USB to Serial RS232/422/485

The USB-COMi-PRO range is completely jumperless and free of DIP switches, all configuration is done by software. Just press the button and use the configuration program.

Serial ports on USB allow further use of existing devices, even when the computer doesn’t offer serial ports. Now the USB-COMi-PRO is extremely flexible in offered communication standards. Besides the classical RS232 and RS422 it offers three variants of the RS485 operation. The often required Termination and Polarization (BIAS) is also provided by built-in hardware, and it is controlled by the same configuration software.

The driver allows to configure the serial ports for bitrates of up to 3Mbit/s. In RS232 mode the bitrate is limited to 1 Mbit/s
