CENTRAL UNIT
The TS-920RC is a Central Unit of the Infrared Conference System that allows easy installation and flexible layout.
By connecting 1S—-905/907 IR Transmitter/Receiver, T5-920RC can control the Chairman and Delegate Units via
wireless infrared signal.
It features the installation confirmation function that allows the connection status of IR
Transmitter/Receiver and Chairman/Delegate Units to be verified, and the voting function. The 15-920KC is also
