DCS51 & DCS50 Command Station/Booster/Throttle

Q:  Can I add a booster to my Zephyr? A:  Yes. Since the DCS51 Zephyr Xtra and DCS50 Zephyr are equipped with LocoNet, adding additional boosters is easy; you simply divide your railroad up into power districts and add the boosters and their individual power supplies. These are connected together using LocoNet cables. Because the Zephyr Xtra is rated at 3 amps and the Zephyr is rated at 2.5 amps: most boosters have higher ratings, you may want to have the Zephyr control a smaller area that has fewer power consumers (locomotives, lighted passenger cars), such as a main line ...

Q:  I have an MRC RailPower 1370 DC power pack.  I was wondering if that would work as a jump throttle on my Zephyr till I get my UT4 LocoNet Throttle? A:  We think that the answer is "No", but you will need to verify whether this power pack produces pure or pulsed DC power directly with MRC. Throttles used with Zephyr Xtra via the Jump Port must produce pure DC power, often referred to as "smooth" power packs. Many "advanced" analog power packs use automatic pulse injection to make model locomotives run better at slow speeds. This uses 1/2 wave AC ...

  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 ...

  How do I program the PM42 Op Switches with a DCS50 (Zephyr) throttle? The PM42 OpSw settings are used to set up the PM42, adjusting the trip current, short circuit management (including sensitivity), and/or auto-reversing. Note: The factory default setting on all PM42 OpSw's is “thrown” or “t”. Follow the steps outlined below to program the OpSw settings of the PM42 using the keypad of a Digitrax Zephyr. 1. Connect the PM42 to the Digitrax Zephyr with a standard LocoNet cable. 2. Connect the PM42 to an external power source; Digitrax recommends the PS14. Note: Before entering Switch Mode ...

The DT402 & DT400 can program and readback CVs with the DCS100 or DCS200 (Super Chief) or the DCS51 or DCS50 (Zephyr). You must use the programming track for this unless you are using Ops Mode with transponding installed to allow for Ops Mode readback.  Infrared and simplex radio throttles must be plugged in to LocoNet to read back CVs & their values.  Duplex radio throttles do not have to be plugged in for reading back CVs.Systems with a DB150 command station (Super Empire Builder) are not able to read back CV Values programmed into decoders. To read back CV values: 1. Place the decoder ...

PM42 Short Circuit/Auto-Reversing Failure When used with Zephyr (DCS50) The PM42 is designed to control 4 independent power subdistricts that can be set up as either a “Short Circuit Manager” (the factory setting) or as an “Auto-Reversing Controller.” The PM42 factory setting for trip current is 3 amps. The trip current can be modified to settings from 1.5 amps – 12 amps to accommodate the needs of your system. In addition, each of the 4 power subdistricts can be set for slow, regular, faster or fastest short circuit management. While a trip current of 3 amps will work with most ...

I have a Zephyr and a DB150. How can I wire the two together so that the Zephyr acts as throttle and the DB150 supplies power? At this this time I have only a single block. The easiest way to handle this situation is to divide the railroad up into two power districts. If one command station unit is more powerful than the other, then the area controlled by the weaker unit (in this case, the 2.5 Amp Zephyr) could simply be a single siding or engine terminal. The Zephyr would then become a booster, supplying power to this small ...

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 ...

If a Zephyr has been switched to run as a booster/throttle (no command function), can it still be used to program locomotives on the programming track? No, when using the DCS50 as a booster, the programming outputs are disabled. Programming is a function of the command station only, so when the Zephyr is toggled to booster mode, it loses the programming function. If a Zephyr has been switched to run as a booster, does the throttle still work? Yes, but you must assign an unique throttle ID to the Zephyr which is acting as a booster. Assigning Throttle Identities To ...

Q:  I'm wanting to know how to MU two locomotives together that are in a tail to tail configuration. I know that this can be easily done with a DT400 or DT402 throttle but not sure how to do it with the Zephyr. A:  Make sure all the locos in the consist are traveling in the same physical direction on the track (both going to the left or to the right). Remember that "reversing" takes place in the locomotive not on the track, so it is important that the engines be traveling in the same direction when they are MU'd.  ...

I'm helping a friend rewire an existing layout from analog to digital. You might be familiar with the layout, it is the original Clinchfield layout that Model Railroader built back in the late seventies, believe it or not. The layout, of course, is blocked for analog through DPDT switches which have been eliminated. I was able to repair the wiring back to original using the drawings that MR printed. The layout uses common rail wiring, this is what I have to work with, and to rewire using home run wiring would be a MAJOR rework, not doable. I was able ...

What happens when I select a loco that is currently running at a different speed than the throttle is set to? example... running loco 'a' at half speed then switch to loco 'b' does loco 'b' suddenly change speed to half throttle? (which is the last position the knob was indicating for loco 'a' this would make for a nice crash if I planned on backing loco 'b' out of a siding, and it goes forward instead at 50% right into a bumper) You're right, when switching the loco 'b', the newly selected locomotive would be commanded to operate at ...
