Good evening party people,

I'm messing with a semi-broken Sony TC-WR87ES which is a 2 head dual well deck. I'm not finding a complete code set for this anywhere so I'm back at it again brute forcing this. Appears that Deck A is device 16 and Deck B is device 14. Of course the codes are not the same deck to deck so I'm doing both. My question is this: how many OBCs are there per device? 0-63? 0-127? How would I tell? or just start punching stuff into the upgrade and see what happens? thanks much!

There are 128 OBCs (0-127) per device code with the Sony protocol. I was going to say to check our Sony site, but I can tell that you did that from the codes listed in your upgrade. It looks like you found 3 new OBCs, so I have added them to the Sony cassette page.

thanks Rob

I was just wondering if there was some way I should know that without trial and error

yes I did fin the list, I was hoping that I'd find more functionality e.g. I didn't find a code for "Blank Skip" or any of the dubbing functions and those are all soft buttons, but maybe Sony just didn't have that functionality. I did find enough to make things work though.

Well, normally you would have the OEM remote to learn them from. Some OEMs do publish their codes, like Yamaha, but that is by far the exception rather than the norm. And even if you do have the OEM remote, there are often other codes, like discrete codes, that can only be found by experimentation.
