STEP 2:
6.0 mm
Mounting the NI UES-3880 on the wall requires 4 screws.
Use the switch, with wall mount plates attached, as a guide
to mark the correct locations of the 4 screws. The heads of
the screws should be less than 6.0 mm in diameter, and the
shafts should be less than 3.5 mm in diameter, as shown in
the figure at the right.
3.5 mm
NOTE Before tightening the screws into the wall, make sure the screw head
and shank size are suitable by inserting the screw into one of the
keyhole-shaped apertures of the Wall Mounting Plates.
Do not screw the screws in all the way—leave about 2 mm to allow room for
sliding the wall mount panel between the wall and the screws.

downwards, as indicated. Tighten
the four screws for added stability.
Wiring Requirements
WARNING
Do not disconnect modules or wires unless the power supply has
been switched off or the area is known to be non-hazardous. The
devices may only be connected to the supply voltage shown on
the type plate.
The devices are designed for operation with a Safety Extra-Low
Voltage. Thus, they may only be connected to the supply voltage
connections and to the signal contact with the Safety Extra-Low
Voltages (SELV) in compliance with IEC950/ EN60950/
VDE0805.
WARNING
Substitution of components may impair suitability for Class I,
Division 2, and Zone 2. These devices must be supplied by an
SELV source as defined in Low Voltage Directive 73/23/EEC
and 93/68/EEC.
WARNING
This unit is a built-in type. When the unit is installed in another
piece of equipment, the equipment enclosing the unit must
comply with fire enclosure regulation IEC 60950/EN60950 (or
similar regulation).
WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your Switch.
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.

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.
y
y
NOTE: Do not run signal or communications 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 separated.
y
y
It is strongly advised that you label wiring to all devices in the system when
necessary.
Grounding the Switch
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
ground screw to the grounding surface prior to connecting devices.
ATTENTION
This product is intended to be mounted to a well-grounded
mounting surface, such as a metal panel.
Wiring the Alarm Contact
The Alarm Contact consists of the two middle contacts of the terminal block on
the NI UES-3880’s top panel. You may refer to the next section for detailed
instructions on how to connect the wires to the terminal block connector, and
how to attach the terminal block connector to the terminal block receptor. In
this section, we explain the meaning of the two contacts used to connect the
Alarm Contact.
FAULT: The two middle contacts of the
6-contact terminal block connector are used to

STEP 3: Insert the plastic terminal block
connector prongs into the terminal block
receptor, which is located on the NI UES-3880’s
top panel.
ATTENTION
Before connecting the NI UES-3880 to the DC power inputs,
make sure the DC power source voltage is stable.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the NI UES-3880’s front panel are used
to connect to Ethernet-enabled devices.
Below we show pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports, and also show cable wiring diagrams for
straight-through and cross-over Ethernet cables.

Redundant Power Inputs
Both power inputs can be connected simultaneously to live DC power sources.
If one power source fails, the other live source acts as a backup, and
automatically supplies all of the NI UES-3880’s power needs.
Alarm Contact
The NI UES-3880 has one Alarm Contact located on the top panel. For detailed
instructions on how to connect the Alarm Contact power wires to the two
middle contacts of the 6-contact terminal block connector, see the Wiring the
Alarm Contact section. A typical scenario would be to connect the Fault circuit
to a warning light located in the control room. The light can be set up to switch
on when a fault is detected.
The Alarm Contact has two terminals that form a Fault circuit for connecting to
an alarm system. The two wires attached to the Fault contacts form an open
circuit when (1) the NI UES-3880 has lost power from one of the DC power
inputs, or (2) one of the ports for which the corresponding PORT ALARM DIP
Switch is set to ON is not properly connected.
If neither of these two conditions occurs, the Fault circuit will be closed.

Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the NI UES-3880’s
10/100BaseTX ports to any kind of Ethernet device, without needing to pay
attention to the type of Ethernet cable being used for the connection. This
means that you can use either a straight-through cable or cross-over cable to
connect the NI UES-3880 to Ethernet devices.
Dual Speed Functionality and
Switching
The NI UES-3880’s 10/100 Mbps switched RJ45 port auto-negotiates with the
connected device for the fastest data transmission rate supported by both
devices. The NI UES-3880 is a plug-and-play devices, so that software
configuration is not required at installation, or during maintenance. The
half/full duplex mode for the switched RJ45 ports is user dependent and
changes (by auto-negotiation) to full or half duplex, depending on which
transmission speed is supported by the attached device.
Switching, Filtering, and Forwarding
Each time a packet arrives at one of the switched ports, a decision is made to
either filter or forward the packet. Packets with source and destination
addresses belonging to the same port segment will be filtered, constraining
those packets to one port, and relieving the rest of the network from the need to
process them. A packet with destination address on another port segment will
be forwarded to the appropriate port, and will not be sent to the other ports

where it is not needed. Packets that are used in maintaining the operation of the
network (such as the occasional multi-cast packet) are forwarded to all ports.
The NI UES-3880 operates in the store-and-forward switching mode, which
eliminates bad packets and enables peak performance to be achieved when
there is heavy traffic on the network.
Switching and Address Learning
The NI UES-3880 has an address table that can hold up to 1K node addresses,
which makes it suitable for use with large networks. The address tables are
self-learning, so that as nodes are added or removed, or moved from one
segment to another, the NI UES-3880 automatically keeps up with new node
locations. An address-aging algorithm causes the least-used addresses to be
deleted in favor of newer, more frequently used addresses. To reset the address
buffer, power down the unit and then power it back up.
Auto-Negotiation and Speed Sensing
The NI UES-3880 is a RJ45 Ethernet ports independently support
auto-negotiation for speeds in the 10BaseT and 100BaseTX modes, with
operation according to the IEEE 802.3u standard. This means that some nodes
could be operating at 10 Mbps, while at the same time, other nodes are
operating at 100 Mbps.
Auto-negotiation takes place when an RJ45 cable connection is made, and then
each time a LINK is enabled. The NI UES-3880 advertises its capability for
using either 10 Mbps or 100 Mbps transmission speeds, with the device at the
other end of the cable expected to similarly advertise. Depending on what type
of device is connected, this will result in agreement to operate at a speed of
either 10 Mbps or 100 Mbps.
If the NI UES-3880 RJ45 Ethernet port is connected to a non-negotiating
device, it will default to 10 Mbps speed and half-duplex mode, as required by
the IEEE 802.3u standard.
