Is there anything I would need to consider, if adding a second APM4 to a DX80? I guess I can add it to either J2 or J3. Is the ribbon cable different? If I remember correctly, a cold start is required when adding/removing cards. I'm just wondering if there's anything else to consider. I can't remember if there is a jumper to move if using an APM4 instead of a DPM8.

Thanks!
