Appendix I: Cascading
Appendix I. Cascading
Cascading multiple ServSwitch 4site Flex units—more than 4 video sources on a single display:
ServSwitch 4site Flex can be cascaded to display more than 4 video sources simultaneously on a single display.
In this master-slave-system, any ServSwitch 4site Flex can be used as master or slave. It is the same hardware. One ServSwitch
4site Flex is used as master unit. The console that has a keyboard, mouse, and display or touchscreen is connected to the output
of the master unit. A slave ServSwitch 4site Flex can be connected to each input of the master unit. In this way, each quadrant on
the display can be split in four more quadrants.
Example: In a setup with one master and four slave ServSwitch 4site Flex switches a total of 16 video sources can be displayed
simultaneously on a single console.
All display modes:
Display modes (Full-Screen, Quad, PiP, Win) of slaves and master can individually be set, combined, and switched, for example, the
master unit could be set to Quad mode, while the first slave is set to PiP, the second slave to Full-Screen, the third slave to Quad,
and the fourth slave to Win mode. Any combination is possible.
Keyboard and mouse operation:
You can activate the keyboard and mouse on any of the up to 16 computers connected.
Hotkeys for switching:
Use hotkeys to quickly activate any of the (for example) 16 channels or to switch the display mode of any of the ServSwitch 4site
Flex units in the master-slave-system.
Different levels (master or slave) require different types of hotkeys.
For example, keep the hotkey default setting <Hotkey1> = <Ctrl> + <Alt> for all slave ServSwitch 4site Flex units.
Just change the hotkey setting for the master ServSwitch 4site Flex to (for example) <Hotkey2> = <Ctrl> + <Win>
Example: In a cascaded ServSwitch 4site Flex setup with one master, 4 slaves, and 16 computers connected, you can activate
keyboard and mouse of computer 16 by pressing the following hotkey combination:
<Hotkey2> + 4 (to activate Channel 4 on the master level), then <Hotkey1> + 4 (to activate Channel 4 on the slave ServSwitch
4site Flex connected to Port 4 of the master)
Example: To change a display mode of (for example) the slave ServSwitch 4site Flex connected to Port 4 of the master ServSwitch
4site Flex, press the following hotkey combination:
<Hotkey2> + 4 (to activate Channel 4 on the master level), then <Hotkey1> + P to switch from default Quad mode to PiP mode
in this quadrant. The result is a screen split in four equal quadrants. All quadrants are split again in four equal quadrants (Quad
mode), just the quadrant in the lower right corner (Channel 4) is showing its four sources in PiP mode.
NOTE: Use a programmable keyboard for comfortable switching of cascaded ServSwitch 4site Flex. Behind a single key, you can
program a combination of hotkeys. By pressing a single key you can activate keyboard and mouse of one of (for example)
16 computers connected or the switch display mode of the master or any of the four slave ServSwitch 4site Flex.
