Highlighted Features

    Reads out data from systems in the field for transfer to a host computer
    Optionally relaunches the data logger — synchronizes the logger’s clock with the shuttle’s clock and (in most cases) sets logging to begin at the next interval
    Preserves data in nonvolatile memory, even if batteries are depleted
    Displays logger status, including memory, battery level, and sensor readings
    Displays its own status, including clock, memory, and battery level
    Lets you change the batteries in the field without resetting the clock
    Allows you to test individual smart sensors

Requirements:
USB cable (provided); compatible logger with appropriate cable and/or base station
U-DT-2: HOBOware 2.6 or greater

Compatibility: HOBO U30 series systems, HOBO Weather Stations (H21-001) and Micro Stations (H21-002 only), and HOBO Energy Logger systems
Firmware upgrades: Available on the Onset website as needed to provide compatibility with future supported logger models
Operating temperature: 0° to 50°C (32° to 122°F)
Storage temperature: -10° to 50°C (14° to 122°F)
Time accuracy: ± 1 minute per month at 25°C (77°F); see Plot A

Logger-to-Shuttle Transfer Speed
USB: 64K in approximately 30 seconds
Serial: 512K in approximately 60 seconds

Shuttle-to-host transfer speed: Full shuttle offload (4 MB) to host computer in 3 to 5 minutes, depending on computer
Data capacity (full loggers): 4 MB (minus 64 KB for shuttle information): enough for 7 readouts of 512K loggers
Idle timeout: Shuttle powers down after two minutes of idle time, except when actively communicating with HOBOware (see HOBOware User’s Guide for details) or changing logger batteries (10 minutes)

Ports: 
RJ-12 jack for communicating with smart sensors
Mini-B full speed USB port for communicating with host computer
Full speed USB port for communicating with U-Series loggers and base stations
High speed serial port for communicating with serial loggers
Shuttle communicates with only one device at a time
