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, and WP2004000-01 (WiPort-485). Chapter Summary The remaining chapters in this guide include: Introduction Describes the main features of the WiPort and the protocols it supports.
Using This Guide Additional Documentation The following guides are available on the product CD and the Lantronix web site (www.lantronix.com) 8 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 transceiver, and dual high-speed serial ports into a single compact module.
Introduction 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.
Introduction 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.
3: Configuration Using DeviceInstaller This chapter covers the steps for getting the WiPort device server online and working.

6: Configurable Pins The WiPort has eleven pins configurable for General Purpose I/O (GPIO). Note: In addition, configure these pins for serial port control lines, such as modem control in, DCD, and diagnostic outputs to LED, using DeviceInstaller. Use these GPIO pins to control devices such as relays, servers, lights, monitor switches, sensors, and even processes such as data transfer.
Configurable Pins 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. Every command consists of nine bytes: one command type of one byte and two parameters of four bytes each.
Configurable Pins 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. Command 12h, Get Active Levels Send: No parameters Response: 1 parameter Bytes 1-4: Active levels Bit X 1 means GPIO X is active low (0V when active, 3.3V when inactive). 0 means it is active high (3.3V when active, 0V when inactive).
Configurable Pins Command 1Ah, Set Active Levels 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 active type for that GPIO will not change. Bytes 5-8: New Active Levels Bit X 1 means GPIO X will become active low. 0 means it will become active high.
Configurable Pins Example 2: PC sends command 1Bh to change the current states of GPIO 0 and 1 (assuming they are configured as outputs). PC -> WiPort: 1Bh, 01h, 00h, 02h, 00h, 01h, 00h, 00h, 00h WiPort -> PC: 1Bh, 03h, 00h, 00h, 00h Command details: 1Bh = command 1Bh 01h, 00h, 00h, 00h = the mask that determines which GPIOs will be changed. Bit 0 and 9 are 1 → GPIO0 and GPIO9 will be changed. bit 1 is 0 → GPIO1 will remain the same. 01h, 00h, 00h, 00h = the new states bit 0 is 1 → GPIO0 will become 1.
7: Monitor Mode Monitor Mode is a command-line interface used for diagnostic purposes. There are two ways to enter Monitor Mode: locally via the serial port or remotely via the network. Entering Monitor Mode via the Serial Port To enter Monitor Mode locally: 1. Follow the same steps used for setting the serial configuration parameters (see Serial Port Access on page 38). 2. Instead of typing three x keys, however: a) Type zzz to enter Monitor Mode with network connections.
Monitor Mode Command Command Name Function PI x.x.x.x Ping Pings unit with IP address x.x.x.x to check device status. AT ARP Table Shows the unit’s ARP table entries. TT TCP Connection Table Shows all incoming and outgoing TCP connections. NC Network Connection Shows the unit’s current IP address. RS Reset Resets the unit. QU Quit Exits diagnostics mode. G0, G1, ....,Ge, Gf Get configuration from memory page Gets a memory page of configuration information from the device. S0, S1,...
8: Updating Firmware 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.
Updating Firmware Using TFTP: Command Line Interface To download new firmware from a computer, enter the following from a TFTP command line interface: tftp –i put 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.
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.
General DeviceInstaller Settings 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.
General DeviceInstaller Settings 74 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.
