Hi !
There´s no need to build our own optocouplers. There are ready-to-use parts
available. I´m favoring the CNY65B from Vishay/Telefunken right now.
I´m working on a circuit that is powered by the RS232C port.
The problem is
- to make it as RS232-compliant. as possible. There might be problems with
certain notebooks, for example.
- to make it powered through the RS232 Port (without external power supply)
- to make it fast enough for full 115kbit data-rate
Moritz
