Files\TTERMPRO and click Save.
NOTE
Use Tera Term Pro to view the current controller configuration settings.
Write down the current settings. You will need to restore these settings
when you complete the firmware upgrade (see “Restoring the Controller’s
Configuration Settings” on page 16).
FIRMWARE VERSION 3.0 INSTALLATION
Once you set up the PC and Tera Term pro, you are ready to install the CK721-A Version 3.0
firmware.
IMPORTANT
If the firmware upgrade fails, the CK721-A controller will not be
operational until the firmware can be successfully installed. This poses a
high security risk to the building and its occupants. Before proceeding,
discuss the potential security issue with the building’s Security Manager.
NOTE
Configuring the PC takes approximately 2 minutes and must only be
performed once. Once the PC has been properly configured, installing the
CK721-A firmware takes approximately 15 minutes per controller.
