DIP-switch and LEDs
The LT-1000 NRU has a built-in DIP-switch, which is accessible from the bottom side of the unit, before the
pole or roof mount is mounted. To access the DIP-switch, the cap plug has to be removed; hereafter the
installer will have direct access to configuration of the DIP-switch. Furthermore, two LEDs are available on
the bottom side of the LT-1000 NRU. The placement of the DIP-switch and LEDs are illustrated in Figure 30.
The configuration of the DIP-switch is illustrated in Figure 31.
IMPORTANT: The DIP-switch is configured to 4.800 baud (NMEA 0183) and ‘Open’ (NMEA 2000) when
leaving the factory. However, the installer should always check the settings of the DIP-switch
prior to an installation. Make sure to hold the LT-1000 NRU as illustrated on Figure 30, when
reading and configuring the DIP-switch, to avoid wrong settings.
The color code and description of the LEDs are illustrated in Table 4.
