PCAN-Router Pro – User Manual

5.6
Power-down Mode
In power-down mode, the voltage supply is turned off for a majority
of the electronic components in the PCAN-Router Pro and the
current consumption is reduced to 470
μ
A at 12 V. The Power LED is
off.
In order to set the PCAN-Router Pro from turned on state to the
power-down mode, you need to deactivate the selfhold function.
This is done by transmitting a CAN message that is processed by
the PCAN-Router Pro and that sets the I/O function
70h (Special Out)
> Selfhold to 0 (deactivated).
If the PCAN-Router Pro is in power-down mode, a wake-up signal is
needed so that the router turns on again (see the following section).
5.7
Wake-up
If the PCAN-Router Pro is in power-down mode (supply voltage is
applied, Power LED off), a wake-up signal is needed for turning on.
The following subsections show the options.
5.7.1
Wake-Up with Supply Voltage
If the PCAN-Router Pro contains at least one CAN transceiver
module with wake-up function (this is the case with standard
equipment), the Router is switched on automatically as soon as the
supply voltage is applied.
If none of the CAN transceiver modules has the wake-up function,
an external wake-up signal must be used (see section 5.7.3 on page
37).
