I have a device for pulse width modulation (PWM) with serail communication. It works fine with hyperterminal. In hyperterminal, I have to enter % duty cycle like say 50. When I type the 50,
it doesn't show the number, but once I hit the enter button; 50 % duty cycle is applied to device and device automatically sends back the % duty cyle, in my case 50. I am having trouble in
operating this device with Labview. I tried diffenet examples available in Labview help like basic serial write and read.vi. This example doesn't give any errors but, the the PWM device
doesn't work. I have tried loop back test with pins 2 and 3 shorted on serial cable and that works fine. So I don't understand why I am not able to communicate with device using labview.
Any suggestions on what I am missing. Reply would be greatly appreciated.
