1. Default 4800bps, 8 , N , 1 , 

2. Protocol for MODBUS - RTU , effective register follows

＜MODBUS-RTU 프로토콜＞

1. function code 0x03 : read multiple registers

• Example: To read the address of the host 01 , the start address 0048H of two slaves register data
• The host sends : 01  03  00  48  00  02  CRC
• Slave response : 01  03  04  12  45  56  68  CRC
• example : receive data(0048 to 004C) - Device Adderss : 01
• Sending data for : 01  03  00  48  00  05  05  DF
• The data returned is : 01  03  0A  02  6C  11  D7  01  1B  01  02  03  04  DB  6F
• Disaggregated data, the results were as follows :
                  Voltage = 0x026C / 100 = 620/100 = 6.2V
                  Current = 0x11D7 / 1000 = 4567/1000 = 4.567A
                  Power = 0x011B / 10 = 283/10 = 28.3W
                  Power = 0x01020304 / 100 = 16909060/100 = 169090.6Wh

2. function code 0x10 : Write Multiple Registers

• Example : Write data (Start Address : 0000)
• The host sends : 01  10  00  00  02  04  00  00  0C  00  00  F3  FA
• Slave response : 01  10  00  00  02  81  0C  CB

<어드레스 확인방법>

• The host sends : 00 03 00 04 00 01 C4 1A
• Slave response : 02 03 02 02 05 3D 27
  - 0x02 : 장치 어드레스
  - 0x05 : 통신속도 (4800bps/8/1/N)
