Commander/Servant
Hierarchies when
using a Command
Module
When you have an EPC7, Command Module, and Agilent register-based
instruments to be accessed via GPIB in the same system, you must change
the commander/servant hierarchy and interrupt mapping so that selected
instruments report to the Command Module instead of the EPC7. Changing
the commander/servant hierarchy involves the following:
• Verifying instruments in the database
• Assigning VXI device names
• Assigning Commander/Servant Hierarchy
• Assigning interrupt lines
Each procedure is described in following sections and can be run by
opening the VXI Configurator icon in the EPConnect Program Group. See
the EPC7 documentation for additional information on these procedures.
Verifying Instruments in the Database
1. From Windows, select the VXI Configurator icon.
2. Select Database and scroll to Models.
3. Verify that your instruments are listed in the database. If you need
to add an instrument, fill in the data and select the Add button. The
following is an example of adding an Agilent E1406A :
– Select Manufacturer - Hewlett-Pack
– Enter Model - Agilent E1406A
– Enter Model number - 276 (This is the model code printed on
side of the instrument.)
– Select the Add button
Repeat this step for each instrument that needs to be added to the
database.
4. Select OK to end.
Assigning VXI Device Names
1. From the VXI Configurator, select Devices and scroll to VXI.
2. Each instrument in your system needs to have a device name
assigned. The following in an example of assigning a name to the
E1406A Command Module:
– Enter a device name in the Name field - Cmdmod
– Select the device from the Manufacturer/Model menu -
Hewlett-Pack Agilent E1406 276
– Clear the Location and Logical address check boxes.
