User’s Manual
1. Introduction
This User’s Manual describes the operation of the ESERV-10, ESERV-10S, ESERV-10S Bridge
and ESERV-10 OEM device servers. All devices are referred to in this User’s Manual as ESERV-
10, unless otherwise mentioned.
ESERV-10 is designed to offer transparent connection between a serial device and Ethernet
without the need to modify the existing design of the device. With ESERV-10 manufacturers and
system suppliers can connect their products such as home and industrial automation devices,
measuring devices and sensors through Ethernet to Internet. Devices can be controlled and
monitored using a standard Web browser (Internet Explorer, Netscape Navigator), a Telnet
connection or some other programs with a TCP/IP connection.

•Software updates and configuration over the Internet
•Motion sensors
•Remote control of display boards
•Global follow-up of systems
•Replacement of serial cable network with ready-made Ethernet network
ESERV-10 7 Viola Systems Ltd.

User’s Manual
ESERV-10 device server works in three different operating modes, each of which put emphasis on
a particular functionality. First, ESERV-10 is able to operate as a serial device server in both server
and client modes. Second, ESERV-10 functions through sending and receiving e-mail by using
SMTP (Simple Mail Transfer Protocol) and POP3 (Post Office Protocol) protocols, either
automatically or manually. Third, the remote control of ESERV-10 can be easily performed over the
network or locally with AT commands like in modems.
ESERV-10 device server includes the core protocols of TCP/IP and a built-in Web server. The
Internet Protocol (IP) is used for network communications and the Transmission Control Protocol
(TCP) to assure that no data is lost or duplicated, and that everything sent to the connection arrives
correctly at the target. The built-in Web server uses a graphic Java applet, which downloads from
the device server to the browser. This applet works as a virtual user interface for the device.
ESERV-10 device server can handle all Internet related functions by acting as a modem towards
the device connected to a serial port.
Internal Software
ESERV-10’s internal software consists of a TCP/IP stack, an embedded HTTP/Web server and
application software for a serial device connectivity.

2. Operation of ESERV-10
The ESERV-10 device server consists of a 16-bit RISC processor, a 130-kByte Flash-memory for
Web-pages, an Ethernet controller with 10 Mbps RJ45 network interface and a serial port driver
with RS-232 or RS-422/485 interface. The following figure shows the block diagram of ESERV-10.
A more detailed technical specification of the device is given in the Appendix 1.

The operation of ESERV-10 can be divided into following categories:
•Connection via the Internet to a serial port
•Web server
A detailed look to the available server modes of the ESERV-10 is given in the Appendix 2.
Connection via Internet to Serial Port
ESERV-10 device server operates as an invisible modem from the serial device’s point of view.
ESERV-10 processes the data received from the Internet so that only the “payload” is directed into
the serial port without the Ethernet or TCP/IP parts. The data from the serial port is encapsulated by
ESERV-10 into the TCP/IP protocol and transmitted forward through Ethernet. Connection to the
serial port can be achieved via the Internet with TCP and UDP through a configurable port.
IP TCP/UDP DATA
Local Network / Internet
ESERV-10
DATA
Serial Device
Transmission Control Protocol (TCP) is a so-called virtual circuit / connection-oriented protocol that
establishes a fixed virtual connection between two devices. TCP takes care of the entireness of the
data by using checksum and data transmission which use automatic handshakes. Since TCP
establishes a fixed connection between devices, the serial port can only be used from one TCP
connection at a time. The TCP protocol is used, for example, in the Telnet program.
ESERV-10 9 Viola Systems Ltd.

