If you have forgotten the security settings, and need to reset them, you can do so as long as you are on site….
This will reset all security settings, but will not affect the config at all…YAY!
Start the terminal program on your PC. Ensure that it has been setup as listed in DTE Port Settings.
Once connected, enter AT (note, it is upper case)
Then enter, AT-SECURITYRESETALL
You will be prompted to confirm the control units MAC address before continuing. Enter teh MAC address.
After approximately a minute, the control unit will respond with an OK when the action has been completed.
Close terminal, and open manager. You can now use manager to connect and reset the security settings…
