Can I take one of the IR outputs, run it through CAT5, run it into the IR in of a Xantech 791-44 amplified connecting block? It would be useful in multi-room distribution system to be able to control global servers, ipod, DVr, Xm radio, while also controlling the local zone equipment such as a local DVD, AVR, Cable Box, and TV.
If you cannot use the 791-44 could this be achieved using the MRF350 by running CAT5 betwen the IR out of one of the emitters to the IR in on the MRF350? I realize you will not have IR routing, but this would be nice for larger distributed video systems.
Alos how long can you run one of you emitter wires away from the MSC400?

run only the IR and ground to the connecting block. Do not connect the +12v output of the MRF to the connecting block (power it with its own transformer). You may also want to insert a diode to isolate the two from any voltage feedback.

This may cause a ground loop or RF noise pickup. To avoid this and completely isolate the equipment you may need to use an opto-coupler like a 4N33. I've never tried it though and you would need to calculate resitor values so that the opto would be able to run off the 12V bus on the connecting block and that you wouldn't be overdriving the photo diode. Beyond the scope of this discussion.

I do this on nearly installation - always with excellent results. You DO need to power the connecting block on it's own, and as tgrugett said, only hook up the signal and ground. No diode isolation is necessary in this scenario.
I've never had to do what Toddilus is suggesting.

Chasing Ernie's post count, one useless post at a time. |

Ok. That's good then. No optocoupler needed.
