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 versatile 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.)
Figure 1. Model 2120 showing location of Ethernet and RS-232 ports.
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 over 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 exception, Raw-TCP contains all the features
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 exchange IP packets 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 packets 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 features 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. Switch set SW1 location
Figure 3. 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:

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 parameters.
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 switch 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 (TS>) appears, the main help menu (see Figure 4) will be
displayed by pressing the <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 executing 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 by typing the appropriate command or commands at the system prompt (TS>) followed by 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 must be entered in order to activate the changes and
write them to flash memory. 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!

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.

3.6 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 device 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 packets 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.

RawTCP Operation
In the typical RawTCP application (see Figure 7), the user has a need to
connect a network enabled software application to a remote serial device
over the LAN for standard operation of the device. To enable the software application to communicate with the remote serial device, the
Model 2120 is usually assigned a static IP Address and the IP Address is
configured within the software application. When the software application is launched, it sends data in TCP packets over the LAN to the IP
Address of the Model 2120. When received, the Model 2120 converts
the packets to asynchronous data and forwards the data to the device
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 packets and sends it over the LAN back to the originating location/
application to complete the cycle. In this type of application, the RawTCP connection between the software application and Model 2120 is
configured so that is does not timeout/disconnect.
Note
Legacy software applications that are not network enabled will
require a Comm Port Redirector application to communicate
with the Model 2120 and the remote serial device over the LAN.
A Comm Port Redirector is used to map serial communication
ports to the IP address and port number of the 2120 connected
to the remote serial device. This application resides on the computer hosting the legacy software application and basically tricks
the legacy application into packetizing the asynchronous data
into TCP packets and sending the data over the LAN to the IP
Address of the remote 2120/device, thus creating a transparent
serial connection.

PPP Operation
In the typical PPP application (see Figure 8), the user has a need to
remotely connect to a LAN for general access to the LAN (e-mail, applications, etc.) or for access to the Internet. To make this connection, the
user typically uses a dial-up modem with standard POTS line and
launches a PPP application to connect with a dial-up (or ISDN) modem
connected to the LAN. Once the connection is made between the PPP
dial-up peer and the modem, the Model 2120 serial interface will typically
obtain its operating IP address from an active DHCP server on the LAN
and then establishes a connection with the LAN. Once connected to the
LAN, the user is typically prompted to enter a user name and password
through the enabling of PAP user authentication protocol. When the correct user name and password are entered, the user is permitted access
to the LAN for general or Internet access. The data from the PPP application and LAN is converted into PPP packets and the data is moved
back and forth through the established PPP connection and over the
LAN. For domain name resolution, the Model 2120 is typically configured for DNS with the addresses of a primary and secondary DNS. In
this type of application, the PPP connection is usually terminated once
the user is finished accessing the LAN/Internet.

SLIP Operation
In the typical SLIP application (see Figure 9), the user has a need to
remotely connect to a LAN for general access to the LAN (e-mail, applications, etc.) or for access to the Internet. To make this connection, the
user typically uses a dial-up modem with standard POTS line and
launches a SLIP application to connect with a dial-up (or ISDN) modem
connected to the LAN. Once the connection is made between the SLIP
and the modem, the Model 2120 will establish a connection with the LAN
using a static IP address assigned by the Network Administrator. Once
connected to the LAN, the user is permitted access to the LAN for general or Internet access (SLIP will require user name put in 2120 database if there is one). The data from the SLIP client application and LAN
is converted into SLIP packets and the data is moved back and forth
through the established SLIP connection and over the LAN. For domain
name resolution, the Model 2120 must obtain name server addresses
from the SLIP client device connected to the serial interface. In this type
35
of application, the SLIP connection is usually terminated once the user is
finished accessing the LAN/Internet.

