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
jack 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.

NOTE
Wi-Fi Access Point:
The internal Wi-Fi access point is not a high capacity Wi-Fi system.
If heavy simultaneous data usage is expected through Wi-Fi, it may
be best to use an external commercial Wi-Fi router connected to the
BDU’s LAN port.
