IEEE-488 interface
IMPORTANT
The IEEE-488 function must be selected in the SETUP menu page 2 on the line
INTERFACE : IEEE = 05
The test units of the XS series could be equipped with a IEEE-488 interface. This option makes
possible the integration of any unit of the series in an automatic measurement or test system in
manufacturing or incoming inspection department.
This interface is accessible through a connector provided on the rear panel.
Syntax rules
The end of a message must be the LF character (hexadecimal 0A, decimal 10).
The separators inside a message are ; or :
The commands can be sent either in small letters or in capital letters.
The maximum number of commands by message is
15
.
NOTE :be careful not to put together standardised commands with other ones.
When a event like
transmission error,end of test, safety loop open
, ...,occurs during the measurement
, the controller could be informed by a SRQ.
To activate this function, you must send a SRQ command just after the initialization of the unit.
On event, you could read the internal registers of the IEEE controler ( STB,SRE,...) to get more
precise reasons why.
If the message is not recognized by the unit, the error message <DIALOG ERROR : 1> is displayed
If the code is out of context, the error message <DIALOG ERROR: 2> is displayed
(special code for a function when the function was not selected or numerical value out of range)
IEEE-488-1 Fonctions availables
SH1,AH1,T6,L4,SR1,RL1,PP0,DC1,DT0,C0
List of the IEEE-488 commands
The syntax of the commands complies with the IEEE488-2 standard (1992 revision).
IEEE488-2 numerical formats :
Format NR1 : ±<digit>...<digit>
Format NR2 : +/-<digit>...<digit>.<digit>...<digit>
Format NR3 : ±<digit>...<digit>.<digit>...<digit>E+/-<digit>..<digit>
Note : Codes in brackets are expensed codes which can be understood by the unit
