Core wire
2.
Aluminum foil
3.
Braid shield

Shielded RJ45 connector
Strip the cable.
Length of the stripped
cable: 20 mm
Strip off the braid shield and cut
the aluminum foil and unwanted
materials.
When stripping off the outer jacket, take care not to damage the braid shield
or aluminum foil.
Remove the outer jacket.
Arrange the core wires according to the pin assignments and cut them
neatly (exposing a length of 12 mm).

Insert the arranged core wires into an RJ45 connector according to the pin
assignments and crimp the connector with the crimping tool.

Outdoor network cable
Terminate a connector on the other end of the network cable, and then test the cable
for continuity using a network cable tester.

In addition to Ethernet services, the P&E port of the RTN 310 receives PoE signals from power
sourcing equipment (PSE). An outdoor straight-through cable is used to connect the P&E port and
PSE.
The pin assignments of the P&E port on some Ethernet power supply equipment may be different
from those on the RTN 310. You need to make a network cable based on the pin assignments of the
two P&E ports.
Optional: Use a multimeter to measure the impedance of core wires. The impedance
difference between core wires must be less than 5%.

•Before crimping, ensure that the core wires are fully inserted in the RJ45
connector.
•Use the crimping tool to crimp the connector with force.
•After crimping, verify that the connector has been crimped tightly.
