I created a small LCD display that uses the serial output of the Print instruction to display data. I have used this for years using the RS232 port and now I want to use it with the C2 port. When I switch the data wire to the C2 port the display doesn’t work but if I use the RS232 port the display works properly. Below is the instruction I use for the RS232 port:
Print(2,9600,"Batt.(V)=",BattVolt, " ")
The instruction I use for the C2 port:
Print(4,9600,"Batt.(V)=",BattVolt, " ")
What is the difference between the RS232 and C2 port that prevents this from working?
Thank you for your help.
I switched loggers from a CR206 to a CR206X and now it works. Maybe there is a difference between the two loggers or the CR206 is faulty.
