Page 2RFX-250i INSTALLATION MANUALPage 1RFX-250i INSTALLATION MANUALOverview - CompatibilityThe RFX-250i is a 433MHz RF receiver. It connects to an MRF-350,MRF-350i, MSC-400 or an MSC-400i. It is not compatible with allURC remote controls. It is only compatible with “I” series remotecontrols, which transmit at 433MHz.ConnectionsOptimizing Range and Reliability1. Power on all AV components, dim all dimmers to 50% and power onanything that may create RF (particularly devices with high speedmicroprocessors or hard drives). Observe the RF LED of the RFX-250i bycupping your hand over it. If it is glowing or flickering you must relo-cate the RFX-250i. If you cannot relocate the RFX-250i,try removing its antenna.2. Once you have found a location that is absolutely cleanwith everything on, test to see if the range is adequateand that macro reliability is perfect. Start with theantenna angle set to 45 degrees and positioned so thatthe long side of the antenna is facing the customer’sfavorite seating position.3. When testing, set both the remote and the MRF/MSC to the sameVALID RFID#. Keep in mind that zero (0) is not a valid RFID#. Watchthe STATUS LED on MRF/MSC - it should light every time you press abutton on the remote. This will tell you that the signal was receivedand understood. Ignore the RF LED on the RFX-250i (it only indicatesthat a signal was received, not that it was understood).4. If the range is inadequate, you may extend wire to any area that is notgiving good results and place an additional RFX-250i in that area. Up tothree RFX-250i’s can be connected to each MRF/MSC.NOTE: The RFX-250i is ONLY compatible with additional RFX-250is. Youcannot mix RFX-250is in a system with RFX-250is.When the RFX-250i can be placed within 10 feetof the MRF/MSC unit, you can utilize the cablewith 3.5 mm plugs on both ends. When youneed a longer wire or are connecting up tothree RFX-250i’s, use a cable with a minimum ofthree conductors. If you use CAT 5, utilize twoconductors each from two of the twisted pairsfor DATA and two from the other twisted pairsfor 5V. Use all four of the other conductorstwisted in with each pair for GND.This providesbetter shielding and conductivity for long runs.Connect ONE (only) of either of the RFX-250i’s RF OUT connec-tors to ONE (only) ofeither of the RF INconnectors on the MRF or the MSC.Once the RFX-250i is correctly connect-ed, the POWER LED lights.If the RF LED lights, the RFX-250i mustbe moved to a new mounting location.
