Industrial USB to serial adapters

Sealevel Systems has released two additions to the SeaLINK USB to serial product line—the SeaLINK+4M.SC and SeaLINK+8M.SC. The units’ four or eight serial ports are software-configurable for RS-232, RS-422, or RS-485 without the need to open the enclosure to change jumper settings or dipswitches.

Sealevel Systems has released two additions to the SeaLINK USB to serial product line—the SeaLINK+4M.SC and SeaLINK+8M.SC. The units’ four or eight serial ports are software-configurable for RS-232, RS-422, or RS-485 without the need to open the enclosure to change jumper settings or dipswitches. The devices maintain electrical interface settings locally, allowing host computer repairs or upgrades without reconfiguring ports. Devices can be configured at one computer and deployed to others. Serial ports on each adapter appear as standard COM ports to the host computer, enabling compatibility with legacy software. Adapters use a state-machine architecture that reduces the host computer’s overhead when communicating over multiple serial ports simultaneously, while supporting data rates to 921.6K bps. Status LEDs indicate power, serial data activity, and electrical interface. Each includes an industrial grade wall-mount power supply. Input power is connected to pin 9 on each DB9M connector for powering common 5 V serial peripherals. www.sealevel.com Sealevel Systems
