Caravan Control Unit Parameters Of Digital Inputs, Function - GF54.21-D-5027TSA

Model 447 

with code JA3 (Intelligent body control.) 

with code XM7 (MOPF II) 

Model 907, 910 

with code JA3 (Intelligent body control.) 

General 

The digital signals are used to read in digital signals (0 or 1), and they can be read out by the internal software.

The MB Advanced Control, control unit (N175) can operate up to 29 digital inputs. Of these, there are 16 specific digital inputs with wake-up capability and 13 specific digital inputs with no wake-up capability. Along with the 29 digital inputs, there is another wake-up-capable input for reading in the Bluetooth® Pairing/Reset pushbutton switch

Parameters for digital inputs 

All digital inputs are operated as "low active" ones, i.e. connected pushbutton switches switch to ground.

The LED in the Bluetooth® pairing/reset pushbutton switch is electrically powered by the pulse-width-modulated low-power output, and it can be actuated at a maximum of 10 mA.
