  Q: How can I configure the DS54 for block occupancy detection? A:  Any DS54 input can serve as a block occupancy message generator. All that is necessary is to activate a DS54 input with a device that can detect the presence of a train within a specific area/location. The DS54 input can respond to a number of different block occupancy devices including the BD1, BD4, and isolated contacts. The following drawings indicate two different methods (wiring schematics) for the connection of devices to the DS54. The upper drawing Is for isolated contacts and the lower drawing is for BD1 ...

Q:  How can the DS54 be configured to control a Flashing Crossing Signal? A:  The elements necessary to create a simple function flashing/blinking crossing signal are: a block occupancy detection (trigger) device, an electronic flashing/blinking circuit (DS54) and a crossing signal. The DS54 can accommodate two different types of triggering devices: Digitrax block occupancy devices (BD1 and BD4) and third party block occupancy devices (such as magnets and reed contacts). The following drawings indicate how to connect the two different types of triggering devices, along with the crossing signal, to the DS54. The upper drawing is for the BD1 or ...

Q:  What is the procedure for programming the DS54 Address using the Programming Address Button? A:  The procedure for programming the DS54 address using the Address Programming Button is simple. This procedure only requires the determination of the turnout addresses block for the DS54. During the programming cycle the activation of any turnout address within the desired turnout address block will automatically set the DS54 to the proper module address. 

Q:  What is the purpose of the Program Enable Link? A:  The CV Program Enable Link is used to program the DS54. The link (two pins) must be in the open position (one pin uncovered) for normal DS54 operation. The link (two pins) must be in the closed position (both pins shorted by the shorting block) during the programming of the DS54. Warning: The DS54 will behave erratically if the link is closed during normal operation.

Q: I am setting up a yard control panel with a CML Electronics DTM30. For the DTM30 to know what state a turnout is in, it can issue an interrogate command but my DS54's do not seem to respond with this information. Is there a trick to this? A:  According to CML: The DTM30 makes use of the “Interrogate” feature that all modern Digitrax systems use. After power up, the Command station normally sends out 8 switch commands. All accessory devices respond to these, and send LocoNet messages back reporting sensor states and point states. The DTM30 can also send ...

  There are two methods of providing power to the DS54: from the rails and from an auxiliary power source. The DS54 can be powered from the rails however, Digitrax strongly recommens that the DS54 be powered from an auxiliary power supply capable of delivering 12-16 volts (ac or dc) at 300 millamperes for best results.  Powering the DS54 from the rails reduces the current available to power locomotives and lighted rolling stock.  The auxiliary power supply connections are the red (+) and black (-) wires. Note: Digitrax recommends the PS14 Power Supply for independently powered DS54’s. Multiple DS54’s can be powered from a single power ...

Q:  Can I set up the DS54 to act as an emergnecy stop device? A:  Any unused DS54 input can be configured to send an Emergency (OPC_IDLE) Stop packet. The typical Emergency Stop circuit is a supervised series of one, or more, normally closed switches or contacts. When any one of these devices is opened the circuit is deactivated and everything affected by the Emergency Stop circuit immediately shuts down. The following drawing depicts a typical Emergency Stop circuit using a DS54. 

Q:  How do I reset the DS54 CV's to factory default values? A:  Each DS54 CV must be manually reconfigured to set the DS54 to factory default values. The factory default values for the DS54's CVs are: CV01 = 1 All other programmable CVs = 0

  How to Configure the DS54 for one-button turnout controlThe local buttons, throttle, or any other turnout control device connected to the LocoNet can control the DS54 output when the DS54 is connected to the rails. The following drawings indicate the general wiring schematic for a one-button control of a turnout using either a Dual Coil (upper) or slow motion (lower) switch machine. The following two charts indicate operating criteria and CV settings for one-button turnout control. 

The DS54 is a powerful stationary decoder, which can be used to control devices in several different ways. Within the DS54 electronics are four independent sections. Within each section are three independent elements: Switch_, Aux_ and Output_. Each element can act independently or in conjunction with one or more elements within that independent section. (Note: The Switch_ element can be accessed from the input connector and the Output connector of the respective section.) Each of these elements can perform any one of several different actions. The actions are determined by two variables: trigger and task. The relationship of the Trigger ...

