P3 video installations
In a Martin® P3 video display system, you supply a chain of VC-Feeders
with video data from a P3 video processor via a combined P3 video and
48 VDC power supply device such as a Martin® P3 PowerPort.
Input cable
To connect a chain of VC-Feeders to a DC power and P3 video data
source, you must use a Martin® P3 Hybrid Input Cable shown in Figure 5.
Hybrid P3 Input Cables have:
• a 4-pin male XLR connector that accepts DC power and P3 video data,
and
• a 6-pin female M16 or BBD connector that connects to the VC-Feeder's
IN connector.
