The default window is the Channels window:
Figure 3-15. Channels Window
3.4.1 Overall Program Structure
The Omega program uses a tabbed structure for setting up the sensors and
configuring/viewing the data. Clicking on the Channel Config, Channels, or
Logging tab opens the respective windows.
• Channel Config window: The location where all the parameters are set up for
each sensor, such as sample rate, filters, etc. These parameters impact how
information is displayed or recorded by the functionality of the other two
tabs.
• Channels window: A grid of zero to twelve channels that display a digital
readout of the sensor output.
• Logging window: Data for up to 12 sensors is stored in individual .csv files for
post analysis.

Software
3.4.2 Channel Config Window
The Channel Configuration Window controls all of the channel-specific
parameters, and some global parameters. Some parameters are changeable
elsewhere. Only sensors that are connected to the computer will be present in
the Channel Config window. The following describes the content of the
Configuration Window cells. Defaults will be applied to sensors which have not
been connected before. After configuring a sensor, the software will retain the
sensor settings that are present when the sensor is disconnected or when the
program is closed. If changes are made to rows 5, 7, 8, 11, and 13-16 while the
sensor is being logged, this will result in a Yes/No prompt box appearing: “Are
you sure you want to change the _______? Logging operations that involve this
channel will automatically be stopped.” Clicking “Yes” will apply the change,
clicking “No” will revert back to the value before the change.

Figure 3-17. Channel Configuration Window
1) Row 1 – Channel on/off
Clicking each box turns all channels or individual channels on and off. When a
channel has a sensor that is connected but turned off, the entire column will be
grayed out. When a channel is on, editable fields will become a light color. The
channel on and off status only affects the channel window (it does not affect the
Logging window, except for removing that particular channel as selectable for
logging).
All Channels
Checking or unchecking the box above “All Channels” turns on and off every
channel where a sensor is connected. If there is a mixture of sensors that are on
and off, the box will be grayed out. In this grayed out state, clicking the box will
turn on the channels that were previously off. Clicking the box again will turn
off all channels.
3-10
Page 18

