H2NS Environmental Inc was formed in 1994. The founders of H2NS are the previous founders of Odessa Engineering.
Experience in the environmental data acquisition field is depicted in the figure on page 2.
Early on, H2Ns Inc. was contacted by many Odessa Engineering clients in order to obtain support for their Odessa Hardware
and software. Through word of mouth we built a reputation of rapid response with reasonable rates and soon had a
respectable customer base. We performed system expansion and upgrades on existing Odessa systems.
The original designers of the Odessa data logger, the DSM series, set out on a quest to design and produce a data
acquisition unit capable to meet today’s challenges and flexible enough to meet the unknown after Y2K.
The environmental instrumentation manufacturers of today have harnessed the power of a central processing unit (CPU) and
imbedded it into their instrumentation. This modernization produced features previously unavailable to an operator. Now
diagnostics could be run over a serial port, set-up or set-up changes made with a keystroke, digitized data was available for
direct download into a database. However, there was one drawback. All manufacturers had different protocols, hence the
digital data download could not be automated.
H2NS Inc. recognized this sign of the future and began designing a data acquisition device with the capability of
communicating with an array of manufacturers instrumentation and combining that data into a common database.
This concept also allowed operators, at a remote location, to communicate with an individual instrument to perform
diagnostics and routine “state-of-health checks. The capability to perform this type of testing led to “Predictive Maintenance”,
where an operator could envision a failing instrument component, perform maintenance and restore the instrument before it
failed completely. While connected the CPP-3794, data collection continues uninterrupted while an operator is exercising
inherent features of an instrument. As not all users had 100% new-smart instrumentation but rather a mixture of old and new
so we implemented an analog front end for the CPP-3794 in order to maintain backward compatibility.
Our software package, DataLink/AQM is intended for the ambient market. It can be used to monitor a process, where
rapid data sampling and graphical presentation is required. The plus feature of DataLink is that it will communicate with
Odessa data loggers. this provides a cost savings to clients because the data acquisition units do not need to be
replaced. The DSM is not leap year compliant (2004). Another plus benefit of DataLink is that when and if the DSM
becomes insupportable, it can be replaced by the CPP-3794. This replacement is transparent to DataLink.
Our Objective
We took the next step in data collection by utilizing the
“Smart Features” designed into today's state-of -theart instrumentation to provide comprehensive and cost
effective products for data acquisition applications

“On-The-Fly”
This module performs the physical polling of the
CPP 3794 or Odessa DSM that is gathering the
environmental and process related data. It also
performs the data computations for long term data
points, such as the Lbs. per Hour data and even
totals such as the Lbs. or Tons per
day/month/qtr/year.
It displays viewer selectable data points in real
time. It also displays alarms and allows for alarm
acknowledgment with reason and action
statements. Data gathered can be displayed in
tabular and trend graph view. Polling of individual
data groups can be controlled. Communications
between the data loggers can be monitored in real
time. Data Monitor can produce, on demand,
current calibration and current and historical alarm
reports. If required, Custom Screens that are
customer configurable are available.
The Next Slide Shows a
Typical Data Monitoring
Screen.
This powerful program is used to report data gathered
using the Data Monitor program. Data values and
statuses may be viewed may be viewed and edited.
Data can be from polled data groups, analyzer
calibration drift tests and alarms. Various standard
reports are available as well as the powerful fullfeatured Ad-Hoc query manager for making customized
reports. The Ad-Hoc Query Maker is a powerful tool for
creation of custom reports.

Automatic Report Agent (Scheduler)
The Automatic Report Agent is provided as a means to
schedule report generation on a regular basis. Alarm,
calibration or summary reports may be scheduled to
write to a "Text File" or "Print" to a specified printer. The
Automatic Report Agent can be used to run reports
already configured in Data Explore, or create new
reports.
Refer to the next slide to view the
“Scheduler” set up window.
Data Backup is part of the DataLink
family of programs. Data Backup
will automatically backup data,
alarm, calibration and configuration
files. Files are backed-up in a “Zip
File” format.
Two separate back-ups
are run as scheduled:
•Data and Alarms
•System Configuration
and Calibrations
Data files can be copied or
deleted on demand using the File
Maintenance utility.
