Telex BP-1002 - Manual (Page 8)

4 Introduction
5. Sidetone Control - When using a headset, this control adjusts your own
voice level heard in the headphones. To adjust the
level, tap the Talk button once to turn ON the headset
microphone. Then, use a small Phillips head
screwdriver to increase or decrease your voice level
while talking into the microphone. (This control is
accessible by removing one screw in the belt clip.)
6. Headset Connector -
This connector accepts a four-wire Telex
®
boom-
microphone headset.
7. Intercom Channel
Connectors - On the BP-2002, intercom channels are connected via
a pair of 6-pin connectors (one male and one female).
The male and female connectors are wired together in
parallel, providing a “loop-through” at each
connector pin. Use one connector to connect to the
intercom channel. Use the other connector to “daisy
chain” a cable to the next beltpack or other station on
the channel.
Local Power Input - Normally the BP-2002 is
powered from the intercom system and will turn
ON with the intercom system. The BP-2002
beltpack may also be powered from an optional
power supply (21-30 VDC) connected between
pin 2(+) and pin 1 (-) of the intercom channel
connector.
8. Intercom Channel
Connectors - On the BP-1002, the intercom channel is connected
via a pair of 3-pin connectors (one male and one
female). The male and female connectors are wired
together in parallel, providing a “loop through” at
each connector pin. Use one connector to connect to
the intercom channel. Use the other connector to
“daisy chain” a cable to the next beltpack or other
station on the channel.
