Description
Downloads

The 2803 USB serial I/O adapter provides eight RS-232, RS-422, or RS-485 serial ports for USB connectivity to legacy or non-USB compliant devices.

Each port is individually configurable for RS-232, RS-422, or RS-485. Simply install the included software and connect the 2803 serial interface adapter to your USB port.

The device is immediately recognized by the system. Now your non-USB peripherals can have the same connection simplicity and ease of use as USB aware peripherals.
