Firmware history
NB: user guide and Datasheet will always be updated accordingly to the latest active firmware version
May 2025 : 1047 Firmware update#
- Modbus configuration of parity available
- Unique internal serial number for identification of each NextPM with a command
Simplified protocol optimization:#
- Possibility to activate or deactivate the heating system with simplified protocol
- Total Suspended Particles (TSP) available
- 5 channels available
