Communication modes 

 
M-Log  has  got  different  communication  devices,  that  can  be  used  to  extend  the  connection 
capacities and modes to systems for data collection: 

 

 

RS232  serial  port:  at  least  one  port  (equipped  with  a  double  connector  for  applications 
where  you want to interface M-Log with  a DCE device or a  DTE device) for each M-Log 
datalogger;  two  serial  ports  are  available  for  ELO008  and  ELO009  models;  (see  §

Errore. 

L'origine riferimento non è stata trovata.

 

Xxx  line  driver:  it  lengthens  the  cable  for  serial  connection  up  to  1  km  or  more;  the 
connection speed is function of covered distance; you have always to install a couple of line 
drivers: one of them must be connected to RS232 serial port of M-Log, the other one must 
be connected to PC; 

 

RS232/Ethernet  converter  (code  LSI  LASTEM  DEA550):  it  can  be  used  with  instruments 
equipped  with  RS232  serial  line;  it  allows  the  communication  using  Ethernet  LAN/WAN 
net, so virtually of any length; particularly ELO007 model has this converter built-in;  

 

GSM  DEA714  Modem:  it  uses  GSM  network  for  connection  to  remote  instruments;  9600 
bps connection speed; it can be connected to serial port of M-Log; (see §

Errore. L'origine 

riferimento non è stata trovata.

 

GSM/GPRS  Modem  (code  LSI  LASTEM  DEA717  and  DEA718):  it  uses  GPRS  packets 
transmission in order to allow the permanent transmission (with transmission rate according 
to choice) and rating according to traffic; it can be connected to serial port of M-Log and it’s 
an  application  valid  only  for  datalogger  equipped  with  terminal  board  (series  ELO007  e 
ELO008); (see §5.6.2) 

 

Bluetooth Adapter (code LSI LASTEM DEA300): it can be connected to serial port of M-
Log (it’s advisable use port serial 1, as able to handle sending large data frames, in excess of 
128 B); 

 

External radio devices. 

 

5.6.1

 

RS232 serial port 

 
M-Log communicates with PC through 9 poles male/female not-reversing serial cable. 
 
M-Log implements a particular system for activation of communication port: after 8 seconds of no-
reception  or  no-transmission,  the  consumption  goes  down  to  first  saving;  after  further  22  seconds 
the  consumption  goes  down  to  minimum  values.  If  you  don’t  query  M-Log  continually,  it 
communicates using very low energy consumption.  
 
Every  instrument  uses  a  net  address,  that  consists  of  a  number  with  value  included  between  1 
(default)  and  200.  If  the  instrument  has  been  connected  through  network  (radio)  with  other 
instruments, it’s necessary to modify the address. The PC programs use the address of each definite 
instrument to select M-Log for sending of communication messages.  
 
M-Log is compatible with LSI LASTEM sensors family equipped with CISS protocol. So it can be 
used in existing networks of LSI LASTEM cordless sensors, that make reference to E-Log, R-Log, 
Babuc  ABC  or  receivers  connected  to  PC  directly.  In  this  case  M-Log  can  be  programmed  for 
spontaneous  transmission,  through  serial  port,  of  instantaneous  data  of  acquired  and  calculated 
measurements;  this  parameter  is  available  in  mask  for  modification  of 

3DOM
