Hardware reset to use factory firmware

If a firmware update fails, the PCB can be reverted to its factory installed version of firmware, provided the jumpers (close to the MicroUSB connector) remain accessible.

Jumper positions on VTAP100 PCB v4 or v5 hardware

Position of jumpers on VTAP50 v1a PCB

Jumper positions on VTAP50 VTAP reader PCB v1a hardware

  1. Unplug the VTAP reader to remove power. [This is important because momentarily connecting HWB while the VTAP reader is powered will reset the software (password) lock.]

  2. Connect a jumper across HWB.

  3. Apply power (connect the USB cable to a PC) and wait for the unit to reboot.

  4. Remove the jumper across HWB.
