Hi everyone,

I just bought a Pioneer VSX-1021 receiver and would like to use it with my Harmony 890 remote but without the IR blasters.

Instead I would like to use the IR in & out sockets on the back of the receiver and on the back of my Oppo BDP-83 to have something like this :

Harmony RF Extender IR out ---> VSX-1021 IR in / VSX IR out ---> Oppo IR in.

I would like to know what kind of cables to use between the RF extender and the VSX, and between the VSX and the Oppo. Is it Mono-Mono, Mono-Stereo or Stereo-Stereo jack cables?

Thanks for your help.

Search Google for wired IR connection to AV receiver. You will get lots of info, diagrams, etc.

Search for this post on avsforum,

"The IR jacks on the -93 are different than the -83. The -83 has a 3-wire with a hot tip and requires a "stereo to mono" adapter cable to interface with most IR distributions systems. The -93 has a standard mono jack with no power and does not need the adapter cable.

The -93's front sensor is disabled when you use the jack, the -83's is not."

Sorry I lost the link in my cut/paste process, but you should be able to find it.
Thanks for your support.

Thanks a lot Mediadogg.

I had a responses from both Oppo and Logitech :

Quote:

For the HM-31 and the DV-983H we are using a 3.5mm head which includes a tip, ring, and sleeve (<=||=||=|). The tip is a 5v signal, the Ring is the IR signal, and the sleeve is the ground. Most standard 3.5mm cables are just the tip and the sleeve (<=||=|). With a standard 3.5mm cable the ground signal is not present, which prevents the signal from being processed correctly. You will need a 3.5mm cable at at one end has the tip, ring and sleeve and at the other end has the tip and sleeve only.

We can supply a 1m cable for $2.00 shipped.

Best Regards,

I understand that you want to know the size of cable you need to use. I am going to do my best to help you.

Although we don't support the direct connection of the RF extender to the device you can do this with a Mono 1/8" cable

Regards,

Davy
Logitech Customer Care


So for the BDP-83 I need a special cable but for everything else it's mono to mono 1/8" jack.

Funny, I read the Oppo email exactly the opposite. They say the DV-983H has a stereo jack. If you plug in a mono to mono cable, The DV-983H will not see the IR signal coming in, and its +5V will be sent backwards to the sending device. Did I misunderstand it?

If I were you, I would spring for the $2.

You're right about the DV-983H. In another e-mail, they told me that the IR in & out of the DV-983H is the same in the BDP-83. So they both need a special stereo-mono cable to get/send proper IR signal.

But for other devices (including the BDP-93), it's usually mono-mono.


And the 2$ is already in Oppo's pocket
