2823 SeaLINK+8.SC USB to 8-Port RS-232, RS-422, RS-485 (Software Configurable) DB9 Serial Interface Adapter

The SeaLINK® 2823 USB to serial interface adapter offers an easy way to connect up to eight serial devices to a single USB port. All configuration and electrical interface selections are handled through the driver, eliminating the need to open the enclosure to set jumpers or switches. Each serial port is software configurable for RS-232, RS-422, or RS-485 with the electrical interface settings maintained locally, allowing the host computer to be repaired or upgraded without reconfiguring the serial ports. Additionally, the 2823 can be configured at one computer and deployed to other computers. Sealevel's SeaCOM USB software drivers and utilities make installation and operation easy using Windows 98SE, ME, 2000, XP and Vista operating systems. After installing the software, simply plug the 2823 into an available USB port and the serial ports are recognized as standard COM ports by 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 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 2823 integrates a patent-pending SeaLATCH USB port, which is fully compatible with standard USB cables. When used with the included USB cable with a SeaLATCH USB type B connector, the metal thumbscrew provides a secure connection to the device and prevents accidental cable disconnection. Additionally, the highly-retentive type B connector helps prevent unintentional separation from a standard USB cable. The 2823 is USB bus powered, so no external power supply is needed. Standard operating temperature range is 0°C to 70°C and extended temperature range (-40°C to 85°C) is optional.
