Screw terminal assemblies
You can use screw terminal assemblies as an easy way to create matrix configurations without any
direct wiring. There are two screw terminal assemblies available for use with the Model 3732 card:
Model 3732-ST-C for column expansion, and Model 3732-ST-R for row expansion.
CAUTION
Important configuration information:
The Series 3700A mainframe does not support "hot swapping" of cards, which means there is a
possibility that the Model 3732 card may not be in the expected configuration when you turn on the
instrument power after removing a screw terminal that was connected when the instrument was last
turned on.
To ensure that you do not change your configuration, note that the Series 3700A instrument power
must be turned on AND the interlock must be connected and activated when you make configuration
changes. If the interlock is not activated when power is reapplied, the Model 3732 ID bits that define
the card’s configuration will not be read, and the default configuration will be what the configuration
was the last time when the power was turned on with the interlock activated.
NOTE
Additional information about screw terminal assemblies is available in the Series 3700A Screw
Terminal Assemblies Installation Instructions (part number PA-955), which can be downloaded from
