parameters, and it’s called
automatic transmission rate
. In this mode M-Log results like LSI CISS
multi-channel sensor and so its measurements can be received by an other M-Log.
In addition to the CISS protocol, M-Log is able to manage, through serial port 2, other protocols:
TTY (see §5.6.4);
Modbus (see §5.6.5) ;
Gill anemometer;
Giletta GIL-D-I Ice sensor (only if it’s required);
Aeroqual gas analyser;
Hydrolab;
Lufft UMB sensor (only if it’s required);
Climatronics sensor.
A GSM or GPRS telephonic modem can be connected to serial port; in this case, if you want reduce
the energy consumption of modem, it’s possible follow the instruction of §5.7. Anyway, if removed
appropriately, the use of a modem doesn’t block the local communications with M-Log, connecting
PC to serial port of instrument directly.
Note
: in case PC has to execute any communication with the instrument through serial port, and the
latter has been programmed for spontaneous transmission of data at frequent rate (intervals shorter
than 10 s), PC could meet some difficulties to start first communication; so it could be necessary to
start operation several times. After the reception of message, M-Log deactivates spontaneous
communication for 1 minute, in order to make further communications with PC easier.
M-Log manages the flow check according to two choices (none, only RTS) that can be selected
through configuration from 3DOM (see §4.4.4.3 of manual SWUM_00339 inside CD of LSI
LASTEM – MW6501 products).
