I had a cut wire and had to replace the IR Eye wire with a headphone cable. The IR puck has 5 connections and the headphone jack has three wires (green/ground, red/right, white/left). Does anyone know what wire goes to what three connections on the IR Eye? Thanks.

I have two different looking IR eyes, both with five terminals. One has the lettering intact and the second is missing letters. The one with missing letters has three wires - green on 3, yellow on 4, and brown on 5.

So, it looks like from the drawing it should have been wired yellow to 1, green to 3, and brown to 5, correct? Can both of these be connected to use all 5 of their terminals when connected to the BeoSystem 3? What functionality would this provide? Which terminals on the IR eye go to which on the DB9 plug labeled IR-In?

Sorry for all the questions. But I’m trying to start up my BeoSystem 3 I bought from my local dealer, and l’m not sure if I have all the pieces. Thanks.

If you look at page 6.11 of the BS3 service manual you will see the pinout of the 9 pin IR connector.

If you just want to use IR control, then I think just 5V, IR and Ground need to be connected.

Guy, thanks as always. I have the pin out from the service manual, but there are 9 pins and 5 terminals. If I terminate the three as you mention, I will have IR control, but that’s the same as the 3.5mm input. What will happen if I use two additional wires? And which wires would I use? Is it just 3 wire IR control or 7 wire (with Autocontrast) connections with the BeoSystem 3 or is there a 5 wire option?

In the 9-pin connector.

I think you can ignore Pins 1 and 2, as they relate to BtB (Hotel version control)

Pins 4 and 9 relate to light sense - but the BS3 manual states that they are not used (at least when the manual was produced).

Pins 3, 7 and 8 give IR control as already discussed.

This leaves pins 5 and 6, PT led and S.B led.

I would hazard a guess that these relate to 'Play Timer'(Green LED?) and 'Standby'(red LED?) respectively, hence connecting to the remaining two terminals on the puck would display these LED indications, if the IR eye has these.  You could check whether the IR eye lights up in this manner by applying a small voltage (2-3V) to each terminal in turn (-ve to ground, obviously).
