The SN3101 can also work in tandem with other remote management products
– such as the Altusen PN9108 Power over the NET™ remote power
management system – to provide convenient, reliable, and effective, remote
data center device management.
Since the SN3101 is fully compatible with existing serial communications
software, your current investment in software development is protected.
Software designed to work with COM or TTY ports can access serial devices
over a TCP/IP network by utilizing the SN3101’s Real COM or TTY drivers.
This feature also breaks through the port number and distance limitation
barriers encountered with PC hardware.
Installation is fast and easy: plugging cables into their appropriate ports is all
that is entailed. An offering of browser based GUI, Telnet (SSH), VT console
terminal sessions, and a Windows software utility, make configuration and
operation smooth and convenient.
The SN3101's firmware is upgradeable over the Net, so you can stay current

Port Operating Modes
Overview
To cover a broad range of serial applications, the SN3101’s COM port supports
several port operating modes. These include Virtual Modem, Serial Tunnel,
Console Management, and Real COM Port modes, for device control sessions,
plus TCP Server/Client, UDP, and Modbus modes for socket application
purposes. An explanation of the functions performed by the various operating
modes is provided in the sections that follow.
Console Management
In Console Management mode, multiple users can establish a Telnet or SSH
session to the SN3101 to manage a server or serial device connected to its
COM port. Users can log in using the browser Telnet function, a direct Telnet
session, SSH or PuTTY.
Note: Be sure that the Socket entry specified on the Network page corresponds
to the port that the device listens on. 5001 is the SN3101’s default
setting (see Network, page 16, and Socket, page 17).
Real COM Port
This mode is used in conjunction with a virtual COM port driver installed on
the remote user's local computer. (See Chapter 8, Virtual Port Management for
virtual port management details.) When the SN3101’s COM port set to this
mode, the device connected to the port appears as if it were a device directly
connected to a COM port on the remote user's local computer.
This mode is useful with devices such POS terminals, Bar Code Readers, Serial
printers, etc. since it allows you to use software that was written for pure serial
communication applications. It can be used with other Altusen management
products, such as the PN9108 Power Over the NET™.
The SN3101 comes with Real COM drivers for Windows systems and TTY
drivers for Linux systems. See Chapter 8, Virtual Port Management for
installation and operation details.
Note: Real COM Port mode supports the Dir ect Access function (see Direct
Access, page 46, for details).
SN3101 User Manual
26
TCP Server / TCP Client
TCP (Transmission Control Protocol) provides a reliable transport layer for
transmitting serial data over the TCP protocol via socket programming.
TCP Server (RAW TCP)
In TCP Server (RAW TCP) mode, data transmission is bidirectional. In this
mode, the host computer initiates contact with the SN3101 and requests a
connection to its serial port.
Once the connection is established, the host receives data from the serial
device. From this point on, data can be transmitted between the host and the
device in both directions. 128-bit/256-bit SSL (TLS v1.0) data encryption is
supported in this operating mode.
The SN3101 supports simultaneous connections from up to 16 host computers
in this mode, allowing multiple computers to communicate with the serial
device at the same time.
Note: 1. Be sure that the Socket entry specified on the Network page
corresponds to the port that the device listens on. 5001 is the
SN3101’s default setting. (See Network, page 16, and Socket,
page 17.)
2. TCP Server mode supports the D irect Access function (see Direct
Access, page 46, for details).
TCP Client
In TCP Client mode, when serial data comes into the SN3101’s serial port, the
SN3101 initiates contact with the host computer and begins sending serial data
to the to the host. The SN3101 can send data to up to 16 host computers
simultaneously, and supports 128-bit/256-bit SSL (TLS v1.0) data encryption
in this operating mode.
Chapter 5. Port Operating Modes
27
UDP Mode
UDP (User Datagram Protocol) Mode is faster and more efficient at
communications than TCP. In UDP mode, communications are bilateral. A
serial device can send data to, and receive data from, up to 16 host computers
via the SN3101’s COM port.
Because it doesn’t perform error checking in the thorough way that TCP does,
UDP is more suitable for real time applications (such as message display) than
the slower TCP which is optimized for data accuracy.
Modbus
Modbus follows a Master/Slave model that allows communication between
many serial devices connected to the same network. It is often used to connect
a supervisory computer with a remote terminal unit (RTU) in supervisory
control and data acquisition (SCADA) systems.
In Modbus mode, the SN3101 acts as a gateway to link individual serial
Modbus devices. Acting as a Modbus master, the SN3101 initiates transactions
and the slaves respond with the requested data. Because it communicates using
TCP over the Internet, the SN3101 eliminates the distance limitations of
traditional Modbus serial communications.
Note: Modbus RTU and Modbus ASCII slave modes support the Direct
Access function (see Direct Access, page 46, for details).
SN3101 User Manual
28
Virtual Modem
In Virtual Modem mode, the SN3101’s COM port emulates a modem. The port
acts as if it were a real modem for communication with a remote server. This
allows software designed to transmit data over a serial modem-to-modem link,
to perform serial operations over a TCP/IP ethernet connection. In this mode,
the SN3101 “dials into” the remote server’s IP specifying the appropriate port
address for the transmission. For example:
atd 10.0.100.101:5000
A detailed description of the data structures and related functions of the
SN3101’s virtual modem function is provided on page 105.
Note: 128-bit/256-bit SSL (TLS v1.0) data encryption is supported in this
operating mode.
Serial Tunnel
Serial Tunnel involves establishing a direct connection between two SN3101’s
over Ethernet. Serial Tunnel works in a TCP Client/TCP Server relationship.
One unit is designated TCP Client, the other designated TCP Server.
Note: In this configuration, it doesn’t matter which one is designated TCP
Client and which one is designated TCP Server.
The COM port of one unit connects to the COM port of a computer; the COM
port of the other unit connects to the serial device that will be accessed.
The units communicate with each other via their IP and port addresses. The
port address is set with the Socket entry of the Network Configuration settings.
See Network, page 16, and Socket, page 17, for details.
Note: 1. Serial Tunnel cannot be configured with the browser interface. It must
be configured with the Serial Network Device Manager software.
(See Serial Network Device Manager, page 69.)
2. 128-bit/256-bit SSL (TLS v1.0) data encryption is supported in this
operating mode.

