Hi !
Iīm still in favor of implementing IrDA as the ultimate security opto isolation.
Yesterday I found some websites (some in german) where itīs described how to
build an IrDA adapter (plugs to connectors available on most modern mainboards)
for 5-10$. Itīs very easy.
Look at the following pages for details:
http://tscherwitschke.de/irda.html
http://www.infrarotport.de/
http://www.viishay.de/irdc.htm
What do you think ? Maybe we could set up a poll to see what people would
prefer ?
The other option would be to use the RS232 port and some optocouplers.
Does anybody know what isolaton voltage is common in eeg equipment ?
I think the brainmaster has about 160V which sounds quite low to me.
Does anybody know types of optocouplers normally used in medical equipment ?
Another idea is to built an optocoupler by ourselves using phototransistors and
IR LEDs. That would probably also result in a very high isolation voltage.
Moritz
