Hi, I am trying to control a Harvard Apparatus 22 Syringe Pump with a simple VI driver. I can communicate with it using the labview "Basic Serial Write and Read" example, but the device requires a carriage return (CR) aka "/r" termination character, and I do not seem to be able to enable/set this value. I have added a property node as specified "adding a termination character to VISA serial writes" document, but this does seem to be able to set/enable the CR termination character. I have included the orginal VI file, and my modification of it. Any assistance in this matter will be greatly appreciated! Cheers, Tim.

Instrument Control (GPIB, Serial, VISA, IVI)

Try using Hyperterminal first, if that works, then it is probably needing proper termination characters in the LabVIEW code.
