2. Getting Started
This chapter includes information about how to install MiiNePort E1 Series modules for development and
testing.
Wiring Precautions
This section describes some important safety precautions that you should pay attention to before
proceeding with any installation.
ATTENTION
Be sure to disconnect the power cord before installing or wiring the evaluation board.
ATTENTION
Determine 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.
ATTENTION
Take care when handling the evaluation boards. When plugged in, the evaluation boards’ internal
components generate heat, and consequently the board may feel hot to the touch.
You should also pay attention to the following:
•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. Separate paths
should be used to route wiring for power and devices. 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 wires
sharing similar electrical characteristics may be bundled together.
•Keep input wiring and output wiring separate.
•If power wiring and device wiring paths must cross paths, make sure the wires are perpendicular at the
intersection point.
•All wiring should be clearly labeled.
Installing the MiiNePort E1 onto the MiiNePort
E1-ST
Before using the MiiNePort E1-ST evaluation board with the module, be sure to disconnect the power
supply, network, and serial device. In the top center of the evaluation board, there is a MiiNePort E1 profile
that indicates where you should install the module on the evaluation board (shown in the below figure).
When attaching the module to the evaluation board, make sure the 8 pins on the module are securely
plugged into the 8 pin headers on the evaluation board.

MiiNePort E1 Series User Manual
14
After the module is installed, connect the power supply, network, and serial device to the evaluation board.
Selecting the Serial Interface
RS-232
To use an RS-232 serial interface, place the 6-pin jumper on JP19.
RS-485
To use an RS-485 serial interface, place the 2-pin jumper on the middle two pins of JP15 or the right-most
two pins of JP16 (labeled as 485EN), and place the 6-pin jumper on JP20.

MiiNePort E1 Series User Manual

Circuit Pad for External Connection
A circuit pad is provided on the right side of each evaluation board for the development of additional
application circuits.
Connecting the Power
Connect the 12-48 VDC power line with the evaluation board’s power jack. If the power is properly supplied,
the power LED (D15, as shown in the following figure) on the evaluation board will show a solid red color
until the system is ready, at which time the ready LED on the module will show a solid green color.
Connecting to the Network
To connect to the network for testing and development purposes, install the module on the evaluation board
and then plug the Ethernet cable into the RJ45 jack on the module. If the cable is properly connected, the
LED on the module will indicate a valid connection to the Ethernet as follows:

When using a private IP address for the module, which is the factory default, make sure the netmask and IP
settings are configured properly to access the module from a host on the network.

MiiNePort E1 Series User Manual
16
Connecting to a Serial Device
To connect to a serial device for testing and development purposes, the module should be installed on the
evaluation board. Make sure the serial interface is configured correctly before connecting the evaluation
board to the serial device. (Refer to Selecting the Serial Interface section above when you are using
jumper blocks to select the serial interface on the evaluation board.) The module’s serial signals are routed
to and from the RS-232 or RS-485 COM port on the evaluation board. Use a serial data cable to connect the
serial device to the COM port on the evaluation board.
Digital I/O Channel Settings
Each module has 3 digital I/O (DIO) channels. (Refer to the Pin Assignments section above for the
module’s configurable DIO pin description. Refer to MiiNePort E1-ST Evaluation Board Panel Layout to
select the corresponding setting on the evaluation board.) Software can configure all 3 DIO channels. A DI
channel is a channel that is operating in digital input mode; a DO channel is a channel that is operating in
digital output mode. You may use the evaluation board’s Digital Output LEDs and Digital Input DIP switches
as the digital input and output devices, or you may connect digital input/output devices to the DI/O
Terminal Block.
ATTENTION
When using a digital input device connected to the DI/O Terminal Block, the corresponding Digital Input
DIP switch must be set to OFF or High. Setting the DIP switch to ON or Low will interfere with the signal
from your digital input device.
For channels in digital output mode, Low and High status is controlled from within the web console. When
using a Digital Output LED as your output device, Low status is indicated by the LED lighting up, and High
status is indicated by the LED turning off.