User’s Manual
User Datagram Protocol (UDP) is a connectionless protocol that doesn’t require specific opening or
closing of the connection. UDP also uses checksum to ensure the entireness of the data, but it
doesn’t automatically take care of retransmission and it doesn’t ensure the receiving of the data.
UDP is less secure than TCP, but it is lighter and, therefore, more useful for general-purpose
applications. Since UDP doesn’t require a fixed connection, several Internet devices can use the
serial port simultaneously. ESERV-10 operates so that it transmits all the data coming to UDP port
(which is configurable) to that IP address from which a connection has lastly been established. Due
to that, ESERV-10’s UDP implementation is well suited for question-answer -type data
transmission, in case the retransmission feature is already built-in (which is the case in most serial
protocols).
As a conclusion one could say that the use of UDP protocol is simpler and even recommended if
possible. Some firewalls prevent UDP connections due to security reasons since Windows
networks use it to share files. When using such programs as Telnet, or if the data transmission
should be ensured, TCP may be a better alternative. It should be noted that in both cases the
firewalls might prevent outgoing traffic. In such occasions the firewall must be configured to support
the ports and the IP addresses used by ESERV-10 if one prefers to establish a connection
outwards (from the Internet).
Web Server
ESERV-10 includes a Web server in the TCP port 80. HTML pages, figures, documents and Java
applets smaller that 130 kB can be downloaded into that port. After downloading, these files are
accessible with a standard Web browser (Internet Explorer or Netscape Navigator) by writing the
ESERV-10’s IP address and the filename, for example http://172.16.1.1/mypage.html. If the file is
not available, the unit will return an error page.
An access to the ESERV-10 without the filename (http:// 172.16.1.1) results in that the unit tries to
find the default page (index.html) from its memory. If this page is available, ESERV-10 returns it,
otherwise an error page is displayed.
The contents of Web pages can be created by using standard development tools. However, before
they are downloaded into the unit’s memory, separate files must be copied into one single file that
ESERV-10 recognizes. This can be done with a Viola Configurator program.
All kind of files can be downloaded into ESERV-10’s memory. The text database “mimetypes.txt” in
the Viola Configurator’s set up directory (for example C:\Program Files\Viola Configurator\) lists all
the file types that ESERV-10 recognizes. The database consists of the file type extension (like .txt)
and the corresponding MIME type (like text/plain). It is possible to add more file types into the
database.
Web server can be used to save a HTML page, which includes a Java applet. That can be
downloaded into the user’s Web browser and it can be used as a virtual user interface in the
following manner:
1. User types ESERV-10’s address in the browser’s address field.
2. ESERV-10 returns the HTML page including the Java applet.
3. The applet runs in the user’s browser without reducing the processing capacity of
ESERV-10.
4. The applet makes a TCP or a UDP connection to ESERV-10’s configurable port, enabling
information transmission over the Internet between the applet and the serial port.
ESERV-10’s Web server supports 10 simultaneous connections. To ensure maximum capacity, the
number of objects (pictures, HTML pages, applets) should be limited to 10.

4. Getting Started
Installation of the Device
The installation and operation of the ESERV-10 consist of the following steps:
1. Device connection
2. Setting up the IP address and the parameters
3. Checking the network connection
The ESERV-10’s IP address must be configured before a network connection is available. In this
Chapter the use of the Viola Configurator is described. The Viola Configurator is a tool for device
configuration and control. With this program you can manually assign the addresses, and set up or
control all parameters of ESERV-10. The Viola Configurator operates in Windows 95/98, 2000, NT
and ME environments.
The Viola Configurator is the most recommend tool for address assignment. However, there are
other options available. These options include Serial port login, ICMP Ping, BOOTP and Telnet
login. These features are discussed in the next Chapter ESERV-10 Configuration.
Before starting installation you need to know:
1. The Ethernet (MAC) Address. This is given in a product information label under the
ESERV-10. The address is of type 00:06:70:xx:xx:xx.
2. IP Address. The network administrator can provide the IP address or you can ask your
Internet Service Provider.
3. Subnet Mask. Typically you can use a class C network mask: 255.255.255.0. Check your
network administrator.
The following Section gives a brief look to the addresses related to internetworking. If you are
familiar to them you can skip to the Section Connect the Device.
Addresses Related to Internetworking
Ethernet Address (MAC)
The Ethernet address (MAC, Medium Access Control) is used in broadcast networks and is the
method determining which device has access to the transmission medium at any time. The address
consists of six bytes (each byte separated by a colon or dash) of which the first three are fixed and
read 00:06:70, identifying the unit as a Viola System product. The last three bytes are unique
numbers assigned to each unit. An example of the Ethernet address is 00:06:70:00:03:00.
Internet Protocol (IP) Address
The TCP/IP standard protocol defines the IP datagram as the unit of information passed across an
internet and provides the basis for connectionless, best-effort packet delivery service. In order to
operate in IP network every device must have a unique IP address. This is a 32-bit address
assigned to each host that participates in a TCP/IP internet. Usually the IP address is given in a
dotted decimal representation, for example: 172.16.8.10
ESERV-10 14 Viola Systems Ltd.

