In the master matrix the videoloss indication may be one of three types:
1) Videoloss on a local channel of the master matrix
The normal message “
Videoloss camera
Cam ” is shown, without the flashing

on the right.
The abnormal status is shown in the event log of the master matrix.
2) Videoloss on a channel of the slave matrix recalled by the master
The normal message “ Videoloss camera Cam ” is shown, with the flashing <S> on the right.
The abnormal status is shown in the event log of the slave matrix.
3) Break in connection between master and slave matrixes
The message “ VLoss slave NumSlave / CamSlave -> Cam CamMaster <S> ” is shown
NumSlave is the number of the slave matrix and CamSlave the number of the video OUT that has lost
the connection; CamMaster is the number of the master matrix video IN is not receiving the video signal

7.6.4 Example of composite master/slave installation
In this example the installation has three matrixes: two slaves (SLAVE1 and SLAVE2) and a master
responsible for supervision (MASTER). Control is entrusted to three operators: two operators control only
the local cameras (KS1 and KS2), the master operator can request any camera.
KS1 is only allowed to select the cameras connected to the SLAVE1 matrix, KS2 is only allowed to select
the cameras connected to the SLAVE2 matrix. Kmaster is able to control the cameras directly connected
to MASTER and also to select max. 4 cameras from SLAVE1 and max. 4 cameras from SLAVE2.
