14.3 Updating the Lock Firmware
There exist two separate files that the M-Unit can upload to the lock. One is the “bootloader” and the other is the
lock “firmware” itself. The bootloader is a separate small program that is invoked to replace the E-Plex 5900
firmware file in the lock. The normal procedure is to first replace the bootloader, and then the firmware file.
However, if the operator knows that there is no change to the bootloader, it is perfectly acceptable to simply
update the firmware file using the existing bootloader.
Important:
In order to perform a firmware upload the lock must be placed under control of the bootloader. This
means that after starting communication, the lock will beep and shut down for a few seconds. You must not move
the M-Unit away from the lock during this period. After approximately two seconds the M-Unit will begin
communicating again with the lock, and will proceed to upload the new firmware file. On completion of this transfer,
the lock will reboot and activate the new firmware.
