15.With the RS485 extension module, it will cost more, can I connect the RS485 pin built-in CPU directly?
You can connect it if the CPU is DC type, you know the pin RS485 A and RS485 B has no isolation inside, so AC type is not allowed to connect, it is very dangerous. The pin of the connector can be found in FAQ6.
