HI,
I am using USP-8451 OEM Version for control some SPI devices. 8451 Board will be part of complex system and should be installed inside metallic box. There are three mounting holes on the board. Two of them are just holes, there is no any metallization, but third one (close to the board center) has metallization around the hole. But it is looks like that metallization polygon is disconnected by default from other circuits (probably this is not completely correct, because I've check only connection to GND circuits). So, the question: how this metallized hole should be used during assembling? Can it be connected to box case or it should be kept disconnected/isolated from any other shields/grounds etc..?
I've tried to find some info in specification and installation guide, but there is no any information about this metallized hole.

Roman,
The metallic screw hole on the 8451 is not connected to any other parts of the board, and does not need to be taken into consideration for any isolation, shielding or grounding.
