Routing to the High-Voltage Backplane
Caution National Instruments installs safety covers on the HVAB connectors of the
NI 1357/1358/1359 kit. To use the HVAB connectors on the NI 1357/1358/1359 kit,
unscrew and flip back the covers. Always screw in the safety covers when the HVAB
connectors are not in use.
If you are using the NI SCXI-1127/1128/1129/1175, you can use the
NI 1357/1358/1359 kit to create a high-voltage analog backplane.
High-voltage backplanes share high-voltage signals among SCXI switches.
Unlike digital signals from the SH9MD-AUX cable that are routed to only
one switch, high-voltage signals are shared among all SCXI switches that
are connected to the backplane.
Configuring the SCXI Switch Module in MAX
Complete the following steps to configure the SCXI switch module:
Notes If you are using NI-DAQmx to configure SCXI switch modules cabled to an
NI SCXI-1357/1358/1359 kit, proceed directly to step 4 to create a new SCXI chassis.
If you are using NI-DAQmx to configure SCXI switch modules cabled to an
NI USB-1357/1358/1359 kit and the NI USB-1359 is auto-detected and the chassis is
auto-created in MAX, expand the NI-DAQmx Devices tab, right-click the chassis, and
choose Properties.The SCXI Chassis Configuration dialog box opens. The Modules tab
is selected by default. Proceed directly to step 5b to configure the switch module.
If you are using NI-DAQmx to configure an SCXI switch module cabled to an
NI USB-1357/1358/1359 kit and the kit was cabled before the chassis was powered on, the
chassis is not auto-detected and does not appear in MAX. Complete all of the following
steps to create your switch module and the chassis, and, subsequently, configure the switch
module.
1. Power on the chassis.
2. Right-click NI-DAQmx Devices in the configuration tree, and select
Create New NI-DAQmx Device. If you are using a remote RT target,
browse for your switch module under Remote Systems»Devices and

a. Select the switch controller (NI USB-1359 or
NI 4021/4060/407x) cabled to the communicating SCXI switch
module from the Chassis Communicator listbox. If MAX
detects only one communicating device, this device is selected as
the chassis communicator by default and the listbox is dimmed.
b. SCXI kits only—Select the module slot connected to the chassis
communicator from the Communicating SCXI Module Slot
listbox.
c. Enter the chassis address setting in the Chassis Address field.
Ensure that the setting you enter matches the address setting on
the SCXI chassis as shown in Figure 6.
d. Enable the auto-detect option to auto-detect installed SCXI switch
modules. If you do not auto-detect switch modules, MAX disables
the Communicating SCXI Module Slot listbox.
e. Click Save.
After creating a new chassis, the SCXI Chassis Configuration dialog
box opens as shown in Figure 8. The Modules tab is selected by
default.

5. Configure the SCXI switch module:
a. If you did not enable auto-detection of the switch module in
step 4d, select an SCXI switch module from the Module Array
listbox. Assign the switch module the slot number that matches
the physical slot location of the switch module in the chassis.
b. MAX assigns a default name to the SCXI switch module in the
Device Identifier textbox. The Device Identifier is the
resource name string in NI-SWITCH and the switch device
string in NI-DAQmx. To edit the default name, click the Device
Identifier textbox and enter a unique alphanumeric ID for the
switch module.
c. If you are using a connected accessory, such as a terminal block,
select it from the Accessory listbox.
6. Click Details to configure the switch module options.
The Details dialog box for the switch module configuration dialog box
opens. The Terminal Block/Topology tab is selected by default.
7. Configure the Details dialog box for an SCXI switch module:
Note During scanning, the NI SCXI-1127/1128 can connect to the HVAB. To configure
the switch module to automatically connect to the HVAB during scanning, enable the
optional checkbox in the Details dialog box.
a. Select the terminal block connected to the switch module from the
Terminal Block/Topology listbox.
b. Set a default topology from the Topology listbox.

NI 1357/1358/1359 Kit Installation Guide 10 ni.com
c. Select the Channels tab.
d. Designate source channels for the topology selected in the
Terminal Block/Topology tab. Notice that you can set different
source channels for each topology.
e. Designate reserved channels for routing. Notice that you can
reserve different channels for routing in each topology.
f. Click OK to accept the changes.
8. To configure additional SCXI switch modules, repeat steps 6 and 7.
9. If necessary, select the Chassis tab to modify chassis settings.
10. Click OK to accept and save the settings for the chassis.
Note You cannot save the chassis configuration until after you enter the switch module
information. A message at the top of the SCXI Chassis Configuration dialog box displays
the configuration status. If a warning appears in the message box, you can save the
configuration. If an error appears in the message box, you cannot save the configuration.
11. To test the configuration, right-click the chassis name listed under

Derating Modules that Share the HVAB
Caution As a safety precaution, modules that share a common HVAB must be derated to
their lowest common voltage rating, even if they do not connect signals to the backplane.
The following examples demonstrate how to derate switch modules:
Example 1
NI SCXI-1000 chassis
NI SCXI-1359 2-slot backplane adapter behind Slots 3 and 4
NI SCXI-1127 (300 V, CAT II) in Slot 4
NI SCXI-1129 (150 V, CAT I) in Slot 3
Both modules share the HVAB. Therefore, the NI SCXI-1127 must not
exceed the rating of the NI SCXI-1129 (150 V, CAT I).
Example 2
NI SCXI-1000 chassis
NI SCXI-1359 2-slot backplane adapter behind Slots 3 and 4
NI SCXI-1127 (300 V, CAT II) in Slot 4
NI SCXI-1129 (150 V, CAT I) in Slot 2
The NI SCXI-1127 does not share the HVAB with the NI SCXI-1129.
Therefore, the NI SCXI-1127 can operate at the full rating (300 V, CAT II).
Example 3
NI SCXI-1000 chassis
NI SCXI-1359 2-slot backplane adapter behind Slots 3 and 4
NI SCXI-1127 (300 V, CAT II) in Slot 4
NI SCXI-1190 (30 V, CAT I) in Slot 3
The NI SCXI-1190 does not have a HVAB connector. Therefore, the
NI SCXI-1127 can operate at the full rating (300 V, CAT II).
Environment
The NI 1357/1358/1359 kit is intended for indoor use only.
Operating temperature............................ 0 °C to 50 °C
