We are pleased to announce the public release of PMU software version 122.3. This update includes multiple new features compared to the previous official version 101.2.1.

**New features:**

- CANbus Export: Added a new “Conditional” transmit mode
- Added support for up to two third-party keyboards (e.g., GrayHill, RaceGrade, LifeRacing) – previously, only one third-party keyboard was allowed
- Added a .DBC exporter for CANbus Message Objects and CANbus Export
- CANbus Export: Added a “Checksum” module, allowing custom checksum formulas for exported frames (see the separate How-to guide for details)
- Project Tree: Added a new “Rate of Change” operation for the Number element, calculating the derivative of a given channel
- CANbus Keyboards: Added a “Master Brightness Channel” option, enabling brightness control via any channel within the 0–100% range
- CANbus Keyboards: Added support for the “RacePad” keyboard (see the separate How-to guide for details)
- CANbus Keyboards: Added support for the Ecumaster “6x1” keyboard
- Units and decimal places of user-defined elements are now visible in Data Master (requires Data Master 2025.4 or newer)
- Project Tree: Added a “Change View” button to the toolbar
- Added an option to automatically synchronize the RTC time when the device is connected to the PC
- Autosaved channels can now be saved immediately when triggered by the rising or falling edge of a selected “Force Save Channel” (see the separate How-to guide for details)
- New channels: “pmu.serialNumber.A/B/C” and “pmu.firmwareVersion”
- New CANbus Input data type: float – the PMU can now read 32-bit float values from the CAN bus
- Device serial number is now displayed in the Graph Log

Is there anyway to sync the RTC with the GPS date/time?
