2. Introduction This chapter summarizes the Micro125 device server’s features and the basic information needed to get started. Capabilities The Micro125 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 Micro125 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 Micro125 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, 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.
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 Micro125 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. Getting Started This chapter covers the steps required to get an embedded device physically connected. Physically Connecting the Unit The following diagram shows a properly installed Micro125.

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 When you try to assign an IP with DeviceInstaller, you get the following : "No response from device! Verify the IP, Hardware Address and Network Class. Please try again." Reason Solution 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.
12: Troubleshooting Problem/Message Reason Solution 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. You can check to see whether there is a socket connection to or from the device server by looking at the Status LED.
