16-Port USB to Serial Adapters

Date: 09/30/2005

Sealevel Systems, Inc. announces two additions to the popular SeaLINK? USB product line, the SeaLINK+16/232 and the SeaLINK+16/485. Offering 16 independent serial ports, SeaLINK+16 devices are the perfect way to connect multiple peripherals such as barcode scanners, serial displays, and data acquisition modules to any USB port.

The serial ports on each SeaLINK+16 appear as standard COM ports to the host system enabling compatibility with legacy software. All Sealevel SeaLINK USB serial adapters use a state machine architecture that greatly reduces the host computer?s overhead when communicating over multiple ports simultaneously. Data rates up to 921.6K bps are supported, and the SeaLINK+16/485 offers RS-232/485 selectivity through cabling. Two convenient USB 1.1 downstream connections are also provided to allow daisy chaining SeaLINK devices or interfacing standard USB peripherals.

SeaLINK+16 products ship with Sealevel Systems? SeaCOM? suite of Windows 95/98/ME/NT/2000/XP drivers. Also included is WinSSD, a full-featured application providing powerful testing and diagnostic capabilities. Use WinSSD for BERT (Bit Error Rate Testing), throughput monitoring, loopback tests, and transmit test pattern messages. In addition to Windows drivers and utilities, SeaCOM? includes drivers, utilities, application notes to simplify installations in DOS, QNX, and LINUX.

The SeaLINK+16/232 and SeaLINK+16/485 are housed in rugged 1U rackmount metal enclosures suitable for a variety of applications and environments. Standard operating temperature range is 0-70?C, and extended temperature range (-40-+85?C) models are available. Prices start at $729 for the SeaLINK+16/232, part number 2161, and product is available immediately from stock. Like all Sealevel I/O products, each SeaLINK+16 is backed by a lifetime warranty.
