USB COM Port Emulation
If you connect the engine to the Host via a USB connection, the USB COM Port Emulation feature allows
the Host to receive data in the way as a serial port does. However, you need to set communication
parameters on the engine to match the Host requirements. A driver is required for this feature.

HID-POS
The HID-POS interface is recommended for new application programs. It can send up to 56 characters in
a single USB report and appears more efficient than USB HID-KBW.
Features:

HID based, no custom driver required.

Way more efficient in communication than USB HID-KBW and traditional RS-232 interface.
Note: HID-POS does not require a custom driver. However, a HID interface on Windows 98 does. All HID
interfaces employ standard driver provided by the operating system. Use defaults when installing the
driver.
