NE-4000T Series User’s Manual Getting Started
Wiring Requirements
You should heed the following common safety precautions before proceeding with the installation
of any electronic device:
yUse 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.
yUse 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.
yKeep input wiring and output wiring separate.
yIt is advisable to label the wiring to all devices in the system.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your NE-4000T-ST.
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 NE-4000T-ST. When plugged in, NE-4000T-ST’s internal
components generate heat, and consequently the board may feel hot to the touch.
Plugging NE-4000T into NE-4000T-ST
Before you connect NE-4000T-ST to the power supply, network, and serial device, you first need
to plug the NE-4000T module into the NE-4000T-ST board. Both the module and board are
clearly marked with white triangles that indicate how to position NE-4000T before plugging it in.
In the center of NE-4000T-ST, there is a square with one white inverted triangle (shown as black
in the figure) on one of its sides, and 2 rows of female sockets on the other two sides. The
NE-4000T board also has a white inverted triangle (shown as black in the figure) on one of its
sides. When plugging your NE-4000T into the NE-4000T-ST board, make sure these 2 white
inverted triangles are facing the same direction, as shown in the figure.
3-2

NE-4000T Series User’s Manual Getting Started
Connecting the Power
Connect the 12-30 VDC power line to NE-4000T-ST’s terminal block. If the power cord is
properly connected, the “POWER” LED will illuminate in red. When the system boots up and is
ready to go, the “Ready” LED will illuminate in green.
Connecting to the Network
Connect one end of the Ethernet Cable to NE-4000T-ST’s Ethernet port and the other end of the
cable to the Ethernet network. If the cable is properly connected, NE-4000T-ST will indicate a
valid connection to the Ethernet in the following ways:
yThe Link LED will maintain a solid green color when connected to a 10 Mbps Ethernet
network.
yThe Link LED will flicker when Ethernet packets are being transmitted or received.
Connecting to a Serial Device
Use a serial data cable to connect a serial device to the NE-4000T-ST board when testing and
developing applications. NE-4000T-ST’s serial port also serves as a serial console port. You may
find it convenient to use the serial console utility during the production stage to configure a large
number of NE-4000T modules before installing the modules in the serial device.
DI/O Settings
NE-4000T Embedded Network Enabler supports 8 Digital I/Os.
Digital Output
Each Digital Output uses 2 signals to control the devices connected to the terminal block on the
evaluation board (NE-4000T-ST), such as relay devices. The 2 signals are formed by changes
between high and low voltages. For example, you can program DOØ to maintain a “high voltage”
(in this case, the DOØ’s LED will not light up), and change to “low voltage” (in this case, the
DOØ’s LED will light up) when you wish to trigger the relay device. By using these 2 output
signals, you can control the on/off status of your devices.
3-3

NE-4000T Series User’s Manual Getting Started
Digital Input
Each Digital Input also uses the 2 signals mentioned above to recognize the messages coming
from your device, such as a sensor. Unlike Digital Output mode, NE-4000T waits passively for
incoming signals when set to Digital Input mode. For example, you can configure DIØ to be in the
“On” state, meaning no signal is coming in, when in the “low voltage” state. With this type of
setup, the state will change to “high voltage” when a signal is coming in. Use the Network Enabler
Administrator, discussed in Chapter 4, to configure the DI/O and on/off status.
Digital Output LED Circuit Design
The figure shown below represents the digital output LED circuit. This type of design is called a
“Sink.”
When you develop your own applications, you will need to follow the voltage limits shown below.
Min. Max. Unit
Low-level Input Voltage Maximum voltage when DI is set
to “Low” status. ----- 0.3xVCC V
High-level Input Voltage Minimum voltage when DI is set
to “High” status. 0.7xVCC ----- V
Low-level Input Voltage Maximum voltage when DO is set
to “Low” status. ----- 0.4 V
High-level Input Voltage Minimum voltage when DO is set
to “High” status 2.4 ----- V
The Digital Output carries a current of only 1 mA.
Operating Modes
Each of the four NE-4000T models supports a different operation mode. NE-4000T-RC supports
Real COM Mode, NE-4000T-TS supports TCP Server Mode, NE-4000T-TC supports TCP Client
Mode, and NE-4000T-UD supports UDP Mode. The four operation modes are described
separately in the following subsections. Note that the main difference between the TCP and UDP
protocols is that TCP guarantees delivery of data by requiring the recipient to send an
acknowledgement to the sender. UDP does not require this type of verification, making it possible
to offer speedier delivery. UDP also allows multicasting of data to groups of IP addresses.
Please note that the module’s operating mode cannot be changed by updating the firmware. Please
verify the desired operating mode for your NE-4000T when ordering.
3-4

NE-4000T Series User’s Manual Getting Started
Real COM Mode (NE-4000T-RC)
NE-4000T-RC comes equipped with COM
drivers that work with Windows
95/98/ME/NT/2000/XP systems. The driver
establishes a transparent connection between
host and serial device by mapping the IP:Port
of the NE-4000T-RC’s serial port to a local
COM port on the host computer.
The important point about Real COM Mode is that it allows users to continue using RS-232 serial
communications software that was written for pure serial communications applications. The driver
intercepts data sent to the host’s COM port, packs it into a TCP/IP packet, and then redirects it
through the host’s Ethernet card. At the other end of the connection, the NE-4000T-RC accepts the
Ethernet frame, unpacks the TCP/IP packet, and then transparently sends it to the appropriate
serial device.
TCP Server Mode (NE-4000T-TS)
NE-4000T-TS uses TCP Server mode to establish the Serial-to-Ethernet connection.
NE-4000T-TS provides a unique IP:Port address on a TCP/IP network. NE-4000T-TS waits
passively to be contacted by the host computer, allowing the host to establish a connection with
the serial device. Data transmission proceeds as illustrated below.
1. The host requests a connection from the
NE-4000T-TS configured for TCP Server
Mode.
2. Once the connection is established, data
can be transmitted in both directions—
from the host to the NE-4000T-TS, and
from the NE-4000T-TS to the host.
3-5

NE-4000T Series User’s Manual Getting Started
TCP Client Mode (NE-4000T-TC)
In TCP Client mode, NE-4000T-TC can actively
establish a TCP connection to a pre-defined host
computer when serial data arrives.
After the data has been transferred, NE-4000T-TC
can disconnect automatically from the host
computer by using the TCP alive check time or
Inactivity time settings. Refer to Chapter 4 for
more details
As illustrated in the figure, data transmission
proceeds as follows:
1. The NE-4000T-TC requests a connection to
the host.
2. Once the connection is established, data can
be transmitted in both directions—from the
host to the NE-4000T-TC, and from the
NE-4000T-TC to the host.
UDP Mode (NE-4000T-UD)
Compared to TCP communication, UDP is faster
and more efficient. In UDP mode, you can
unicast or multicast data from the serial device to
one or more host computers. The serial device
can also receive data from multiple host
computers, making this mode ideal for message
display applications.
