KB132 SE8C - Yellow Signal Indication with Bi-Polar LED

I would like to use a Tomar Searchlight Signal such as model # 858. It has three color LED for each head. The SE8C manual shows the wiring example for bi-color LED signals. Is the SE8C able to control the three color LED signals as well? The bi-pole LED's can be used to produce a yellow "Approach" indication. The SE8C sends an AC signal to the LED, alternately lighting both the red and green sides to make a yellow (or "amber") Indication. Please see below: "A2" is connected to produce an approach (yellow) indication. You may find that the yellow ...

KB133 How do I mount the 44 pin edge connector boards?

My question is: How do I mount the PM42? Do I need a special housing in order to mount it under table? It appears to me that mounting it flush against a surface would prevent, or make it extremely difficult, to attach the 44-pin connector. Digitrax manufactures three devices which have a 44-pin connector. These are the BDL168 (and its predecessor the BDL16), the SE8C and the PM42 (and its predecessor, the PM4). These best approach to mounting these devices is to screw the connector directly to the wiring panel board. Drill mounting holes in the end of the 44-pin ...

KB905 BDL162 - Increase Detection Section Threshold Sensitivity

How do I Increase BDL162 Detection Section Threshold SensitivityThe BDL162 has Option Switch settings to control detection sensitivity. The factory setting is OpSw19=t for a threshold sense for DCC occupancy of approximately 22 Kohms minimum. Changing OpSw19=c will set the threshold to 10 Kohm minimum. See the BDL162 instruction manual for details on setting the Option Switches. These settings will accommodate most layouts, though there may be circumstances when a higher threshold is desired, for example, in a high moisture environment or with G scale operations outside.To raise the threshold even further resistors can be added into the wiring between ...

KB407 SE8C Signal Controller Address Ranges for Signals and Other LocoNet Devices

The SE8C uses switch addresses to operate the signals, so you may need to change some factory settings to make it work in conjunction with turnouts that are already installed on your layout. Be sure that when you configure the SE8C that the switch address ranges you select to operate the signals do not conflict with other devices, like DS64s, that are already installed. We strongly recommend that you keep accurate documentation of the address ranges used to control all devices on the layout to avoid conflicts that might cause problems. Without this record it can be very difficult to ...

KB268 Powering the SE8C

What are the power requirements of a SE8C? Any power supply that can provide 12-15 volts either AC or DC with a minimum current rating of 100 ma is all that is necessary to power a single SE8c. Digitrax recommends the PS14 for powering the SE8c. A single PS14 has the ability to power two SE8c’s. When connecting multiple SE8c’s to a single power source the total maximum current requirement of the power source is computed by multiplying the number of SE8c modules by 100 ma (Example: 3 SE8c’s would require a 300 ma power supply - 3x100=300). The edge ...

KB142 SE8C - Voltage Output

My signals are supplied with current limiting resistors and require 12v max to operate. What are the voltage outputs from the SE8C and does this differ depending on the supply (15V AC or 12V DC). The output voltage is 5 volts, regardless of the input power. It is powerful enough to drive LED's, but it cannot handle incandescent lamps.

KB406 SE8C Signal Controller Cable Pin Out

The individual signal heads are connected to the SE8C with 10 conductor ribbon cables. Depending upon which way you assemble the ribbon cables, Pin 1 can be either the brown colored conductor (called Phase A) or the black colored conductor (called Phase B). To maintain your sanity it seems easiest to be consistent when choosing either conductor, but there is no "wrong" answer. In the example below, the ribbon cable is being set up using the brown cable as Pin 1, thus it is being configured as "Phase A" The table below shows the various connections which result when setting up ...

KB409 SE8C Board Layout

Individual signal heads are driven from connections marked DRV1 - DRV8. Although these are typically connections to individual signals, they can serve more than one signal as necessary. The ID Button is used to set the individual SE8C board ID. If using more than one such circuit board, each must be assigned a unique number so that the system recognizes it. The Option Button is used to customize the SE8C. LocoNet Jacks provide a data channel for the SE8C.

