Not an expert user, but have been using for years. I have a small setup in my home. The C15A is sending wrong codes to some modules. I replaced the modules, checked the batteries in the C15A, The module I am trouble shooting, works fine with the portable HR12A. I see the codes - below. But when I send (tap the AHP module) it sends the wrong code. (see codes below). Other modules work ok from C15A. Befuddled. Can anyone help.
Now while I was checking the codes for the background to my trouble I noticed that the AHP was sending extended codes for the ON but normal codes for OFF. In other words with the HR12A I can turn it on - A2 ON. and the AHP sends an A2 OFF and the module responds. BUT the ON command from the AHP sends an Extended code - see below.
Still mystified.
AHP ON Code - Send Extended Code 3e 31 (this does not turn on the lamp)
AHP OFF Code -Send Address A2 (this works if the lamp is on)
Send Off (A2)
HR12A ON Code - P Receive RF A2 ON
P Receive Address (A2)
