Additional Documentation

The following information is available on the product CD or the Lantronix Web
site:www.lantronix.com
DeviceInstaller User Guide Provides instructions for using the Windows-based utility to
configure the UDS and other Lantronix device servers. (CD and web site)

22:: IInnttrroodduuccttiioonn
The UDS10 and UDS100 are single-port device servers that provide a quick, simple, and cost-effective way to bring the advantages of data accessibility and remote management to devices not currently connected to a network.
The main difference between the two models is that the UDS100 provides both half and full duplex 10/100 Ethernet data transfer, whereas the UDS10 provides only half duplex 10Base-T Ethernet. The technical specifications of the two products differ slightly as well. Unless otherwise noted, we refer to both products as the UDS.

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.
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.

Introduction UDS10/UDS100 User Guide

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 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, leveraging network connections and bandwidth to eliminate dedicated modems and phone lines.
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.
(See DeviceInstaller on page 16.) Web Manager: Through a web interface configures the UDS settings using the
Lantronix Web Manager. (See 4: Configuring the UDS Using Web Manager.) Serial and Telnet Ports: 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 5: Configuring the UDS Using Telnet or the Serial Port.)

UDS10/UDS100 User Guide Getting Started

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 (see Product Information Label on
page13).
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 device 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.
IP Address: _______ _______ _______ _______
Subnet Mask: ___
____ _______ _______ _______
Gateway: _______ _______ _______ _______
You have several options for assigning an IP to your unit. This chapter provides
information about using the DeviceInstaller (graphical user interface) and serial port
login (command line interface) methods.
Note: For information about other methods of assigning the IP address,
such as DHCP, AutoIP, ARP, and Telnet, see A: Alternative Ways to Assign
an IP Address.

Setting the Telnet configuration password prevents unauthorized access to Setup Mode using a Telnet connection to port 9999 or using Web pages. The password is limited to 4 characters. An enhanced password setting of 16 characters is available under Security Settings.
Note: No password is required to access the Setup Mode using a serial
connection.

DHCP Naming

A DHCP name is a unique identifier used for managing multiple DHCP hosts on a network. Your unit ships with a default DHCP name of Cxxxxxx, where xxxxxx is the last six digits of the Mac address.
You can change the DHCP name (up to eight characters) when configuring the server in Setup Mode. Change the DHCP name to LTXdd, where 0.0.0.dd is the IP address assigned (dd should be a number between 1 and 99). For example, if the IP address is set to 0.0.0.5, the resulting DHCP name is LTX05.
25
Configuring the UDS Using Telnet or the Serial Port UDS10/UDS100 User Guide
If you give the unit an IP of 0.0.0.0, you then have the option to assign an 8-character DHCP name.

Note: Some fields require entries in hexadecimal notation. A simple way to
convert a binary number to a hexadecimal is to use a scientific calculator, such as the one available in Windows. For more information, see B: Binary to
Hexadecimal Conversions.
Select 1 from the Change Setup menu to define how the serial port responds to
network and serial communications. Current values display in parentheses. The following sections describe the configurable settings within the Server configuration menu.
Figure 5-5. Channel 1 Configuration

Baudrate

The unit and attached serial device, such as a modem, must agree on a speed or baud rate to use for the serial connection. Valid baud rates are 300, 600, 1200, 2400, 4800, 9600 (default), 19200, 38400, 57600, and 115200 bits per second.

I/F (Interface) Mode

The Interface (I/F) Mode is a bit-coded byte that you enter in hexadecimal notation.
Note: To look up hex values, see B: Binary to Hexadecimal.

Port Number

Every TCP connection and every UDP datagram has a destination IP address and a port number. A port number is similar to an extension on a PBX system. For example, a Telnet application commonly uses port number 23. Port number 9999 is reserved for access to the unit's Setup Mode.
The Port Number setting represents the source port number in TCP connections. It is the number that identifies the channel for remote initiating connections. For example, to send data to channel 1, send TCP/UDP packets to this assigned port number.
The default setting for port 1 is 10001. The range is 1-65535, except for the following reserved port numbers:
27

Table 4-5. Reserved Port Numbers
Port Numbers Reserved for

9999 Telnet setup
30718 Reserved (77FEh)
Warning: We recommend that you not use the reserved port numbers
for this setting as incorrect operation may result.
Use port 0 for the outgoing local port to change with each connection. The port range is 50,000 to 59,999. Each subsequent connection increments the number by 1. (When the port number reaches 59999, it wraps around to 50000.)
Only use the automatic port increment feature to initiate a connection using TCP. Set the port to a non-zero value when the unit is in a passive mode or when you are using UDP instead of TCP.

