  1. questionBD4 - Connecting to an SE8C
    Connecting BD4 to an SE8C? The BD4 is a block occupancy detection device designed as an add-on device that can take advantage of the LocoNet hosting capability of the SE8c signal decoder. It is connected this way: The installation of a BD4 is relatively simple. Looking at the BD4, you will f ...

  2. questionBDL168 use with SE8C?
    Q:

  3. questionSE8C - Installing Position Light Style Signals For Pennsylvania RR, B&O and N&W Signaling
    The SE8C can drive position light type signals such as those used by the Pennsylvania Railroad and the B&O RR and the N&W RR. Leads from the signals can be soldered directly to the pads on the Signal Mast Base (the Terminal Strip Mounting Kit can also be used for interfacing your sig ...

  4. questionPowering 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& ...

  5. questionSE8C - 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 ...

  6. questionHow 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 ...

  7. questionSE8C - 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 "Appro ...

  8. questionSE8C - Initial Setup & Testing
    We recommend testing your new SE8C prior to installation on your layout. The following testing procedures will help familiarize you with the general operation of the SE8C. No track power is required for testing, but you will need a working LocoNet connection and throttle or PC running DCC con ...

  9. questionSE8C - Resetting SE8C
    If you want to reset the SE8C to its factory settings, follow this procedure: No track power is required for testing, but you will need a working LocoNet connection and throttle, or a PC running DCC control software that is connected to LocoNet. a. Press and hold the Option Button until the r ...

  10. questionSE8C - Detection Inputs
    Detection Section Inputs DS01 to DS08 (see below) are inputs from occupancy detectors that provide at least +5V (max 22V) when occupied, and 0V when unoccupied. The SE8C sends occupancy messages to LocoNet when these inputs change. If these detection section inputs are not disconnected, they w ...

  11. questionTSMK - Terminal Strip Mounting Kit
    The TSMK, Terminal Strip Mounting Kit, includes 2 terminal strip boards with resistors for easy installation. The Digitrax Terminal Strip Mounting Kit makes it simple to connect any scale or model signal to the Digitrax signaling system without soldering. Simply connect the wires from the sign ...

  12. questionSE8C - 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 lo ...

  13. questionSE8C 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 ...

  14. questionIntroduction to the Digitrax SE8C Signaling
    Security Elements The 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 securit ...

  15. questionSE8C 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 ...

  16. questionSE8C 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 easie ...

  17. questionSE8C - Can you operate more than one slow motion turnout from one output?
    Q: Can the SE8C slow motion turnout controllers operate multiple turnouts from one output? A: No. The slow motion connection was originally intended to be used with single slow motion drives for semaphores, part of the overall design of the SE8C signal driver. Since only one semaphore is oper ...

  18. questionSE8C Output to LEDs
    Q: I am hoping to buy O gauge signals from Custom Signals to operate on my Digitrax layout. To be sure that they will work properly, they would like to know the output voltage to the LED's and the inline resistor value. A: The typical output of the SE8C ranges between 4.5 and 5.0 volts DC; it ...

  19. questionSE8C - Signals On Non-DCC Layouts
    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 so ...
