  • Page 7 The three Lantronix Embedded Integration Kits (Mini-Kit, Mini100-Kit, Micro-Kit) provide an elegantly simple method of evaluating our CoBox-Mini, CoBox-Mini100, and CoBox-Micro embedded Device Servers. These kits allow software engineers to test our Device Servers with their products prior to the hardware development of those products.
  • Page 8 Embedded Device Servers Introduction Embedded Device Servers The CoBox-Mini, CoBox-Mini100, CoBox-Micro, and UDS-10B embedded Device Servers connect serial devices to Ethernet networks using the IP protocol family (TCP for connection-oriented stream applications and UDP for datagram applications). The main benefit of these smaller, board-level Device Servers is that they can be embedded inside the serial device for which they are providing network connectivity.
  • Page 9 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 (e.g., 00-20-4A), identifying the unit as a Lantronix product. The fourth, fifth, and sixth bytes are unique numbers assigned to each Device Server.

  • Page 41: Default Ip Address

    6: Getting Started This chapter covers the required steps to get the Device Server on-line and working. There are two basic methods used to log into the Device Server and setup the IP address: Network Port Login: Make a Telnet connection to the network port (9999). Serial Port Login: Connect a terminal or a PC running a terminal emulation program to the Device Server’s first serial port (CH 1).

  • Page 42: Autoip

    AutoIP Getting Started AutoIP AutoIP allows a Device Server to obtain an address in a network that does not have a DHCP server. (Windows 98 and 2000 also support AutoIP.) AutoIP assigns a random valid address to the Device Server in the range of 169.254.x.1 to 169.254.x.1(x can be between 0 and 255).

  • Page 43: Network Port Login

    Getting Started Setting the IP Address Network Port Login The ARP method is available under UNIX and Windows-based systems. The Device Server will set its address from the first directed TCP/IP packet it receives. On a UNIX host, create an entry in the host’s ARP table using the intended IP address and the hardware address of the Device Server, which is found on the product label.

  • Page 44: Serial Port Login

    Setting the IP Address Getting Started Serial Port Login Connect a console terminal or PC running a terminal emulation program to the Device Server’s first serial port (CH 1). The configuration serial port settings are 9600 baud, 8 bits, no parity, 1 stop bit. To enter Setup (configuration) Mode, cycle the Device Server’s power (power off and back on).

  • Page 45: Network Configuration Using A Web Browser

    Type the Device Server’s IP address into the Web browser’s URL (Address/ Location) field. Figure 7-1: Web Browser Login Once you have connected to the Device Server, you will see the Lantronix Web Manager interface. Select Connect to login and gain access to the configuration menu.

    Configuration Network Configuration Using UDP To enter Setup (configuration) Mode, cycle the Device Server’s power (power off and back on). After power-up, the self-test begins and the Diagnostic and Status LEDs start blinking. You must enter three lowercase “x” characters (xxx) within one second after powering up in order to start the configuration mode.

  • Page 48: Configuration Parameters

    Configuration Parameters Configuration Configuration Parameters After entering Setup Mode (confirm by pressing Enter), you can configure the parameters by entering one of the numbers on the Change Setup Menu, or you can confirm default values by pressing Enter. Be sure to store the new configurations when you are finished. The Device Server will then perform a power reset.

  • Page 49: Server Configuration

    Configuration Server Configuration Server Configuration Select 0 to configure the Device Server’s basic parameters. IP Address The IP address must be set to a unique value in your network. See Appendix E for more information about IP Addressing. Note: The Device Server cannot connect to the network if the assigned IP address is already in use by another device.

  • Page 50: Dhcp Naming

    Serial Channel (Port) Configuration Configuration DHCP Naming The DHCP name of the Device Server can be changed. The default name of the Device Server is Cxxxxxx, where xxxxxx is the last 6 digits of the Mac address. This option can be changed to LTXdd, where 0.0.0.dd is the IP address assigned (dd should be a number between 1 and 99).

    8: Using the Device Server Comm Port Redirector The Lantronix Comm Port Redirector application allows PCs to share modems and other serial devices connected to a Device Server using Windows-based applications. The Comm Port Redirector intercepts communications to specified COM ports and sends them over an IP network connection to the Device Server’s serial port.
  • Page 64 Comm Port Redirector Using the Device Server Note: When using the Redirector, the Device Server does not change its serial port configuration to match the PC application’s serial settings. Ensure that the Device Server serial port’s configuration matches the configuration of your serial device.

    Supplemental Information Network Configuration Using a Hex File To send a setup record via Monitor Mode: Configure a “master” Device Server with the desired parameters and place it on the network. Place another Device Server (the “target”) on the network. Enter Monitor Mode (with network support enabled) on the master Device Server (see Monitor Mode on page B-1) At the prompt, enter SC, the IP address of the target, and a carriage return.

  • Page 102: Ip Addresses

    IP Addresses Supplemental Information IP Addresses Each TCP/IP node on a network host has a unique IP address. This address provides the information needed to forward packets on the local network and across multiple networks if necessary. IP addresses are specified as x.x.x.x, where each x is a number from 1 to 254; for example, 192.0.1.99.

  • Page 103: Subnet Portion

    Supplemental Information IP Addresses Subnet Portion The subnet portion of the IP address represents which sub-network the address is from. Sub-networks are formed when an IP network is broken down into smaller networks using a subnet mask. A router is required between all networks and all sub-networks. Generally, hosts can send packets directly only to hosts on their own sub-network.

  • Page 104: Ip Subnet Mask

    IP Addresses Supplemental Information IP Subnet Mask An IP subnet mask divides IP address differently than the standards defined by the classes A, B, and C. An IP subnet mask defines the number of bits to be taken from the IP address as the network or host sections.

  • Page 105: Private Ip Networks And The Internet

    Supplemental Information IP Addresses Private IP Networks and the Internet If your network is not and will not be connected to the Internet, you may use any IP address. If your network is connected or will be connected to the Internet, or if you intend to operate the Device Server on an intranet, you should use one of the reserved sub-networks.

  • Page 106: Binary To Hexadecimal Conversion

    Binary to Hexadecimal Conversion Supplemental Information Binary to Hexadecimal Conversion Many of the Device Server’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. Hexadecimal digits have values ranging from 0 to F, which are represented as 0-9, A (for 10), B (for 11), etc.
