I want to send a command via serial port so I can turn an OUTPUT to ON or OFF I tried using different serial software and I am able to connect to my M1 Gold. I can see updates being displayed on the screen. However, I tried sending a command such as turning OFF output 9, but looks like my M1 is not receiving it. Is there something I need to enable on the M1 so that I’ll be able send via serial connection?
I got it working by adding \r\n at the end but it’s intermittent. I used this command to turn on output 9 0Ecn0090000000D1\r\n from the 2009 serial documentation, the checksum was D8. Someone from a forum told me to use D1 Now, I’m trying to turn off output 9 but this command fails 09cf00900DC\r\n