The configuration settings are described in the following table:
*These fields only need to be filled in for an SN3101 whose COM port has
been configured as a Modbus Master (an SN3101 that has a Modbus
master device connected to it).
Setting Explanation
Initial Delay Time This is the amount of time to wait after the SN3101 boots up
before Modbus starts. This gives attached devices (PLCs,
IEDs, etc.), time to initialize.
Remote Slave IP* These are the IP addresses of the SN3101s whose COM
ports have been configured as Modbus slaves (ones that
have Modbus slave devices connected to them).
TCP Port* The port that an SN3101 whose COM port has been
configured as a Modbus slave listens for data on. The
default port number is 502.
ID Range* The range of numbers for devices (PLCs, IEDs, etc.),
connected to the SN3101 whose COM port has been
configured as a Modbus slave. The SN3101 configured for
Modbus Master decides which SN3101 Modbus slave to
communicate with depending on the ID specified in the
packet sent by the host.
Auto Slave Unit ID
Enable: Modbus data from the master Modbus device is
sent out over the serial port without changing the Modbus
ID contained in the Modbus packet
Disable: Modbus data from the master Modbus device is
sent out over the serial port with the Modbus ID
contained in the Modbus packet changed to a user-
specified ID. Specify the desired ID (from 1 – 247), when
this parameter is selected.
Character Timeout This parameter is used when the SN3101 is configured for
Modbus RTU Mode. It is used for Modbus to identify the
start / end of a packet. Valid settings are from 0 – 3000ms.
A setting of zero indicates that the SN3101 should use the
standard Modbus timeout value.
Message Timeout This parameter is used when the SN3101 is configured for
Modbus RTU/ASCII Mode. If the Modbus device does not
receive a response within the time specified here, the
communication times out. Valid settings are from
10 – 3000ms.
Modbus/TCP
Exception
If set to Yes, error messages (TCP exception codes) are
generated if a problem (such as a message timeout) should
occur during Modbus operations.

