cRIO configuration issue- serial connection to laptop

[legend]

Are you using a regular serial connection or a USB to serial converter? I have seen a similar problem in PCs that do not have the serial connection.

If I recall correctly, you must use a null modem cable between your computer and the cRIO instead of a standard serial cable. It's just like making a serial connection between two normal computers.

Yeah, we got a null modem cable. That's why we're so surprised it's not working. We've also checked all the settings many times to make sure the connection's set up right: 9600,8,1,none,none, and the right com port. Any other common errors?

Can you confirm that the serial port on the computer is not broken?

Try to connect to the cRIO with a different computer with hyperterminal

We plugged in our null modem to the cRIO, ran Hyperterm on the PC with COM1: 9600,8,n,n as you suggest with the console dipswitch set to ON and it worked first time. Ensure your serial port is enabled in the BIOS, enabled in Device Manager and no one has tinkered with the IRQ's etc.

I would also recommend testing with another PC.
