Wake-up via CAN

Note: This function is only available if a CAN transceiver
module with wake-up function is present for the used CAN
channel. For all CAN channels, this is the case with standard
equipment.
When on a CAN channel a message is received, the PCAN-Router
Pro turns on. This CAN message and all further ones coming in
within the wake-up period of 165 ms are not processed by the
PCAN-Router Pro.
5.7.3

Wake-Up Externally by High Level

On each of the ports CAN 3 and CAN 4, a High level (at least 4.5 V)
can be applied to pin 4 to switch on the PCAN-Router Pro.
An external wake-up signal is required if none of the CAN transcei-
ver modules in the PCAN-Router Pro has a wake-up function.
Tip: Possible external wake-up signals are the supply voltage
for the PCAN-Router Pro or terminal 15 "Ignition" in a motor
vehicle.
