I bought a 202U kit in May of 2019. It is working GREAT in my application. I am just using the two relays and programmed the A and B keys on the transmitters and the relays are setup in standard mode.
I bought another 202U kit today and got it working on a different application, BUT, I wanted to used the unassigned C and D buttons on my existing (and new) transmitters to run the two relays in the new unit.
When I tried to program the C and D buttons on my existing transmitters, I could not get them to be recognized by the new receiver. The only thing the new received will recognize are the transmitters that came with the new kit.
CAN I use the old transmitters with the new receiver I just got or will that not work?
I would like all my transmitters to work the same way - A and B operates the 202U receiver I installed last year in Application 1, and the C and D buttons to run the new 202U I just got today in Application 2.
Appreciate any help you can offer.
