0-40℃,0-95%RH
Overviewȱ
The INNCOM PC-502.2 wall mounted module can be used to expand the
range of a Layer-2 RF network or provide the protocol gateway from
INNCOM S5-bus to Layer-2 RF protocol.
In the Layer-2.2 802.15.4 Zigbee 2006 mesh network, the PC-502.2 is
designed to patch areas within the network where signal strength is lost
due to distance limitations or interference. It also serves to create multiple
pathways, increasing the redundancy of the mesh communications to
ensure maximum network reliability.

x 2.4Ghz IEEE 802.15.4 compliant RF transceiver (CC2430 radio
core)
x Medium and long range variants available
x Industrial temperature ratings 0-65 degrees C
x FCC Part 15b listed

Ranges are determined by performing an RF link quality test using e528.3G thermostats as the
transmitter and the PC-502.2 as the receiver. The maximum distance threshold is based on a 95%
overall link quality. Outdoor ranges were conducted in a low noise, free air environment. Indoor
ranges are for reference. Indoor ranges are affected by the ambient environmental noise floor and
building construction materials.
NetworkȱTopologyȱ
Figure 2 PC-502 Layer-2 Topology
In this application, the PC-502.2 in participation with the e529.RF provides the Layer-1 to Layer-2
RF Bridge where both wireless in-room and wireless back-end networking are required. The PC-
502.2 can also patch areas within the Layer-2 network where signal strength is lost due to distance
limitations or interference.

The PC-502.2 must be bound to the controlling device (e.g., the E529.RF in Figure 2 above) to
receive configuration information. On the E529.RF in service mode

x Set the value to 3 and press Display
x When Display is pressed, the e529.RF sends Layer-2 configurations to the PC-502.2. (This
function does not offer any feedback on the screen so it is recommended that the Display
button be pressed 3 or 4 times to ensure configuration.)

Warning
Any Changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
This device complies with part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment .This equipment should be installed and operated with
minimum distance 20 cm between the radiator& your body
Note: This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
