Testing Ethernet connection
A standard RJ-45 modular jack is available on the FDAP Gen3 Power and IO board. The RJ-45 jack may be
used to test cable integrity after terminating the cable at the IDC connector. After terminating the field cable at
the IDC, connect the cable tester to the RJ-45 jack. An end-to-end cable test can then be performed to ensure
proper wiring at the IDC connector.

When powered from an external DC source, the power cable should be terminated directly onto the
terminal block of the DC Ferrite Assembly. Connected wires then pass through the mounted ferrites
on the assembly board, which then connects to the two-position terminal block on the Power
Board. The polarity of the connector is marked next to the connector on the Power Board. The
power cable should be shielded and the drain wire grounded inside the enclosure as displayed in
"Figure 7: Ethernet and field DC power".
Secure all connections and wires and connect the cover-ground connection lug to the enclosure
cover to complete the wiring.
