OMNIA MPX NODE MANUAL
12 Rear Panel
5 ports make up the MPX Node rear panel and are described here, going left to right.
Composite
This BNC connector provides FM composite Input or Output, depending on whether
your MPX Node is configured as an Encoder or Decoder. MPX Node operates at standard
levels: 3.5V peak-to-peak, low source impedance.
GPIO
This DB15 female connector provides 5 input and 5 output contact closures, which should
be wired according to the diagram below. Closures are opto-isolated, and require a 5vdc
power source. Functions of the pins are under software control, and may be assigned
in the GUI GPIO section. While the DB15 connector is the same as that used in Axia
xNodes, the pin layout is different for MPX Node.
