NCE Switch Kat decoders: Instructions say to connect 2 wires to track power and 2 wires to turnout. If the wires from the track rails and the wires from the two Switch Kat track posts are reversed, will that cause a short? Which turnoutout wire connect to which Switch Kat post to determine turnout direction? Switch-Kat decoders have wire connection for signal lights: "N" and "R" Two NJI 2103 color signal's lights: red and green. Which wire from the NJI 2103 connect to the "N" and which to the "R" post. Can the light wires be changed/corrected after programing or would you have to reprogram then? Thanks.
Connecting the track connections in reverse will cause no problems, as the connections are not polarity sensitive. Connecting the switch outputs to the rails, however, may damage the switch-kat. The switch connections may be reversed with the only effect being the reversal of the turnout action. Same holds true for the indictor lights. the "N" connection would normally connect to the green and the "R" to the red, but if the indication is reversed from what you want you can reverse the connections.
Follow up question Is this correct: Connect the turnout wires to the Switch Kat either way but not to the rails. After programing the Switch Kat if the turnout direction and signal lights are not the way I want them, I can switch the wires and reprogram the Switch Kat. First time DCC, and want to be sure. Thanks.
You can switch wires or re-program. Your choice. It's as described in the instructions. Note that the switch-kat is designed for Kato and LGB (2-wire) switch machines only. Not for 3 wire solenoids or stall motors.
