ET69C02 FAQ
ET69C02 ， Hi, we have a lot of your network modules connected to your relay modules.
we have encountered an issue.
The network modules loose their connection to the network. They start working fine after setup but in time just loose connection and there is not ping to them and no web interface, until you restart the network module, and sometimes even have to reset the module.
We have tried to increase the voltage to 12.9-13.0 volts, but it did not work.
This is our general configuration:
Answer :
1 The power supply may be disturbed. Please use an independent DC 12V power supply
2 The network interface may be disturbed. Please change the network cable environment
3 If the problem still cannot be solved, please replace the ET69C02 board.
