oscam reaader vs mgcamd difference

Hi Experts!

I have the following issue. I used before mgcamd plugin on Spark 1 to read keys from remote server.
Currently I have spark 2 and using Oscam readers.

The issue is that Oscam reader (newcamd, 093E) is blocked by remote server with message: "wcamd] disconnected: reason receive error1 on closed to remote server , rs 0".
In the same time mgcamd on spark 1 works perfect. In terms of basic config server, port, user, password, DES key everything is the same.

The question is what is the difference between mgcamd and Oscam reader commands to remote server? Is kind of signature present in commands? Is it possible to fake it to make remote server think that mgcamd is connecting instead of oscam reader?

PS For the second remote card server everything works perfect (newcamd, 0500).

Thanks.
