Presets
An advanced preset management system allows the creation, storing, and recall
of 80 presets within the VP‑8
iP
itself and an unlimited number on a host PC. All
signal-processing parameters are contained in these presets, allowing the preservation
of the complete processing environment. Optionally, Input and Output settings may
be stored and recalled with presets.
Note that all VP‑8
iP
presets are mode-based. That is, presets are stored along with
data that remembers what operating mode was running at the time they were created.
Preset Encryption
Presets are encrypted using the VP‑8
iP
internal 128 bit serial number as the
encryption key.
Onboard Real-time clock
A highly accurate internal real-time clock allows the automatic recall of presets
at pre-determined times. This clock may be set to free-run or be synchronized to an
external on- or off-site SNTP server, or it may by synchronized to the GUI PC.
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
limiting resistor for voltages above 3.3VDC.
Ethernet Interface
The VP‑8
iP
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
VP‑8
iP
.
Software Remote Control
Supplied Windows® VP‑8
iP
GUI software affords control of all system and
processing parameters via a 10/100BaseT Ethernet interface.
