setting mode. In the normal situation, it needs to set the DIP switch to the “Normal”
position. In this case, the GW-7553 module can communicate with Modbus devices.
When the user sets the DIP switch to the “Setting” position, the GW-7553 module can
communicate with the utility to set the safe value and network configuration.
