3.4 Input source connections – Quad combo input
Mark II
About the Quad combo input Mark II
Due to demand from the market, Barco has created a second generation of the Input board to support 12G
input and throughput on the SDI connectors. From the release of this board onward, the Quad combo input will
be supported and will be the standard input board in every Input & Communication Unit, effectively replacing
the Mark I variant.
The updates on this new board include the following compared to its predecessor:
• SDI Input A now also supports 12G input signals.
• SDI Input C now also functions as a loop-through output for any signal placed on Input A .
• SDI Input D now also functions as a loop-through output for any signal placed on Input B .
• HDBaseT Input 1 now also supports network connectivity .
SDI Input & output – How does it work?
When connecting an SDI source to the projector and the signal is HD or 3G, you can choose any of the four
input connectors.
When connecting multiple projectors with the same signal, you can connect the signal as follows:
• Connect the source signal to Input A or B of the first projector.
• If the source signal is connected to Input A , connect Input/Output C to the Input of the following projector.
• If the source signal is connected to Input B , connect Input/Output D to the Input of the following projector.
• Continue in the same fashion until all projectors are connected.
When connecting a 12G SDI source to the projector, you can only connect that source to input A.
Only Input A accepts 12G SDI signals . While it is technically possible to connect a 12G SDI source
to Input B and connect that source to another projector in line (using Input/Output D), this first
projector itself will not be able to process the 12G signal.

Spotting the difference between the Mark I and Mark II Input boards
Since there will be projectors in the field that have the Mark I Input Board and others that have the Mark II
input board, it is important to know the difference between the two variants.