Software
Individual Channels
If a sensor is connected, checking or unchecking the box above each channel
turns on and off that specific channel. When a sensor is connected, the channel
will automatically turn on. When a sensor is disconnected, the channel will turn
off automatically.
2) Row 2 – Channel number
Indicates the channel number for each column.
3) Row 3 – Serial number
Displays sensor serial numbers for sensors that are connected whether the
channel is off or on.
4) Row 4 – Channel Name
The user can assign a descriptive name for the channel in this box, up to 20
characters and spaces. The default is blank.
5) Row 5 – Engineering Units
Clicking on the drop down box allows the user to choose from other engineering
units that will be applied to Channels and Logging windows. The user can select
from a standard list of engineering units (the default is the units assigned to the
sensor), or “CUSTOM”, where user can type a custom label in row 6, and specify
scalar and offset in rows 7-8. Scalar and Offset are applied in that order. Only
standard engineering units within the same type of sensor are selectable. For
example, PSI G (gage) cannot be changed to mbar A (absolute).
6) Row 6 – Custom Label
When “Custom” units are specified in Row 5, this box will be editable, and the
user can type text up to 4 Characters/Spaces. This text will appear in the
channels window next to the digital readout, and next to the recalculated sensor
range. The default is blank.
7) Row 7-8 – Scalar and Offset
When “Custom” units are selected in row 6, the numbers entered in the scalar
and offset fields will modify the output of the sensors by applying a unit
conversion, and the result is applied to channel and logging windows. The order
of operations is: Output = (scalar * sensor output) + offset. The scalar and offset
can be positive or negative. The maximum value that can be entered is 11
significant figures. The default is blank, i.e. no effect (equates to a one for scalar
and a zero for offset). The user alarms are affected by the scalar and offset values
as indicated in “ 13) Row 17-21 and 22-26 – User Alarms”.
8) Row 9-10 – Custom Range
When “Custom” units are selected in row 6, and a scalar and/or offset value is
entered in Rows 7-8, the new sensor min/max range will be displayed, which is
the sensor’s native range, modified by the scalar and offset. The custom range
boxes are grayed out if “Custom” is not selected in row 5, and will display the
range of the native units of the sensor.
9) Row 11 – Sample Rate
The sample rate specifies the number of samples per second that the data will be
acquired from the sensor. The sample rate is selectable from the drop down box
with the following choices: {5, 10, 20, 40, 80, 160, 320, 640, 1000} samples per
second (5 to 1kHz). The actual sample rate can vary by the sensor’s sample rate
tolerance.
3-11
Page 19
Software
3
10) Row 12 – Display Update Rate
The display update rate, in Hz, is user defined, and specifies the update rate for
the digital readout in the Channels window. Values between one and ten are
selectable from a drop down box. The default is 3Hz.
11) Row 13 – Maximum Decimal Places
Sets the maximum number of decimal places that are shown on the sensor
readings in the channel window.
12) Row 14-16 – Filters
The filter values specify the amount of filtering that is applied to the data in the
corresponding channel. The filters affect the data that is displayed in both the
Channels and the Logging windows. Filters can be used in combination. The
filter application order is: 1) Moving Average, 2) IIR, 3) and Boxcar, where the
output of each filter is the input to the next filter. Note that if advanced filtering
is desired, all of these filters can be disabled (OFF), the data logged, and post
processing can be done on the logged data. Note that increased filter values
decrease the response time of the indicated output. The filters must be set
according to the desired sensitivity.
a) Row 14 - Moving Average Filter
The moving average filter is a simple averaging filter that adds the number of
samples specified by the value set in this box, and divides by the value set in
this box. Before each calculation, the oldest sample is subtracted, the new
sample is added, and a new calculation is done. This filter is effective at
filtering noisy signals, but not impulse signals. Selectable values are: MA OFF
(disabled), and two through 63.
b) Row 15 – Boxcar Filter
The boxcar filter takes a number of readings, averages them, then outputs one
reading for the entire group. This is the only filter that modifies the sample
rate of the sensor. The net sample rate is the value entered in row 11 divided
by row 15. Selectable values are: Boxcar OFF (disabled), 2, 4, 8, and 16.
c) Row 16 – Infinite Impulse Response filter
Calculation: Output previous filtered reading + ((new raw reading – previous
raw reading)/n where n = the number entered in the Row 16 box. The “n”
value effectively is the weighting that the new reading has on the output of
the filter. Selectable values are: IIR OFF (disabled), two through 63.
13) Row 17-21 and 22-26 – User Alarms
There are two independent Alarms that can be enabled. The alarms impact the
channel window only, and are user configurable according to the settings
described below. When an alarm is annunciating, the window will flash yellow
or red (depending on the entries in rows 18/23), along with flashing “High” or
“Low” text (matching the setting in row 18/23). The user alarm thresholds
default to the sensor’s native range.
a) Row 17/ 22 – User Alarm on/ off.
Enables/disables alarm 1 and 2. Settings are retained after turning off an
alarm (alarm rows are grayed out, but still show values, and can still be
changed), and remain after the alarm is turned on. Alarms are not
annunciated in the Channels window when a sensor’s channel is turned off.
3-12
Page 20
3
Software
b) Row 18/23 – User Alarm High/Low
Configures alarm as low or high alarm (low meaning alarm triggers as value
passes from high to low through the alarm setting, high meaning that the
alarm triggers as value passes from low to high through the alarm setting).
Select with drop-down box. If both alarms are set to low or to high, a two
stage alarm can be configured. When passing the first threshold, the flashing
window will be yellow, and passing the second threshold will produce a red
flashing window.
c) Row 19/24 – User Alarm Threshold Value
The user-defined value, which triggers the user alarm when the sensor output
is above or below the value (determined by Row 18/23). This value is
automatically recalculated by the software when the engineering units are
changed (either to standard or custom). Valid values are up to the Overload
Alarm setting (usually 10% above/below the upper/lower range of the
sensor).
d) Row 20/25 – Latching
User can enable or disable latching for each user alarm. If latching is enabled,
the user alarm continues to annunciate when the sensor output returns from
(user) alarm triggered to a non-triggered value.
e) Row 21/ 26 – Deadband
The Deadband provides hysteresis to prevent flickering alarm conditions
when the sensor output is near the alarm limit. The Deadband region is user
selectable, and is an absolute value. If an alarm is configured as a high alarm,
the alarm will be triggered as it increases above the value specified by Row
19/24, but annunciation of the alarm will not stop until the sensor output
drops below the alarm value minus the Deadband value. Likewise, for an user
alarm configured as a low alarm, the user alarm will be triggered as it falls
below the value specified by Row 19/24, but annunciation of the user alarm
will not stop until the senor output rises above the user alarm value plus the
Deadband value. If latching is selected (Row 20/25), the Deadband will be
grayed out and not editable. The Deadband value must be positive, and
cannot be greater than the sensor range. Using the diagram below as a
graphical example, the high user alarm threshold is 50 PSI, and the Deadband
is 10PSI. If the sensor output triggers the alarm at 50PSI, the user alarm will
continue to annunciate until the sensor drops below 40PSI.
3-13
Figure 3-18. Deadband Example
Page 21
Software
NOTE:
3
Changes to Scalar and Offset will affect the user alarms in
the following manner:
1) If the scalar value is inverted: High/Low user alarm inverts
(High becomes Low, Low becomes High).
2) If the scalar value is other than 1: The user Alarm values
are multiplied by the scalar value.
3) If the offset value is other than 0: The user alarm values are
offset by the offset value.
14) Row 27 – Max/Min Hold
User selectable hold display mode (affects Channels window only). Min/Max
hold, and normal (no hold) are the choices in the drop down box. Each channel
has a separate Min/Max value, and recording begins when the channel is turned
on, and flushed when the channel is turned off or disconnected. Min and Max
are constantly being stored regardless of the value of this selection box.
15) Row 28 – Tare
Tare is an offset applied to the sensor output, and displayed in the Channels
window, and in the logged data. The offset is calculated and subtracted from the
sensor output when the tare button is pressed, resulting in a zero sensor reading
at the instant when the tare button is pressed. A check in the box means that the
Tare is applied, and no check means Tare is not applied. Each time the tare
button is unchecked and checked, a new tare value is calculated and applied.
The Tare affects values stored in the channels window, and also the logged data.
It is advisable to not use the Tare function during logging. The tare value is
stored in temporary memory, and is erased when power is removed from the
unit.
16) Row 29 – Unit Type
The Unit type is a Factory specified code, and is not changeable by the user.
17) Row 30 – Sensor Firmware Version
18) Row 31 – Range
The range of the sensor in the original engineering units before any conversions
are applied.
3.4.3 Channels Window
The Channels Window shown below is the default window that is displayed
when you run the program. This window provides a real-time digital reading of
sensor output when used with the PX409-USBH family.

