I'm trying to establish a full-duplex and then a half duplex communication and need to wire a device output to an RS485/422 to RS232 converter.
Here is the device output pins for full and half duplex modes:
And here is the RS485/422 to RS232 converter screw pins(DATA+ DATA- are for RS485 rest TXs and RXs are for RS422 manual says):
I have 3 questions here.
1-) Is my wiring below from the converter to the device correct for full-duplex?
TX+ <-----> RXD+
TX- <-----> RXD-
RX+ <-----> TXD+
RX- <-----> TXD-
2-) Here is most confusion at half-duplex wiring. Converter shows D for RS485, device shows another notation such as TXD. Here I don't get why they use TXD-/RXD- format for half-duplex. Why both shown? Anyway is my wiring below from the converter to the device correct for half-duplex?
D1+ <-----> TXD+
D1- <-----> TXD-
3-) And finally can I use the half-duplex mode with RS422 full-duplex wiring without wiring back for RS485?
