Global Cache GC-CGX IR Converter Cable, GC-100 to XantechThe GC CGX is used to connect a Global Cache IR output (GC 100 or iTach) to a Xantech IR input. Global Cache IR outputs are converted to meet the IR input requirements for a Xantech IR distribution environment. IR signals from 30KHz to 72KHz can now be sent through an existing Xantech IR installation directly from one of our units. The GC CGX is optically isolated to ensure circuit isolation and protection.