Channels Window Special Cases
Figure 3-21. User Alarm Annunciation in Channels Window
1) User Alarm Annunciation (case where only one user alarm is set, or both user
alarms are set and are opposite high/low values): When a sensor output has
exceeded/receded above/below the user alarm threshold as specified in the
Channel Config window, the channel window will change to a flashing red color,
with “High” or “Low” being flashed (depending on if a High or Low Threshold
has been exceeded). If the sensor output returns to a value outside the alarm
threshold, AND latching is off, the alarm will stop annunciating. If the sensor
output returns to a value outside the alarm threshold, AND latching is on, an
Alarm Reset button will appear, and the alarm will continue to annunciate until
this button is pressed.
2) User Alarm Annunciation (case where both user alarms are set and are the
same type, high/low): When a sensor output has exceeded or receded
above/below the first user alarm threshold as specified in the Channel Config
window, the channel window will change to a flashing yellow color, with
“High” or “Low” being flashed (depending on if a High or Low Threshold has
been exceeded). If the sensor value continues into the second user alarm
threshold value, the window will change to a red flashing color. If the sensor
value changes back to between the two thresholds, (and latching is off), the
flashing window color will change back to yellow. If the sensor value changes
below/above the first low/high threshold (and latching is off), then the user
alarm will stop annunciating. If latching is ON, the highest user alarm that was
previously tripped will remain flashing until the user “Alarm Reset” button is
pressed.
3.4.4 Miscellaneous
1) Overload alarm. Each sensor is factory configured with an overload alarm.
The value of the overload alarm varies between each sensor type/range, but it is
above and below the upper and lower range values of the sensor. When the
overload alarm is tripped, the box will change to a solid red, and the sensor
reading will change to the word “OVERLOAD” while the overload is still
applied to the sensor. When the sensor output has returned outside the overload
alarm threshold, the sensor reading will be displayed again, but the window will
remain red, and “OVERLOADED” will appear in the lower area of the readout
window, and will remain until the sensor is disconnected, or the program is
closed.

