Q : Photovoltaic water pump GPRS module added into the account, but did not respond?
A: If the network and 485 status of GPRS module are displayed on the website, it means it can be used normally.
If only the network is online, check whether there is a problem with the 485 wiring and try to replace the shielded wire. If not, you can contact INVT to upgrade the internal TAC files remotely.
If the network and 485 status are offline, but the device has been connected and powered on, it means that the internal APN information and TAC file need to be updated. Please contact INVT to update.