KB408 Introduction to the Digitrax SE8C Signaling

Security ElementsThe Digitrax Signaling System is organized around the concept of what we call "security elements", which are similar to what U.S. prototype railroads call "plants" or "interlockings". The Digitrax SE8C signal decoder displays aspects for up to 32 heads for 8 individual security elements (plants) using either a LocoNet Throttle or a computer with compatible software. When used with associated occupancy detectors and compatible software, the SE8C can be set up to protect the turnout with signals as shown by the example below. Note that trains can move from A to B, A to C, B to A or ...

KB411 AR1 with BD4 for Block Detection

How do you wire an AR1 with a BD4 so that you get block detection within the reverse loop and without the BD4 permanently detecting the AR1? It should be wired with the AR1 between the power source and the BD4. All four detection sections of the BD4 will have to be inside the reverse loop.

KB48 BDL168 - Option Switch Table

The option switches and settings you can use to customize your BDL168 are indicated in the table below. These option switches on your BDL168 are set up using a Digitrax throttle's SWITCH commands. (This can only be done with a Digitrax LocoNet throttle or equivalent software). SWITCH mode is normally used for operating turnouts by issuing closed ("c") or thrown ("t") commands. In the case of your BDL168, each switch address is a BDL168 option switch. The following table shows what each OpSw is used for when it is set for thrown or closed. Factory settings are indicated by shaded ...

KB390 DS64 - Sensor Activated Exit Routes

In this example we add some more features to complete the capabilities of the DS64 / BD4 combination. In addition to the fascia button, we utilize the remaining sensors of the BD4 to automatically select the exit route if triggered by the advancing train. For this purpose, each yard track will need a short detection section just before the yard ladder. A departing train will then trigger and set its own exit route as soon as the engine enters the detection section. To enter the yard however, the routes must still be selected manually with the push buttons.

KB391 DS64 - Sensor Activated RR Crossing Lights with the addition of a BD4

You can automate grade crossing signal lights with block occupancy sensors. Install a BD4 to detect track occupancy as shown in the figure below. Other than removing the Op Sw35 commands from the routes used in the related article example, there is no additional programming needed for the DS64. Sensor operated occupancy detection requires that all rolling stock be equipped with resistor wheels for proper detection or that the detection section is longer on each side of the RR Crossing than the full length of a train since only the locomotive will draw current. A lighted caboose on the end of ...

KB47 BDL168 - How to Change the Option Switches

KB50 BDL168 - Using with Power Managers

The BDL168 is designed to be used with power management devices such as PM42. The BDL168 is designed to operate “downstream” of the Digitrax boosters and power management devices. The BDL168 is the "last" device in the chain from booster to power manager to BDL168. It is connected directly to the track detection section. There should be no other connections to any detection section that will draw track power or the detection section will always show occupied. If a device is used to switch off power feeding the BDL168 and the track it is connected to, for example, a PM42 ...

KB51 BDL168 - Using In a Reversing Loop

The BDL168 can be used as an autoreversing unit for return loops. One of the BDL168 Detection Sections is connected to the non-reversing area, with the balance of the detection connections being made within the reversing area. Here is a wiring example: Note that an auto-reverse section can only use detection sections that are contained in a BDL168 zone that is correctly set up for auto-reversing.

KB53 BDL168 - Outdoor Layouts

Reducing Sensitivity for Outdoor Layouts Outdoor layouts may require reducing sensitivity to allow for more accurate occupancy reporting through the BDL168. Resistors are connected between the detection zone and the zone common from the blue connector to reduce sensitivity. A 1KOhm resistor will reduce the sensitivity by 1/2. A 100 Ohm resistor will reduce sensitivity by a factor of 10.

KB54 BDL168 - Troubleshooting Checklist

Here are several things to check if you are having trouble with the BDL168: Packet Reception Be sure the green ID LED is ON & is “winking” off about every 2 seconds. This means that correctly formatted DCC packets are being decoded from the left most (Railsync) pin of the RJ12 LocoNet socket. For DCC detection, the same DCC packet signal that drives the booster must be connected to the RJ12 socket's left most pin. If you are using LocoNet and you do not see the green LED blinking pattern described, check to be sure that the system is powered ...

