Interface Operation
67
Notes:
1)
These selections assume the use of a single controller. In configurations where a
second controller exists these may be altered, other settings have not been fully
tested
by
Vitrek.
2)
These instruments do not currently use the SRQ and Serial Poll capabilities of the
IEEE488 bus. This setting will be dependent on other instruments, thus does not
affect your 6000 instrument.
3)
Timings of longer than this are also valid. The 350nS selection has been tested on
shorter cable lengths by
Vitrek.
and may be used. However, in
normal operation there
is little overall performance gain by using it with these
instruments. A shorter time
may be selected, if, other high-speed devices exist in the
system.
4)
These instruments do not use the IEEE488.2 specifications, thus this setting has
no
affect on these instruments if you have otherwise ensured that no IEEE488.2 type
transfers take place with these instruments. If all other devices also do not use the
IEEE488.2 type transfers, then this setting should be set to “
NO”
to ensure
compatibility.
5)
Although these settings have no affect on these instruments, ensure that no
hardware conflicts exist with other installed devices in the computer. The settings
shown above are highly recommended, as the probability of conflict is lowest with
these settings.
Interrogating the Data
With either interface, you may interrogate the various data held by the instrument.
Reading Data
Interrogation is achieved by sending a “
DATA READ
” command string that defines
the data is to be interrogated, and then by reading that data from the instrument. Up
to 1000 characters may be read from the instrument as a result of sending a
DATA
READ
command. Refer to
Command Set
on page 71.
In the RS232 interface, this data is automatically transmitted from the instrument to
the controller, the instrument will then wait for a further
DATA READ
command
before sending further data.
