© National Instruments | 1-7NI cDAQ-9181/9184/9188/9191 User ManualNote If you use shielded cabling to connect to a C Series module with a plasticconnector, you must attach the cable shield to the chassis grounding terminal using1.31 mm2 (16 AWG) or larger wire. Use shorter wire for better EMC performance.Figure 1-4. Ring Lug Attached to Chassis Ground Terminal8. Make sure that no signals are connected to the C Series module.9. Align the C Series module with the cDAQ chassis slot.10. Squeeze both C Series module latches, insert the module into the module slot, and pressuntil both latches lock the module in place.11. Wire the C Series module as indicated in the C Series module documentation.Note Connect I/O cable shields to the chassis grounding screw, shown inFigure 1-4, unless otherwise specified in the C Series module documentation. Referto the Chassis Grounding Screw section for more information about making thisconnection.12. Connect one end of the Ethernet cable to the Ethernet port on the chassis, and the other enddirectly to your computer or any network connection on the same subnet as your computer.Refer to the Ethernet Cabling section for information about the Ethernet cable.13. (cDAQ-9191) If you want to connect the cDAQ-9191 to a wireless network, attach thesupplied antenna.14. Power the chassis using the included power adapter or other 9 V DC to 30 V DC powersource. The cDAQ chassis requires an external power supply that meets the specificationslisted in the specifications document for your cDAQ chassis. For information about wiringyour external power source, refer to the Wiring Power to the cDAQ Chassis section
