EMBEDDED
WIRELESS COMMUNICATION MODULES
The XE900M
second-generation Smart Transceiver and the XE924M Base
Access Point add a number of performance and feature
enhancements to their predecessors. The XE900M and XE924M
provide a low-cost and convenient solution to collecting
data wirelessly from up to 128 discrete nodes located
within a 150 (indoor) radius.

The XE900M
Smart Transceiver combines a microcontroller and 900-MHz
transceiver in a miniature, dual-in-line package. It
can communicate with another Smart Transceiver or with
the XE924M Base Access Point to create a data collection
network. The count-off function has been enhanced to
enable the network hub to quickly check the status of
the up to 128 network nodes.
The XE900M
is also capabable of communicating using up to 126 carrier
frequencies within the 900-MHz ISM band. The availability
of multiple channels reduces interference problems by
permitting a change in the communication channel if
noise levels affect data throughput. Multiple frequency
channels also permit the network to include more than
one Base Access Point. Multiple Base Access Points operating
on different frequencies can extend both the distance
and number of nodes within the network. The Sensor-On-Air
function allows two analog inputs and four digital I/O
lines to be monitored and/or manipulated by the Smart
Transceiver’s communication controller. Nodes can be
easily added to the Base Access network without any
additional hardware installation other than the installation
of an XE900M Smart Transceiver into the new equipment.
The XE924M
Base Access Point combines a 900-MHz transceiver and
a communication controller housed in a miniature, dual-in-line
package. The XE924M eliminates dial-up hardware redundancy,
and therefore reduces both the initial installation
cost and continuing operating costs. Agency approval
is simplified because the integration modem includes
transferable Part 68 Approval and is a UL-recognized
component. The 900-MHz transceiver complies with FCC
Part 15 rules.
The unit
price of the XE900M Smart Transceiver is $39,
and the XE924M Base Access Point is $59 in OEM
volumes.
