The 2108 is a single port embedded USB to RS-232 serial adapter intended for mounting directly to a PCs chassis, eliminating the need for external converters and providing a clean, professional installation. The board is USB bus powered, capable of data rates to 460K bps, and installs inside a low profile computer in a spare bracket location. The 2108 includes a low profile PC bracket and a 14" USB header cable (Item# CA260) that connects to most motherboard USB box header connectors and uses only one USB port per serial port. If you need a standard PC bracket, order 2108S. Other USB header cable options are available on a custom design basis.
