Chapter 1 Getting Started with the cDAQ Chassis

Ethernet Port

The cDAQ-9181/9191 chassis has one dual-speed RJ-45 Ethernet port, as shown in Figure 1-1.
The cDAQ-9184/9188 chassis has one tri-speed RJ-45 Ethernet port, as shown in Figure 1-2
or 1-3. You can use a shielded straight through Category 5 Ethernet cable to connect one end to
the RJ-45 Ethernet port on the chassis, and the other end directly to your computer or any
network connection on the same subnet as your computer.
