SCALE WEIGHT DATA STRINGS
AS-330D Pounds/Ounces Mode: SspppbLBbww.wbOZbxccE
Where: S = ASCII STX (HEX 02)
s = weight sign (space or -)
ppp = weight lb, leading zero suppressed
b = space
LB = the text "LB"
ww.w = weigh ounces, leading zero suppressed
OZ = the text "OZ"
x = status: M = motion on scale
C = scale over capacity
cc = checksum - these two characters are the ASCII
representation of the computed checksum
E = ASCII ETX (HEX 03)
Pounds Only Mode:
AS-330D / AS-334D: swwwww.wwxccE
AS-333D: swwwww.wwwxccE
Where: s = weight sign (space or -)
wwwww.ww = weight - AS-330D / AS-334D (pounds and 2 position
decimal weight including the decimal point)
wwwww.www = weight - AS-333D (pounds and 3 position decimal weight
including the decimal point)
x = status: M = motion on scale
C = scale over capacity
cc = checksum - these two characters are the ASCII
representation of the computed checksum
E = ASCII ETX (HEX 03)
Kilograms Mode:
AS-330D: swwwww.wwxccE
AS-333D / AS-334D: swwwww.wwwxccE
Where: s = weight sign (space or -)
wwwww.ww = weight - AS-330D (kilograms and 2 position decimal weight
including the decimal point)
wwwww.www = weight - AS-330D and AS-334D (kilograms and 3 position
decimal weight including the decimal point)
x = status: M = motion on scale
C = scale over capacity
cc = checksum - these two characters are the ASCII
representation of the computed checksum
E = ASCII ETX (HEX 03)
If an internal error occurs, the scale will respond with an error string, SEnccE
Where: S = ASCII STX (HEX 02)
E = the Capital letter "E"
n = error code number:
1 = invalid calibration
2 = analog failure
4 = attempt to zero outside zero range
5 = non-volatile ram write error
9 = conversion factor error
cc = checksum - these two characters are the ASCII
representation of the computed checksum
E = ASCII ETX (HEX 03)
