2. Introduction This chapter summarizes the xPico device server’s features and the basic information needed to get started. Capabilities The xPico device server has the following capabilities: Connects devices through a TCP data channel or through a Telnet connection to computers or to another device server. The xPico also supports UDP datagrams. Contains a web [HTTP] server allowing presentation of custom content and easy configuration through a browser.
2: Introduction Protocol Support The xPico device server uses the Internet Protocol (IP) for network communications. It uses the Transmission Control Protocol (TCP) to assure that no data is lost or duplicated, and that everything sent to the connection arrives correctly at the target. Supported protocols include: ARP, TCP/IP, UDP/IP, BOOTP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP for network communications and management. TCP/IP, UDP/IP, and Telnet for connections to the serial port.
2: Introduction 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 xPico 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.
3. Using DeviceInstaller This chapter covers the steps for getting the xPico device server online and viewing its current configuration. Note: DeviceInstaller is a free utility program provided by Lantronix that discovers, configures, upgrades, and manages Lantronix Device Servers. It can be downloaded from the Lantronix website at www.lantronix.com/support/downloads.

7: Setup Mode: Channel Configuration b) Response Character Response A single character is transmitted to the serial port when there is a change in connection state: C = connected, D = disconnected, N = host unreachable. The IP address of the host connecting to the CoBos device will be provided when you use verbose mode. This option is overridden when the Active Start Modem Mode or Active Start Host List is in effect. Default setting is Nothing (quiet).
7: Setup Mode: Channel Configuration 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 may be a destination port number.
7: Setup Mode: Channel Configuration Command String Result if remote IP is 129.1.2.3 and remote port is 1234 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. 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 and Modem Modes.
7: Setup Mode: Channel Configuration d) Datagram Type Directed UDP When selecting this option, you are prompted for the Datagram type. Enter 01 for directed or broadcast UDP. Datagrams of type 01 can be sent as a broadcast by enabling the Send as Broadcast option. The default is not to broadcast. When the UDP option is in effect, the unit never attempts to initiate a TCP connection because it uses UDP datagrams to send and receive data.
7: Setup Mode: Channel Configuration Message Meaning 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.
7: Setup Mode: Channel Configuration Modem Mode Command Function ATD0.0.0.0 Forces the unit into Monitor Mode if a remote IP address and port number are defined within the unit. ATD or ATDT Forces the unit into Monitor Mode if a remote IP address and port number are not defined within the unit.

The unit sends the Terminal Type upon an outgoing connection. (2) A password is required for a connection to the serial port from the network. (3) The TCP connection closes even if the remote site does not acknowledge the disconnection.
7: Setup Mode: Channel Configuration Pack control settings are enabled in Flush Mode. Set this value to 00 if you do not need specific functions. Note: All bit positions in the table that are blank represent “don’t care” bits, for that particular option, which can be set to either a 0 or 1 value. Table 7-11.
7: Setup Mode: Channel Configuration DisConnTime (Inactivity Timeout) Use this parameter to set an inactivity timeout. The unit drops the TCP connection to the local port 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 (00:00) ?: To disable the inactivity timeout, enter 00:00. Range is 0 (disabled) to 5999 seconds (99 minutes, 59 seconds). Default is 0.
8. Setup Mode: Advanced Settings Expert Settings (Option 5) Note: You can change the Enable alternate MAC setting using telnet or serial connections only. It is not available through the Web-Manager. CAUTION: Only an expert should change these parameters. You must definitely know the consequences the changes might have. Figure 8-1.
8: Setup Mode: Advanced Settings ARP Cache timeout in seconds Whenever the unit communicates with another device on the network, it adds an entry into its ARP table. The ARP Cache timeout option allows you to define how many seconds (1-600) the unit will wait before timing out this table. ARP Cache timeout in s (1s - 600s) : (600) ? CPU Performance This option allows you to increase the CPU performance required to use the higher baud rates on the serial interface (460800 bps and 921600 bps).
8: Setup Mode: Advanced Settings TCP Re-Transmission Timeout The TCP Re-Transmission Timeout is the interval to wait for acknowledgement of transmitted TCP segments before re-transmitting them. Enter between 500 and 4000 ms. The default is 500 ms. TCP Re-transmission Timeout (500 - 4000) (ms): (500) ? Enable alternate MAC If necessary, enable the alternate MAC address (if specified in the OEM setup record).

