4.2 Appendix B - Lantronix WiPort NR Device Manager

The acquisition module uses an embedded Lantronix Wi-Port module to provide the low-latency network interface. The device can normally be accessed using a web-interface as described in section 3.2.

If this is not possible configuration of the interface can be carried out using the Lantronix' DeviceInstaller utility for Microsoft Windows, using a DHCP server or the via the serial port. You will need a PC with a network interface installed or an RS232 connector.

• Download and install the DeviceInstaller utility from the Lantronix Web site at www.lantronix.com.

  DeviceInstaller requires the Microsoft .NET framework to be installed. If you do not have this already, it can be downloaded from: www.microsoft.com.

  Note that DeviceInstaller will not work through routers or across the Internet. All the devices need to be on the same network segment as the PC.

• Find out the MAC address of the network interface. This should be printed on a label on the case.

• Connect the 6-pin Ethernet port to the the PC's network interface either using a crossover Ethernet cable or through a network hub. Note that using a hub, you can connect several CD24s to the same PC and configure them all at the same time.

• Use the power cable to connect the 4-pin power connector to a fused 10 – 28 V power source. A 12V DC power supply is recommended.

• Run DeviceInstaller.

  DeviceInstaller's main window has two panels, a tree on the left (with Lantronix Devices at the top) and a table on the right.

• The program will automatically look for Lantronix devices on all of your computer's network interfaces. If necessary, you can narrow the selection by clicking on an entry in the tree on the left. If the program does not list the device, press F5 or use Device > Search from the menu system.

  

• A WiPort NR entry should appear in the table on the right, denoting that a device has been detected.

• If more than one WiPort NR entry appears, DeviceInstaller has detected several devices.

• For every detected device, the program shows the Hardware Address (i.e. the MAC address) and the IP address it is currently using. If you are using a wireless router with a DHCP server, or an access point connected to a network with a DHCP server, the device will use DHCP to assign it an address. Otherwise, a random address will be chosen automatically.

  Note: Automatic random addresses all begin with 169.254. The CD24 will choose a different one every time it is power cycled or rebooted.

• The address of the CD24 may be shown in red with the status Unreachable. If this happens, the sensor and PC cannot communicate because they are not on the same subnet. Click Assign IP to start the IP configuration wizard. Follow the instructions in the wizard to set the IP address, or configure DHCP if you are using a DHCP server. When you have finished, press F5 or use Device > Search from the menu system to find the sensor with its new IP address.

  Note: The IP address of the digitiser must have be on the same subnet as the computer you want to connect to. The LAN setting on the DeviceInstaller device tree identifies the IP address of your computer. The first three number groups typically need to be the same on all devices (digitisers and computer).

• If you want to configure the CD24 to use a static IP address, use the Assign IP wizard as above and click Search again.

• Double-click on the entry which corresponds to the CD24 you want to configure. The right-hand panel will change to show the current properties of the device.

  

• Switch to the Web Configuration tab and click Go to open the Web configuration interface.

  

• You can also click Use External Browser to use your own Web browser to configure the system.

• Follow the steps at section 3.2 on page 7.

4.3 Appendix C - Advanced network configuration

The Lantronix WiPort NR networking module has serial-accessible configuration systems which can be used to configure them in the event that communication over a network is lost.

If you have problems connecting to the CD24 over a network, you can access the configuration menu over a serial link by interrupting the boot process. See the following section for instructions. For full information about the WiPort NR configuration options, which are used during the process, please refer to the relevant documentation, which is available on the Lantronix Web site: www.lantronix.com. The detailed documentation is at: www.lantronix.com/pdf/WiPort-NR_UG.pdf

4.3.1 Accessing the configuration menu via the serial Interface

Access to the configuration menu over the serial interface can be obtained using any serial terminal emulator (see Appendix D on page 26).

The procedure for connecting to the device is:

• Disconnect the power supply.

• Disconnect the sensors.

• Remove the top cover from the acquisition module.

• Disconnect the 26-way IDE-connector from the digitiser as indicated in the figure below:

  

• Connect an RS232 cable between the 9-pin D-connector and a PC. See Appendix E on page 31 for connector pinouts.

• Open a terminal connection as described in Appendix D on page 26.

• Hold down the key while applying power to the acquisition module.

• After a few seconds, a banner will appear, showing the MAC address of the network interface, along with software and library version information. Press the Enter key to access the set-up menu. If you do not press a key, the system will proceed to boot normally.

4.3.2 Configuring the network interfaces

Once you have access to the networking module's configuration menu, you can configure it with its proper settings.

