3-3 USB interface
USB device type:
HID keyboard– By setting, the scanner is used as a USB HID keyboard emulation device.
USB virtual COM– By setting, the scanner emulate a regular RS232-based COM port. If a Microsoft
Windows PC is connected to the scanner, 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.
The scanner will send the data in data package by the USB interface, if the data package is enabled
(see section "
3-2 RS-232 Interface
"). while the USB works in USB virtual serial port operating mode,
the USB virtual serial port will follow the ACK / NAK flow control, if the RS232 interface uses ACK /
NAK flow control.
Simple COM Port Emulation- Please contact the manufacturer for the instruction.
Note: After changing USB Device Types, the scanner will automatically restart.
Keyboard layout: The scanner supports different national keyboard layouts.
Inter-character delay: This delay is inserted after each data character transmitted.