3. Choosing the Proper Operation Mode
In this chapter, we describe the operation modes supported by MiiNePort E1 modules. Modes are available
for COM port mapping from the host computer, as well as operation modes for TCP/IP protocols. After
choosing the an operation mode in this chapter, refer to subsequent chapters for configuration details.
Overview
MiiNePort E1 modules act as a bridge to connect your serial devices to the Ethernet. The built-in TCP/IP
stack frees you from the tedious task of programming networking protocols. With one step you can choose
the proper operation mode, and then use your computer to access, manage, and configure your serial
devices from anywhere in the world over the Internet.
Traditional SCADA and data collection systems rely on serial ports (RS-232/422/485) to collect data from a
variety of instruments. Since MiiNePort E1 modules convert between serial and Ethernet signals, your
SCADA and data collection system can be made accessible from any device connected to a standard TCP/IP
network, regardless of whether the devices are used locally or at a remote site.
The MiiNePort E1 supports Real COM mode and four different socket modes—TCP Server, TCP Client, TCP
Mixed, and UDP Server/Client. The major 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
offers speedier delivery by not requiring this type of verification. In addition, UDP also allows multicasting of
data to groups of IP addresses.
Real COM Mode
Real COM mode allows users to continue using software that was written for pure serial communications
applications. Each module comes equipped with COM drivers for Windows systems (95 and above). The
driver maps the module’s serial port to an IP address and port number. 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 module accepts the Ethernet frame, unpacks the TCP/IP packet, and
then transparently sends the data to the attached serial device. The driver thus establishes a transparent
connection between the host and serial device, allowing the host to treat the networked device as if it was
directly attached.

MiiNePort E1 Series User Manual
18
ATTENTION
The Real COM driver comes with NPort Windows Driver Manager, which can be downloaded from the
product resource page at http://www.moxa.com.
ATTENTION
Real COM mode allows several hosts to simultaneously access the module. The driver controls host access
to attached serial devices by checking the host’s IP address against the Accessible IP list. Use the
Accessible IP table to restrict access to the module when a public IP address is required for your
application.
TCP Modes
TCP Server Mode
In TCP Server mode, the module is assigned a unique IP address and port number on the TCP/IP network.
The module waits passively to be contacted by the host computer, allowing the host computer to establish a
connection with and obtain data from the serial device. This operation mode also supports up to 4
simultaneous connections, so that multiple hosts can collect data from the same serial device—at the same
time. As illustrated in the figure, data transmission proceeds as follows:
1. The host connects to the module configured for TCP Server mode.
2. Once the connection is established, data can be transmitted in both directions—from the host to the
module, and from the module to the host.

MiiNePort E1 Series User Manual
19
TCP Client Mode
In TCP Client mode, the module can actively establish a TCP connection to a pre-defined host computer
when serial data arrives. After the data has been transferred, the module can be automatically disconnected
from the host computer by using the “TCP alive check time” or “Inactivity time” settings. Refer to the
following chapters for more details.
As illustrated in the figure, data transmission proceeds as follows:
1. The module actively establishes a connection based on the conditions set in the firmware. You may let
the module connect to a remote host on startup, or connect later when data from the serial device
arrives.
2. Once the connection is established, data can be transmitted in both directions—from the host to the
module, and from the module to the host.

MiiNePort E1 Series User Manual
20
TCP Mixed Mode
In TCP Mixed mode, the module has both TCP Server and Client settings. The MiiNePort module can act as a
TCP Server or Client depending on the application. This mode is suitable for applications where the serial
device actively sends data to the remote host and for applications where the remote host sends commands
or other data to the serial device at the same time. As illustrated in the figure below, data transmission
proceeds as follows:
1. Both the remote host and MiiNePort E1 can request a connection; if one acts as the TCP Client, the
other acts as the TCP Server.
2. After the connection is established, data transmission will proceed.
RFC2217 Mode
RFC2217 is an industrial public protocol for sharing serial devices over TCP/IP Ethernet networks. RFC2217
is similar to Moxa’s proprietary Real COM mode because it allows users to continue using software that was
written for pure serial communications applications. Each module comes equipped with COM drivers for
Windows systems (95 and above). The driver maps the module’s serial port to an IP address and port
number. 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.
NOTE
To select RFC 2217 mode, first select TCP Server mode and then set Communication protocol to RFC 2217.
For more details, refer to Chapter 7: Web Console Configuration.
