MRF-350 BASE STATION
Page 1
1. MSC System remote controls send
radio waves in every direction, so
your client enjoys “No More Pointing”
operation!
Introduction
The MRF-350 base station is an “addressable” base station like the MRF-300.
RF Addressing gives you the ability to control as many as 90 identical components throughout a house. However, the MRF-350 is equipped with the
Narrow Band RF reception, so is only compatible with MSC System remotes.
2. The RFX-250 RF Sensor can be freely positioned out of way of
the interference the A/V components create, connecting to the
MRF-350 via a 10’ cable (which can be extended).
3. The MRF-350’s built-in Front Blaster sends commands to
components in the same cabinet space as the MRF-350.

Features and Benefits
Interference Rejection and Extended RF Range via RFX-250
The MRF-350 receives RF (radio frequency) signals via the RFX-250 RF Sensor.
The RFX-250 displays RF interference via a bright red LED, which flickers when
interference is present. Simply relocate the RFX-250 out of the interference.
Expand Range by Adding RFX-250 RF Sensors in Remote Areas
The MRF-350 can power up to three RFX-250 RF Sensors connected in parallel
to the RF Input connector.
Variable IR Output Matches Rear Panel IR Inputs
The MRF-350 is equipped with adjustable IR line outputs, each output can be individually matched to rear panel IR inputs on any component that is designed to be
operated by a standard IR repeater. The outputs utilize a 3.5mm jack.
Up To Fifteen Equipment Locations With Identical Components
Each MSC System remote is “addressable.” They can be programmed to specifically control components in a particular room by installing a base station at each
location. In operation it’s simple: when you select a device located in the Den,
the MX series remote only sends commands to the Den. When you select a
device located in the Family Room, the MX-3000 only sends commands to it.
A Single MRF-350 Can Control an Array of Identical Components
or Identical Zones of a Multi Zone Preamp/Matrix Switcher
Each MRF-350 has six “addressable” IR Line Outputs. For example, you can control up to six identical TV’s with one MRF-350 or route volume commands for a
specific zone to a particular zone IR input on a multi-zone preamp. If you have
more than six identical components or zones, up to 15 additional MRF-350s can
be installed to control them (thus allowing up to 90 identical components or
zones in one house).
IR Input for Keypads or IR Repeater Systems
The MRF-350 rear panel IR input will relay IR Data from IR repeaters or MultiZone Keypads to all IR line outputs (does not support IR routing). The 5V, 100
milliamp output will directly power some brands and models of keypad directly.

Optimizing Range and Reliability
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 bottom of the MRF-350 is set to
ID#0 (the interference “sniffing” position).
3. Connect the MRF-350 to its DC wall adapter and plug the wall adapter
into a live AC outlet. Place the MRF-350 in a convenient central location in the equipment rack. Unlike an MRF-250, the MRF-350 can be
placed next to components with hard drives or high speed microprocessors. There is no RF circuitry inside the MRF-350 itself.
4. Connect the RFX-250 to the MRF-350’s RF INPUT. You can connect to
either the screw connector or the jack as shown:
Slide off the mounting plate to reveal the RF ID# rotary switch. Check that the arrow
pointer in the center of the wheel is pointed to 0, the default “interence sniffing” position. If it is not, use a small flat blade screwdriver (included) to set the RF ID# to 0.
When connecting a single RFX-250 to the MRF-350
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.
Cable can be extended as much as 200’, then connected to the removable screw connector plugs. If
you use CAT 5 connect four conductors to GND
(one from each twisted pair) and connect the remaining conductors two at a time to 5V and DATA .
