Front panel UA-3122-030 is for use with LAN-XI Bridge Module Type 3057. It features three input channels with buffered monitor output channels in parallel.

Each channel has three input connectors: one for bridge transducers, one for charge signals and one for direct/CCLD signals. The 15-pin D-sub connectors allow individual configurations of completion resistors to be made directly on the cable plug.

UA-3121-030 and UA-3122-030 are very similar. UA-3121-030 has connectors for differential charge input and UA-3122-030 has connectors for direct or CCLD input.

Note: Only one kind of input per channel can be used at a time.
