This is an older system that used to have Pronto 6000's and RFX extenders flashing IR through an emitter affixed onto Elan Z035 IR tubes wired into Elan HD system zone cards for source and volume control. The Prontos are dying and I decided to replace them with the URC remotes. Here is the problem: the Elan system will not respond to the IR codes flashed through the MX-980/MRF-260/Z035 combo. However, when aiming the MX980 in IR mode at the Z035 the Elan system responds as expected. It would seem that the MRF-260 is not translating the elan codes well. Has anyone overcome a similar issue and if so what was the fix?. I have tried all combinations of emitters and have tried adjusting the IR outputs of the MRF-260. Ir codes flashed through to the source devices work as expected.
