92 Information SET-01
The XpressNet wiring must be installed so that the line starts at the
Command Station and ends somewhere on your layout. (Daisy
chained from Command Station via intermediate input locations to
the last input location.) Between the start and end you may insert
connecting panels or 5-pin DIN connectors anywhere. You must not
route the wire as a closed loop. Under all circumstances you must
ensure that the wires that are connected to terminals A and B are
twisted.
The ends of the XpressNet Network lines A and B should be
connected to the resistor which is enclosed with the LA152 adapter
The resistor has a value of 120 Ohm.
Terminating the XpressNet with a resistor
Which cable is to be used for the XpressNet?
The minimum gauge of the wire in the XpressNet should be 24
gauge. You will have to make sure that the cables which you have
connected to the terminals A and B are twisted. In practice so-
called "bell wire" has proved efficient. This can be acquired cheaply.
It is sufficiently twisted and available in various colors.
How long may an XpressNet network be?
For reasons of physics the maximum length of the XpressNet
depends on the kind and size of the wires used for the XpressNet.
With normal telephone wire the length should not exceed 300 ft. If
you install a twin-core, twisted cable for the signal lines of the
XpressNet you can increase the length to up to 3000 ft. without
problems.
