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!

Don't remember any jumper changes. Definitely go J2 before J3 as the CPU assigned numbers
Logically in order although you could do a DN renumber

I believe that the APM4 is the analog station module. If it is I have only seen one instance where there was more than 1. It had a special cable to attach to the digital station ports.

Daniel,

I've never seen the special cable. Did it come with spare APM4 cards, or did it have to be purchased separately? Any idea whether it's just absent of outer wires, or manipulated in some other way?

Thanks!

I only saw one and it was already installed. So I am not sure if it was just missing pins, or what.
