USB serial adapters

Sealevel Systems has announced two additions to its SeaLink USB to serial range, the K+4.SC and the +8.SC.

Offering four or eight serial ports that are software configurable for RS232, RS422, or RS485, the adapters eliminate the need to open the enclosure to change jumper settings or dipswitches.

They 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 adapter appear as standard COM ports to the host computer enabling compatibility with legacy software. All 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 921.6 Kbps.

The devices are USB bus powered and both models include retentive USB type B connectors to help prevent unintentional disconnection from standard USB cables.

The +8.SC also integrates a SeaLatch locking USB port, which is fully compatible with standard USB cables.

The adapters are supplied with the Sealevel Systems SeaCOM suite of Windows drivers and diagnostic utilities.
