I am trying to control a SainSmart 4 channel 12VDC relay from Labview and having some trouble. I was hoping to control the module via serial comms but this does not seem to be working. Can anyone suggest an example that I might follow to set this up?
The relay board uses the FT245RL FTDI chip. Labview examples for interfacing with FTDI chips can be found at http://www.ftdichip.com/Support/SoftwareExamples/CodeExamples/LabVIEW.htm
