Remote In/Out on Sony TV

[felixrosbergen]

Hi All,

I just found out the 51" Sony Rear project DLP (HD) i have had for 4 years actually has 'remote in/out' connections which appear to be headphone jacks (3.5mm i guess).

Does this mean i can send it IR over hardwire or does this still use some sort of proprietary control protocol??

If i can send the TV IR com,amd directly via wire this open up some good possiblities. I assume the remote out woudl then forward whatever IR the TV receiver to what is connected to that port.

Is there stanard wiring for headphon jacks relate to IR. The few IR blasters i've seen have had what appears to be 2 connections (tip and 1 sleeve) but i recall reading somewhere that hardwired IR is 3 wires...is that simply become you have a common and 1 signal wire to send and anther one to receive?

When connecting additional zones to the USB-UIRT are these blasters only? I recal reading that USB-UIRT have 3 zones, but there is only 1 jack. Does this mean a need a plug with 2 'sleeves' and each sleeve is a zone?

Most IR jacks are just mono headphone jacks however some are smaller still. The USBUIRT has a stereo headphone jack on the back of it, the right channel is one zone, the left channel another and the front emitter is the third. You call these zones by adding a z1, z2 or z3 to the front of your IR codes. Radio shack sells stereo to mono splitter that DOES NOT combine the signals, otherwise you can simply solder the plug yourself.

I would assume the Sony TV to recieve all it's normal code via that rear port, I dunno about it passing on non-Sony codes though. I can totally see Sony being like that.


Also someone does sell a premade emitter with stereo jack and each emitter is it's own zone but I can't recall much about it, the leads are ver short so it only works well for cable/sat box control.

Collin...it seems you are correct that the Sony TV only passes Sony code through..i plugged a blaster, put the blaster on the SageTV HD extender..aimed the sage remote to the TV......nothing...unfortunately i don't have another sony product to confirm my suspicion...

The Sony manual says it passes Sony equipment code 'and some others'....
