Communication
protocols Serial port 1: Native (CISS) for instrument configuration, internal clock date/time setting,
data download (instantaneous and elaborated measure values and diagnostic informations);
GPRS transmission support (TCP or FTP mode).
Serial port 2: Native (CISS) as serial port 1 or one of each protocol supported by E-Log
(specific E-Log model depending): CISS LSI LASTEM probes, TTY, Modbus, Gill etc.
Measures elaboration Statistical algorithms for arithmetic and vectorial elaborations, uniquely programmable for
each measure, calculated on single time base, from 1 second to 12 hours, for all measures.
