If it’s a standar piezo/piezo diy it should work on a TRS cable and DM10 inputs .
Fist check that DM10 is set to piezo and not switch mode .
If it’s already , you may have to resolder and swap the tip with the ring.
Before doing that , lower tha zone crosstalk to zero and retrigger to zero ,hit the rim to see if you get sound to confirm this.
Edit :
If the wiring was wrong you can easily check it since the head will produce rim sounds .
