Why does my SC4000 GUI say I have an SC6000?

The GUI is called the SC6000 Controller. There is not a separate GUI for the SC4000.

At the bottom of the status page it should show the correct ROIC and detector material type. 9803 for SC6000 InSb. An SC4000 should show a 9705, 9809 or 0209 as the ROIC type.
