Addresses and Port Number

Ethernet (MAC) Address

The Ethernet address is also referred to as the hardware address or the MAC address. The first three bytes of the Ethernet 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.

Figure 2-1. Sample Ethernet Address

00-20-4A-14-01-18 or 00:20:4A:14:01:18

Internet Protocol (IP) Address

Every device connected to an IP network must have a unique IP address. This address is used to reference the specific unit.

Port Number

Every TCP connection and every UDP datagram is defined by a destination IP address and a port number. For example, a Telnet application commonly uses port number 23. A port number is similar to an extension on a PBX system.

The unit's serial channel (port) can be associated with a specific TCP/UDP port number. Port number 9999 is reserved for access to the unit's Setup (configuration) Mode window.

SDS2100 User Guide 2: Getting Started

Physically Connecting the Unit

1. Connect a serial device to your unit. See the Introduction for more information about what kinds of device attachments the unit supports.

2. Connect an Ethernet cable to the 10/100 port.

3. Supply power to your unit using the power supply that was included in the packaging.

Note: The required input voltage is 9-30 VDC or 9-24 VAC

(2 W maximum).

4. Supply power to the serial device.

SDS2100 User Guide 2: Getting Started

Methods of Assigning the IP Address

The unit's IP address must be configured before a network connection is available. You have the following options for assigning an IP to your unit:

Table 2-1. Methods of Assigning IP Addresses

Method Description

DHCP A DHCP server automatically assigns the IP address and network settings. DeviceInstaller You manually assign the IP address using a graphical user interface (GUI).

You must use a PC and the unit must be attached to the local network.

ARP and Telnet You manually assign the IP address and other network settings at a

command prompt using a UNIX or Windows-based system. Only one person at a time can be logged into the configuration port (port 9999). This eliminates the possibility of several people simultaneously attempting to configure the unit.

AutoIP This automatic method is appropriate when you have a small group of hosts

rather than a large network. This method allows the hosts to negotiate with each other and assign addresses, in effect creating a small network.

Serial Port Login You initially configure the unit through a serial connection.

These methods are described in the remaining sections of this chapter.

DHCP

Note: In most installations, a fixed IP address is desirable. The systems

administrator generally provides the IP address. Obtain the following information before starting to set up your unit:

IP Address ___ ___ ___ ___ Subnet Mask: ___ ___ ___ ___ Gateway: ___ ___ ___ ___

The unit ships with a default IP address of 0.0.0.0, which automatically enables DHCP.

Provided a DHCP server exists on the network, it will provide the unit with an IP address, gateway address, and subnet mask when the unit boots up. The SDS2100 has acquired an IP address if the red LED stops flashing and the green Status LED is on continuously. (If no DHCP server exists, the unit responds with a diagnostic error: the red Diagnostic LED blinks continuously, and the green Status LED blinks five times. This blinking only continues for about 15 seconds.)

You can use the DeviceInstaller software to search the network for the IP your unit has been assigned by the DHCP server and add it to the managed list. See Add the

Unit to the Manage List later in this chapter.

Note: This DHCP address will not appear in the unit’s standard configuration

screens. You can, however, 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 Monitor Mode in the Troubleshooting chapter) and issue the NC (Network Communication) command, you will see the unit’s IP configuration.

SDS2100 User Guide 2: Getting Started

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. The range of Auto IP addresses is not to be used 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 itself. After reboot, the unit sends out another ARP request to see if the selected address is in use, and so on.

AutoIP is not intended to replace DHCP. The unit will continue to look for a DHCP server on the network. If a DHCP server is found, the unit will switch to the DHCP server-provided address and reboot.

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.

DeviceInstaller

You can manually assign the IP address using the DeviceInstaller, which is on the product CD.

Install the DeviceInstaller

1. Insert the product CD into your CD-ROM drive. The Lantronix SDS2100 DeviceServer window displays.

2. If the CD does not launch automatically:

3. Click the Start button on the Task Bar and select Run.

Now add the unit to the list of similar Lantronix devices on the network so that you can manage and configure it. To perform this step, click the Search icon:

The device should be located by DeviceInstaller and added into the Device List. Now you can manage (configure) the unit so that it works with the serial device on the network.

