Application Diagram Up to 0 switchers can be daisy chained together with each switcher input separately fed and controlled by an optional accessory interface, the. Figure is an example of how several such switcher-interface combinations can be daisy chained together in a boardroom environment. By default, all switchers are set to input as the active input. Therefore, in a daisy chain of switchers the VGA and audio signals flow from one switcher to input of the next switcher in the chain. The switchers are daisy chained in this fashion until the last switcher in the daisy chain outputs to a projector and audio amplifier. Up to ten switchers can be daisy chained together without any degradation in picture quality. One power supply powers up to five switchers.

EXTRON 0-88-nn x ER:- yyyyyyyy yyyy User Guide (Continued) Autoswitching NOTES: Autoswitch mode must be disabled when daisy chaining switchers. If the autoswitch mode is enabled, the switchers cannot be daisy chained. RGsB and RsGsBs inputs and outputs occur in manual mode only. Autoswitching requires TTL level sync on pin 3 of the 5-pin HD connector. Pins,, and Ground when jumpered and shorted together (as shown at right) turn the autoswitching mode on. When the autoswitching mode is on, the switcher automatically switches to the input that has an active sync signal. If both inputs have an active sync signal present, input is selected, and the input LED indicator lights. If no active sync signal is present, the input LED indicator still lights to indicate that the unit is still powered on. CONTACT AUTO-SW NOTE: When autoswitch mode is active, both daisy chaining and the front panel input toggle switch are disabled, and the input cannot be manually switched. Any attempt to toggle the switch while the switcher is in this mode results in the flashing of the currently active input LED indicator. Contact closure is also disabled while in autoswitch mode. Setting the Jumpers NOTE: If you plan to use the and create a daisy chain configuration, you must configure the switchers before installing them in a rack or furniture and making connections. Daisy chaining switchers requires you to check, set or both internal jumpers in the switcher.. If applicable, disconnect all power to the switcher and any attached devices..
