ADU - 102 amplifier - distribution unit

    Print Manual  
Main Feautures:

Device ADU-102 is used to amplify and also to duplicate
signal NMEA 0183 versions 1 and 2 to several receivers.

Also ADU-102 can be used for other signals transmitted
through interfaces RS-232 and RS-422/485 amplification
and distribution.

Particularities: device's small weight and small overall
dimensions.

 

Technical Description:

  • 2 inputs with active channel automatic
    or manual selection.
  • Optoisolated inputs(up to 1000 V)
  • 7 outputs (4 are galvanic isolated)
  • Baudrate: up to 56 000 bps
  • Output for the active input channel indication.
  • Data receiving/transmittion and current
    active channel indication.
