1. SE8C Factoids
09 September 2014

2. Topics Connection Diagram Introduction Topology of LAMRS SE8C Use
SE8C Locations
Our units are mounted connector down (so this view is upside-down)
Each board has a unique id and this is indicated on the 44-pin connector

3. Please refer to the SE8C Manual
This is the connection diagram.
Typically, our connectors are wired to European Connectors, labelled with the corresponding terminal letter or number
Power is wired to terminals “C” and “3”
When powered
Green LED is on
Red LED blinks when any command is sent (for-example an engine speed change)

4. SE8C Introduction SE8Cs are used to control turnouts and signals
Each board can control up to eight turnouts and 32 signals
Normally, each turnout has four signals
Turnout control and signal control are independent functions
Signals at a turnout may be powered by different boards from the turnouts themselves

5. Control of Turnouts
SE8Cs need not be connected to the Loconet to control via pushbuttons
Push buttons are wired directly to a powered board
These actuate the Tortoise machines that are also connected to the boards
Control via throttle or computer requires that each board have a unique address and be connected by Loconet to the Command Station (usually through a daisy chain)
LAMRS Boards 1-7 and are used for turnout control
…and in some cases for signal control as well

6. Control of Signals
Signal algorithms are hosted by the computer (RailRoad & Company)
SE8Cs used for signals must have a unique address and be connected by Loconet to the Command Station
Signals are wired via flat cable to each of the eight Driver (Drv) connections
We have some SE8Cs that are only used for signals
Boards 8 (Harbor West) and 9 (Itasca)

7. Our Turnout Control We use nine boards for turnout control
whose ids are in sequence, 1 through 7, for the mainline
whose ids are in sequence, 10 and 11, for Ford Yard West and East
Board failures will map to the table
