I am going to sell the keypad. It was a later version and was purchased more recently. I don't have a use for it. I am strictly an imager and already have the rig totally hooked up to my computer with all the software. I am most comfortable having all my tools available on the laptop. Everything was running great last night even my old USB serial cords from Radio Shack. I had quite a difficult time finding the drivers. I will sell the keypad and go ahead and purchase an CP3 or CP4.
