Connecting the Chassis to a Network

Connect the chassis to an Ethernet network using Ethernet port 1 on the front panel. Use a standard Category 5 (CAT-5) or better Ethernet cable to connect the chassis to an Ethernet hub or a computer.

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 are using 100 Mbps Ethernet, National

Instruments recommends using a CAT-5 or better shielded twisted-pair Ethernet cable.

If you need to build your own cable, refer to the

Cabling

section for more information about Ethernet cable wiring connections.

Note You will configure the IP settings as described in the

Configuring IP Settings

section, after connecting power and powering the chassis on.

The host computer communicates with the chassis over a standard Ethernet connection. If the host computer is on a network, you must configure the chassis on the same subnet as the host computer. If neither the host computer nor the chassis is connected to a network, you can connect the two directly using a crossover cable.

If you want to use the chassis on a subnet other than the one the host computer is on, first connect the chassis on the same subnet as the host computer. Use DHCP to assign an IP address or reassign a static IP address for the subnet where you want it to be and physically move it to the other subnet.

Wiring Power to the Chassis

The NI 9148 requires an external power supply that meets the

specifications in the Power Requirements

section. The NI 9148 filters and regulates the supplied power and provides power for all of the I/O modules.

© National Instruments Corporation 9 NI 9148 Operating Instructions and Specifications

The NI 9148 has one layer of reverse-voltage protection. Complete the following steps to connect a power supply to the chassis.

1.

Connect the positive lead of the power supply to the V terminal of the

COMBICON connector shipped with the NI 9148, and tighten the

terminal screw. Figure 11 shows the terminal screws, which secure the

wires in the screw terminals, and the connector screws, which secure the power connector on the controller.
