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 compo-
nents 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 indi-
vidually 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 specifi-
cally 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 con-
trol 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 Multi-
Zone 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 loca-
tion in the equipment rack. Unlike an MRF-250, the MRF-350 can be
placed next to components with hard drives or high speed micro-
processors. 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” posi-
tion. 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 con-
nected to the removable screw connector plugs. If
you use CAT 5 connect four conductors to GND
(one from each twisted pair) and connect the remain-
ing conductors two at a time to 5V and DATA .

5. Observe the RF LED of the RFX-250. Cup your hand over the RFX-250’s
RF LED. If it is glowing or flickering you must relocate the RFX-250 to a
location where the LED doesn’t flicker.
6. Observe the STATUS LED of the MRF-350. It is a little more sensitive
than the RFX-250. If you see any flickering of this LED, move the RFX-
250 to a new location.
If your installation location simply doesn’t offer you any choice and
you are detecting interference everywhere you place the RFX-250 you
have three last resort options:
a. Remove the RFX-250’s antenna. This will reduce the range
enormously, but may still be enough for this client.
b. Extend a wire to another room. Try this over the floor first,
before attempting to conceal the wire.
c. Admit defeat and install a “pointing again” IR repeater system.
If no buttons are pressed on any
remote control, no valid RF transmis-
sions are being received. The flickering
or glowing RF LED warns you that the
RFX-250 is detecting RF interference
generated or reflected near this
location. MOVE the RFX-250 to a new
location.
The flickering or glowing STATUS LED warns you that the RFX-250 is detecting RF
interference generated or reflected near this location. MOVE the RFX-250 to a new
location.

7. 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 posi-
tioned so that the long side of the antenna is facing the
customer’s favorite seating position.
When testing, set both the remote and the MRF-350 to
the same VALID RF ID#. Keep in mind that zero (0) is not a valid RF
ID#. Watch the STATUS LED on MRF-350 - it should light every time
you press a button on the remote. This will tell you that the signal was
received and understood. You can ignore the RF LED on the RFX-250 (it
only indicates that a signal was received, not that it was understood).
8. If the range is inadequate,
you may extend wire to any
area that is not giving good
results and place an addi-
tional RFX-250 in that area.
Up to three RFX-250s can be
connected to one MRF-350.
9. Should you need more than six
IR Outputs, connect as many as
three different MRF-350s to one
RFX-250 in a daisy chain using
the supplied cable.
To preserve addressibility, set
each MRF-350 to a different RF
ID number. Remember “0”
(zero) is not a valid RF ID.

Connecting IR and Setting Output Levels
1. Connect an IR emitter to each IR output and run the emitter wire to the
front panel of each component. DO NOT STICK the emitter in place.
ADJUST the level first.
2. Adjust each of the IR Output levels for best operation. If the component
operates best at minimum level, but is still operating sluggishly or intermit-
tently, move the emitter farther away from the components IR sensor.
NOTE: TiVo, Replay TV, Satellite Receivers and Cable Boxes are all extremely
sensitive to IR overload or saturation. Put up the on screen guide and test the
navigation arrows. Compare operation via RF to the original remote control.
Operation should be identical. RF is not slower. If operation is inconsistent or
sluggish, LOWER the IR line output.
If you still have sluggish operation, check that the remote control is set to a
particular LINE OUT, rather than ALL. When IR commands are sent to all the
flashers in a cabinet, you can have difficulty adjusting the IR Output.
Reprogram the remote control to send IR commands only via a specific (1-6)
Line Output, then readjust the IR Line Output level.

When connecting to a components rear panel
IR Input, cut the flasher off of the wire, strip the
two conductors and connect to the rear panel
IR Input. The MRF-350 is only compatible with
standard IR Inputs, not proprietary control sys-
tems offered by some manufacturers.

Front Blaster Overload
A few models of audio/video components can be OVERLOADED by the Front
Blaster. If you are having intermittent or inconsistent results with a particular
component, try repositioning the MRF-350 and facing the Front Blaster in a
different direction. If this improves the situation but is impractical, it may be
necessary to utilize the self-adhesive flashers only and follow the steps below
to Disable the Front Blaster. This will limit the number of components your
MRF-350 can control to six. If you have more than six components you can
purchase an additional MRF-350.
Disabling the Front Blaster - Step by Step via PC
