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

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 UDS200 encapsulates serial data into packets and transports them over Ethernet. Using two UDS200 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 UDS200 User Guide

Figure 2-1. Application Examples

Note: For step-by-step instructions on configuring the UDS for serial

tunneling or for use with the Com Port Redirector, access the UDS Configuration Tutorials using Web Manager. (See Accessing Web Manager.)

Protocol Support

The UDS200 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.

Other protocols supported are:

 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 maintaining a point-to-point connection.

Introduction UDS200 User Guide

Additional Features

Modem Emulation: In modem emulation mode, the UDS200 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 UDS200 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 UDS200 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 UDS200 and assigning IP addresses and other configurable settings:

DeviceInstaller: Configure the IP address and other network settings on the UDS200 using a Graphical User Interface (GUI) on a PC attached to a network. See DeviceInstaller on page 14.)

Web Manager: Through a web interface, configure the UDS200 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.)

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 Ethernet or MAC address)

The first three bytes of the hardware address are fixed and read 00-20-4A, identifying the unit as a Lantronix product. The fourth, fifth, and sixth bytes are unique numbers assigned to each unit.

Required Information

Hardware Address

Take note of the unit’s hardware address (also known as the MAC or Ethernet 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 page

11).

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 more information other methods of assigning IP addresses, such

as DHCP, AutoIP, ARP and Telnet, see A: Alternative Ways to Assign an IP

Address.

Configuring the UDS Using Telnet or the Serial Port UDS200 User Guide

Set Gateway IP Address

The gateway address, or router, allows communication to other LAN segments. The gateway address should be the IP address of the router connected to the same LAN segment as the unit. The gateway address must be within the local network.

Netmask

A netmask defines the number of bits taken from the IP address for the host section. The host section is the part of the IP address that is specific to the UDS.

Note: Class A: 24 bits; Class B: 16 bits; Class C: 8 bits.

The unit prompts for the number of host bits to enter, then calculates the netmask, which appears in standard decimal-dot notation when the saved parameters display (for example, 255.255.255.0).

Change Telnet configuration password

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 for Telnet access only.

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

Configuring the UDS Using Telnet or the Serial Port UDS200 User Guide

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.

If you give the unit an IP of 0.0.0.0, you then have the option to assign an 8-character DHCP name.

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

The Port Number setting represents the source port number in TCP connections. It is the number that identifies the channel for remote initiating connections. To send data to channel 1, send TCP/UDP packets to this port number.

The default settings are 10001 for port 1 and 10002 for port 2. The range is 1-65535, except for the following reserved port numbers:

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.

Note: To look up hex values, see B: Binary to Hexadecimal.

Configuring the UDS Using Telnet or the Serial Port UDS200 User Guide

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 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 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, be a decimal number in the range 1-65535, and 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 command string contains a partial IP address, the UDS interprets the command string as 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 you select this option, the unit prompts 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. Only Channel 1 supports the hostlist option.

Configuring the UDS Using Telnet or the Serial Port UDS200 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.

Configuring the UDS Using Telnet or the Serial Port UDS200 User Guide

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, 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.

n=0 disables character echo and responses.

n=1 enables character echo and responses.

Enables 1-character response or full verbose:

n=0 enables 1-character response.

n=1 enables full verbose.

Note: The unit only recognizes these AT commands as single commands

like ATE0 or ATV. It does not recognize; compound commands such as ATE0V1. All other AT commands with Modem Mode set to full verbose acknowledge with an OK, but the unit takes no action.

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).

Disconnect Mode

This option determines the conditions under which the unit causes a network connection to terminate. In DisConnMode, DTR drop either drops the connection or is ignored.

Note: To look up hex values, see B: Binary to Hexadecimal.

1. The UDS sends the "Terminal Type" upon an outgoing connection.

2. A password is required for a connection to the serial port from the network.

3. The TCP connection closes even if the remote site does not acknowledge the disconnection.

4. When there is a network connection to or from the serial port, the state LED turns off instead of blinking.

5. When Ctrl D or Hex 04 is detected, the connection is dropped. Both Telnet mode and Disconnect with EOT must be enabled for Disconnect with EOT to function properly. Ctrl D is only detected going from the serial port to the network.

Flush Mode

Flush Mode (buffer flushing) controls line handling and network buffers with connection startup and disconnect. You can select between two different packing algorithms.

Note: To look up hex values, see B: Binary to Hexadecimal.

Available Flush Mode options are:

Table 5-9. Flush Mode Options

Configuring the UDS Using Telnet or the Serial Port UDS200 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.

Table 5-10. Pack Control Options

Option Bit 7 6 5 4 3 2 1 0

Idle Time Force transmit: 12ms 0 0 Force transmit: 52ms 0 1 Force transmit: 250ms 1 0 Force transmit: 5sec 1 1 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.

Configuring the UDS Using Telnet or the Serial Port UDS200 User Guide

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 32).

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 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.

Figure 5-7. Expert Settings Options

Configuring the UDS Using Telnet or the Serial Port UDS200 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.

Figure 5-8. Security Settings

Disable SNMP

This setting disables the SNMP protocol on the unit to prevent SNMP management software from communicating with the UDS.

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

Configuring the UDS Using Telnet or the Serial Port UDS200 User Guide

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.

DeviceInstaller, Web Manager, and custom programs use Port 77FE 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 Manager.

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 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.

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.

Table 8-2. Problems and Error Messages

Problem/Message Reason Solution

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

When you attempted to assign an IP address to the UDS using the ARP method, the Press Enter to go into Setup Mode error (described below) displayed. Now when you Telnet to the UDS, the connection fails.

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

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

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

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

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

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

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

Troubleshooting and Technical Support UDS200 User Guide

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 Ethernet 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 Ethernet address 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, use dashes to separate the segments of the Ethernet address. In some forms of Unix, use colons to separate the segments of the Ethernet address.

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 does not power up properly, and the LEDs are flashing.

Various Consult the LEDs section above or

Try plugging the UDS into another outlet. If this does not fix the problem, contact your dealer or Lantronix Technical Support for a replacement.

the Quick Start for the LED flashing sequence patterns. Call Lantronix Technical Support if the blinking pattern indicates a critical error.

Troubleshooting and Technical Support UDS200 User Guide

Problem/Message Reason Solution

The UDS is not communicating with tan attached serial device.

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 Tenting 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.

Download the correct firmware file from the Lantronix website.

Troubleshooting and Technical Support UDS200 User Guide

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 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 the unit finds a DHCP server, but the server denies the request for

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

Alternative Ways to Assign an IP Address UDS200 User Guide

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

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 to convert binary values to hexadecimals or to look up hexadecimal values in the tables of configuration options. The tables include:

Converting Binary to Hexadecimal

Following are two simple ways to convert binary numbers to hexadecimal notation.

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, treat the upper and lower four bits separately to produce 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

Binary to Hexadecimal Conversions UDS200 User Guide

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.
