I did not understand which are my transmit pins A,B or Y,Z ?These names are not consistently applied by manufacturers and you may need to connect A on the computer to B on the instrument.
For RS485 which is half duplex Y & A would connect together and Z & B would connect together. You would have to use the flow control lines to only transmit or receive at any one point in time which can be achieved by connecting the !RE & DE lines on the IC together so when High you can transmit and when low its in receive mode. RS422 uses all 4 wires.I did not understand which are my transmit pins A,B or Y,Z ?
