Connecting the Hardware

This section describes how to connect NPort 5400 to serial devices for first time testing purposes. We cover Wiring Requirements, Connecting the Power, Grounding NPort 5400, Connecting to the Network, and Connecting to a Serial Device.

Wiring Requirements

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your NPort 5400.

Wiring Caution!

Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size.

If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.

Temperature Caution!

Please take care when handling NPort 5400. When plugged in, NPort 5420/5430/5430I’s internal components generate heat, and consequently the casing may feel hot to the touch.

You should also pay attention to the following points:

Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.

NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.

You can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.

Keep input wiring and output wiring separate.

Where necessary, it is strongly advised that you label wiring to all devices in the system.

Connecting the Power

Connect the 12-48 VDC power line with NPort 5400’s terminal block. If the power is properly supplied, the “Ready” LED will show a solid red color until the system is ready, at which time the “Ready” LED will change to a green color.
