Introduction to Trigger Out
Trigger out, often referred to as a trigger output or simply trigger, is a feature found on many modern projectors. It allows the projector to send an electrical signal to another device, typically to turn it on or off, or to perform a specific action. This feature is particularly useful in home theaters, conference rooms, and other environments where automation and synchronization of devices are desired. The trigger out feature can significantly enhance the user experience by automating tasks that would otherwise require manual intervention.
How Trigger Out Works
The trigger out function works through a simple yet effective mechanism. When a projector is turned on or off, or when it reaches a certain state (such as entering or exiting standby mode), it can send a signal through a dedicated trigger output port. This port is usually a 12-volt trigger output, which can be connected to compatible devices such as screens, lifts, or even other projectors. The signal sent by the projector acts as a command, instructing the connected device to perform a predetermined action. For example, when the projector is turned on, it can send a signal to a screen to lower it into position, creating a seamless and automated viewing experience.
Types of Trigger Out Signals
There are primarily two types of trigger out signals: contact closure and voltage output. The contact closure type involves the projector completing a circuit when it is turned on, which can then trigger an action in a connected device. The voltage output type, more commonly found, involves the projector outputting a specific voltage (usually 12 volts) when it is turned on, which is then used to trigger the connected device. Understanding the type of trigger out signal your projector uses is crucial for selecting compatible devices and ensuring proper functionality.
Applications of Trigger Out
The applications of trigger out are diverse and can significantly enhance the functionality and convenience of a projector setup. Some of the most common applications include:
- Automating screen control: By connecting a projector to a screen via trigger out, the screen can automatically lower or raise when the projector is turned on or off, respectively.
- Controlling projector lifts: In installations where the projector is mounted in a lift, the trigger out can be used to lower or raise the lift when the projector is turned on or off.
- Synchronizing lighting: Trigger out can be used to control lighting systems, dimming or turning off lights when the projector is in use, and restoring them to their previous state when it is turned off.
Setting Up Trigger Out
Setting up trigger out on a projector involves a few straightforward steps. First, ensure that both the projector and the device you wish to control (such as a screen or lift) are equipped with trigger out and in capabilities, respectively. Next, consult the user manuals for both devices to understand the specific setup requirements, as these can vary between models. Typically, you will need to connect a cable from the projector’s trigger out port to the trigger in port on the device.
