program and in the device are equal, connection will be
established.
2. If the device network parameters are unknown, set the
network parameters in the device and in the program to
default values:
– set DIP-switch FACT on the front panel of the device
to ON (Tab. 2.1);
– click Default to set the network parameters in the
program to default values;
– click Apply.
3. If you know only the baud rate of the device COM port,
you can use the button Scan by speed to find the device
in the network.
4.2.2 Modem connection type

4.3 Channels
To configure the logging channels, use the tab Channels (Fig. 4.5). There are 64 logging channels
at your disposal.
NOTE
Before changing the parameters in “Channels” tab, it is recommended to set the DIP-
switch ARCH to OFF to stop logging. If not, the device may pause the logging by itself
for up to two minutes to accept the new parameters and some data can be lost.

4.6.1.1 Mode overview
Master
– Polling and logging data from the analog inputs and all Slaves connected to RS2 interface.
Slave
(see App. B. for example of configuration)
– Logging the data, received from Master using the function 16 (Write Multiple Registers).
– Logging the measured values of analog inputs is unavailable.
– Required settings:
–Channels tab (Sect. 4.3):
♦Logging
♦Channel
♦Type
♦Decimal point
♦Register address
–Settings tab, RS2 settings pane (Sect. 4.6.1):
♦Device address
♦Response delay
Slave Ext
– As slave mode, except for the logging period, which in this mode is defined in the Logging cycle
parameter (Tab. 4.6).
– If the data from the master comes sooner than the set period, the data row will be saved
immediately to prevent data loss.
Spy
– The device listens in on the network via the RS2 interface. If it detects the response of another
device to master’s request, it performs logging of the response data.
– Logging the measured values of analog inputs is unavailable.
– The configuration in Spy mode is similar to the configuration in Master mode with the following
exceptions:
– The parameter Query cycle is not used, the period is defined by the Master. Thus, Logging
cycle should be adapted to the query cycle of the Master.
– If no data is received over the channel during Logging cycle, the string “no data” will be
written in the log row for this channel, the RS2 indicator will change to red.
–Response time parameter is not used.

4.6.2 Digital signature
The pane is used for log file integrity control.
The digital signature is intended to check the integrity of the log file after removing the memory card
from the data logger or copying files to PC.
Use the parameter Digital signature to enable / disable the digital signature.
To create a digital key, proceed as follows:
Fig. 4.9
Generated key
1. Set Digital signature to ON to enable the feature.
2. Click Generate to generate a key.
3. Click Save to MSD200 to save the generated key in the
device (saving takes 20...60 seconds).
4. Click Save to file to save the key to a file on PC.
5. Click Apply to initialize the key.
Manually specified key
1. Select ON to enable the feature
2. Enter the desired key (1…16 characters) into the fields Key and Confirm key.
3. Click Save to MSD200 to save the generated key in the device (saving takes 20...60 seconds).
4. Click Save to file to save the key to a file on PC, or just write it down.
5. Click Apply to initialize the key.
The key cannot be read from the device memory.
The digital signature is formed in the log file on the memory card (Sect. 5). This occurs when the
data from the RAM buffer are transferred to the memory card and takes up to 60 seconds when the
device is on.
4.6.2.1 Check log file integrity
The log file created on the memory card is protected by a digital signature. To check the integrity of a
copy of the log file on your PC, proceed as follows:
1. Establish connection between the logger and the program.
2. Open File Manager tab.
3. Click Refresh to update the file trees on both panes.
4. Select the file on the memory card (right pane).
5. Select the target folder on the PC (left pane) to which the file will be copied, and click Copy.
6. Select the copied file and click Check signature.
7. In the open dialog box, enter the key previously saved in MSD200.
Fig. 4.10
Click the ellipsis button to search for a key file previously saved on the PC, select it and click OK.
If it is a manually specified key, you can optionally enter the noticed key into the input field.
The message “Digital signature matches” appears if the log file copy has not been changed.
