Xpressnet Wiring - Lenz Digital Plus LZV100 Operation Manual

LZV100 Command/Power Station 27

9.4 XpressNet Wiring

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 may install your XpressNet in any configuration so long as
there are no loops. To install branches use a standard RJ14 or
RJ12 splitter or Tee (available through your dealer or wherever
phone products are sold).
For exceptionally long XpressNet installations, (more than 300ft),
you should use wiring with at diameter of at least 20 gauge to
ensure that sufficient power is available to power your handhelds.

The ends of the XpressNet Network lines A and B should be
connected to the resistor, which is enclosed with the LZV100. The
resistor has a value of 120 Ohm.

Which wire is best for use with XpressNET?
The minimum gauge of the wire in the XpressNet should be 24
gauge. In practice so-called "bell wire" has proved efficient. This
can be acquired cheaply. It is sufficiently twisted and available in
various colors. If you are using LA152 adaptors then common 6
wire phone cables can also be used.
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
