3.7.3 Sharing pressure sensor signal
For EKE 1A, EKE 1B, EKE 1D up to 5 controllers can share one Ratiometric pressure transmitter readings. To get a
correct acquisition on all the units all the three wires (GND, 5V and transmitter signal, output) must be routed to
every unit

(GND, 5V and transmitter signal, output) must be routed to every unit
 NOTE:
For a correct acquisition on all the units all the three wires (GND, 5V and transmitter signal, output) must be routed
to every unit
In EKE 1C, a physical pressure transmitter can only be shared via wired CANBus or Modbus
Sensor Signal sharing via CANBus in EKE 1C, 1D in EKE 1C, 1D Signal can be broadcasted once per second to all
the following parameters enable/disable broadcasting of local signals (refer to the con guration parameter section):
