Dell 36500 Docking Station

You can't use a cable to convert DVI-D (which is digital only) to VGA (which is analog).  You'll need a converter box.

If what you're converting is DVI-I to VGA, that CAN be done with a simple adapter:

Here is what I have.

After looking at it, it doesn't say anything about DVI-D so I have to assume that it is just a DVI connector.  However, the D-Link Cable I had didn't work.  I think it had a total of 9 pins.  Also, the connector on the docking station does not have the 4 pins that surround the tab (far right of connector).  The only other cables available at the stores I went to had the 4 pins.

Is the connector just a standard one or is it a DVI-I?

Thank you for your help.

Those look like DVI-D dual-link.  They're digital-only - if you don't have a monitor with a digital input, you're going to have to use a converter box.
