NI USB 6210 commands

[word505]

I have an RS232 and the NI USB-6210 and I was wanting to know how would I go by getting the commands for the USB-6210. I was thinking about writing a program and was wanting to know the serial ports for it.

Hello Word505,

The 6210 is an M-Series USB DAQ device and there is no RS-232 interface available.  The DAQmx drivers required to use it should have been included with the device, or an appropriate version for your development environment can be found here:

ni.com/drivers search: NI-DAQmx

I would also recommend reading through the getting started tutorials available here:

So to clarify what you just said, If I had an embedded system I could not configure the USB-6210 commands to run program using a RS232?

Hi Word505,

Your phrasing is a little ambiguous, so there are two ways to interpret your question:

1) Can I configure the DAQ device, affect its output, or interpret data coming into the 6210 by way of RS232 serial communication?

-No

2) Can I use the 6210's digital input/output channels to communicate with an RS232 serial interface?

-Yes, this is theoretically possible, but I wouldn't recommend it.  The biggest reason for this is that you cannot buffer digital I/O, so you would have to send/receive symbols one bit at a time using software timing.  I've not tried it, but I believe that this would lead to all sorts of problems.

I have, and as mentioned ^^, it's not worth it.  Use a CP2102 or other USB-UART and talk to it that way.  MUCH easier.
