Installing the NI PXIe-7822R
Caution To prevent damage to the device caused by ESD or contamination, handle
the device using the edges or the metal bracket.
1. Ensure the AC power source is connected to the chassis before installing the modules.
The AC power cord grounds the chassis and protects it from electrical damage while you
install the modules.
2. Power off the chassis.
3. Inspect the slot pins on the chassis backplane for any bends or damage prior to
installation. Do not install a module if the backplane is damaged.
4. Remove the black plastic connectors from all the captive screws on the module front
panel.
5. Identify a supported slot in the chassis. The following figure shows the symbols that
indicate the slot types.

Digital I/O
The NI PXIe-7822R provides connections for 128 digital input/output (DIO) channels.
Connectors 0 through 3 each contain 32 high-speed DIO channels that can run up to 80 MHz
signal frequencies. Each connector has selectable logic levels that you can configure as 1.2 V,
1.5 V, 1.8 V, 2.5 V, or 3.3 V. You can configure each channel as input or output.

2. LED
The DIO channels connect to the FPGA through protection circuitry, which has overvoltage
and undervoltage protection as well as overcurrent protection. Refer to the NI PXIe-7822R
Specifications for more information about the maximum voltage and current.
When the system powers on, the DIO channels are set as input low with pull-down resistors.
To set another power-on state, you can configure the NI PXIe-7822R to load a VI when the
system powers on. The VI can then set the DIO lines to any power-on state.
All the DIO channels on Connectors 0 through 3 are routed with a 50 Ω characteristic trace
impedance. Route all external circuitry with a similar impedance to ensure best signal quality.
NI recommends performing signal integrity measurements to test the affect of signal routing
with the cable and connection accessory for your application.
Installing Noise Suppression Ferrites
Caution To ensure the specified EMC performance, operate this product only with
shielded cables and accessories. Do not use unshielded cables or accessories unless
they are installed in a shielded enclosure with properly designed and shielded input/
output ports and connected to the product using a shielded cable. If unshielded
8| ni.com | NI PXIe-7822R Getting Started Guide
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
cables or accessories are not properly installed and shielded, the EMC specifications
for the product are no longer guaranteed.
Caution To ensure the specified EMC performance, install two (2) snap-on, ferrite
beads (777297-01) per connected I/O cable in accordance with the product
installation instructions.
Caution To ensure the specified EMC performance, the length of any cable
connected to the input port(s) must be no longer than 3 m (10 ft).
For each connected I/O cable, install two (2) snap-on, ferrite beads (777297-01), one on each
end of the cable, as close to the connector as practical.
Two (2) snap-on, ferrite beads (777297-01) are included in ach of the following recommended
cable kits:
• Shielded R Series High Speed Digital Cable, 1m (156166-01)
• Shielded R Series High Speed Digital Cable, 2m (156166-02)
For user-supplied cables, the ferrite beads can be ordered directly from NI by visiting ni.com/
info and entering RDIO2FERRITE.
