Using Optional Infrared (IR) Extender Jack
The IR extender jack is for situations requiring the Matrix Switch to be mounted in a location
where direct line-of-sight is not available. If you have purchased a standard IR extension module,
connect it to the Extend IR jack of the unit and position the module in a manner that allows the
furnished remote to be pointed at it without any obstructions between the remote and the IR
extension module. The cable length will vary according to the manufacturer of the IR extension
module.
Operation using the extended IR module accessory is the same as with the standard IR remote
capability.
