Overview

Firmware protection by a password helps prevent unwanted access to the module firmware.

Password

The password is case-sensitive and contains 8 to 16 alphanumeric characters. The password robustness is increased when it contains a mix of upper and lower case, alphabetical, numerical, and special characters.

NOTE: When importing a ZEF file, the firmware password is stored inside the module only if the File encryption option is selected.

Changing the Password

It is possible to change a password at any time.

NOTE: Firmware password default value in the Control Expert application is: fwdownload.

  • For firmware V4.01 and later, you need to change the firmware password default value, otherwise it will not be possible to build the Control Expert application.

  • For firmware versions earlier than V4.01 it is not mandatory but strongly advised to change firmware password default value.
