About this Chapter
This chapter will explain hardware configuration before installation in a
VXIbus mainframe. By attending to each of these configuration items, the

Configuring the VT1422A
There are several aspects to configuring the module before installing it in a
VXIbus mainframe. They are:
• Setting the Logical Address Switch . . . . . . . . . . . . . . . . . . . . page 24
• Installing Signal Conditioning Plug-Ons . . . . . . . . . . . . . . . . page 25
• Disabling the Input Protect Feature (Optional). . . . . . . . . . . . page 29
• Disabling Flash Memory Access (Optional). . . . . . . . . . . . . . page 29
For most applications, only the Logical Address switch needs to be
changed prior to installation. The other settings can be used as delivered.
Note Setting the VXIbus Interrupt Level: The VT1422A uses a default VXIbus
interrupt level of 1. The default setting is made at power-on and after an
*RST command. The interrupt level can be changed by executing the
DIAGnostic:INTerrupt[:LINe] command in the application program.
