I'm not familiar with the spiderbox but I assume it will be the same way to put in a cline you can correct or remove post if it is not.
How to create CCcam.cfg file and put a cline in it:
1.Open notepad
2.Copy and paste your cline in it
3.Select File>Save As option
4.In the Save as type option select All Files (if you don't do this you will end up with a .txt instead of a .cfg file)
5.In File Name put exact name: CCcam.cfg
6.Save it
you put this in your usb and update your line this is the way I've done it with other recievers I've had.
