RIO comm adapter 1336-GM1

Hello,

can someone tell me how to install 1336-GM1 RIO card inside a 1336-Plus II drive (small Frames A).
I excpect it should be mounted in the position of HMI (adapter 1),but i need to be sure.
i didn't get to find some drawings.

Please help.

Hello,
i found in some documents i have to use 1336-GMS1 (GM1 with Snap-In Cradle).
do you know what does "with Snap-In Cradle"stand for?
can this GM1 be adapted ?or should we buy a GMS1?