9. GPIO Interface Configurable Pins The xPico has eight pins (CP1-8) that you can configure for General Purpose I/O (GPIO). Note: You can also configure the pins for serial port control lines, such as hardware control, modem control (CTS, RTS, DTR, and DCD), and diagnostic outputs to LED, using DeviceInstaller. You can use these GPIO pins to control devices such as relays, servers, lights, monitor switches, sensors, and even processes such as data transfer.
9: GPIO Interface Control Protocol The GPIO control protocol is a simple, proprietary protocol. Guidelines The GPIO control protocol is described from the PC side. Send means from PC to xPico. Response comes from xPico to PC. The protocol allows for control of up to 32 GPIOs. How many are actually available depends on the product. xPico has only eight. The parameters are four bytes long and represent GPIOs 0-31, with GPIO0 in bit 0 of the first byte (Little Endian).
9: GPIO Interface Command 10h, Get Functions Send: No parameters Response: 1 parameter Bytes 1-4: Functions Bit X 1 means general purpose I/O available to the user. 0 means dedicated function (e.g., serial flow control, diagnostics) for configurable pin X. Command 11h, Get Directions Send: No parameters Response: 1 parameter Bytes 1-4: Directions Bit X 1 means GPIO X is an output. 0 means it is an input.
9: GPIO Interface Command 19h, Set Directions Send: 2 parameters Bytes 1-4: Mask Bit X 1 means the direction for GPIO X will be updated with the value in the second parameter. 0 means the direction for that GPIO will not change. Bytes 5-8: New Directions Bit X 1 means GPIO X will become an output. 0 means it will become an input.
9: GPIO Interface 10h = command 10h 00h, 00h, 00h, 00h = ignored 00h, 00h, 00h, 00h = ignored Response details: 10h = response to command 10h 03h, 00h, 00h, 00h = bits 0 and 1 are 1 →CP1 and CP2 are configured as GPIOs. bit 2 is 0 → CP3 is configured as either serial control or diagnostics. The other bits are ignored because there are only eight configurable pins on the xPico. Example 2: PC sends command 1Bh to change the current states of GPIO 0 and 1.
10. Firmware Upgrades Obtaining Firmware You can obtain the most up-to-date firmware and release notes for the unit from the Lantronix web site (www.lantronix.com/support/downloads) or by using anonymous FTP (ftp.lantronix.com/pub). Reloading Firmware There are several ways to update the unit's internal operational code (*.ROM): using DeviceInstaller (the preferred way), using TFTP, or using the serial port. You can also update the unit's internal Web interface (*.COB) using TFTP or DeviceInstaller.
10: Firmware Upgrades Figure 10-1. TFTP Window 6. Click the Put button to transfer the file to the unit. The unit performs a power reset after the firmware has been loaded and stored. After the firmware has been loaded and stored, which takes approximately 8 seconds to complete, the unit performs a power reset. Using TFTP: Command Line Interface To download new firmware from a computer: 1.
10: Firmware Upgrades Recovering the Firmware Using the Serial Port and DeviceInstaller If for some reason the firmware is damaged, you can recover the firmware file by using DeviceInstaller to download the *.ROM file over the serial port. To recover firmware: 1. Start DeviceInstaller. If your PC has more than one network adapter, a message displays. Select an adapter and click OK. 2. From the Tools menu, select Advanced/Recover Firmware. The Serial Port Firmware Upgrade window displays. 3.
11. Monitor Mode Monitor Mode is a command-line interface used for diagnostic purposes. There are two ways to enter Monitor Mode: locally using the serial port or remotely using the network. Entering Monitor Mode Using the Serial Port To enter Monitor Mode locally: 1. Follow the same steps used for setting the serial configuration parameters (see Serial Port on page 35). 2. Instead of typing three x keys, however: 3. Type zzz (or xx1) to enter Monitor Mode with network connections. 4.

12. Troubleshooting This chapter discusses how you can diagnose and fix errors quickly without having to contact a dealer or Lantronix. It helps to connect a terminal to the serial port while diagnosing an error to view summary messages that may display. When troubleshooting, always ensure that the physical connections (power cable, network cable, and serial cable) are secure. Note: Some unexplained errors might be caused by duplicate IP addresses on the network.
12: Troubleshooting Problem/Message Reason Solution 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. 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.
12: Troubleshooting Problem/Message Reason Solution 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 Turn the device server off and then issue the following commands at the DOS prompt of your computer: You are not Telneting to port 9999. The Telnet configuration port (9999) is disabled within the device server security settings.
