9. Command : STAT? <EOS>
Description: Read Status Query.
Function: This command reads the status of various events occurred in the
system. The definition of events is given below
B0: Over voltage Trip
B1: Over Temperature Trip
B2: Power On event (Sets when unit is turn ON. The bit gets cleared after the
quarry.)
B3: Internal Failure
B4: Always 1 (THIS STATUS BIT MAY BE CHANGED IN FUTURE)
B5: Always 1 (THIS STATUS BIT MAY BE CHANGED IN FUTURE)
B6: Command Error (Sets if invalid command received by unit. The bit gets
cleared after the quarry.)
B7: Always 0
The response to the quarry is single character followed by EOS.
For example after power On condition the response to the quarry
STAT?
Will be
4<EOS>. If Over voltage trip condition occurs then the response will be
1<EOS>.
6.4 IEEE-488 OPERATION:
The IEEE-488 (GPIB) interface option allows the instrument to connect and
form part of an Automated Test System. The instruments are instructed over a
Parallel Data Bus, so that their facilities can be selected remotely. The ADDRESS
concept, Parallel Data Bus and Handshaking are the main advantages over the
RS23C interface, by which at a time more than one instrument (up to 31 instru-
ments) can be connected on the IEEE-488 bus and only the Addressed instrument
can be made to LISTEN or TALK without losing any data. The communication will
be faster because of parallel data transfer.
The IEEE-488 bus has standard 24 PIN flat cable, in which each line is
dedicated to a special BUS activity. The CONTROLLER can send messages or
receive responses from all or any one instrument by proper BUS activation and
handshaking.
