Pro 2 Release: ChronOS Version

We’ve Released ChronOS version for the Pro 2. Enhancements and Defect Fixes in this release include:

  • Enhancements to the performance to address reports of the controller “lagging” or locking up.
  • A fix for a defect that would cause tag reads within a few seconds of a manual marker to be included in the wrong session.
  • Added tenths, hundredths and thousandths of a second to the Gun Start Time Display and Last Marker Time display for improved accuracy.

  • Added support for keyed tags.
    • To access this functionality:
    • Go to Race Ops => Marker and Tag => Keyed Reads

    • Keyed Reads can be entered using a USB keyboard or the keypad on the Pro 2.
  • Added colors to battery status for easier visibility to battery levels.


This new version is available in the downloads area of the Timer’s Portal.
