USB Interface
Introduction
There are four options for USB connection, and any of them could be set as the default protocol on demand.
USB HID-KBW: it emulates the unit`s transmission to a USB keyboard input with no need of command
»
settings or loading any 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 Co., Ltd,
»
which requires installation of a speci
fi
c driver on the Host. It supports data transmission and user preference
programming. The DataPipe driver for Windows is available in http://www.nlscan.com/home.php.
USB COM Port Emulation: it emulates the USB port on the Host to an RS 232 port with the same data
»
transport and settings as the real RS 232 port. This connection mode is based on USB DataPipe protocol and
requires the USB DataPipe driver, too.
HID-POS: it is based on the HID port, with no need for customized driver installation. Its transmission
»
is much faster than that of virtual keyboard and traditional RS 232 interface.
When a USB connection and an RS 232 connection are used at the same time, the unit will select the USB
connection by default for its priority.
