DataClient - Terminal software for CHM 15k
84 Revision R09, November 2016
11.8 Service & Software Update
The DataClient contains no longer a firmware update feature. Please use the
web-interface of the WAN/ LAN or DSL interface for firmware updates.
There is an additional button “get all parameters” on this page. All parameters of
the CHM 15k will be saved into the local text file. Its name is displayed automat-
ically after you pressed the “get all parameters button.
“Merge Raw” writes the sequential acquisition of the NetCDF raw data files to
disk. It is possible to switch off this function.
11.9 General available controls or indicators
At the bottom line of the window there are three light indicators:
– RS485 send: Normally this light should only blink for a short moment,
while sending commands. An exception is a running software update,
where large blocks of data will be sent to the CHM 15k, in this case this
light shines for some seconds.
– RS485 receive: This light shines while receiving data from CHM 15k. Dur-
ing this period send actions (like set/get variables) must not be done
because there is only a half-duplex RS485 connection to the CHM 15k,
so simultaneous sending and receiving is not possible.
– RS485 check sum: Each answer of CHM 15k (telegram or set/get com-
mand confirmation) is closed by two checksum bytes (complement of
two). The result of check is indicated by this light: green - ok / red - fail-
ure.
There are two buttons in the upper right corner of the program window:
“end session”: The current session is finished, and the very first start dialog (with
RS 485 connection parameters) appears again. Now possibly changed connec-
tion values should be filled in and another session can start.
“stop”: The program terminates.
11.10 Autostart and command line parameters
The file “Autostart_DataClient.cmd” allows an automatic startup procedure of
the DataClient software. The default path variables listed below are used to have
a seperate path for the measuring software, the data and configuration files,
which is not restricted by the Windows operating system. The standard file
includes all command line options, which can be changed due to user require-
ments:
set CHMDIR=%systemdrive%\Lufft\Programs
set MPATH=%systemdrive%\Lufft\Measure
