6.2 Status Messages

Two EDP commands, P and ZZ, can be used to provide status about the 

Tracer AV

. These commands are described in the 

following sections.

6.2.1 Using the P EDP Command

The P EDP command returns the current displayed weight value to the EDP port, along with the units identifier. If the indicator 

is in an underrange or overload condition, the weight value is replaced with

 &&&&&&

 (overload) or 

::::::

 (underrange).

6.2.2 Using the ZZ EDP Command

The ZZ EDP command can be used to remotely query which annunciators are currently displayed. 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 6-3). If more than one 

annunciator is lit, the second number returned is the sum of the values representing the active annunciators.
Example: If the annunciator status value returned on the ZZ command is 145, the gross, standstill, and lb annunciators are lit. 

145 represents the sum of the values for the standstill annunciator (128), gross mode annunciator (16), and the lb/primary units 

annunciator (1).