3.7 USER DATABASE
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.
User Name
The user name uniquely identifies each user in the 2120 user database.
The user name may be up to 32 characters long.
Password
Each user in the 2120 user database is assigned a password for security
purposes. The password may be up to 32 characters long.
38
Privilege
Each user in the 2120 user database is assigned a privilege that identifies how each user may interact with the Model 2120. The three types of
privileges that exist in the Model 2120 are defined as follows:
User - The User privilege permits a user to access only the serial
interface. If the Model 2120 is configured for Telnet / TCP or RawTCP operation, the user may connect to serial interface over the
LAN and receive/transmit data. 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 interface of the Model 2120 and receive / transmit data over the LAN.
Admin - The Admin privilege permits a user to access only the
administrative management and configuration/status functions of
the Model 2120 over the LAN via Telnet session.
Both - The Both privilege provides a user with both User and Admin
privileges.
Creating Users
Creating a user is accomplished by executing the following command at
the 2120 command system prompt:
TS>configure userdatabase createuser username,password,privilege<Enter>
Some examples of creating users are as follows:
TS>configure userdatabase createuser
john,1234abc,user<Enter>
TS>configure userdatabase createuser
al,blue,admin<Enter>
TS> configure userdatabase createuser
tom,98lk12,both<Enter>
TS>configure activate<Enter>
activate is complete!
Viewing the active users in the 2120 user database is accomplished by
executing the following command at the 2120 command system prompt:
TS>show userdatabase all<Enter>
--> User Database <-john,1234abc,user
al,blue,admin
tom,98lk12,both
39
Total Users = 3
TS>
Deleting All Users
Deleting all users is accomplished by executing the following commands
at the 2120 command system prompt:
TS>configure userdatabase deleteall<Enter>
TS>configure activate<Enter>
activate is complete!
Verifying that all active users have been deleted from the user database
is accomplished by executing the following command at the 2120 command system prompt:
TS>show userdatabase all<Enter>
user database empty!
TS>
Deleting A Single User
Deleting a single user is accomplished by executing the following commands at the 2120 command system prompt:
TS>show userdatabase all<Enter>
--> User Database <-john,123abc,user
al,blue admin,user
tom,98lk12,both
Total Users = 3
TS> configure userdatabase deleteuser al<Enter>
TS> configure activate<Enter>
activate is complete!
Verifying that the user has been deleted from the user database is
accomplished by executing the following command at the 2120 command system prompt:
TS>show userdatabase all<Enter>
40
--> User Database <-john,123abc,user
tom,98lk12,both
Total Users = 2
TS>
Modifying A User
Modifying a user's password or privilege is accomplished by executing
the following commands at the 2120 command system prompt:
TS>show userdatabase all<Enter>
--> User Database <-john,123abc,user
tom,98lk12,both
Total Users = 2
TS>configure userdatabase modifyuser
tom,98lk12,admin<Enter>
TS>configure activate<Enter>

Total Users = 2
TS>
41
3.8 IP ADDRESSING
Unit IP Address
The IP address used to manage the Model 2120 unit can be configured
statically or dynamically. The Model 2120 is defaulted to use DHCP
(Dynamic Host Configuration Protocol) to dynamically obtain the unit IP
address over the LAN from an active DHCP server. When using DHCP,
the 2120 sends the DHCP server MAC address information and dynamically obtains its IP address based on the unit MAC address (factory configured). This feature reduces the number of IP addresses on the
network and minimizes network administration.
Enabling DHCP to dynamically obtain the unit IP address is accomplished by executing the following commands at the 2120 command system prompt:
TS>configure system dhcpena yes<Enter>
TS>configure activate<Enter>
activate is complete!
TS>
For applications that require a static IP address for the Model 2120 unit,
an assigned IP address is obtained from your Network Administrator,
and is configured by executing the following commands at the 2120 command system prompt:
TS>configure system ipaddrcfg <assigned IP
address><Enter>
TS>configure system dhcpena no<Enter>
TS>configure activate<Enter>
activate is complete!
TS>
Serial Interface IP Address
When operating in Telnet and Raw-TCP modes, the Model 2120 uses the
active unit IP address (static or dynamic) as the serial interface IP
address. These modes use a TCP port number to differentiate between
the unit and serial interface and do not consume a second IP address.
When operating in PPP mode, the serial interface IP address can be
configured statically or dynamically using a DHCP server. Further, the
PPP IP address may be obtained from the PPP dial-up device connected
to the serial interface.
42
For PPP applications that require a static IP address for the serial interface, an assigned IP address is obtained from your Network Administrator, and is configured by executing the following commands at the 2120
command system prompt:
TS>configure eia232 interface ipaddrcfg <assigned IP
address><Enter>
TS>configure eia232 ppp dhcpena no<Enter>
TS>configure activate<Enter>
activate is complete!
TS>
The Model 2120 is configured for PPP applications that require the serial
interface IP address to be dynamically assigned by a DHCP Server by
executing the following commands at the 2120 command system prompt:
TS>configure eia232 ppp dhcpena yes<Enter>
TS>configure activate<Enter>
activate is complete!
The Model 2120 may also obtain the serial interface IP address from the
PPP client device connected to the serial interface. In this scenario,
every time a PPP client establishes a PPP connection, the Model 2120
will use the IP address provided by the PPP instead of a static or
dynamic IP address. PPP IP addressing is configured by executing the
following commands at the 2120 command system prompt:
TS>configure eia232 ppp peeripaddruseena yes<Enter>
TS>configure activate<Enter>
activate is complete!
When operating in SLIP mode, the serial interface IP address must be
configured the same as the IP address assigned to the device connected
to the serial interface. The static serial interface IP address for SLIP
operations is configured by executing the following commands at the
2120 command system prompt:
TS>configure eia232 interface ipaddrcfg <IP address of
device connected to serial interface><Enter>
TS>configure eia232 ppp dhcpena no<Enter>
TS>configure activate<Enter>
activate is complete!
TS>
43
Subnet Mask
The Subnet Mask settings that correspond with the 2120 unit and serial
interface IP addresses should be configured with the appropriate Subnet
Mask for the LAN where the IP addresses reside.
The Subnet Mask for the Model 2120 unit is configured by executing the
following commands at the 2120 command system prompt:
TS>configure system subnetcfg <Subnet Mask of
LAN><Enter>
TS>configure activate<Enter>
activate is complete!
TS>
The Subnet Mask for the Model 2120 serial interface is configured by
executing the following commands at the 2120 command system prompt:
TS>configure eia232 interface subnetcfg <Subnet Mask of
LAN><Enter>
TS>configure activate
activate is complete!

