2.3 DESCRIPTION
The Model 2120 Single Port Terminal Server (see Figure 1) provides a
quick, easy to use solution for connecting traditional RS-232 terminals
and devices to the Local Ethernet/IP Network. The Model 2120 can also
function as a very cost effective single port remote access server. Serial
asynchronous device connectivity across the LAN is provided using Telnet/TCP, Raw-TCP, SLIP, or PPP protocols. The v ersatile and feature-rich
Model 2120 can literally be used in thousands of different applications
and environments, including:
• Factory floor machinery
• Security systems
• Printers
• Scales
• Barcode scanners
• Various instruments
• Climate control systems
• ASCII terminals
• Vending machines
• Cash registers and other point-of-sale (POS) devices
• RS-232 control/console ports (PBX, switches, etc.)

12
The Model 2120 is initially configured via the serial interface using a
dumb terminal or terminal emulation software in VT-100 mode. The serial
interface factory default asynchronous setting is 9600 bits/second, 8 bits
per character, no parity, and 1 stop bit. All configuration parameters can
be set via the serial interface using the 2120's menu-driven command
system. Once initial configuration is complete with a static or dynamically assigned IP address and the 2120 is connected to the LAN, configuration parameters can be modified, configuration parameters and
operational status can be viewed, and utilities can be performed ov er the
LAN using a Telnet session.
The Model 2120 can use DHCP (Dynamic Host Configuration Protocol)
to dynamically obtain the unit IP address over the LAN from a DHCP
server. The 2120 sends the DHCP server MAC address information and
dynamically obtains its IP address based on the unit MAC address. This
feature reduces the numbers of IP addresses on the network and minimizes network administration.
Telnet/TCP operation provides an asynchronous device connected to the
Model 2120 serial interface with connectivity to a remote device/application over the LAN. Asynchronous data received at the Model 2120 serial
interface is sent to the remote device using the Telnet/TCP protocol.
Asynchronous data received from the Telnet/TCP connection is sent to
the device connected to the Model 2120 serial interface. When the
remote device accessed over the LAN performs the same type of operation, an asynchronous connection is formed between the two devices.
Raw-TCP operation is identical to Telnet/TCP operation with one exception. The data passed between the 2120's serial interface and the
remote device/application is directly passed using TCP (Telnet is not
used). Aside from this one e xception, Ra w-TCP contains all the f eatures
and functionality as Telnet/TCP.
PPP operation provides an asynchronous device connected to the Model
2120 serial interface with LAN connectivity. The Model 2120 and the
device connected to its serial interface e xchange IP pac kets where each
IP packet is PPP encapsulated. The Model 2120 uses proxy ARP to provide the device connected to the serial interface with a virtual LAN connection. The Model 2120 optionally provides PAP as a user
authentication protocol. PAP security can be used to validate a user trying to establish a LAN connection from the device connected to the
Model 2120 serial interface. The Model 2120 IP address for PPP operations can be either configured statically or dynamically using a DHCP
server. Further, the PPP IP address may be obtained from the PPP client device connected to the serial interface.
13
SLIP operation provides a device connected to the Model 2120 serial
interface with LAN connectivity. The Model 2120 and the device connected to the serial interface exchange IP pack ets where each IP packet
is SLIP encapsulated. The Model 2120 uses proxy ARP to provide the
device connected to the serial interface with a virtual Ethernet connection. The Model 2120 serial interface IP address must be configured with
the same static IP address as the device connected to the serial interface.
When operating in PPP mode and accessing the Internet through the
Model 2120, the unit can be configured for DNS and/or WINS . These are
client name server options for Internet domain name resolution. When
operating in SLIP mode, the Model 2120 must be configured to obtain
the name server addresses from the SLIP client device.
The Model 2120 features a flexible user database with security for up to
64 users. This enables security access to the Model 2120 serial interface and administrative management of the Model 2120 over the LAN.
Each user is assigned a user name, password and privilege for accessing the serial interface (User), administration management features
(Admin), or both. If the Model 2120 is configured for PPP (and PAP
security is enabled), the user may connect from a remote PPP client
through a modem connected to the serial port of the Model 2120 and
receive / transmit data over the LAN.
The Model 2120 uses an integrated FTP (File Transfer Protocol) client to
obtain new program images and communicate with an FTP server. The
FTP client logs onto the FTP server and then can browse and display
files located on the FTP server. The FTP client can also obtain a new
program image (software release) from the FTP server. The program
image is first obtained from the FTP server across the LAN and then
stored in FLASH memory. This enables the Model 2120 to obtain new
functionality both easily and quickly. The latest Model 2120 software
release is available for download via upgrades.patton.com.
The Model 2120 features integrated utility f eatures to perform a variety of
functions. These include utilities to activate new software images (activateimage), remotely boot the Model 2120 over the LAN (boot), remotely
close the connection to the Model 2120 serial interface (eiaonclose), test
connectivity with another IP device (ping), establish a Telnet session with
another IP device with Telnet/TCP support (telnet), establish a Raw-TCP
session with another IP device with TCP support (rawtcp), and display
the Model 2120 ARP Table (za).
Last, the Model 2120 features the ability to view any or all configuration
parameter settings and operational status of the Model 2120 unit.

