Port Server II Data

why my port server ever sends to me at the beginning of the data frame characters like 0x82,0x8A,0x4A,0x42?
It’s a part of the Port Server’s Protocol?

I’m not sure what those hex codes mean exactly, nor do I know whether or not you should be seeing them.

That may depend on how you have the Portserver II configured, what you’re doing with it, etc. This might require some indepth tracing, best bet would be to call Technical Support and open a case.
