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.)

Figure 1.

Model 2120 showing location of Ethernet and RS-232 ports.

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.

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.

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

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 boot - Boot System configure - Configure Parameters eiaconclose - EIA232 Connection Close ftp - FTP To Remote Device ping - Ping Remote Device rawtcp - Raw-TCP To Remote Device show - Show Parameters and Statistics telnet - Telnet To Remote Device

TS>

) 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.

Figure 5.

Model 2120 Help Menu/Command Hierarchy

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:

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.

6. Press the <Enter> key to see the main help menu screen.

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.

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

of application, the SLIP connection is usually terminated once the user is ﬁnished accessing the LAN/Internet.

Password

Each user in the 2120 user database is assigned a password for security purposes. The password may be up to 32 characters long.

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

Total Users = 3

TS>

Total Users = 2

TS>

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 ex ecuting 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.

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 f ollo wing 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>

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 f ollo wing commands at the 2120 command system prompt:

TS>configure eia232 interface subnetcfg <Subnet Mask of LAN><Enter> TS>configure activate

activate is complete!

TS>

3.9 NAME SERVERS

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 ex ecuting the follo wing commands at the 2120 command system prompt:

TS>configure eia232 ppp pridnsaddr <Address of Primary DNS><Enter> TS>configure eia232 ppp secdnsaddr <Address of Secondary DNS><Enter> TS>configure eia232 ppp peernsaddruseena no TS>configure activate

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 ex ecuting the follo wing 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 eia232 ppp peernsaddruseena no 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:

TS>configure eia232 ppp peernsaddruseena yes TS>configure activate

activate is complete!

TS>

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 pro vided 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.

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.

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 100-240V AC. This pow er 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 v ersion of the Model 2120. The black and red leads plug into a DC source (nominal 48VDC) and the barrel power connector plugs into the barrel power supply jack on the 2120 (see Figure 11).

Figure 13. Model 2120 Top Panel LEDs

Table 3: Model 2120 Top Panel LED deﬁnitions

LED Description

TXD Blinks green to show that data is being transferred through the unit. RXD Blinks green to show that data is being received.

Note The TXD and RXD LED’s indicate activity on either pin 2 or pin 3 on the

DB-25 connector depending on DTE/DCE mode.

DTR Glows yellow to indicate that the Data Terminal Ready signal is being detected

by the Terminal Server.

RTS Glows yellow to indicate that the Request to Send signal is being detected by

the T erminal Server.

CTS Glows yellow to indicate that the Clear to Send signal is being detected by the

Terminal Server.

DCD Glo ws yellow to indicate that the Data Carrier Detect signal is being detected by

the T erminal Server.

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 buff ers o verﬂow . 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 con-

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.

5.4 2120 UTILITIES

The Model 2120 features integrated utility f eatures to perform a variety of functions from the Model 2120 command system prompt.

Boot

The "boot" command allows the Model 2120 to be rebooted remotely over the LAN. When performed, the remote connection to the Model 2120 is lost. The following illustrates how to issue the "boot" command:

TS> boot<Enter> (or "b<Enter>")

EIA232 Connection Closure

The "eiaconclose" allows an administrative user to manually disconnect or close a user connection on the Model 2120 serial interface. The following illustrates how to issue the "eiaconclose" command:

TS> eiaconclose<Enter> (or "e<Enter>")

EIA connection close complete!

Ping

The "ping" command allows connectivity to be tested between the Model 2120 and a remote IP device. The following illustrates using the "ping" command:
