Two separate Fuelight displays change prices simultaneously, Drivers set to same address.

Potential Symptoms

  • New gas station across the street or nearby gas price station that also uses Daktronics displays with an FLR-100/RC-50.
  • Fuel price changes by itself randomly throughout the day.
  • Price changes at both stations or 2 separate pylons with digits have a price that change at the same time.
  • Handheld changing prices on another sign at another store.
  • Price jumps on one digit of gas price display on its own with no one using the key fob.
  • Display currently working and price will always update when change is made.

Environment

  • Product Family: Digit and Price Displays 
  • Products: FL-2000, FL-2100, FL-2300, FL-4000, DF-2000, DF-2009, DF-2100, DF-2300, DF-4000, Fuelight or DataMaster, Gas Price or Petroleum Displays, FL or DF digit product
  • Components
  • Control System: FLR-100/RC-50 handheld (wireless key fob)

Cause

  • The dip switches on the FLR-100's and drivers are set to the same unique addressing at both store locations, and the stores/pylons are within radio range of each other.

Resolution

  1. Set the address on the FLR-100 handheld and the address on the driver in the display to the same address.
  2. To do this, first verify the driver part number. The part number is located on the driver inside the display.
  3. If you are having issues deciphering which way the switches need to go, follow these steps.
    1. Set the dip switches on the back of the FLR-100 all one direction.
    2. Set the dip switches on the driver with the RC-50 radio connection to all one direction and test communication.
    3. If it fails, set the dip switches on the driver all the other direction and test communication.
    4. Once communication is established, change 1 or more dip switches on both to set a unique channel, if desired. This would be required if another gas station price sign is close by and using the same system. Cross talk could occur if both were set to the same unique address.
