Full Duplex (4-Wire) communication is defined as a dual communication path, a signal path
(a pair of wires) for up-link and a signal path (a pair of wires) for down link. A common
example of Full Duplex communication is the telephone. Full Duplex (4-Wire) has the
advantage of natural communication without having to use the PUSH-TO-TALK BUTTON.
This keeps the tender's hands free to perform other task. It does not require the same level
of discipline to achieve clear communications that 2-Wire does. It has the advantage that
neither the diver nor the tender are cut off when the other is talking. Because the diver's
microphone is not connected in parallel with the earphone, the diver is louder and potentially
clearer in Full Duplex (4-Wire) mode. More information on this mode can be found in Section
6, FULL DUPLEX (4-WIRE) - WHAT, WHY AND HOW.
5.4.1 2-WIRE
To connect the diver in 2-Wire mode, connect the communication umbilical wires
to the DIVER MICROPHONE binding post jack on the 2810E as shown in the
wiring drawing in section 3.5. If the umbilical uses a banana plug, simply insert the
plug into the binding post jack. Verify that it is firmly and completely seated. This
may require that the external plastic nut be tightened down. If the umbilical uses
bare wires, 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.
The tender can operate in 2-Wire without a headset or push-to-talk microphone by
using the PANEL SPEAKER as both a speaker and microphone. When the tender
wants to talk to the diver, he presses the PUSH-TO-TALK BUTTON on the front
panel and speaks clearly into the PANEL SPEAKER at a distance of between 4 to
8 inches (10 to 20 cm). When done speaking, the tender releases the PUSH-TO-
TALK BUTTON to allow the diver to communicate.
When the tender uses a headset or push-to-talk microphone, follow the connection
instruction in section 3.2 and in the wiring diagram in sections 3.5 and 3.7. When
using the Amron Model 2405-28 Push-to-Talk Microphone, the tender presses the
push-to-talk button on the side of the microphone and speaks clearly at a distance
of between 1 and 2 inches (25 to 51 mm). When done speaking, the tender
releases the push-to-talk button to allow the diver to communicate.
Whenever either the diver or the tender are connected in 2-Wire, the tender must
use one of the push-to-talk methods when talking to the diver.
