GC-CXG

Converter

The Global Caché GC-CXG converts Xantech and Xantech compatible IR
emitter output voltages to the proper levels required by the Global Caché GC­IRE IR Extender. The GC-IRE translates IR signals to serial ACSII text, which
can be read by a PC serial port or over the network utilizing the GC-100 Network
Adapter's RS232 serial port. Simply plug the 3.5mm stereo jack into a Xantech
distribution box (emitter output) and the other end into the GC-IRE. The GC-IRE
is responsible for filtering out noise and providing good IR commands before
being converted to serial ASCII text. IR commands are represented as comma
delimited ASCII text. (See the API specification for IR serial formats on Global
Caché’s website.) In the following installation, a SpeakerCraft AT-1.0 emitter
output provides the IR signal for transmission over a network. First, the GC­CXG converts the IR signals for the GC-IRE; then the GC-IRE filters and
serializes the IR data for the RS232 serial port on the GC-100. Finally, the GC­100 transmits the serial IR data over the network.

The GC-CXG used with a SpeakerCraft Amplified Terminator and IR Receiver

The GC-CXG is optically isolated to avoid noise and ground loop issues found
when systems are powered by multiple sources. When used with the GC-IRE,
the GC-CXG requires no power supply and supports the full IR frequency range
from 30 KHz to 500 KHz. When extension cables are needed for longer runs, to
avoid high-frequency degradation they should not be used between the GC-IRE
and GC-CXG.
