MESA 5i25-7i76+7i77 lack of tabs

Hello dear users LinuxCNC. Sorry for my English but I need help
In PNCCONF no additional tabs "SmartSerial". must be so


And I have only the tabs I \ O Connector 2 and I \ O Connector 3

Is this a pic of what you have or what you want?
This pic is correct.

If that's not what you have, what version of linuxcnc are you using?

Thank you.
  Figure that's what I want.
I've already figured out - I had version LinuxCNC 2.5.0, half an hour ago updated 2.5.3 - tabs appear.
Thank you.
