Using This Guide WiPort™ User Guide 9 Additional Documentation The following guides are available on the product CD and the Lantronix web site (www.lantronix.com) WiPort Development Kit Quick Start Guide Briefly explains the basics to get the WiPort up and running. WiPort Integration Guide Provides information about the WiPort hardware and integrating the WiPort into another product.
WiPort™ User Guide 10 22:: IInnttrroodduuccttiioonn WiPort is a wireless embedded device server that provides a network-enabling solution based on the IEEE 802.11b wireless standard. WiPort allows Original Equipment Manufacturers (OEMs) to add wireless connectivity to their products by incorporating it onto a circuit board. The WiPort functions independently of a PC, providing a fully integrated solution that combines a processor, memory, 802.11b, 802.11g transceiver, and dual high-speed serial ports into a single compact module. It includes an operating system, an embedded Web server, and a full TCP/IP protocol stack. In addition, the WiPort sends email alerts and supports numerous other network communication protocols, including ARP, UDP, TCP, ICMP, Telnet, AutoIP, DHCP, HTTP, SNMP, and SMTP. Both Wired Equivalent Privacy (WEP) and Wireless Protected Access (WPA) are available for security. WEP uses an RC4 encryption algorithm with a 64-bit or 128-bit key. This key jumbles the data before it is sent over the airwaves. WPA is more secure because re-keying is required. With WPA, the re-keying of global encryption keys is required. This key is changed using TKIP for unicast traffic. For OEMs who wish to customize the user interface by employing common and familiar tools, the WiPort serves applets to a Web browser, resulting in interactive Web pages. This customization of HTML Web pages and configuration screens tailors the WiPort to fit unique requirements. Capabilities The WiPort device server has the following capabilities:  Communication between TCP and UDP to serial.  Wireless interface (802.11b and 802.11g) with WEP or WPA protection.  Ethernet interface.  Email notification of configurable alarms and events.  Upgradeable firmware.  SNMP monitoring.  Connects devices through a TCP or UDP data channel to computers or to another device server.  Contains a web server allowing presentation of custom content and easy configuration through the browser.  Contains eleven programmable I/O pins used to monitor or control attached devices. Applications The WiPort device server connects serial devices such as those listed below to wireless and Ethernet networks using the IP protocol family.
Introduction WiPort™ User Guide 11  Remote sensing  CNC controllers  Data collection devices  Telecommunications equipment  Data display devices  Security alarms and access control devices  Time clocks and terminals Protocol Support The WiPort device server uses the TCP/IP protocol stack for network communications. Other supported protocols include:  ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP for network communications and management.  TCP, UDP, and Telnet for connections to the serial port.  TFTP for firmware and web page 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.  SMTP for e-mail transmission. Configuration Methods 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 device server: DeviceInstaller: View the current WiPort configuration using a Graphical User Interface (GUI) on a PC attached to a network. (See 3:Using DeviceInstaller.) Web-Manager: Through a web interface, configure the WiPort and its settings using the WiPort’s Web-Manager. (See 4:Configuration Using Web-Manager.) Serial & Telnet Ports: There are two approaches to accessing Serial Mode. Make a Telnet connection to the network port (9999) or connect a terminal (or a PC running a terminal emulation program) to the unit’s serial port. (See 5:Configuration via Serial Mode or Telnet Port.) Addresses and Port Numbers Hardware Address The hardware address is also referred to as the Ethernet 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. Example: 00-20-4A-14-01-18 Note: Make note of the MAC address. It is needed to locate the WiPort using DeviceInstaller.
Introduction WiPort™ User Guide 12 IP Address Every device connected to an IP network must have a unique IP address. This address is used to reference the specific unit. The WiPort is automatically assigned an IP address on DHCP-enabled networks as it is DHCP-enabled by default. Port Numbers 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 phone 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. Ports 0-1024 are reserved as well. For more information on reserved port numbers, refer to Table 5-6. Reserved Port Numbers.

