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.
