Relaying the Received Signal (Mobile Relay Station)
Mobile Relay Station
is the function to relay the received signal by 2 RF Decks in a Multi RF Deck structure.
If this function is used, as shown in the diagram below, if RF Deck 1 transfers the signal received from Transceiver A to RF
Deck 2, the signal can be transferred from RF Deck 2 to Transceiver B.

To use this function, the following configurations and RF Deck connections are required:
0
By using KPG-D1/ D1N, configure the 2 RF Decks that activate
Mobile Relay Station
, and configure a
Mobile Relay
Station
Zone-channel for each RF Deck. (Refer to
Configuring Mobile Relay Station
0
By using KPG-D1/ D1N, assign the functions to enable
Mobile Relay Station
to the
PF
key and communication port.
(Refer to
Configuring Mobile Relay Station
.)
0
Connect the 2 RF Decks that activate
Mobile Relay Station
by a D-sub 25-pin cable. (Refer to
Hereinafter, the RF Decks configured with a
Mobile Relay Station
Zone-channel are referred to as “RF Deck 1” and “RF
Deck 2”.
Note
0
Only a channel in an Analog Conventional system, NXDN Conventional system, or P25 Conventional system can be
configured as a
Mobile Relay Station
channel. However, a channel with “Mixed” configured in
Channel Type
cannot be
configured as a
Mobile Relay Station
channel.

The configurations of the following need to be the same for each channel configured in the 2 RF Decks that activate
Mobile Relay Station
.

If
Mobile Relay Station
is used, a delay of up to approximately 1 sec may occur in audio communications from the
transceiver.
