is being used. Set MBT equal to N to disable that option.
Set SPEED equal to 38400.
Set STOPBIT equal to 2.
Set the RXID equal to one and TXID equal to two at the Master End. At the remote or Slave End,
set the RXID equal to two and the TXID to one. The relays use these addresses so that the master
relay only receives messages sent by a relay with the matching transmit address and vice versa.
Set TXMODE equal to P (Paced).
To connect the relay to the radio, use an SEL-C285 cable, DB-9 male to DB-9 male straight-
through. If complete electrical isolation is desired between the radio and antenna and the relay’s
EIA-232 communications port, use the SEL-2815M Fiber-Optic Transceivers and fiber-optic
cable to connect the relay to the radio as shown in Figure 1.

ONNECTIONS
The FGR-115MB has settings that require adjustment prior to installation. Invoke the setup
program by connecting the radio to any terminal emulator program, using the DB-9
straight-through cable supplied with the radio. Set the terminal baud rate to 19200, and put the
radio in setup mode by pressing the Setup Button; when setup mode is invoked, all three LEDs on
the radio turn green, and a menu is displayed on the terminal screen as shown below.
