Product Information

Full details

The Blackmagic Design GPI & Tally Interface is designed for multi-camera production environments, providing a reliable way to signal which camera is 'on-air' to your crew and equipment. Its key benefit is the expansion of tally capabilities for ATEM switchers and Videohub routers via simple contact closures. A potential caveat is that it requires a compatible ATEM switcher or Videohub for full functionality and relies on Ethernet for connection.

FAQs

How many tally outputs does one unit provide?

Each Blackmagic Design GPI & Tally Interface provides 8 contact closure tally outputs.

Can I connect more than 8 tally outputs?

Yes, you can connect multiple GPI and Tally Interfaces together via Ethernet to expand the number of available tally outputs.

What type of connection does it use to connect to an ATEM switcher?

It connects via Ethernet to your ATEM production switcher.

What operating systems are supported?

It supports Mac OS X 10.8 Mountain Lion and later, and a wide range of Windows operating systems from Windows 7 onwards.

What is the power requirement?

The unit requires a 12V DC power supply.

Does this interface work with non-Blackmagic switchers?

This interface is specifically designed to integrate with Blackmagic Design ATEM switchers and Videohub routers.

What are 'contact closure' outputs?

Contact closure outputs are simple electrical switches that can complete a circuit when activated, commonly used to trigger indicator lights or other simple devices.

Troubleshooting

No tally signal is being sent.

Verify the Ethernet connection to the ATEM switcher. Ensure the ATEM switcher is powered on and configured correctly to output tally signals. Check that the contact closure connections are secure and wired correctly to your tally indicators.

Interface not recognized by ATEM switcher.

Confirm the Ethernet cable is functioning and properly connected. Restart both the GPI and Tally Interface and the ATEM switcher. Check the IP address settings if manually configured, or ensure the switcher is set to automatically detect the interface.

Tally lights are not turning off when switching away.

Review the tally output configuration within the ATEM switcher software. Ensure the correct tally mode (e.g., Program/Preview) is selected. Test the contact closure outputs directly with a multimeter to confirm they are functioning as expected.

Multiple interfaces are not cascading correctly.

Ensure all interfaces are connected via Ethernet and powered on. Verify that the network configuration allows communication between the devices. Consult the ATEM switcher's documentation for specific instructions on daisy-chaining multiple tally units.
