SDCC1 BLOCK SIGNALLING DCC SHUTTLE & STATION STOP MODULE.
Runs a DCC equipped loco back and forth along a single section of track
Optional station stop function brings the train to rest at stations along the line
Can operate a train around a loop, stopping at stations along the way.
Easy adjustment of waiting times, just like a DC shuttle
Locomotive speed is set using an adjuster on the board
Quick and easy to connect and set-up
For a long while simple shuttles have been available to model rail enthusiasts to operate DC locos back and forth along a single section of track, simply setting the waiting time using an adjustment on the PCB.
For the DCC modeller, automatic control often requires expensive controllers or a willingness to control the model railway using computers.
Either of these can prove expensive, time consuming and complex, although for some this complexity is the very draw to this type of solution.
For the modeller looking for a quicker solution, we have designed the SDCC1.
This module is a self-contained DCC throttle, designed to operate a single loco along a section of track.
Upon reaching the end of the track, the loco will decelerate to a standstill, wait for a period, then accelerate in reverse.
It will then run to the other end of the track and decelerate to a standstill, wait again, and then accelerate off forwards.
This action would be appropriate to single line with one train and two terminus stations.
There is also the option to add intermediate stations. In this case, as the train enters the vicinity of the station, it automatically slows to a standstill, waits a set time at the station and then sets off again.
There can be any number of such stations on the single line.

UPDATE SEPT 21
The following information has been added to the user instructions and may allow your loco to operate with sound using the SDCC1.

Q. How do I control the loco headlight ?
A. There is an experimental menu item (29) in the SDCC1 that controls the headlight that uses a DCC Function Group One instruction.
Please review your decoder instructions in conjunction with this information.
Programming 29/2 turns the headlight on using FL(f) Function Group One group instruction 1 second before departing an end station.
The headlight is turned off when the loco stops at an end section.
Programming 29/1 turns off the headlight function completely (ie the SDCC1 will not issue any headlight instructions).
A factory reset (1/1) turns off the headlight function.
If you want to turn on other functions (such as sound, rear light, interior light, etc) at the same time as the headlight,
then check your decoder (and sound module if appropriate) instructions to see if CV33 in the decoder can be used to map FL(f),
to operate the required function(s) when the loco departs the end sections.
Note sound may draw more power than the SDCC1 can provide depending on the loco and may result in a shutdown.

Programming of the SCC1 is performed by pressing and holding down the Push Button when switching on the power.
The red led on the PCB flashes at 1 second intervals.
When the required number of flashes is seen (29) the button is released to store the first value.
At this point the led comes on for five seconds to confirm the value is stored.
The led then starts flashing again, and this time the button needs to be pressed to store the second value (2 for on, 1 for off).
Once the two values to be stored are entered, the led flashes 10 times rapidly, and the module starts operating.
