There are two jumpers on the DS52 stationary decoder board. To properly use your DS52 you must be sure these jumpers are in the correct position.
The configuration jumper sets whether your DS52 operates slow motion or solenoid type turnout machines.
When the jumper is open it will run solenoid turnout machines.
When it is closed it will operate slow motion turnout machines.
The programming jumper determines whether the DS52 is in programming mode or not.
To program the addresses for the DS52 the program jumper must be closed. For normal operation, it must be open.
