Serial Comunication

Hi Everyone,
I have some problems with serial comunication with node-red. In my application I send data from Groov Epic to computer with serial comunication (USB-Serial converter).
If I send a string through inject (where I write the message) there is no problem, but when I want to send a string of my strategy I read a different value.
Where am I wrong?
What is the architecture that I have to follow?


Have you put a debug node on the output of the serial node to see why the actual data coming in is different from your Inject node?

Thanks a lot I solved the problem.
