ANTENNA CONNECTOR
Connects to a marine VHF antenna with a PL-259 connector.
A key element in the performance of any communication system is the antenna. Ask
your dealer about antennas and the best place to mount them.
CAUTION:
Transmitting without an antenna may damage the transceiver.
5
GROUND TERMINAL
Connects to a vessel ground to prevent electrical shocks and interference from other
equipment occurring.
Use a PH M3 × 6 screw (user supplied).
■
Connecting to the MA-500TR
Connect the transceiver to the high-density D-Sub 15-pin connector of the MA-500TR
using the OPC-2014* cable. After connecting, an Individual DSC call can be made to the
AIS target using the transponder without entering the target’s MMSI code.
* The OPC-2014 is supplied with the MA-500TR.
z
Connect each lead to the appropriate lead of the OPC-2014 as follows.
•Listener A (Data-H) (Yellow): To lead 3.
•Listener B (Data-L) (Green): To lead 2.
•Talker A (Data-H) (White):
To lead 5.
•Talker B (Data-L) (Brown): To lead 4.
■
Fuse replacement
One fuse is installed in the supplied DC power cable. If the fuse blows or the transceiver
stops functioning, track down the source of the problem, repair it, and replace the
damaged fuse with a new one of the proper rating.
Fuse rating: 10 A
■
Cleaning
If the transceiver becomes dusty or dirty, wipe it clean with a soft, dry cloth.
DO NOT
use harsh solvents such as Benzine or alcohol, as they will damage
the transceiver’s surfaces.
