RE: RS232 card for PC with surge protection ??

["Ward, David" <DAvid.Ward@xxxxxxxxxx>]

If you 'robotic test rig' can work with one I'd advise developing this kind
of thing with a cheapo USB-RS232 adaptor from ebuyer

As an alternative, you can buy isolated Rs232 adaptors or you could make
your own with a couple of MAX232 style rs232-TTL convertor ICs and Otpo
isolators (put them in sockets ;-)

BTW  Yes you can get buffered or Optoisolated RS232 cards but they aren't
cheap!
see Blackbox,  Amplicon liveline, National Instruments etc...

Erm bit embarrassed as I have just blown the serial port on my PC running a
little robotic test rig I was playing with.. :-(
Somehow I got a power feedback of some kind that has blown the port..
(almost a pant wetting moment as my back was to it at the time)
Is there such a thing as a PCI rs232 (serial) card with a form of buffer or
surge protection ?

PS. Did I mention that it can't cost a lot of money... :-))
