2.5.1 J4 | REDUNDANT LOOP Connector

The J4 | REDUNDANT LOOP connector is located near the waveguide output and is used only in
configurations where the SSPA controls waveguide switching.
In alternate configurations, such as "chain switching", another system block or external M&C
controls the waveguide switching. In this case, the connector remains unused and the protective
cap should be left attached. The pinout specification is shown in Table 2‐5.
