Hello Gaminn,
What is the name and the version number of the software that you are using?
Please take a screen capture of the connection assistant with all your settings in tact and attach it to this support thread?
What exactly are you trying to accomplish?
If you are using P&E ICS interface and are able to 'modify RAM' after RS232 interface is disconnected then
the chances are that you are working in the In Circuit Simulation Mode.
Unless you have access to the .s19 file that is programmed into FLASH or if the device is blank, you have to choose Ignore Security every time you want to connect to the chip.
If you in fact have access to the .s19 file, you should specify it in User security setting and then P&E software will automatically calculate the security code required to gain access to the on chip 908QT1 resources.
Best Regards,
Zahar
