KB963 Transponding With Other DCC systems

Will I be able to use Transponding with other DCC systems?Yes. You will have to run LocoNet, instrument your layout and install TL1 or TF4 or transponding decoders in your locomotives. You can then use a computer on LocoNet to display position and ID information for transponder equipped locos. LocoNet will run independently of your existing non-LocoNet system.

KB169 PR3 Operational Modes

What are the different operational modes available in the PR3? The PR3 is the combination of two previous Digitrax devices: the PR2 decoder programmer and the MS100 LocoNet to computer interface. The PR3 can be configured through manual (control panel buttons) or automatically (software) means to perform any one of the following three operations: a) The PR3 can be configured to function as a stand alone decoder programmer. In this mode the PR3 can program the configuration variables of most DCC decoders and the sound effects of the Digitrax Sound FX sound decoders. b) The PR3 can be configured to ...

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 ...

KB172 PR3 - General Applications

What are the most common applications for the PR3? 1) Stand alone Sound FX programmer As a bench tool the PR3 is the first USB and second device designed by Digitrax for the programming of the SoundFX sound decoder. The PR3 does write to and read from the sound patterns of any SoundFX sound decoder. In addition the PR3 can write to and read from any CV of most current non sound mobile and function decoders found in today's market place. 2) Digitrax command station LocoNet to Computer interface As a layout control tool the PR3 is a second generation ...

KB76 PR3 - Running with JMRI on Mac OS 10.5

Running the PR3 with JMRI on MAX OS 10.5 (Leopard) 1) Plug in the Digitrax PR3 to a USB port on an Intel-based Apple computer running MAC OS version 10.5. Within about a second the Green "USB" led on the PR3 should glow steady green showing a USB connection has been established with the MAC. 2) Open system profiler and under hardware>USB there should be a entry "Vcom" showing that the USB port has enumerated OK. This optional step is simply to check the PR3 device was found. 3) Go to JMRI sourceforge projects on the Web, here and follow ...

KB594 Is Digitrax signaling and detection equipment compatable with other DCC systems?

Q: I have a Lenz Set 100 and was wondering if I can use my DCC system and use the Digitrax signaling and detection components. What about other DCC systems?A: Yes, Digitrax detection and signaling will work with any DCC system.  You will need to install a LocoNet network for the LocoNet components to communicate with each other and use a PR3 or MS100 to interface with a computer running software such as Railroad and Co. 

KB483 Bushby Bit - Disable Normal Switch Commands

Q: What's a "Bushby bit"? A: In your command station, OpSw27 can be toggled to disable normal switch commands, a.k.a. the "Bushby bit." This allows the layout operator to use an attached PC to handle switch control logic. Under normal conditions, advanced throttles can be used to operate turnouts which are controlled by LocoNet-connected stationary decoders. The factory default setting for OpSw27 is "t". Toggling OpSw27 to "c" takes this control away from the individual throttles and gives it to a controlling computer. Such an application would be a railroad with CTC control, where the train movements are directed by ...

KB203 Case Study: Texas & Southwestern Part 11 of 11 - Future Expansion

As originally conceived, the Texas & Southwestern was set up with a very simple DCC system. The railroad uses a DCS50 Zephyr as its command station and booster. The Zephyr is connected to a central power bus, and all tracks, stationary turnout decoders and the automated reverse loop unit are connected to it. Likewise, the LocoNet connections are a series of simple cable connections starting at the Zephyr and ending at the last Universal Panel. The T&SW works well with this arrangement, but there are additional devices that will enhance the operation of this railroad. Digitrax PM42 Power Management System ...

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 ...

KB187 Case Study: PUTRA Computer Operation of the Kelana Jaya Rail Line Model (Part 5 of 5)

The Kelana Jaya Rail Line model layout uses WinLok 2.1 running on a PC under Windows 98 to operate the trains, turnouts, signals and to use the feedback from the block detectors for train control. This equipment was configured and programmed to PUTRA's specifications by Dr. Hans R. Tanner of DigiToys Systems. PUTRA specified the following capabilities for the control system used for the simulation: 1. Run eight trains at once in any combination of automated or manual control. 2. Define specific routings and be able to assign automatically or manually any route to any train at the time the ...

KB188 Case Study: PUTRA Operating the Kelana Jaya Rail Line (Part 4 of 5)
