Connecting the Hardware
This section describes how to connect NPort W2250/2150 to serial devices for first time testing
purposes. We cover Wiring Requirements, Connecting the Power, Connecting to the Network,
Connecting to a Serial Device, and LED Indicators.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your device.
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!
Be careful when handling the device. When plugged in, the device’s internal components
generate heat, and consequently the casing may feel hot to the touch.
You should also pay attention to the following items:
y 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.
y 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.
y Keep input wiring and output wiring separate.
y Where necessary, it is advisable to label the wiring to all devices in the system.
Connecting to the Network
Connect one end of the Ethernet cable to NPort W2250/2150’s 10/100M Ethernet port and the
other end of the cable to the Ethernet network. If the cable is properly connected, NPort
W2250/2150 will indicate a valid connection to the Ethernet in the following ways:
y The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet
network.
y The Ethernet LED maintains a solid orange color when connected to a 10 Mbps Ethernet
network.
y The Ethernet LED will flash when Ethernet packets are being transmitted or received.