As an alternative to Web-Manager, the WiPort unit is configurable using a terminal program to access the serial port locally. Using this terminal program to respond to prompts is referred to as the Setup Mode. A Telnet connection may also be used to configure the unit over the network. The unit’s configuration is stored in nonvolatile memory and is retained without power. You can change the configuration at any time. The unit performs a reset after the configuration has been changed and stored. Note: The menus in this section show a typical device. Not all devices display information in the same manner. Accessing Setup Mode Telnet Access Note: Alternatively, use DeviceInstaller to access Telnet. Select the device from the main window list, and click the Telnet Configuration tab in the right window. If using Telnet from the DeviceInstaller toolbar, skip steps 1 through 3. To configure the unit over the network, establish a Telnet connection to port 9999: 1. From the Windows Start menu, click Run. 2. From the Run dialogue box, type the following command (where x.x.x.x is the IP address and 9999 is the unit’s fixed network configuration port number): Windows: telnet x.x.x.x 9999 UNIX: telnet x.x.x.x:9999 3.

Server Configuration The unit’s basic server (i.e. network) values display upon selecting Server (option 0 from the Change Setup menu). The following sections describe the configurable parameters within the Server configuration menu. Set the IP Address If DHCP is not used to assign IP addresses, enter it manually. The IP address must be set to a unique value in the network. Enter each octet and press Enter between each section inputted. The current value is displayed in parentheses. IP Address : ( 0) ( 0) ( 0) ( 0) _ Set the 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. The default is N (No), indicating the gateway address has not been set. To set the gateway address, type Y. At the prompt, enter the gateway address. Set Gateway IP Address (N) ? Y Gateway IP addr ( 0) ( 0) ( 0) ( 0)_ Set the Netmask A netmask defines the number of bits taken from the IP address that are assigned for the host part. Netmask: Number of Bits for Host Part (0=default) (0) _ The unit prompts for the number of host bits to be entered, then calculates the netmask, which displays in standard decimal-dot notation when the saved parameters are displayed (for example, 255.255.255.0).

The password must have 4 characters. Change telnet config password (N) ? _ An enhanced password setting (for Telnet access only) of 16 characters is available under option 6 Security from the Change Setup menu. Note: A password is not required to access the Setup Mode window via a serial connection. DHCP Name If a DHCP server has automatically assigned the IP address and network settings, discover the unit by using the DeviceInstaller network search feature. There are three methods for assigning DHCP names to the unit.  Default DHCP Name: If the DHCP name is not changed and the IP is 0.0.0.0, then the DHCP name defaults to CXXXXXX (XXXXXX is the last 6 digits of the MAC address shown on the label on the bottom/side of the unit). For example, if the MAC address is 00-20-4A-12-34-56, then the default DHCP name is C123456.  Custom DHCP Name: Create your own DHCP name. If using an IP address of 0.0.0.0, then the last option in Server configuration is Change DHCP device name. This option allows you to change the DHCP name to an alphanumeric name (LTX in the example). Change DHCP device name (not set) ? (N) Y Enter new DHCP device name : LTX  Numeric DHCP Name: You can change the DHCP name by specifying the last octet of the IP address. When you use this method, the DHCP name is LTXYY where YY is what you chose for the last octet of the IP address. If the IP address you specify is 0.0.0.12, then the DHCP name is LTX12. This method only works with 2 digit numbers (0-99). SHOULD IT BE 10-99? The third octet of the IP address sets the BootP/DHCP/AutoIP options. To disable an option, set the appropriate bit: 5-2. BootP/DHCP/AutoIP options Options Bit AutoIP 0 DHCP 1
Configuration via Serial Mode or Telnet Port WiPort™ User Guide 39 Options Bit BootP 2 For example, if the third octet is 0.0.5.0, the AutoIP and BootP options are disabled; only DHCP is enabled. (The value 5 results from adding the binary equivalents of 0 and 2.) This is the most common setting when using DHCP. Channel 1 and Channel 2 Configuration Select option 1 Channel 1 or 2 Channel 2 from the Change Setup menu to define how the serial port responds to network and serial communications. The following sections describe the configurable parameters within the Channel configuration menu. Figure 5-5. Serial and Telnet Port Parameters 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, 115200, 230400, 460800, or 921600. The current value is displayed in parentheses. Baudrate (9600) ? _ I/F (Interface) Mode The Interface (I/F) Mode is a bit-coded byte entered in hexadecimal notation. The current value is displayed in parentheses.

