Below Deck Unit (BDU)
The Below Deck Unit (BDU) supports voice and data communications in a marine
environment. The BDU is capable of supporting wireless voice and data that links the user with
the Iridium satellite network. As a wireless access point, the BDU provides Wi-Fi (802.11)
access for data and Voice over IP (VoIP) calls. Three RJ-45 Ethernet connectors and one RJ14
connector enables the user to tether directly to the BDU, if desired. The Management Portal is
a graphical user interface that can be used to modify system settings and indicate system status.
The BDU is powered by either an AC/DC power supply or a DC power cable with a 10-32V
input range and remote start wire accommodating all types of marine vessels, applications and
power sources.

satellite connection and the Wi-Fi.
