Day-Parting and Long-term Scheduling
A weekly preset scheduling establishes a weekly cycle of preset changes, allowing
for automatic programmed day-by-day exclusions or additions.
Additionally, a separate long-term scheduling table permits the establishment of
one-off preset changes for any future time and date.
General Purpose Input (GPI)
Eight optically isolated inputs are slaved to the first eight preset slots.
Presets may be recalled by providing the appropriate voltage to the associated
GPI port to create a Logic High and may be either momentary or latching as desired.
Voltages are applied between the appropriate GPI pin and Common with the GPI pin
being the most positive voltage. Please see manual text for the required current limit-
ing resistor for voltages above 3.3VDC.
Ethernet Interface
The FM-531HD contains an auto-sensing 10/100BaseT Ethernet switch with one
port available on the outside of the unit for field use. Because the switch is auto-sensing
it is not necessary to utilize a crossover cable when connecting a PC directly to the
FM-531HD.
Software Remote Control
Supplied Windows® FM-531HD GUI software affords control of all system and
processing parameters via a 10/100BaseT Ethernet interface.
