The OP referred to a 9 way 3.5 mm in post nine, likely incorrect terminology or missing some words in his sentence, i.e. 9 pin DB9 to 3.5mm I assume.

My money is on this alone not solving his problem with the 'noise'. One of the systems we had this problem with was IR only and the other did it while serial connections were taken out.

i think he was trying to show a list of connections.  on one side the 3.5mm, on the other side the db9.   the spacing was just messed up on the post.

did you use IR on ports 7-12?  did you use sleeved emitters?

Excellent thought but no. Each had 6 or less IR on ports 1-6. Noise was present with all emitters unplugged, just MSC and RFX attached with STP no where near any gear, lights, speakers, switches and only present during macros and volume ramps.

my wife baked some cookies last night :)



i just metered out a urc male rs232 cable

looking at the photo above from left to right

far left = pin 5
2nd from far left = pin 2
3rd from far left = pin 3
far right/tip = no connection

essentially, by not using the proper connector, you are shorting out your pin 2 to pin 5.  one thing you might be able to try, is to disconnect pin 2.  what is probably happening, is the feedback coming from the projector is shorting out to pin 5, thus causing your noise.  personally, i would just pick up a urc cable and connect to that.

Thanks for this dude. I think we are going to leave it the client thinks its a feature.........

I would say the problem is down tot he cable though.

Yes Duct tape was correct we were using a 9 way D type to a 3.5mm pin audio connector.

are you saying he likes the noise?  I wouldn't leave it like that.  You might end up frying the port on the msc400 or the projector.
