It is an extremely configurable remote (high-end dealer programmable type model, similar to Control4, Crestron, etc. type genre)
Here are 3 configuration options for the IR codes it has - any clue on if I might try changing some of these? I can also dump the actual IR codes it is sending for one key if that would help...
Minimum Repeats (set to 1 by default)
The number of times that the repeating part of the IR code is sent. Some infrared receivers need a command to be repeated a certain number of times to work properly, and some may not work properly if the command is repeated at all.
Frequency (38.0 Khz by default)
The carrier frequency of the IR code. You should not need to change this value unless directed to do so by Technical Support.
Sustain (Checked by default)
Cause the IR code to repeat for as long as the button is held down. Most infrared codes will transmit continuously as long as the button is held down, but some infrared receivers may not work properly if the command is repeated at all. If the Sustain button is checked, the code will be transmitted for as long as the button is held down, or the Minimum Repeats times, whichever is greater. If the Sustain button is not checked, the code will be transmitted only the Minimum Repeats number of times regardless of how long the button is held down.
