Make sure you have installed necessary software for the device to get detected in the system.

Install NI-VISA driver if it is not done yet. Could you show what you see under the "Software" entry in MAX (open it)? If VISA is missing, you should install it.

 

Edit: Your RS232 port a native one in your PC, or you use a RS232-USB adapter? If so, you need to install its device driver also. Be aware that some USB-RS232 do not play nice due to low quality chipset, but usually an FTDI one is a good choice...
