Monitor Output (232J2) - Watkins-Johnson Company WJ-8718-19/FE Instruction Manual

INSTALLATION AND OPERATION WJ-8718-19/FE HF RECEIVER
2.3.1.4 Synchronous Serial I/O (J14)
This 19-pin circular connector is the interface point between the receiver
and remote control equipment. The pin assignments are as follows:
A - DFR GND G - D3 (8)
B - DFR K - TFR j
C - GND V - GND
D - DO (1) R - TC GND
E - Dl (2) U - TC J
F - D2 (4) I

2.3.1.5 Clock Switch (S2)
•
Setting this switch to the INT position selects the internal time base for «
the receiver and provides the internal 1 MHz reference output at Jll. Setting this j
switch to the EXT position deactivates the internal reference so that an external
signal may be applied to Jll.
2.3.1.6 1 MHZ REF (Jll)
When the CLOCK switch is in the INT position, this BNC connector \
provides a 1 MHz, 100 mV rms output into 50 ohms. When the switch is set in the
EXT position, a 1 MHz reference signal of at least 50 mV rms into 50 ohms must be s
applied to Jll to provide a time base for the receiver. •
2.3.1.7 Remote Input (232J1) I
This 10-pin circular connector is the interface point between the receiver
and remote control equipment. The pin assignments are as follows: ; •
