Assembling the RJ45 Connector (for Network Cables)
The device has adaptive network ports and can connect to the switch using straight-
through or crossover cables. The BTU board of the U1911&U1960&U1981 can also
connect to the peer NT device using straight-through network cables. If you need to
prepare a straight-through or crossover cable, strip off the jacket of the twisted-pair
cable, insert the core wires into the eight-pin feet of a RJ45 connector according to the
pin assignment described in the following table, and use a crimping tool to crimp the
connector.
