KB394 DS64 - Cascaded Routes Example

A cascaded route is where the last command of a route triggers the next route; this is also known to some as a nesting route. With the capacity of 8 turnouts per route, it becomes necessary to cascade routes if more than 8 turnouts are involved in a route. To highlight these possibilities, we use a very complex scenario with many turnouts and possible routes. Cascading routes allows the setup of long routes without the need for a computer. Since some routes exceed the capacity of 8 turnouts, the remaining turnouts of the long routes are setup in the second ...

KB613 Throttle Jacks vs. LocoNet Jacks

The jacks on the front and sides of the UP5, UR92, UR91, UR90, and LNRP front panels are Throttle Jacks and should only be used for connecting throttles to LocoNet.  They should not be used to connect to other LocoNet devices.  The jacks on the back of these units are LocoNet Jacks that are used for connecting LocoNet devices to the network.  Technically speaking! These units were designed to have the FRONT jack's second Railsync differential signal run as a diode-or'ed power source (for throttles).  This means that some cable orientations and power loads could cause unexpected operations in downstream LocoNet devices ...

KB126 Kato Unitrack Turnout Control

I have installed 381-2503 KATO DC turnout machines in the turnouts on my layout and want to move to DCC operation using a Digitrax 245-DS51K1 stationary decoder. Will I have to change my switch machines to #245-DS61K1L DCC machines to do this or stay with the same DC machines? You do not need to change out the turnout motor. The DS51K1 decoder is meant to control Kato UniTrack bi-polar switch machines for both the N-Scale and H0-Scale Unitrack product lines, such as the 381-2503. You can also control these switch machines with the DS64, in groups of up to four. ...

KB599 Can AR1 be used to set up automatic back and forth operation?

Q: I am building a new DCC layout that will include a logging spur that is simply a single long piece of track with no loop. I want to have a train go back and forth on this track which automatically reverses when it gets to each end. While the AR1 was designed for reversing loops, can it be wired to simply reverse a train on a straight piece of track? A:  Not in the way that you intend. One of the interesting problems with DCC is that we often still think in terms of DC, where the track polarity ...

KB171 PR3 - Stand Alone LocoNet Interface Applications

Under what conditions can the PR3 be used as a Stand Alone LocoNet Terminator? The PR3 is so designed so that it can be configured to act as a stand alone LocoNet controller in the event that a Digitrax command station is unavailable for the control of a series of LocoNet compatible devices. There are two major situations that would require the PR3 to act as a stand alone LocoNet controller. The first situation is where one of the many advanced features offered by the LocoNet and the various LocoNet compatible devices is desired to be used on a layout ...

KB828 Zephyr - Switch Mode

Switch Mode is used for sending commands to accessory decoders and for changing Option Switches (OpSw) in your DCS50. The most common use of switch mode is for operating turnouts (track switches).To change the position of a turnout:This note assumes that you have already installed and programmed turnouts and turnout decoders on your layout.  Each turnout is connected to a stationary decoder that controls the operation of that turnout.  There are several different stationary decoders for this purpose such as DS64 and others.  Please see the related articles below.1. Press the SWITCH Key. 2. The last switch address selected by ...

KB117 Notes on Kato HO-Scale Unitrack Turnouts

Kato recommends, and Digitrax concurs, that the best DCC performance with the Unitrack turnout requires that you set each turnout to "Non-power-routing". Kato has offered a variety of turnouts in their H0 Unitrack line.381-2840 - LH, 490mm Radius, selectable operating mode with power or non-power routing.381-2841 - RH  490mm Radius, selectable operating mode with power or non-power routing.381-2850 - LH, #4, power routing only.381-2851 - RH, #4, power routing only.381-2860 - LH, #6, live or insulated frogs, power or non-power routing. 381-2861 - RH, #6, live or insulated frogs, power or non-power routing. These model numbers are current as of ...

KB189 Case Study: PUTRA Powering the Kelana Jaya Rail Line (Part 3 of 5)

The Kelana Jaya Rail Line model is a DCC intense layout, using many Digitrax command control components to achieve the goal of training operators of the actual rail line. The railroad was built in the 1990's and many of the Digitrax devices used for the Kelana Jaya Rail Line model have been superseded with improved units. Components used for the Kelana Jaya layout: 28 Mainline turnouts 11 Yard turnouts 39 Tortoise switch machines 84 Dwarf signals (yellow/green, red/green, red/yellow) 38 Mainline block signals 38 Heavy duty SPDT switch relays Digitrax Components Used for the Kelana Jaya layout: 1 DCS 100 ...

KB7 Automatic Reversing Sections

DCC Automatic Reversing SectionsVirtually all automatic reversing will fall into 3 categories with the wiring principles for all being the same:1. Reverse Loops2. Wyes3. TurntablesDCC has the ability to automatically reverse sections of track we call Reversing Sections while our trains are running and not affect the direction or speed of the trains. This is because we put a constant square wave AC current on the track and control the trains (locos) by sending messages to them (actually to receivers we call decoders) to tell them what to do such as start, stop, change directions, etc. . We are thus ...

KB14 Switching Layout Examples

At first glance, the typical switching railroad would not seem to be a good candidate for DCC operations. Yes, there may be only one locomotive on many of these railroads, but that locomotive can still benefit from DCC. By adjusting the starting, mid-range and maximum speed values of this locomotive, you get very good slow speed control, perfect for the switching railroad. And, of course, if you add a second locomotive, then DCC becomes the clear choice because you are not longer having to throw toggle switches just to move around the yard. The DCC environment also gives you turnout ...

KB127 Slip Switches

The slip switch is a track element that has both a crossing at grade and also a set of movable points which allow trains to both cross another track and also change track.  The Crossing The crossing allows tracks to cross each other at grade.  The Slip SwitchThe more complex slip switch allows trains to both cross and to change tracks: In the schematic below, you will note that the slip switch is more compact than ordinary turnouts.  As a result, they are often found in high track density areas such as passenger terminals, where space is at a premium. ...

KB313 250 Square Feet Layout

  I have an "M" shaped 250 square foot layout with 500 feet of track and twelve locomotives. What Digitrax equipment would I need? You don't say what scale this railroad will be modeled in, which is important since the locomotives in smaller scales draw less current than larger decoders. However, for purposes of estimation: Twelve Locomotives. Each locomotive is going to draw, at the very least, 5 MA for the decoder. If it has LED lights, then it will typically draw 15 MA more; conventional light bulbs will draw 50 MA. A typical H0 locomotive will draw 600 MA ...
