1: Using This Guide Purpose and Audience This guide provides the information needed to configure, use and update the WiPortTM and is intended for software developers and system integrators who are embedding the WiPort in their designs. This User Guide covers WiPort Device Server versions WP2001000-01, WP2002000-01, WP2004000-01 (WiPort-485), and WP2001000G-02 (WiPort-G). Note: For the WiPort model WP2001000M-02, additional information can be found in the Modbus Protocol User Guide located at www.lantronix.
Using This Guide 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.
2: Introduction 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.
Introduction 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.
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 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.

9: Troubleshooting 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.
Troubleshooting 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.
Troubleshooting 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.
Troubleshooting Problem/Message Reason Solution When connecting to the WebManager 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.
