Manual VN1600 Interface Family

2.8.4 Bus Configuration
Piggybacks
An advantage of the VN1640 is its four Piggyback plug-in locations (CH1…CH4).
Depending on requirements, electrically decoupled CAN High-Speed, CAN Low-
Speed, CAN Single Wire, J1708 or LIN transceivers may be used. CH5 is reserved
for dedicated IO tasks.
Figure 28: Piggyback plug-in locations for CH1…CH4.
Note: LINpiggies have to be inserted before CANpiggies (in ascending order). If you
intend to use only one LINpiggy, please use the first plug-in location (CH 1). J1708
should be handled like CAN here.
