Ethernet wiring
The FDAP has one Ethernet input for optional connection to a wired network or a wireless
access point. If the FDAP is connected to a wired Ethernet, you should run the Ethernet
cabling from the control system through the conduit to the FDAP site. You must install the
FDAP based on the Ethernet connection. If the Ethernet cable is connected, it acts as an
FDAP (access point) and if the Ethernet cable connection is removed it acts as a line
powered FR (routing device). Ethernet interconnection is limited to installations outside
Class I Division 1, Zone 0/1 locations. An 8-position Insulation Displacement Connector
(IDC) terminal block allows a twisted pair Ethernet cable to be connected to the FDAP
without stripping the wires or crimping on modular RJ-45 plugs. The drain wire from the
CAT5E cable shield should be connected to the internal grounding point on the conduit
hub. The cable should be of solid core type to ensure good signal quality and performance
of up to 100 meters.
Terminating the Ethernet cable
Perform the following procedure to terminates the Ethernet cable.
1. Strip the outer jacket of the CAT5e cable and connect the shield drain wire to the
internal grounding lug on the conduit hub.
2. Connect the twisted pair wires to the IDC following the color chart marked next to the
IDC. Note that the color chart on the FDAP Power and I/O board assumes that the
cable conforms to EIA/TIA 568B color code which is the predominant color code for
CAT5e cable. See the following table for the necessary adjustment if the older EIA/TIA
568B color coded cable is used. Most of the CAT5E cables conform to TIA/EIA 568B.
