UDS2100 User Guide 8

22:: IInnttrroodduuccttiioonn

The UDS2100 is a 2-port device server that provides a quick, simple, and costeffective way to bring the advantages of data accessibility and remote management to devices not currently connected to a network.

Applications

The UDS family of Device Servers allows serial devices, such as those listed below, to connect and communicate over Ethernet networks using the IP protocol family (TCP for connection-oriented stream applications and UDP for datagram applications).

 Security alarms

 Access control devices

 Fire control panels

 Time/attendance clocks and terminals

 ATM machines

 Data collection devices

 RFID readers

 Universal Power Supply (UPS) management units

 Telecommunications equipment

 Data display devices

 Virtually any asynchronous RS-232, RS422, or RS485 device

Application Examples

Using a method called serial tunneling, the UDS encapsulates serial data into packets and transports them over Ethernet. Using two UDS units, connected by a network, virtual serial connections can extend across a facility or around the world.

UDS2100 User Guide 9

2: Introduction

Figure 2-1. Serial Tunneling Example

The Com Port Redirector software included on the product CD simplifies the integration process by extending the functionality of COM-port-based Windows™ applications. Virtual COM ports, mapped to remote device servers on the network, can replace direct serial connections.

Figure 2-2. Direct TCP/IP or Redirector Configuration

Note: For step-by-step instructions on configuring the UDS for seri al tunneling or for

use with the Com Port Redirector, see UDS Configuration Tutorials on the Lantronix web site:

www.lantronix.com/support.

UDS2100 User Guide 10

Protocol Support

The UDS uses the Internet Protocol (IP) 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.

Supported protocols include:

 ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP for

network communications.

 TCP, UDP, and Telnet for connections to the serial port.

 TFTP for firmware updates.

 IP for addressing, routing, and data block handling over the network.

 User Datagram Protocol (UDP) for typical datagram applications in which

devices interact with other devices without a point-to-point connection.

Additional Features

Modem Emulation: In modem emulation mode, the UDS can replace dial-up

modems. The unit accepts modem AT commands on the serial port and then establishes a network connection to the end device. This arrangement leverages network connections and bandwidth to eliminate dedicated modems and phone lines.

2: Introduction

Built-in Web Server: The UDS includes a built-in web server for configuring the unit

and displaying operating and troubleshooting information on the attached links to online support.

Configuration Methods

After installation, the UDS requires configuration. For the unit to operate correctly on a network, it must have a unique IP address on the network. There are three basic methods for logging into the UDS and assigning IP addresses and other configurable settings:

DeviceInstaller: Configure the IP address and other network settings on the UDS

using a Graphical User Interface (GUI) on a PC attached to a network.

Assigning the IP Address: DeviceInstaller on page 16.)

(See

Web Manager: Through a web browser, configure the UDS settings using the

Lantronix Web Manager. (See

Serial and Telnet Ports: Use Setup Mode, a command line interface. There are two

approaches to accessing Setup Mode: making a Telnet connection to the network port (9999) or connecting a terminal (or a PC running a terminal emulation program)

to the unit’s serial port. (See

4: Configuration Using Web Manager.)

5: Configuration via Telnet or Serial Port (Setup Mode).)

UDS2100 User Guide 11

Product Information Label

The product information label on the underside of the unit contains the following information about your specific unit:

 Bar code

 Serial number

 Product ID (name)

 Product description

 Hardware address (also referred to as the Ethernet or MAC address)

Required Information

Before configuring the UDS, have the following information available:

Hardware Address

Take note of the unit’s hardware address (also known as the Ethernet or MAC address). It is on the product label, in the format: 00-20-4a-XX-XX-XX, where the XXs are unique numbers assigned to the product

Hardware Address: 00-20-4a-_____-_____-_____

IP Address

The UDS must have a unique IP address on your network. This address references the specific unit. By default, the unit is DHCP-enabled and automatically assigned an IP address on DHCP-enabled networks. If you are assigning a static IP address, the systems administrator generally provides the IP address, subnet mask, and gateway.

