With this adapter, an update of old versions of the VAX01202 (sold until 2021) is possible via a Windows PC with USB interface. Since 2022 VAX01202 are already equipped with the latest firmware.
The VAX01202 we deliver now need no adapter to change the firmware anymore. They can be connected directly via USB for an eventual update. Until now there is no other firmware for this new VAX01202 model. So there is no update possible for VAX01202 which are delivered after 2021.
The required CH340 driver can be obtained via Windows Update
The firmware for old VAX01202, manual and software are available on request.
