3 Installing the RF Re-
ceiver
Installing an RF Receiver requires mounting
the receiver, powering the receiver, and network-
ing the receiver together with other receivers and
gateways on the RS485 Token Ring Network.
3.1. Mounting and Placement
of the RF Receiver
3.1.1. Environmental Operating
Conditions
The RF Receiver should be mounted in an
environment with ambient temperature between
30°F and 120°F, with a non-condensing relative
humidity between 5% and 95%.
3.1.2. Placement
The RF Receiver must be placed above the
sales floor within 150 feet of the sensors it will
receive transmissions from. Each RF Sensor in
the store must be no more than 150 feet from an
RF Receiver, so for installations that require
multiple receivers, make sure each RF Receiver
is placed so that all RF Sensors have a receiver
within the maximum distance.
3.1.3. Mounting
The receiver may be mounted either against
the ceiling (with the antenna pointing toward the
floor) or on top of a case (with the antenna point-
ing directly toward the ceiling). Alternately, the
receiver may be mounted sideways (e.g. on a
riser or a wall), but this will limit the range of
reception to only those RF Sensors that are
within the 180° arc of the direction the antenna
is pointing (i.e. it may not pick up sensors
located behind the receiver base).
Note the status LEDs and wire connections
are located on the bottom of the receiver enclo-
sure; try to mount the receiver so that these con-
nections are accessible.
3.2. Powering the RF Receiv-
er
The RF Receiver requires a 9VDC power
source. A 110VAC to 9VDC transformer is sup-
plied with the RF Receiver. Plug the adapter into
the receiver base, and connect the transformer to
a 110VAC line.
3.3. Wiring the RF Receiver to
a CPC Site Controller
Each RF Receiver passes along sensor val-
ues it receives to an RF Gateway on its RS485
Token Ring Network.
