Re: Serial Communication

Hi Cole,
Your PCI controller ( the first problem). To be sure:





It is a RS232 and not a RS485 controller ?
You also measured the voltage at pin 2 and 3. No voltage ?
Is this controller visible in your windows system hardware list ?
Is the flow control for these com ports set to 'none' ? 
 
Your temperature controller (second problem):
 


The COM port on your PC works with the loopback connector. But you got no data from your temperature controller. Correct ? Do you have a manual for this controller?
