Toledo Scale Continuous Output
Message Format
A valid message begins with a startĆofĆmessage character (ASCII STX). The
message contains three bytes of status information, six bytes of indicated weight,
and six bytes of tare weight. The message is terminated by a carriage return. A
single byte checksum follows the carriage return. The checksum is calculated by
taking the 2's complement of the sum of bits 0Ć6 of all characters preceding the
checksum character.
