Overview

The Optic USB Base Station allows communication between
the host computer and HOBO optic loggers. The base station
uses infrared light to transfer data, which allows loggers to be
completely sealed and waterproof. The Optic USB Base
Station converts the USB communication protocol into an
infrared protocol used by the optic USB loggers.

A coupler is required to connect the logger to the base station.
Refer to the documentation that came with your logger for the
part number of the correct coupler.

Supported Loggers

This model of the Optic USB Base Station supports HOBO
U-Series loggers with an optic USB interface. Contact your
Onset Authorized dealer or the Onset website
(http://www.onsetcomp.com) for more information about
compatible loggers and couplers.

Installation

1. Plug the USB connector on the base station into an

available USB port on your computer.

2. Firmly insert the optical end of the base station into the D-

shaped end of the coupler, as shown below.

3. Insert the logger into the coupler, aligning the logger as

described in the documentation that came with your logger.

Thank you for purchasing an Onset Optic USB Base Station.
With proper care, it will give you years of reliable service.

The base station’s LED will illuminate when the logger is able
to communicate with the computer.

If the logger is not aligned properly, or if the coupler is not
seated firmly on the base station, the logger and the Optic
USB Base Station will be unable to communicate.

Operating Tips

• This base station is water-resistant. It is splash proof, but

it is not designed to be immersed or operated under water.

• Strong sunlight may interfere with communications. If the

base station does not seem to be working, try again in a
shaded area.

• Remove the logger from the coupler when it is not

communicating with the computer. Storing the logger in
the coupler may cause the logger’s battery to run down
prematurely.

• Do not take the Optic USB Base Station apart. There are

no user-serviceable parts inside.

®

• This Optic USB Base Station requires HOBOware

later to launch and read out data. For detailed software
instructions, refer to the HOBOware User’s Guide.

• The Optic USB Base Station will operate at temperatures

of 0° to 50°C (32° to 122°F). The device can be safely
