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.
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 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: 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: 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: 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.
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: 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
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 ...
The changing of the value in the CV of a DS54 is relatively easy if you follow the steps listed below. The difficult part is deciding which CV and CV value to program to achieve the desired effect. The following are step-by-step instructions for changing a DS54 configuration variable using a DT300 throttle: 1) Disconnect the DS54 from LocoNet, the auxiliary power supply, all inputs and all outputs. 2) Short the pins of the Enable Link. (see related article) 3) Connect the DS54 track inputs to the command station programming track. 4) Connect the yellow feedback adapter wire from any DS54 output (A, ...
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 ...
I own a Digitrax Starter Set that is now discontinued. Can I still use it and can it be upgraded?LocoNet lets you use all Digitrax LocoNet components in your system no matter when you purchased them. You can continue to use what you already own with new components as they become available. Note: This will work with all starter sets except for Challenger. If you have a Challenger Set and you want to move up, the best thing to do is to purchase one of the new sets and use the DB100 series booster that came with your Challenger as ...
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 ...