Virtual Port Management
Overview
The SN3101 offers Virtual COM Port support – Real COM Port drivers for
Windows, as well as a TTY driver for Linux. By running the driver on a local
computer, devices connected to the SN3101’s COM port, appear as if they are
directly connected to a COM port on the local computer. Data transmission
takes place over the Internet between the local computer’s virtual COM port
and the device connected to the SN3101’s COM port.
Note: Only a port designated as a Real COM Port can be configured as a
virtual port. See Operating Mode, page 37, for details.

Real COM Port Management – Windows
The Virtual Port Management Utility for Windows provides a convenient
interface to COM port mapping. When you run the Virtual Serial Port
Manager program (Start
Virtual Port Management Utility
Virtual Serial
Port Manager), the following dialog box appears:
Dialog Box Layout
The Virtual Port Management Utility dialog box is laid out as follows:
The menu and button bars allow the automatic enumeration and listing of
devices and ports.
Below the menu and button bars, there is an area to input information in
order to manually list target devices if the device doesn’t appear using the
automatic enumeration method.
All target devices that were found by enumeration or manually entered are
listed in the left side panel.
All ports that were found for a selected target device are enumerated in the
central panel.
The right side panel displays the virtual COM port mappings that you have
made.
Chapter 8. Virtual Port Management
61
Menu and Toolbar
The Virtual Port Management Utility menu and toolbar have the same captions
and functions. Users can either click the menu items or buttons to invoke the
desired function, as shown in the table below:
Target Information
The Target Information fields allow a user to install (map) ports on an offline
target device, as follows:
Item Action
Enum Targets This function searches and lists all SN devices on the LAN –
these include SN0108 and SN0116 devices, as well as
SN3101s. The results are shown in the Target List panel (see
Target List, page 62, for details). Be aware that all devices
listed in the Target List will be deleted when the delete function
is invoked. Be sure to remove any devices from the list that
you don’t want to delete before invoking the delete function.
Enum Ports This function lists the existing ports for the target device
currently selected in the Target List. The results are shown in
the Port List panel.
Map After selecting a port from the Port List panel, selecting this
function maps the device’s COM port to a virtual COM port on
the user’s computer.
Unmap After selecting a port from the Mapped Ports list, selecting this
function removes the mapping between the computer and the
device’s COM port.
Field Action
Target IP Address Input the IP address of the target that you want to map COM
ports to.
Base Socket Port The base socket port of the target device. For Real COM port
operation, the default base socket port is 5200.
Target Name The name of the target. If it is different from the target’s real
name, it will be replaced by the real one. Note that the name is
not related to the mapping or unmapping process. Only the IP
address, socket port and target type are relevant.
Target Type The type of target to be mapped. SN3101, SN0108, and
SN0116 devices are valid target types.
Add Target Creates an entry in the Target List based on the above
information.
Delete Target Remove the currently selected target from the Target List.

