Unit RS232 issue

  • Hello. I am using the rs232 unit module to read data from a device. The device will output continuous data via it's rs232 port once turned on. The issue is when I turn off the device and turn back on, the rs232 unit stopped reading the data until the rs232 cable is disconnected and reconnected. This is certainly not ideal in real world application. Does anybody know what cause the issue and how to fix it?

  • You need to detect when the device is disconnected and then reconnected in order to stop and restart communication. RS232 is not made for Hotswapping.
