Impulse 8126 - Manual (Page 15)

SeaDAC Lite Power Requirements
Sealevel SeaDAC Lite modules are powered by the USB host interface and require
5VDC @ 500mA to be available on the USB port. Most computers and powered
USB hubs are capable of meeting this requirement, while passive USB hubs and
some laptops running on batteries may not. Check the product manual that shipped
with your system or hub if you are uncertain. Sealevel technical support may also be
able to help.
The maximum power requirements for each SeaDAC Lite device are shown below.
