I have a sensor which transmits water level data through an optical cable to a device translates the data to a USB.

I want to replace the 300 foot optical cable with a XStick.
The remote sensor is self powered and the translator is USB powered. I can provide a battery pack at the remote m location.
The software at the laptop reads the data through COM port5.
The device can be seen here.

and here

The cost of the telemetry cabling we want to replace is about $300.
