Problem is on a data collection module on a production line talking to a PC via RS232 comms link. Direct connection with only 5 to 5, 2 to 3 and 3 to 2
The 0v of the data collection module is moving relative to the 0v of the PC and the comms ports have been damaged. Suspect track damage on the 0v tracks and/or the devices.
An off the shelf opto isolator barrier is needed. 5 or 24 volt supply available from the data collection module and a supply can be obtained from the PC.
Mains supply is not available at the production line where the isolator would be most effectively located.
I am trying to avoid building one from scratch.
