Communication
Parameter setting in the station and transmission of measured data can be done either
by cable from a connected PC (laptop) or remotely via a server and GSM network.
MOST PROGRAMME
All communication between the H40 and the connected PC (laptop) is done via the
MOST program. Using this program, you can, for example, parameterize the station,
transfer measured data from the station to the connected PC or view the current meas-
ured data. The MOST program is described in detail in chapter 4 of this manual.
Parameterization of the station consists in creating the current parameter file for the ap-
plication and then saving this parameter file to the H40 station. The MOST program is
also used to archive the current station parameter file and to modify this file. A special
server function can transfer the parameter file from the server via GSM/GPRS data net-
work to the H40G station even remotely.
After purchasing a license for the MOST program, the user gets an unlimited time option
to upgrade the program.

GSM/GPRS COMMUNICATION MODULE
The H40G telemetry station contains a GSM/GPRS communication module that usually
mediates all data transmissions between the station and the user. Connecting to the sta-
tion from a PC (laptop) is therefore usually not necessary.
Measured data stored in the station is automatically transferred via GPRS network to the
database on the server at the specified time. Conversely, a parameter file is transferred
from the server to the station if any changes to the station parameters are needed. The
parameter file is transferred at the end of the data session and only if the user has changed
at least one of the parameters and placed the new parameter file on the server. The MOST
program is used to manage the parameter file.
CONNECTING A PC (LAPTOP) TO THE H40 DATA
LOGGER
Transfer of measured data from the H40 station to a con-
nected PC or setting of parameters in the H40 station can
also be done from a PC (laptop) connected to the station
with a 2 m long KP232/M12 communication cable.
On the PC side, the cable is connected via a 9-pin con-
nector to the RS232 port. If the PC or laptop is not
equipped with an RS232 connector, it is necessary to add
a USB/RS232 converter (a suitable type of converter can
be ordered with the station).
On the side of the H40 unit, the K1 connector type M12 is
used for cable communication.
