4.2 Overall Description

In order to unify the driver interface of Advantech’s CAN series of prod-

ucts, a new DLL file named AdsCAN.dll has been defined. This makes it

possible to change the CAN card from PCI-1680 to PCL-841 without

recompiling applications.

AdsCAN.dll should decide which driver to call depending on the differ-

ent CAN cards.
