4.5.2 Reset the Security Key in the SEG to all 0's
NOTE: This requires SEG firmware v1.30 or higher.
This feature is provided to allow you to reset the Security Key in the SEG back to all 0's, which is the default out-of-box state.
Resetting the Security Key in the SEG would be required if you are replacing a SEG with a previously used SEG that already has a
Security Key set into it and you don't know what the Security Key is, or if you are setting up a new site and want to communicate with
an existing SEG that is already installed and already has a Security Key set. NOTE: This feature can only be used with SEG devices
with v1.30 or greater firmware.
1. Go to the SEG and either cycle power to it or press the little black reset button on the SEG.
2. Within 10 minutes, go back to the PC and select the button in the Site Edit screen that is labeled 'Reset the Security Key in
the SEG to all 0's'.
3. You will see a warning message specifying the requirements of using this feature. If you have met all the requirements then
press the OK button.
4. If the Key was reset properly then you will see a confirmation message (Fig. 8).
5. As a security measure, you must now go back to the SEG and once again cycle power or press the reset button on the SEG.
This will set the new Security Key into non-volatile memory. Failure to reset the SEG after the Security Key is reset using
this method will result in not being able to communicate with the SEG.
6. Reset Complete. The Security Key has now been reset to all 0's in both the SEG and PC. Communications with this SEG
should now be possible.
4.5.3 Reset the Security Key in the PC to all 0's
This feature is typically used if you have replaced an existing SEG with a new SEG or a SEG that has a Security of all 0's.
NOTE: If you use this feature and the SEG does not have a Security Key of all 0's then you will have to set the Security Key back to
all 0's also.
