Adding duplex radio, infrared or simplex radio to your existing Digitrax system is simple because of LocoNet.InfraRedYou probably already own a DT300, DT400, UT4 or DT402 series throttle. All of these are "InfraReady." These all come with two IR emitters pre-installed. All you have to add for IR operation is one or more UR90 Infrared Receivers to your layout. Most layouts require multiple UR90s because the infrared signal is line of sight. This means that your receiver will need a sight path to the throttles.Simplex RadioDigitrax throttles with an "R" at the end of the part number are simplex radio ...

The MS100 LocoNet Interface is a serial device that connects LocoNet to a computer via a 25pin serial port.This application note shows how you can use your Digitrax MS100 computer interface with the USB Port on your computer.  Serial ports are not available on most computers in current production. USB ports are more widely used today.  The Digitrax MS100 LocoNet interface can be connected to a USB port by using a USB to Serial RS-232 DB-25 Adapter Cable.  Digitrax recommends the PR3 for interfacing your USB equipped computer with LocoNet.Caution: Not all cables on the market will work. One that ...

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 ...

LocoNet System ArchitectureDigitrax LocoNet is a Peer to Peer local area network (LAN) designed specifically for model railroad operation.  System architecture is the biggest difference among DCC systems, the way the components of a DCC system communicate among themselves. LocoNet wiring is cost effective, flexible and expandable to accommodate almost anything you want to do with your railroad today and in the future.System ExpansionHere are some of the expansion possibilities available with LocoNet. With Digitrax LocoNet your DCC journey starts at the Main Station with your first “starter” set. From there, it’s up to you. You can add:  Mobile decoders ...

To Test LocoNet Cables With an LT11. Unplug the wire harness from the LT1.2. Plug one end of the LocoNet cable you want to test into the LT1.Note: When making your own LocoNet Cables, it is important to make them in a consistent manner. At Digitrax, the white wire is always on the right side of the plug when the plug is viewed with the clip at the top.3. Connect the other end of the LocoNet Cable being tested to any powered Digitrax Booster’s LocoNet Port A or B. Be sure you have at least one Digitrax throttle plugged in ...

Railroad & Co. is a suite of computer programs for both digitally and conventionally controlled model railroads. The BDL168 needs to have several Option Switches changed for proper operation with Railroad & Co.'s Train Controller program. Our recommendations are based upon experience with earlier versions of the program: Suggested BDL168 Settings for Railroad & Co. (from European users): OpSw9 = Closed (No message sent if un-powered) OpSw36 = Closed (Ignore GPON) OpSw37 = Closed (Long delays for sensors) OpSw38 = Closed (Extra long delay for sensors) OpSw39 = Closed (Verbose mode enabled) OpSw43 = Closed (Filter for transponding disabled) OpSw45 ...

1. Disconnect the wire harness from the LT1.2. Plug one end of the LocoNet cable being tested into the LT1.3. Connect the other end to the cable into on of the LocoNet ports on your DCS50. Make sure the Track Status Indicator Dot is lit.4. All four LEDs on the LT1 will light if the cable is good. LEDs may not all be the same brightness, this is normal. NOTE: Only three LEDs will light if the Track Status Indicator Dot is not lit.5. If any of the LEDs fail to light, recrimp the plugs on the LocoNet cable and ...

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 ...

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 ...

1. The UP5 Universal Panel is designed for mounting on the fascia board of the layout. Cut a hole approximately 2.5” W x 1.5” H in the fascia board. Insert the UP5 through the hole with the face plate on the front of the fascia board. Attach the UP5 face plate to the fascia board with four #6 screws. Note: The UP5 uses the black screws to mount the front fascia plate.2. Connect the UP5 to LocoNet using pre-tested LocoNet cables. There are 2 LocoNet Jacks located at the back of the UP5 board for connecting LocoNet devices on your layout. ...

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.

I understand that LocoNet is used for transponding "feedback."  How can Digitrax systems handle both DCC and transponding without interfering with other track level communication and without adding another communication or feedback bus like other system have to do?LocoNet is a true network with future expandability built in. Part of that future is here now with transponding. LocoNet was engineered from the very beginning with things like this in mind.If you are already using Digitrax LocoNet, you will not have to add a "feedback bus" since this is already incorporated into LocoNet's design! If you are using transponding with a ...

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 ...

