3.5. Communication with the device
Parameter setting and transmission of measured data can be done either remo-
tely via the server and GSM/GPRS network as mentioned in the previous chap-
ter, or locally via cable from a connected PC (laptop)
The local connection of the Hydro Logger H1 to a PC or laptop can be made using
the KP232/M8 communication cable.
On the PC side, the cable is connected via
a nine pin connector to the RS232 port. If
the PC or notebook is not equipped with
an RS232 connector, it is necessary to add
a USB/RS232 converter (a suitable type of
converter can be ordered together with
the communication cable from the device
manufacturer).
On the side of the H1 unit, the M8 con-
nector is located in the lower right corner
of the unit for cable communication.
After connecting the HydroLogger H1 to a
PC (notebook), the MOST program can be
used to perform a complete setup of the
instrument parameters, reading archived
data from the instrument memory and
saving them to a file, as well as visualizing
the actual measured values from the con-
nected sensors and transducers.
A certain limitation for the communica-
tion between the PC and Hydro Logger H1
is the fact that this communication cannot
be established while the GSM module is
switched on in Hydro Logger H1. Howe-
ver, since the GSM module is rarely swit-
ched on when sending measured data to
the server, this limitation does not play a
significant role when setting parameters.
Connecting the pins of the M8 communi-
cation connector:
The USB/RS232 converter is used to convert
signals between USB and RS232 interface for
newer types of PCs and laptops without
RS232 serial port
