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).
