Using the menu command ‘Device>Default settings’you can apply the factory settings to
the configurator.
MSD200 Configurator allows creating device configurations in online and offline mode as
well. The new configuration can be saved as a file and be used for configuring other
MSD200.
The status of each variable parameter or parameter row is indicated by its background
color:
pink
The parameter is not synchronized with the device parameter
(the parameter has been changed but not applied to the device)
grey
The parameter cannot be changed
Changing and reading of parameters are performed according to the diagram in Fig. 6.1.

To change the value click double in the
field and enter the value or select it from
the dropdown list. Confirm by pressing
enter.
A parameter witch is entered in the field is
checked for validity. If an invalid value is entered
the parameter will not be changed.
To read all parameters from a file use the
menu path ‘File>Load from file’, to save all
parameters to a file use the menu path
‘File>Save to file’.
To read all parameters from the device use the menu path ‘Device>Read all’.
Entry
To set all parameters
to default values use
the menu path
‘Device>Default
settings’.
To apply parameters to the device use the menu path ‘Device>Save all or ‘Device>Save changes’.
Reading
Fig 6.1
Alternatively you can use the toolbar items (see Table 6.1) and the buttons ‘Read’, ‘Apply’
and ‘Default’ for different parameter groups.
When you exit the program, all settings will be saved in an INI file. At program start all
settings will be restored from the INI file. At the first start or if the INI file cannot be found,
the program settings will be reset to defaults.
6.2. MSD200 –PC connection
►
NOTICE
When connecting MSD200 to a stationary PC, make sure that the computer pro-
vides grounding (this requirement does not apply to notebooks).
Use the dialog box ‘RS1 (PC) settings’ (see Fig. 6.2) to establish the connection between
the MSD200 and the PC. The content of the dialog box depends on the selected type of
connection. Perform following steps to establish connection:
Set the connection method:
oRS-232 –via the USB interface or RS1 (see 6.2.1)
oModem –via a modem (see 6.2.2)
connect the MSD200 to the PC
start MSD200 Configurator on the PC
set the network parameters in the Configurator
If the network parameters are correct, the connection will be established.
Use the button ‘Start / Stop’ to control the communication (see Fig. 6.2). The next item to
the right (colored circle) indicates the status of connection:
green –connection active
red –connection inactive

6.2.1. Connection via RS232
Fig. 6.3
1. Select a serial port. Appropriate port number can be found
in Device Manager under topic ‘Connections (COM and
LPT)’. If the device driver is successfully installed, a virtual
COM port will appear in the list.
2. Set up network parameters. Connection will be established
if the parameters of the device and in the configurator are
equal.
3. If parameters of MSD200 are unknown, set network pa-
rameters of the device and in the software to default. Set
switch ‘FACT’ on the front panel of the device to ‘ON’ posi-
tion for implementing factory settings, and click ‘Default’ in
the dialog box ‘RS1 (PC) settings’.
4. When the connection is established, save changes by click-
ing ‘Apply’.
6.2.2. Connection via modem
This type of connection can be used only when network parameters of the MSD200 are
already configured using RS232 connection (see section 6.2.1).
6.3. Channels
When the connection between the configurator and the device is established, the param-
eters of MSD200 are read out and device settings become available.
To configure the logging channels use the tab ‘Channels’ (see Fig. 6.5).
Fig. 6.4
1. Select a serial port. Appropriate port number can be found
in Device Manager under topic ‘Connections (COM and
LPT)’. If a driver is installed, a virtual COM port will appear
in the list.
2. Set up parameters of the modem:
SIM card telephone number (MSISDN) for connection
between the modem and the data logger
data exchange latency for mobile network (5000 ms is
recommended)
maximum number of retries on failed connection with
MSD200
3. Set up network parameters. Connection will be established
if the parameters of the device and in the configurator are
equal.
4. When the connection is established, save changes by click-
ing ‘Apply’.

Enable/disable data logging in case of error conditions (no data,
overload, line break etc.)
Extra logging if the measured value changes abruptly
The parameter specifies the maximum difference between the
measured value and the last recorded value to trigger the extra
logging. The extra logging is disabled if the Threshold is set to 0.
When used in the application, the Threshold should be trans-
formed into the data type specified in the parameter ‘Type’
Modbus function for request
0x03 (read holding registers)
0x04 (read input registers)
Register address for request
The possibility of data querying on several channels with one re-
quest
The channels with the same Group number (non-zero) can be
requested with one request. The grouped channels should use the
same network address, the same Modbus function and consecu-
tive Register addresses. Different data types are allowed.
Address bits for AKYTEC protocol request
8 or 11 bits
HASH parameter for AKYTEC protocol request
Index for AKYTEC protocol request
Can be set within the range -1…+32767
-1 means that the index is not used in the request
The logging process can be interrupted for up to two minutes, if channel parameters are
changed during an active logging (ARCH switch in ON position). In order to ensure the
data recording it is recommended to set the ARCH switch in OFF position before chang-
ing parameters.
6.4. File Manager
The tab ‘File Manager’ integrates all the necessary tools for operations with log files lo-
cated on the memory card (see Fig. 6.7): viewing the file tree, information about storage
capacity and free space on the card, copying files to PC, deleting files etc.
Fig. 6.7 File Manager
The tab is divided into 2 panes:
the left pane shows the file tree on the PC
the right pane shows the file tree on the memory card
A toolbar is located at the top of the window and contains the following controls:

It is not possible to poll the analog inputs in this mode.
Slave Ext mode
For Modbus RTU protocol only
Unlike the Slave mode the new line in a log file is generated with the period set in
the parameter ‘Logging cycle’ (see Table 6.6).
If the data from the master comes sooner than the period set, the data row will be
saved immediately to prevent data loss.
Spy mode
For AKYTEC protocol only
The device listens in on the network via the RS2 (DEV) interface to detect the re-
sponse to master’s request and performs the response data logging.
The configuration in Spy mode is similar to the configuration in Master mode with
the following exceptions:
oThe parameter ‘Query cycle’ is not used. The cycle is defined by the net-
work Master. Thus, the ‘Logging cycle’ should be adapted to the query
cycle of the Master.
oIf no data is received over a channel during the Logging cycle, the text
‘no data’ will be recorded in the log row for this channel, and the RS2 in-
dicator will change to red.
oThe parameter ‘Response time’ is not used.
The buttons ‘Read’, ‘Apply’ and ‘Default’ in the lower part of the window are used to con-
trol all parameter groups except the ‘Scheduled logging’, which has its own control but-
tons.

Polling period in Master mode
The parameter has no effect in Spy, Slave or Slave Ext
modes.
If all channels respond and the polling period for all
channels does not exceed the Query cycle, the RS2
indicator lights green.
If the real sum of polling times for all channels exceeds
the Query cycle, the RS2 indicator will turn from green to
yellow.
If at least one of the polled channels does not respond,
the RS2 indicator turns from green to red.
