APPLICATION WIRING

A typical system, with a 490-85, 781RG Power Supply and 283M Emitters plugged into a 791-44
Connecting Block, is shown in the figure below.

1. Plug the 3.5 mm stereo mini plug from the 490-85 into the 791-44 connecting block labeled “IR

RCVR”.

2. Plug in the 3.5 mm mono mini plug from any of the 282, 284, 283 and 286 series Emitters into

the jacks labeled EMITTERS on the 791-44 Connecting Block and affix the opposite end of the
IR Sensor Window of the controlled equipment.

3. Plug in the 2.1mm Coaxial power plug of the 781RG Power Supply (not included) into the jack

labeled 12VDC on the 791-44 Connecting Block.

4. Plug the AC end of the 781RG Power Supply into an ‘un-switched’ 120VAC outlet.