Opening a Configuration Window

Once the device is added into the list, use the Configure, Upgrade, Telnet, and Web icons to manage the device.

Figure 2-8. Device Management Window

1. Do one of the following:

Note: To assign Expert settings and Security settings, you must use the

Setup Mode window in a Telnet session.

 To configure the unit via a Web browser, click the Web icon. The Lantronix

WEB-Manager window displays in your browser.

 To configure the unit via a Telnet session, click the Telnet icon. The Setup

Mode window displays.

2. Continue with the appropriate configuration procedure described in the next

chapter.

Note: The Configure icon on the Device Management window allows

you to save a configuration locally on your computer as a file. It is helpful to save the file, in case, for example, someone changes the configuration of the unit incorrectly. The Configure icon sends a saved file to the unit.

SDS2100 User Guide 2: Getting Started

ARP and Telnet

The unit’s IP address must be configured before a network connection is available. If the unit has no IP address, you can use the Address Resolution Protocol (ARP) method from UNIX and Windows-based systems to assign a temporary IP address. If you want to initially configure the unit through the network, follow these steps:

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, which is found on the product label on the bottom of the unit.

Figure 2-9. ARP on UNIX

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:

Figure 2-10. ARP on Windows

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

3. Open a Telnet connection to port 1. The connection will fail quickly, but the unit will temporarily change its IP address to the one designated in this step.

Figure 2-11. Telnet to Port 1

telnet 191.12.3.77 1

4. Finally, open a Telnet connection to port 9999, and press Enter within three seconds to go into Setup Mode. If you wait longer than three seconds, the unit

will reboot.

Figure 2-12. Telnet to Port 9999

telnet 191.12.3.77 9999

Note: You will need to repeat the previous steps to temporarily assign

the IP address.

5. Set all required parameters

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

value when the unit 's power is reset unless you log into the unit and store the changes permanently. Refer to the chapter on configuration for instructions on permanently configuring the IP address.

SDS2100 User Guide 2: Getting Started

Serial Port Login

If you want to initially configure the unit through a serial connection, follow these steps:

1. Connect a console terminal or PC running a terminal emulation program to the

unit’s Channel 1 serial port. The default serial port settings are 9600 baud, 8 bits, no parity, 1 stop bit, no flow control.

2. To enter Setup Mode, cycle the unit's power (power off and back on). After

power-up, the self-test begins and the red Diagnostic LED starts blinking. You have one second to enter three lowercase x characters.

Note: The easiest way to enter Setup Mode is to hold down the x key at

the terminal (or emulation) while powering up the unit.

3. Select 0 (Server Configuration) and follow the prompts until you get to IP

address.

4. Enter the new IP address, Subnet Mask, and Gateway (if applicable).

5. Select 9 to save the configuration and exit Setup Mode. The unit performs a

power reset.

33:: CCoonnffiigguurriinngg tthhee UUnniitt

You must configure the unit so that 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. You can configure your unit locally or remotely using the following procedures:

 Use a standard Web browser to access the unit’s internal Web pages and

configure the unit over the network. This is the easiest and preferred method.

 Use a Telnet connection to configure the unit over the network.  Use a terminal or terminal emulation program to access the serial port

locally.

The unit’s configuration is stored in nonvolatile memory (NVRam) and is retained without power. You can change the configuration at any time. The unit performs a reset after the configuration has been changed and stored.

Configuring via Web Browser

If your unit already has an IP address, you can log into it using a standard Web browser with Java enabled.

1. Type the unit's IP address into the Web browser's URL (Address/Location) field.

Server Configuration (Network Configuration)

These are the unit’s basic network parameters.

Figure 3-8. Network Configuration

IP Address

The IP address must be set to a unique value in your network. See Methods of

Assigning the IP Address for more information on IP addressing.

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 that are assigned for the host section.

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

The unit prompts for the number of host bits to be entered, then calculates the netmask, which is displayed in standard decimal-dot notation when the saved parameters are displayed (for example, 255.255.255.0).

