If you need to extend your hard wired IR distribution system over CAT5 here’s a really useful set of adaptors. The Keene Electronics 3.5mm jack plug to CAT5 adaptors for IR extenders are under £6 and allow you to easily connect your IR transmitters and receivers to any CAT5 outlet with a patch lead…
A set of two short (25cm) line adaptors, one with an RJ45 line socket to a 3.5mm stereo jack plug, and the other with an RJ45 line socket to a 3.5mm stereo jack socket.
This is designed to allow CAT5 cable to be used to extend the distance between the IR receivers and the Keene IRBKIT and IR Commander infra red distribution systems.
To use simply plug the IR receiver in to the 3.5mm jack socket of one adaptor and the 3.5mm plug of the other adaptor goes into the IR receiver input of your IRBKIT or IR Commander. Connect your Cat5/6 (standard wired network cable) in between the adaptors and that is it. Using this method it is possible to remote mount IR receivers at distances of up to 100m.
