Adding a COM port

Posted on 2014-01-13

I have a Dell Optiplex 3010 with Windows 7 Pro. We purchased a PS2 serial port adapter (low profile) and I installed it but I do not see any evidence that it has been successfully installed and I do see an additional port installed. How do I get this device installed and an additional COM port activated?

Thank you!

Robert

You should install the drivers provided with the adapter or, even better, download the most recent drivers from adapter's producer web site.
When installing the drivers be careful to choose the correct architecture (x86 or x64).

This is a Dell adapter that did not have any drivers included and I cannot find drivers on the Dell web site.

Please post the model of the adapter.
Each device has a driver (even the keyboard and the mouse). Sometimes the driver is already included in the OS and other times must be added "manually".

I don't see a serial #. The Manufacturer's part # is G257D and the Dell part # is 310-6685.

I understood that was an add-on cad. It is just what you exactly described: an adapter.
I consider (obviously) that you connected the cable to the correct plug on your MOBO.
That said, you should get in the BIOS and enable the serial port (also known as RS-232).

can you see the adapter, or com port in device manager?
if not, it may just be bad
the fact it does not need a driver, is because it uses a generic one from windows

You do not need any additional drivers, otherwise would have been supplied with the hardware.
Just check in the Device Manager the serial ports (COM) number.

In the BIOS the serial port options show COM 1 enabled. I can right click the ports in Device manager and add a port but I get the Yellow Triangle indicating an error.
This is the second of these cards that I have tried thinking that the first one might be bad.

The Yellow Triangle reports one or more resource conflict(s). Please check the details of the device (right-click the device on device manager).

Sounds like you might have to Disable the Onboard Com in the BIOS, or set the Addin Com to Com2/3/4.

What I understood is that the adapter is simply an "extender" of an existing COM port available on board.
The requester could change the COM port (from 1 to 2) directly from the BIOS. This change could fix the Yellow Triangle.

No, it connects to the motherboard via a data cable.

This card is connected to the motherboard via the KBMSCOM1 connection. This is the second card I have used and I don't see anywhere in the Device manager where this card has been installed. I have updated the BIOS and I have tried different COM port settings in the BIOS. So far - no luck.

So is the same as in the photos from here:
http://accessories.dell.com/sna/products/Cables_Hubs_Adapters/productdetail.aspx?c=ca&l=en&s=bsd&cs=cabsdt1&sku=310-6686&~lt=popup&~ck=TopSellers

http://accessories.us.dell.com/sna/productdetail.aspx?sku=310-6685&cs=19&c=us&l=en

Did you consider a problem on motherboard? Did you connect it in the right place, or maybe a setting jumper?

did you check in the bios that that port is enabled, and also serial ports?

Did you try changing the COM port in the BIOS from it's default value (might be COM1) to another value (such as COM2)?

What is your PC model, motherboard type? MT DT or SFF?
http://www.dell.com/downloads/global/products/optix/en/optiplex_3010_technical_guidebook.pdf

Here you find the manual of each type as pdf file:
http://www.dell.com/support/Manuals/cn/zh/cnbsd1/Product/optiplex-3010?c=cs&s=bsd&l=en

After you download the pdf for your type, search inside the pdf for "Serial" and tells you how you can enable it.

The port itself, the integrated circuit which does the communication RS232 is implemented direct on motherboard.
What you purchesd seems only a simple adapter with cables and connectors:
http://accessories.dell.com/sna/products/Cables_Hubs_Adapters/productdetail.aspx?c=ca&l=en&s=bsd&cs=cabsdt1&sku=310-6686&~lt=popup&~ck=TopSellers

http://accessories.us.dell.com/sna/productdetail.aspx?sku=310-6685&cs=19&c=us&l=en

If it is like that, means that you should be able to see in the Device Manager and enable from BIOS the Serial Port, even without your adapter.