Connect Mode

Connect Mode defines how the unit makes a connection, and how it reacts to incoming connections over the network. Enter Connect Mode options in hexadecimal notation.

UDS10/UDS100 User Guide Configuring the UDS Using Telnet or the Serial Port

Manual Connection

The UDS attempts to connect when directed by a command string 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 spaces may be in the command string. Between the first and last command string characters must be a full or partial destination IP address and can include a destination port number.
The IP address must be in standard dot-decimal notation and may be a partial address, representing the least significant 1, 2, or 3 bytes of the remote IP address. A period is required between each pair of IP address numbers.
If present, the port number must follow the IP address, must be 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 becomes the destination port number when the connection attempt is made.
If the command string includes a partial IP address, the UDS interprets it 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.

Autostart (Automatic Connection): If you enable autostart, the unit automatically
connects to the remote IP address and remote port specified.
Datagram Type: When selecting this option, you will be prompted for the datagram type. Enter 01 for directed or broadcast UDP.
Hostlist: If you enable this option, the Lantronix unit 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 connects to another IP in the hostlist.
29
Configuring the UDS Using Telnet or the Serial Port UDS10/UDS100 User Guide
Figure 5-6. Hostlist Option
To use the hostlist option, follow these steps:
1. To enable the hostlist, enter a Connect Mode of 0x20 (2X). The menu shows you
a list of current entries already defined in the product.
2. To delete, modify, or add an entry, select Yes. If you enter an IP address of
0.0.0.0, that entry and all others after it are deleted.
3. After completing the hostlist, repeat the previous step if necessary to edit the hostlist again.
4. For Retrycounter, enter the number of times the Lantronix unit should try to
make a good network connection to a hostlist entry that it has successfully ARPed.
5. For Retrytimeout, enter the number of seconds the unit should wait before
failing an attempted connection.
Modem (Emulation) Mode: In Modem 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,
30
UDS10/UDS100 User Guide Configuring the UDS Using Telnet or the Serial Port
accumulating phone charges for each connection. Modem Mode allows you to replace modems with UDS units, 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), or D7 (echo with 1-character response).
Note: If the unit is in Modem Mode and the serial port is idle, the unit still
accepts network TCP connections to the serial port if Connect Mode is set to C6 (no echo), D6 (echo with full verbose), or D7 (echo with 1-character response).
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 (no echo) refers to the modem not sending an answer to the commands received (or displaying what was typed).
Full Verbose: The unit echoes modem commands and responds to a
command with a message string.
1-Character Response: The unit echoes modem commands and responds
to a command with a single character response.
To disconnect a connection using Modem Mode commands:
1. Ensure the following:
There must be a 1-second guardtime (no data traffic) before sending +++.
There must not be a break longer than 1 second between +s.
There must be another 1-second guardtime after the last + is sent.
2. When the unit acknowledges with an OK to indicate that it is in command mode,
enter ATH and press Enter. The command is echoed if echo is enabled. ATH is acknowledged by another OK.

Remote IP Address

This is the destination IP address used with an outgoing connection.

Remote Port

The remote TCP port number must be set for the unit to make outgoing connections. This parameter defines the port number on the target host to which a connection is attempted.
Note: To connect an ASCII terminal to a host using the unit for login
purposes, use the remote port number 23 (Internet standard port number for Telnet services).

Alternate Packing Algorithm (Pack Control)
Enable 1
33
Configuring the UDS Using Telnet or the Serial Port UDS10/UDS100 User Guide

Pack Control

Two firmware-selectable packing algorithms define how and when the unit sends packets 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 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 settings in this mode can economize the network data stream.
Pack control settings are enabled in Flush Mode. Set Pack Control to 00 if specific
functions are not needed.
Note: To look up hex values, see B: Binary to Hexadecimal.