Change Telnet Configuration Password

Setting the Telnet configuration password prevents unauthorized access of the setup menu via a Telnet connection to port 9999 or via 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 window via 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 are the last six digits of the Mac address.

You can change the DHCP name (up to eight characters) when configuring the server on the Setup Mode window. 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. DHCP gives the unit a DHCP address when a LTX05 name is given.

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

Channel 1 Configuration (Serial Port Parameters)

Using this option, define how the serial port will respond to network and serial communications.

Figure 3-10. 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: If you do not want to convert the binary numbers to hexadecimals

yourself, look up the values in Table 6-6. Interface Mode Options in the Binary to Hexadecimal chapter.

Port Number

The setting represents the source port number in TCP connections, and is the number used to identify the channel for remote initiating connections. Range: 1-65535 except for the following reserved port numbers:

Port Numbers Reserved for

10001&10002 9999 Telnet setup

77FE (Hex) Configuration 7 Echo 80 Web server

Channel 1 and channel 2, respectively for use with the Com Port Redirector

Warning: We recommend that you not use the reserved port numbers

for this setting as incorrect operation may result.

The port number functions as the TCP/UDP source port number for outgoing packets. Packets sent to the unit with this port number are received to this channel. The port number selected is the Incoming TCP/UDP port and Outgoing TCP/UDP source port. Use Port 0 when you want the outgoing source port to change with each connection.

If the port number is 0, a random value of at least 50000 is used to actively establish a connection. 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.

SDS2100 User Guide 3: Configuring the Unit

Note: If you do not want to convert the binary numbers to hexadecimals

Manual Connection: When you use manual connection, you are not required to enter the entire IP address if the IP is already configured as the remote IP address in the unit. 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.

Complete override; connection is started with host 121.2.4.5, port 1

Autostart (Automatic Connection): If autostart is enabled, 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.

SDS2100 User Guide 3: Configuring the Unit

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 is able to connect to another IP in the hostlist. Only Channel 1 supports the hostlist option.

Figure 3-11. Hostlist Option

To use this ability, 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.

SDS2100 User Guide 3: Configuring the Unit

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, accumulating phone charges for each connection. Modem Mode allows you to replace modems with SDS2100s, and to use an Ethernet connection instead of a phone call, without having to change communications applications and make 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 can

still accept network TCP connections to the serial port if Connect Mode is set

C6 (no echo), D6 (echo with full verbose), or D7 (echo with 1-character

to response).

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 (no echo) refers to the modem not sending an answer to the commands received (or displaying what was typed).

To disconnect a connection using Modem Mode commands:

 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.  The unit acknowledges with an OK to indicate that it is in command mode.  Enter ATH and press Enter. It 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).

Pack Control

Two firmware-selectable packing algorithms define h ow 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 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.

SDS2100 User Guide 3: Configuring the Unit

Pack control settings are enabled in Flush Mode. Set this value to 00 if specific functions are not needed.

Note: If you do not want to convert the binary numbers to hexadecimals

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 should wait before sending accumulated characters. This wait period is between characters. If there is an idle period between characters equal to the force transmit set, then the SDS will package up the serial data currently in the buffer and send 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 fram e 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 not set, they are interpreted independently.

If Send Immediately After Send Characters is not set, any characters already in the serial buffer are included in the transmission after a "transmit" condition is found. If set, 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.

DisConnTime (Inactivity Timeout)

Use this parameter to set an inactivity timeout. The connection is dropped 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.

Send Characters

You can enter up to two characters in hexadecimal representation in the parameters "sendchar." If a character received on the serial line matches one of these

SDS2100 User Guide 3: Configuring the Unit

characters, it is sent immediately, along with any awaiting characters, to the TCP connection. This minimizes the response time for specific protocol characters on the serial line (for example, ETX, EOT, etc.). Setting the first sendchar to recognition of the characters. Alternatively, the two characters can be interpreted as a sequence (see Pack Control above).

00 disables the

Telnet Terminal Type

This parameter appears only if the terminal type option is enabled in Disconnect Mode (see DisConnMode above). If this option is enabled, you can 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, which can be used 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 (see above). If it is enabled, you can set a password on the serial port.

