Remote data acquisition systems
EPOS equipment, barcode scanners
Wireless computer peripheral networks
Remote monitoring and control systems
PDA and laptop peripheral connectivity
Portable logging equipment
Easy and Reliable
Addressable data packets with error checking, packet acknowledgements and retransmissions are used to
achieve a reliable wireless point-to-point/point-to-multipoint data link. Built for ease of use and rapid
installation, the RS232 interface ensures direct connection to serial equipment while the built-in diagnostics
aid with site evaluation and network configuration.
Extending Range
Use an external antenna to improve range where the helical or ¼ wave whip antennas are not ideal.
Additionally the modems can be configured as a repeater to further increase the operational range. Note the
use of a high gain external antenna may result in radiated power levels above the licensed levels permitted in
the country of use.
Broadcast Multi-drop Networks
When configured for broadcast multidrop mode the modem can be combined with any number of intelligent
host computers/controllers to implement large scale multipoint radio networks.
