Sync AG + BrightSign GPIO Setup Overview
Generic signal-flow overview for starting BrightSign video playback from a Sync AG using GPIO.
Use GPIO mode for this setup
When an audio guide action must start a BrightSign video, the Sync AG is used in GPIO mode. Do not treat this as a DIGI-only sync setup. GPIO is the control signal that starts the external video player. The video and audio still need to be prepared so they stay in sync after playback starts.
Understand the signal flow
The usual flow is: the visitor triggers a Point & Click action on the audio guide, the Sync AG sends a GPIO pulse to the BrightSign player, the BrightSign starts the video, and the BrightSign keeps a dry contact closed during playback so the Sync AG knows the video is running.
Connect the devices only after checking the model
Connect the Sync AG GPIO output to a BrightSign GPIO input. Connect a BrightSign GPIO output or dry-contact signal back to a Sync AG GPIO input if the setup needs playback-state feedback. BrightSign GPIO pinouts and adapters depend on the exact model, so verify the model-specific BrightSign documentation before wiring.
Program the BrightSign behavior
The BrightSign presentation must be programmed to start the correct video when it receives the GPIO trigger. It should also keep the configured dry contact closed while the video is playing, then release it when playback ends if that feedback is used by the installation.
Prepare and test the media
Use the Look2Guide video sync preparation workflow for the media files. After wiring and programming, test the full visitor flow several times: trigger from the guide, confirm the video starts, listen for sync, let the full video finish, and confirm the system is ready for the next visitor.
Do not use this as a pinout
This document describes the generic flow only. It is not a model-specific wiring diagram. Before installation, confirm the exact BrightSign model, whether a GPIO adapter is required, and the correct input/output pin numbers.
