The current versions of PM4 Firmware are as follows:
- Indoor rowers—The version you need depends on the age of your PM4, although the functionality is the same in each case. More info
Versions 29 and lower are for monitors with the original microprocessor, which was discontinued by the manufacturer. In order to use a different microprocessor, we needed to redesign the PM4. The redesign did not alter functionality between PM4s using different microprocessors but did require a new firmware version.
The first PM4s to use the new microprocessor were put into circulation in June of 2008. These PM4s were released with PM4 Firmware Version 304. If your PM4 Firmware Version is 304 or higher, then PM4 Firmware Version 332 is the current version for your monitor. Otherwise, PM4 Firmware Version 29 is the current version for your monitor. The firmware versions are not interchangeable. That is, Firmware Version 303–332 will not work on a PM4 with Firmware Version 29 and lower, and vice versa.
- Version 332 (released July 2018)
- Version 29 (released November 2012)
- SkiErgs—Version 732 (released July 2018)
Current firmware releases resolve many of the issues identified in earlier firmware versions. If you are not running the most current firmware, we recommend updating your monitor.
