New Software Configurable 4 & 8 Port Industrial USB to Serial Adapters

Date: 06/23/2008

Product Highlights
  • Each port is software configurable for RS-232, RS-422, or RS-485
  • Electrical interface settings are maintained across multiple computers
  • Includes two USB 1.1 hub ports on front of enclosure
  • 5VDC @ 500mA on pin 9 of each DB9 connector
  • Data rates to 921.6K bps
  • Status LEDs indicate electrical interface and serial data activity for each port

Sealevel Systems announces two additions to the popular SeaLINK? USB to serial product line, the SeaLINK 4M.SC and SeaLINK 8M.SC. Offering four or eight serial ports that are software configurable for RS-232, RS-422, or RS-485, eliminating the need to open the enclosure to change jumper settings or dipswitches. The devices maintain their electrical interface settings locally, allowing the host computer to be repaired or upgraded without reconfiguring the serial ports. Additionally, the devices can be configured at one computer and deployed to other computers.

The serial ports on each SeaLINK adapter appear as standard COM ports to the host computer 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 serial ports simultaneously while supporting data rates to 921.6K bps. Status LEDs on the front of the enclosure indicate power, serial data activity, and electrical interface.

The SeaLINK 4M.SC and SeaLINK 8M.SC are housed in rugged metal enclosures and include two convenient USB 1.1 hub ports for easily connecting additional SeaLINK devices and other standard USB peripherals. These adapters integrate SeaLATCH locking USB ports, which are fully compatible with standard USB cables. When used with the included USB cable with a locking type B connector, the metal thumbscrew provides a secure connection to the device and prevents accidental cable disconnection. Both USB hub ports can also be secured using optional SeaLATCH USB cables.

Each adapter includes an industrial grade wall-mount power supply. Input power is connected to pin 9 on each of the DB9M connectors for easily powering common 5V serial peripherals such as bar-code scanners, receipt printers, and signature input devices. Each serial port can provide up to 500mA to connected serial peripherals.

All SeaLINK products ship with the Sealevel Systems SeaCOM? suite of Windows drivers and diagnostic utilities. WinSSD, a full-featured application providing powerful testing and diagnostic capabilities, is also included. Use WinSSD for BERT (Bit Error Rate Testing), throughput monitoring, loopback tests, and transmit test pattern messages.

Standard operating temperature range for SeaLINK products is 0-70?C, and extended temperature range (-40?C - 85?C) models are available. Both are available immediately from stock priced at $399 for the SeaLINK 4M.SC (Item# 2433) and $619 for the SeaLINK 8M.SC (Item# 2833). Like all Sealevel I/O products, the adapters are backed by a lifetime warranty.
