Figure 5-2 EPIM-100TX Crossover Switch

Connect an EPIM-100TX to a twisted pair segment as follows:

1.Connect the twisted pair segment to the module by plugging the RJ45 connector on the twisted pair segment into the RJ45 port on the module. See Figure 5-2.

2.Plug the RJ45 connector at the other end of the twisted pair segment into the other device as appropriate.

3.Check that the LNK LED on the EPIM-100TX is on. If the LED is off, perform each of the following steps until it is on:

a.Check that the 100BASE-TX device at the other end of the twisted pair segment is powered up.

b.Verify that the RJ45 connector on the twisted pair segment has the proper pinouts.

c.Check the cable for continuity.

d.Check that the twisted pair connection meets the cable specifications outlined in Section 3.1.2.

e.Check that the crossover switch is in the correct position.
