Installation Tips
1. Follow all local electrical & building code requirements.
2. The DIR10P is usually shelf or tabletop mounted. In order to
work it requires a PS1202 or equivilent 12 VDC unregulated
power supply and a IR31 (single) or IR34 (dual) emitter. A
connection block is not needed.
3. The two conductor emitter wire can be extended up to 1000’.
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’.
4. Simply plug in the single or dual emitter into the 3.5 mm jack
port. If you are going to extend the emitter wire, carefully
observe polarity.
5. Plug in the PS1202 power supply and the DIR10P should be
ready to go.
6. The infrared system is usually left plugged in all the time (to
an unswitched outlet) as it uses very little power.
7. 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
DIR10P blue color pot on the rear of the DIR10P. 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 a.m. to 5:00 p.m. Monday to Friday Pacific time.
