Adding a Module
All modules available are one-slot, C-sized VXI modules to be plugged into a VXI mainframe.
Installing the module requires the following steps:
• Shutdown the HP 81200 System
• Select a mainframe slot.
• Set the VXI instrument logical address.
• Install the instrument in the mainframe.
• Build the new system
• Deskew the module
The first step to install the VXI instrument is to select a free slot in the VXI mainframe.
When you have selected a slot, enter the instrument model number, name, and serial number for the
instrument in the VXI Mainframe Overview table. You should maintain such a table for each
mainframe in order to keep track of the installed instruments.

Setting the VXI Instrument Logical Address
When you have selected the slot for the VXI instrument, the next step is to set the instrument logical
address (LADDR) as required. In general, you can use the factory-set (default) logical address.
If you need to set another logical address, use the following guidelines.
The logical address for each VXI instrument is set by the Logical Address (LADDR) switch on the
instrument. The logical address value is the sum of the values of the logical address switches set to the
closed position.
The following figure shows an example:
