Normal Weighing Mode Operations 35
5.6.2 Demand Mode versus Continuous Data Output
Demand mode is used to interface with printers and
requires a manual Print command from the front panel
to initiate the output data. To comply with
legal-for-trade regulations, demand output data is
inhibited during the following conditions:
• Scale in motion
• Positive overload
•Negative overload
•Negative gross weight displayed
•Unit in display check mode
NOTE: In legal-for-trade applications, the Motion
Detection Parameter (Parameter 9) must be turned ON.
In demand mode, the operator may choose to print
Gross/Tare/Net when in net mode. If the serial port is
set to Print on Demand mode, the format is:
<STX><POL><DATA><SP><LB/KG><SP><GR/NT>
<SP><CR><LF>
General Continuous Mode Output Data Format
Continuous mode is used to interface to computers,
scoreboards, and other remote devices requiring
constant data updating. Continuous mode
transmission occurs at the end of each display update.
<STX><POL><DATA><L/K><G/N><STAT><CR><LF>
Downloading/Recall Commands
The format for fixed tare data entry (see Table 5-5) is:
<FE>(XXXXXX)<CR>
The format for fixed tare data recall (see Table 5-5) is:
<FR>(XXXXXX)<CR>

• Response data (xxxxxx) is six characters with

to with an echo of valid portion and the letter
I indicating the invalid portion.