It is the number that identifies the channel for remote initiating connections. 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. Port No (10001) ? _ The current value is displayed in parentheses. The default setting for Port 1 is 10001. The range is 1-65535, except for the following reserved port numbers:

With a Specific Start Character Attempts to connect when it receives a specific start character from the serial port. The default start character is carriage return.
Configuration via Serial Mode or Telnet Port WiPort™ User Guide 44 Manual Connection 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 can include a destination port number. The IP address must be in standard dot-decimal notation and may be a partial address, representing the least significant 1, 2, or 3 bytes of the remote IP address. The period is required between each pair of IP address numbers. If present, the port number must follow the IP address, must be presented as a decimal number in the range 1-65535, and must be preceded by a forward slash (ASCII 0x2F). The slash separates the IP address and the port number. If you omit the port number from a command string, the internally stored remote port number starts a connection. If a partial IP address is presented in a command string, it is interpreted to be the least significant bytes of the IP address and uses the internally stored remote IP address to provide the most significant bytes of the IP address. If the IP address entered is 0.0.0.0/0, the device server enters Monitor Mode. For example, if the remote IP address already configured in the unit is 129.1.2.3, then an example command string would be C3/7. (This would connect to 129.1.2.3 and port 7.) You may also use a different ending for the connection string. For example, C50.1/23 would connect you to 129.1.50.1 and port 23. Table 5-8.

Configuration via Serial Mode or Telnet Port WiPort™ User Guide 45 Hostlist If this option is set to True, the device server scrolls through the host list until it connects to the first available device listed in the host list table. Once it connects, the unit stops further attempts. If this connection fails, the unit continues to scroll through the table until it is able to connect to the next available IP address in the host list. Hostlist supports a minimum of 1 and a maximum of 12 entries. Each entry contains the IP address and the port number. The hostlist is disabled for Manual Mode and for Modem Mode. The unit will not accept a data connection from a remote device when the hostlist option is enabled. Figure 5-6. Hostlist Example Baudrate (9600) ? I/F Mode (4C) ? Flow (00) ? Port No (10001) ?

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 WiPorts, 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 numeric 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 to C6 (no echo), D6 (echo with full verbose), or D7 (echo with numeric response). Without Echo In Modem Mode, echo refers to the echo of all of the characters entered in command mode; it does not mean to echo data that is transferred. Quiet Mode (without echo) refers to the modem not sending an answer to the commands received (or displaying what was typed). Data Echo & Modem Response Full Verbose: The unit echoes modem commands and responds to a command with a message string shown in the table below. Numeric Response: The unit echoes modem commands and responds to a command with a numeric response. Modem Responses Only Full Verbose: The unit echoes modem commands and responds to a command with a message string shown in the table below. Numeric Response: The unit echoes modem commands and responds to a command with a numeric response.
Configuration via Serial Mode or Telnet Port WiPort™ User Guide 47 Table 5-9. Modem Mode Messages Message Meaning Full Verbose OK Command was executed without error. CONNECT A network connection has been established. NO CARRIER A network connection has been closed. RING n.n.n.n. A remote device, having IP address n.n.n.n, is connecting to this device. Numeric Response 0 OK 1 Connected 2 Ring 3 No Carrier 4 Error Received commands must begin with the two-character sequence AT and be terminated with a carriage return character. The unit ignores any character sequence received not starting with AT, and only recognizes and processes single AT-style commands. The unit treats compound AT commands as unrecognized commands. If the Full Verbose option is in effect, the unit responds to an unrecognized command string that is otherwise formatted correctly (begins with AT and ends with carriage return) with the "OK" message and takes no further action. If the Numeric Response option is in effect, the unit responds to an unrecognized command string that is otherwise formatted correctly with the "OK" message and takes no further action. When an active connection is in effect, the unit transfers data and does not process commands received from the serial interface. When a connection is terminated or lost, the unit reverts to command mode. When an active connection is in effect, the unit terminates the connection if it receives the following sequence from the attached serial device:  No serial data is received for one second.  The character sequence +++ is received, with no more than one second between each two characters.  No serial data is received for one second after the last + character. At this time, the unit responds affirmatively per the selected echo/response mode.  The character string ATH is received, terminated with a carriage return. The unit responds affirmatively according to the selected echo/response mode and drops the network connection. The serial interface reverts to accepting command strings.
Configuration via Serial Mode or Telnet Port WiPort™ User Guide 48 If this sequence is not followed, the unit remains in data transfer mode. Table 5-10. Modem Mode Commands Modem Mode Command Function ATDTx.x.x.x,pppp or ATDTx.x.x.x/pppp Makes a connection to an IP address (x.x.x.x) and a remote port number (pppp). ATDTx.x.x.x Makes a connection to an IP address (x.x.x.x) and the remote port number defined within the unit. ATD0.0.0.0 Forces the unit into Monitor Mode. Uses remote IP address and port settings to initiate a connection. ATD or ATDT Forces the unit into Monitor Mode. Uses remote IP address and port settings to initiate a connection. ATDx.x.x.x Makes a connection to an IP address (x.x.x.x) and the remote port number defined within the unit. ATH Hangs up the connection (Entered as +++ ATH ). ATS0=n Enables or disables connections from the network going to the serial port. n=0 disables the ability to make a connection from the network to the serial port. n=1-9 enables the ability to make a connection from the network to the serial port. n>9 is invalid. ATEn Enables or disables character echo and responses. n=0 disables character echo and responses. n=1 enables character echo and responses. ATVn Enables numeric response or full verbose. n=0 enables numeric response. n=1 enables full verbose. Note: The unit recognizes these AT commands as single commands such as ATE0 or ATV1; it does not recognize compound commands such as ATE0V. Send the Escape Sequence (+++) in Modem Mode Send ‘+++’ in Modem Mode (Y) ? _ Disable or enable the WiPort’s ability to send the escape sequence. The default is Y (Yes) (send the escape sequence). Auto Increment Source Port Auto increment source port (N) ? _ Y (Yes) auto increment the source port. The WiPort increments the port number used with each new connection. Remote IP Address This is the destination IP address used with an outgoing connection.

