Apologies, I am trying to connect via USB and I have already identified which COM port it is.
If the UDL is changed, then upon connection it complains that it is incorrect (further confirming that communication takes place).
Having tried using the account with all zoned configured to connect with no success, I decided to restart from scratch with the most basic default settings, as described in the manual, specifying no information other than the COM port and account ref.
The message I keep facing is "Connection with Control Panel could not be established - Please check settings and try again!"
This appears shortly after "Status: Requesting access with panel..."
