Command Station or Booster Troubleshooting

If the DB200+ booster shuts down frequently: 1. Move the DB200+ so that the heat sink has a flow of cool air. 2. Place the DB200+ out of direct radiant heat like sunshine or a room heater. 3. Try direct cooling by using a small fan to blow cool air onto the heat sink. 4. Lower the track load current. 5. Reduce the input voltage from the transformer. If the DB200+ beeps 4 times and shuts down briefly and then comes back on again, it is probably being run too close to its pre-set current limit. To solve this problem, ...

There are times when it is necessary to reset the Super Empire Builder. Because this is a system reset, there are special instructions: There are different levels of system reset. OpSw 36: Clears all mobile decoder information, including locomotive consists. OpSw 38: Clears the locomotive roster (such as when you receive a "slot=max" error report). OpSw 39: Full reset, clears all internal memory states. The factory default setting for all DB150 option switches is t or "thrown" The Initial Procedure 1. Determine which DB150 option switch you want to change, 36, 38 or 39. 2. Move the Mode toggle switch on ...

The DB150 has many customizable system operation options that you can set. The DB150's power up defaults are fine for most applications and the DB150 will run just fine right out of the box. These options are provided for those individuals who want more flexibility in setting up their operations. The factory default setting for all DB150 option switches is t or thrown except for 5, 17, 25, 33 and 34 which are closed ("c"). Changing DB150 Option Switches 1. Consult DB150 Option Switch Table to determine which DB150 option switches you want to change. 2. Move the right toggle switch on the ...

If the DB150 beeps 5 times and shuts down briefly and then comes back on again. It is probably being run too close to its pre-set current limit. To solve this problem, reduce the track current load by setting up additional power districts to provide more total power for the layout. In this case excess current consumption may clip or mutilate some outgoing packets to keep the track current within acceptable limits.

Q:  I recently split my layout in half, with a DB150 acting as a booster powering one side and a DCS100 powering the other. I'm trying to reconnect the bus feeders to the rails, which all worked properly before the split. Now when I reconnect the feeders there is no short indication, BUT when a loco goes over the insulated gap between the two sections, a short occurs. A:  This is a common issue when the first booster is added to a DCS100/DCS200 command station. MOST DCS100/DCS200 command stations come from the factory set with Rail A & Rail B connections that are the opposite ...

Q: Can you have two command stations on the same layout? A: No. If you try and run with two command stations you will experience what we usually refer to as "shocking, horrifying results." Two command stations on a single layout is often a problem with modular layouts. You can disable the command station capability in Digitrax Command Station/Boosters so that you can use them as boosters only to add more power to your layout.For the DCS100 to disable command station mode:1. Set Op switch 2 to "c" 2. Set Op switch 5 to "t" 3. Set it to auto ...

A slot is a memory location in the command station that holds an active decoder address.  The number of slots is the number of locomotives that the command station can support in operation at a time. When the available slots are filled with decoder addresses, trying to select another locomotive address to run generates the "slot=max" error code.  When all the slots are full you can't select another address until one is released from the system. See Clearing your Command Station's Mobile Decoder Slots below for how to prevent this from happening.The DCS100 Command Station/Booster that is included with Super Chief Xtra and other ...

If the Zephyr DCS50 repeatedly shuts down briefly and then comes back on again, it is probably being run too close to its pre-set current limit of 2.5 Amps or it may be overheating due to restricted air flow to the bottom of the unit. In this case it may clip or mutilate some outgoing packets of information to keep the track current within acceptable limits.To solve this problem, reduce the track current load by running fewer locomotives or setting up additional power districts and adding more boosters to provide more power for the layout.  With more sound decoder equipped ...

LocoNet is Digitrax's method of communication between LocoNet compatible devices on a model railroad layout.  LocoNet compatible devices are designed to work together on the network, and in some cases can also accept DCC commands from  the track, but often go beyond the scope of simple DCC train control.   LocoNet is a peer-to-peer Ethernet type multiple access network.  Because of its design architecture, it is very robust and powerful.  Layout implementation is simple and wiring is free form with minimal limits. LocoNet is designed to run an unshielded 6 conductor ribbon cable.  Digitrax recommends using flat, six-conductor telephone wire ...

When you hear 7 beeps when power is applied to your DCS100, you need to replace the CMOS battery. The DCS100 will continue to operate, even if this battery is not present, but all your memory settings and option switch settings will not be remembered when the DCS100 is powered down. To replace the CMOS battery without losing any memory settings: 1. Remove the DCS100 input power & disconnect all DCS100 leads. 2. Open the DCS100 case:  a. Remove the two screws on the top and bottom of each side of the case. b. Slide the gray front panel off ...

