XE900S-500 Smart Spread Spectrum Transceiver
Description
The XE900S-500 combines a spread spectrum
transceiver and micro-controller in a single, easy-to-
use, FCC Part 15 Registered module. The embedded
communications controller manages the Frequency
Hopping Spread Spectrum (FHSS) link and the host
system interface.
The XE900S-500 supports two unique features to
simplify wireless networking. Count-Off™ allows the
network master to quickly retrieve the status of 125
remote nodes with a single broadcast command.
SensorOnAir^TM eliminates the need for an application
controller by utilizing the communications controller to
directly manage analog inputs and digital control lines.
Xecom also offers a low power spread spectrum model,
the XE900SL10, for applications that require less range.
The XE900SL10 has an obstructed range of 300 feet but
is smaller, costs less and uses significantly less power.
Features
