Reading Arduino Serial through USB 6211/6501

Hi Everyone,

I'm working on a project to acquire data from 10+ pressure sensors (I2C) at the same time, with a frequency of 500Hz (per sensor). What I was planning to do is to connect the pressure sensor to an arduino and output data from the arduino serial which then gets routed through a digital line on the USB 6211/6501 (I have a 6211 for testing and I'll purchase a 6501 for the final setup). I'm new to digital data acquisition so I'm not sure how I would have to set up the 6211/6501 so that it matches the baud rate of the arduino. I haven't tried this yet but I wanted to get feedback on the feasibility of this.

Thanks.

That does not make any sense. You cannot connect the arduino serial output to anything but a serial port and the-6211 and 6501 devices are not. You would simply connect a USB-Serial converter to your pc and use that.

I understand the 6211 and 6501 are not serial devices, the digital lines operate on ttl while the arduino uses serial ttl. I was assuming the 6211 and the 6501 could handle the serial communication based on the software configuration. I see now that I should not have assumed this, thanks for your reply.

I will look at getting a usb hub for data acquisition.
