Overviewȱ
The PC-502 is a wall mounted module that can be
used to expand the range of a Layer-1 or Layer-2 RF
network, or can be used to provide the protocol gateway
from S5-bus to Layer-1 or Layer-2 RF protocol.
In the Layer-1 RF network the PC-502 is designed to provide
S5-bus to RF protocol conversion to allow any
product participating in the Integrated Room
Automation System (IRAS) an RF transceiver for control of
wireless products in the guestroom.
In the Layer-2 802.15.4 Zigbee 2006 mesh network, the PC-
502 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.

Ranges are determined by performing an RF link quality test using e528.3G thermostats as the
transmitter, and the PC-502.x 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 impacted by the ambient environmental noise floor,
and building construction materials.

In this application, the PC-502 acts as the S5-bus to RF gateway in the Layer-1 network. This
would allow products that do not inherently support an RF radio to participate in the Layer-1
network. The PC-502 could also be used as a repeater to re-broadcast network traffic into areas
that are difficult to maintain sold RF network links.

In this application, the PC-502 provides the Layer-1 to Layer-2 RF Bridge where both wireless
applications are required. Additionally, the PC-502 could be used as a repeater to improve the link
quality on the Layer-2 network.ȱ
