5.14.2 Automatic addressingAutomatic 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 bebridged. 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 withconnection “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 converter11.11.2013v_modbus_autoadr_zaset.vsdID1 GND A(D+)B(D-) ID2MODBUS(RS-485)AddressingAddressingID1 GND A(D+)B(D-) ID2MODBUS(RS-485)AddressingAddressingA(D+)B(D-)GND (X)USBUSB-485-Mini/OPOn the USB-485 converter connection to the terminals: A (D+), B (D-) and GND.Connection of the clients via the terminals: A (D+), B (D-), GND and ID1 / ID2Information• Except the data link “A (D+)”, “B (D-)” the “ID1 - ID2” and the “GND” connection may no further cablecores of the data line be used.• The connections for the automatic addressing “ID1” and “ID2” are not directly connected with eachother internally. These may not be bridged; any order of connection is possible.• When using the automatic addressing, no repeaters can be used because these do not pass thesignal through to the addressing.5.15 USB-interfaceOver the USB interface if necessary a software update can be made. For this a consultation with ourV-STE support department for control systems-ventilation technology is necessary.For communication with a PC (Virtual COMM Port) we make the necessary programs available onrequest.Danger due to electric currentPlug the jumper J1 to both PINs only for a software update via USB interface. The device will notswitch on if this jumper is plugged to both PINs!Do not replug the jumper under voltage, observe the safety instructions!Operating Instructions Fcontrol – model series FKDM25/32AM-C Electrical installationL-BAL-E214-GB 1446 Index 002 Part.-No.18/99
