Frequently asked questions​

How do I enter and exit the HD340 configuration mode?
Scan the "Enter Setup" code, then the codes for the settings you want, and finish with "Exit Setup".
Does the HD340 need drivers?
No. In its default USB keyboard mode the HD340 is recognised automatically by Windows, macOS and Linux, with no drivers. It can also work as a Virtual COM (serial) device.
Does the HD340 read codes from phone and computer screens?
Yes. The CMOS sensor reads 1D and 2D codes, including QR codes, from printed labels as well as from LCD and mobile-device screens.
How does the automatic (presentation) scanning work?
Placed on a counter, the HD340 senses a code brought in front of it and reads it automatically without pressing a button — ideal for point-of-sale use.
