= Technical Information

Here is the information that we have or suppose about the different components of the system.

== Chassi
The chassi of the VMC is an ELMA COTS 3u VPX Tower Enclosure.
The chassi include a backpane and an integrated PSU that provides DC power to the boards.
The PSU accepts from 90 to 264 VAC and inclued Power Factor Control technology (limit reactive power).

#text(fill:red)[Q: It would be helpful to get a schematic or a photo of how the boards are installed in the chassi, and how they receive power.]

== 68PPC2 SBC
The board in the first slot of the chassi is a 68PPC2.
This board is connected to the Mission Computer (via the Comm. Converter Board).
It is unclear if this board processes some data or if it is only responsible for communication.
This board does have a quad-core CPU so it might be procesing data.

#text(fill:red)[Q: Info about the role of this card would be helpful in identifying the points of interest.]

== 68G5
The second board, installed in slot 3, is a 68G5.
The role of this board needs to be clarified. It is connected to the Software Control Module (SCM) but the role of both these components is unclear.


#text(fill:red)[Q: Info about the role of this card would be helpful in identifying the points of interest. In particular this board can be equipped with up to 3 modules. Knowing which module is installed can help assessing the interest.]
