JP1 Remotes

I stumbled across and Atlas 5 Day URC-1055 JP1.3 3033 at the local thrift shop for $4 and since it is based on the S3C80 chip it was pretty easy to create my own protocol that works with the Inkel AD20 after which I subsequently noticed that "The Robman" had already done this. (D'oh) Both the ...

Update:
With the info supplied by 3FG I have been able to create raw IR codes to control the Inkel AD20 amplifier. The following information should work for any remote based on the TC9132P chip.

Timing of each bit is determined by the frequency of the crystal used:

T=timing
XF= crystal frequency ...

Thanks 3FG.
I have a esp8266 set up to transmit and receive IR. ( https://github.com/crankyoldgit/IRremoteESP8266 )
It can send and capture raw signals. With the IRP you have given I should be able to work out what to transmit. Once I have signals that work I can either use the esp8266 to ...

No push/pull. The manual states that the remote (RD50) can control the amplifiers:
Power on/off
Phono/tuner/tape selector
and Volume Up/Down

I'll give the volume controls a try. The 6030R upgrade was a no go.

I also just found the following line from the manual:

"Remote Control Technics 15 Bites ...

I tried all the remote codes that came up for the "inkel" brand which included the NEC2 131.68 and NEC1 131.69 codes. (created an upgrade with just the power button) I'll try the 6030R upgrade just in case. The thing is so old I know it's a long shot. I does make a good IR detector though as every ...
