The GPI (General Purpose Interface) is a signal for synchronization that is produced by some consumer or professional equipments and that is transmitted to compatible equipments.
One of the most frequent uses that it does, concern the combining between an editing controller and a video mixer.
The responsible for the edition can for example make start a video transition or effect of the mixer in a determined established point.
The edition control unit will transmit the sync signal to the mixer through the GPI connection at the opportune moment.
The GPI Repeater, made by ELMAN, is an apparatus in a 2 unities container for rack 19" that contains inside 32 independent circuits each of which has an input and three outputs GPI.
Such outputs can control 3 different apparatuses, that have the necessity to receive contemporarily the same command (type on/off).
Being the 3 outputs electrically separate one from the other, he doesn't take the risk to damage the connected apparatuses; while if the apparatuses were simply connected in parallel, the differences of voltage in continuous between an apparatus and the other one could cause damages.
The GPI Repeater has 2 power supply circuits that work in parallel. In case of damage of one of the two (verifiable from the turning off of the led on the frontal panel), the operation of the apparatus is guaranteed by the second feeding circuit.
