MANUAL OVERVIEW
This User’s manual provides information relative to the use of the OMP-MODL
Portable Data Logging Systems manufactured by Omega Engineering. The manual
is organized into sections describing the main components of a OMP-MODL system,
from the System Base through the various features within the provided software.
The last section of the manual consists of the Appendices which give detailed
specifications and information for general reference and advanced applications.
After following the instructions for the installation of the HyperWare software, much
can be learned by exploring this manual, the software and the hardware in any
order... without concern for damaging results. However, it is HIGHLY
RECOMMENDED that this User’s manual be read in its entirety before deploying the
OMP-MODL in a real application.
A note on the keyboard / mouse convention used within this manual... Throughout
the manual, instructions on PC keyboard entry or menu selections via mouse are
specified by using italic print such as ENTER which refers to the `Enter’ Key on the
keyboard or FILE which refers to the menu item titled `FILE’.
OMP-MODL SYSTEM: `THE BIG PICTURE’
The OMP-MODL is a battery powered portable data logging and control system. It
can be left at a site to collect data from various analog and digital signal or sensor
inputs. This data is mathematically processed by the OMP-MODL and stored in its
internal memory while simultaneously performing basic onsite alarm functions. The
collected data is then transferred to a PC running the supplied HyperWare software
for data plotting, real-time trending and analysis.
OMP-MNL VS OMP-MODL
The OMP-MNL is a special fixed functionality model of the OMP-MODL family. The
OMP-MNL offers the same functionality as the basic OMP-MODL with the exception
that it cannot be expanded with the addition of Interface Modules.
Throughout this manual, references made to the OMP-MODL generally refer to the
OMP-MNL and the OMP-MODL except where noted.
OMP-MODL SYSTEM COMPONENTS
A OMP-MODL portable data logging system consists of a number of components...
both hardware and software.
The main components are listed below and details follow:
♦OMP-MODL System Base
♦Interface Modules
♦HyperWare™ , Windows based software
♦Options such as modems, PCMCIA, etc

OMP-MODL System Base
The OMP-MODL System Base refers to the main data logger unit composed
of a stack of two interconnected modules... the MLCPU-1 module and the
MLAD-1 module. These two modules combined house the main
microprocessor and support circuitry, memory, power supplies, A to D
converter as well as 6 inputs (4 analog, 1 Cold Junction Compensation
temperature and 1 digital) and 4 outputs. The System Base can be used
stand-alone as a 6 input / 4 output data logger (OMP-MNL) or expanded with
the addition of Interface Modules, battery packs, and/or display modules.
The System Base includes a connector bus that provides signal connections
to the added Interface Modules.
Interface Modules
Interface Modules (See Figure 1... -2) are add-on layers that provide the
interface to various types of inputs and output signals. The Interface
Modules can be User installed onto the System Base then configured for the
specific type of signal or sensor to be connected to the OMP-MODL.
Interface Modules are configured via software and/or switch settings on the
modules.

USING THE OMP-MODL 1-3
A family of Interface Modules is available for interface to various input signal
types such as thermocouples, RTD’s, voltage, current, frequency, event, etc.
Additionally, Interface Modules are available with outputs for digital alarm
and basic ON/OFF control functions.
Note that the OMP-MNL model does not support installation of additional
Interface Modules.
HyperWare™ Software
Utilized with the OMP-MODL is a powerful Windows based software
package called HyperWare. HyperWare, running on an IBM compatible PC
under the Microsoft Windows environment provides a multitude of functions
for setup of the OMP-MODL as well as analysis of collected data including:
♦Serial Communications support between the PC and the
OMP-MODL for RS-232 and telephone modem links
(OMP-MNL does not support modem comm)
♦Programming of the OMP-MODL using the powerful
HyperNet™ visual icon based programming method
♦Multi-channel, graphic data display of previously
collected data using HyperPlot™
♦Screen captures of HyperPlot graphs for seamless
integration into other Windows based software
applications such as wordprocessors, spreadsheets, or
desk-top publishing packages
♦Conversion of collected data files to ASCII text or
Microsoft Excel file formats

Additional Components
Special function modules are also available to provide:
Telephone Modem Interface - plug-in modules that contain integral
low power 2400 Baud or 14.4 Kbaud telephone modems. These
modules allow for direct connection to standard telephone lines for
data transfer, reprogramming, and control...all from a remote PC
running HyperWare (not supported by OMP-MNL model) .
PCMCIA Memory Card Interface - plug-in module provides a
socket and interface circuitry for removable PCMCIA memory card
support. When utilized, the OMP-MODL stores data to the credit
card sized PCMCIA card. At any time, the card can be unplugged
from its socket and carried or shipped to a another site where the
data can be downloaded to a PC. Advantages of the PCMCIA card
include massive data storage capability, easily transportable data,
field data collection by non-technical staff, and reprogramming of
field units via card.
Battery Pack - add-on module containing 6 alkaline D-Cell batteries
for installations without power.
Front Panel Display and User Switch module - plug-on module
provides a faceplate with 2-line LCD, full set of User switches and
Status indicators.
Special Serial Communications Interface - a variety of special
serial communication types and protocols are available for serial
signal interface. Contact Omega Engineering about your specific
application requirement.

SUMMARY OF STEPS IN UTILIZING THE OMP-MODL
In a typical application of the OMP-MODL portable data logging system, the
following sequence of steps would be involved. Details of each step are presented
in later sections of this manual.
1. Install the required Interface Modules into the OMP-MODL
System Base. Configure Interface Module hardware switches if
applicable (eg enabling a front end divider for the +/-30VDC
range on the HLIM-1)
2. Connect a serial cable link between the OMP-MODL and your
PC. Launch HyperWare and establish the connection.
HyperWare will automatically configure for the detected logger
model (OMP-MNL, OMP-MODL, or HyperLogger). Then change
to the HyperNet Development Screen.
3. Query the OMP-MODL for its current hardware configuration by
clicking the NEW button.
4. Construct a Program Net for this logging session by dragging
and dropping icons onto the HyperNet screen, then connecting
signals between the icons. Save the Program Net to disk and
print out a Terminal Strip Adapter wiring diagram for field
reference.
5. Transfer the Program Net to OMP-MODL memory via the serial
link and disconnect the serial link.
6. Install the OMP-MODL at the site and make the appropriate
wiring connections to the I/O Terminal Strips and modem (if
used).
7. Enable the OMP-MODL, then as a quick pre-departure check,
check readings at various pre-programmed Program Net nodes
using the Next and Select buttons while viewing the OMP-MODL
display.
8. Leave the OMP-MODL to collect data.
9. Later, connect up to the OMP-MODL via a serial link (RS-232 or
modem) or retrieve the PCMCIA memory card and from within
HyperWare, download the OMP-MODL memory to a file on the
PC.
10. For a fast and immediate review of the collected data, double-
click on the data icon and HyperPlot will automatically load and
graphically display the collected data.
11. Save the desired HyperPlot graphic view as a Windows Bitmap
file , then switch to your Windows based wordprocessor and
seamlessly insert the saved graphic into your test report.
12. Optionally, use the HyperWare Post-Processing capability to
configure a special data reduction/ conversion icon network.
Then run the collected data file through the post processor and
generate a text file, Excel Spreadsheet file or another HyperPlot
file.