KB55 RR&Co Settings for BDL168 Operation

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.

KB56 BDL168 - 44-Pin Connector Pinout Configuration

BDL168 Pin Out Configuration: Notes: 1) All connector pins are paired top (component side of the BDL168) and bottom (solder side of the BDL168) except 11/M and 12/N. For 6 Amp current rating with 3 Amp connector pins, track/zone wires must be connected to both pin pairs: e.g. Zone A = pins 1 & A (See Figure below): 2) Letters G, I, O & Q are not used as pin designations on the connector. 3) Power connections should be made to a power supply dedicated to BDL168 use only. Multiple BDL168 units can be supplied by a single shared supply ...

KB57 BDL168 - Connecting to a "Common Rail" Wired Layout

Common Rail Wiring Many older model railroads use Common Rail wiring because they were initially wired to operate with electrical toggle switches. Conversion to DCC is possible with Common Rail, but it is not recommended. Whole layout common rail is a method of wiring layouts where power districts and their boosters are electrically connected using a common rail or common power bus return wire. Whole layout common rail wiring is a disadvantage when it comes to detection systems since detectors cannot independently monitor whether zone power is on or off so they can't tell whether occupancy detection is working in ...

KB58 BDL168 - Connecting to a "Direct Home" Wired Layout

Direct Home Layout Wiring Digitrax strongly recommends direct home wiring where each power district and its booster are electrically isolated. This method of wiring has safety advantages and makes troubleshooting problems easier. In addition, direct home wiring makes detection work more prototypically. With direct home wiring, the BDL168 can determine and indicate whether any of its 4 zones is powered or not (possibly short-circuited) even when there is nothing on the rails in the detection sections. The BDL168 factory-set logic causes the detection sections to show "occupied" if the associated zone's power is off (because in this case, detection is ...

KB59 BDL168 - Terminology

Here are some terms that you might find useful as you work with the BDL168. Direct home wiring is a layout wiring method where each power district and its booster is electrically isolated. The track within each power district uses a "common return" wiring method for occupancy detection and/or power management. Direct home wiring is the wiring method recommended by Digitrax for safety reasons & also because it makes detection work more prototypically. Power district is the power wiring, track, components and equipment attached to that wiring, driven by a single properly isolated booster. The track for a power district ...

KB60 BDL168 - Connecting two RX4's

The BDL168 manual states that 2 RX4's can be connected but it only shows how to connect one of them on Aux 2. How is the second RX4 connected? The RX4 is a 4 Zone Transponding Receiver Add-on for BDL16 series occupancy detectors. Each RX4 is made up of 4 RX1 sensors, a ribbon cable and a connector that lets you plug the unit into a BDL16-series detector. The earlier BDL16 and BDL162 occupancy detectors had the capacity for hosting one RX4. BDL16 & BDL162 boards are labeled with AUX1 & AUX2. Only the AUX2 connection should be used for ...

KB61 BDL168 - Using two boosters

KB66 SE8C - Local Switch Inputs for Turnout Operation

SW01 to SW08 are inputs that allow a local switch mounted on the layout to operate the slow motion turnout machine. For example, SW01 when connected to the +VE sensor common (Pin 2 in figure) will reverse the voltages on SMTM1A and SMTM1B to change the position of turnout 1. SW02 controls local turnout 2 , etc. For each connection to +VE sensor common the slow motion turnout machine swaps direction and a Switch message is sent to LocoNet to report the new position of the turnout. This local control can be disconnected by setting OpSw 15 to closed, in ...

KB67 BDL168 - Setting Up Board ID

When the BDL168 is connected to LocoNet, it will communicate coded detection information to the system. If you wish to report BDL168 status to LocoNet and attached devices or computers that can interpret these messages, you will probably want to set up a unique board address for each BDL168. This is done so that the BDL168 Board ID does not conflict with the Board ID of other devices on the railroad. Board addresses can range from 01 to 999. It is recommended that you make a record of the addresses you use for all devices connected to your layout. Setting ...
