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 DAQ communicating 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
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.
4. Repeat steps 1 through 3 for each SCXI chassis in the system, excluding the last SCXI chassis in
the chain.
