Fast, Multi-Interface 16-Port Ethernet Serial Servers

Date: 03/08/2006

Sealevel Systems, Inc. has introduced three new SeaLINK? Ethernet serial servers, each capable of fast, reliable communications on up to 16 serial ports simultaneously. Offering RS-232, RS-422, and RS-485 connectivity, SeaLINK+16 devices are the easiest, most dependable way to connect multiple serial devices directly to an Ethernet network.

Designed using a powerful embedded microprocessor, SeaLINK+16 products are able to communicate at data rates up to 230K bps. The RS-232 model implements all modem control signals for maximum compatibility with a variety of peripherals. For quick installation, a convenient webpage is used to select the interface mode for each serial port on the RS-422/485 and RS-232/422/485 products. Additionally, the onboard webserver provides access to common serial and network settings, timeouts, and other settings. All configuration can be done from the webpage with no need to set hardware switches or jumpers.

SeaLINK+16 products use industry standard RFC 2217 TCP/IP protocol for maximizing compatibility with the widest range of applications and devices. The included software works under a wide variety of operating systems including Windows 98/ME/NT/2000/XP and Linux, and the SeaLINK+16?s serial ports appear as virtual COM ports to the host machine. Standard serial operating calls are transparently redirected to the SeaLINK+16, guaranteeing compatibility with legacy serial devices and enabling backward compatibility with existing software. Serial tunneling is also available, allowing two native serial devices to communicate over a network. Alternatively, raw data socket mode is supported, eliminating the need for a driver.

Housed in rugged 1U rackmount metal enclosures, SeaLINK+16 devices are suitable for variety of applications and environments. Power indicator LEDs are included on both the front and rear of the enclosure, and each of the 16 RJ45 serial connectors provide both Tx and Rx LED indicators to assist in troubleshooting. Standard operating temperature range is 0-70?C, and extended temperature (-40?C - +85?C) models are available. Prices start at $999 for the SeaLINK+16.232, part number 4161, and product is available immediately from stock. Like all Sealevel I/O products, each SeaLINK+16 is backed by a lifetime warranty.
