So I'm attempting to run a GentLED Plus IR trigger via Radian port for my 5DM3. I have a 2 position switch mapped to Ch 9 that I'm attempting to set up. So I inserted the IR cable in the correct direction, into port 2 of my tilt Radian. I then opened the Radian software connected and read my tilt settings. Then set the Aux to 9 to represent the channel in which the switch was mapped. Then wrote the settings. Still in the Radian software, I attempted to trigger the swtich to see if everything is working correctly. I get no response from the aux.... everything else works as it should. I then opened MKTools to verify that it was ch 9..... and it is. What am I missing?
