Product Description:

Serial ports on USB allow further use of existing devices, even when the computer doesn’t offer serial ports. The high speed serial port with the 128 byte FIFO allow high speed communication, even in heavy loaded systems.

The USB-2COMi-M provides two DB9 male connectors & two 6-pin terminal block connectors for optimal flexibility of serial connection. The unique features help to reduce the system load. The serial port also allows unusual speed settings like 500.000bps.
