ADVANCED WIRING CONFIGURATION
291-95 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 291-95 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 291-95 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 789-44 Connecting Block.
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.

5. If a local Emitter is needed on the CB12, you will need to place a 470 Ohm Resistor in Series with the Signal
Output on the CB12. To wire in this fashion:
a. Cut a standard Mouse Emitter (282M or 283M) approximately 12 inches from the 3.5mm Mono Mini Jack.
You will now have 2 cables; one with a 3.5mm Mono Mini Jack and one with the Mouse Emitter.
b. Wire the 2 leads of the Mono Mini Jack side to a terminal Strip.
c. On the Terminal Strip, opposite the lead with the White Stripe (Signal) connect one side of the 470 Ohm
Resistor.
d. Wire the other side of the resistor to the lead with the White Stripe on the Mouse Emitter.
e. Connect the Black Wire of the Mouse Emitter to the Terminal Strip opposite the Black Wire (GND) from
the 3.5mm Mono Mini Jack.
This will keep the proper load balance and prevent miscommunication with the Emitters on the 789-44 Connecting
Block.
3.5MM MINI PLUG PINOUT
There might be times when the 291-95 needs to be wired directly to a Terminal Block. In that case you will need to cut off
the 3.5mm jack and wire according to
Table 1
.
