In addition, by making these industrial serial devices Internet ready, the SN3101 enables users to access and control those devices from any computer connected to the Internet, whether down the hall, or half way around the world.

The SN3101 offers versatile and diversified serial data access methods to meet a broad range of application requirements – these include Console Management, Real COM, TCP Server, TCP Client, UDP, Modbus, Serial Tunnel, and Virtual Modem. SMTP and SNMP trap event notification are also provided.

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 with the latest improvements simply by downloading updates from our website. With its advanced features and ease of operation, the SN3101 is the most convenient, most reliable, and most cost effective way to centrally manage your serial devices.

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 users’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 users’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 Direct Access function (see Direct

Access, page 46, for details).

SN3101 User Manual

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 SSL 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 Direct 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 SSL data encryption in this operating mode.

Chapter 5. Port Operating Modes

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

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 104.

Note: 128-bit SSL 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 master/slave relationship. One unit is designated master, the other designated slave.

Note: In this configu ration, it doesn’t matter which one is designated master

and which one is designated slave.

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 SSL data encryption is supported in this operating mode.

The process can run in either Interactive mode or Fast mode. With Interactive mode, users don’t specify any parameters on the command line. They make mapping/unmapping choices based on questions generated as the program runs.

With Fast mode, users specify parameters on the command line to indicate their mapping/unmapping choices – as shown in the following examples:

1. Mapping (input should all be on one line):

./AtenVPMapping map(1) PCPort(0-255) TargetIP(a.b.c.d) TargetPort(1-48) NumberofMapping(1-48)

2. Unmapping (input should all be on one line):

./AtenVPMapping unmap(0) PCPort(0-255) NumberofUnMapping(1-48)

Virtual Port Naming Rules

All of the ATEN SN virtual ports under Linux have the prefix ttya. Mapped virtual ports can be found in the /dev dir. They all have a prefix of ttya

(ttya000, ttya001, etc.). The range is from ttya000 – ttya255.

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 Schema 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.

The following section provides an example of configuring LDAP under Windows 2003 Server.

Install the Windows 2003 Server Support Tools

To install the Windows 2003 ServerSupport Tools, do the following:

1. On your Windows Server CD, open the Support

SN3101 User Manual

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:

192.168.0.80&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-0.9.8awin32_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 Components dialog box appears, select install BDB-tools and install OpenLDAP-slapd as NT service, as shown in the diagram, below:

Chapter 10. LDAP Server Configuration

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

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 ab out slapd options and their meanings, refer to the

OpenLDAP documentation.