  Setting up DS54 for Exact Turnout Reporting The creation of a feedback circuit for exact turnout reporting is simple. Connect a normally open set of contacts attached to the switch machine, a normally open set of contacts of a micro switch monitoring the throw arm, or a normally set of contacts of a relay monitoring the switch machine power to the common and switch input of the DS54 input connector. When the turnout is closed these contacts must be closed. Connect a normally open set of contacts attached to the switch machine, a normally open set of contacts of a ...

  Setting up DS54 for Standard Turnout Reporting The creation of a feedback circuit for standard turnout reporting is simple. Connect a normally open set of contracts attached to the switch machine, a normally open set of contacts of a micro switch monitoring the turnout throw arm, or the normally open contacts of a relay monitoring the switch machine to the common (green) and switch (red) wires to the desired DS54 output circuit. The following two diagrams indicated the two most common switch machine configurations plus the contact configuration for turnout reporting.  Note: The location and type of contacts available for ...

  How do I connect the BD4 to the DS54? The BD4 is a block occupancy detection device designed as an add-on device that can take advantage of the LocoNet hosting capability of the DS54 stationary decoder. It is connected in this way: The installation of a BD4 is relatively simple. Looking at the BD4, you will find a 5-point terminal block on one end and two (LED1 and DS1) 10-pin (5x2) headers on the other. There are three termination areas: a) The 5-point terminal block (left) is for the interconnection between the rail power source and the rails. b) ...

Q:  Can I set up the DS54 for two-button operation turnout control? A:  Two-button control (one button for setting the points to the main route and the other button for setting the points to the diverging route) is a standard configuration for the control of any turnout.  The following charts indicate operating criteria and CV settings. 

Q:  What is the purpose of the single 6-32 screw terminal beside the input connector? A:  The 6-32 screw terminal next to the input connector is the -VE Sensor common for the BD1 and BD4 block occupancy detectors. The 6-32 screw terminal next to the input connector should not be mistaken for the standard system ground. The LocoNet connector handles all of the DS54’s system ground needs. Warning: Do Not Connect the 6-32 screw terminal to a house or earth ground (water pipe, electrical ground connection, earth ground stake, etc.) as it may result in damage to the DS54.

Connecting BD1 to a DS54, DS64 and SE8c? The BD1, block occupancy detector (replaced in 2004 by the BD4) was designed as an add-on device, which took advantage of the block occupancy message generating (over the LocoNet) capabilities of the DS54. The BD1 is also compatible, for the same purpose, with the DS64 and SE8c. The following diagrams indicated how to connect the BD1 to the rails, rail power source, and the Digitrax DS54, DS64 and SE8c.  Note: The wires that connect the BD1 to the rails and rail power source are characterized as two heavy, uninsulated, and polarity neutral wires.

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 ...

Over the years, different Digitrax throttles have used a combination of decimal, modified hexadecimal and hexadecimal numbers for entering CV numbers and CV values.  The following information is provided as a programming reference to show you how these different schemes work so that you will be able to use your throttle to program decoders.UT1 & UT2 Utility Throttles use decimal numbers exclusively for CV numbers and CV values.  Because these throttles use 2 selector switches that can access the numbers 0-9, you are limited to programming only CV#s and values from 00 to 99.DT100 Throttles use a modified hex numbering ...

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 ...

The layout uses twenty-eight turnouts on the mainline and an additional eleven turnouts in the yard. Each turnout is powered by a Tortoise slow motion turnout motor. Each of the twenty-eight mainline turnouts has three dwarf signals associated with it. The aspects of the signals are shown below. The indications of the signals are: Green = Proceed Yellow = Proceed with caution Red = Stop Each signal has one head with two LEDs. There are also thirty-eight mainline block signals (red/green) that are controlled by heavy duty single pole double throw relays. This makes a total of 122 signals. Since ...
