Data connection
The FreeCon Active PROFINET-POF-Repeater has two 100BaseFX Ethernet ports for polymer optical fibre
(POF). These SC-type fibre ports are fairly straightforward to connect since optical-fibre connections do not
require the circuit needed for electrical signals.
One of the optical lines is used to transmit data from device I to device II, and the other optical line is used
transmit data from device II to device I, for full-duplex transmission. Remember to connect the Tx (transmit)
port of device I to the Rx (receive) port of device II, and the Rx (receive) port of device I to the Tx (transmit)
port of device II, as shown in the illustration below.

Grounding/earthing
Proper earthing and wire routing are important in order to limit the effects of electromagnetic interference
(EMI).The earthing on the FreeCon Active PROFINET-POF-Repeater is established using the functional
earth from the power plug.
