  • Enable COM port mapping:

    ☑ COM port mapping is enabled. (default)

  • Server COM Port starts with: Specifies the lowest device number that is used on the server for mapping. Possible values:
    • COM 1 to COM 6. (default: COM1)

      "COM 2" 
      "COM 3" 
      "COM 4" 
      "USB COM 1": For UD3-LX60 devices (mainboard: M350C), this port must be used instead of "COM 1".
      "USB COM 2" 
      "USB COM 3"

  • Detect Devices...: Opens a dialog allowing you to select the device file. 3 device files are available for each device; the Description column shows the type of device file:
    • (GENERIC) [device designation]: Generic type. The name of the device file ends in a consecutive number which depends on the boot procedure or the order of insertion. Example: /dev/ttyUSB0
    • (BY PORT) [device designation]: According to the USB port. The device file is in the /dev/usbserial/ directory. The name of the device file ends in the number of the USB port that the device is plugged into. Example: /dev/usbserial/ttyUSB_P12
    • (BY USBID) [device designation]: According to USB ID. The device file is in the /dev/usbserial/ directory. The name of the device file ends as follows: _V[Vendor ID]_P[Product ID]. Example: /dev/usbserial/ttyUSB_V067b_P2303
    • (Virtual) [device designation]: Virtual device; used for signature pads for example. Example: /dev/ttyVST0

    If your device has an additional multiport PCI card, more than 2 connections may be available.

    If you would like to use signature pads, you must enable them beforehand under User Interface > Input > Signature Pad.
