MMI display J685
Display unit for front information display and
control panel control unit
On the Modular Infotainment System, an LVDS* signal is used for
video transmission from the electronic information systems
control unit 1, J794, to the MMI display, J685.
With the Entry plus and Standard MIB, the video output resolu-
tion is 400 x 240 pixels, and on the High-spec MIB 800 x 480
pixels.
The electronic information systems control unit 1, J794, is con-
nected to the MMI display, J685, via a sub-bus system (private
CAN bus). This is a CAN bus with a data transmission rate of 500
kbit/s. The electronic information systems control unit 1, J794,
uses it to control and monitor system statuses on the MMI display
(on or o, temperature, error status, etc.), for example.
