DATA OUTPUT/COMMAND FORMAT
The following describes commands that may be sent to the scale via its serial port and the format of
the weight and status data transmitted by the scale. Note that the commands are divided into two
groups: those used in the optional pounds only mode (only for AS-350D) and those used in the
pounds/ounces mode (both models). All commands are the ASCII equivalent and transmitted to the
scale.
Pounds Only Mode Selected (Optional-AS-350D only)
W=> Standard Resolution Request to Transmit Scale Weight
(This command can only be used when the scale mode has been set to the
Pounds Only Mode)
Scale Output Format: <STX>Snnn.nn<CR>
where:
<STX>
= ASCII STX
nnn.nn
= scale weight in pounds with decimal point
<CR>
= Carriage Return
If the scale weight is below zero, over capacity, in motion or at center-of-zero, then the status word is
returned in place of the scale weight. See the Status Request Section for the format of the scale
status character.
H=>
High Resolution Weight Request to Transmit Scale Weight
(This command can only be used when the scale mode has been set to the
Pounds Only Mode)
Scale Output Format: <STX>nnn.nnn<CR>
where:
<STX>
= ASCII STX
nnn.nnn = scale weight in pounds with decimal point
<CR>
= Carriage Return
If the scale weight is below zero, over capacity, in motion, or on center-of-zero, then the status word
is returned in place of the weight.
Z=>
Zero Scale Weight Command
(resets scale weight to zero)
A=>
Status Word Request
