Modbus TCP over ethernet (recommended)
- Connect an ethernet cable between the router and the Gantner Q.reader logger, as well as between the router and the ETH1 port of the Teleport. Please navigate to our appendix for more instructions on how to integrate with a router.
- Gantner has to configure their device with the Modbus protocol. Please contact Withthegrid, so we can coordinate this with Gantner.
