9 2 2 : : i i n n t t r r o o d d u u c c t t i i o o n n applications the uds family of device servers allows se rial 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 ext end across a facility or around the world. the com port redirector software included on the product cd simplifies the integration process by extending the fu nctionality 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 10 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 assu re 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 ty pical datagram applications in which devices interact with other devices without maintaining a point-to-point connection.
introduction uds200 user guide 11 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 conf iguration. 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 under side 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. figure 2-2. sample hardware address 00-20-4a-14-01-18 or 00:20:4a:14:01:18

configuring the uds using telnet or the serial port uds200 user guide 27 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 forw ard 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 remo te 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 t he 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 serv er enters monitor mode. for example, if the remote ip address alr eady 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 endi ng for the connection st ring. for example, c50.1/23 would connect you to 129.1.50.1 and port 23. table 5-6. manual connection address example command string result if remote ip is 129.1.2.3 and remote port is 1234 c121.2.4.5/1 comp lete override; connection is st arted with host 121.2.4.5, port 1 c5 connect to 129.1.2.5, port 1234 c28.10/12 connect to 129.1.28.10, port 12 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 t able. 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 29 modem (emulation) mode: in modem mode, the unit presents a modem interface to the attached serial device. it accept s 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 co mmunications applications, you avoid potentially expensive phone calls. to select modem mode, set the connect mode to c6 (n o 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 se rial 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 t he 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 (n o data traffic) before sending +++. ? there must not be a break longer than 1 second between +s. ? there must be another 1-second guar dtime 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 .

configuring the uds using telnet or the serial port uds200 user guide 31 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 . table 5-8. disconnect mode options disconnect mode option bit 7 6 5 4 3 2 1 0 disconnect with dtr drop 1 ignore dtra 0 telnet mode and terminal type setup 1 1 channel (port) password 2 1 hard disconnect 3 0 disable hard disconnect 1 state led off with connection 4 1 disconnect with eot (^d) 5 1 1. the uds sends the "terminal type" upon an outgoing connection. 2. a password is required for a connecti on to the serial port from the network. 3. the tcp connection closes even if the remo te 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 connecti on is dropped. both telnet mode and disconnect with eot must be enabled for disconnect with eot to f unction 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 function bit 7 6 5 4 3 2 1 0 input buffer (serial to network) clear with active connection (from serial) 1 clear with passive connection (from network) 1 clear with disconnect 1 output buffer (network to serial) clear with active connection (from serial) 1 clear with passive connection (from network) 1 clear with disconnect 1 alternate packing algorithm (pack control) enable 1
configuring the uds using telnet or the serial port uds200 user guide 32 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 33 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 se rial 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 term inal name for the telnet terminal type. enter only one name. if the terminal type option is enabled, the uni t 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 c hannel (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 34 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 net work device is still on the network. if the unit does not receive a re sponse, 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 timi ng 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

troubleshooting and technical support uds200 user guide 45 problem/message reason solution you may have entered the ethernet address incorrectly with the arp command. 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. the ip address you are trying to assign is not on your logical subnet. 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. when you telnet to port 1 to assign an ip address to the uds, the telnet window does not respond for a long time. the uds may not be plugged into the network properly. 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. when you try to assign an ip with deviceinstaller, you get the following message: no device was found at this hardware address. 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. 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. 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 uds does not power up properly, and the leds are flashing. various consult the leds section above or 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 46 problem/message reason solution the uds is not communicating with tan attached serial device. the most likely reason is the wrong serial cable or serial settings were chosen. 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. when you try to enter setup mode on the uds using the serial cable, you get no response. the issue is likely something covered in the previous problem, or possibly you have caps lock on. double-check everything in the problem above. confirm that caps lock is not on. you can ping the uds, but not telnet to the uds on port 9999. 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. 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 47 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. 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. 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. when connecting to web manager within the uds, the message no connection with the uds displays. your computer is not able to connect to port 30718 (77feh) on the uds. 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. technical support if you are unable to resolve an issue using the information in this documentation, please contact technical support: technical support us check our online knowledge base or send a question to technical support at http://www.lantronix.com/support . technical support europe, middle east, africa phone: +33 1 39 30 41 72 email: eu_techsupp@lantronix.com or eu_support@lantronix.com firmware downloads, faqs, and the most up -to-date documentation are available at http://www.lantronix.com/support when you report a problem, please provide the following information: ? your name, and your company name, address, and phone number ? lantronix model number ? lantronix serial number

alternative ways to assign an ip address uds200 user guide 54 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, cr eate an entry in the host's arp table using the intended ip address and the ha rdware 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.
