Motorola EMDK performance

Hello.

 

I'm using the Motorola FX9500 Reader with two AN400 antennas.

 

When I run the Motorola C# sample programs the tags reading is too slow (about 30 seconds to start reading).

And sometimes it doesn't start to read.

 

But when I run the Motorola SessionOne the labels are read instantly.

 

Can someone explain it for me?

Why the sample codes are taking too long to start reading?

 

Please, help me.

 

Thanks.
