The receivers have many controls, including audio adjustments, that are available under
Remote RS-232 and USB port Simple Instruction Set (SIS) control and PCS. Both units
have video, audio, fiber light status, and lost-light alarm indicators.
NOTE: The FOX3 receiver is compatible with all Extron FOX3 transmitters. The FOX3
products are not compatible with legacy FOX, FOXBOX, FOX II, PowerCage 401 FOX,
or PowerCage 1600 FOX products.
Fiber Cable Transmission Modes
The receivers are further categorized by the type of fiber optic cable, multimode or
singlemode, which define the effective range of transmission:
Multimode — Long distance, up to 500 m (1640 feet) (depending on the fiber cable)
Singlemode — Very long distance, up to 20 km (12.4 miles)
NOTE: The multimode and singlemode units are physically and functionally identical,
with the exception of the effective range of transmission. In this guide, any reference
applies to either transmission mode unless otherwise specified.