Trailing Characters
None 0 0 One 0 1 Two 1 0
Send Characters
2-Byte Send Character Sequence 1 Send Immediately After Send chars 1
Idle Time: Idle time to "Force transmit" defines how long the unit waits before
sending accumulated characters. This wait period is between characters. If there is an idle period between characters equal to the force transmit set, the UDS packages the serial data currently in the buffer and sends it to the network.
Trailing Characters: In some applications, CRC, Checksum, or other trailing
characters follow the end-of-sequence character. This option helps to adapt frame transmission to the frame boundary.
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.
If Send Immediately After Send Characters is not set, any characters already
in the serial buffer are included in the transmission after the unit finds a "transmit" condition. With this option, the unit sends immediately after recognizing the transmit condition (sendchar or timeout).
Note: A transmission might occur if status information needs to be
exchanged or an acknowledgment needs to be sent.
34
UDS10/UDS100 User Guide Configuring the UDS Using Telnet or the Serial Port

Disconnect Time (Inactivity Timeout)

Use Disconnect Time 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 following format: mm:ss, where m is the number of minutes and s is the number of
seconds. To disable the inactivity timeout, enter 00:00. Range is 0 (disabled) to 5999
seconds (99 minutes, 59 seconds). The default is 0.

Send Characters

Enter up to two characters in hexadecimal representation for the SendChar settings. 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 34).

Telnet Terminal Type

This parameter displays only if the terminal type option is enabled in Disconnect Mode. If this option is enabled, use the terminal name for the Telnet terminal type. Enter only one name.
If the terminal type option is enabled, the unit also reacts to the EOR (end of record) and binary options that can be used for applications like terminal emulation to IBM hosts.

Channel (Port) Password

This parameter displays only if the channel (port) password option is enabled in Disconnect Mode. If the option is enabled, set a password on the serial port.

Expert Settings

Note: Change these settings using Telnet or serial connections only, not
Web Manager.
Caution: Only an expert should change these parameters. These
changes have serious consequences.

Configuring the UDS Using Telnet or the Serial Port UDS10/UDS100 User Guide

TCP Keepalive time in s

This option defines how many seconds the unit waits during a silent connection before checking to see whether the currently connected network device is still on the network. If the unit does not receive a response, it drops that connection.

ARP Cache timeout in s

When the unit communicates with another device on the network, it adds an entry into its ARP table. The ARP Cache timeout option defines the number of seconds (1-600) the unit waits before timing out an entry in this table.

Security Settings

Change these settings using Telnet or serial connections only, not Web Manager.
Note: We recommend that you set security over the dedicated network or
over the serial setup. If you set security over the network (Telnet 9999), someone else could capture these settings.
Caution: Disabling both Telnet Setup and Port 77FE prevents users
from accessing the Setup Mode from the network.

Disable SNMP

Figure 5-8. Security Settings
This setting disables the SNMP protocol on the unit to prevent SNMP management software from communicating with the UDS.

UDS10/UDS100 User Guide Configuring the UDS Using Telnet or the Serial Port

SNMP Community Name

This option changes the SNMP community name on the unit. This allows for ease of management, and possibly some security. If someone tries to violate security but does not know what community to connect to, that person is unable to obtain the
SNMP community information from the unit. The default is public.

Disable Telnet Setup

Caution: Disabling both Telnet Setup and Port 77FE prevents users
from accessing Setup Mode from the network.
This setting defaults to the N (No) option. The Y (Yes) option disables access to Setup Mode by Telnet (port 9999). It only allows access locally using Web Manager and the serial port of the unit.

Disable TFTP Firmware Upgrade

This setting defaults to the N (No) option. The Y (Yes) option disables TFTP for network firmware upgrades. With this option, firmware upgrades can be performed only by using a *.hex file over the serial port of the unit.

