DIGITAL plus
In order to prevent the digital operation from being influenced by the
normal DC and vice versa, when a sectioning gap is being driven
over, install the sectioning module LT100.
At the gap dividing digital from analog operation, you must take
steps to prevent interference between the 2 systems when a
locomotive crosses the gap. One approach is to use a Digital Circuit
Breaker such as the LT100. If a locomotive bridges the insulated
gap, the module immediately interrupts the analog power supply.
Warning
:
Mixed digital/analog operations using both rails and catenary
(overhead wire) is not allowed. In this mode of operation, if the
locomotive is on the track in the wrong direction (for instance after
going through a loop), the built-in locomotive decoder could be
destroyed by excessive voltage! We suggest you operate with
current pickup from the rails (wheel pickups), since that contact is
more reliable (and thereby the transmission of the digital signals to
the locomotive decoder) than with catenary.
15.7 Wiring the X-Bus
The X-Bus data network consists of 4 wires, 2 are for the signal and
two are for power that is used to power plugged in X-Bus devices.
To install an X-Bus for SET-02 you need to insert an LA152 between
the LH200 command station and the LV200 power station. The 4
terminals on the LA152 labelled. L,M,A and B are the 4 connections
for the X-Bus. Connect these 4 wires to the terminals with the same
name on the LA150 connection board.
You can also solder the 4 wires to the DIN-sockets yourself. These
sockets are available in electronic-shops or in groups of five as part
XP-5 . The assignment of the five-pin DIN-socket is shown in the
following figure:
