Tender Microphone Jack
–
This is a dual banana jack (color-coded red) that
functions as the microphone input from the tender's headset. It is only used if the
tender is in Full Duplex (4-Wire) mode. On the 2830R/24, the TENDER
MICROPHONE VOLUME control adjusts the sensitivity of the input.
4.2.3
Push-To-Talk Jack
–
This is a dual banana jack (color-coded yellow) that allows
for remote keying of the push-to-talk function of the 2830R/24. The difference
between using the PUSH-TO-TALK JACK and PUSH-TO-TALK BUTTON is that
the button allows the tender to communicate using the PANEL MICROPHONE.

Diver Controls
The following controls are located on the front panel in the individual diver sections.
4.3.1
Diver Microphone Volume
–
The 2830R/24 has a separate microphone
volume control for each diver. This sets the gain for the diver’s microphone
amplifier and controls the diver’s volume level to the tender and other diver.
4.3.2
Diver Earphone Volume
–
The 2830R/24 has individual earphone volume
controls for each diver. This allows the tender to set the best volume level
for each diver.
4.3.3
Push To Talk Diver
–
There is a separate PUSH-TO-TALK momentary
switch for each diver. Normally used in 2-Wire mode, this control allows the
tender to talk to only one of the divers. The diver selected will hear both the
tender and the other divers. It can be used in Full Duplex (4-Wire) mode to
cut off the microphone of an individual diver.
4.3.4
Crosstalk
–
There is a separate CROSSTALK momentary switch for each
diver. Normally used in 2-Wire mode, this control allows the selected diver
to talk to the other divers while the tender monitors the conversation.
4.4
Diver Connections
4.4.1
Diver Microphone
–
This is a dual 5-way binding post jack (color-coded red) that
functions as both an output (earphone) and input (microphone) for the diver as
controlled by the PUSH-TO-TALK BUTTON and PUSH-TO-TALK JACK. Using this
connection, the diver can be wired in either 2-Wire or Full Duplex (4-Wire) mode
regardless of the mode used for the diver.
To connect the diver in Full Duplex (4-Wire) mode, connect the diver microphone to
this jack and the diver earphone the DIVER EARPHONE jack as shown in the
wiring diagram in section 4.9. The diver can use this mode even if the tender is
wired in 2-Wire mode.
To connect the diver in 2-Wire mode, connect both the diver microphone and
earphone to this jack. If the diver umbilical uses banana plugs, simply stack both
plugs into this jack as shown in the wiring diagram in section 4.8. In this mode, the
diver microphone will be active and heard on tender headset and/or PANEL
