The M905 IR Control Option Upgrade from Grace Designs is a user-installable front panel and headphone jack for the Remote Control Unit (RCU) and once installed allows the M905 Monitor Controller to be wirelessly controlled by infrared remote. Compatible remotes include the Grace Design A903RCU, Apple Remote, and iOS/Android control via the Logitec Harmony Remote.
Units with the serial number 905294 or below will require soldering, while 905295 or above have a header on the board that the IR receiver simply plugs into. Once installed, the M905's firmware must be upgraded to v1.13 or higher.
