Configuring ParBERT Starting ParBERT for the First Time
Agilent 81250 ParBERT Installation Guide, February 2002 81
2 Click Select Interfaces... 
The VISA Interfaces available for use window opens with the 
available I/O interfaces.
3 Select the I/O interface you will be using. The default is VXI0. 
If you are using an external controller connected to more than one 
IEEE 1394 PC to VXI module, you have to select the interfaces you 
wish to control.
NOTE If you are upgrading from a previous software version, you must make 
sure you use the same interface type as before. This ensures that existing 
programs will still run after the upgrade.
Build Systems
When you click Build Systems in the Agilent 81250 Configuration Tool 
dialog box, the Configuration Tool checks which hardware is installed, 
how the clock groups are configured, and creates the new configuration 
files 
dvtsys.txt
 and 
dvtits.txt
. The current configuration files are 
backed up (renamed 
*.bak
).
CAUTION If you execute Build Systems twice, the backup configuration files are 
overwritten.
The default generated system name is DSRA. If the mainframe contains 
more than one system, as shown in the figure below, additional systems 
(DSRB, DSRC, ...) are automatically set up.
