equipment.
Temperature Caution!
Be careful when handling CN2510. When plugged in, CN2510’s internal components generate heat, and
consequently the board may feel hot to the touch.
Hardware Installation
Desktop
Place your CN2510 on a clean, flat, well-ventilated desktop. For better ventilation, attach the 4 pads from the
desktop kit to the bottom of the unit, and leave some space between the CN2510 and other equipment. Do not
place equipment or objects on top of the unit, as this might damage the server.
Rackmount
CN2510 is designed to be mounted on a standard 19-inch rack. Use the enclosed pair of L-shaped metal
brackets and screws to fasten your CN2510 to the rack cabinet. Each L-shaped bracket has 6 holes, leaving two
outer or inner holes available for other uses. You have two options. You can lock either the front or rear panel
of the CN2510 to the front of the rack. Locking the front panel is shown in the following figure.

ATTENTION
CN2510
You should also observe the following common wiring rules:
• 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.
• 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 separate.
• Where necessary, it is strongly advised that you label wiring to all devices in the system.
Connecting CN2510-8/16’s Power
Connect CN2510’s 100-240 VAC power line to its AC connector. If the power is properly supplied, the “Ready”
LED will show a solid red color until the system is ready, at which time the color changes to green.
Connecting CN2510-8/16-48V’s Power
To connect CN2510-8/16-48V’s power cord to its terminal block, follow the steps given below:
Loosen the screws on the V+ and V- terminals of CN2510-8/16-48V’s terminal block.
Connect the power cord’s 48 VDC or -48 VDC wire to the terminal block’s V+
the power cord’s DC Power Ground wire to the terminal block’s V- terminal, and then
tighten the terminal block screws.
(Note: CN2510-8/16-48V will still operate properly if the 48V/-
wires are reversed.)
If the power is properly supplied, the “Ready” LED will show a solid red color until the system is ready, at which
time the color changes to green.

Grounding CN2510-8/16-48V
Run the ground connection from the ground screw to the grounding surface prior to
devices to CN2510.
The Shielded Ground (sometimes called Protected Ground) contact is the second contact from the right of the
5-pin power terminal block connector located on the rear panel of CN2510-8/16-48V. Connect the SG wire to
the Earth ground.
-8/16-48V should be mounted to a well-grounded surface, such as a metal panel.

connected to a 10 Mbps Ethernet network.
NOTE
If your network is already set up, telnet over the network to CN2510’s IP address to access the Console Utility.
If your network environment is not set up, use Moxa PComm Terminal to establish a direct serial console
connection.
Connecting to the Network
Connect one end of the Ethernet cable to CN2510’s 10/100M Ethernet port and the other end of the cable to the
Ethernet network. There are 2 LED indicators located on the top left and right corners of the Ethernet connector.
If the cable is properly connected, CN2510 will indicate a valid connection to the Ethernet in the following ways:
corner LED indicator maintains a solid green color when the cable is properly
top left corner LED indicator maintains a solid orange color when the cable is properly
Connecting to a Serial Device
Use appropriately wired serial data cables to connect serial devices to CN2510’s serial ports.
Connecting to the Console Port
A console is a combination of keyboard and monitor that is used to configure settings and monitor the status
of your system. The console port can be used if a network is unavailable, or you do not know CN2510’s IP
address. To connect to the console port, use a PC running UNIX, or a PC with terminal emulation software (e.g.,
HyperTerminal or PComm by Moxa; parameter settings are: baud rate = 115200 bps, parity check = None,
data bits = 8, stop bits = 1, terminal type = VT100). Use an RJ45-to-DB25 or RJ45-to-DB9 cable to connect the
terminal to the console port.
Accessing the Console Utility
The Console Utility is the main application used to set up the server, configure the ports, and run utilities (ping,
diagnosis, monitor, and upgrade). There are two ways to access the Console Utility—with terminal emulation
from a console terminal, or with Telnet from a network terminal.
Configuration Checklist
You will need the following information to configure CN2510. Check with your network administrator if you do
not know all of the required information.
Basic CN2510 Information:

Accessing the Console from a Telnet Terminal
Connect CN2510 to your LAN and then turn on the power. Use the Moxa Windows Utility to find CN2510’s IP
address, and then telnet to the IP address to enter the CN2510 console.
CN2510 Windows Utility
The CN2510 Utility is a convenient Windows utility that can be used to find both the name and IP address of
your CN2510. Once you know the IP address, you can telnet CN2510 over the network to complete the
configuration process and to gather information about all servers on the network.
1. Run upgrade.exe, located in the \Software\Firmware\ folder on the CN2510 Documentation and Software
CD, or run NPort Tool Firmware Utility from the Start menu.
2. The CN2510 Utility will search for all CN2510s on the network.
3. The CN2510 Utility lists all available servers on the network. Note that servers in grey are password
protected. Double click the server’s name, or click on from the menu bar to see the server settings.

