I am programming up a load of eDLT's at the moment and I am find some of the eDLT can take 2-3 minutes for a save to the unit (no save to database). Painfully slow. I like to program up the keypads send to the keypads, check for any programming errors and once all is OK then send to the database. So I might a PITA. Some of the unit rip along OK so it not all. I have the laptop connected via a 8 port unmanaged switch which in turn is connected to a CNI. Hard to ascertain if it is a LAN network issue, a C-Bus network issue a eDLT. Anyone else experienced very slow uploads to a eDLT keypad? I am using 1.13.2 TK. Regards, Fleetz
