5.3.3. Establishing a Communication Link
Before configuring or monitoring the regulation system parameters you must establish a communication link between MEC-100
and MEC-100 Interface System.
To establish a communication link between MEC-100 and MEC-100 Interface System you must:

Verify that the connection between MEC-100 and Personal Computer has been established as described in
Par.5.2.

Start the MEC-100 Interface System software as described in Par. 5.3.1.

Click on the Open Comm button as shown in Fig. 5.3.3.a.
Fig. 5.3.3.a
Connection Button
To select a PC communication port other than the default, execute the following operations:

Click on the Tools item in the menu bar of the MEC-100 Interface System (see Fig. 5.3.3.b).

In the displayed pull-down menu, select the Port Configuration item.

A window (see Fig. 5.3.3.c) appears where the desired communication port can be selected (from 1 to 99).
After establishing the connection, the MEC-100 Interface System configuration parameters, initially set to zero by default, are
automatically updated to the values saved in the MEC-100; these last can correspond to the default values, if the regulator is set
for the first time, or to those stored in the E
The communication initialization and the update of the regulation system parameters may take a few seconds. In
view of the correct execution of such operations, it is recommended to wait until they are completed before entering
any data.
You can connect to MEC-100 only when current is properly supplied to its power terminals; in order to communicate
with the device microprocessor, in fact, the latter must be powered and in operation.
5.4. PASSWORD MANAGEMENT
After starting the MEC-100 Interface System and establishing the connection, the System Monitoring section is operative and
shows the value of the regulation system electrical quantities on a real-time basis. In the System Parameters section the values
of the system parameters stored in the MEC-100 are displayed: they can correspond to the default values in case of first
configuration or to those saved during a previous configuration operation.
Immediately after establishing the connection to the MEC-100 or after 5 minutes from the last use of the MEC-100 Interface
System, the System Parameters section appears to be write-protected: it is therefore necessary to remove the write protection
by entering a password. Here below the password management modes for the MEC-100 Interface System are described.

5.4.1. Entering Password

To remove the write protection of the MEC-100 Interface System and enter the password:

Click on the Enter Password button, placed at the left bottom of the main screen, see Fig. 5.4.1.a.

Enter the password in the field of the displayed window (see Fig. 5.4.1.b).
The default password is
