Troubleshooting: AvaLAN Wireless Communication

Kiran

Symptoms:

General communication issues 

 

Environment:

Dispensers with SU's connected through AvaLAN Wireless AO

  • Equipment DFS58EMVAP and DFS584EMVSU
  • Wireless AP connected site

Resolution:

  1. Validate that all SU and APs are paired properly
  2. Validate that the appropriate status lights are active on the SU and the AP after paired
    1. RF Link (Mostly Solid, not a steady blink)
    2. RF Transmit and Receive
    3. Network Activity (Ethernet Active)
    4. Validate that the SU is showing higher than Signal Low, or if Signal Low is blinking
  3. Perform ping test between laptop and Jade or Anthem board.
    1. Plug in-store POE to laptop and set laptop network port IP address appropriately on the same IP scheme as
      the dispenser Jade Board Example: If the Jade Board IP is 172.29.1.101, set the laptop as 172.29.1.50
    2. Perform ping test and note large “Time” values, as those should be below 50 milliseconds and you should not
      have ANY “Time Outs”
  4. Adjust AP location so that AP is closer to the forecourt and or has less blockage (walls, etc.) from the AP to the
    forecourt

Advanced options:

Enter Site Survey Mode:

Site Survey Mode

  1. When an Access Point is silent, an In-Dispenser Pairing Key can be inserted into the Access Point to enter Troubleshooting / Site Survey Mode. This mode starts 45 seconds after the key is inserted. To exit this mode remove the key. In this mode the:
    1. The Access Point will begin to beep how many Radios are connected. The beep pattern is two slow beeps followed by faster beeps. The number of fast beeps is the number of actively connected In- Dispenser radios.
    2. The In-Dispenser Radios will chirp their signal strength with lower signal indicated with slower beep rate and higher signal with faster rate. The radio operates well even when the rate is slower. Expect the rate to be a little slower with the door closed. The beeps begin 10s after the key is inserted in the Access Point and will stop 30s after the key is removed. The beep pattern becomes a warning siren if the signal is too high indicating that the radios are too close (<10ft). Also, the LEDs behavior changes so that all 6 LEDs (rather than 3) display the signal level. This can provide a more accurate meter for comparing signal levels assuming the LEDs are visible.
