The Raven M4x SNR Voter/Comparator takes advantage of the 476-150/151 module’s Signal-to-Noise Ratio
Analysis feature to synthesize a simple, software-configurable voting product. A Raven M4x SNR
Voter/Comparator is expandable simply by adding additional modules, and configuring those modules with the
Raven M4x Software.
Physical connection to an individual port is made via an RJ45 connector available on the front of the M4x
Blade. Each 476-150/151 4-wire RJ45 port has the following connections:
•
2 wires for analog receive
•
2 wires for analog transmit
•
2 wires for the PTT relay switch closure
•
2 wires for the COR input

There’s a USB port on the rear of the Raven M4x Blade. This USB port is used by the Raven M4x
Communication System Software to control and configure the M4x Blade. The M4x Blade is powered by a
source of 9 to 18VDC; the power connector is also on the rear of the M4x Blade. See Figure 3.
