13.2 Using the HARDWARE Command

The HARDWARE serial command can be used to
verify that installed option cards are recognized by the
system. The HARDWARE command returns a
single-digit card code, representing the card installed:
Code
0
4
8
Table 13-2. HARDWARE Command Option Card Type
Codes
If an installed card is not recognized (HARDWARE
command returns code of 0), ensure that the card is
seated properly. Reinstall the card, if necessary, then
cycle the power to read the configuration again. If the
card is still not recognized, you may need to try a
different option card.

13.3 Using the XE EDP Command

The XE EDP command can be used to remotely query
the 520 for the error conditions shown on the front
panel. The XE command returns a decimal number
representing any existing error conditions.
If more than one error condition exists, the number
returned is the sum of the values representing the error
conditions (see Table 13-3). 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).

13.4 Status Messages

Two EDP commands, P and ZZ, can be used to
provide status about the indicator.
• The P EDP command returns whatever is
currently shown in the indicator's primary
display area.
• The ZZ EDP command returns whatever is
currently shown in both the primary and
secondary displays. Depending on the type of
device used to receive data from the indicator,
the standstill and center of zero symbols may
be shown as spaces or as special characters.
The ZZ command returns information in the
following format:
PPPPPPP uu ssssssssssssssss
where:
• is the information shown on
PPPPPPP
the primary display
• is the 2-digit units annunciator
uu

If the indicator is in an underrange or overload
condition, the weight value is replaced with
(overload) or :::::: (underrange).
