Features and Benefits
The PAR4 offers a number of improvements over other IR routers:
• Universal system – compatible with virtually all brands of A/V
equipment and remote controls
• Routes IR commands to four components
• Simple plug and play operation
• No programming – simply select the route needed from an exist-
ing list of IR commands
• Expandable – cascade two units together to create eight routes
• Printed circuit board design assures high reliability
• Low profile and small footprint with integrated mounting wings
that allow for both horizontal and vertical installation
• UL listed regulated in-line power supply with universal voltage
capability
• Two year parts and labor warranty

Installation Considerations
Placement of the PAR4
Place the PAR4 conveniently close to the main system unit it
will connect to. Generally, the PAR4 is placed in a concealed
location because its indicator lights are only used during instal-
lation. Placement possibilities include:
1. Table-top (on the floor or shelf behind the equipment)
(Figure 2).
2. Wall-mount (affixed to the back of the equipment cabinet
or a nearby wall) (Figure 3).

Installation Considerations (continued)
Before you begin, make sure that the flasher cables and the 12VDC power supply cable will
all reach the proposed location of the PAR4. Mark the cables with labels describing where
the cable originates (i.e. TV1) rather than which terminal on the PAR4 it should connect.
STEP
DESCRIPTION
1. Connect and test the
power supply.
A) Plug the supplied 12VDC power supply into an unswitched
100-240V AC outlet.
B) Plug the connector into the socket labeled “power” on the
PAR4.
C) If the power LED on the PAR4 does not light, test the
unswitched AC outlet with another appliance. If the outlet tests
OK, you have a defective power supply which must be replaced
before you continue. If the red power LED illuminates unplug
the connector from the power socket and proceed.
2. Plug the flashers (not sup-
plied) into the flasher outputs.
See figure 4.
A) Recommended flashers are Niles MF1 or MF1VF MicroFlashers.
If you need to extend the wire, use 2 conductor, 16 gauge
stranded wire.
B) When extending the flasher wire be sure to observe proper polarity.
C) The wire marked with the grey stripe is positive (+); the unmarked
lead is negative (-).
3. Connect the PAR4 to the
IR main system unit using
a 3.5mm mono cable of
appropriate length.
A) Plug one end of the cable into the IR output of the main system
unit (a flasher output on any Niles MSU).
B) The other end of the cable is plugged into the jack labeled “IR
Input” on the PAR4.
See figure 1.
C) During normal operation the blue IR indication LED will flicker
when the PAR4 is receiving IR data from the output device.

BE SURE TO OBSERVE PROPER
POLARITY WHEN EXTENDING
THE FLASHER WIRE.
IMPORTANT
Make all final
connections to the
router before
connecting the
power supply.
The wire lead marked with a
gray stripe is positive (+); the
unmarked lead is negative (-).
This will avoid
potential damage
to components.
Figure 4
Operation
Operating the PAR4 is a simple matter of selecting the appro-
priate IR codes you need from a table of supplied code sets.
See figure 5. The IR codes are available for download from the
Niles Technical Support website:
1. On the Niles Technical Support website select the brand
of remote control you will use to control the PAR4 (i.e.
the Niles IntelliControl) and download the file for that
remote control. After downloading the file you will need to
import it into the programming software for the selected
remote control.
2. From the supplied table select the route you wish to
use (i.e. code 1: all four routes on) and load it into the
remote control.
3. Test the code by operating the remote and observing the
flasher LEDs on the PAR4. For example, if the “all on” com-
mand is issued, all four LEDs should illuminate indicating
that all four routes are active.

Using Two PAR4 Routers
You may daisy chain two PAR4 IR routers together to provide
routing for up to eight identical devices. This is accomplished
by connecting two PAR4 routers together using a mono
3.5mm cable (not supplied). See figure 6. On PAR4 “B” the
3.5mm cable is plugged into the “IR cascade out” jack. On
PAR4 “A” the 3.5mm cable is plugged into the jack labeled “IR
input”.
Operation for two units is similar to operating a single PAR4
with the exception that a separate table of IR routing codes
(table A and table B) exists for PAR4 (A) and PAR4 (B).
Note: When two PAR4 IR Routers are daisy chained
together codes from table A will not operate PAR4
unit B and vice versa.
