Hi There,

I have a customer who has gone out an bought 4 DMTech LM20D's.

I have a MX-700 and I have downloaded the latest software but there doesn't seem to be any codes for this manufacturer.

I have the original remote control for the screens but I am trying to hunt down the "discrete" codes for changing AV sources. On the remote control, you can toggle/skip through the sources but not jump directly from one to the other, which is what I need.

Has anyone got any thoughts on how I can track down these codes please?

Many thanks

Trev