During the configuration process, you are prompted, in turn, for every value in the current section. If you are unsure at any point, pressing the Enter key will retain the current value. Please note that many values need to be entered using special codes. These are all documented in the relevant Lantronix manuals.

From the main menu:

• Each channel is configured individually. To configure either press 1 (Channel 1) or 2 (Channel 2).

• Set the Baud Rate to 115200. This is the default baud rate for the CD24's digital output.

• The remaining settings can be left at their default values, which is done by pressing Enter at each prompt until you are returned to the main menu.

• When you have finished setting up the module, apply the new settings by selecting option 9 Save and Exit. The module will re-boot with the new settings in effect.

4.3.3 Configuring the Ethernet port

To configure the Ethernet port

• If DHCP is not being used to assign IP addresses, enter the required address manually. The IP address must be set to a unique value in the network. Enter each octet and press Enter to move to the next octet.. The current value is displayed in parentheses. If you do wish to use DHCP, enter 0 at each prompt (an IP address of 0.0.0.0 is used to select DHCP operation).

  

• If the digitiser is to be connected to a routed network, enter the address of the default gateway in the same manner.

• At the netmask prompt, enter 0 if you are using normal (classful) internet addressing. If you have a non-standard or classless addressing scheme, enter the number of bits of the IP address to be used for network identification. Note that this is not the standard way of specifying netmasks; it is more akin to the /n modifier used in CIDR address specification.

• When you have finished setting up the module, apply the new settings by selecting option 9 Save and Exit. The module will re-boot with the new settings in effect.

• Disconnect the power supply from the acquisition module.

• Remove the RS232 cable from the 9-pin D-connector.

• Connect the 26-way IDE-connector to the digitiser.

• Install the top cover.

• Connect the sensors to the acquisition module.

• Connect the power supply to the acquisition module.

4.4 Appendix D - Using terminal emulators

There are a number of terminal emulator programs that you can use to access the serial ports of the digitiser and networking interfaces. Three of these are detailed below.

4.4.1 Hyperterminal, as provided with Windows XP.

• Click on Start and then Run.

• Enter 'hypertrm' and click on OK.

  

• The program will ask you for a name for the connection:

  

  Enter any suitable name, then click OK.

• You will then be prompted to enter COM port and modem details:

  

  The Country/region, Area code and Phone number fields can be ignored: they are only used when working with modem connections. Select the name of the correct COM port from the Connect using drop-down menu, then click OK.

• Enter the port configuration settings:

  

  Ensure the following parameters are set:

  Bits per second: 9600

  Data bits: 8

  Parity: None

  Stop bits: 1

• Click on OK and the program will then connect provide you with a terminal emulator screen, from which you can access the command line of your system.

4.4.2 Using Hyperterminal with Windows Vista or Windows 7.

HyperTerminal is not provided with the Windows Vista or Windows 7 operating systems but the necessary files can be copied from the i386 directory of the Windows XP CD if you have one available. The two files you will need are:

hypertrm.dll

hypertrm.exe.

If you do not have a Windows XP disc the files can be downloaded from: www.mediafire.com

To use Hyperterminal with Windows Vista or Windows 7:

• Copy the two files into your windows/system32 directory.

• To access HyperTerminal, use Windows+R on your keyboard. Enter 'hypertrm' and click on OK.

• If Windows open a security warning window click on Run. You may also be asked if you wish to use HyperTerminal as a the default terminal window.

• Now follow the instructions given in section 4.4.1, above.

4.4.3 Using PuTTY.

PuTTY is a free terminal package for windows which is useful if HyperTerminal is not available. It can be downloaded from www.chiark.greenend.org.uk. The easiest package to use is the 'windows installer'. Install PuTTY by following the on-screen instructions.

• Start PuTTY by clicking on the desktop icon or Start-menu entry

• Click on Serial at the bottom of the category menu on the left:

  

• Select a serial line to connect to. This is usually COM1.

• Configure the serial line with the following settings:

  Speed (baud): 9600

  Data bits: 8

  Stop bits: 1

  Parity: None

  Flow control: None

• Click on Session in the main menu on the left.

• In the right hand part of the window use the radio buttons to select the Serial Connection type. Check the Serial line and Speed fields are correct:

  

• To save the settings enter a suitable session name in the Saved Sessions field then click Save.

  The next time you start PuTTY, your saved session will appear in the list and you can simply double-click it to open a new session with the same settings.

• Click the Open button to start the terminal emulator.