User’s Manual
Subnet Mask
Subnet mask is a bit mask used to select the bits from an IP address that correspond to the subnet.
Each mask is 32 bits long, with one bits in the portion that identifies a network and zero bits in the
portion that identifies the host. Like the IP address the subnet mask is given in dotted decimal
notation, making it easy to write and understand. Typical cases are a mask for a class C network:
255.255.255.0 and for a class B network: 255.255.0.0.
Port Number
UDP (User Datagram Protocol) allows an application program on one machine to send a datagram
to an application program on another. UDP uses the Internet Protocol to deliver datagrams.
Conceptually, the important difference between UDP datagrams and IP datagrams is that UDP
includes a protocol port number, allowing the sender to distinguish among multiple destinations
within a given remote machine.
TCP/IP protocols identify ports using small positive integers. Usually, the operating system allows
an application program to specify which port it wants to use. Some ports are reserved for standard
services. For example, a Telnet application commonly uses port number 23. ESERV-10’s serial port
can be associated with a configurable TCP/UDP port number the default being 7001.

1. Connect the serial device to the ESERV-10. Detailed description about the connectors is
given in Chapter Connectors and Switches.
2. Connect the Ethernet cable to the ESERV-10’s RJ45 Ethernet connector. ESERV-10 can
be configured either via a local network (LAN) or directly from PC. Depending on your
choice connect the other end of the Ethernet cable to the LAN or PC’s network interface
card.
Note: You must use a cross-connected cable (typically this cable has red connectors) if you
connect the ESERV-10 to the PC’s network interface card. If the board is connected to a
local network, a direct Ethernet cable must be used.
3. Check that all DIP switches are in the OFF position. This will allow a normal operation of
the ESERV-10 in the RS-232 mode.
4. Connect the power supply.
Note: When ESERV-10 is started for the first time it creates FL
A
SH file system to the
parameter memory and initialises the parameters to the default values. This process takes
about 20 seconds during which time the ESERV-10 does not respond to any kind o
f
commands and configuration screen is unavailable. When this process is done once,
ESERV-10 will start up in one second.

This configuration is stored in ESERV-10’s nonvolatile memory (except in Ping case). The device
configuration can be carried out either locally or remotely using the following procedures:
Method Description
Viola Configurator You can manually assign the IP address and device parameters using a
graphical user interface.
You need a PC and the ESERV-10 must be connected to the network or
directly to the PC.
ICMP “Ping” Assigns a temporary IP address after which Telnet login is available
Telnet Login You can assign the IP address and other network settings at a command
prompt using a Windows or UNIX-based system.
Serial Port Login You can manually configure the ESERV-10 through a serial port.
The description of the key parameters of ESERV-10 is given in the Appendix 2. The following
Sections describe how to configure the unit using the procedures mentioned above. It is possible to
change configuration at any time.
Note: ESERV-10 has easy-to-use security features for protecting unauthorized configuration and
possibility to limit configuration from network. In critical applications it is recommended to
turn these features on.
Configuring Using Viola Configurator
The Viola Configurator is an effective tool to set-up and to control the parameters of the ESERV-10.
In the following it is assumed that you have already defined the device addresses using the Viola
Configurator. If this is not the case or if you are going to configure ESERV-10 device servers
already existing in the network please run the Viola Configurator and define the device addresses
by using the procedures described in the previous Chapter. After the address definitions you can
retrieve current parameters of the device by clicking Retrieve parameters -icon in the Viola
Configurator’s taskbar.
When Viola Configurator is running, the normal procedure for setting up the parameters consists of
the following steps:
1. Double-click that parameter in the Name column of the Viola Configurator you want to
change. A Change parameter value window for that parameter appears.
Example of the window for setting the ESERV’s e-mail address:
2. Enter the value for that parameter or choose it from the options available. Press OK.
3. Repeat steps 1 and 2 until all the parameters you want to modify are set.
4. Send new parameters to the device by clicking Send parameters -icon.
