Over the life of the UD-ULTCDL docking station there has been one substantive change to the product design. This change affected the types of video outputs available, the amount of USB-C Power Delivery the dock can provide to a host computer, and the peripheral port selection. As a result, there are two different versions of the UD-ULTCDL.
You can identify which version of the UD-ULTCDL docking station you have by checking the video output ports on the back of the dock. If the rear panel features one white DVI port and two HDMI ports, you have the original Version 1 dock. If it features three HDMI ports and an SD card reader, you have the current Version 2 dock. Full details of the port layout of each version can be seen below
