into receptacle in bottom of HWI-LV24. The 4 Series
Processor has battery-backed memory and timeclock
devices. The battery provides power to these devices
during power outages and other temporary power
interruptions. In vacation homes and other residences
which are not continuously occupied, the 4 Series
processor MUST be powered by a circuit that is never
turned off even when the residence is unoccupied.
11.Turn power ON. Restore the supply breaker to the ON
position.
12. Connect Serial Link. Connect a standard DB9 male
connector to the Link 3 RS232 connector on the
processor for system programming or communications
with other equipment. A standard serial cable (not a null
modem) is required for programming the system via the
serial port using a laptop. If the processor is connected
to a modem, a null modem adapter is needed between
the processor and the attached modem.
13. Connect Ethernet Link. Connect a standard RJ45
connector to the Link 9 Ethernet jack on the processor
for system programming or communications with other
equipment. A crossover cable is required for
