Crazy Marantz remote
Posted: Thu Nov 10, 2022 3:51 pm
I have a Marantz RC040SR remote control I have repaired, but is still struggling so I have created my own remote control. My remote controls an LG TV as well as the Marantz A/V receiver. I have the LG TV (NEC IR) working just fine as well as the 'simple' Marantz functions, but the Marantz has some 'extended' codes on the remote AND some extended codes that are NOT on the remote. This is where I am running into some issues.
The Marantz simple codes are for sure RC5 and the extended codes are RC5X or RC5 Extended or RC5 Marantz code. Using AnalysIR I can see the RC5x code, but it is not interpreted properly (from what I can tell). AanlysIR shows both codes as RC5, but the RC5x code extension (after the 4496us space) is not decoded. The Reverse Engineering Tool shows RC5 as 14-bit which is correct and the RC5x as 9-bits which is true for the code before the space.
Here are the two traces:
RC5X: RC5: Has anyone seen this code before?
