Control Unit (XCU-44)
The X-System Control Unit (CU) is mounted in the front rack of the Sideline Cart. It serves as the foundation of the wireless
communication system. The CU contains no radio and is frequency agnostic, which sets the groundwork for a multi-
frequency capable system. For maximum flexibility, any CU can access, control, and monitor any active device across X-Net.
The X-System Control Unit is the foundation for X-Net. A separate Radio Transceiver (RT) is required for RF communications.
The Control Unit is capable of supporting all models of X-System Radio Transceivers at the same time (900MHz or 2.4GHz)
