VN7570 Channel Configuration
VN7570/VN7572 are PCI Express Interfaces for FlexRay, CAN, LIN and J1708.
The interfaces provides eight channels plus one channel for I/O. Beside the four onboard CAN channels, four Piggyback plug-in locations (CH1…CH4) can be used for FlexRay, CAN and LIN channels (FlexRay2 only on VN7572):

In order to connect the device to the FlexRay/CAN/LIN bus or to use the IOs, one or more Piggybacks with suitable transceivers have to be inserted before. For CAN there are also on-board transceivers available.
A list of compatible Piggybacks can be found in Interfaces Accessories Manual.
LINpiggies have to be inserted after CANpiggies (in descending order). If you intend to use only one LINpiggy, please use the last plug-in location (CH4). J1708 should be handled like CAN here. Please refer to section Bus Configuration in the VN7572 Interface Manual for further details.
If a FRpiggy is inserted (CH1), only two additional LINpiggies can be used (CH3/CH4). A third LINpiggy at CH2 returns a configuration error in Vector Hardware Config.
