The SCXI-1331 terminal block has screw terminal connections for all
channels, bank commons, analog bus, and trigger signals. You can use
this module for multiplexer switching applications. The terminal block
has a temperature sensor that is used for thermocouple cold-junction
compensation.

The SCXI-1332 terminal block converts the switch card to a 4
× 8,
2-wire matrix configuration. This terminal block creates the matrix
configuration by connecting channels (0, 8, 16, 24), (1, 9, 17, 25),
(7, 15, 23, 31).

Use the high-voltage matrix expansion cables to interconnect several
SCXI-1332s to build matrices larger than 4

Use the 1-slot, 2-slot, and 8-slot HVAB-backplane adapters to connect
the HVAB of the SCXI-1127/1128 to the DMM. You can also use them
to establish HVAB connections across multiple SCXI-1127/1128
modules or SCXI chassis. The 2-slot and 8-slot HVAB-backplane
adapters have four connectors on the external side—two HVAB
connectors, one digital input in (AUXIN) connector, and one digital
input out (AUXOUT) connector. The 1-slot SCXI-1357 has only
HVAB connectors. The purpose of the AUXIN connector is to
cable the digital communication signals from the DMM to the
SCXI-1127/1128 and finally to the SCXI chassis backplane as shown
in Figure 1-9,

Use a SH9MD-9MD cable to connect digital communication lines of
the NI-DMM to the SCXI-1127 AUXOUT connector. You can also use
this cable to carry signals to the next chassis.
