The OM-320 portable data logging
system consists of the OM-320 system
base, a choice of plug-in interface
modules and icon-based Windows
software. Several optional accessories
including modem modules and PCMCIA
data memory modules are also
available. The OM-320 system base is a
latching weatherproof enclosure
containing the microprocessor, data
storage memory, analog to digital
converter, liquid crystal display,
batteries, input/output terminal strip
connector and six interface ports that
accommodate the interface modules
and accessories.
The system base is programmed for
operation via the included Windows
based software. Simple to complex
programming is readily implemented by
developing the program visually on the
PC by dragging and dropping icons and
interconnections, then transferring the
program via RS-232 or modem to the
OM-320 memory before deployment.
Alarming, conditional logging, algebraic
data manipulation and a multitude of
other functions are easily accomplished
with this visual programming software.
Six interface ports, providing up to
24 analog and/or digital channels are
accessible by removing two
thumbscrews and lifting the hinged
OM-320 front panel. Each port can
accept interface modules ranging from
four channel universal Vdc modules
(software configurable for six
thermocouple types, 15 ranges of volts
dc or amps dc) to four channel digital
I/O modules (software configurable for
frequency, event, counter input, digital
output), to PCMCIA data memory
modules, to 14.4 KBaud modem
modules and more.
Analog interface modules with full
differential inputs, software
programmable gain and configuration,
included front-end completion circuitry
and rugged suppression protection
circuitry insure reliable accurate signal
conditioning. The OM-320 has an
enhanced self-calibration feature that
includes user programmable selfcalibration cycles for both interface
modules and the system base analog to
digital converter. Precision trimmed,
temperature stabilized references insure
accurate self-calibration performance
over time and temperature.
Designed for portable, plant floor
and long-term remote data collection
applications, the OM-320 incorporates
low power CMOS circuitry and extensive
energy conserving circuitry. The
OM-320 will run for up to one month
from its six internal alkaline D-cells.
The D-cells are readily accessible in a
lid mounted battery holder providing for
quick and easy field replacement. For
longer term logging applications, low
voltage external power can be directly
connected to the system base. In the
event of external power failure, the
OM-320 will automatically transfer to
the internal batteries provided
uninterrupted logging.
OM-320 Portable Logging System, $1300,
shown smaller than acutal size
The OM-320 front panel includes user
control buttons for Enable, Stop, System
Status display, Power and Output Relay
override. Additionally, a two-line liquid
crystal display is provided for real-time
data display of actual and calculated
input signal readings as well as
providing detailed system status
reporting ranging from battery state of
charge to current mode of operation to
display of user programmed alarm
messages. Front panel LEDs can be
user programmed for status and
alarming applications.
Included in each OM-320 system base
is a general purpose digital input that
provides a user programmed event or
counter input, two alarm relay outputs,
three TTL level digital alarm outputs and
a cold junction compensation sensor for
thermocouple measurements or general
purpose temperature input. Input and
output wiring is uniquely handled
through the use of a terminal strip
adapter (TSA) board which allows for
mass connection and disconnection of
wiring while maintaining the integrity of
the sealed enclosure. Through the use
of the terminal strip adapter, an OM-320
can be quickly disconnected from its
associated I/O wiring harness, moved to
another site and reconnected to a new
set of I/O wiring.

