Factory reset:
To reset the Switch-It-MK2 to original factory setting program CV8 to 8. A reset will
only be performed if you program CV8=8 via Accessory OPs mode programming to the
address of output 1.
Upon reset all settings will revert to the factory default setting as indicated below.
Factory default values for decoder
The Switch-It-MK2 is factory programmed to the following values
Output 1 = accessory address 1
Output 2 = accessory address 2
CV548 is set to 0 (normal dual pushbutton operation by the optional Button Board)
CV556 is set to 0 (pushbutton lockout not engaged)
CV561 is set to 0 (normal output polarity)
CV562 is set to 0 (normal output polarity)
Other technical stuff:
v
We have successfully controlled two Tortoise switch machines with one decoder
output when used in a crossover. We can't guarantee this will work in all cases.
v
The outputs of the decoder are always on to prevent the switch machine from backing
off due to the spring pressure of the turnout throw mechanism.

More wiring tips:
If you use the Tortoise contacts to power the frog of your turnouts we suggest
wiring a #93 (other useful bulbs #211, #305) automotive bulb in series with the frog
(see below). This will prevent short circuits from shutting down your power booster
in the event you enter the turnout from the frog end without aligning the points. For
larger scales use a #1156 bulb.
See the diagram below for and easy way to have turnout position indicator lights.
LEDs are wired in series with the switch machine to indicate which position the
turnout is thrown. Most LEDs will handle up to 20mA, the switch motor acts as the
current limiting device for the LEDs. We use red and green LEDs but any color will
do. The switch machine will run a bit slower with LEDs installed due to about a 1.5
volt loss in the LEDs
.
