The parameters of the change-over functions can be set by the Ghielmetti Software. You have to download the onto your local PC which is connectet to your TCP/IP LAN. The Change-Over has to be connected to the same LAN by the RJ45 port. Follow the installer after download from the Ghielmetti Web Site. Select the device: Select the button Connect to connect the C/O to your computer. The Soft Control Panel will be opened. The change-over switches automatically if the level of an input signal goes higher or lower as the fixed value. The relation of input level and response time may be set individually for minimum and maximum input levels. -78 dbfs -24 dbfs -75 dbfs -21 dbfs -72 dbfs -18 dbfs -69 dbfs -15 dbfs -66 dbfs -12 dbfs -63 dbfs - 9 dbfs -60 dbfs - 6 dbfs -57 dbfs - 3 dbfs -54 dbfs 0 dbfs -51 dbfs -48 dbfs 0.2 s 0.025 s to 0.050 s 90.0 sec max. 0.1 s 0.2 s 0.5 s

The Change-over may be controlled by Software over TCP/IP. The same features as with the control panel are available. You have to download the onto your local PC which is connectet to your TCP/IP LAN. The Change-Over has to be connected to the same LAN by the RJ45 port.
