wiring could overheat, causing serious damage to your equipment.
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.

Selecting the Serial Interface
The MiiNePort module uses a standard TTL serial signal input. However, to make the evaluation more
convenient, the evaluation board has built-in RS-232 and RS-485 interfaces. Use a 6-pin jumper to select which
serial interface is active.
• RS-232: short the 6-pin jumper to JP13
• RS-485: short the 6-pin jumper to JP14

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 on the evaluation board (D14) will show a solid green color until the system is ready. When the
system is ready, 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, plug the Ethernet cable into the RJ45 jack on
the evaluation board. If the cable is properly connected, the LED will indicate a valid connection to the Ethernet
as follows:

When using a private IP address (192.168.xxx.xxx), be sure the netmask and IP address are configured to
allow hosts on the private network to access the module. Note that by default, the module is configured to use
a private IP address.
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. Be sure to select the serial interface you would like to use before you connect the evaluation
board to the serial device. (Refer to the 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.

your digital input device.
Digital I/O Channel Settings
Each module has four digital I/O (DIO) channels. (Refer to the Pin Assignment section in Chapter 1 for the
module’s configurable DIO pin descriptions. Refer to the Evaluation Board Layout section in Chapter 1 to
select corresponding settings on the evaluation board.) All four DIO channels can be configured by software. A
DI channel is a channel that operates in digital input mode; a DO channel is a channel that operates in digital
output mode. You can use the evaluation board’s Digital Output LEDs and Digital Input DIP switches as the
digital input and output devices, or you can connect digital input/output devices to the DIO Terminal Block.
For channels in digital output mode, the Low versus High setting is controlled from the web console. When
using a Digital Output LED as your output device, the LED will be on to indicate that the status is Low and the
LED will be off to indicate that the status is High.

3. Choosing the Proper Operation Mode
The MiiNePort modules support operation modes for COM mapping and TCP/IP. After choosing the proper
operation mode for your application, refer to subsequent chapters for configuration details.
The following topics are covered in this chapter:
Overview
Real COM Mode
TCP Server Mode
TCP Client Mode
RFC2217 Mode
UDP Mode
Ethernet Modem Mode
MCSC Mode (MiiNePort E2 Only)
MiiNePort E2/E3 Choosing the Proper Operation Mode
3-2
Overview
The MiiNePort acts as a bridge for connecting serial devices to Ethernet networks. After choosing the best
operation mode for your application, you can 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
various kinds of instruments. Since MiiNePort modules convert between serial and Ethernet signals, you will be
able to access your SCADA and data collection system from hosts connected to a standard TCP/IP network,
regardless of whether the devices are used locally or at a remote site.
The MiiNePort modules support Real COM mode and six different socket modes—TCP Server, TCP Client,
Ethernet Modem, RFC2217, UDP, and MCSC. 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 kind of verification, and consequently UDP is faster than TCP. 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
module’s serial port is mapped by the driver 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. In other words, a PC host can treat networked
devices as though the devices were connected directly to the PC.
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. TCP Server mode supports up to four simultaneous
connections so that multiple hosts can collect data from the same serial device—at the same time. Data
transmission proceeds as follows:
MiiNePort E2/E3 Choosing the Proper Operation Mode
3-3
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.
TCP Client Mode
In TCP Client mode, the module can actively establish a TCP connection to a predefined 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 subsequent chapters
for details. 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.

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 in that 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 module’s serial port is mapped by the driver 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.
UDP Mode
UDP is similar to TCP but is faster and more efficient. Although data can be broadcast to or received from
multiple network hosts, UDP does not support data verification, and consequently is not suitable for
applications for which data integrity is critical. UDP would, however, be suitable for message display
applications.

ATTENTION
The Real COM driver comes with NPort Windows Driver Manage
ROM shipped
with the MiiNePort Starter kit.
ATTENTION
Real COM mode allows several hosts to simultaneously access to the MiiNePort 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.

Ethernet Modem Mode
Ethernet Modem Mode is designed for use with legacy operating systems, such as MS-DOS, that do not support
TCP/IP Ethernet. By connecting the MiiNePort evaluation board’s serial ports to an MS-DOS computer’s serial
port, it is possible to use legacy software originally designed to transmit data via modem, but now transmit the
data over the Ethernet.
MCSC Mode (MiiNePort E2 Only)
MCSC (Multiple Channel Serial Communication) was developed for multiple serial-to-Ethernet applications that
use only one serial port. For example, if you need your device to act as a TCP Server and TCP Client at the same
time (as illustrated below), you can use MCSC.
For details on MCSC’s functionality and configuration, refer to Chapter 8: NetEZ Technologies’ MCSC. MCSC
is only supported on the MiiNePort E2.

