5.10 TX & RX Waveguide Switch Interface (J5 & J9)
These ports provide 48Volts for switching the RX and TX Waveguide switches. For TX
waveguide switching, connect the CAR5904 cable between the J5 of the OMS11 to the TX
waveguide Switch. For RX waveguide switching, connect the CAR5904 cable between the J9 of
the OMS11. The chart below identifies the J5 & J9 pinouts on the OMS11 and the mating
connector pinout for a Sector Microwave Switch. Connector information and pinout descriptions
are identified below. Refer to Table 5-14 and Figure 5-3. CAR5904 is supplied by Radyne when
waveguide switching hardware is supplied by Radyne.
