5. MEC-100 INTERFACE SYSTEM
5.1. INTRODUCTION
The MEC-100 Interface System provides an interface tool between the MEC-100 and the user capable of:

Providing a user-friendly and intuitive working environment for the setting of the regulation system parameters.

Displaying in real time the electrical data of the system controlled by the MEC-100.

Allowing the system status control.

Enabling the storage of the complete set of system parameters in the form of program files or text files.
5.2. MEC-100 PRELIMINARY SETUP AND INSTALLATION OF THE MEC-100 INTERFACE SYSTEM
MEC-100 is equipped with an RS-232 serial port located on the component side of the board, consisting of a female DB-9
connector. To connect it to a Personal Computer you will need a standard serial communication cable, terminated with a female
DB-9 connector, to be plugged into the relevant PC port.
Should the PC not be equipped with an RS-232 serial port, use the USB port, taking care of:

Interposing a male USB/DB-9 adapter between the serial cable and the USB port.

Installing on the PC the drivers supplied along with the adapter (follow the instructions provided by the manufacturer).
Fig. 5.2.a shows the wiring diagram you will have to follow for the preliminary setup of MEC-100. You will have to perform the
following actions (in the specified sequence):

Connect MEC-100 to the PC through the serial cable.

Power the board, by supplying voltage to terminals P1 and P2. The supply voltage can be anywhere between 30Vac and
240Vac.

The aluminium support of MEC-100 must be connected to GROUND.
FOR THE PRELIMINARY SETUP OF MEC-100 DISCONNECT ANY CONNECTED CABLES AND POWER THE
BOARD FROM A SOURCE OTHER THAN THE GENERATOR. The only connections must be the ones shown in
Fig. 5.2.a.
WARNING: Should you have to physically intervene on the MEC-100 and/or perform any setup operation,
never forget that if the regulator unit is powered, the upper section of the MEC-100 regulation panel (on the
connection site) is subject to a lethal voltage. Any operation resulting in direct contact with the regulator
board must be performed when the unit is not powered.
The CD-ROM provided together with the MEC-100 system includes the utility for the installation of the MEC-100 Interface
System software and the user and maintenance manuals (User Manual) of the regulation system.
