Cause: Baud rate mismatch between Driver 20 defaults (9600, 8, N, 1) and your POS software. Fix:
| Interface | Driver Needed | Typical Version | |-----------|--------------|------------------| | USB Keyboard Wedge | No driver (HID keyboard) | N/A | | USB Virtual COM | Zebex USB-Serial driver | 2.0.0.0 – 2.0.2.0 | | RS-232 | None (standard serial) | N/A | | PS/2 | None | N/A |
So “Driver 20” most likely = USB-to-Serial driver v2.0.x.
Search for "Z-6170" and filter by "Driver." Look explicitly for file names containing Z6170_Driver_v20.exe or Z6170_Setup_2.0.zip.
