Optionally the device can be switched via a Perl script or external tools like wget. More information is available on our support wiki at www.gude.info/wiki. The website contains a status overview of all passive signal inputs, the time since the last change, and a counter of switching changes.
Page 17 For devices with relays, entering or exiting the bootloader mode does not change the state of the relays as long as the operating voltage is maintained. The GBL_Conf.exe program is available free of charge on our website www.gude.info and can also be found on the enclosed CD-ROM.
