2: Introduction The WiBox™ family of wireless device servers provides serial-to-wireless network connectivity. They enable virtually any serial device or equipment to be remotely accessed, controlled, monitored or shared on an 802.11b wireless network. The WiBox provides a fully integrated solution that combines an operating system, embedded Web server, and full TCP/IP protocol stack with an 802.11b transceiver supporting WEP security and two high-speed serial ports into a small compact package.
Introduction Figure 2-1. Serial Tunneling Network Example In Error! Reference source not found., a PC connected to an AP via an Ethernet connection and a PC with a wireless connection to the AP access the WiBox as though they are directly connected to it. The combination of the WiBox, a PC, and Lantronix’s Redirector behave such that it seems the PC is directly communicating to the WiBox’s serial devices without the use of the AP. However, communication is preserved through the AP.
Introduction Figure 2-3. Serial Tunneling Infrastructure Example In Error! Reference source not found., the WiBox communicates with another device server via the AP. The device server (in this example, the UDS) is connected via an Ethernet connection to the AP. As such, the WiBox and the device server communicate directly and can transfer information between their serial devices. Ad-Hoc WiBox Connection Figure 2-4.
Introduction IP for addressing, routing, and data block handling over the network. User Datagram Protocol (UDP) for typical datagram applications in which devices interact with other devices without maintaining a point-to-point connection. Configuration Methods After the physical installation of the WiBox, it requires configuration. For the unit to operate correctly on a network, it must have a unique IP address and appropriate wireless settings for network communications.

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 wbx540.rom W2 tftp –i 192.168.1.111 put H2_FW_200.fwx FWX1 tftp –i 192.168.1.111 put wbx_wm110.
9: 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 be displayed. 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.
Updating Firmware Problem/Message Reason Solution The IP address you are trying to assign is not on your logical subnet. Confirm that your PC has an IP address and that it is in the same logical subnet that you are trying to assign to the device server. 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.
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 checking the state of CP1, if it has been configured for LED1 functionality.
