Lantronix WiPort Setup for Surveyor SRV-1


Hardware Setup

  • If you are installing your own WiPort on the SRV-1 WiFi circuit board, *carefully* align the tabs of the WiPort with the slots on the circuit board and press the WiPort into place. You can bend some of the retaining tabs to securely hold the WiPort module.





  • Make certain that SRV-1 robot power is OFF. Remove the Zigbee radio from the SRV-1. Remove the 2 small screws holding the SRV-1 controller to the robot base. Install the two 1" hex spacers in place of the two screws. Plug the 10-pin connector from the SRV-1 WiFi board into the Zigbee radio header on the SRV-1 controller. Make certain that the connectors line up.



  • Solder the red power wire from the SRV-1 WiFi board to the BATT pad on the SRV-1 controller. Make certain to make a good solder connection.



  • Secure the SRV-1 WiFi circuit board to the 1" hex spacers using the screws you previously removed from the SRV-1 controller board.



  • You're finished. At this point, you can turn on the SRV-1 power, and the red LED on the SRV-1 should light up. If it doesn't, check your connections. If it still doesn't, contact Surveyor Tech Support.




Software Setup

  • Update your SRV-1 firmware. If your SRV-1 has an RS232 port, it will be easier to install the firmware that way, as shown here - http://www.surveyor.com/SRV_setup.html#setup3. Alternatively, use your existing Zigbee radio to update the firmware.



  • Turn on the SRV-1 robot so that the WiPort is powered. Start your wireless network manager program, and connect to the SRV1 adhoc network (if we didn't configure the WiPort, it might instead be the LTRX_IBSS adhoc network).



  • You should now be able to connect to the WiPort via your browser. We have configured the WiPort modules by default to IP address 169.254.0.10, so point to http://169.254.0.10. There are no passwords set, so just hit 'enter' if you get a message asking for passwords.



  • If we configured the WiPort, then the serial port should already be configured correctly for 921600kbps with hardware flow control.



  • Now edit srv.config in the SRV1Console directory. Add a network entry that has the IP address of your WiPort module.



  • At this point, you should be able to connect to the SRV-1 using SRV1Console and the WiPort.



  • The final steps are to configure the WiPort to your infrastructure network instead of just connecting via the adhoc network. If you aren't familiar with WiFi network configuration, ask for some help. If you use the wrong settings, the WiPort won't be reachable, and you will physically have to remove it from the robot to reprogram via the alternative setup below.

    Make certain that you know the SSID of the wireless network you plan to use, and also make certain to find a free IP address, as you need to configure the WiPort with a static IP (or you won't know how to reach it).

    First change the WLAN settings from the SRV1 adhoc network to your infrastructure network -





    Next change the IP address from the adhoc IP 169.254.0.10 to the IP address of your network -





    Click on Apply Settings. If you've done this correctly, the SRV1 network will disappear and your host computer will connect to the infrastructure WLAN. From here, confirm that you can reach the robot WiPort via your browser at the new IP address, then edit srv.config to set the new IP address of the robot, and try to connect via SRV1Console.





Disaster Recovery

If the above-described software configuration doesn't work, and you are unable to access the WiPort module after configuration, or if prefer to directly connect to the WiPort through a USB serial port to reset factory defaults, follow these steps:
  • Locate the small USB board that is included with the WiPort expansion card -



  • If you haven't previously used the SRV-1 robot with the Zigbee radio, install the "SRV-1 base station radio USB drivers" from http://www.surveyor.com/srvdownload/

  • Note the 10 pin header on one side of the USB board, and the single header pin next to "C2" above the red LED -



  • Plug the 10 pin connector into the USB board, but leave the red power wire disconnected -



  • Start your favorite terminal program using the serial port that has been assigned to the USB interface. We really like the Bray Terminal program for Windows, which you can now download from http://www.surveyor.com/srvdownload/termv19b.zip

    In any case, set the serial port to 9600 baud, 8 bit, no parity, 1 stop bit, no hardware flow control, connect to the serial port, and held down the 'x' key -



  • Finally, while holding down the 'x' key, plug the red wire from the WiPort expansion card into the C2 header pin to power the WiPort board (this can take some coordination) -



  • The WiPort configuration monitor should come up almost immediately. Because the WiPort is powered, you can modify the configuration and then test the coniguration by connecting to the radio via your browser (don't forget to connect the WiPort antenna first) -
