5.1.3   Logging Data  

 

If the Micro SVP Sensor has been configured with the “Logging Option”, the instrument 
will  have  the  capability  of  storing  data  in  its  non-volatile  memory.  A  typical  logging 
sequence would be as follows. 
 

 

Connect the Micro SVP to a computer via the communications cable (If not 
connected through an external battery pack then 12 VDC power must be applied 
through the data/power cable) 

 

Using a terminal program, establish communications with the Micro SVP 

 

Program the instruments logging parameters 

 

Unplug the communication cable from the Micro SVP.  Connect the Micro SVP 
to the external battery pack and insert the red shorting plug into the battery pack. 

 

Deploy and recover the instrument 

 

Remove the shorting plug and connect the instrument to a computer via the 
communications cable (If not connected through an external battery pack then 12 
VDC power must be applied through the data/power cable) 

 

Use ISS or SmartTalk to download the data.  A terminal program can also be 
used, capture the logged data by using the Micro SVP’s DUMP command 

 

Note:  The  Micro  SVP  Sensor  will  not  log  data  into  its  memory  unless  the 
instrument’s  SV  sensor  detects  that  it  is  in  water  and  the  shorting  plug  is 
inserted into the battery pack. 
 

5.1.4   Using Integrated System Software (ISS) 

 

Integrated System Software is a comprehensive, MS Windows 95™ based program that 
allows  the  user  to  program  the  instrument,  view,  log,  edit,  graph,  analyze,  export  and 
print  the  data  from  multiple  instruments.    Refer  to  the  ISS  on-line  help  for  detailed 
instructions on the use of this program. 
 

5.1.5  Using SmartTalk 

 
SmartTalk  is  an  easy  to  use,  MS  Windows  95™  based  program  that  allows  the  user  to 
program the instrument, view data, log data to the computer’s hard drive, and export data 
for use in other programs such as MS Excel™. 
 
Refer to the SmartTalk manual for detailed instructions on the use of this program. 
 

5.1.6  Using a Terminal Emulation Program 

 
Terminal  emulation  programs  (such  as  HyperTerminal,  ProComm  or  Commo)  can  be 
used to communicate with the Micro SVP Sensor.  The terminal emulation programs can 
communicate  with  RS-232  equipped  Micro  SVP  Sensors  or  with  the  Smart  Network 
Controller to communicate with RS-485 Micro SVP Sensors.   
 
Connect  the  Micro  SVP  Sensor  to  a  serial  port  on  the  computer  (refer  to  section  4.2).  
Launch the terminal emulation program and select the communications port to which the
