This product is for layout using Lenz Gold and Silver Decoders only

This Asymmetric DCC compatible BitSwitch can be used as a Stand Alone device
to maintain separation between two trains on the same line or in series to
automate a large loop for any number of trains.

NO BRAKE GENERATOR BitSwitch IS NEEDED WITH THIS BitSwitch
However if this switch is combined with other standard
BitSwitches an Asymmetric Brake Generator BitSwitch is required

Asymmetric Block BitSwitch
$39.95

This simple device is connected to 2 track sensors and an isolated section
of "The Right Rail" in the direction of travel.

The terminal connections are
R= Release Braking
B= Set Braking
C= R/B Common
O= Right Rail Track Power
L= DCC input from the Hot (continuous rail) LEFT RAIL
X= DCC input from the opposite rail RIGHT RAIL

EXAMPLE FOR CONTROLLED SPACING ONE BLOCK
No separate Asymmetric generator required

When multiple blocks are combined for total automation applications
the following products are more cost effective
This scheme allows for automatic control to be turned on or off for
all braking sections with one toggle switch.
This simplifies control of the layout

Asymmetric DCC Generator
$25.00

Asymmetric Block BitSwitch
$25.00

When the Asymmetric Generator BitSwitch is in the ON position trains will be slowed to a stop if the next one block forward
is occupied and will accelerate to its original speed setting when the forward train reaches the track
contact two contacts forward.

The Lenz Asymmetric decoders allow for "EXACT" stopping Distance to align with a Station
Platform or loading dock

When the trains are stopped they can still receive all commands from the DCC throttle EXCEPT
changes in speed steps.

When the BitSwitch Toggle is in the OFF position the automatic controls are disabled

Asymmetric ABC Circuit for Lenz and Zemo

Automatic reversing for Push Pull operation on Spurs or intermediate stops now available with Lenz Gold or Silver series decoders

For Push Pull gap the Right Rail at each end and install BitSwitch Circuit

For intermediate stops in one direction the gap rail is always the RIGHT rail.
The engines will stop in sections getting the Asymmetric DCC feed.

See your Lenz or Zimo manuals for appropriate Decoder CV settings

CV settings allow for duration of stop time, momentum, distance to stop
and reverse option for push pull if desired.