Target List
The left side panel displays all the devices that were found with the
Enumeration function, as well as any devices that were manually added with
the Target Information fields.
Note: Double clicking an item in the list invokes the same function as
selecting Enum Ports – which displays the numbers and working
modes of the selected target’s ports in the Port List column.
If a device was automatically listed as a result of the Enumeration
procedure, the icon to its left is drawn with green dots and lines to show
that the target is on line and is ready to be mapped.
If a device was added to the list manually and is off line, the icon to its left
is drawn with black dots and lines. Double clicking a manually added item
can get some information and display it in the Port List, but the working
mode information is not accurate and we must assume that all the device’s
ports are in Virtual Port mode. See Operating Mo de, page 37 for details
about port modes.
If the target is off line or is on line but does not respond within 2 seconds
of asking to enumerate its ports, the working mode information is not
accurate and we must assume that all the device’s ports are in Virtual Port
mode. See Operating Mode, page 37 for details about port modes.
Chapter 8. Virtual Port Management
63
Port List
This list displays the port information of the selected target (only one target can
be selected at a time).
The left column lists the target’s port number, the second column shows
the COM port it is mapped to (if any), the third column shows its working
mode, and the right column shows its status.
Note: The working mode refers to the setting for the port that was
specified when the port was configured. See Port Confi guration,
page 35, for details.
Double clicking a port in the Port List brings up the Por t Ma ppi ng dialog
box. See Port Mapping, page 64 for mapping details.
Note: The Port Mapping dialog box can also be invoked either by clicking
MapTo… on the toolbar or selecting MapTo… from the menu.

LDAP Server Configuration
Introduction
The SN3101 allows log in authentication and authorization through external
programs. This chapter describes how to configure Active Directory and
OpenLDAP for SN3101 authentication and authorization.
Active Directory
To allow authentication and authorization for the SN3101 via LDAP or
LDAPS, the Active Directory’s LDAP Sch ema must be extended so that an
extended attribute name for the SN3101 – accessPort – is added as an optional
attribute to the person class.
Note: Authentication refers to determining the authenticity of the person
logging in; authorization refers to assigning permission to use the
device’s various functions.
In order to configure the LDAP server, you will have to complete the following
procedures: 1) Install the Windows Server Support Tools; 2) Install the Active
Directory Schema Snap-in; and 3) Extend and Update the Active Directory
Schema.

SN3101 User Manual
86
The Permission Attribute Value
The attribute value for accessPort is made up of two parts: 1) the IP address of
the SN3101 a user will access; and 2) a string that indicates the access rights
the user has on the SN3101 at that IP address. For example:
192.168.0.60&u,t,1;u,f
The makeup of the permission entry is as follows:
An ampersand (&) connects the SN3101’s IP with the access rights string.
The access rights string is made up of various combinations of the
following characters: u, t, f, a, and 1 (one). The characters can be entered
in upper or lower case. The meanings of the characters is provided in the
Permission String Characters table, below.
The characters in the access rights string are separated by a comma (,).
There are no spaces before or after the comma.
If a user has access rights to more than one SN3101, each permission
segment is separated by a semicolon (;). There are no spaces before or
after the semicolon.
Permission String Characters
Character Meaning
U (User) User has port access rights.
T (True) User has port configuration rights.
F (False) User does not have port configuration rights.
A (All) User has rights to all ports.
1 (One) User has rights to port 1.

OpenLDAP
OpenLDAP is an Open source LDAP server designed for Unix platforms. A
Windows version can be downloaded from:
http://download.bergmans.us/openldap/openldap-2.2.29/
openldap-2.2.29-db-4.3.29-openssl-0.9.8a-
win32_Setup.exe.
OpenLDAP Server Installation
After downloading the program, launch the installer, select your language,
accept the license and choose the target installation directory. The default
directory is: c:\Program Files\OpenLDAP.
When the Select Componen ts dialog box appears, select instal l B DB-t ools and
install OpenLDAP-slapd as NT service, as shown in the diagram, below:
Chapter 10. LDAP Server Configuration
89
OpenLDAP Server Configuration
The main OpenLDAP configuration file, slapd.conf, has to be customized
before launching the server. The modifications to the configuration file will do
the following:
Specify the Unicode data directory. The default is ./ucdata.
Choose the required LDAP schemas. The core schema is mandatory.
Configure the path for the OpenLDAP pid and args start up files. The first
contains the server pid, the second includes command line arguments.
Choose the database type. The default is bdb (Berkeley DB).
Specify the server suffix. All entries in the directory will have this suffix,
which represents the root of the directory tree. For example, with suffix
dc=aten,dc=com, the fully qualified name of all entries in the database
will end with dc=aten,dc=com.
Define the name of the administrator entry for the server (rootdn), along
with its password (rootpw). This is the server's super user. The rootdn
name must match the suffix defined above. (Since all entry names must
end with the defined suffix, and the rootdn is an entry.)
An example configuration file is provided in the figure, below:
SN3101 User Manual
90
Starting the OpenLDAP Server
To start the OpenLDAP Server, run slapd (the OpenLDAP Server executable
file) from the command line. slapd supports a number of command line
options, the most important option is the d switch that triggers debug
information. For example, a command of:
slapd -d 256
would start OpenLDAP with a debug level of 256, as shown in the following
screenshot:
Note: For details about slapd options and their meanings, refer to the
OpenLDAP documentation.
Chapter 10. LDAP Server Configuration
91
Customizing the OpenLDAP Schema
The schema that slapd uses may be extended to support additional syntaxes,
matching rules, attribute types, and object classes.
In the case of the SN3101, the objectclass and attributeTypes configuration file
directives are used to define new schema. The extended schema file used to
authenticate and authorize users logging in to the SN3101 is shown in the
figure, below:

