Connect an EPIM-T to a Twisted Pair Segment as follows:
1. Connect the twisted pair segment to the module by inserting the
RJ45 connector on the twisted pair segment into the RJ45 port on the
module. See Figure 3-12.
2. Check that the LNK LED for the port is on. If the LED is not on,
perform each of the following steps until it is:
a. Check that the 10BASE-T device at the other end of the twisted
pair segment is powered.
b. Verify that the RJ45 connectors on the twisted pair segment have
the proper pinouts. Figure 3-13 shows the RJ45 pinouts.

c. Check the cable for continuity.
d. Check that the twisted pair connection meets dB loss and cable
specifications outlined in Section C.1.1, 10BASE-T Twisted Pair
Network.