Note: The factory default IP address is 0.0.0.0 to enable DHCP, BOOTP,

and AutoIP. When the units boots, it sends a DHCP broadcast to try and get an IP address. If it receives no reply from a DHCP server, the UDS tries BOOTP. If the UDS does not receive a response from BOOTP, it reverts to an AutoIP address.

You must configure the unit so it can communicate on a network with your serial device. For example, you must set the way the unit will respond to serial and network traffic, how it will handle serial packets, and when to start or close a connection.

The unit’s configuration is stored in nonvolatile memory and is retained without power. You can change the configuration at any time. The unit performs a reset after you change and store the configuration.

In this chapter, we describe how to configure the UDS2100 using Web Manager, Lantronix’s browser-based configuration tool. (For information on using Setup Mode, our command line configuration interface, see

received from the serial port. The first character of the command string must be a C (ASCII 0x43), and the last character must be either a carriage return (ASCII 0x0D) or a line feed (0x0A). No blanks or space characters may be in the command string. Between the first and last command string characters must be a full or partial destination IP address and may be a destination port number.

The IP address must be in standard decimal-dot notation and may be a partial address, representing the least significant 1, 2, or 3 bytes of the remote IP address. The period is required between each pair of IP address numbers.

If present, the port number must follow the IP address, must be presented as a decimal number in the range 1-65535, and must be preceded by a forward slash (ASCII 0x2F). The slash separates the IP address and the port number. If you omit the port number from a command string, the internally stored remote port number starts a connection.

If a partial IP address is presented in a command string, it is interpreted to be the least significant bytes of the IP address and uses the internally stored remote IP address to provide the most significant bytes of the IP address. If the IP address entered is

0.0.0.0/0, the device server enters Monitor Mode.

For example, if the remote IP address already configured in the unit is 129.1.2.3, then an example command string would be C3/7. (This would connect to 129.1.2.3 and port 7.) You may also use a different ending for the connection string. For example, C50.1/23 would connect you to 129.1.50.1 and port 23.

UDS2100 User Guide 46

7: Setup Mode: Channel Configuration

If an IP address does not follow the first command string character (which is "C"), the subsequent character string is interpreted as the host name and domain to be used in DNS lookup. This character string can include a destination port number as well. The port number can be preceded by either a forward slash (/) or a colon ( : ).

Autostart (Automatic Connection)

If you enable Autostart, the unit automatically connects to the

remote IP address and remote port specified when the firmware starts.

Hostlist If you enable this option, the device server scrolls through the

hostlist until it connects to a device listed in the hostlist table. Once it connects, the unit stops trying to connect to any others. If this connection fails, the unit continues to scroll through the table until it is able to connect to another IP in the hostlist. Hostlist supports a minimum of 1 and a maximum of 12 entries. Each entry contains the IP address and the port number.

The hostlist is disabled for Manual and Modem Modes. The unit does not accept a data connection from a remote device when the hostlist option is enabled.

UDS2100 User Guide 47

d) Datagram Type

Directed UDP When selecting this option, you are prompted for the Datagram type.

Enter 01 for directed or broadcast UDP. Datagrams of type 01 can be sent as a broadcast by enabling the Send as Broadcast option. The

default is not to broadcast.

UDS2100 User Guide 48

e) Modem Mode

In Modem (Emulation) Mode, the unit presents a modem interface to the attached serial device. It accepts AT-style modem commands and handles the modem signals correctly.

Normally, there is a modem connected to a local PC and a modem connected to a remote machine. A user must dial from the local PC to the remote machine, accumulating phone charges for each connection. Modem Mode allows you to replace modems with UDS2100s, and to use an Ethernet connection instead of a phone call. By not having to change communications applications, you avoid potentially expensive phone calls.

To select Modem Mode, set the Connect Mode to C6 (no echo), D6 (echo with full verbose), D7 (echo with numeric response), CF (modem responses only, numeric response), or CE (modem responses only, full verbose).

Note: If the unit is in Modem Mode, and the serial port is idle, the unit can still accept network TCP connections to the serial port if Connect Mode is set to C6 (no echo), D6 (echo with full verbose), D7 (echo with numeric response, CF (modem responses only, numeric response), or CE (modem responses only, full verbose).