Reference source not found. on page 42 for more information). Remote Port You must set the remote TCP port number for the unit to make outgoing connections. This parameter defines the port number on the target host to which a connection is attempted. Remote Port ( 0) ? _ 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). Note: This option is not displayed when Hostlist is enabled from the ConnectMode prompt (see Error! Reference source not found. on page 42 for more information). DisConnMode Disconnect Mode (DisConnMode) determines the conditions under which the unit will cause a network connection to terminate. The current value is displayed in parentheses. DisConnMode ( 0) ? _ In DisConnMode, modem_control_in either drops the connection or is ignored. The following table displays the available input options: Table 5-11.

(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. (6) When modem_control_in transitions from a high state to a low state, the network connection to or from the serial port drops.
Configuration via Serial Mode or Telnet Port WiPort™ User Guide 50 Flush Mode The FlushMode (buffer flushing) parameter controls line handling and network buffers with connection startup and disconnect. FlushMode ( 0) ? _ Select between two different packing algorithms (the current configuration is displayed within the parentheses). Available Flush Mode options are: Table 5-12. Flush Mode Options Function 7 6 5 4 3 2 1 0 Input Buffer (Serial to Network) Clear with a connection that is initiated from the device to the network 1 Clear with a connection initiated from the network to the device 1 Clear when the network connection to or from the device is disconnected 1 Output Buffer (Network to Serial) Clear with a connection that is initiated from the device to the network 1 Clear with a connection initiated from the network to the device 1 Clear when the network connection to or from the device is disconnected 1 Alternate Packing Algorithm (Pack Control) Enable 1 Pack Control The packing algorithm defines how and when packets are sent to the network. The standard algorithm is optimized for applications in which the unit is used in a local environment. The alternate packing algorithm minimizes the packet count on the network and is especially useful in applications in a routed Wide Area Network (WAN). Adjusting parameters in this mode can economize the network data stream. Pack control settings are enabled in Flush Mode. Set this value to 00 if specific functions are not needed. Table 5-13. Pack Control Options Option 7 6 5 4 3 2 1 0 Packing Interval Interval: 12ms 0 0 Interval: 52ms 0 1 Interval: 250ms 1 0
Configuration via Serial Mode or Telnet Port WiPort™ User Guide 51 Option 7 6 5 4 3 2 1 0 Interval: 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 Packing Interval: Packing Interval defines how long the unit should wait before sending accumulated characters. This wait period is between successive network segments containing data. For alternate packing, the default interval is 12 ms. Trailing Characters: In some applications, CRC, Checksum, or other trailing characters follow the end-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 Characters is not set, any characters already in the serial buffer are included in the transmission after a "transmit" condition is found. If this option is set, the unit sends immediately after recognizing the transmit condition (sendchar or timeout). Note: A transmission might occur if status information needs to be exchanged or an acknowledgment needs to be sent. DisConnTime (Inactivity Timeout) Use this parameter to set an inactivity timeout. The unit drops the connection if there is no activity on the serial line before the set time expires. Enter time in the format mm:ss, where m is the number of minutes and s is the number of seconds. DisConnTime (0: 0) ?: To disable the inactivity timeout, enter 00:00. Range is 0 (disabled) to 5999 seconds (99 minutes, 59 seconds). The default is 0. SendChar 1 and SendChar2 Enter up to two characters in hexadecimal representation. SendChar 1 ( 0) ? _ SendChar 2 ( 0) ? _ 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
Configuration via Serial Mode or Telnet Port WiPort™ User Guide 52 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 50).
