Sum Fault Input
Refer to Figure 12. The Sum Fault input comes from the other amplifier.
The Sum Fault input provides a pull up resistor of 100K to + 13V for an
open collector input at J6-M. A logic HI is present when the other
amplifier faults.
Figure 12, Sum Fault Input
Sum Fault Output
Refer to Figure 13. The Sum Fault output is an open collector output at
J6-L. The output transistor will be off when this amplifier faults.

Wave Guide Switch 1 and Wave Guide Switch 2 RF Inhibit
Refer to Figure 14. The Waveguide Switch RF Inhibit input provides a pull
up resistor of 100K to + 13V. An input HI is required when a RF Inhibit
command is received from Waveguide Switch 1 at J6-G or Waveguide
Switch 2 at J6-K. For normal operation pins J6-G and J6-K must be
grounded through a jumper to either J6-N or J6-P.
