What has been improved

The following are a few of the improvements that have been made to new control board:

  • Mobile app support
  • Improved support for third party products
  • Improved LED driver efficiency
  • Improved reverse battery connection protection
  • Faster boot-up procedure
  • Lower power consumption
  • Improved date/time backup to >24hrs when power has been removed—removed replaceable battery coin cells in favor of a capacitor bank
  • Improved interface to radar to support two-way communication via SpeedCheck Manager
  • Removed legacy hardware and replaced with software configuration via SpeedCheck Manager mobile
  • Increased storage capacity for data logging
  • Improved labeling on the circuit board
  • 10-pin serial connector is now keyed and latching
  • Added LED display board nightly test for third party remote monitoring

With the removal of the coin cell batteries from the previous controller revision, you will now have >24hrs of built-in backup power with the power removed from the system before the date and time will have to be updated via the SpeedCheck Manager mobile app. If you are using this board for legacy systems (2010 Q1 or older) that contain the original LED display boards, you will need to enable 20mA intensity mode via SpeedCheck Manager (otherwise the LEDs will appear significantly dimmer). You may also refer to this article here regarding changing the LED display board intensity.
