H2NS Environmental Presents the CPP-4794 - The Next Generation
Serial Data Collection
The CPP-4794 represents the next generation of data logging
and offers serial
interfacing to instruments as well as supporting the traditional
analog approach using an
analog to digital converter. Over a single RS-232 cable, the
CPP can collect data,
status and control the calibrations of connected instrumentation.
simplifies wiring, documentation and increases system reliability.
In those instruments
that support a time/date download, the CPP keeps the entire
system time synchronized.
Pass Through to Instruments
The CPP-4794 also offers an unabated pass through mode that
allows a user to make a
direct connection with an instrument that is connected to the
CPP, passing signals
through the CPP, unabated. This allows manufacturer supplied
diagnostic routines to be
conducted on instruments from a remote location, e.g., your
facility or even the
instrument manufacturer’s facility. The CPP continues
to collect data from all other
12 Independent Serial Ports
Up to 12 independent serial ports can be installed in the CPP.
One serial port is used
for an on site operator, another is used to communicate and
transfer data to a central
polling facility. The remainder of the serial ports can be
used to interface to
instrumentation. One of the ports can be used to provide a
Modbus output from the
CPP, or other special protocols, as needed.
The battery backed, internal memory in the CPP can store over
3,000 data values for ten
channels. For hourly averages, this translates into 3,000 hours
of data for ten channels.
However, given all that can happen at a remote location such
as power surges,
brownouts, lightning, and operator mishaps, the CPP also offers
data storage on a
64meg, industrial grade, Compact Flash Memory Card. This provides
degree of buffering from circumstances that can affect data
collected and stored on site.
Years of hourly data can be stored on the Compact Flash Memory
