Upfront - thanks for the interest and input for this project.
News: The standard IR decoding circuit doesn't detect / read the remote (not surprising). I did check that the circuit worked with another remote - an LG TV.
So the next thing was to dig up the 'scope:
From this, the measured frequency of the carrier is 38kHz (as expected)
The pulse shown is 100110 - which from the "1" button (if I remember correctly). It looks like each pulse is sent word is sent multiple times -- but from reading the manual, it appears that the device only responds to one pulse regardless of how long you hold the button. The device then "beeps" to say it is read for the next input.
I need to investigate that more, but it looks like I can now capture the words/bits for the remote and then build upon the code here to make a custom remote.
More updates to follow.
Cheers
