6. Define Couplers

Each Input pin that has been wired to a coupler must be defined. The system scans all of the possible coupler input pins from Stops1 and Stops2 Input card address assignments, as described in the wiring outline. If turned on, the definition choice selected on the LCD will be written into memory or defined for this input pin. Every other pin that is not used for couplers must remain undefined.

Enter the Power Up Programming Sequence as instructed in Power Up Programming Overview. ‘Increment‘ with key 3 to 6. Define Couplers and ‘enter’ with key 8. The LCD will display “Write to Memory” and “D1/D1” “GT/GT 16”.

Use key 3 to increment the coupler definition, and key 2 to decrement this definition. Turn on the appropriate coupler to program this selected definition into the input pin’s memory. The LCD will go blank and increment to the next definition when the coupler is turned off.Use key 3 to skip any definitions that are not needed. Toggle key 8 to change the LCD from “Write to Memory” to “Read from Memory”. This allows the definition in memory to be displayed on the LCD when a coupler is turned on, thus checking that the definition in memory matches the engraving.

Use great key 1 to escape or exit. The LCD will auto increment to 7. Stop Programming.

NOTE: Check all stops, pistons, MIDI stops, and swell roller pins that are wired to Stops1 and Stops2 input card address assignments, they must say undefined.

NOTE: If no coupler choice is displayed when entering 6. Define Couplers, this indicates that a possible coupler input pin is on, thus blocking inadvertent programming of the pin.

NOTE: Key 6 will clear or erase or “undefine” all possible coupler input pins.
