4. INSTALLATION
4.1. INTRODUCTION
In this section the instructions for the mechanical fastening of the MEC-100 and its electrical connection are provided.
4.2. MOUNTING
The MEC-100 case is suitable for both on-board machine mounting and panel mounting.
See Fig. 4.2.a.
4.3. SERIAL COMMUNICATION AND PRELIMINARY SET-UP
The MEC-100 is equipped with an RS-232 serial port located on the card component side: it consists of a DB-9 female
connector. For the connection to Personal Computer (see Section 5 for the MEC-100 Interface System setting instructions) a
standard communication cable ending with a DB-9 female connector is required. In Fig. 4.3.a the provided pin-to-pin connection
is shown.
DB-9 Male Port
If the DB-9 serial port is not available on PC, one of the USB ports must be used, paying attention to:

Interpose an USB/DB-9 adapter between the standard cable and the PC.

Install the adapter driver files on PC (please follow the provided instructions).
It is possible to set the MEC-100 parameters only if the MEC-100 is properly supplied, as described in Par. 2.1.
The MEC-100 is properly supplied if connected to a working generator (operating at rated voltage and rated frequency),
according to the provided connection diagrams, or supplied from an external supplier. It is always advisable to supply the MEC-
100 with the minimum voltage values included into the allowed supply voltage range (see Par. 2.1). It is strongly recommended
to not supply MEC-100 with voltage values > 240Vac.
