Function Remarks
J1-1 J11-1 TX ON LOW
COMMAND
Momentary connection to ground sets the system
to LOW POWER ON mode. Maximum open
circuit voltage is approximately 15VDC
J1-2 J11-14 TX ON HIGH
COMMAND
Momentary connection to ground sets the system
to HIGH POWER ON mode. Maximum open
circuit voltage is approximately 15 VDC.
J1-3 J11-2 TX OFF COMMAND Momentary connection to ground sets the system
to OFF mode. Maximum open circuit voltage is
approximately 15 VDC.
J1-4 J11-15 SPARE COMMAND Not used.
J1-5 N/A MASTER FAIL-
SAFE
Connection to +15 VDC source at J1-25 through a
normally closed contact set, in customer
equipment, allows transmitter operation. If not
used, a jumper must be installed between this
terminal and J1-25.
J1-6 N/A MASTER
INTERLOCK
Not available for use. This input is used for the
combiner reject load in this configuration.
J1-7 J11-4 R/C STATUS Provides a connection to ground through 200
Ohms when the REMOTE mode has been selected.
J1-8 J11-17 FWD PWR SAMPLE Provides 0-4 VDC sample through 2k Ohms of the
RF forward output power.
J1-9 J11-5 RFL PWR SAMPLE Provides 0-4 VDC sample through 2k Ohms of the
RF reflected output power.
J1-10 J11-18 REJ PWR SAMPLE Provides 0-4 VDC sample through 2k Ohms of the
RF reject load power.
J1-11 J11-6 IPA A PWR
SAMPLE
Not used.
J1-12 J11-19 IPA B PWR
SAMPLE
Not used.
J1-13 J11-7 SWR FAULT
STATUS
Provides ground connection through 200 Ohms
when the reflected output RF power level has
exceeded the safe operating level, and the system
controller has terminated transmitter operation.
Can sink 25mA to ground and is suitable for use
with circuits up to 15 VDC.
