Here is info on how to connect to the 3 dataloggers through the wireless router.

192.168.1.1 Router IP
root   admin

250m logger IP 192.168.1.132
100m logger IP 192.168.1.107
Tower base logger 192.168.1.105

sonic sonicuser
su sonicroot

minicom -s in PUTTY terminal window will allow you to configure the serial port
need to be root
Have to change serial ports
Data collection programs shouldn't be running
minicom will start
ctrl A A starts linefeed

On 1/15/2008 Dan checked cabling into 250m logger and found that the 200 and 300m loggers we
switched from what the diagram from UMass indicates. Table below reflects that. Note 300m sonic
has lots of bad points as compared to the 200m sonic

250m

This is according to Vince's and Mario's drawing

N = north boom   S = south boom

ipconfig is a command to look at IP and network information
ntpq -p will check if the GPS is working and the clock reference

etc/ntp.oncore.o contains the GPS initialization information

ps -fx will show is collection programs are running (sonic)

nohup run_sonics_250  & starts data collection in background with the ability to logout
run_sonics_100m
run_sonics_10m

Can use winscp to collect data from raw_data directories.
Because file names aren't unique at each level, you need to save them in separate directories.


Hi Dan,

I am attaching a schematic of our setup that is valid for the period 8/11-8/27.
Hopefully it clears some of the confusion.
From the data and notes I have, only 6 sonics ran during July: sonics 1-6 on the 100m logger.


See BaoTowerSetup_Aug2007_001.jpg file for numbering diagram.
