Why is my IR Extender not working with my Gefen Switcher?
To use the IR Extender, the Switcher must be in remote mode. Switcher has two different modes: local and remote. Switcher ship in the default local mode but can be changed to remote mode by adjusting the jumpers on the board or dip switches under the unit. Instructions for each particular switcher are located in the product manuals. Please contact Gefen Tech Support for further assistance on changing to remote mode.
