Hi just purchased a new ASUS Zenbook UX31E and after having installed some monitoring software for my solar panels I installed the USB driver for my 232 to USB cable. When trying to set the COM Port for this I found the Ports (COM & LPT) were not desplayed in the Device Manager. I tried showing hidden devices to no avail?

Any advice would be helpful thanks.

What operating system is on the Zenbook? I find it odd you needed a special driver - it seems Windows 7 should have it.

Did you reboot after installing?

And this USB to RS232 cable setup worked fine before on another computer?

Did you try a different USB port?

Yes it worked fine on another ASUS I am replacing running Windows 7 HP.

I haven't plugged the USB in as yet as I need to configure it to run on COM Port 1 for the monitoring software to work.

I just expected the various COM ports to be displayed in Device Manager as they have been on most other computers or laptops I have used?

Since COM ports are legacy devices, many new motherboards/computers don't have them - thus the need for an adapter, like your RS232 to USB cable.

What does your manual (or the cable's website installation instructions) say? In looking at a few cables, they all say with Vista or Windows 7, make sure nothing is connected to the RS232 connector, then plug the USB end to the computer. Windows 7 should see it, and install the proper driver for you. Then you should see it in Device Manager. And from there, you can follow the instructions to install the RS232 device.

Thank you for that I will try in the morning when the solar system wakes up (it's 10:55pm here now).

The manual refer's to win7 etc and as the whole set up works fine on my other ASUS UL30VT I certainly didn't expect it to be an issue with the new UX31E.

Let's hope by plugging it in it recognises it but I have a feeling it's going to come up with something like no COM port 1 or ....

Thank you for your help and I will report back tomorrow.

Sounds like a plan but do note, from what I am reading, it is important to connect just the cable to the computer first - that is make sure the RS232 end has nothing attached.

Digerati problem solved. As soon as I plugged the 232/USB cable in it picked up the driver I previously loaded and allowed me to configure the necessary COM Port for the monitoring software. Ports now show up in the Device Manager.

Many thanks for your help and YESSSS Geeks to Go does it again.

Cheers
