Sealevel's New SeaPORT+4/485 USB serial I/O Adapter provides four RS-422/485 serial ports for USB connectivity to legacy or non-USB compliant devices. SeaPORT RS-422/485 adapters support standard PC data rates up to 921K bps. Simply install the included software and connect the SeaPORT adapter to your USB port. The device is immediately recognized by the system. At that point, simply connect the adapter to your target device (i.e. modem, serial printer, scale, bar code/mag stripe reader, etc.). Now your non-USB peripherals can have the same connection simplicity and ease of use as USB aware peripherals. We include our Windows 98/ME/2000/XP and Linux drivers to simplify installation.
