Model 1716 Jumper Settings
Jumper Name/Signal Description
JP1 Carrier Detect
A = 47k pull-down to ground
B = 47k pull-up to +12 V
dc
JP2 Serial Port Power
Connects +12 VDC (fused) to J2 Pin 6 of RS-232
Connector (DB9)
JP3 Push-To-Talk A = PTT completes the connection between P3 Pin 3
and Pin 4.
B = PTT provides a ground indication on P3 Pin 3.
JP4 Push-To-Talk IN = Push to Talk provides a +5 V
dc
pull up on release.
OUT = Push to Talk goes to open upon release.
JP5 Test A 1800 Hz Test Tone — See Table 20 for instructions
JP6 Test B 1200 Hz Test Tone — See Table 20 for instructions
JP7 Receive Audio Gain A = Low 1x gain on Receive Audio
B = High 10x gain on Receive Audio
JP8 External Audio
A = External Audio Source Input
B = No External Audio
JP9 Transmit Audio
IN = 50 impedance
OUT = 600 impedance
