External pressure sensor

EB+ CAN Hub supports communication between a towing vehicle not equipped with an EBS system (i.e. Truck
with ABS only system) and towed vehicles equipped with EBS system. This is done through the connection of an
external brake Pressure Sensor to the EB+ CAN Hub AUX port on the first trailer. The sensor provides information
about the pneumatic brake demand requested by a driver and EB+ CAN Hub converts it into an electric brake
demand signal and sends it to the trailers by generating the EBS11 (service brake demand) and EBS12 (pneumatic
control line and 1 x electrical control line) messages.
