The IR Integration Cable is designed to allow you to connect the IR blaster output from almost any device (such as a third party control system) directly into the IR receiver input of a HDanywhere mHub system. This is particularly useful with video over distance systems as it allows a direct, more reliable, connection from third party product when making use of the forward IR path. The input socket is a 3.5mm 3 pole connector and is intended to be connected to the IR blaster output of the item you are connecting to. The socket is optically coupled such that the polarity and pin configuration will not affect operation. It will work with any connection whether positive or negative. This model is for use with MHUB 4K Pro devices.
