3.7.0.1 Adapting the Ethernet Cable for Connecting to
BreezeACCESS SU-ODU
The 55 cm Ethernet cable supplied with the unit has crossed Ethernet connections which have to be
adapted for connecting the unit to a BreezeACCESS ODU:
1
Cut the cable as close as possible to the connector that should be connected to the ODU (the end
without the service box).
2
Use a crimp tool for RJ-45 connectors to prepare the wires. Insert them into the appropriate pins
of the spare RJ-45 connector supplied with the unit and use the tool to crimp the connector.
Make sure to do the following:
º
Remove as small a length as possible of the external jacket. Verify that the external jacket is
well inside the sealing cover when connected to the unit, to ensure good sealing.
º
Pull back the shield drain wire before inserting the cable into the RJ-45 connector, to ensure
a good connection with the connector's shield after crimping.
The cable should provide straight pin-to-pin connections on both ends. Figure 3-3 shows the
required wire pair connections:
NOTE
Sometimes there may not be a central lobe peak because vertical alignment is too far off; only two
similar peaks for the side lobes are detected.
