5.0 Housing
The receiver is housed in an IP67 rated enclosure, which is dust and moisture resistant. It can be mounted outdoors on
fences, buildings, etc.
NOTE: When installing the lid, care must be taken to insure the gasket fits properly in the correct slot. Failure to do this,
will allow water to enter the box.

6.0 Mounting
The receiver should be mounted in an area that is relatively free of large metal obstructions such as ductwork, appliances,
wire lath, etc. The enclosure can be attached to a wall, fence
1
, etc. with the 4 mounting holes provided on the base of the
unit.
The receiver comes mounted on the lid of the enclosure. This allows ample space for cabling, conduit entrance, etc. If
required, the receiver may be mounted to the base of the enclosure. To insert the 4 conductor cable into the enclosure, take
a small screwdriver, or other small sharp object and push it through the grommet opening. Continue pushing until it
pierces the interior of the grommet. Remove the screwdriver and insert the cable through the grommet.
NOTE: It is recommended to attach a tie wrap around the cable at the grommet and if more strain relief is needed mount
a “P” clamp to a nearby boss using a #4 self tapping screw.
7.0 Receiver Read Range
To insure the receiver is located in a good coverage area when first installing:
1. Take a clicker to the furthest point where coverage is desired. Depress the appropriate button twice and have someone
watch the LEDs. Both the Red and Green LEDs will blink off momentarily if you are in range.
2. If the receiver range is greater than desired, proceed as above and have someone turn the Range Adjustment control
counter clockwise until the LEDs do not respond. Then turn clockwise by a degree or two. If the LEDs now respond,
the receiver range has been set to the location desired.
3. If the receiver is mounted in a metal housing, or in some other location that adversely affects the read range, an
external antenna will need to be mounted. To add an external antenna, open the grommet on the top of the enclosure
as previously done for the data cable.
4. The coaxial cable is passed through this and connected to the external antenna terminal at the top of the receiver
board. Make sure to connect the coax shield to the “GND” connector and the center conductor to the “ANT.”
5. Mount the antenna in a location that allows the desired read range.
1. A metal fence will require the use of an external antenna.