Disable Port 77FE (Hex)

Caution: Disabling both Telnet Setup and Port 77FE prevents users
from accessing the Setup Mode from the network.
Port 77FE is used by DeviceInstaller, Web Manager, and custom programs to configure the unit remotely. If required, disable this capability for security purposes.
The default setting is the N (No) option, which enables remote configuration. As a result, configure the unit by using DeviceInstaller, Web Manager, Telnet, or serial configuration.
The Y (Yes) option disables remote configuration and web sites.
Note: the Y (Yes) option disables many of the GUI tools for configuring the unit,
including Web Manager.

Disable Web Setup

The Y (Yes) option disables the use of Web Manager. It disables browser-initiated sessions to port 80 on the UDS and configuration using HTTP. Port 80 is closed.

Disable ECHO Ports

Port 7 accepts Telnet and UDP connections. Whatever data is sent to this port is echoed back to the sender. This setting disables the use of the echo server that is built into the unit.

Enable Enhanced Password

This setting defaults to the N (No) option, which permits a 4-character password that protects the Setup Mode using Telnet and Web Manager. The Y (Yes) option allows an extended security password of 16-characters for protecting Telnet access.

This chapter explains how to obtain and update the unit’s firmware.

Obtaining Firmware

Obtain the most up-to-date firmware and release notes for the unit from the Lantronix Web site (http://www.lantronix.com/) or by using anonymous FTP (ftp://ftp.lantronix.com/).

Reloading Firmware

There are several ways to update the unit's internal operational code. Use DeviceInstaller (the preferred way), TFTP, another unit, or the serial port. Another
option is to use the unit's internal web interface (CBXW*.COB) using TFTP or
DeviceInstaller.
Following are typical names for the files. Check the Lantronix Web site for the latest versions and release notes.
UDS10
LTX*.ROM (Network)
LTX*.HEX (Serial)
UDS100
DLX*.ROM (Network)
DLX*.3HEX (Serial)

Using DeviceInstaller

1. Download the updated firmware files from http://www.lantronix.com/ or
ftp://ftp.lantronix.com/ and store them in a subfolder on your computer.
2. Click the Start button on the Task Bar and select Programs Æ Lantronix Æ
DeviceInstaller Æ DeviceInstaller. The DeviceInstaller window displays.
3. Click the Search the network for devices icon. The Search Network window

the Web Manager files (.COB).
7. Click Next again. The status of the upgrade shows in the window.
8. After the upgrade completes, click Close.

Using TFTP

If you are running Windows NT or higher, you can simply enter the following command at the command prompt:
TFTP –i IP address of UDS PUT source file name destination file name
Note: It is easiest to issue the command from the same directory as the one
where the firmware files are.
To download new firmware using a TFTP client:
1. Use a TFTP client to send a binary file (LTX*.ROM for UDS10, DLX*.ROM for
UDS100) to the unit to upgrade the unit's internal operational code, and
CBXW*.cob to upgrade its internal web interface).
Note: TFTP requires the .ROM (binary) version of the unit's internal
operational code.
2. Make sure the Put and Binary options at the top of the window are selected.
3. Enter the full path of the firmware file in the Source File field.
4. In the Destination File field, type of the following:
3L for the UDS10 or 3D for the UDS100 to load the internal operational code WEB6 for the internal web interface.
5. In the Remote Host field, enter the IP address of the unit being upgraded.
6. Click the Put button to transfer the file to the unit.

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 so you can 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.

LEDs

The UDS products contain the following LEDs, which help you diagnose problems.
10 Mbps Link/Activity (green)
100 Mbps Link/Activity (green)
Collisions
Diagnostics (red)
Status (yellow)
Simultaneously lit red and green LEDs mean something is wrong. If the red LED is lit or blinking, count the number of times the green LED blinks between its pauses. The following table explains the LED functions:

Problems and Error Messages

Notes:
When troubleshooting the following problems, make sure that the UDS is
powered up and the Link LED is lit solid green. If the Link LED is not lit, then the physical network connection is bad. Confirm that you are using a good network connection.
We recommend that you use a serial connection so you can view any
diagnostic information sent out the serial port.

