The HOBO U-DT-2 U30 Shuttle Data Transporter provides convenient in-field data offload and relaunch of HOBO U30-NRC systems and HOBO Weather Stations (H21), Micro Stations, and HOBO Energy Logger Pro systems(H22). The U30 Shuttle's 2 x 16-character display shows current readings (for selected loggers), and logger status.

The HOBO U30 Shuttle performs the following major functions:

Reads out data from systems in the field for transfer to a host computer
Optionally relaunches the 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
Environment: Indoor,Outdoor
Measurement: N/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)

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.
