These are pictures of the si-tech wired  handpad. There is a "phone type" wire and a RJ connector that plugs directly into the controller. The buttons do glow in the dark.

This is a picture of a wired handpad for the Si-tech servo controller. The buttons don't glow in the dark. They do have a different tactile feel however. The box is slightly smaller. The switch is replaced in the servo version with another button in the middle.  The cable comes directly from the box, no connector to fuss with at the box.
