Vi-Link AR42 is a high-quality point-to-point one-channel Air Fiber modem. It is designed to link a remote device to the host computer up to 30 Km via a high-power 2.4 GHz antenna. Users may plug the AR42 into any selectable EIA-RS232 or EIA-RS422/485 interface.
The AR42 can transfer asynchronous data up to 115.2 Kbps with RS-232 or RS-422/485 interfaces. Point-to-point transmission distances can be used anywhere up to 70 Km with a 2.4 GHz or 5.8 GHz RF antenna.
The AR42 is designed for any general-purpose application between data communication equipment. Typical applications include remote devices to host computer connections, tail circuits to multiplexers, monitoring equipment to a central control system, and situations requiring extended distances. It may also use in harsh environments because its extended operation temperature.
Applications for the AR42 include campus fiber Traffic Control System, Metro Operation System, SCADA systems, Campus Networks and military applications.
