I know this may be basic but I am learning. I was wondering if I could get a sample of code for password protecting (just 4 digits) one of the screens on a pv600 that has the old firmware (no screen security setup). This site has been a great help to me. Thanks ahead of time. Paul

You can use the combination of input value = stored password then move screen number to screen control tag. However, it is possible to update the firmware to include the security options. We have done both.
