For security reasons / standards:

- Change the default password.
If the user utilises CloudLink in addition to the EC350, CloudLink must also be running the secure
firmware.
6.3.5 Updating EC350 firmware
EC350 is provided with a built-in firmware loader that allows new versions of firmware to be installed
easily. Firmware can be upgraded using the Firmware Upgrader option available in the MasterLink
Software Application SQL software. When you select this option, the MasterLink Software Application SQL
software works with the built-in loader of EC350 and provides a very robust system for upgrading the
EC350 firmware.
The firmware upgrade is performed through the IrDA serial interface that is used by the MasterLink
Software Application SQL software. The IrDA serial interface provides an electrically isolated interface and
requires no additional hardware or software beyond what is already needed to utilize the MasterLink
Software Application SQL software. (Firmware upgrades can also be performed over the RS-232 port but
not the RS-485 port.)
The following firmware upgrades should be performed in order when switching from non secure to secure
firmware:
-Application Firmware
-Key File
-Boot Loader.
Caution:
It is important that you read all items and logs (audit trail logs, event log, alarm log) before performing
a firmware upgrade because most items will be set to default values and the audit trail logs will be
erased.
Note:
-Secure firmware version number starts with 1.7xxx.
-After upgrading to secure firmware version 1.70 or higher, a device cannot be downgraded to a
firmware version below 1.70.
