Principles of Operation
This section describes the VS-411XS powerful operation principles:
• Input Auto-Switching on page 10.
• IP-Driven CEC Signals Routing via Built-in Control Gateway on page 11.
• Maestro Built-in Control and Automation Configuration on page 12.
• Maestro Kramer Aware Touch Panel Control on page 14.
Input Auto-Switching
Input selection is set by the DIP-switches (see Setting DIP-Switches on page 15) to either of
the following modes:
• Manual
• Auto – Last connected
• Auto – Priority
By-default switching is set to Auto Last connected.
When in manual mode, a manual switch to an unconnected input stays connected to output.
Manual switching overrides auto-switch mode.
In manual mode, select an input by:
• Pressing input front panel buttons.
• Using remote input selection switches (see Using Contact Closure Remote Control Pins
on page 16).
• Sending RS-232 serial commands control (see Protocol 3000 Commands on page 70).
• Using the embedded web pages (see Selecting an Input on page 23).
• Using Maestro Control on Kramer Aware touch panel (see Operating via Maestro
Kramer Aware Touch Panel on page 45).
In auto-switching mode, switching selection is performed based on either last connected or
priority input:
• In last connected mode, if the signal on the current input is lost, VS-411XS automatically
selects the last connected input, (the delay depends on a configurable timeout).
• In priority mode, when the input sync signal is lost for any reason, the input with a live
signal and next in priority is selected automatically, (the delay depending on the
configurable signal-lost timeout, (see Setting Auto Switching Priorities on page 34).
