Switch Accessories and Cables
Switch Controller (see Figure 1)
NI 4021 switch controllers provides complete control of an SCXI-based switching
system. These accessories are the ideal low-cost control solution when the
switching modules are used with third-party instruments or to route signals to
measurement devices other than the NI 4060 or PXI-4070 DMMs. NI 4021
requires no additional software.

High-Voltage Backplane Assemblies
For the SCXI-1127, SCXI-1128, and SCXI-1129 multiplexer/matrix modules. The
SCXI-1357 consists of a 4-slot high-voltage backplane, two cables for routing
analog and digital signals to an external scanning DMM, and two analog bus plugs
for connecting the backplane components. The SCXI-1358 is identical to the
SCXI-1357, except it is for a 12-slot SCXI chassis. To add more chassis to your high-
voltage backplane configuration, purchase one add-on kit for each chassis added.
You can intermix 4 and 12-slot chassis.

SCXI Communication Adapter Kits
These kits include a backplane adapter that connects the digital control lines of
the NI 4060 and PXI-4070 DMMs and NI 4021 switch controller to the switch
modules. The SCXI-1359 includes an SCXI-1359 backplane and an SH9MD-AUX
cable. The SCXI-1362 Kit includes an SCXI-1362 backplane and an SH9MD-AUX
cable. During multichassis expansion the SH9MD-AUX cable is used to connect
two SCXI-1362 backplanes.
