FIBER OPTIC QUESTIONS

9) USING TWO SerialComm RS232/RS485/RS422 TO FIBER OPTIC CONVERTERS, MUST THE SAME (RS232, RS485, or RS422) COMMUNICATIONS STANDARD BE CONNECTED ON BOTH ENDS OF THE LINK?

Answer: No. The RS232, RS485 and RS422 standards can be mixed and matched, on either end of the link so that, for example, an RS232 device can be connected to one side of the fiber link with an RS485 or RS422 network on the other side. Any combination of the RS232, RS485, or RS422 standards can be connected at either end.
