Reprogramming MR430 Firmware
Over time as the firmware functionality is expanded, it may become necessary to reprogram the
firmware. The firmware resides in permanent flash memory which can be re-programmed with the
appropriate software.
Download from the Micronor web site:
-FLASH_MR430.zip
Extract the *.msi file and install this software on your PC.
Request from Micronor or the authorized Service representative the new Firmware:
-MR430-1_V1pxpxx.hex (for DIN Rail version)
Setup the MR430-1 as
shown to the left.
Connect the USB cable to
the PC.
Power the unit with a
suitable 24V DC supply.
Prepare a paper clip or a
small pin able to reach the
Home/Reset button on the
MR430-1 unit.

After starting he software define
the Virtual Com Port (VCP) that
the PC assigns when the USB is
connected.
Select the firmware hex-file that
previously was stored on your
PCB.
The software validates the
integrity of the hex file.
Caution: Make sure it is the hex-
file provided to you by Micronor.
It is possible to flash any valid
hex-file. However at that point
the MR430-1 unit will no longer
be functional and may have
caused internal damage.
Click Start.
If connection to the MR430-1
unit has been successfully
established, then the software
prompts to push & hold the
Home/Reset button on the
MR430-1 unit. Push the button
and hold until the “Release
Button” prompts you to release
the button.
