1.7.5.8 Wiring the Ethernet Interface
A modified XGF868i can use the Ethernet interface to communicate to a local area network. An optional Ethernet card
with a unique MAC (IP) address (installed only in slot 2) includes an RJ45 connector. To connect the
Ethernet-enabled XGF868i to the network, insert the jack of an RJ45 cable into the RJ45 connector, route the cable
through one of the conduit holes using an appropriate cable clamp, and wire the other end of the cable to the
Ethernet network according to the manufacturer’s instructions. An external connection is required between the
Ethernet option card and the XGF868i RS232 connector, as shown in Table 4 below and Figure 11 .
Note: The MAC address for a specific XGF868i is included with the customer documentation. For more information
on setting up the MAC address, refer to Appendix C of the Programming Manual.
1.7.5.9 Wiring the Foundation Fieldbus Interface
To connect the Foundation Fieldbus interface to the XGF868i, make the network connections at J8, pins 1 and 2, as
shown in drawing Y of Figure 11 . As an option, you can connect a shield to J8 pin 3, depending on the network wiring.
No connections are made to J9 under normal operation. If you need to reset the network board to factory defaults:
1. Connect a jumper between J9 pin 2 and J9 pin 3.
2. Power cycle (i.e., turn off and on) the XGF868i.
3. Ten seconds after the power has been restored to the XGF868i, remove the jumper to return the network board to
normal operation.
