Click the play button to run a test. A green checkmark will appear if the test passes, while a red X will appear if the test fails. 

Note: When performing loopback tests, it is recommended to disconnect any cable/harnessing to external equipment.

• 485 Loopback Test – Wire Sign Port A to Sign Port B and then run the test. 
• 485 Port A/B Internal Loopback – These tests check internal function of the transceivers (unnecessary if the 485 Loopback Test passes). 
• 232 Port Loopback – Short pins 2 and 3 on the POINT OF SALE jack, and then run the test to check RS-232 operation. 
• Run Test Pattern 
  • None – Return to default operation. 
  • All Off – Blank the displays. 
  • Linear Addresses – View the addressing of each module within the entire system. 
  • Node Addresses – View the addressing of each module within its display. 
  • Module Permissions – View the hierarchy of display control. Each module will display G (Grandparent), P (Parent), or C (Child). 
  • Display Borders – Show a line around modules that are configured as “displays”. 
  • Product ID – View the content type (Price or Message) assigned to each display. • Firmware Version – View current software version installed on each module.

Indicator lights: 

• When everything is operating normally, the STATUS LED will show a regular slow blink with equal on and off times. If any other pattern is displayed, check the software user interface for further information.
• The POWER LED should be ON steady. If not, check the power connection. 
• The RUN LED blinks with processor activity. If ON steady or always off, there is a problem. 

⚠️Unable to connect to user interface web page.

• Verify POWER LED is ON. If not, check power connection.
• Verify STATUS LED is blinking. If not, cycle power, wait ~1 minute to reboot and attempt to connect again.
• Wired network connection – verify LEDs are lit on the NETWORK jack. Check network cable connections and customer network equipment.
• Wi-Fi connection – Refer to Connecting to Software (above) to connect directly to the “Fuelink 5” access point and verify customer Wi-Fi network settings.

⚠️Unable to find any radios. 

• Verify radios have power (PWR LED is lit up).
• Verify all radios are set to the same Network ID and channel. Refer to Wireless Communication to Display-Fuelink 5: How do I install and connect to the controller?.

⚠️Prices are not updating, or only update intermittently.

• Make a manual price change as described in Fuelink 5: How do I configure products and prices for my display, and watch the status window at the bottom of the page.
• The messages in the status window will indicate where the price change is failing. Use this information to determine where to look for communication problems.
• Problems that can be detected automatically will be indicated in the System page by a red triangle. If manual price changes do work, there may be a problem with the POS interface itself or the connection to it. Refer to the issue below.

⚠️POS interface not working, but price can be changed manually.

• Go to Diagnostics > POS Monitor to verify data received when a price change is initiated on the POS. 
• POS price change problems can be caused by physical connection issues or incorrect POS settings. Refer to the Fuelink 5 POS Interface Guide (DD5403695).

⚠️Price display is blank. 

• Verify proper power to the display. Refer to the Daktronics FL-5000 Series Display Installation & Service Manual (DD5042067). 
• Verify an All Off test pattern is not running. Refer to Run Tests in the section above. 

⚠️Price display is partially blank.

• There are status LEDs built into each display module to help troubleshoot display problems. Refer to the Daktronics FL-5000 Series Display Installation & Service Manual (DD5042067).

⚠️Price format is incorrect.

• Refer to Configure Displays Fuelink 5: How do I detect displays and format my display

⚠️Font is incorrect 

• Refer to Configure Displays Fuelink 5: How do I detect displays and format my display.

⚠️Display is garbled or looks odd in any way

• Refer to Configure Products/Prices Fuelink 5: How do I configure products and prices for my display to select the proper content for each display.
• Displays ship from the factory preconfigured, but if modules are replaced or moved around within the display, reconfiguration is required. Fuelink 5: How do I detect displays and format my display

⚠️Display is unexpectedly switching between prices