Async server name—CN2510 uses this name to identify itself when requested by an SNMP station or UNIX
host. Use an ASCII string with maximum length of 40 characters for the name. Spaces are allowed.
Async server location—CN2510 reports this location to the SNMP station when requested. Use an ASCII
string with maximum length of 44 characters for the location. Spaces are allowed.
Async server serial number—Each CN2510 Async Server is assigned a unique serial number before it
leaves the factory. The serial number cannot be changed.
Domain server 1/2 IP address—A Domain Name Server is a network host that translates host names to
IP addresses. Hosts use the Domain Name Server to request the IP address that corresponds to a particular
url (such as www.moxa.com
server 1 IP address field, and the IP address of the secondary Domain Name Server in the Domain
server 2 IP address field. When CN2510 receives a connection request, CN2510 first checks the host
table defined on the Host_table page. If a matching entry cannot be found, CN2510 sends a query to the
Domain Name Server.
WINS function disable—Enable or disable the WINS server. The default setting is “enable.”
WINS server IP address—If a WINS Server is connected to the network, use this field to record the WINS
Server’s IP address. TCP/IP uses IP addresses to identify hosts, but users often use symbolic names, such
as computer names. The WINS (Windows Internet Naming Service) Server, which uses NetBIOS over
TCP/IP, contains a dynamic database to map computer names to IP addresses.
). Input the IP address of the primary Domain Name Server in the Domain
Console password—If you specify a password, write it down for safe keeping. If you forget the password,
you will need to use the reset password button to reset it. Only use the console password when absolutely

Ethernet speed [ ---- ]
Ethernet address [00:90:E8:26:10:09]
DHCP (client)—When DHCP is enabled, CN2510 will request an available IP address and Netmask over the
network from the DHCP Server. If an IP address is not available, CN2510 will use the current IP address, but
will continue sending requests to the DHCP Server.
Async server IP address—This field MUST contain an IP address unique to the network. The IP address
is written using the notation “ddd.ddd.ddd.ddd,” in which each “ddd” is a nonnegative decimal number
strictly less than 256 (i.e., an 8-bit integer). The default value is 192.168.127.254.
Async server IP netmask—A netmask is used to group network hosts into subnets. CN2510 sends TCP/IP
packets directly to hosts that are on the same subnet. If the recipient of the packet is NOT on the same
subnet, the packet is sent to the default gateway IP address.
Default gateway IP address—This field contains the IP address of a router on the local network. The
default gateway is used when a packet is sent to an IP address that is not on the subnet specified in
CN2510’s local routing table.
Ethernet speed—If the Ethernet port is active, the Ethernet speed will be set automatically to 10BaseT or
100BaseT. This field cannot be modified.
Ethernet address—This field contains the hardware Ethernet address. This field cannot be modified.

RADIUS server IP—The IP address of the RADIUS (Remote Authentication Dial-In User Service) server is
used to authenticate remote dial-in users connecting from an ISP (Internet Service Provider). Leave this
field blank if you do not have a RADIUS server on your network.
Windows NT includes RADIUS software. For UNIX-based platforms, refer to Appendix B for information
about setting up a RADIUS server.
NOTE: The RADIUS server and CN2510 SHOULD be able to communicate with each other. To verify this,
check to see if you can ping from each server to the other.
RADIUS server IP—This is the IP address of the RADIUS server.
RADIUS key—This is a shared key used by the RADIUS protocol. If you have a RADIUS server, you will
need to enter the password in this field.
UDP port (1:1645 2:1812)—RADIUS originally used port 1645, but more recently this conflicted with the
RFC standard, so the officially assigned RADIUS port is now 1812. Check which UDP port your RADIUS
server software uses to determine the proper choice.
Enable RADIUS accounting—The default for this field is no. If your RADIUS Server offers this function,
set it to yes.
SNMP community name—The SNMP community name can be used to guarantee minimal security for
SNMP communication. Only SNMP stations with the same community name can access SNMP agents (such
as Async Server). Choose a community name with no more than 16 ASCII characters. The default name is
“public.”
SNMP trap server IP address—This field specifies the IP address of the SNMP trap server. CN2510 will
report to the SNMP trap server each time it restarts. You may leave this field blank if SNMP is not needed.
Ethernet IP forwarding—CN2510 can forward packets between different segments of a TCP/IP network.
When enabled, CN2510 will use its Ethernet routing ability to identify which incoming packets should be
forwarded.
Routing protocol—CN2510 supports RIP (Routing Information Protocol) versions 1 and 2, a widely used
protocol specifying how routers exchange routing table information. When RIP is activated, routers (or
CN2510s) periodically exchange entire routing tables.
TCP retransmission timeout—This is the amount of time CN2510 waits to retransmit after a transmission
failure occurs.

