Optimizing Narrow Band Reception
with the MRF-300 or MSC-400

RFX-250 INSTALLATION MANUAL
Overview - Compatibility
The RFX-250 is a narrow band RF receiver. It replaces an RFX-150 receiv-
er in either an MRF-300 or MSC-400 system. It is tuned to receive a much
narrower band and is more immune to the interference found near com-
ponent racks (generated by microprocessors and power supplies). It is
NOT compatible with all URC remote controls.
Connections
NOTE: The RFX-250 is ONLY compatible with the current versions of the
MX-3000, MX-950, MX-900 and the TX-1000 remote controls. The RFX-
250 is NOT compatible with MX-3000 remote controls manufactured
before April 1, 2005.
You can identify the build date of an MX-3000 by looking at the serial
number. The first 6 digits indicate the build date. If the serial number
appears as 122905 014054, the first 6 digits indicate that the remote was
built on December 29, 2005.
When the RFX-250 can be placed within 10 feet
of the MRF/MSC unit, you can utilize the cable
with 3.5 mm plugs on both ends. When you
need a longer wire or are connecting up to
three RFX-250’s, use a cable with a minimum of
three conductors. If you use CAT 5, utilize two
conductors each from two of the twisted pairs
for DATA and two from the other twisted pairs
for 5V. Use all four of the other conductors
twisted in with each pair for GND.This provides
better shielding and conductivity for long runs.
Connect ONE (only)
of either of the RFX-
250’s RF OUT connec-
tors to ONE (only) of
either of the RF IN
connectors on the
MRF or the MSC.
Once the RFX-250 is correctly connect-
ed, the POWER LED lights.
If the RF LED lights, the RFX-250 must
be moved to a new mounting location. It
is receiving in-band RF INTERFERENCE.

Optimizing Range and Reliability
1. Power on all AV components, dim all dimmers to 50% and power on
anything that may create RF (particularly devices with high speed
microprocessors or hard drives). Observe the RF LED of the RFX-250 by
cupping your hand over it. If it is glowing or flickering you must relo-
cate the RFX-250. If you cannot relocate the RFX-250,
try removing its antenna.
2. Once you have found a location that is absolutely clean
with everything on, test to see if the range is adequate
and that macro reliability is perfect. Start with the
antenna angle set to 45 degrees and positioned so that
the long side of the antenna is facing the customer’s
favorite seating position.
3. When testing, set both the remote and the MRF/MSC to the same
VALID RFID#. Keep in mind that zero (0) is not a valid RFID#. Watch
the STATUS LED on MRF/MSC - it should light every time you press a
button on the remote. This will tell you that the signal was received
and understood. Ignore the RF LED on the RFX-250 (it only indicates
that a signal was received, not that it was understood).
4. If the range is inadequate, you may extend wire to any area that is not
giving good results and place an additional RFX-250 in that area. Up to
three RFX-250’s can be connected to each MRF/MSC.
NOTE: The RFX-250 is ONLY compatible with additional RFX-250s. You
cannot mix RFX-150s in a system with RFX-250s.