When operating in PPP mode and accessing the Internet through the
Model 2120, the several options are available and supported 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.
Domain Name Server (DNS)
The Model 2120 supports DNS address exchange with the PPP device.
Primary and secondary DNS addresses can be configured for the PPP
client device. The primary and secondary DNS addresses are configured by executing the following commands at the 2120 command system
prompt:
TS>configure
DNS><Enter>
TS>configure
DNS><Enter>
TS>configure
TS>configure
eia232 ppp pridnsaddr <Address of Primary
eia232 ppp secdnsaddr <Address of Secondary
eia232 ppp peernsaddruseena no
activate
44
activate is complete!
TS>
Windows Name Server (WINS)
The Model 2120 supports WINS address exchange with the PPP device.
Primary and secondary WINS addresses can be configured for the PPP
client device. The primary and secondary WINS addresses are configured by executing the following commands at the 2120 command system
prompt:
TS>configure eia232 ppp priwinsaddr <Address of Primary
DNS><Enter>
TS>configure eia232 ppp secwinsaddr <Address of Secondary DNS><Enter>

TS>configure activate
activate is complete!
TS>
Obtaining Name Server Addresses From PPP Client
The Model 2120 may also obtain name server addresses from the PPP
device connected to the serial interface. Every time a PPP establishes a
connection, the Model 2120 will use the name server addresses provided by the PPP instead of the other configured name server addresses
(DNS and WINS). Obtaining name server addresses from the PPP/SLIP
is configured by executing the following commands at the 2120 command system prompt:
TS>configure eia232 ppp peernsaddruseena yes
TS>configure activate
activate is complete!
TS>
Obtaining Name Server Addresses From SLIP Client
When operating in SLIP mode, the Model 2120 must obtain name server
addresses from the SLIP device connected to the serial interface. Every
time a SLIP establishes a connection, the Model 2120 will use the name
server addresses provided by the SLIP. Obtaining name server
addresses from the SLIP is configured by executing the following commands at the 2120 command system prompt:
45
TS>configure eia232 ppp peernsaddruseena yes
TS>configure activate
activate is complete!