Problem/Message Reason Solution
When you Telnet to port 1 to assign an IP address to the UDS, the Telnet window does not respond for a long time.
When you try to assign an IP with DeviceInstaller, you get the following message:
No device was found at this hardware address.
You may have entered the hardware address incorrectly with the ARP command.
The IP address you are trying to assign is not on your logical subnet.
The UDS 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 device is not physically connected to the network.
Confirm that the hardware address that you entered with the ARP command is correct. The hardware address may only include numbers 0-9 and letters A-F. In Windows and usually in Unix, the segments of the address are separated by dashes. In some forms of Unix, the 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 UDS.
Make sure that the Link LED is lit. If the Link LED is not lit, then the UDS is not properly plugged into the network.
Double-check the settings that you specified.
Note: You cannot assign
an IP address to a UDS through a router.
No LEDs are lit. The unit or its power supply is
damaged, or the unit is not plugged into power properly.
The UDS will not power up properly, and the LEDs are flashing.
Various Consult the LEDs section above or

Troubleshooting and Contact Information UDS10/UDS100 User Guide
Problem/Message Reason Solution
The UDS is not communicating with the serial device attached to the UDS.
When you try to enter Setup Mode on the UDS using the serial cable, you get no response.
You can ping the UDS, but not Telnet to the UDS on port 9999.
The most likely reason is the wrong serial cable or serial settings were chosen.
The issue is 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 UDS security settings.
The unit may have the correct IP address, but an incorrect gateway address.
Make sure that you are using the correct serial cable. The UDS serial port is just like a modem serial port (DCE). The serial settings for the serial device and the UDS must match.
The default serial settings for the UDS are RS232, 9600 baud, 8 character bits, no parity, 1 stop bit, no flow control.
Double-check everything in the
problem above. Confirm that Caps Lock is not on.
Turn the UDS 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 UDS)
PING X.X.X.X (X.X.X.X is the IP of
the UDS).
If you get a response, then there is a duplicate IP address on the network (the LEDs on the UDS should flash a sequence that tells you this). If you do not get a response, use the serial port to verify that Telnet is not disabled.
With DeviceInstaller, you get the
Wrong Password error when you try
to upgrade the firmware.
The file you are attempting to load is the incorrect firmware file for the UDS.
48
Download the correct firmware file from the Lantronix website.
UDS10/UDS100 User Guide Troubleshooting and Contac t Information
Problem/Message Reason Solution
You are using the correct serial cable, and the UDS is set up correctly, but you are not communicating with your device attached to the UDS across the network.
When connecting to Web Manager
within the UDS, the message No Connection With The UDS displays.
If you are sure that the serial cable is correct, then you may not be connecting to the correct socket of the UDS.
Another possibility is that the UDS is not set up correctly to make a good socket connection to the network.
Your computer is not able to connect to port 30718 (77FEh) on the UDS.
You can check to see whether there is a socket connection to or from the UDS by looking at the Status LED.
If the Status LED is blinking consistently, then there is a good socket connection.
If the Status LED is solid green, then the socket connection does not exist.
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. See the full list of Connect
Mode hexadecimals in B: Binary to
Hexadecimal.
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 UDS.

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 (see Entering Monitor Mode Using the Serial
Port on page 43) 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 automatically obtain an IP address 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.
57
Alternative Ways to Assign an IP Address UDS10/UDS100 User Guide

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
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.
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.

Many of the unit’s configuration procedures require you to assemble a series of options (represented as bits) into a complete command (represented as a byte). The resulting binary value must be converted to a hexadecimal representation.
Use this chapter to learn how to convert binary values to hexadecimals or to look up values in the tables of configuration options in hexadecimal notation. The tables include:
Connect Mode Options
Disconnect Mode Options
Flush Mode (Buffer Flushing) Options
Interface Mode Options
Pack Control Options

Converting Binary to Hexadecimal

Following are two simple ways to convert binary numbers to hexadecimals.

Conversion Table

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
59

Scientific Calculator

Another simple way to convert binary to hexadecimals is to use a scientific calculator, such as the one available on Windows’ operating systems. For example:
1. On the Windows’ Start menu, click ProgramsÆAccessoriesÆCalculator.
2. On the View menu, select Scientific. The scientific calculator displays.
3. Click Bin (Binary), and type the number you want to convert.
4. Click Hex. The hexadecimal value displays.
