Hi guys.

Iv'e got a strange question for you guys.
Can any display (elevator information display and buttons) unit be used for any elevator.
I know certain types of setups only send certain signals (grey code etc.) but is there a way of connecting a modern Display unit to lets say a goods-hoist?.

What factors need to be considered when it comes to this. (Grey code, IO's etc).

Interested in hearing your opinions guys.
