D. Data Transmission
Data is transmitted on DEMAND from the host device. Data available for transmission
consists of the GROSS weight. Transmission to the host will occur when the host
transmits a carriage return (HEX 0D) to the scale.
E. Computer Output Format
The instrument will transmit the following string of data.
NOTES
1. Characters denoted by “X” are characters 0-9. Leading zeroes are replaced with
spaces (SP). Character 6 is a decimal point (HEX 2E). The decimal will move to
the fifth (5) character position when at .05 kg.
2. Lower case “I” and “b” for Avoirdupois units or “k” and “g” for metric units.
3. The first weight character will be a minus (-), HEX 2D, if weight is negative.
4. Characters separated with a “ / ” denote one of the characters will be transmitted.
5. Lower case “gr” in characters 12 and 13 indicates scale motion.
Upper case indicates stable weight.
6. EOT, HEX 04 is transmitted when:
a.
Power-up occurs and scale is NOT at ZERO
b. Scale senses Overcapacity
7. Transmission will occur when a CR (Hex 0D) carriage return is received.
