Output See Signal Pin 24
12 25 CEX LOCK Digital
output
When the generator is
successfully phase-locked to an
external oscillator, a low (opto-
coupler output) impedance is
created between this pin and
return pin 25. (6 mA max)
See Wiring Diagram 4-11.
13 21 +15 VDC Analog
output
This pin, referenced to ground,
provides a +15 Vdc auxiliary
supply for external use.
See Wiring Diagram 4-13.
14 1 SETPOINT STATUS Digital
output
When the output is equal to the
requested setpoint, a low (opto-
coupler output) impedance is
created between this pin and
pin 1. (6 mA max).
See Wiring Diagram 4-8.
Note: This condition is also
referred to as the generator
being at setpoint.
