Hello,

I am controlling my PVCAM-supported-CCD camera (from Princeton Instrument) in matlab through the USB serial port. I have recently wanted to scan the temperature of this camera in MATLAB, then will set temperature when it is reasonable to acquire the image.

I have tried to use serial commands fscanf to do this, however it is not quite successful when applying to USB serial port. I think these commands are only for controlling with RS 232 port (DB 9/25), not for USB.

If some body have successfully scanned temperature of PVCAM Support camera in MATLAB, please let me know.

Thank you.

Hi Du,

I have not scanned temperature of PVCAM Support Camera, however I have used a USB-to-Serial adaptor.

The functionality and robustness of the USB-to-Serial adaptor depends on how well the adaptor driver emulates a real serial port.

The better the driver, more robust and reliable the result.

Which adaptor are you using? I have successfully used IOGear, Belkin and Keyspan in the past. You might want to give one of these a try.
