I am using a motor controller that communicates through a serial port at 9600 baud. I use the Labview to generate the specific command that we want the motor to execute, (speed, direction, time etc.) which is a short string like "/1J97E0M\r " Each character in the command specifies something for the motor to do.
Is it possible to calculate how many times per second a command like this can be sent with data rate at 9600 baud? For example, is it possible to know how many bits the string "/1J97E0M\r" is? Can this value be divided into 9600 to calculate the maximum rate that command strings can be sent to the controller? Is it that simple?
Thanks

The number of bits is obvious but it's not that simple. The motor has to interpret the data, act on it, etc. This response time/max data rate would be specified by the vendor.
And please post similar questions to the instrument control board. This has nothing to do with NI's digital I/O products.

Thanks, Dennis. I posted it here because I thought this board was for I/O, but, if it is for NI I/O exclusively, then, I will only post questions about NI products here.
