Is it possibile to use a CAN transceiver to send RS485 data?
In the CAN recessive state, the differential voltage can be zero. This is not a valid RS-485 signal level.

However, many RS-485 receivers have built-in fail-safe logic that interprets an undriven bus as logic one, and a bus without such logic is supposed to have fail-safe biasing resistors with the same effect. So if you wire the bus so that the CAN dominant state (CANH > CANL) corresponds to RS-485 logical zero (A &lt; B), then it might actually work.
