9.2 Using the XE EDP Command
The XE EDP command can be used to remotely query
the CW-90/CW-90X for the error conditions shown on
the front panel. The XE command returns a 5-digit
number 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).

9.3 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.
9.3.1 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).
9.3.2 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 9-3).
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).
