the “
View
” button, in the dialog box select the
DRIVERS
folder, press the “
Continue
” button, when the warning
“
Installing a device
” appears, press “
Continue anyway
.”
4. The virtual COM port ”
CDC USB to UART
” is installed; press “
Finish
.”
5. The system then detects and installs the “
Mass storage device
” -> “
ATMEL MASS STORAGE USB Device
” -> “
Disk
drive
.”
After the installation is completed, the recorded is listed in the system as a virtual COMx port (x-port number: 1, 2,
...) and two exchangeable disks: internal memory 4 MB with the AR234 label and SD/MMC memory (available after
the card is put in the “SD/MMC CARD” slot). In the internal memory the configuration text file
AR234.cfg
can be
seen (chapter 9).
NOTE
:
Do not disconnect the device from the computer before the installation of drives is completed and whenever the
device is connected again to the USB port when disks are being detected (when the
[READ/WRITE]
LCD is on; see
chapter 5).
8. INSTALLATION OF SOFTWARE
In the "
SOFTWARE
" folder of the CD-ROM that is provided with the device there is a free software installation set
for the recorder. The set contains the following applications:
-
ARSOFT-CFG WZ1
- display of current measurement data, battery voltage, and date and time;
- configuration of the real time clock (
RTC
) and other parameters, such as type of
measurement input, ranges of indications, recording options, alarms, display, access options
etc. (chapter 9), the software requires communication with the recorder via the USB port -
on-line configuration
-
ARSOFT-WZ3
- presentation, in a graphic form or as text, of results, with the possibility to print; input data
is uploaded one time from a “csv” text file created in the internal memory in the recorder or
on an SD/MMC card (chapter 11)
The latest
versions of the aforementioned programs are also available at the website (www.apar.pl). The detailed
descriptions of the aforementioned applications can be found in the installation folders.
9. SETTING OF THE CONFIGURATION PARAMETERS
All the configuration parameters of the recorder are stored in the non-volatile FLASH internal memory in a text file:
“
AR234.cfg
.”
When the device is switched on for the first time, an error message may be shown in the display due to the lack of
a sensor or the fact that the sensor that is connected is not one that is factory-programmed. In such an event, the
proper sensor or analog signal must be connected and the configuration must be programmed.
There are parameter configuration methods:
1.
Use the USB port and the ARSOFT-CFG WZ1 software (
on-line configuration
):
−
connect the recorder to a computer port and to start the ARSOFT-CFG WZ1 application
−
after the connection has been established, the current measured values, the battery voltage, and the
internal time and date of the recorder are displayed in the software’s window;
the “
STATUS
” LED indicates
the presence of transmission
−
setting and viewing of the device parameters is possible in the parameter configuration window
−
new parameter values must be approved with the
Approve changes
button
−
the software enables synchronization of the time and the date with the computer
−
the current configuration can be saved in a file or set using values read from a file
−
the recorder updates the
“cfg”
configuration file after it is disconnected from the USB port of the computer
(provided that battery voltage > 3 V)
