Installation of the module on the site, to mark goods with plates: Action, etc.

I had 3 modules, and I couldn’t deal with any of them. I asked for help, recorded a video of how I adjusted, the answer did not follow. With better communication, I would refuse.

Everything was done according to TZ at 100%., instead of one module was installed 3, the setting in TZ did not enter, the connection did not come out in time due to communication problems.
The work was not paid to me, I do not advise the customer, because the TZ is not complete and you will eventually stay free of charge and with a negative feedback!
