I have Alicat MFC MODELNO.: PCP-15PSIA-D. It has DB9 female connector on top of it. I have checked my communication using USB to serial connection for it and it's working. Now I want to connect my Alicat device with my VI using ethernet. For that I used USR-TCP232-302 converter. I can now read the data from Alicat but can not write values in the device. (My Alicat device is in streaming mode.) One of the command I sent it is: "@@=a" + "carriage return constant" which changes unit id of the device to "A".
When I used COM port it sends command to change the mode from streaming mode to polling mode. Which is working. And yes I have tried to send command via ethernet using polling mode as well.