3.0 CONFIGURATION
3.1 CONFIGURATION SWITCHES
SW1 is a set of four internal DIP switches (see Figure 2) that are used for
configuration reset purposes only . To access switch set SW1, use a small
flat blade screwdriver to open the Model 2120’s case as shown in
Figure 3.
Figure 2.
Figure 3.
Switch set SW1 location
Opening the Model 2120 case
To configure the DIP switches, use a small screwdriver and gently push
each switch to its proper setting. The ON and OFF positions are shown in
Figure 2.
15
Default Settings
Default settings for the DIP switches are as follows:
Table 1:
Default Settings
Position Function Factory Default
SW1 Configuration Reset OFF
SW2 DCE/DTE on Config Reset OFF
SW3 Not Used (Must Be OFF) OFF
SW4 Not Used (Must Be OFF) OFF
Detailed Switch Settings
This section provides detailed information about the function of each DIP
switch and lists all possible settings.
• Switch 1: Configuration Reset. Set this switch to the ON position and
power cycle the unit to reset to the factory default configuration par ameters.
Note
This will not change the factory assigned NIC/MAC address.
• Switch 2: DCE/DTE on Configuration Reset. When a configuration
reset is being performed via Switch 1 (above), set this s witch to the ON
position to force the serial interface to DTE or to the OFF position to
force the serial interface to DCE.
Note
This switch is ONLY read when the configuration is reset
through Switch 1 (above).
• Switch 3: Not Used. This switch is not used and must remain in the
OFF position.
• Switch 4: Not Used. This switch is not used and must remain in the
OFF position.
3.2 SOFTWARE CONFIGURATION
The Model 2120 features a menu-driven command system that enables
the configuration of the 2120 software via the serial interface using a VT100 terminal or emulation session or over the LAN using a Telnet session. Since the Model 2120 is not pre-configured with an IP address for
your network, initial configuration of the Model 2120 is performed via the
serial interface (See “Initial Unit Configuration” on page 21.). Once initial
configuration is complete with a static or dynamically assigned IP
address and the Model 2120 is connected to the LAN, configuration
parameters can be modified over the LAN using a Telnet session. The
16
management enable command is factory set to yes, which allows the
remote configuration of the Model 2120 over the LAN.
Model 2120 Software Command System
The Model 2120 Software Command System is designed with a series of
help menus and commands derived from the actual function descriptions. Once a session has been established with the 2120 and the system prompt (
displayed by pressing the <
*** Help Menu ***
activateimage - Activate Image Acquired With FTP Get

) appears, the main help menu (see Figure 4) will be
Enter
> key.
Figure 4.
Main Help Menu
The "configure" and "show" commands are used to access system,
eia232 and user database related parameters. Commands other than
"configure" and "show" result in ex ecuting an operation or utility and thus
do not have menus associated with them.
Model 2120 Help Menu/Command Hierarchy
The help menu/command hierarchy is shown in Figure 5 on page 18.
Note
For a detailed definition of all Model 2120 system commands,
valid entries, and defaults see Appendix B on page 59.
17
Figure 5.
Model 2120 Help Menu/Command Hierarchy
18
Entering Commands
Commands are executed b y typing the appropriate command or commands at the system prompt (TS>) followed b y a valid entry (if applicable)
and the
<Enter>
key. If entering multiple commands, they must be entered
in hierarchy order (See “Model 2120 Help Menu/Command Hierarchy” on
page 17) and separated by a space. For example, the following command
string is entered to set the serial interface data rate to 115.2 kbps:
TS>configure eia232 interface datarate 115200<Enter>
For a single entry command such as “boot”, the following command is
entered to remotely boot the Model 2120:
TS>boot<Enter>
Commands entered are matched against the commands available for
that menu. Commands are accepted when the characters entered for a
command can only match one command for that menu. Thus shortcuts
are permitted when entering commands. The following examples show
how shortcut commands can be used to enter the same configure and
boot commands as listed above:
TS>c e i da 115200<Enter>
TS>b<Enter>
Activating Configuration Commands
The Model 2120 configuration parameters can be changed by using the
“configure” command and associated sub-commands. Immediately after
the necessary “configure” command string is entered, the “configure activate” command
write them to flash memory
must
be entered in order to activate the changes and
. For example, the command string used to
set the serial interface data rate to 115.2 kbps (see section “Entering
Commands”) must be immediately followed by the following command:
TS>configure eia232 interface datarate 115200<Enter>
TS>configure activate<Enter>
If successfully activated, the message “Activate is complete!” will display.
Note
The “configure activate” command MUST be entered after each
configuration change!