3. Knowing Your Application
This chapter discusses a variety of applications for CN2510 Async Server. Refer to the diagrams in each section
to see which application most closely matches your own. Determining which application you should choose will
save time configuring both the hardware and software.
CN2510 is an Async Server that can support simultaneously different operation modes for different serial ports.
The examples in this chapter explain each operation mode in detail. You can create a wide variety of
applications by using different combinations of operation modes on the same Async Server.
NOTE: Each section title consists of an application name that uses terminology common to our industry,
followed in parentheses by the application name used in CN2510’s console utility. For example, the CN2510
application that corresponds to Linux Real TTY/Unix Fixed TTY is NT Real COM mode.
The following topics are covered in this chapter:
Windows Real COM (NT Real COM)
Linux Real TTY/Unix Fixed TTY (NT Real COM)
Device Control (Device Control)
UDP Communication (Raw UDP)
Console Management (Reverse Terminal)
Terminal Access (Terminal)
Multi-host TTY (Multi-host TTY)
Dial-in/Out-of-Band Management (Dialin/out)
Network Printer (Printer)
Multiplexor Access (Multiplex)

Windows Real COM (NT Real COM)
Moxa provides CN2510 COM port drivers for all Windows operating systems. The COM port driver serves a dual
purpose—(1) convert serial data into Ethernet packets, (2) convert Ethernet packets into serial data—as
outlined in the following table:
PC CN2510 Serial Device Serial Device CN2510 PC
1. The PC generates RS-232 serial COM commands.
2. The COM port driver converts the commands
into Ethernet packets.
3. The packets are sent over the network to CN2510’
Ethernet port.
4. CN2510 converts the Ethernet packets back into
RS-232 serial format.
5. The commands are delivered to serial device(s)
connected to CN2510’s serial port(s).
You can enhance your applications greatly by using CN2510 to access serial devices over an Ethernet network,
and since CN2510 and the COM driver handle all protocol conversion tasks, you won’t need to modify the
software currently in use. In fact, multiple PCs can access the serial ports of one CN2510, as shown in the
figure.
Refer to Chapter 4 for detailed information and configuration instructions.
1. A serial device connected to CN2510 starts
transmitting serial data.
2. CN2510 converts the data into one or more
Ethernet packets.
3. The packets are sent over the network to the PC
host’s Ethernet port.
4. The COM port driver converts the Ethernet
packets back into RS-232 serial format.
5. The serial data is processed by the program that
controls the serial device.
CN2510 Knowing Your Application
3-3
Linux Real TTY/Unix Fixed TTY (NT Real COM)
Real TTY drivers that control Moxa CN2510 Async Server’s serial ports are provided for Linux environments.
This means that CN2510 Async Server can be used with existing Linux-based applications that use multiport
serial boards, since the host PC will recognize CN2510’s COM ports as real TTY ports. You can enhance your
applications by using CN2510 to access serial devices over an Ethernet network, but without needing to modify
the software currently in use.
Moxa also provides Fixed TTY port drivers for Unix environments. However, the Linux Real TTY and Windows
Real COM port drivers provide better control over serial port data transmission, since you can control modem
signals such as DTR, DSR, RTS, and CTS. The Unix Fixed TTY driver provides software reception and
transmission through CN2510’s serial ports, but does not allow you to control the DTR, DSR, RTS, and CTS
modem signals.
Refer to Chapter 4 for detailed information and configuration instructions.
CN2510 Knowing Your Application
3-4
Device Control (Device Control)
The CN2510 Device Control application allows you to choose between two different operation modes: ASPP and
RAW.
ASPP Mode—For applications that require setting up communication parameters or controlling modem signals
(DTR, RTS, Break, etc.), take advantage of Moxa’s ASPP lib to simplify your programming tasks. ASPP takes
care of the more basic protocol-level programming tasks, and allows you to concentrate your energy on higher
level, application-specific tasks.
RAW Mode—To control device data transmission directly, set CN2510 for TCP RAW mode. Device control
applications can use standard Linux/Unix Socket programming in Linux/Unix environments, or WinSock
programming in Windows environments. Standard socket programming allows you to focus on pure data
transmission, without needing to write code for controlling serial ports or modem signals. ASPP can also be
used to communicate with CN2510.
Linux/Unix socket programming and Windows WinSock programming both use IP as the communication agent
between hosts and devices. RAW mode is a good solution for handling pure serial data communications
applications that do not require setting up communication parameters (baud rate, parity, etc.).
Refer to Chapter 5 for detailed information and configuration instructions.
