STEP-BY-STEP INSTRUCTIONS
It is recommended that the Access Point radio be installed first. In
this way, the operation of each associated Remote can be checked
as it is placed on the air.
NOTE: Transceivers are shipped from the factory set to the
"Remote" mode unless marked differently.
3.1.1
Step 1—Mount the Transceiver
NOTE: To prevent moisture from entering the radio, it should not
be mounted with the connectors pointing up. Also, cables
should be routed in a manner that prevents moisture from
running along their surfaces and into the radio.
Attach the mounting brackets to the bottom of the radio with the
screws provided. Mount the radio to a stable surface with
appropriate fasteners (not supplied).

CAUTION
The screws holding the mounting brackets to

internal damage may result.
DAMAGE
The radio chassis should be bonded to a common station ground.
If the mounting surface is not grounded, a ground wire may be
attached to one of the screws on the radio's enclosure.

Step 2—Install the Antenna
The antenna should be mounted in the clear, with an unobstructed
path to all associated stations. To minimize RF interference, it
should be mounted at least nine inches (> 23 cm) from connected
device(s), sensors and other components of the system. The use
of low loss, high quality coaxial cable is recommended, and it
should be kept as short as possible to minimize loss.
3.1.3
Step 3—Measure & Connect Primary Power
The primary power at the power connector must be within 10.5–30
Vdc and be capable of continuously providing up to 580 mA of
current. A power connector with screw-terminals is provided with
each unit. Strip the wire leads to 6 mm (0.25") before inserting
them in the connector. Be sure to observe proper polarity as shown
in Figure 4 with the positive lead (+) on the left side.

EQUIPMENT
DAMAGE
The power supply used with the transceiver should be equipped
with overload protection (NEC Class 2 rating), to protect against a
short circuit between its output terminals and the unit's power
connector.
