Posted 29 Jan 2019 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. Share this post Link to post Share on other sites
