I'm creating a desktop application in Visual Studio (VB.Net) that reads from a serial port. The end device is a pressure transducer.
I can successfully connect to the COM port, but I never seem to recieve any feedback from the device. Do I need to first query it in order to get something back?
My settings are as follows (as per AN197):
Baud rate = 57600
Parity = None
Byte size = 8
Stop bits = 1
Is there a specific query I must send?
Many thanks in advance.
I have some questions:
1) Is this CP210x device on your own hardware or is this a part of a third-party product?
2) Has the device been customized at all from the factory default configurations?
3) Have you tested sending/receiving data with a terminal application (e.g: Coolterm, Teraterm)? Can you read data with these apps?
Hey there, thanks for the reply.
The hardware I’m using is a WIKA CPT2500 pressure transducer and cable which I think is a serial to usb conversion cable. I have checked in the device manager and it’s showing the Silabs CP210x bridge driver.
As for customizations, I’m not sure. I bought the hardware as a unit.
I have not tested it via terminal purely because I am not 100% sure on how to, would you mind explaining how?
The unit can be found on the Second page of this pdf. The software on this pdf is working perfectly fine with the sensor. When connected and the software is ran, I can place my finger over the end of the sensor and see pressure fluctuations on the graph.
Thanks very much in advance.
I'm not familiar with WIKA CPT2500 pressure transducer but I think you can use any kind of terminal (e.g: Coolterm) to connect to the device and send command to it.
I think it should be the same way you'll do with your desktop application, shouldn't it?
I see that WIKA CPT2500 should be use with USBsoft2500, shouldn't it?
I think you should contact WIKA to know more how to connect to this device.
