The first thing you have to do is download the Cas Studio software, for your Cas programmer, which is needed to program a Diablo Cam:

Do not connect your Cas programmer until after you have installed the drivers, it makes it easier for your computer to install them.
Once they are installed connect your Cas programmer to your computer using just the USB cable, this is all you require.
Next you need to download the latest Underworld file, this is currently underworld 153, if you type underworld153 into any search engine you should quickly find it. You will probably need winzip, winrar, or 7-zip to uncompress the file before you can use it. Also download the latest Diablo Keys bin file to your desktop.
Copy underworld153.dup to your computer desktop, as it makes it easier to find for programming.
Programming the Diablo is quite easy:
Insert your Cam carefully into the Cas programmer.
Start up the CIS 8.6b software, you should have a shortcut icon on your desktop.
Click on the Cam Module tab, and the 2 Diablo Cam icons, this starts up the Diablo software.
It should automatically be set to the Upgrade Cam tab.
Click on the little icon, with 3 dots, at the end of the File Name: address bar.
Navigate to your desktop, underworld153.dup and click open.
A green light should now appear on the Start Update icon, click this and wait for the Cam to finish programming.
To get Digi TV you will need to update the keys, the easiest way to do this is by loading the latest Diablo keys bin file, which you should find at the same place you located underworld 153.
Click th Cam File System tab and click Connect.
In the right hand pane you should now see all the files currently loaded on your Diablo cam, including data bin and keys bin files.
In the lower left pane locate the newly downloaded keys bin file, highlight it, and click the green arrow pointing right.
Click yes to overwrite the old file and it should complete in seconds.
Once complete click the yellow Exit icon, this will bring you back to CIS 8.6b.
You now need to adjust the configuration settings.
Click on the Utilities tab, and the Common Interface Host icon.
You should now see underworld 153 displayed, click enter.
Enter the Configuration folder and change the following:
Emulators to ON.
Emulators priority to 1 Emu 2 Card.
Your Cam should now work.
