MobiDICK is a complete test bench for
super-drawers
Will be used during the maintenance in the
long shutdown of 2013
Present system (MobiDICK3) based on:

Now there are only 3 systems available, we
need a fourth one to test 4 barrels at the same
time…
No replacement for some modules (CPU)
Obsolete technology
Reduce size and weight
Expand compatibility with the new front-end
electronics (Upgrade demonstrator)

CANBus power problem
l 
l 
Super-drawers expect to have power from MobiDICK side but
Motherboard + dongle does not provide power
Line with 12V has to be plugged into the CANbus cable from inside
the box
