Introduction

There are four options for USB connection.
 USB HID-KBW: The scanner's transmission is simulated as USB keyboard input with no need for command
configuration or a driver. The barcode data could be entered by the virtual keyboard directly and it is also convenient
for the Host to receive data.

USB DataPipe: USB DataPipe is a transport protocol developed by Newland Auto-ID Tech, which requires
installation of a specific driver on the Host. It supports data transmission and device configuration on QuickSet. The
DataPipe driver for Windows is available at http://www.nlscan.com.

USB COM Port Emulation: The USB port on the Host is emulated as a RS-232 port with the same data transmission
and configuration as a real RS-232 port. This mode is based on USB DataPipe protocol and requires the USB
DataPipe driver, too.

HID-POS: It is based on the HID interface, with no need of a custom driver. It excels virtual keyboard and traditional
RS-232 interface in transmission speed.
When the scanner is connected to both USB and RS-232 ports on a Host, it will select the USB connection by default.
