Configuring the VT1419A
There are several aspects to configuring the module before installing it in a VXIbus
mainframe. They are:
·
Setting the Logical Address Switch .....................page 15
·
Installing Signal Conditioning Plug-ons ..................page 16
·
Disabling the Input Protect Feature .....................page 21
·
Disabling Flash Memory Access .......................page 21
For most applications, only the Logical Address switch need be changed and the
SCPs installed in the mainframe prior to installation. The other settings can be
used as delivered.

NOTE Setting the VXIbus Interrupt Level: the VT1419A uses a default VXIbus interrupt
level of 1. The default setting is in effect at power-on and after a *RST command.
The interrupt level can be changed by executing the DIAGnostic:INTerrupt[:LINe]
command in the application program.
Setting the Logical
Address Switch
Follow the next figure and ignore any switch numbering printed on the Logical
Address switch. When installing more than one VT1419A in a single VXIbus
Mainframe, set each instrument to a different Logical Address.
