Connection of Remote Unit
A radiotelephone is connected to a remote unit, such as remote terminal, DSC, and NBDP
in Furuno MIF format of which TX/RX data lines are heard-wear selectable for current
loop or RS-232C signal.
Maximum four remote units can be connected by using a distributor DB-500 as shown in
Figure below.
Each port on the DB-500 can support Current loop and RS-232C signals according to the
type of the REMOTE board fitted in the DB-500: REMOTE A board for RS-232C and
REMOTE B board for Current loop. Each port has own REMOTE board.
The remote unit ports on the DB-500 have priority;
REM-2 > REM 3 > REM-4 > REM 5
There are two types of the DB-500.
DB-500: Standard type
REMOTE-1 (IN) ----- C.Loop (REM B)
REMOTE-2 (OUT) ----- C.Loop (REM B)
REMOTE-3 (OUT) ----- C.Loop (REM B)
