The Philips RC6 IR Remote Control ProtocolAuthor

PAGE 2 of 2 - Scanning the output of an RC6 compatible Philips remote control


I happen to have a Philips remote control for my DVD player which operates with the RC6 protocol. With the proper triggering settings on my oscilloscope, i managed to capture two sequential transmissions from the remote control to measure the interval between them. To capture the IR signal, i connected the oscilloscope's channel to the output of a TSOP 1838 IR receiver.


I connected the oscilloscope's probe to the output of the TSOP I captured two transmission cycles and i measured the interval: 83mSec



Afterwards, i changed the time/div to "zoom" into one transmission signal. This way i measured the time required for a complete transmission to finish: 23.1 mSec.


 
 



I also took two sequential snapshots after pressing button "1" twice, to demonstrate how the toggle bit works:

Toggle bit = 1 Toggle bit = 0




As for the carrier frequency...
With the same configuration that i used to detect the RC5 carrier frequency, i detected the carrier frequency of the RC6 protocol as well:


 
 



The carrier frequency is 36 KHz, similar to the RC5 protocol.

    • @Shahzad and @sanghvi,
      Apparently robots like remote control stuff!

    • Some information about RC6 can be found from patent document: http://www.freepatentsonline.com/5877702.pdf in which there is also a reference to Philips IC SAA3028.