7: Setup Mode: Channel Configuration

When the UDP option is in effect, the unit never attempts to initiate a TCP connection because it uses UDP datagrams to send and receive data.

Without Echo In Modem Mode, echo refers to the echo of all of the characters

entered in command mode; it does not mean to echo data that is transferred. Quiet Mode (without echo) refers to the modem not

sending an answer to the commands received (or displaying what was typed).

Data Echo & Modem Response

Modem Responses Only

Full Verbose: The unit echoes modem commands and responds to a command with a message string shown in the table below.

Numeric Response: The unit echoes modem commands and responds to a command with a numeric response.

A remote device, having IP address n.n.n.n, is connecting to this device.

Received commands must begin with the two-character sequence AT and be

terminated with a carriage return character.

The unit ignores any character sequence received not starting with AT, and only recognizes and processes single AT-style commands. The unit treats compound AT

commands as unrecognized commands.

If the Full Verbose option is in effect, the unit responds to an unrecognized command string that is otherwise formatted correctly (begins with AT and ends with

carriage return) with the "OK" message and takes no further action.

If the Numeric Response option is in effect, the unit responds to an unrecognized

command string that is otherwise formatted correctly with a "0" message and takes no further action.

When an active connection is in effect, the unit transfers data and does not process commands received from the serial interface.

When a connection is terminated or lost, the unit reverts to command mode.

When an active connection is in effect, the unit terminates the connection if it receives the following sequence from the attached serial device:

 No serial data is received for one second.

 The character sequence +++ is received, with no more than one second

between each two characters.

 No serial data is received for one second after the last + character. At this time,

the unit responds affirmatively per the selected echo/response mode.

 The character string ATH is received terminated with a carriage return. The

unit responds affirmatively according to the selected echo/response mode and drops the network connection. The serial interface reverts to accepting command strings.

If this sequence is not followed, the unit remains in data transfer mode.

Alternate Packing Algorithm (Pack Control)

Enable 1

Pack Control

The packing algorithms define how and when packets are sent to the network. The standard algorithm is optimized for applications in which the unit is used in a local environment, allowing for very small delays for single characters, while keeping the

UDS2100 User Guide 53

7: Setup Mode: Channel Configuration

packet count low. The alternate packing algorithm minimizes the packet count on the network and is especially useful in applications in a routed Wide Area Network (WAN). Adjusting parameters in this mode can economize the network data stream.

Pack control settings are enabled in Flush Mode. Set this value to 00 if you do not

need specific functions.

Note: All bit positions in the table that are blank represent “don’t care” bits for

Packing Interval

Packing Interval defines how long the unit should wait before sending accumulated characters. This wait period is between successive network segments containing

data. For alternate packing, the default interval is 12 ms.

Trailing Characters

In some applications, CRC, Checksum, or other trailing characters follow the end-ofsequence character; this option helps to adapt frame transmission to the frame

boundary. The default setting is 00 (none).

Send Characters

 If 2-Byte Send Character Sequence is enabled, the unit interprets the

sendchars as a 2-byte sequence; if this option is not enabled, the unit

interprets them independently. The default setting is 0 (disabled).

 If Send Immediately After Characters is not set, any characters already in

the serial buffer are included in the transmission after a "transmit" condition is found. If this option is set, the unit sends immediately after recognizing the

transmit condition (sendchar or timeout). The default setting is 0.

UDS2100 User Guide 54

Note: A transmission might occur if status information needs to be

exchanged or an acknowledgment needs to be sent.

DisConnTime (Inactivity Timeout)

Use this parameter to set an inactivity timeout. The unit drops the connection if there is no activity on the serial line before the set time expires. Enter time in the format mm:ss, where m is the number of minutes and s is the number of seconds.

DisConnTime (00:00) ?:

To disable the inactivity timeout, enter 00:00. Range is 0 (disabled) to 5999 seconds (99 minutes, 59 seconds). Default setting is 0.

Send Characters

Enter up to two characters in hexadecimal representation in sendchar.

