Question 25: How do I use CVT-485_422-1 / CVT-485_422-3 as a RS-232/RS-422 converter?
Answer: CVT-485_422-1 and CVT-485_422-3 are dual-function converters, so they can be used to convert any standard RS-232 port into a two-wire half-duplex RS-485 port, or a four-wire full-duplex RS-422 port and vice versa. This is done through the Jumper settings on the terminal block. For example: Jumper 1, 2 & 3 are ON (shorted) by default, which is used for RS-232/RS-485 conversion. When all three jumpers are removed (opened), it becomes a RS-232/RS-422 converter.
