INSTALLATION
This unit is meant to be installed into a standard J-Box mounting box and interfaced to Xantech Connecting Blocks, such as the CB12,
789-44, 791-44, etc.
CAUTION: The J-Box must NOT be shared with 120/240VAC circuits
.
PLACEMENT
Placement of the IR Receiver does matter when used in
the presence of a Plasma Display. Ideally it should be
placed somewhere around the Display with the front of
the receiver flush with the front of (or set back from) the
Display. If the 780-95 needs to be placed in front of the
display (such as on an adjacent side wall perpendicular
to the display), make sure it is placed at a location at
least 45 degrees off axis from the corners of the unit –
see
Figure 2
. The presence of Direct Sunlight and
Fluorescent Lighting should not effect the reception of
this unit.
Note:
Plasma interference can be reflected off of any
item it comes into contact with within approx. 3 feet from
the front of the display. Keeping this in mind, make sure
that the 780-95 is free of any obstruction that might
reflect back into the receiving eye.
Note:
While this unit shows strong rejection to standard
50/60Hz ‘ballasted’ fluorescent lighting, it is still prone to
interference from CFL style Fluorescent lighting.
MOUNTING
1. Pre-wire a 3-conductor cable (refer to
Specifications
section for proper Wire Gauge) from the connecting block location to J-
box mounting location.
Note: If using the STATUS LED feature, use 4-conductor cable in the appropriate gauge (see Figure 5)
2. Connect proper wires to the +12VDC, GND, STATUS (if applicable), and IR OUT terminals on the rear of the 780-95 as shown
in
Figure 3
.
3. Secure the 780-95 into the J-Box using the supplied screws.
