3-5 USB interface
USB device type:
HID keyboard– By setting, the image platform is used as a USB HID keyboard emulation device. The
keyboard layout setting follows the setting of keyboard layout in 3-5 USB interface.
USB virtual COM– By setting, the image platform emulates a regular RS232-based COM port. If a
Microsoft Windows PC is connected to the image platform, a driver is required to install on the
connected PC. The driver will use the next available COM Port number. The driver and the installation
guide can be found in the associated CD and on the manufacturer’s website. A Windows-based
software COM_Text is recommended to display the barcode data in text format. COM_Text emulates
some kind of serial-key typing.
Note: When changing USB Device Type, the image platform automatically restarts.