LocoNet's "ethernet like" architecture seems interesting and more advanced than the systems used by other DCC manufacturers. But, at the numbers we are talking about (a few controllers and perhaps 10-20 decoders), does it really make a difference?If your system operates with a few throttles and other devices attached any of the commercially available systems will work today. But what about tomorrow? Remember when a hard-drive bigger than 32Mb seemed excessive- and remember when DOS had to change to 16bit FATs/ directories? Also, the LBA access change at 540Mb also once seemed unthinkable!!The network structure of LocoNet is very important ...

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 ...

This section discusses the installation of the physical wiring of the Texas & Southwestern. Underneath the completed Texas & Southwestern are various wires and cables which allow you to operate your railroad. Initially, seeing all these wires can be intimidating, but as you will note, they have been grouped and bundled so that identifying the individual wires is easy. There are two groups of wires under the railroad; one group, the power bus, delivers power to the tracks and to the stationary decoders that operate the track switches. The other group of wires is the black cable for LocoNet and ...

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. 

The first Digitrax system to use LocoNet was Big Boy. Each Big Boy system came with a LocoNet Adapter 1 (LA1) or LocoNet Adapter 2 (LA2). Documentation for these units was minimal, but is included here. LA1 LA-1 came with a simple card: LA-1 LocoNet Adapter Use this cable to connect your DB100 to your DT200 command station unit and to your LocoNet command bus. The LA-1 allows you to connect more than one throttle to your Big Boy System. You only need one LA-1 in a Big Boy System. If you are upgrading to Big Boy from Challenger, you ...

Digital Command Control (DCC) has specific electrical requirements that must be provided for your layout control system to operate properly.Input PowerAll DCC systems require an external power supply.  Digitrax manufactures several power supplies for our command stations and boosters: The 3 Amp PS415 (the Zephyr Xtra power supply) The 5 Amp PS515 for all Digitrax 5 amp command stations and boosters The powerful 20 Amp PS2012 can be used for multiple 5 and 8 amp command stations and boosters  Additionally, the PS14 is available to power various other devices for your railroad.  Digitrax strongly encourages you to use our power supplies to insure satisfactory ...

The jacks on the front and sides of the UP5, UR92, UR91, UR90, and LNRP front panels are Throttle Jacks and should only be used for connecting throttles to LocoNet.  They should not be used to connect to other LocoNet devices.  The jacks on the back of these units are LocoNet Jacks that are used for connecting LocoNet devices to the network.  Technically speaking! These units were designed to have the FRONT jack's second Railsync differential signal run as a diode-or'ed power source (for throttles).  This means that some cable orientations and power loads could cause unexpected operations in downstream LocoNet devices ...

LocoNet is a peer-to-peer local area network, a communication network that is similar to communication networks used in today’s computer industry. There are five types of computer network topologies: star, bus, tree, freeform and ring.  The only prohibited configuration for LocoNet is the ring.  LocoNet should never be looped back on itself.Note: In the diagrams below, CS represents a Digitrax Command Station and the M represents any LocoNet compatible module or device.1.  The Star Topology is where all devices are connected to a central hub by individual legs. 2.  The Bus (Daisy Chain) Topology is where all devices are connected to ...

Q:  I just purchased a used Digitrax set consisting of a DB150, UT2 and a PS515 for a very low price. What do I need to add to bring this up to current standards? A:  Because of Digitrax LocoNet, it is easy to add the latest components to upgrade on older starter set.  What you purchased was originally called a Genesis Starter Set.  The PS515 did not come with it but it is the perfect power supply for the DB150.   Your next step depends on what you want to do with your railroad.  In this case, the components you have will be ...

Q:  Can I loop LocoNet?  Is there any benefit to doing so? A:  LocoNet should NOT be looped back on itself.  The design of LocoNet allows branching in different directions, but LocoNet must not be set up as a loop or ring topology.

Q: I would like to know about SE8C and signals on non-DCC layouts. A:  The SE8c is a signal driver for your layout. You can operate signals manually with any LocoNet Throttle and Command Station. Or, in your case, the SE8c can drive signals automatically with detection and compatible computer software such as RailRoad & Co. or JMRI.You will need detection devices to identify the presence of trains, a computer interface such as the PR3, a computer program supplying the signaling logic and the SE8c driving the signal heads themselves. Note that in a LocoNet environment, the SE8C supports detection: DS01 ...

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 ...
