Hi tainspotterr,
when the complete Lenz-Software including the usb-to-serial-driver is installed, the computer must have a special com-port , i.e. "Com 3" that is used by Windigipet to access the interface. You can find the Com-Port using the Windigipet-Application "interface finder" oder something like that.
When Using the interface by Windigipet, alle Lenz-Applications using the interface must be closed, also the "Li-Server".
This Com-Port (i.e. "Com 3") must be selected in the "system-settings" of Windigipet while the Option "Lenz over ip" must be deactivated and Baudrate is 57600.
best regards
Frank
