A
Connector
Description
A
Network audio out. If monaural audio is used, make certain the output connections
match the input. IE. If the left side is used for in use the left side for out. 600-Ohm
output impedance.
B
DTMF audible cue tone positive signal, low Z unbalanced. Range –20 dB to +0 dB
C
DTMF audible cue tone and GPI ground.
D
GPI (Contact Closure) input.
E
"On Air" Normally Open contact closure. Closes during insert.
F

J
Network audio in. If monaural audio is used, make certain the input connections match
the output. IE. If the left side is used for in use the left side for out. Non-terminating
input. Connect an external resistor or select –6 dB in the NetSet to terminate. See
page 8 for more details.
