1035 +** Register VD: Use only registers that are multiples of 4, such as 0, 4, 8, etc.
1036 +** Register VW: Use only registers thay are multiples of 2, such as 0, 2, 4 etc. (Using an odd-length register may result in data errors, such as 2 3 4 )

2183 +== **Communicate with Modbus Meter** ==
2184 +
2185 +The following example is using the Linfee meter LNF96EY to demonstrate how to set up the Modbus communication.
2186 +
2187 +~1. Wiring the RS485 cable first. Because the pin 58 is A, the pin 59 is B for meter. Here we use the COM1 to connect. So the diagram like follows:
2188 +
2189 +(% style="text-align:center" %)

2191 +
2192 +2. Check the specific Modbus parameter in the communication menu from LED display.

2194 +So from the following pictures, we can know the Meter Address is 85, Baud rate is 9600, CRC None.