SendChar 1 (00) ? _ SendChar 2 (00) ? _

If the unit receives a character on the serial line that matches one of these characters, it sends the character immediately, along with any awaiting characters, to the TCP connection. This action minimizes the response time for specific protocol

characters on the serial line (for example, ETX, EOT). Setting the first sendchar to 00

disables the recognition of the characters. Alternatively, the unit can interpret two characters as a sequence (see

Pack Control on page 53). The default setting is 00.

7: Setup Mode: Channel Configuration

Telnet Terminal Type

This parameter displays only if you enabled the terminal type option in Disconnect Mode. With this option enabled, you can use the terminal name for the Telnet terminal type. Enter only one name.

With terminal type option enabled, the unit also reacts to the EOR (end of record) and binary options, useful for applications like terminal emulation to IBM hosts.

Channel (Port) Password

This parameter appears only if the channel (port) password option is enabled in Disconnect Mode. With this option enabled, you can set a password on the serial port. There is no default password.

Obtaining Firmware

You can obtain the most up-to-date firmware and release notes for the unit from the Lantronix web site (www.lantronix.com

ftp.lantronix.com).

(

Reloading Firmware

There are several ways to update the unit's internal operational code (*.ROM): using DeviceInstaller (the preferred way), using TFTP, or using the serial port. You can also update the unit's internal Web interface (*.COB) using TFTP or DeviceInstaller.

Here are typical names for those files. Check the Lantronix web site for the latest

versions and release notes.

) or by using anonymous FTP

Using TFTP: Graphical User Interface

To download new firmware from a computer:

1. Use a TFTP client to send a binary file to the unit (*.ROM to upgrade the unit's internal operational code and *.COB to upgrade its internal Web interface).

Note: TFTP requires the .ROM (binary) version of the unit's internal

operational code.

2. In the TFTP server field, enter the IP address of the unit being upgraded.

3. Select Upload operation and Binary format.

4. Enter the full path of the firmware file in the Local file name field.

5. In the Remote file name field, enter the current internal operational code (U4) or WEB1 to WEB19 for the internal Web interface.

6. Click the Upload Now button to transfer the file to the unit.

Figure 9-1. TFTP Window

After the firmware has been loaded and stored, which takes approximately 8 seconds to complete, the unit performs a power reset.

Using TFTP: Command Line Interface

To download new firmware from a computer:

1. Enter the following from a TFTP command line interface:

tftp –i <ip address> put <local filename> <destination file name>

The following examples demonstrate the TFTP command sequence to download the .rom file and the .cob file:

tftp –i 192.168.1.111 put UDS2100_6102.rom U4 tftp –i 192.168.1.111 put UDS2100_webm_1403.cob WEB1

Recovering the Firmware Using the Serial Port and DeviceInstaller

If for some reason the firmware is damaged, you can recover the firmware file by using DeviceInstaller to download the *.ROM file over the serial port.

To recover firmware:

1. Connect the COM interface of your PC to serial port 1 of the unit.

2. Start DeviceInstaller. If your PC has more than one network adapter, a message

displays. Select an adapter and click OK.

3. From the Tools menu, select Advanced/Recover Firmware. The Serial Port

This chapter discusses how you can diagnose and fix errors quickly without having to contact a dealer or Lantronix. It helps to connect a terminal to the serial port while diagnosing an error to view summary messages that may display. When troubleshooting, always ensure that the physical connections (power cable, network cable, and serial cable) are secure.

Note: Some unexplained errors might be caused by duplicate IP addresses on the

network. Make sure that your unit's IP address is unique.

When troubleshooting the following problems, make sure that the UDS2100 is powered up. Confirm that you are using a good network connection.

When you issue the ARP –S command in Windows, the "ARP entry addition failed: 5" message displays.

Your currently logged-in user does not have the correct rights to use this command on this PC.

Have someone from your IT department log you in with sufficient rights.

When you attempt to assign an IP address to the unit by the ARP method, the "Press Enter to go into Setup Mode" error "(described below) message displays. Now when you Telnet to the device server, the connection fails.

When you Telnet to port 9999, the "Press Enter to go into Setup Mode" message displays. However, nothing happens when you press Enter, or your connection is closed.