Note To reset the Model 2120 software to factory default settings, set
internal dip switch #1 to the ON position and power cycle the
Model 2120 unit. Once powered on, set switch #1 back to the
OFF position. This will reset all settings, with the e xception of the
unit MAC address, to the above listed factory defaults.
3.4 INITIAL UNIT CONFIGURATION
Unless pre-configured with an IP address for your LAN (not standard),
the Model 2120 must be initially configured via the serial interface using
the menu-driven command system and required terminal equipment as
described below:
21
1. Verify that the four internal DIP switches are set to the OFF position
(factory default).
2. Using ribbon cable or other similar cable, connect the serial RS-232
port of a VT-100 ASCII terminal or similar DTE with terminal emulation software to the RS-232 port of the Model 2120.
3. Power up the emulation device and configure its RS-232 port as
follows:
– 9600 Baud
– 8 data bits, 1 stop bit, no parity
– ANSI, VT100 emulation
4. Power up the Model 2120.
5. After the Model 2120 is powered on, the ASCII terminal or emulation
device should display the following message:
Model 2120 Terminal Server
Software Version ?.?.? (will display current version)
TS>
Note If you are unable to connect with the Model 2120 and you have
rechecked your terminal emulation settings, it is recommended
that a configuration reset (to factory defaults) be performed on
the Model 2120 by setting internal dip switch #1 to the ON position and power cycling the Model 2120. Once powered on, set
switch #1 back to the OFF position. If still unable to establish a
connection, please contact Patton Electronics Technical Support
at (301) 975-1007.

8. You are now ready to configure the Model 2120 for your application.
Configuration parameters will vary based upon the requirements of
each application.
For a detailed definition of all 2120 system commands, valid entries, and
defaults see Appendix B on page 59.
Note Contact your Network Administrator if you have questions
regarding configuration parameters required for your application
and/or LAN.
3.5 REMOTE CONFIGURATION OF THE UNIT
Once you have performed the initial configuration and the Model 2120 is
connected to and communicating with a LAN, the configuration parameters can be changed remotely from anywhere on the LAN using an FTP
Client (i.e. Windows Command Mode) on a computer that can communicate over the LAN.
1. From the Windows “Run” prompt at your computer, type: command
and click OK.
2. At the DOS prompt, Telnet into the 2120 by typing:
telnet <
the IP address of the 2120>
and pressing <Enter>.
3. When connected to the 2120, the computer should display the following message:
Model 2120 Terminal Server - Telnet Session
Software Version ?.?.? (will display current version)

3.6 SAMPLE 2120 CONFIGURATIONS
The Model 2120 features and functionality allow it to operate in thousands of different applications; however, this section is not intended to
cover all the possibilities. The configuration samples provided below will
describe some of the typical 2120 applications and the configuration settings required for proper operation and serve as a useful reference when
configuring the Model 2120 for your own application. This section will not
discuss in detail the serial devices connected to the Model 2120 and
related operating systems and/or applications. Actual configurations will
vary from application to application based on the requirements and configuration of the serial device and related operating systems and applications.
Telnet/TCP Operation
In the typical Telnet/TCP application (see Figure 6), the user has a need
to remotely connect to a serial device located on the LAN for administration, configuration, monitoring, troubleshooting, data collection, etc. To
enable the remote connection via Telnet session, the Model 2120 is usually assigned a static IP address. The user then launches a Telnet/TCP
session from their Computer specifying the IP Address of the Model
2120 and port number and remotely connecting to it over the LAN. Once
connected, the Telnet/TCP client converts the asynchronous data into
TCP packets and sends it over the LAN to the IP address of the Model
2120. When received, the Model 2120 converts the packets back to
asynchronous data and forwards the data to the de vice connected to the
serial interface. The serial device sends asynchronous data back to the
Model 2120 and the Model 2120 converts the data into TCP pac kets and
sends it over the LAN back to the originating Telnet/TCP client and is
converted to asynchronous data to complete the cycle. Once the
desired tasks are performed, the Telnet session is usually terminated.
