    Single Cable Setup

    Description

    Distributes up to 2 NMEA data input streams to 4 or 8 optically isolated RS422 outputs. Galvonic isolated Power input provides 1kVdc isolation to prevent ground loops. Extra outputs provided for Daisy chain to another data buffer.

    Features

    • 2 independent isolated NMEA or RS422 Inputs.
    • 8 x RS422 Optically Isolated outputs.
    • 1Mbps High Speed.
    • Isolation voltage for NMEA input 5kV
    • 10-45 V DC.
    • No microprocessor intervention.
    • Input indicator LED’s
