Bus Addresses
When an IEEE 488 system comprises several instruments, a unique ‘Address’ is assigned
to each to enable the controller to communicate with them individually.
Only one address is required for the 9100. The application program adds information to
it to define ‘talk’ or ‘listen’. The method of setting the address, and the point at which the
user-initiated address is recognized by the 9100, is given in Sub-Section 6.4.1.
The 9100 has a single primary address, which can be set by the user to any value within
the range from 0 to 30 inclusive. It cannot be made to respond to any address outside this
range. Secondary addressing is not available.
6.3.1.6
Limited Access
The 9100 has five main modes, which are described briefly in Volume 1 of this Handbook,
Section 1, Sub-section 1.2.2. Remote operation is available only subject to the following
limitations:
•
Procedure Mode
When the 9100 is in Procedure Mode, it is driven essentially from the front panel.
Remote Operation will not be allowed in this mode.
N.B.
The 9100 can be powered up in either Manual mode or Procedure mode, as set
locally in Configuration mode.
•
Manual Mode
Remote operation is available for each Manual mode function, but for ease of
programming, some remote commands do not mirror front panel operations exactly.
•
Configuration Mode
Remote operation is not available, and configuration commands have not been
included in the SCPI command set for the 9100.
•
Calibration Mode
Remote operation is available, but refer to Sub-section 6.6.2 for details of entry
protection.
•
Test Mode
Remote operation is not available, but the 'Full' selftest can be initiated by a SCPI
command. The 9100 will give a straight Pass/Fail response, but to investigate further,
it will be necessary to re-run the test in Test mode from the front panel.