Port 77FE is a setting that allows the Lantronix Device Installer utility to configure the unit remotely. Disabling Port 77FE will prevent remote access to the unit from the Lantronix Device Installer utility. You can configure the unit only by using Web pages, Telnet, or serial configuration.

Disable Web Server

This setting disables the use of the Web Page Configuration tool that is built into the unit. Browser initiated sessions to port 80 on the SDS will be disabled. Configuration via HTTP will be disabled. Port 80 will be closed.

Disable ECHO Ports

This setting disables the use of the echo server that is built into the unit. The option disables support for UDP and TCP connections to port 7.

Enable Enhanced Password

This setting defaults to the N (option), which allows you to set a 4-character password that protects the Configuration Menu via Telnet and Web pages. The Y (Yes) option allows you to set an extended security password of 16-characters for protecting Telnet access.

Enable Encryption

Rijndael is the block cipher algorithm chosen by the National Institute of Science and Technology (NIST) as the Advanced Encryption Standard (AES) to be used by the US government. The SDS supports 128-, 192-, and 256-bit encryption key lengths.

Follow the steps below to configure AES encryption on the SDS.

NOTE: Configuring encryption should be done through a local connection to

the serial port of the SDS, or via a secured network connection. Initial configuration information including the encryption key are sent in clear text over the network.

1. Telnet to the configuration port on the SDS (Port 9999). An example of a Telnet command syntax is shown below. In the command

examples below, replace the x's with the IP address of the SDS.

entered in hexadecimal. The hexadecimal values are echoed as asterisks to prevent onlookers from seeing the key. Hexadecimal values are 0-9 and A-F.

 For a 128-bit key length, enter 32 hexadecimal characters.  For a 192-bit key length, enter 48 hexadecimal characters.  For a 256-bit key length, enter 64 hexadecimal characters

8. Continue pressing Enter until you return to the Change Setup menu.

9. At the Change Setup menu, select option 9 to save and exit. Encryption only applies to the port selected for data tunneling (default 10001),

regardless of whether you are using TCP or UDP. Generally, one of two situations applies:

 Encrypted SDS-to-SDS communication. Be sure to configure both SDS

devices with the same encryption key.

 Third-party application to SDS-encrypted communication: SDS uses

standard AES encryption protocols. To communicate successfully , products and applications on the peer side must use the same protocols and the same shared key as the SDS. To ease the development process, Lantronix provides an AES encryption DLL for Windows and protocol source code samples. See the document “Encryption Enabling Serial Devices” on the Lantronix web site (

www.lantronix.com) for more instructions and sample

code.

Via the Serial Port

The following procedure is for using the HyperTerminal software application. This procedure takes about 10 minutes.

Note: Do not switch off the power supply during the update. A loss of

power while reprogramming will result in a corrupt program image and a nonfunctional unit.

To download firmware from a computer via the unit’s serial port:

1. Enter Monitor Mode via the serial port (see Monitor Mode in the Troubleshooting

chapter).

2. Download the firmware to the unit using the DL command.

3. Select Send Text File and select the SD21*.HEX file to be downloaded. The

downloaded file must be the .HEX (ASCII) version.

Note: For SDS1100, select the SD11*.HEX file to be downloaded.

4. After the final record is received, the unit checks the integrity of the firmware

image before programming the new firmware in the flash ROM. The following message displays when the firmware upgrade is complete.

This chapter discusses how you can diagnose and fix errors quickl y 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 be displayed. 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.

SDS2100 User Guide 5.Troubleshooting

When you report a problem, please provide the following information:

 Your name, your company name, address, and phone number  Lantronix SDS model number  Lantronix SDS serial number  Software version (on the first screen shown when you Telnet to port 9999)  Description of the problem  Debug report (stack dump), if applicable  Status of the unit when the problem occurred (please try to include

information on user and network activity at the time of the problem)

Table 5-1. Problems and Error Messages

Note: When troubleshooting the following problems, make sure that the

SDS 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.

