Getting Started with the cDAQ Chassis
Note
If you use shielded cabling to connect to a C Series I/O module with a plastic
connector, you must attach the cable shield to the chassis grounding terminal using
1.31 mm
2
(16 AWG) or larger wire. Use shorter wire for better EMC performance.
Note
Make sure that no I/O-side power is connected to the I/O module. If the
chassis is in a nonhazardous location, the chassis power can be on when you install
I/O modules.
7.
Align the I/O module with a cDAQ chassis slot. The module slots are labeled 1 to 8, left to
right.
8.
Squeeze the latches and insert the I/O module into the module slot, and press firmly on the
connector side of the I/O module until the latches lock the I/O module into place.
Repeat these steps to install additional I/O modules.
9.
Verify that the DISABLE RT DIP switch is in the OFF position so that the chassis will boot
into LabVIEW Real-Time. Refer to the
section for more information about
the DISABLE RT DIP switch.

10. Wire your external power source as outlined in the
Wiring Power to the cDAQ Chassis
section. The cDAQ chassis requires an external power supply that meets the specifications
listed in the specifications document for your cDAQ chassis.
11. Turn on the external power supply.
12. Connect RJ-45 Ethernet port 1 on the cDAQ chassis to the same Ethernet network as the
host computer with a shielded straight through Category 5 (CAT-5) or better shielded,
twisted-pair Ethernet cable.
Caution
To prevent data loss and to maintain the integrity of your Ethernet
installation, do
not
use a cable longer than 100 m.
If you need to build your own cable, refer to the
section for information
about Ethernet cable wiring connections.
13. Press the power button on the front panel of the cDAQ chassis.
When the cDAQ chassis powers on, the Power LED lights and the controller runs a
power-on self test (POST). When the POST is complete, the operating system is loaded.
The cDAQ chassis attempts to initiate a DHCP network connection at powerup. If the
cDAQ chassis is unable to obtain an IP address, it connects to the network with a link-local
