    The serial port must have the following settings: 8N1 (8 data bits, no parity, 1 stop bit). If you are using the Basler Camera Configuration Tool Plus to configure the camera, the tool will detect the characteristics of the serial port on the frame grabber and will determine the appropriate settings so that the tool can open and use the port.
