Getting newcamd to work with oscam - any ideas please?

Hi,

I have 2 sources for newcamd lines - one which I add into my oscam.server config file as below works:

[reader]
label = camster
protocol = newcamd
key = 0102030405060708091011121314
device = server,port
account = user,pass
group = 1
fallback = 1

Now if I put another set of newcamd credentials into the config - it doesn't work. Can anyone tell me why one would work and the other not when both sources are newcamd servers? Or have I been told one thing and they are another?

Thanks
