PC to CP1E serial communication through RS232 built in port.

1 post in this topic

Hi all, 

I got a problem which i cant transmit data using TXD in CP1E. The A392.05 is not true means the port is not ready.

I can download and upload program using the port.

But when i want to see the data at putty nothing happen (of course because my port is not ready). LED comm also not ON. 

When i pressed any keyboard button the LED comm ON.


I tried with CPM2A, the data is sent and can be seen on my putty display.
