Just posted in the live file section a "V0.9" of my upgrades as I think it's good enough if anyone needs it - as stated before comments welcome

Update:. I am starting to suspect that the CD control is just a pass through from the IR receiver but sadly my genius idea of hooking it to the IR in jack of an Oppo BDP-95 did not work. Don't know if I need an amplifier or something in line to make this work.

You're probably right, many stereo systems have pass thru wires that connect the components, assuming they're all the same brand and type, where the audio receiver is the only one that receives the remote signals and it passes on the commands to the other components. I know I had a Kenwood system like this once, and Sony does the same.

The IR in jack on the Oppo is wired in a somewhat non-standard fashion. It is all to be found in the documentation.

Can you elaborate please? I do not know what the standard fashion is, nor do I have the Oppo service manual, although there is some detail on it in the owner's manual. I do have the TP-117 schematic which is nice. I did put a voltmeter on the cable while sending a remote signal to the TP-117; even though the light didn't come on on the TP-117 when sending Oppo codes (the standby light blinks when it receives a Luxman code), I did get a voltage swing on the cable, probably about 0.9V or so. I didn't put a scope on it but I can if that would tell me anything.

It would be truly amazing if I could get the Oppo working through the TP-117's cable because then I'd have my best media player hooked to my best preamp and actually working together in a way that I could use the Zone 2 output transparently. Of course I could also get one of the Luxman RC-503 IR repeaters (which probably haven't been made since 1991ish) and that would work as well (I assume; - HiFiEngine doesn't appear to have the installation sheet for those accessories), but it would be better to make it work with stuff I have on hand of course, and without having to find a place for an IR emitter.

Well, I know that the *tape* controls on the Luxman are pretty rudimentary. Basically the controls all are in the preamp or receiver and they just send a voltage on a wire of a multi-pin cable. If anyone is following this and needs details on how to make that cable, post #16 here details that... it's basically a 8 pin mini DIN cable with one end cut off and a 8 pin DIN 262 degree plug soldered on.

However I suspect that the CD control is in fact just a pass through of the IR signal, and I don't see why it wouldn't work for other devices as well if I can puzzle out how to make it work, although I'm not sure that I actually have any devices besides the Oppo 95 and a 103 that have a similar connection.

Sorry, I must have confused it to the Oppo 83/85, which has a TSR (Tip-Sleve-Ring) 3.5mm jack. The 93/95 has a TS jack, sleve ground, tip signal (manual page 21). IIRC. I have been controlling mine with a GlobalCache GC-100 connected to the IR in jack, so it is not non-standard after all. Sorry for the confusion.

No worries at all, but I seem to be unable to make it work in any case. I'm going to have to look into an accessory IR blaster for the TP-117 I guess. Hopefully *that* output is not non-standard (despite having an F-connector not a 3.5mm) unfortunately I don't have any laying around to play with so this will have to wait.
