How can I setup a simple labview vi that will do basic serial port I/O? I just want to send a command string, read back the response, and be able to configure the serial communication (baud rate, data bits, stop bits, parity).
I have an instrument that needs the serial line configured for 2400 baud, 7 data bits, Even parity, 1 stop bit. I don't know how to setup the serial port init vi for this (for example what is the labview code for even parity? Is it an I8 data type? ).
I downloaded the serial loopback VI, shorted pins 2 and 3 on my serial cable, and successfully ran the VI which tests the hardware.
Next I configured a modem/serial communication program called minicom for 2400 baud, 7E1 and am able to successfully r ead and write to the instrument.
So far so good, now just to make it work with labview and build a simple serial I/O vi. However I cannot find any decent documentation on serial I/O. I tried to modify the serial loopback vi by adding inputs for data bits, stop bits, parity, baud rate but could not make it work. I could not find any other examples.
Can someone help with this, or point me to a good vi or some detailed documentation?
