I'm trying to connect a Darbee to a URC MRF-260, controlled by a MX-880. Plugging a cable directly into the IR in port doesnt work. I emailed Darbee for help and got the following answer:
"The IR IN on the Darblet expects a pin-out, from tip to sleeve of: (3.3V VCC Out, 3.3V IR In, GND). If an external, powered IR extender is being used, a 3.3V IR signal should thus be present on the ring (middle contact), GND connected on the sleeve, and the tip should be left disconnected (because the Darblet is supplying 3.3V there, expecting an unpowered IR extender)."
they couldn't give me much in terms of follow up support and suggested trying the blaster.
Anyone have any advice?
