If you have never used a Switch-It-MK2 before:
We recommend trying the decoder out first before installing it on the layout.
Connect a Tortoise
TM
machine to screw terminals 1A/1B of the decoder
Connect two wires from the decoder track connection to your DCC system.
When you first apply power to the Switch-It-MK2 the address display will show some
numbers (the software version) then 3 horizontal bars for about 1 second followed by
vertical bars”wig wagging” back and forth on the display. The wig-wagging indicates
the decoder is receiving DCC information and is ready for use.
Press the “SELECT OUTPUT” button the decoder until the output LED above the
1A/1B terminal strip lights (each push of the button will select a different output - on the
ninth push all LEDs will turn off). The address display will now start indicating the
output currently programmed for that output. For a factory fresh Switch-It-MK2 output
#1 it will flash 1. If you select output 2 it will flash 2 and so on as indicated below:
Factory default values for decoder
Output 1 factory programmed to accessory address 1
Output 2 factory programmed to accessory address 2
Now let’s actually test the decoder output #1.
Use your DCC system to throw the switch. The instructions below can be used for
throwing a switch depending on which DCC system you have:
To throw a switch using the NCE system:
Press “SEL ACCY”
Type in the desired accessory number followed by “ENTER”
Push “1” (or “2”) to throw the switch.
To throw a switch using a Digitrax system:
Press “SWCH”
Type in the desired accessory number
Push “OPTN” to throw the switch.
To throw a switch using a Lenz system:
Press “F”
Press “5”
Type in the desired accessory number followed by “ENTER”
Push “+” (or “-”)
If throwing the switch one way doesn’t do anything, try the other direction. You should
be rewarded with the Tortoise reversing its position
