I opted for DOS:
tftp -i xxx.xxx.xxx.xxx PUT Web1.cob WEB1
which worked. In fact I can now see the Menu on the side.
I enter the engineering password. When I click Online Keypad, I get the keypad indicating "Reading.......", then I get no "Access with System". Then I click something else such as System Zone Status or Event Log and I get a System Alerts on the keypad - Areas need reset and Com 1 Fault. Trid this a number of times and always get the same issue.
Do I need to enable something?
