First off make sure the receiver is updated with the latest available firmware (dated March 27th, 2015), providing that's flashed the firmware has OScam built in and active when the receiver boots up so you'll be ready to configure...
The OScam Webif (looks, works and is like OScam Webif on most any other receiver) can be accessed at http://ip-address-of-receiver:8888, click on the readers sections, make any changes you want, save and then restart.
You can also access softcam settings via the on-screen menu by pressing MENU > Live TV > Left Arrow > CAS - but I would suggest sticking to the OScam Webif for changes and saving/restarting etc.
Any problems finding the firmware mentioned above let me know and I will upload it on here, it's a few hundred MB though so will probably have to upload to somewhere externally and link to it on here.
sorry to jump in, i got one of these (evo xfinitiy) which i think has the latest firmware , has oscam , the problem i have is putting my line in and saving it . Lavaman i would be most grateful if you can help me on this. thank you
When I go into service lists I got
service 1 myxcamd (xcamd) =off
service 2 mymorecam (morecam) =off
service 3-14 add service
but still I can't add my line even after pressing the red button , it just won't save it
theres a oscam folder to ftp your oscam file into its in a folder that's something like emmc or something like that just need make sure ftp is switched on in settings on box settings.make sure all those switched on especially constant cws,just press red button to save as is
