LSI LASTEM M-Log – User’s manual
14
The instrument can be programmed; however only the
baud rate
and
network address
can be
changed; all other parameters cannot. The rate can be programmed from 1200 to 115200 bps; in
case of use of phone modem GSM/GPRS it is suitable program 9600 bps on bound rate.
Electrically speaking, both ports are configured as a DCE device. The following table shows the
meaning of each serial connectors' pin:

Modem power supply
M-Log can power the modem continuatively (through 12 Vdc powering from the terminals, like
shown at §3.3.1), or through timed actuator, in order to reduce the electric energy consumption of
the system.
You must use actuator n.3 to power the modem through actuator. Activate it according to the
different connected modem:
GSM Modem: the actuator is started at time of instrument starting; in this case the telephone
connection holds on also during the remote re-configuration of the instrument through
3DOM
program; the next shutdown happens by means of the timed actuation logic,
according to the programmed shutdown time; i.e. in case of following programmed timed
logic, starting at 15:00 o’clock and shutdown at 16:00 o’clock, if the instrument is started at
14:30, the effector will operate one hour and half;
GPRS Modem: the actuator is started at time of instrument starting and the shutdown
happens about one minute later; next modem activation will happens according to the GPRS
data transmission timing, as programmed with
3DOM
.

Configuring the operative mode
The instrument supplied by LSI LASTEM is equipped with standard configuration that includes
only the battery tension and the internal temperature; for models series ELO009 it’s possible to set-
up the configuration automatically, as they are equipped with function for sensors auto-recognition;
but configuration of models ELO007, ELO008 and ELO011 must be set-up by means of 3DOM
software, through the direct input from software library or through support of suitable models
designed for different user applications (microclimate, walls transmittance …)
Both the measurements autogeneration and the applicative models produce the generation of only
type “
Ave
” elaborations (mean value). When configuration is set-up starting from sensors in 3DOM
library, it’s possible to obtain the generation of more complete processings (“
Min/Ave/Max”, “Tot”,
“Stdev”, “%valid data” …
); so in this case it’ll be possible to delete, manually, the elaboration you
aren’t interested in.
