9.1.2 Using the XE EDP Command
The XE EDP command can be used to remotely query the 480 for the error conditions shown on the front panel.
The XE command returns two 5 digit numbers in the format:
xxxxx yyyyy
where xxxxx contains a decimal representation of any existing error conditions as described in Table 9-2.
If more than one error condition exists, the number returned is the sum of the values representing the error
conditions. For example, if the XE command returns the number 1040, this value represents the sum of an A/D
reference error (1024) and an A/D calibration checksum error (16).
The second number returned ( yyyyy ) uses the same bit assignments as shown in Table 9-2 to indicate whether the
test for the error condition was run. For example, the value yyyyy = 50815 represents the decimal equivalent of the
binary value 1100 0110 0111 1111. Using the bit assignments in Table 9-2, this value indicates all tests were run.

9.2 Status Messages
Two EDP commands, P and ZZ, can be used to provide status about the indicator. These commands are described
in the following sections.
9.2.1 Using the P EDP Command
The P EDP command returns the current displayed weight value, along with the units identifier. If the indicator is
in an underrange or overload condition, the weight value is replaced with
&&&&&& (overload) or :::::: (underrange).
9.2.2 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, and zzz is the annunciator status value (see Table 9-3).
If more than one annunciator is lit, ZZZ is the sum of the values representing the active annunciators.
