This class will allow to manage an icv712 board.
The ICV712 is one slot 6U VME board (produced by ADAS), performing digital to
analog conversion of 8 or 16 12-bit channels. Each channel is galvanicly
isolated and can be configured independently as current (in the range
0 to 20 mA, 4 to 20 mA and 0 to 10 mA) or voltage (in the range 0 to 5
V, 0 to 10 V, -+5 V, -+10V).
