2.2.7 Communication Port & Mode Select Switch
NMS-PWR-OUT- This port is used to power the SDR-NMS. If multiple modules are being used in a system, the
SDR-NMS only requires power from only 1 module. This port will connect to the NMS-PWN-IN on the SDR-NMS.
Debug Port- The debug port is used for ADRF testing purposes only.

2.3 Channel Combiner (SDR-CHC)
2.3.1 RF Ports
An optional channel combiner can be mounted directly above the SDR. There are 2 versions of the SDR-CHC.
The SDR-CHC-V supports Cellular, AWS, PCS, and 700MHz. The SDR-CHC-S supports PCS, BRS, and SMR. The donor
portion of the SDR-CHC can be used to split up a combine donor signal. The server portion of the SDR-CHC can be
used to combine the server signals into the Server Sum port. Please contact sales@adrftech.com if you are
interested in purchasing the SDR-CHC.