Configuration via Serial Mode or Telnet Port WiPort™ User Guide 53 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, which can be used for applications such as terminal emulation to UNIX hosts. Channel (Port) Password This parameter appears only if the channel (port) password option is enabled in Disconnect Mode. If the option is enabled, set a password on the serial port. Email Configuration Note: You can change these settings using Telnet, a serial connection, or Web-Manager with firmware versions 6.xxx or later. Earlier versions do not allow you to configure email triggers using Web Manager. To configure email settings using DeviceInstaller, see Email Notification in the DeviceInstaller online Help. The unit sends an Email to multiple recipients when a specific trigger event occurs. There are three separate triggers, based on any combination of the configurable pins (PIO) when selected as user I/O functions. Optionally, use a two-byte serial string to initiate a trigger.

Caution: Only an expert should change these parameters. These changes hold serious consequences. TCP Keepalive Time TCP Keepalive time defines how many seconds the unit waits during a silent connection before checking whether the currently connected network device is still on the network. If the unit does not receive a response, it drops that connection. TCP Keepalive time in s (1s – 65s; 0s=disable): (45)? _ ARP Cache Timeout When the unit communicates with another device on the network, it adds an entry into its ARP table. ARP Cache timeout defines the number of seconds (1-600) the unit waits before timing out this table. ARP Cache timeout in s (1s – 65s; 0s=disable): (600)? _ Enable High Performance This option allows you to increase the CPU performance and use the higher baud rates on the serial interface (460 Kbps and 920 Kbps). The standard CPU performance mode supports up to 230400 baud. Enable High Performance (n)? Note: If a baud rate of 460 Kbps or 920 Kbps is set and the high performance mode disabled, the operation of the serial channel would be out of the specified error tolerance, thereby leading to inconsistent speed settings on the two ends of the serial channel. Note: Increasing CPU clock speed consumes more power and generates more heat. This reduces the maximum operating temperature specification. See the appropriate product brief for details.

WiPort™ User Guide 64 66:: CCoonnffiigguurraabbllee PPiinnss The WiPort has eleven pins configurable for General Purpose I/O (GPIO). Use these GPIO pins to control devices such as relays, servers, lights, monitor switches, sensors, and even processes such as data transfer. Defaults Settings:  Function: general purpose input/output  Direction: input  Active Level: low Set the functions for the three pins independently and in any combination. The initial directions (input/output) and active levels (low or high active) at boot up can also be configured through 77FE. This chapter describes how the directions, active levels, and states can be dynamically controlled and probed through special port 77F0. Features:  TCP and UDP can be used.  The protocol supports up to 32 GPIO for future products.  Function configuration can be retrieved.  Input or output selection can be retrieved and controlled.  Active low or high selection can be retrieved and controlled.  Active or inactive selection can be retrieved and controlled.  77F0 can be disabled. Every change of state (active/inactive) requires a command over TCP or UDP, and thus is not very fast. If you use this port for data transfer, the throughput is low, usually up to 1Kbps. Control Protocol The GPIO control protocol is a simple, proprietary protocol, which is described below. Guidelines The GPIO control protocol is described from the PC side. Send means from PC to WiPort. Response comes from WiPort to PC. The protocol allows for control of up to 11 GPIOs. How many are actually available depends on the product. WiPort has only three. The parameters are four bytes long and represent GPIOs 0-31, with GPIO0 in bit 0 of the first byte (Little Endian). Parameter bits for configurable pins not configured as GPIOs are undefined for Get commands and ignored on Set commands.
Configurable Pins WiPort™ User Guide 65 Every command consists of nine bytes: one command type of one byte and two parameters of four bytes each.