OM-320 Interface Modules
OM-320 interface modules plug
directly into one of the six interface
module ports in the system base
logger and provide various functions
ranging from digital and analog
signal input to alarm and digital
output to special applications such
as modem and PCMCIA memory
card interface
Analog and digital interface modules
allow for direct connection and data
recording from a full spectrum of
input signals and sensor types.
Various modules provide excitation,
filtering, transient protection,
amplification and software codes as
required by the connected
sensor/transducer or sensed
parameter. True differential inputs
with precision instrumentation
amplifiers insure high signal to noise
ratio performance.
Special function interface modules
available include modem interface
modules and PCMCIA memory card
modules. Modem interface modules
incorporate FCC approved modems
supporting direct telephone line
connection for remote interrogation
and control of the OM-320 as well
as advanced functions such as
alarm paging. The PCMCIA memory
card interface module allows for
data collection to a removable
"credit card style" memory module.
This memory card provides massive
data storage capability and can
easily be removed and replaced in
the field.
Interface modules plug directly into
one of the six interface module ports
OM-320 Windows Software
The OM-320 system base includes a powerful multi-purpose Windows software package
that facilitates serial communications, datalogger programming, real-time data display,
collected data graphic display and data export to other applications. Direct RS-232 and
telephone modem communications are handled with a communications screen. To
establish a connection between the PC and the datalogger, just click on the serial link
icon. This visual communications implementation allows for quick and simple
communications between the PC and a connected OM-320 for status, collected data
downloads, programming and remote control.With the OM-320 software a program is
developed graphically on the PC using icons and interconnects and is then transferred
to the OM-320 memory. The OM-320 is then ready for standalone logging and
disconnected and enabled for operation from its new program. Programming the OM-320
is simple and is a three-step process:
can be
in the system base logger allowing
for standard I/O wiring through the
terminal strip adapter on the system
base logger. Each interface module
contains encoded information for
immediate self-configuration. Upon
installation of the interface module
into the OM-320 system base, the
microprocessor reads the module
type and stores calibration
information for use during readings.
The interface modules are then
configured for application and signal
type via the icon based visual
programming method in the OM-320
Windows software. Interface
modules include front end
completion circuitry, such as
4 to 20 mA burden resistors and
voltage dividers, thus minimizing
field requirements for interfacing
real world signals.

OM-320 Serial Communications
OM-320 Program Net
After data has been acquired in the field by the
OM-320 and downloaded to the PC via modem or
RS-232 link, the software's powerful graphic data
plotting tool can be used to graphically plot up to
seven data channels vs. time. Data analysis is
enhanced with
mouse stroke
zooming and a full
spectrum of
display options
including X and
Y-axis scaling and
formatting, grids,
cursor data
display, symbols,
instant
min/max/average
and integral view
analysis and more.
Graphic Data Display
1. Query the OM-320 for its current hardware
configuration (installed modules and
accessories) via a serial link connection.
2. Visually develop the OM-320 program by
dragging and dropping icons onto the
program development screen from the
toolbar and add interconnection lines.
Individual icons are configured by doubleclicking on the icon and completing the
pop-down dialog box. Upon completion,
save the program to disc and return to the
communication screen.
Complying with the
Windows standard, plots
generated from within the
OM-320 software can be
printed directly or saved as
*.BMP files (Windows bit
map format). The *.BMP plot
can be seamlessly
integrated into other
Windows applications
including word processors
and spreadsheets allowing
for powerful report generation. The software also includes
additional post-processing options including collected data
conversion to ASCII columnar (text) files and direct output to
the Microsoft Excel spreadsheet format.
The OM-320 software also provides a real-time, scrolling
display of data collected by the OM-320 on a serially
connected PC screen. This is an extremely valuable tool for
critical real-time process monitoring as well as serving as a
quick method of checking on OM-320 I/O values and status.
3. From within the OM-320
communication screen, drag the
created program icon from the virtual
PC to the virtual OM-320. The
program is automatically error
checked and transferred to the
OM-320's memory and is ready for
deployment and data collection

OM-420 Expanded Feature Model
The OM-420 is an expanded feature
model of the OM-320 portable data
logging system. The OM-420 consists of
the OM-320 system base, plug-in
interface modules, standard Windows
software and any user-specified
accessories along with an
OM-220-RPS-1 Rechargeable Power
Supply housed in a NEMA 4X (IP66)
rated enclosure. The OM-420 was
designed to meet the needs of remote
data logging applications where power
is unavailable for excitation of sensors
and transmitters. Additionally, the
OM-420 is ideal for data collection
installations at unattended sites with
no available grid power. The
OM-220-RPS-1's two rechargeable
gell cell batteries are readily recharged
via photovoltaic, wind or other power
sources.
Integral to the OM-420 is the
OM-220-RPS-1 Rechargeable Power
Supply. Two user programmable power
supply outputs are available which can
source seven different regulated voltage
levels from 3.5 to 22 Vdc. Outputs are
short circuit/over-current protected. The
two power supply outputs can be
independently programmed for output
voltage as well as operational mode.
Two modes are available; Continuous
ON and Automatic Operation. In
Automatic Operation, the power supply
is under control of an optically isolated
low voltage (5 Vdc, 0.5 mA) control
input signal. This control input interfaces
directly to any of the datalogger's three
digital outputs which can then provide
intelligent cycled power to the field
transducers/transmitters under control
of the software program. This cycled
power technique maximizes the
OM-220-RPS-1 battery life. The
OM-220-RPS-1 can also be used as a
rechargeable power supply for the
datalogger.
