USB mode

The mini USB port is used for configuration and basic serial communication. To use the mini USB port, install the XLR PRO USB driver (Windows only) on the host PC. (The driver is available at www.digi.com/support/productdetail?pid=5603&type=drivers.) When connected via the mini USB port, the XLR PRO appears as a virtual COM port on the host. The XLR PRO detects an active virtual DTR signal to determine if a USB connection is active.

When communicating to the XLR PRO using the USB mode, serial settings and flow control are not used. Serial settings (baud rate, parity, and stop bits) can be set to any value on the host PC and do not affect the XLR PRO connection. If a host application requires flow control, use RS-232 serial mode.
