5.5 Communication examples
Example 1: Read the current switch status of the remote communication unit with instrument address 2.
Send: 0x02,0x03,0x50,0x10,0x00,0x02,0XD4,0xFD
Return: 0x02,0x03,0x04,0x00,0x00,0x00,0x03,0x89,0x32
Note: The first and second channel switches of the remote communication unit with instrument address 2 are
connected, and the remaining 30 channel switches are disconnected.
Example 2: Read the status of 1 to 5 switches
Send: 0x01,0x02,0x00,0x00,0x00,0x05,0xB8,0x09
Return: 0x01,0x02,0x01,0x10,0xA0,0x44
Note: 0x 10 is converted to a binary number of 0001,000, that is, the fifth switch is in the connected status, and
the rest are in the disconnected status.
Example 3: Read the status of 1 to 32 switches.
Send: 0x01,0x02,0x00,0x00,0x00,0x20,0x79,0xD2
Return: 0x01,0x02,0x04,0x00,0x00,0x8E,0x04,0x9F,0x81
Note: 0x00,0x00,0x8E,0x04 are converted to binary numbers of 0000,0000,0000,0000,1000,1110,0000,0100,
that is, the switches of paths 18, 19, 20, 24 and 27 are in the connected status, and the rest are in the disconnected
status.
Example 4: Read the status of 17 to 32 switches.
Send: 0x01,0x02,0x00,0x10,0x00,0x10,0x78,0x03
Return: 0x01,0x02,0x02,0x8E,0x04,0xDD,0xDB
Note: 0x8E,0x04 are converted to binary numbers of 1000,1110,0000,0100, that is, the switches of paths 18, 19,
20, 24 and 27 are in the connected status, and the rest are in the disconnected status.
Example 5: Set the current time.
Send: 0x01,0x10,0x10,0x2C,0x00,0x03,0x06,0x15,0x02,0x18,0x11,0x06,0x1E, 0xDD,0x1D
Return: 0x01,0x10,0x10,0x2C,0x00,0x03,0x45,0x01
Note: It indicates that the time is set to 17:06:30 on February 24, 2021 (note the BCD code format).
