USB-COM Plus Mini provides easy serial port expansion over USB 2.0 connecting to high speed RS232 or RS422/485 devices. The device is fully ESD and surge protected, bus powered and accommodated in a tiny metal case. Furthermore, it can operate across a large range of temperature levels to cope with harsh operating conditions. The ISO version is 2.5kV electrically isolated to withstand unbalanced ground loops that arise in hazardous industrial environment. Lastly, both DIN-Rail and wall-mounting options are available.
Flexible Three-Way Serial Ports
The serial port allows different operating modes — which are easily configured using the bottom DIP switch — to fully support RS232, RS422 and RS485 protocols. The differential line termination for RS485 (120Ω) is automatically controlled by choosing the appropriate operating mode. High/Low biasing resistors are not needed; as such, hassle-free usage is guaranteed for the user. Com Port drivers are available for Windows, Linux and Mac OS X. A configuration tool allows easy access to special Windows driver options.
High Speed and Isolation
USB 2.0 full speed connection allows serial data rates of up to 3Mbps for RS422/485 and 921.6kbps for RS232. Every non-standard bitrate (e.g. 500kbps) can easily be set up in the range of up to 960 kbps. The USB-COM Plus Mini is fully ESD and surge protected at the USB and serial port interfaces. Additionally, the serial port are 2.5kV electrically isolated (ISO-version only), making it ideal for deployment in hazardous industrial environments.
