SIU Aux Port
The 10-pin Aux port on the integrated SIU allows users to expand WBMS capabilities by integrating
additional sensors. For the full pin description, refer to the appendices at the end of the manual. The
Aux port can connect to an additional WBMS to operate in a traditional dual head configuration with
either sonar projecting down, or one looking forward for obstacle avoidance in challenging
environments. This port can also communicate with the iLiDAR, a topographic laser, to
simultaneously collect multibeam and topographic data. For further information on these options
please contact NORBIT.
