Take  your  tablet  or  smart  phone,  go  to  the  WiFi 
settings  and  select  the  Edu-Logger  network 
which matches the 900-268 Module ID found on 
the  back  of  the  900-268  device.  (Edu-
LoggerXXXX for example). 

8.

 

Give your device about 20 seconds to connect to 
the 900-268. 

9.

 

Once the device is connected, go to your browser 
and  type  the  website 

wifi201.com

  into  the  URL 

bar, then wait for 30-60 seconds. 

10.

 

You  will  see  a  “Control  mode”  icon  in  the 
browser, click on this icon. 

11.

 

The  browser  will  then  load  a  new  screen  and 
begin to auto detect the sensor(s); this can take a 
minute. (You can stop the search when the sensor 
is found.) 

12.

 

If the browser does not auto detect the sensor(s), 
select “Search for sensors”. 

13.

 

Once the sensor is found you will see an icon on 
the left side of  the screen  for the  salinity  sensor. 
The icon will display real time data. 

14.

 

Click  on  the  “Module  setup”  button  located  on 
the salinity sensor icon in the module window to 
change the salinity probe settings if need be. 

15.

 

Click  on  the  experiment  set  up  button  to  change 
the  experiment  settings  if  need  be  (Experiment 
duration for example). 

16.

 

To  run  an  experiment  and  collect  data,  select 
“On-Line” experiment, then select "Run". 

17.

 

If you have a newer generation 900-268 (with the 
USB icon on the cover) this can be used as a 900-
213,  meaning  you  can  tether  the  probes  directly 
to  the  computer  using  the  900-268.  To  engage 
operation  in  this  fashion,  press  3  times  on  the 
panel  key.  Repeating  this  operation  will  return 
the unit to WiFi mode.
