There is plenty of info out there on Oscam configuration and it's not exclusive to Protek.
Search and you will find.

Try this example.....

e.g. Typical C-line

C: example.server.com 12000 user pass no

Converts for oscam.server to:

[reader]
reconnecttimeout = 5
label = remote
protocol = cccam
device = example.server.com,12000
account = user,pass
group = 1
blockemm-u = 1
blockemm-s = 1
blockemm-g = 1
blockemm-unknown = 1
caid =
cccversion = 2.1.4

NOTES:
1) NOTICE on the device line the 'C: ' is dropped and the comma added between server address and port number
2) NOTICE on the account line the 'no' is dropped off the end of the line (if you had one anyway) and there is a comma added between the username and password
