GPIO function transmits Tally Light

GPIO function transmits Tally Light

The first presentation of the new GPIO function live and in action is being given by G&D at IBC. The function enables users to transmit relevant Tally Light information to a remote workstation and to indicate the active ‘on air’ system.G&D Matrix systems give several users access simultaneously on the same computer, or on different computers in studios or OB vans.

The company describes a situation in which the computer is ‘live’ on a programme and a producer is making undesired changes on this system. The big advantage – that the computers are externalised by KVM and various systems can be made flexibly accessible – has until now had one disadvantage, it said.

On the remote computer, there was an on-air signal, typically in the form of a Tally Light, so additional technology and much expense was required to also show this at the workplace.

Thus, it was not only the distance that needed bridging, but the Tally controller also needed to know on which computer the user was situated.

G&D has developed a specially customised function for such cases to transfer the GPIO status. The GPIO changer is also said to make technical installation easier. Tally switch states are transmitted from the computer via the KVM matrix and the information is made available to the user at the console.

The connected ‘ON AIR’ light informs the producer when a computer is live on a programme.
