LINK Firmware Update


Current Version Date
v1.8.151 March 9, 2021

The 'v1.8.151' firmware updates from 'v1.8.150' firmware:

  • Improved consistency of HSS trigger delay. End result is more consistent picture to picture timing, reducing the possibility of banding.
  • Stopped decoding RF data on channels outside of the CyberSync range.
    Prior to this, if the LINK saw data on a channel greater than 16, it would stop functioning normally and flash the back panel LEDs.
  • Decreased sensitivity of the temperature monitors to filter out under-temperature false alarms.

Do I need an update? How do I know which version I have?
When your LINK flash unit is connected to the app, you are able to view it's current firmware version in the 'flash card' for that particular unit. If you can’t find it, call us and we’ll help determine your version.