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 SDS via the ARP method, the “Press Enter to go into Setup Mode” error (described below) displayed. Now when you Telnet to the SDS, the connection fails.

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 is closed.

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

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 SDS, you are only assigning a temporary IP address. When you Telnet into port 9999 and do not press Enter quickly, the SDS will reboot, 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.

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.

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

Confirm that the Ethernet address that you entered with the ARP command is correct. The Ethernet address may only include numbers 09 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.

SDS2100 User Guide 5.Troubleshooting

Problem/Message Reason Solution

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

“No response from device! Verify the IP, Hardware address and Network Class. Please try again.”

No LEDs are lit. The unit or its power supply is

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

The SDS 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.

damaged, or the unit is not plugged into power properly.

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 SDS.

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

Double-check the parameters that you specified. Tip: You cannot assign an IP address to a SDS through a router.

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

The SDS2100 will not power up properly, and the LEDs are flashing.

The SDS is not communicating with the serial device attached to the SDS.

When you try to enter the setup mode on the SDS via the serial cable, you get no response.

Various Consult the LEDs section in the

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

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

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

Make sure that you are using the correct serial cable. The SDS serial port is just like a terminal serial port (DTE). The serial settings for the serial device and the SDS must match. The default serial settings for the SDS 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.

SDS2100 User Guide 5.Troubleshooting

Problem/Message Reason Solution

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

With DeviceInstaller you get the “Wrong Password” error when you try to upgrade the firmware.

You are using the correct serial cable, and the SDS should be set up correctly, but you are not communicating with your device attached to the SDS across the network.

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 SDS security settings.

The unit may have the correct IP address, but an incorrect gateway address.

You have chosen the incorrect setting for the Existing Firmware filed.

If you are sure that the serial cable is correct, then you may not be connecting to the correct socket of the SDS.

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

Turn the SDS 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 SDS) PING X.X.X.X (X.X.X.X is the IP of the SDS).

If you get a response, then there is a duplicate IP address on the network (the LEDs on the SDS 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.

Try upgrading the firmware again, but make sure to use the correct setting in the field of Existing Firmware field.

You can check to see whether there is a socket connection to or from the SDS by looking at the Status LED.

If the Status LED is blinking consistently, or is completely off, 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 SDS from the network. Use Connect Mode option C1 or C5 for a connection to the network from the SDS. See the full list of Connect Mode Options in the Binary to Hexadecimal chapter.

When connecting to the WEBManager within the SDS, the message “No Connection With The SDS” displays.

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

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 SDS.

Monitor Mode

Monitor Mode is a command-line interface used for diagnostic purposes (see Monitor

Mode Commands at the end of this section). There are two ways to enter Monitor

Mode: locally via the serial port or remotely via the network.

Via the Serial Port

To enter Monitor Mode locally, follow the same principles used in setting the serial configuration parameters:

1. To enter Monitor Mode with network connections, type xx1 or zzz (not three x

keys as you did before).

2. To enter Monitor Mode without network connections, type xx2 or yyy. A 0> prompt indicates that you have successfully entered Monitor Mode.

Via the Network

To enter Monitor Mode using a Telnet connection:

1. First establish a Telnet session. The following message displays:

Figure 5-1. Entering Monitor Mode Via the Network

*** Lantronix Secure Device Server *** MAC address 00204A0250AF Software Version 05.6b3 <040311> SDS2100 AES library version 1.8.2.1

Press Enter to go into Setup Mode _

2. Type M (upper case). A 0> prompt indicates that you have successfully entered Monitor Mode.

Monitor Mode Commands

The following commands are available in Monitor Mode. Many commands have an IP address as an optional parameter (x.x.x.x). If the IP address is given, the command is applied to another unit with that IP address. If no IP address is given, the command is executed locally.

Note: All commands must be given in capital letters, with blank spaces

between the parameters.

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 listing all configuration options in hexadecimal notation. The following tables are included:

 Binary to Hexadecimal Conversions  Connect Mode Options  Disconnect Mode Options  Flush Mode (Buffer Flushing) Options  Interface Mode Options  Pack Control Options

Converting Binary to Hexadecimal

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, 0010 0011) 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.
