Name
Description
Remarks
Command
Indicates the command number sent
The reference value refers to the next GKC instruction
Arguments
Indicates the parameters required to
send the command, the parameters can
be multiple, and different commands
correspond to different data
The reference value refers to the next GKC instruction
*
end of data sign
CheckSum
Checksum data for the entire command
CheckSum value is in the whole command from PGKC
to
CR，LF
end of package sign
*The previous argument XOR value, such as
"$PGKC030,3,1", its check value is the XOR value of
"PGKC030,3,1", its XOR value is 2E
