14.1 Adding an X-Bus to allow additional input devices
Your
Digital plus by Lenz
® SET-02 has the ability to easily expand
using its support of the X-Bus. The X-Bus is a leading model railroad
high speed network protocol. It is based on the electronic industry
standard RS-485 hardware. The key advantages of this protocol are
its expandability and the fact that it is supported by a growing
number of Model Railroad manufacturers. For wiring the SET-02 to
support the X-Bus refer to "Wiring the X-Bus" starting on page 53.
X-Bus-input devices cover a wide variety of options including a
variety of handhelds, Tower Cab, interface and compiler modules,
that is, all devices from which you control your model railway. In
SET-02 the LH200 is an input device and command station at the
same time, as described above. In its capacity as command
station, it not only generates the track format, but also evaluates
information from other X-Bus-input devices and converts them into
control commands for locomotive decoders and points decoders.
The X-Bus itself is the link circuit between additional input devices
and the command station LH200.
In order to be able to connect these X-Bus input devices to the
LH200, you need an adapter LA152. This adapter is fitted into the
connection between the LH200 and the LV200. If necessary, you
connect further X-Bus devices to the LA152 using additional LA150
adapters or 5 pin din plugs described later.
Via this X-Bus, information can be exchanged between the
additional connected input devices and the command station. So
that the command station in the LH200 can distinguish these
devices from each other and address them, each device on the X-
Bus has to have its own number, referred to as an X-Bus address.
Up to 5 additional X-Bus devices can be connected to the SET-02.
SET-02 supports the following X-Bus addresses: 1; 2; 3; 29; and 30.
The addresses 1 to 3 are intended for the connection of further
handhelds LH200 or LH100 as well as the Tower Cab LW100, the
addresses 29 and 30 are intended for the connection of the interface
and the computer modules. If these are not used additional
handhelds can be use these addresses.
To assign an X-Bus address to a specific device please refer to the
operating manuals for these devices.
The LH100 and LH200 handhelds operating as additional devices on
the X-Bus of SET-02, are what is referred to as a walk around
