Description

The SeaLINK® 2802 USB serial I/O adapter provides eight RS-422 or RS-485 serial ports for USB connectivity to legacy or non-USB compliant devices. Each serial port can be individually configured via dipswitches located inside the enclosure.

The 2802 is housed in a rugged metal enclosure making it ideal for rugged and industrial environments. The adapter integrates Sealevel’s SeaLATCH locking USB port, which is 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. Additionally, the high-retention type B connector helps prevent unintentional separation from a standard USB cable.

Sealevel SeaCOM USB software drivers and utilities make installation and operation easy using Microsoft Windows and Linux operating systems. After installing the software, simply plug the 2802 into an available USB port. 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 460.8K bps. Status LEDs on the front of the enclosure indicate power and serial data activity on each port.

Standard operating temperature range is 0C to +70C and extended temperature range (-40C to +85C) is optional.