When you Telnet to port 1 to assign an IP address to the device server, the Telnet window does not respond for a long time.

When you Telnet to port 1 on the device server, you are only assigning a temporary IP address. When you Telnet into port 9999 and do not press Enter quickly, the device server reboots, causing it to lose the IP address.

You did not press Enter quickly enough. You only have 5 seconds to press Enter before the connection is closed.

You may have entered the Ethernet address incorrectly with the ARP command.

The IP address you are trying to assign is not on your logical subnet.

Telnet back to Port 1. Wait for it to fail, then Telnet to port 9999 again. Make sure you press Enter quickly.

Telnet to port 9999 again, but press Enter as soon as you see the "Press Enter to go into Setup Mode" message.

Confirm that the Ethernet address that you entered with the ARP command is correct. The Ethernet address may only include numbers 0-9 and letters A-F. In Windows and usually in Unix, the segments of the Ethernet address are separated by dashes. In some forms of Unix, the Ethernet address is segmented with colons.

Confirm that your PC has an IP address and that it is in the same logical subnet that you are trying to assign to the device server.

When you try to assign an IP with DeviceInstaller, you get the following :

"No response from device!

Verify the IP, Hardware

Address and Network Class.

Please try again."

The device server may not be plugged into the network properly.

The cause is most likely one of the following:

The hardware address you specified is incorrect.

The IP address you are trying to assign is not a valid IP for your logical subnet.

You did not choose the correct subnet mask.

Make sure that the Link LED is lit. If the Link LED is not lit, then the device server is not properly plugged into the network.

Double-check the parameters that you specified.

Note: You cannot assign an IP

address to a device server through a router.

UDS2100 User Guide 69

11: Troubleshooting and Contact Information

Problem/Message Reason Solution

The device server is not communicating with the serial device to which it is attached.

The most likely reason is the wrong serial settings were chosen.

The serial settings for the serial device and the device server must match. The default serial settings for the device server are RS-232, 9600 baud, 8 character bits, no parity, 1 stop bit, no flow control.

When you try to enter the setup mode on the device server using the serial port, you get no response.

You can ping the device server, but not Telnet to the device server on port 9999.

With DeviceInstaller, you get the "Wrong Password" error when you try to upgrade the firmware.

The device server appears to be set up correctly, but you are not communicating with your device attached to the device server across the network.

The issue is most likely something covered in the previous problem, or possibly, you have Caps Lock on.

There may be an IP address conflict on your network

You are not Telneting to port 9999.

The Telnet configuration port (9999) is disabled within the device server security settings.

The file you are attempting to load is the incorrect firmware file for the UDS.

If you are sure that the serial port setting is correct, then you may not be connecting to the correct socket of the device server.

Another possibility is that the device server is not set up correctly to make a good socket connection to the network.

Double-check everything in the problem above. Confirm that Caps Lock is not on.

Turn the device server off and then issue the following commands at the DOS prompt of your computer:

ARP -D X.X.X.X (X.X.X.X is the IP of the device server).

PING X.X.X.X (X.X.X.X is the IP of the device server).

If you get a response, then there is a duplicate IP address on the network. If you do not get a response, use the serial port to verify that Telnet is not disabled.

Download the correct firmware file from the Lantronix website.

Use the Connect Mode option C0 for making a connection to the UDS from the network. Use Connect Mode option C1 or C5 for a connection to the network from the UDS.

When connecting to the Web Manager within the device server, the "No Connection With The Device Server" message displays.

Your computer is not able to connect to port 30718 (77FEh) on the device server.

Make sure that port 30718 (77FEh) is not blocked with any router that you are using on the network. Also, make sure that port 77FEh is not disabled within the Security settings of the device server.

Earlier chapters describe how to assign a static IP address using DeviceInstaller, Web Manager, and Setup Mode (through a Telnet or serial connection). This section covers other methods for assigning an IP address over the network.

DHCP

The unit ships with a default IP address of 0.0.0.0, which automatically enables DHCP. If a DHCP server exists on the network, it provides the unit with an IP address, gateway address, and subnet mask when the unit boots up.

