Hello,
I have a project that will use CAN. In CAN network there must be 2 (and only 2) resistors called "termination resistor", or ZT. These ZT are 120ohms resistors mounted between CAN_H and CAN_L.
I want to allow the user to use, or not, the ZT in my project by selecting this "parameter" in the software.
I plan to use an opt-isolator drive by an teensy digital output (here D21). The purpose of using a opt-isolator is to isolate the CAN network from the logic. Do you think my schematic will operate ?
Thanks,
Manu
