d120 with 5.3

[TimJBennett]

Hi

You just repaired and returned to me my D120. You upgraded it to 5.3.
However my AP74 and D100 have not been upgraded yet. Can I reconnect the D120 and then start the upgrade program through my D100 without it causing a problem?

I upgrade my D10A with AP74 and the EMS-D10 one at a time with all  connected so I don't see why you cant do the same.  Actually I think you cant do it any other way at least for the D100 and D120 since they use separate connectors for uploading new firmware.  The AP74 gets updated in sequence when you update the D100.

Basically, turn on the D100 and AP74, but turn off the D120, then update the D100. That will update the D100 and the AP74 connected to it.