The NET indicator is a red LED that displays information about what the DCS100 sees on LocoNet. When your layout is wired correctly and LocoNet is operating properly, the NET indicator will be on and it will flicker off any time a good LocoNet message is detected by the DCS100. The table below explains the patterns you will see for this indicator.

  To reset the DCS51/DCS50 to factory settings: If you change command station option switches and experience unexpected results, just set OpSw 39 to “c” (closed) to reset the unit to the original factory settings. 1. Press the PROG key. The display shows the last decoder programming mode used. 2. Press the SWITCH key. The display shows the last switch used and its commanded position. 3. Use the numeric keypad to enter the number of the Option Switch you want to change; in this case 39. 4. Press the "c - / CV-WR (lower right of keypad)" key to set the ...

When using a DCS100 or DCS200 to setup routes within the Command Station in conjunction with DS64 Stationary Decoders, the DS64 needs to be connected to Track Power. The DCS100/200 does not send internal route messages via LocoNet. DCS100/200s only send Routes as a series of switch commands out to the Track in DCC format.  The DSC100/200 were designed in 1996 and had no requirement to echo these same switch commands out via LocoNet.  Additionally, DS64 Stationary Decoders are designed to allow up to 8 Routes to be programmed internally into them. Please refer to the DS64 manual and other ...

From the start, the Texas & Southwestern was built with DCC in mind. The T&SW was built from the ground up by an individual with considerable model railroad experience, but an issue arose that defied explanation. The T&SW was meant to be operated with a DCS50 Zephyr, and the layout support structure was enlarged slightly to fit the Zephyr into one corner of the railroad. As it turned out, the cozy corner space for the Zephyr turned out later to be a bit too cozy. The bottom of the Zephyr has ventilating slots to help cool the unit’s electronics. As ...

Digitrax command stations have Option Switches that care used to customize their operation.  Command Station option switches should not be changed unless you fully understand what you are trying to accomplish.  Information on these Option Switches is included in each command station's manual.Be sure that you are changing the correct Command Station Option Switches as the unit can be crippled by closing the wrong switches.  NEVER CLOSE OPTION SWITCH #1!!Clearing your Command Station's Mobile Decoder SlotsMost command station problems are caused by filling up the command station's available slots by the following:1.  Operators failing to zero the speed of unused ...

Before sending your Digitrax Command Station or Booster in for repair try these simple steps to see if you can “bring it back from the dead” and save a possible trip to the repair shop.1. Nothing is respondingIf there are NO LEDs lit on the front panel of the Command Station or Booster: Check the power supply to the unit to make sure that it has not been knocked loose in the power socket and that the socket is powered. Check the connections from the power supply to Track A and Track B connections on the front of the unit ...

What does SLP mean on the DCS50? The "slp" message on the DCS50 means that the unit thinks it is temporarily in sleep mode. This may occur if the LocoNet data line is grounded for more than 1/8 of a second. You may initially try to exit Sleep Mode by cycling the "Exit" key on the DCS50, or powering down and repowering the unit. If this problem continues, you must check your LocoNet for a shorted connection.

The front panel of the DB150 Super Empire Builder has electrical connection points, indicator lamps, LocoNet connections and toggle switches which give status indications, configure and connect the unit for your railroad. Power Input The two “POWER IN” terminals on all Digitrax boosters & command stations are the power input connections. Please see the related articles about power requirements for the DB150. Power Supply Digitrax recommends the PS515 power supply to power the DB150. There are many other transformers and power packs that can supply the input power for the DB150. Check with your Digitrax dealer for suggestions. Most regular ...

If the DB150 unit shuts down occasionally due to a track short circuit: 1. Correct the short circuit condition and the booster will resume normal operation. 2. Turning off the booster when a short occurs is not necessary since it will re-start automatically when the short is cleared. If the DB150 unit shuts down frequently: 1. Move the DB150 so that the heat sink has a flow of cool air. 2. Place the DB150 out of direct radiant heat like sunshine or a room heater. 3. Try direct cooling by using a small fan to blow air onto the heat ...

What is the difference between boosters and power management? A Booster is the device that provides the electrical power to the railroad. Most Digitrax command stations have a combined booster. The command station generates the DCC signal then sends it through a booster to the layout. A small model railroad may only have the command station and booster, while a large railroad will have numerous boosters. Multiple boosters provide more power to larger layouts.Additional boosters receive the DCC signal from the command station via LocoNet. Power management usually refers to the devices which act as circuit breakers and power distributors. ...

Direct Home Wiring: A wiring system where the DCC booster powers each rail via an individual wire.  Each booster is wired to it's own track power section and there is no electrical connection between boosters. This means that each power district is double gapped and is connected to it's own booster.  The boosters are in turn connected via LocoNet to the command station providing one source of commands for the entire layout.Digitrax recommends using only Direct Home Wiring for all Digitrax layouts. Non command control layouts typically use common rail wiring as part of their control method. This means that one rail ...
