8.1 Error Messages
The
320IS Plus
indicator provides a number of error messages. When an error occurs, the message is shown on
the indicator LED display. Error conditions can also be checked remotely by using the XE EDP command as
described in Section 8.1.2.
8.1.1 Displayed Error Messages
The
320IS Plus
provides a number of front panel error messages to assist in problem diagnosis. Table 8-1 lists
these messages and their meanings.
8.1.2 Using the XE EDP Command
The XE EDP command can be used to remotely query the 320IS Plus 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 8-2.
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 8-2 to indicate whether the
test for the error condition was run. For example, the value
yyyyy
= 63487 represents the decimal equivalent of the
binary value 1111 0111 1111 1111. Using the bit assignments in Table 8-2, this value indicates all tests were run.