4.0 INSTALLATION
Once the Model 2120 is configured, it is ready to connect to the serial
interface of the RS-232 device, to the Ethernet interface, and to the
power source. The Model 2120 is designed to connect an asynchronous
RS-232 device to other devices via the LAN/10Base-T interface. This
section describes how to install the 2120.
4.1 MODEL 2120 CONNECTION
The Model 2120 features DB-25 (Male or Female), DB-9 (Male or
Female), and RJ-45 serial interface connectors and a standard RJ-45
Female Ethernet interface connector. With the DB-25 connector and
connector screws, the 2120 conveniently attaches and secures to the
serial port of the RS-232 device. The DB-9 version features an RJ-45
Female connector and 6" adapter cable with DB-9 (M or F) connector on
the serial side, which allows the 2120 to conveniently attach to the DB-9
serial port of the RS-232 device and can be mounted/secured on or near
the RS-232 device. The RJ-45 connector on the serial side allows for a
convenient connection with a patch cable (not provided with 2120) to RS232 control ports and other devices with RJ-45 serial ports. The 2120
connects to any standard LAN connection (usually an RJ-45F connector)
using a standard LAN patch cord (not provided with 2120).
In Figure 10, the Model 2120 is attached directly to a card reader and will
use its individually assigned IP address so that the host PC can communicate with the card reader over the Ethernet LAN. Using a communications protocol such as Telnet or Raw-TCP, the host PC will poll and
monitor the card reader for various types of data.
Figure 10. A Typical RS-232 to 10BaseT Ethernet Installation
4.2 AC POWER CONNECTION
The Model 2120 is offered with either an AC or DC power supply. This
section briefly describes the power supplies and connections to the
Model 2120 and the power source. The Model 2120 is powered-up as
soon as it is plugged into an AC outlet (there is no power switch). The
2120 features an LED indicator for Power and when lit, the 2120 is
receiving power from the power supply.
49
AC Power Supply (100-240VAC)
The Model 2120/??/UI uses a +5VDC, 2A universal input, power supply
that is equipped with a male IEC-320 power entry connector and supports a voltage range of 100-240VAC. This power supply connects to the
Model 2120 by means of a cannon jack on the rear panel. There are a
variety of domestic and international power cords available for power
entry.
DC Power Supply (36-60VDC)
The 36-60 VDC DC to DC adapter is supplied with the DC version of the
Model 2120. The black and red leads plug into a DC source (nominal

Note When there is no connection to the DB-25 side of the unit, the CTS,
RTS, and DCD LED’s stay lit at all times.
PWR
Glows green to indicate that power is applied to the unit.
Note
The DCD LED is an indicator of whether the 2120 is configured
for DCE or DTE operation. When configured for DCE, the DCD
LED will glow constantly except for when a session is being terminated. When configured for DTE, the DCD LED will only glow
when a connection is established with the serial interface.
5.2 FLOW CONTROL AND SESSION CONTROL
Flow Control
Flow control settings control the flow of data between the Model 2120
and the device connected to the serial interface. The Model 2120 can be
configured for DCE or DTE operation.
With hardware flow control selected, the RTS (Request To Send) and
CTS (Clear To Send) signals control the flow of data between the Model
2120 and the device connected to the serial interface. RTS originates
from the DTE and is an input to the DCE. CTS originates from the DCE
and is an input on the DTE. When the Model 2120 is configured for DCE
operations, the DTE will turn RTS ON to indicate the 2120 to send data
to the DTE and OFF to stop the 2120 from sending data before the DTE
receive buffers overflow. The 2120 (DCE) will turn CTS ON to allow the
DTE to transmit data and OFF to stop the DTE from sending data before
the 2120 receive buffers overflow. The opposite is true when the 2120 is
configured for DTE operations.
With xon/xoff (software) flow control selected, the flow of data between
the Model 2120 and the device connected to the serial interface is con53
trolled by two ASCII characters, 0x11 (XON) and 0x13 (XOFF). These
characters are fixed and not configurable in the Model 2120. The XON
and XOFF characters are simply sent through the data stream, in other
words, they look like data. To stop receiving data, XOFF is sent to the
sender and the sender stops sending data until it receives an XON (in
most cases).
When no (none) flow control is selected, the flow of data between the
Model 2120 and the device connected to the serial interface is not managed, therefore, it is possible for the buffers to overflow causing the loss
of data.
Session Control
Session control is essential for PPP and SLIP applications. A PPP/SLIP
session must be terminated before the user leaves, otherwise another
user may continue in that same session, which is not good from a security standpoint. The DTR (Data Terminal Ready) and DSR (Data Set
Ready) control signals are used for terminating a SLIP or PPP session.
If the user is configured for DTE operations and wishes to disconnect the
session, the DTE will turn DTR off for 2 seconds. If the user configured
is for DCE operations, the DCE will turn DSR off for 2 seconds to terminate SLIP and PPP connections.
5.3 USING "SHOW" COMMANDS FOR 2120 STATUS
The Model 2120 features the ability to remotely execute and view any or
all configuration parameter settings and operational status of the Model
2120 unit by using the system "show" commands. For a detailed definition of all 2120 system show commands, see Appendix B on page 59.
