NOTE! All instruments are accessories.
CIU - Control Interface Unit
The CIU is the “translator” between the control unit
and the customer’s own control panel. The CIU has
two serial communication links, a fast one and a slow
one.
The fast one is a so-called CAN link. All data related
to instruments, indication lamps, connectors and po-
tentiometers is controlled by this link.
The slow link manages diagnostic information for
flashing codes etc.
DU - Display Unit
The DU is an instrument panel which shows engine
working values graphically on an LCD screen. It con-
sists of an computerised unit for permanent installa-
tion in a control panel.
The DU is connected between the engine control unit
and the CIU or DCU.
