If all modules are in parallel mode, attach a cable adapter to each module. The following
modules can run in parallel mode:
2.
Insert the 50-pin female connection on the rear of the cable adapter into the 50-pin male connector
on the rear of the appropriate SCXI module.
Caution
Do
not
force the adapter if there is resistance. Forcing the adapter can bend pins.
3.
Fasten the adapter to the rear of the SCXI chassis with the screws provided with the SCXI-1349.
Figure 10.
Installing the Cable Adapter
Multichassis System
The SCXI-1346 covers the rear connector of two modules. When viewing the chassis from the rear, the
module to the right of the module directly connected to the SCXI-1346 cannot have an external cable
inserted into its rear 50-pin connector.
SCXI-1000 chassis through revision D do not have address jumpers or switches and respond to any
address, but you cannot use them in multichassis systems. Revision E chassis use jumpers on Slot 0 for
chassis addressing. Revision F and later chassis use a DIP switch for chassis addressing.
SCXI-1000DC chassis through revision C do not have address jumpers or switches and respond to any
address, but you cannot use them in multichassis systems. Revision D and later chassis use jumpers on
Slot 0 for chassis addressing.
SCXI-1001 chassis through revision D use jumpers on Slot 0 for chassis addressing. Revision E and later
chassis use a DIP switch for chassis addressing.
To connect the multichassis system, you must use one SCXI-1346 multichassis adapter for every chassis
in the chain except the chassis furthest from the E Series or M Series DAQ device. The last chassis uses
the SCXI-1349 cable adapter.
1.
Identify the appropriate SCXI module to connect to the cable adapter. Refer to step 1 of the
previous
section to determine the appropriate module.
2.
Insert the 50-pin female connection on the rear of the cable adapter into the 50-pin male connector
on the rear of the appropriate SCXI module.
3.
Fasten the adapter to the rear of the SCXI chassis with the screws provided with the SCXI-1346.
