FULL DUPLEX (4-WIRE)
To connect the diver in Full Duplex (4-Wire) mode, connect the communication
umbilical wires to the DIVER MICROPHONE and DIVER EARPHONE jacks as
shown in wiring diagram in section 3.6. If the umbilical uses a banana plug, simply
insert the plug into the correct binding post jack. Verify that it is firmly and
completely seated. This may require that the external plastic nut be tightened. If
the umbilical uses bare wire ends, loosen the external plastic nut of the binding
post jack. Either insert the bare end of the wire into the hole in the metal shaft of
the binding post or firmly wrap the wire around the shaft. Tighten the nut until the
bare wire is firmly fastened by the nut. The nut should not be fastened on the
insulation of the wire nor should any of the bare wires touch. If the AUDIO
AUXILIARY INPUT is to be used to deliver entertainment to the diver, then the
diver must be wired in Full Duplex (4-Wire) mode. The diver microphone will be
louder in Full Duplex (4-Wire) mode than in 2-Wire mode. This can be a significant
advantage when using longer dive umbilical cables.
To use Full Duplex (4-Wire) mode, the tender must use a headset and connect per
the instructions in 3.2. The tender will have to use the PUSH-TO-TALK BUTTON
to communicate if the diver is in 2-Wire mode. The tender can also use the PUSH-
TO-TALK BUTTON to cut off the AUDIO AUXILIARY INPUT signal from the diver
even if the tender is connected in Full Duplex (4-Wire) mode. When the tender
uses a headset, the SPEAKER SWITCH should be turned off to prevent acoustic
feedback. Acoustic feedback can also be avoided by moving the tender away from
the 2810E by using the Amron Model 2822-28 Remote Walk-and-Talk Module. In
this way, the PANEL SPEAKER can allow other members of the diving crew to
monitor the dive operation or to communicate to the diver by pressing the PUSH-
TO-TALK BUTTON and talking into the speaker.
