CABLES AND CONNECTORS
DB9F Null Modem Connector
Fig. 5 illustrates a serial connector for the field bus. Fig. 6
shows how to configure a Null Modem Cable DB9F.

Ethernet Connection
See Fig. 7 for MPC Ethernet connection.
Fig. 8. MPC Ethernet connector.
RJ-45 LAN Connector
The MPC provides a standard RJ-45 connector for 10/
100BaseT Ethernet LAN connection. This section describes
the pin layout for the RJ-45 connector. Most Ethernet local
area networks use twisted pair wiring. 10/100BaseT networks
are physically laid out in a star topology, where each piece of
equipment on the network is connected to a central switch.
The wiring is connected to devices using a plug that
resembles a phone jack called RJ-45. See Table 2 on page 5
for details.
Connect MPC to Switch
To connect a MPC device to a LAN via an Ethernet Switch, the
required cable should be configured as shown in Fig. 8.

Switch connections.
