SeaLATCH™ USB
SeaLINK USB serial adapters integrate the patent-pending SeaLATCH USB port,
which is fully compatible with standard USB cables. When used with the included
USB cable (Item# CA356) with a SeaLATCH USB type B connector, the metal
thumbscrew provides a secure connection to the device and prevents accidental cable
disconnection.
