Ouster OS0 - Interface Box

The following graph Voltage at connector vs cable length can be used as a guide to determine the
appropriate input voltage to the sensor connector for your desired cable length. The values on the
graphwerecalculatedusing idealizedcableresistancesderivedfromtheAWGsystemandassumed
maximumpowerdrawfromthesensor.
