming that the FPU data for Mobile Relay Station is
written. A D-sub 25-pin cable may malfunction if the D-sub 25-pin cable is connected to the transceiver with the
FPU data for Mobile Relay Station not written to the transceiver.
To
use the Mobile Relay Station function, 2 RF Decks need to be connected by a D-sub 25-pin cable, and a Control Head
needs to be connected to one of the RF Decks.
