NOTE

When two UPEUs are configured in the BBU, the other UPEU is configured in Slot18. The pin assignments for the wires connected to the monitoring ports on this UPEU are the same as those for the wires connected to the monitoring ports on the UEIU.

The EMU and EMUA are used for environment monitoring indoors and outdoors respectively. The EMU and EMUA enable the monitoring of analog values and Boolean signals with the port for monitoring analog inputs, port for detecting the Boolean inputs, and port for controlling the external Boolean outputs.