For UDP, command type and parameters need to be in the same datagram. Responses to valid commands are always five bytes long, consisting of the returned command byte and as parameters in the current or updated values. In case of an invalid command, only one byte with value 0FFh is returned. Command Parameter 1 Byte 0 1 2 3 4 Pin Number 0 7 8 15 16 23 24 31 When sending a command (TCP and UDP), wait for the response before sending the next command. Commands Byte 0 Command Types 10h Get functions 11h Get directions (input or output) 12h Get active levels (high active or low active) 13h Get current states (active or not active) 19h Set directions 1Ah Set active levels 1Bh Set current states As you can, see there is no Set functions command. Since the pin’s function depends on the hardware in which the WiPort is embedded, that configuration is only allowed via 77FE. Settings changed by any of the Set commands are not stored and are lost when the unit is powered down or rebooted.

WiPort™ User Guide 71 88:: UUppddaattiinngg FFiirrmmwwaarree This chapter explains how to obtain and update the unit’s firmware. Obtaining Firmware Obtain the most up-to-date firmware and release notes for the unit from the Lantronix web site (www.lantronix.com) or by using anonymous FTP (ftp.lantronix.com/pub). Reloading Firmware There are several ways to update the unit's internal operational code (*.ROM and *.FWX): via DeviceInstaller (the preferred way), via TFTP, or via the serial port. You can also update the unit's internal Web interface (*.COB) via TFTP or DeviceInstaller. Here are typical names for those files. Check the Lantronix web site for the latest versions and release notes. Table 8-1. Firmware Files ROM File FWX File COB WPTxxx.ROM H2_FW_200.FWX WPT_WNxxx.COB (Web-Manager) Please refer to the DeviceInstaller User Guide for information about reloading firmware using DeviceInstaller. The other methods are discussed below: Using TFTP: Graphical User Interface To download new firmware from a computer: 3. Use a TFTP client to put a binary file to the unit (*.ROM to upgrade the unit's internal operational code and *.COB to upgrade its internal Web interface). Note: TFTP requires the .ROM (binary) version of the unit's internal operational code. 4. In the TFTP server field, enter the IP address of the unit being upgraded. 5. Select Upload operation and Binary format. 6. Enter the full path of the firmware file in the Local file name field. 7. In the Remote file name field, enter the current internal operational code or WEB1 to WEB28 for the internal Web interface with 2MB flash, or WEB1 to WEB28 or WEB60 for 4MB flash. (For WP2001000-01 and WP2002000-01 models, W1= ROM file. For WP2004000-01 models, W3=ROM file. FWX1 = FWX file.) 8. Click the Upload Now button to transfer the file to the unit. The unit performs a power reset after the firmware has been loaded and stored.
Updating Firmware WiPort™ User Guide 72 Using TFTP: Command Line Interface To download new firmware from a computer, enter the following from a TFTP command line interface: tftp –i <ip address> put <local filename> <destination file name> The following examples demonstrate the TFTP command sequence to download the .rom file, the .fwx file, and the .cob file: tftp –i 192.168.1.111 put wpt540.rom W1 tftp –i 192.168.1.111 put H2_FW_200.fwx FWX1 tftp –i 192.168.1.111 put wpt_wm110.cob WEB1 Recovering the Firmware Using the Serial Port If for some reason the firmware is damaged, you can recover the firmware file by using the serial port to download the *.ROM file. 1. Start DeviceInstaller. 2. From the Tools menu, select Advanced/Recover Firmware. The Recover Firmware window displays. 3. Enter the com port on your PC and the location of the firmware file. The Device Model should indicate WiPort. 4. Click OK to download the file. Note: See also Recovering Firmware in the DeviceInstaller User Guide.
WiPort™ User Guide 73 99:: TTrroouubblleesshhoooottiinngg This chapter discusses how you can diagnose and fix errors quickly without having to contact a dealer or Lantronix. The WiPort’s diagnostic LEDs indicate the unit’s status. 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. When troubleshooting the following problems, make sure that the WiPort is powered up. Confirm that you are using a good network connection.

