Units Link Serial Devices To Ethernet Networks

Employing industry-standard TCP/IP protocol, the SeaLINK family is said to permit almost any host to access serial ports as easily as if the ports were host PC cards. The serial device drivers come in 1-, 2-, 4- and 8-port versions, with each port configurable via software as a serial port. Once connected to the network, the serial devices can be controlled and monitored over the Internet, if desired. Said to be simple to install and easy to configure, the microprocessor-based SeaLINK units can communicate over multiple ports at sustained rates of up to 230 Kbps, with customization available for permitting application-specific tasks, such as data collection, to be offloaded to a SeaLINK. Mounting options, including DIN rail, are also available. SeaLINK products work under various Windows and Linux OSs and are available as multi-interface RS-232/422/485 or RS-422/485 ports or RS-232 only. Prices begin at $299 each.