4. Choosing the Configuration Tool
The MiiNePort supports several tools for configuring the module. In this chapter, we briefly describe the options
available and appropriate situations for using those options.
The following topics are covered in this chapter:
Utility Console
Web Console
Telnet Console
SCM (Serial Command Mode)

Utility Console
Device Search Utility
You can find the Device Search Utility on the CD-ROM that came with your product. NPort Search Utility is
designed for Windows and is mainly used to search for the MiiNePort modules and for assigning IP addresses.
Refer to the Web Console for additional configuration information.
NPort Windows Driver Manager
NPort Windows Driver Manager is intended for use with Real COM mode. The software manages the installation
of drivers that allow you to map unused COM ports on your PC to serial ports on the MiiNePort.
Refer to Chapter 6: Utility Console and Driver Installation for details on how to use the Device Search
Utility and NPort Windows Driver Manager.
Web Console
After locating a MiiNePort with the Device Search Utility, you may configure the MiiNePort using a standard web
browser. Refer to Chapter 7: Web Console Configuration for details on how to access and use the MiiNePort
web console.

Telnet Console
Your MiiNePort can be configured over the network with Telnet, which requires that the module has a network
connection and an IP address. We briefly discuss Telnet console configuration in Chapter 5: Initial IP
Address Configuration. All Telnet console commands are introduced in Chapter 7: Web Console
Configuration.
SCM (Serial Command Mode)
The MiiNePort’s SCM (Serial Command Mode) allows the module’s parameters to be retrieved and configured
through the serial port. This is accomplished using specially parsed commands sent to the module through the
serial port.
SCM is often used when your device has already been used in a real application and a configuration change,
such as changing the device’s IP address with the device’s key pad, is required.
Refer to Chapter 7: Web Console Configuration for details on how to access and use the MiiNePort’s SCM.
Refer to Appendix A: Introduction to SCM (Serial Command Mode) for the SCM command set
instructions.

5. Initial IP Address Configuration
When setting up your MiiNePort module for the first time, the first thing you should do is configure the IP
address. This chapter introduces the methods that can be used to configure the module’s IP address. For more
details about network settings, refer to the Network Settings section in Chapter 7: Web Console
Configuration.
The following topics are covered in this chapter:
Static vs. Dynamic IP Address
Factory Default IP Address
ARP

ATTENTION
Consult your network administrator on how to reserve a fixed IP address for the module in the MAC
mapping table when using a DHCP Server or BOOTP Server. For most applications, you should assign a fixed
IP address to the module.
ATTENTION
In order to use ARP, both your computer and the module must be connected to the same LAN. You may also
use a crossover Ethernet cable to connect the module directly to your computer’s Ethernet port. Your module
must be configured with the factory default IP
Static vs. Dynamic IP Address
You should first determine whether the module will be assigned a Static IP or Dynamic IP (either DHCP or
BOOTP application).
• If the module is used in a Static IP environment, you need to configure the IP address directly.
• If the module is used in a Dynamic IP environment, you need to configure the module to obtain an IP
address dynamically with DHCP, DHCP/BOOTP, BOOTP, or AUTOIP.
Factory Default IP Address
The MiiNePort module is configured with the following default private IP address:
192.168.127.254
IP addresses of the form 192.168.xxx.xxx are referred to as private IP addresses, since it is not possible to
directly access a device configured with a private IP address from a public network. For example, you would not
be able to ping such a device from an outside Internet connection. Applications that require sending data over
a public network, such as the Internet, require setting up the server with a valid public IP address, which can
be leased from a local ISP.
ARP
You can use the ARP (Address Resolution Protocol) command to set up the module’s IP address. The ARP
command tells your computer to associate the module’s MAC address with the intended IP address. You must
then use Telnet to access the module, at which point the module’s IP address will be reconfigured.
-IP
address before executing the ARP command.
To configure the IP address using ARP, follow these instructions:
1. Obtain a valid IP address for the module from your network administrator.
2. Obtain the module’s MAC address from the label on the module.
3. Execute the arp -s command from your computer’s MS-DOS prompt by typing:
arp –s <new IP address> 00-90-E8-tt-tt-tt
For example,
arp –s 192.168.200.100 00-90-E8-00-00-00
In this example, 192.168.200.100 is the new IP address and 00-90-E8-00-00-00 is the module’s MAC
address, as obtained in steps 1 and 2.
4. Execute a special Telnet command by typing:
telnet <new IP address> 6000
For example,
telnet 192.168.200.100 6000
