Message format

The syntax of the message is shown below. <0xA0,0xA1><0x0D,0x0A>


Checksum (CS) field is transmitted in all messages.

The checksum field is the last field in a message before the end of sequence field.

The checksum is the 8-bit exclusive OR of only the payload bytes which start from Message ID until the last byte prior to the checksum byte.

A reference to the calculation of CS is provided below,

CS = 0, N=PL; For n = 0 to N CS = CS ^ <Payload Byte # n>
