SWCAN Wakeup Frame with PCAN-USB PRO

[obrockmann]

Hello,

I want to wake up a node on a SWCAN (GMLAN) by sending a 0x100 message. However this does not seem to work (node does not wake up). When I monitor the traffic on the bus when this node is been woken up by another node I just see the 0x100 message with all payload bytes zero. I am not very familiar with GMLAN. Can I wake up this node with the PCAN-USB PRO?

Thanks, Oliver

Hi,

do you use a PCAN-AU5790 Adapter (IPEH-002040) on the PCAN-USB-Pro? If so, please set the mode pin to wakeup, see page 11 of the PCAN-AU5790 manual for more details:

The single wire system (J2411) needs a different voltage level for wake up signals.

Hello,

you can use a high voltage wakeup on a LS-CAN bus
CAN-ID=0x100,no data

To wake up any LS-Devices behind a gateway you can use
ID=0x101, length=4, Data= 0xFD - 0x02 - 0x10 - 0x04 or
ID=0x101, length=8, Data= 0xFD - 0x02 - 0x10 - 0x04 - 0xAA - 0xAA -0xAA - 0xAA
