I ordered a relay module from Amazon to control a projector screen and I’m having issues getting the received data working, I assumed it was something with the AcK but I must be missing something.
The relay has very simple commands:
A11T = Relay 1 Open
A10T = Relay 2 Close
A21T = Relay 2 Open
A20T= Relay 2 Close
Using Hercules when I send A11T the return is OUT1 ON
When I send A10T the return is OUT1 OFF
In V-Control when I sent A11T the Return is OUT1 ON&h0D&h0A
So I assumed the ACK should be 0D0A but when I use OD0A as the AcK in Hex and set the Timeout to 500 I don’t get any Received data back
Anyone have any suggestions? Or a suggestion on a tool that shows the RAW serial data being sent back maybe I’m missing something.
Thank you
