Plastic-Fiber Optic Interface: RS232 Interface, Model 81029

Model 81029 - Application:
PC connection over fiber-optic cables, Power-saving version for short distances

Background knowledge:
Power for the interfaces
With the Interface model described here, a 9-pin special version is available
in addition to the other fiber optic compact interfaces. The transmission
distance is limited to 20m, but the connected RS232 port only sees
a load current of approx. 2mA. With this version it is also possible to run
on lower power RS232 interfaces without the need for an additional voltage
source.

A pin- and function-compatible converter for distances up to 80 meters is
available by using Interface model 81009.
