  • Page 3: Introduction

    Adjustable brightness level • Ability to change the network time and fast rate • Two LocoNet jacks for connecting to other LNFCs or other LocoNet products • Pre-mounted fascia plate ready for easy installation; can be installed in a standard Radio Shack project box...

  • Page 4: Theory Of Operation

    This is illustrated below. The LNFC will then enter the current time mode or idle mode depending upon whether or not the LocoNet is active. Each LNFC keeps its own time internally but relies upon periodic LocoNet fast clock messages for synchronization and new time or fast rate settings.

  • Page 5: Event Trigger Feature

    LNFC supports this capability when used in conjunction with DCC Accessory Decoders (e.g. Digitrax’ DS54, CVP’s AD4, etc). The LNFC sends accessory decoder commands via LocoNet. The Digitrax command station then translates these commands into the appropriate DCC packets. As such it is absolutely NOT necessary for the accessory decoder to be LocoNet-capable.

  • Page 6: Display Modes

    Quick Start Guide The LNFC is ready for installation. You should be able to have it up and running on the LocoNet in a matter of seconds (real time seconds, not fast time seconds!). Follow these simple steps: 1. Plug either end of the enclosed LocoNet cable into either jack on the back of the LNFC.

  • Page 7: Choosing A Fast Rate

    6. If there is already another LNFC connected to the LocoNet then stop clock here and refer to Section 6.1 on establishing the LocoNet master. If this is the first/only LNFC then proceed to the next step. 7. The LNFC and any fast clock-aware devices (e.g. DT100 throttles) will be synchronized and will display the current time.

  • Page 8: Edit Mode

    Edit Mode The edit mode uses the LNFC’s four front panel keys as well as the display. The key functions are summarized as follows: MODE: Press this key to enter the edit mode. Press it again at any time to return to the current time mode.

  • Page 9: Current Time ("Cloc")

    Current Time (“cLoc”) INIT TIME ALARM The current time can be changed by pressing the SEL key when the display shows “cLoc”. The current time will be shown and the time indicator will be illuminated. The PM indicator will only be illuminated if you’ve chosen the 12 hour time format and the current time is PM! For example, if the current time is 20:35 (24 hour format) the display will look like this:...

  • Page 10: Fast Rate ("Rate")

    Fast Rate (“rAtE”) INIT TIME ALARM The fast rate can be changed by pressing the SEL key when the display shows “rAtE”. The current fast rate will be shown. For example, if the current fast rate is 8:1 the display will show: INIT TIME ALARM...

  • Page 11: Alarm Time ("Alar")

    Alarm Time (“ALAr”) INIT TIME ALARM The alarm time can be changed by pressing the SEL key when the display shows “ALAr”. The existing alarm time will be shown and the alarm indicator will be illuminated. The PM indicator will only be illuminated if you’ve chosen the 12 hour time format and the current time is PM! For example, if the existing alarm time is 10:30pm (12 hour format) the display will look like this:...
  • Page 12 Notice that the alarm indicator is illuminated and the leftmost decimal point indicator is also lit. This indicates that the display is showing the switch address (in this case switch address 8) associated with the Alarm Event Trigger. In this example the PM indicator is also illuminated; this indicates that when the event trigger is sent it will set the switch to closed.
  • Page 13 Event Trigger (“Etr”) Pressing the SEL key when the display shows “Etr” will allow you to enable or disable the Event Triggers for this LNFC. After selecting which events are enabled/disabled you can set each event’s (with the exception of the alarm event;...
  • Page 14 “weights” for each of the events that you want to enable. For example, if you want to enable the Alarm Event, Event #2, and Event #3 then you would add the following values: = 13 (Alarm Event + Event #2 + Event #3) For any events that you want to disable simply don’t add in their bit weights.
  • Page 15 Change the hours by pressing the +/HRS key; the hours will increment from the current setting up to 23 (or 11pm) and then “wrap-around” to 00 (or 12am). Change the minutes by pressing the -/MIN key; the minutes will increment from the current setting up to 59 and then “wrap-around” to 00.
  • Page 16 “duration” type. If you change your mind and don’t wish to change the event end time, simply press the MODE key; the display will return to the current time (adjusted for any fast time minutes elapsed while in this editing mode). Once you are satisfied with the event end time press the SEL key;...
  • Page 17 (adjusted for any fast time minutes elapsed while in this editing mode). Once you are satisfied with the switch address and switch state press the SEL key; the switch address will be in effect and stored in non-volatile memory as well. The display will then show “Et#S” again where “#” is the next event number.

  • Page 18: Brightness ("Brit")

    Brightness (“brit”) INIT TIME ALARM The display brightness can be changed by pressing the SEL key when the display shows “brit”. The current brightness setting will be shown. “br L” means low brightness; “br H” means high brightness; “br A” means automatic brightness (Low from 7:00pm to 6:30am, High from 6:31am to 6:59pm).

  • Page 19: Initial/Default Time ("Init")

    Initial/Default Time (“Init”) INIT TIME ALARM The initial (default upon power up) time can be changed by pressing the SEL key when the display shows “Init”. The existing initial time will be shown and the decimal point to the lower left of the units of hours digit will be illuminated.

  • Page 20: Code Revision ("Co X.y")

    Code Revision (“Co X.Y”) The current code revision is displayed. The example above would indicate that this LNFC-1 contains software code revision 4.0. Normally you don’t need to be concerned with this. However, if you require technical support we may ask you for this information. Pressing the MODE key will change the display to the current time (adjusted for any fast time minutes elapsed while in this editing mode).
  • Page 21 Usage Actions Weight 12 Hour Format 1: Time is displayed in a 12 hour format utilizing PM indicator. 0: Time is displayed in a 24 hour format; the PM indicator is not used. Clock Master 1: LNFC is disabled as the Clock Master. Disable 0: LNFC is enabled as the Clock Master.
  • Page 22 When you press SEL the display will look something like this: INIT TIME ALARM In this example the LNFC would display time in a 12 hour format and would flash the colon when the clock is running (fast rate > 0). To change a function value you must first determine what the new decimal value will be for the option switch.

  • Page 23: Reset ("Rst")

    So for our example the hexadecimal equivalent for 37 decimal is 25. Use the +/HRS and -/MIN keys to adjust the value on the display. Pressing the +/HRS key will increment the option switch value; the value will increment from the current setting up to 3F and then “wrap-around” to 00.

  • Page 24: Multiple Lnfcs

    Multiple LNFCs Establishing the Clock Master When using multiple LNFCs on the same LocoNet it is necessary to assign ONE the role of Clock Master and the OTHERS as Clock Slaves. The role of Clock Master simply means that one module is responsible for broadcasting the initial/default time when it is first powered up.

  • Page 25: Pausing The Clock

    (if you enabled it to flash). All fast clock-aware devices on the LocoNet will have their fast rates set to 0 but the Clock Master will retain the fast rate used prior to entering the pause mode. The clock is also paused when the Clock Master is first powered on if the Power-on Pause option is set to 1 (see section 5.7).

  • Page 26: Mounting The Lnfc

    The fascia plate was designed to allow you to mount the LNFC inside a Radio Shack project box (p/n 270-1805). Discard the covers that come with the project box. Be sure to drill holes in the box to allow the LocoNet cable(s) and power connector to pass through.

  • Page 27: Regulatory - Fcc Information

    The LNFC contains no end-user serviceable parts. If you believe your LNFC needs repair please contact Logic Rail Technologies prior to returning it. Logic Rail Technologies reserves the right to repair or replace a defective product. Products that have voided the warranty or are out of...
