  • Page 3: Safety Information

    Safety information Do not make any changes to the electrical circuits of the PCB. When making any changes the hazardous voltage might cause an electrical shock, fire or injuries. Turn off the power at the main switchboard before installing the buffer. Product failure and injuries may be caused when power is tuned on during installation.

  • Page 4: Description

    Description The MP2x8i NMEA Buffer has been designed to distribute NMEA or other RS422 signals from one transmitter up to 8 listeners. The transmitted signal is galvanically isolated from the power supply and all listeners. The unit can operate with signal speed up to 230400 bps and power supply range from 9 to 36 VDC.

    Terminal description Power and signal connection for hardware rev_1.0 and higher. X1: Power and NMEA input connection PWR + power positive PWR – power negative Grounding NMEA1 + input 1 NMEA1 – input 1 Grounding NMEA1 + input2 NMEA1 – input 2 X2: Outputs connection NMEA out 1 A NMEA out 1 B...
  • Page 6 Single input transmission with auto switching: Figure 3: Single input transmission with auto switching Auto mode works as a regular buffer with 1 input and 8 outputs. It has automatic switching to input 2 if input 1 stops to receive the data (signal loss).
  • Page 7 Dual input independent transmission mode: Figure 4: Dual input independent transmission mode Dual Input Independent Transmission mode works as two independent buffers with 1 input and 4 outputs each. Signals from input 1 and input 2 are not mixed and independently transmitted to the outputs. LED (red) operating mode: Input 1 LED and input 2 LED will blink both (not simultaneously), depending on the transmission time of the input source.
