The OMWT-XREC-SER Wireless
Transceiver is a general purpose
compact data transceiver perfect
for those needing high performance
and dependable operation. Its
wireless modem transfers data
at 9600 baud up to 1/4 mile in a
city environment with 1/2 wave
antenna or greater than 10 miles
line-of-sight with a YAGI
directional antenna.
It is ideally suited for applications
in supervisory control and data
acquisition (SCADA), remote meter
reading, home automation, security,
instrument monitoring, point of sale
systems (POS) and myriad other
applications.
Transceiver modules have built-in
support for multi-drop networking
protocols. Multiple independent
networks can operate in the same
vicinity by using distinct network
identifiers.
The radios integrate quickly and
seamlessly into any new or existing
design. Simply output serial data
from a micro-controller or RS-232
port into the radio to send FCC
approved, frequency hopping
spread spectrum data through the
air and capture it on all receivers
within range on the same network.
The system behaves as a virtual
half-duplex parallel-wired network.
The OMWT-XREC-SER-900 wireless
transmitter is supplied standard
with a 1/2 wave monopole antenna.
For longer distance outdoor use,
optional Omni-Directional and YAGI
directional line-of-site antennas
are available.
Used with OMWT Wireless Transmitters
When used in conjunction with the OMWT series wireless transmitters and OMWT-REP repeater, process data from the wireless
transmitter may be sent up to 20 miles(with appropriate antenna).