You can use the DeviceInstaller software to search the network for the DHCPassigned IP address and add it to the list of devices retrieved.

Note: This DHCP address does not appear in the unit’s Setup Mode or in

Web Manager. You can determine your unit’s DHCP- assigned IP address in Monitor Mode. When you enter Monitor Mode from the serial port with network connection enabled and issue the NC (Network Communication) command, you see the unit’s IP configuration.

AutoIP

The unit ships with a default IP address of 0.0.0.0, which automatically enables Auto IP within the unit. AutoIP is an alternative to DHCP that allows hosts to obtain an IP address automatically in smaller networks that may not have a DHCP server. A range of IP addresses (from 169.254.0.1 to 169.254.255.1) has been explicitly reserved for AutoIP-enabled devices. Do not use this range of Auto IP addresses over the Internet.

 If your unit cannot find a DHCP server, and you have not manually assigned an

IP address to it, the unit automatically selects an address from the AutoIP reserved range. Then, your unit sends out a (ARP) request to other nodes on the same network to see whether the selected address is being used.

 If the selected address is not in use, then the unit uses it for local subnet

communication.

 If another device is using the selected IP address, the unit selects another

address from the AutoIP range and reboots. After reboot, the unit sends out another ARP request to see if the selected address is in use, and so on.

AutoIP does not replace DHCP. The unit continues to look for a DHCP server on the network. If it finds a DHCP server, the unit switches to the DHCP server-provided address and reboots.

Note: If a DHCP server is found, but it denies the request for an IP address,

the unit does not attach to the network, but waits and retries.

AutoIP can be disabled by setting the unit’s IP address to 0.0.1.0. This setting enables DHCP but disables AutoIP.

UDS2100 User Guide 78

BOOTP

Similar to DHCP, but for smaller networks. Automatically assigns the IP address for a

specific duration of time.

ARP and Telnet

If the unit has no IP address, you can use Address Resolution Protocol (ARP) method from UNIX and Windows-based systems to assign a temporary IP address.

To assign a temporary IP address:

1. On a UNIX or Windows-based host, create an entry in the host's ARP table

using the intended IP address and the hardware address of the unit (on the product label on the bottom of the unit).

arp -s 191.12.3.77 00-20-4a-xx-xx-xx (Windows)

Note: For the ARP command to work on Windows 95, the ARP table

on the PC must have at least one IP address defined other than its own.

B: Alternative Ways to Assign an IP Address

arp -s 191.12.3.77 00:20:4a:xx:xx:xx (Unix)

2. If you are using Windows 95, type ARP -A at the DOS command prompt to

verify that there is at least one entry in the ARP table. If the local machine is the only entry, ping another IP address on your network to build a new entry in the ARP table; the IP address must be a host other than the machine on which you are working. Once there is at least one additional entry in the ARP table, use the following command to ARP an IP address to the unit:

arp -s 191.12.3.77 00-20-4a-xx-xx-xx

3. Open a Telnet connection to port 1. The connection fails quickly, but the unit

temporarily changes its IP address to the one designated in this step.

telnet 191.12.3.77 1

4. Open a Telnet connection to port 9999, and press Enter within five seconds

to go into Setup Mode. If you wait longer than five seconds, the unit reboots.

telnet 191.12.3.77 9999

Note: The IP address you just set is temporary and reverts to the default

value when the unit’s power is reset, unless you configure the unit with a static IP address and store the changes permanently.

Hexadecimal digits have values ranging from 0 to F, which are represented as 0-9, A (for 10), B (for 11), etc. To convert a binary value (for example, 0100 1100) to a hexadecimal representation, the upper and lower four bits are treated separately, resulting in a two-digit hexadecimal number (in this case, 4C). Use the following table to convert values from binary to hexadecimal.

Decimal Binary Hex

0 0000 0

1 0001 1

2 0010 2

3 0011 3

4 0100 4

5 0101 5

6 0110 6

7 0111 7

8 1000 8

9 1001 9

10 1010 A

11 1011 B

12 1100 C

13 1101 D

14 1110 E

15 1111 F
