Robust DataComm rdc232fo-dv-2p-st Converter Guide De Spécification
The rdc232fo safely and easily connects your
panel mounted RS-232 devices to fiber optic
cables up to 4 km long, providing the ultimate in
isolation, surge, and noise protection. Even the
RS-232 port is galvanically isolated from the DC
supply ground. ST or SMA connectors can be
selected, plus the quality Hewlett Packard
components used are guaranteed to work with
62.5/125, 100/140, and 50/125 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.
