Hi, Ilnur Salifov.

Long time no contact.

So the question is you want to use M40 boards as D40 boards in your new path. I will transfer this question to our system engineer. I will answer you with more details later.

Hi, Ilnur Salifov

After checked with the system engineer, the M40 can not be used as a D40. Because theres a one-way device in the board.

What one-way device in the M40 board? Tell in more detail, please.
