Hi Mr Bachmann

I'm on the way to install a Zimo MX 690S DCC sounddecoder. In this decoder the DCC power and the sound is in one only item, and the decoder is detecting the power consumation of the motor to adjust the sound volume. I've connecting J1-5 Chuff Trigger 1 with the switch input 3 of the sounddecoder. This input is producing a chuff every time if the switch input is connecting to ground. so too I've connecting  the J1-7 ground with the decoder ground
But it doesn't work till now.
Does i need to connect the locomtive 1 and ground with the decoders 1 and ground?

Thank you for helping

To properly work the decoder must power the locomotive electronics.

Connect the Decoder + to the locomotive +.  Connect the decoder ground to the locomotive ground.

Connect the locomotive chuff trigger to the decoder trigger. 

Hope that helps.
