All PocketWizard radios with a USB port can be easily updated to the latest firmware using the PocketWizard Utility. All PocketWizard radios in your system should be using the same firmware version for proper functionality. Newer firmware may not be compatible with older versions in some cases.
The PocketWizard Utility also enables you to configure your settings in the ControlTL firmware found on the MiniTT1 and FlexTT5 radios.
