DESCRIPTION

These spread spectrum transceivers provide reliable long range data communications. Using frequency hopping spread technology, these transceivers are capable of uncompressed data rates of 115.2 Kbps over distances of 20 miles or more. As well as providing long range reliable data links, these transceivers set up quickly and incur no ongoing fees, unlike cellular and land line communications. Monthly telephone company costs are eliminated.

The transceivers operate point to point or point to multipoint. selectable using any async terminal program. Repeaters may be used to extend the range by programming the intermediate unit to operate as a store and forward unit. With up to two repeaters in a link and external antennas, links of 60 miles and beyond are possible.

Transceivers are assigned unique electronic serial numbers at the factory, providing control of who does and who does not have access to the data. An optional mode allows the transceiver to respond to a set of AT commands.

When unsed with the EtherSeries Bridge, the DCB-115 may be used to create a wireless bridged LAN... even a point-to-multi-point configuration.

The SR-VM voice multiplexer allows the DCB-115 to transmit up to four channels of digitized voice along with data. Applications include:

• Emergency back up links
• SCADA - data collection
• Campus links for schools, colleges, manufacturing plants, offices
• Data links to billboards and signs
• Data links for remote control equipment
• Home to office links
• Computer to computer, terminal or multiplexer links
• Lan to lan bridged and routed links
