  • Page 4: Introduction

    Introduction EB+ CAN HUB is an ISO 11992 router for 12 / 24 V EB+ EBS systems. It has three EB+ Power A (ISO 7638) connectors, sharing power and lamp connections but each having a separate ISO 11992 node and an input to connect an external pressure sensor for a commercial vehicle not equipped with ISO 11992 (i.e.
  • Page 5 Installation EB+ CAN Hub Guide The ISO 11992 CAN Bus is limited to 40 meters, where 22 meters is allocated for the truck (towing vehicle + Suzie connection) and a maximum of 18 meters for the trailer (towed vehicle). The maximum length to an ISO 7638 connector installed at the rear of the trailer is 15 m.

    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.
