If you are connecting through TCP, be sure that the device is configured to communicate with port 502.
Warning
NOTE: RS485 Device Addresses
You MUST give each devicea unique address on the RS485 bus. Check the device manual for instructions.
Use lower addresses first (1, 2, ...) because the Sunlight GroupEMS will find them faster!
For each device, it is generally recommended to keep the factory-default baud rate, parity, and stop bits. The Sunlight GroupEMS will scan those first.