Troubleshooting WiPort™ User Guide 74 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. Your currently logged-in user does not have the right to use this command on this PC. Have someone from your IT department log you in with sufficient rights. When you attempt to assign an IP address to the unit by the ARP method and Telnet to the device server through port 1, the connection fails. When you Telnet to port 1 on the device server, you are only assigning a temporary IP address. When you Telnet into port 9999 and do not press Enter quickly, the device server reboots, causing it to lose the IP address. Telnet back to Port 1. Wait for it to fail, then Telnet to port 9999 again. Make sure you press Enter within 5 seconds. When you Telnet to port 9999, the Press Enter to go into Setup Mode message displays. However, nothing happens when you press Enter, or your connection is closed. You did not press Enter quickly enough. You only have 5 seconds to press Enter before the connection is closed. Telnet to port 9999 again, but press Enter as soon as you see the Press Enter to go into Setup Mode message. You may have entered the Ethernet address incorrectly with the ARP command. Confirm that the Ethernet address that you entered with the ARP command is correct. The Ethernet address may only include numbers 0-9 and letters A-F. In Windows and usually in Unix, the segments of the Ethernet address are separated by dashes. In some forms of Unix, the Ethernet address is segmented with colons. 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 device server. When you Telnet to port 1 to assign an IP address to the device server, the Telnet window does not respond for a long time. The device server 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 device server is not properly plugged into the network. 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. 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. Double-check the parameters that you specified. Note: You cannot assign an IP address to a device server through a router.
Troubleshooting WiPort™ User Guide 75 Problem/Message Reason Solution You did not choose the correct subnet mask. The device server is not communicating with the serial device it is attached to. The most likely reason is the wrong serial settings were chosen. The serial settings for the serial device and the device server must match. The default serial settings for the device server are RS-232, 9600 baud, 8 character bits, no parity, 1 stop bit, no flow control. When you try to enter the setup mode on the device server via the serial port, you get no response. The issue is most 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 device server, but not Telnet to the device server on port 9999. There may be an IP address conflict on your network You are not Telnetting to port 9999. The Telnet configuration port (9999) is disabled within the device server security settings. Turn the device server off and then issue the following commands at the DOS prompt of your computer: ARP -D X.X.X.X (X.X.X.X is the IP of the device server). PING X.X.X.X (X.X.X.X is the IP of the device server). If you get a response, then there is a duplicate IP address on the network. If you do not get a response, use the serial port to verify that Telnet is not disabled. The device server appears to be set up correctly, but you are not communicating with your device attached to the device server across the network. If you are sure that the serial port setting is correct, then you may not be connecting to the correct socket of the device server. Another possibility is that the device server is not set up correctly to make a good socket connection to the network. You can check to see whether there is a socket connection to or from the device server by checking the state of CP1, if it has been configured for LED1 functionality. If the state of CP1 is blinking consistently, or is completely off, then there is a good socket connection. If the state of CP1 is low, use the Connect Mode option C0 for making a connection to the device server from the network. Use Connect Mode option C1 or C5 for a connection to the network from the device server. See the full list of Connect Mode options in Connect Mode on page 42.
Troubleshooting WiPort™ User Guide 76 Problem/Message Reason Solution When connecting to the Web-Manager within the device server, the No Connection With The Device Server message displays. Your computer is not able to connect to port 30718 (77FEh) on the device server. Make sure that port 30718 (77FEh) is not blocked with any router that you are using on the network. Also, make sure that port 77FEh is not disabled within the Security settings of the device server.
