Hi Raghavendra,

You need to count server address from the serial number. Formula is : 0x4000 | SN % (10000 + 1000).

Hi Raghavendra,

You communicate as with one meter. You just change server address from 1 to serial number.

You count server address using this formula:

0x4000 | [Server address] % (10000 + 1000).
