I have a USB relay module
that has an FT245RL onboard running the relays. The drivers are installed correctly, and I can see the board on COM3. I create a serial port object thus:
relay = serialport('COM3',9600,'Parity','none','DataBits',8,'StopBits',1);
but when i try to send a command (e.g. write(relay,1,"uint8")), i get no response. I can run the board usaing a stand-alone app (USB 8 Relay Manager v.1.4.exe), and after i have used that app to toggle the relays, I can then operate hte relays with my matlab code (after closing out the stand alone relay app of course).
So what's going on here?

Did you find a solution to the problem? Because I'm currently having the same problem and still haven't found a solution.
Thank you very much,
