THE RIGHT WAY
Look up application note 030042 on netstreams website...it shows how to install an IRlinx with the keylinx for this issue

THE COOL WAY (CURIOUS IF IT WORKS)
Double check with Netstreams tech support (one of the best I've had to talk to)...the XP8 can be connected to a controllinx to accomplish this...not sure if it is an RP6...

THE CUSTOM INSTALLERS WAY - RIGGING
We had similar issues controlling thier panorama matrix switchers, but with enough adjusting of the RF antenna (to eliminate interferance) and the emmiter levels, they now work rock solid. Don't forget, if you have any DVR's in the rack or a media server, the hard drive will interfere with the RF...we moved 4 EVRs and an Escient to the bottom rack spaces and always mount the antenna at the top, yet if I set my laptop on the rack while programming, the whole system freezes.
