I.Communications Protocol
A)Ground Rules
1)CS= two digit checksum (2 ASCII (Hex) characters)
NOTE: The ">" is NOT included in the checksum calculation
2)CR= one digit camage return (13 or $0D)
3)x= data
4)r= range
5)>=ASCII “>” ($3E)
B)General send format:
1)>cmd letter 0 0# of digits in data data CSCR
2)All characters are sent and received as capital letters,
don’t send lower case letters unless one is specifically requested.
3)Checksum (CS) is always sent or received as a hexadecimal value, e.g.,"A7","BC","2E", etc.
4)Data is always sent or received as a decimal value.