LDAP DIT Design and LDIF File
LDAP Data Structure
An LDAP Directory stores information in a tree structure known as the
Directory Information Tree (DIT). The nodes in the tree are directory entries,
and each entry contains information in attribute-value form. An example of the
LDAP directory tree for the SN3101 is shown in the figure, below:
(Continues on next page.)
Chapter 10. LDAP Server Configuration
93
(Continued from previous page.)
DIT Creation
The LDAP Data Interchange Format (LDIF) is used to represent LDAP entries
in a simple text format (please refer to RFC 2849). The figure below illustrates
an LDIF file that creates the DIT for the SN3101 directory tree (shown in the
figure, above).
SN3101 User Manual
94
Using the New Schema
To use the new schema, do the following:
1. Save the new schema file (e.g., sn3101.schema) in the
/OpenLDAP/schema/ directory.
2. Add the new schema to the slapd.conf file, as shown in the figure, below:
3. Restart the LDAP server.
4. Write the LDIF file and create the database entries in init.ldif with the
ldapadd command, as shown in the following example:
ldapadd -f init.ldif -x -D "cn=Manager,dc=aten,dc=com"
-w secret

IP Address Determination
If you are an administrator logging in for the first time, you need to access the
SN3101 in order to give it an IP address that users can connect to. There are
two methods to choose from. In either case, your computer must be on the same
network segment as the SN3101.After you have connected and logged in you
can give the SN3101 its fixed network address. SeeNetwork, page 16 for
details.
Method 1:
For computers running Windows, an IP address can be assigned with the IP
Installer utility:
1. Go to the Support and Downloads tab of the device product page on the
ATEN website (www.aten.com). Find the IP Installer download.
2. Download the zip file.
3. Extract the file (in the format IPInstaller.exe) to a suitable location and
execute it. A dialog box similar to the one below appears
:
4. Select the SN3101 in the Device List.
Note: 1. If the list is empty, or your device doesn't appear, click
Enumerate to refresh the Device List.
Appendix

2. If there is more than one device in the list, use the MAC address
to pick the one you want. The SN3101’s MAC address is located
on its bottom panel.
SN3101 User Manual
104
5. Select either Obtain an IP address automatically (DHCP), or Specify an
IP address. If you chose the latter, fill the IP Address, Subnet Mask, and
Gateway fields with the information appropriate to your network.
6. Click Set IP.
7. After the IP address shows up in the Device List, click Exit to end the
program.
Method 2:
1. Set your computer's IP address to 192.168.0.XXX
Where XXX represents any number or numbers except 10. (192.168.0.60 is
the default address of the SN3101.)
2. Specify the switch's default IP address (192.168.0.60) in your browser, and
you will be able to connect.
3. Assign a fixed IP address for the SN3101 that is suitable for the network
segment that it resides on.
4. After you log out, be sure to reset your computer's IP address to its original
value.
