A direct Ethernet connection is used to connect a TCU to X120 of the NCU. NCU and TCU are
suitably precon󹪝gured with IP addresses.
The IP addresses are not signi󹪝cant for further operation.
The TCU is connected to the NCU via a crossed Ethernet cable.
The direct connection of the NCU via X120 to the TCU automatically forms a simple system
network consisting of two computer nodes.
