8.2.2 Using the ZZ EDP Command
The ZZ EDP command can be used to remotely query which annunciators are currently displayed on the
indicator front panel. The ZZ command returns the currently displayed weight and a decimal number
representing the LED annunciators currently lit. The format of the returned data is:
wwwwww uu zzz
where wwwwww uu is the current displayed weight and units, zzz is the annunciator status value (see Table 8-3). If
more than one annunciator is lit, the second number returned is the sum of the values representing the active
annunciators.
For example, if the annunciator status value returned on the ZZ command is 148, the gross, standstill, and lb
annunciators are lit: 148 represents the sum of the values for the standstill annunciator (16), gross mode
annunciator (128), and the lb/primary units annunciator (4).
8.3 Continuous Output (Stream) Format
Figure 8-1 shows the continuous output format sent to the
320IS Plus
EDP or printer port when the STREAM
parameter (SERIAL menu) is set to either EDP or PRN.
