Automatic addressing

Automatic addressing can be performed by a PC with ZAset software. The connections "ID1" and
"ID2" for "addressing" are connected with each other additionally next to the bus connection for this.
This means that it is no longer necessary to address every single member manually in the network.
On the first client that is connected directly to the terminal or the PC, "GND" and "ID1" or "ID2" must be
bridged. This is recognised as a result and occupied by address 1.
For the following clients the connection "ID1" or "ID2" of a client respectively is connected with
connection "ID1" or "ID2" of the next client.
The automatic addressing of other clients is initiated by the previous client via this connection.
Example for automatic addressing via USB converter

Connection of the clients via the terminals: A (D+), B (D-), GND and ID1 / ID2
