Dear Friends
I hope someone can help me on this problem. I am working on a project in my workplace to create a interface circuit for RS232. My problem is, I need to detect a LED and a relay turned on. Once these 2 device has been turned on, I need to detect the signals from both and send it thru RS232 to trigger my software. I am attaching the part of the circuit which shows the LED and Relay. Hope someone can show how to tap the voltage or current from these device and feedback to RS232 by creating a interface circuit which software able to detect it.
Thanks
