IR Over Narrow Band via Optional RFX-250
Note: RF remotes via RFX-250 can only control IR components.
RS232, Relay and Sensor control are not available to RF remotes.
1. Power on all AV components, lower all dimmers to 50% and
power on anything that may create RF Interference (particularly
devices with high speed microprocessors or hard drives).
2. Check that the address wheel on the back of the MRX-1 is set to
ID#0 (the interference “sniffing” position). If it is not, use the
included small flat blade screwdriver to set the RF ID# to 0.
3. Connect the MRX-1 to its DC wall adapter and plug the wall
adapter into a live AC outlet. Place the MRX-1 in a convenient
central location in the equipment rack. Unlike an MRF-250, the
MRX-1 can be placed next to components with hard drives or
high speed microprocessors. There is no RF circuitry inside the
MRX-1 itself.
4. Connect the RFX-250 to the MRX-1’s RF INPUT jack as shown.

When connecting a single RFX-250 to the MRX-1 utilize the cable with 3.5
mm plugs on both ends. When you need a longer wire or are connecting
up to three RFX-250s, use a cable with tinned ends or splice it. Cable can
be extended as much as 200’, then connected to the spliced end of a
3.5mm cable.
