DIR22
Digital Micro Infrared Receiver
Installation Instructions v1.0
Warning: To be installed and/or used in
accordance with appropriate electrical codes
and regulations.
Introduction: Thank you for your purchase of a Knoll DIR22
digital infrared receiver. This receiver features a long indoor
usable range and it can be used in direct sunlight and near
plasma and other TV’s. It is designed to act as a remote
receiver of remote control signals that when passed through a
connection module and emitters, relays remote infrared
commands to equipment in a distant room.
Features:
• Very small design,
available in white, silver
and black colors.
• Will relay almost all
remote control types
(except some B & O
models).
• Can be connected with almost any 3-conductor wire
including cat 5.
• Requires very little power. Suggest using PS1202 12 vdc
(200 mA) for up to 5 DIR22’s.
• Requires DIR54, DIR55 or DIR58 connection module,
power supply and emitters to work.
• Up to 10 or more DIR22’s and other compatible models
can be connected in a single system.
• Connects with a three wire connector.

Installation Tips
1. Follow all local electrical & building code requirements.
2. The DIR22 is mounted on the wall, cabinet door frame or other
vertical mount. In order to work it requires a PS1202 (200 mA) or
PS1205 (500 mA) 12 VDC unregulated power supply, IR31 (single) or
IR34 (dual) emitters and one of the following: DIR54 (decora inwall
style, 4 output), DIR55 (tabletop style, 4 output) or DIR58 (wall mount
or SMC style, 8 output) connection block.
3. Wires can be solid or stranded, shielded or unshielded with a
minimum of 28 gauge for runs under 200’, 22 gauge for runs under
500’ and 20 gauge for runs up to 1000’. Wires can be looped from
DIR22 to DIR22 or home run. Home runs generally offer more
reliability and future flexibility.
4. DIR22’s can be mixed and matched in larger systems with up to 10
DIR infrared receivers, such as the Knoll DIR21 or DIR10.
5. When using a DIR connection block, connect the DIR22 +12vdc,
GND and SIG terminals to the corresponding DIR55 or other Knoll
digital connection block terminal. Prepare the wire leads to and from
the DIR receiver by stripping about ¼” of the insulation from each of
the 3 leads.
Twist the strands tightly together so that they do not stick out of the
connector and cause a short-circuit. Be sure to observe polarity.
6. Next plug in the single or dual emitters into the DIR connection
block.
7. Then plug in the PS1202 (for up to five receivers) or PS1205 for five
to eleven receivers.
8. The infrared system is usually left plugged in all the time (to an
unswitched outlet) as it uses very little power.
9. Test the digital infrared system to see if it is working properly. If it
works only from a very close range or it does not work at all, first mark
where the pot adjustment is on the DIR connection block blue color
pot. This is so you can reset it to that starting point again. Try
adjusting the pot on the connection block very slightly left and right as
you are testing the receiver with the remote control. This may require
two people. This should correct for the problem. If it still does not work
properly, please call Knoll Systems and ask for infrared technical
support at 1-800-566-5579. The help line is open from 7:30 AM to
5:00 PM Monday to Friday Pacific time.
