JK Audio Broadcast Host - Manual (Page 13)

Remote Control Jack
The RJ-45 jack on the back of the Broadcast Host provides connection to an
optional JK Audio Guest Module 1 remote control, or it can be wired to the switch
contacts on your broadcast console. Do not connect this jack to the network port
on your computer.
RJ-45 Pinout
:
1: Ground
2: Call / Drop Control (main control pin)
3: Ring / OH LED
4: DTMF Input
5: +4.3 VDC
6: Reserved
7: Reserved
8: Reserved
Momentarily connect pin 2 to pin 5 (power) through a 100 ohm ¼ watt resistor
to take Broadcast Host off-hook. Momentarily connect pin 2 to pin 1 (ground)
through a 100 ohm 1/4watt resistor to release (Drop) the phone line. Pin 3
contains a 4.3 VDC, 40 mA current limited output to drive a signal LED. We
suggest adding a 200 ohm ¼ watt resistor in series with an LED connected to
ground. Pin 5 supply output is current limited to 100 mA with a resettable fuse
for use with the Guest Module and pin 2 connections. Do not attempt to power
additional circuitry from this pin.
