The rdc232fos safely and easily connects your
panel mounted RS-232 devices to fiber optic
cables up to 11 km long, providing the ultimate
in isolation, surge, and noise protection. Even
the RS-232 port is galvanically isolated from the
DC supply ground. The ST connector, plus
quality Hewlett Packard components used are
guaranteed to work with 9/125 µm fiber sizes.

Testing - the top screw-terminal Rxd can also be used to easily
test your fiber optics link. Connecting a +5 to +15vdc signal will
force the fiber transmitter on, so you can easily see the light at
the remote end - even with the naked eye. For example, 9v
radio battery could be used to provide this test signal.
