LSUW – Underwater LAN-Switch

LSUW

The LSUW is an underwater LAN switch and power supply for up to 4 SENSYS MX3D UW data acquisition units. It can also be used as standalone Ethernet switch for up to 5 generic Ethernet devices.

Description

The LSUW - LAN Switch underwater - has been created to connect up to 4 MX3DUW 5-channel data acquisition units. This way you can build underwater systems with up to 20 FG3MD UW sensors, needing only one uplink to the Top Side Unit or ROV MUX.

A fifth output allows connecting any Ethernet device and supply power to it. Even though the system was created to daisy-chain SENSYS DAU’s, the usage of the LSUW is not limited to connect SENSYS equipment.

It can be used to provide power and LAN to up to 5 connected devices. The internal processor is supervising the outputs and enables the power supply only if a consumer is detected. The LSUW is reporting the actual current consumption of all outlets as well as the state to a UDP socket once per second.
