Ramiaudio fdi1000   interface unit for various equipment for mixers and sound items (GPI, 5v etc)

FDI1000 is intented to solve all interface problems between various equipments.Itallows:  Interface of logical signals from mixing desk and sound machines.  Interface of GPI signal and sound machines.  Transforms 5V TLL to dry loops.  Sharing of dry loops.  Mutiplication of dry loops.  Insulation between control signal and equipment (really useful when theequipmentshaveacommonpotential).  Translate hold to pulse signal. The cell configuration usesfront panel dip switches. The configuration can be for only one cell or shared between more cells (LINK), allowing remote controlofseveralequipmentby thesameorder. A TEST facility, simulate an order, to check the cell settings, allowing problem detection. Two front panel leds show the cell state. Command input uses an opto coupler, working with dry loop or voltage (3 to 24V DC) A positive power supply and ground are available on the input connector.
