Mounting the Eprom
The Eprom - separately supplied - contains the application program.
When inserting the eprom into its socket (see page 4) pay attention to align its polarity correctly (the
notch on the eprom must coincide with that of the socket). Insert the eprom carefully without
bending or breaking its small pins.
Ver. 1.0 dated 21/10/94
The clock card - necessary to display current time and date - must be
directly inserted into the main card through a plug-in connector. The clock
card is necessary to provide a time-zones control action. In the event of
power supply failure to pCO, the clock card will be powered by a lithium
battery for more than one month. For connection to the relative connector
(6) see page 4 above.
Code MNEWCLOCK0
The RS422 serial card allows pCO to be network connected into local or
remote supervisory and telemaintenance systems. For connection to the
relative connector (8) see page 4 above.
