1. Install male Marsh-Marine 4-pin connector in hat/helmet. Attach black and white
wires to binding post and both speakers. Attach red and green wires to leads from
microphone. It doesn’t matter which color goes to which lead. Use 8
-32 x 1/4 SS
screw and nuts, cover each with tape or shrink tubing. You are now finished with the
diving hat/helmet.
2. Install 4-pin female Marsh-Marine connector on diver's end of communication cable.
Connect red and green wires to the light colored pair of communication cable wires;
black and white wires to black pair of communication-cable wires. You are now
finished with this step.
3. Install black dual banana plug to black pair of wires on tender end of diver
communication-cable and attach red dual banana plug to lighter color pair of wires. If
you don’t have red dual banana plugs, red tape will serve to identify that pair as the
microphone circuit. YOU ARE FINISHED!
To setup and check-out the communication link:
1. Attach hat/helmet to umbilical.
2. Attach communication cable to AMCOM diver communicator. Connect the red
banana plug to DIVER MICROPHONE (red) jack and the black banana plug to
DIVER EARPHONE (black) jack.
3. Set the volume controls to mid-range on the communicator. Turn on the
communicator. There may be some acoustic feedback, if that occurs then reduce the
volume until it feedback stops.
4. Don the hat/helmet and start talking. You should hear yourself in earphones. Adjust
the volume as necessary for clear communications.
To revert back to 2-Wire mode, simply remove black banana plug from DIVER EARPHONE
(black) jack and plug it on top of DIVER MICROPHONE (red) plug.
Things to keep in mind when using Amron's AMCOM diver communicators:
With the AMCOM diver communicators you can mix 2-Wire and Full Duplex (4-Wire) modes
of operation. For example, the diver can operate on Full Duplex (4-Wire) mode while the
tender operates in 2-Wire mode. The tender can use the panel speaker to listen to the diver
and talk to the diver by pressing the push-to-talk button and using the panel speaker as a
microphone.
When using AMCOM diver communicators with multiple diver capacity, each diver can be
wired in either 2-Wire or Full Duplex (4-Wire) mode. All divers do not have to operate in the
same mode.
The push-to-talk button overrides the diver conversation by forcing all divers into listen only mode. This
occurs whether the diver is wired in 2-Wire or Full Duplex (4-Wire) mode.
