INTERFACING TO THE MODULE
The DMM portion of the VTI4101A uses a 15-pin D-Sub style connector for front panel
interfacing. There is a removable 2 A fuse for overcurrent protection. A mating connector is
provided with the unit upon shipment. The Counter/Timer portion of the device uses five SMB
style connectors for front panel interfacing.
In many ATE applications, a termination panel for the instrumentation is utilized. This termination
panel will have connectors that mate to the UUT or an intermediate test fixture. A termination
panel may take the form of an Interconnect Assembly (ICA) made by manufacturers such as
Virginia Panel or Macpanel. In either case, it is desirable to maintain the same I/O layout at the
panel to avoid costly redesign of test fixturing or UUT cable assemblies.
VXI Technology offers a couple of options that prevent the need for any interface panel to UUT
redesign as follows:
• wired funnel assemblies that mate directly to the VTI4101A front panel
• custom cabling between VTI4101A front panel and ICA/termination panel
For customers who plan on developing their own cabling between the VTI4101A and the
termination panel, this section provides a cross-reference pinout table between the VX4101A and
the VTI4101A in Table 12-1.
