Channel Control Logic (Turrets)
The pins on the ‘Logic’ connector are used to remote control the mod-
ule for applications such as studio talk turrets. Controls include Chan-
nel On, Off, Tally LED driver for on-off status, Talk to Console, and
momentary Cough logic. All control is by dry closure to ground. The
tally LED should be connected through a 510 ohm resistor to ground.
