APPLICATION WIRING 
A typical system, with a 490-95, 781RG Power Supply and 283M Emitter plugged into a 789-44 Connecting Block, is 
shown in Figure 3:
1.  Plug in the 2.1mm Coaxial power plug of the 781RG Power Supply (not included) into the jack labeled 12VDC on 
the 789-44 Connecting Block. 
2.  Plug the AC end of the 781RG power Supply into an ‘un-switched’ 120v AC Line outlet. 
3.  Plug the 3.5mm stereo mini plug from the 490-95 into the IR RCVR input on the 789-44 Connecting Block 
4.  Plug in the Emitters 3.5mm mono mini plug such as any of the 282, 284, 283 and 286 series into the jacks labeled 
EMITTERS on the 789-44 and affix the opposite end to the IR Sensor Window of the controlled equipment.

ADVANCED WIRING CONFIGURATION 
490-95 may also be used where the 7-foot lead is not long enough. In this case, simply use the CB12 Connecting Block 
as a “break-out” block. In Figure 4, a 490-95 is extended down to a 789-44 Connecting Block and combined with other 
Xantech IR Receivers. 
1.  Plug the 3.5mm stereo mini plug from the 490-95 into the IR RCVR input on the CB12 Connecting Block. 
2.  Using 3-Conductor wire (refer to Specifications section for proper Wire Gauge) connect the terminals labeled V
G S of the CB12 to the terminals labeled +12VDC, GND, and IR IN on the 789-44 Connecting Block (or other) 
3.  Plug in the 2.1mm Coaxial power plug of the 781RG (or 782) Power Supply (not included) into the jack labeled 
PWR on the 789-44CB. 
CAUTION! Do not
 plug in a 781RG or any other Power Supply into the CB12 when using in a “break-out” 
configuration. This will put 2 supplies in parallel and possibly damage your equipment. If a ‘local’ emitter is needed on 
the CB12, see Step 5 below. 
4.  Plug in the Emitters 3.5mm mono mini plug such as any of the 282, 284, 283 and 286 series into the Emitter 
Outputs on the 789-44.