Figure 3-22. Overload Alarm Annunciation in Channels Window
If the sensor output enters the Overload range again, “OVERLOAD” and
“OVERLOADED” text will be displayed simultaneously. When the sensor
output returns outside the Overload range, “OVERLOAD” will disappear, but
“OVERLOADED” will remain.

3.4.5 Logging Window
The Logging window enables logging of the data for a maximum of 12
connected sensors. The sensors can be any combination of samples per second
and Engineering Units. The parameters of the data collected by the logging
function are adjusted by the Channel Config window.

Description of Logging Window Elements
1) Logging file setup
Specify the file location for the log file to be stored. Press the Browse button to
open the Choose Base Logfile Name box, browse for the file location, and enter a
name for the .csv file. Choose Comma or Tab delimiting. If the logging file
already exists, a prompt will appear: “The file {path} already exists, would you
like to replace it?” Clicking “Yes” will replace the file, clicking “No” will return
to the “Choose Base Logfile Name” box. Note that individual .csv files will be
created for each channel, with a suffix “-channelxx“ added to the base file name,
where “xx” is the channel number.

2) Logging start button
Pressing the “Start” button will start the logging of the selected channels to the
selected file location. The “Start” button will then be grayed out and
unselectable, and the “Stop” button will become active. Changes are permitted
to all parameters in the Channel Config window; However, for most
configurable items, a pop up box will warn the user that changes to that item
require that the logging operation is stopped. Pressing “Yes” will stop logging
and apply the parameter change, pressing “No” will continue logging and
disregard the parameter change.
3) Logging stop button
Halts the current logging operation
4) Logging channel selection
Select which channels are available to be logged. Only channels that are
connected and turned on will be selectable. No changes are allowed while
logging is taking place.

Section 4 – Troubleshooting
1) Sensor is not recognized by the software program
Checkpoints:
a) Disconnect the sensor from the USB port of the computer, wait 5 seconds, then
connect the sensor.
b) Verify that the latest FTDI driver is installed on the computer. If not,
disconnect all sensors, and update to the latest driver from FTDI
(http://www.ftdichip.com/Drivers/D2XX.htm). It is recommended to choose
the executable driver under the Comments field for best results.
2) The Data is noisy
a) Reduce the sample time. Faster sample rates have more inherent noise.
b) Reduce the number of decimal places shown if the current resolution is not
needed.
c) Filter the data with the Moving Average, IIR, and/or the boxcar filters. Note
that this decreases response time of the sensors to fast moving inputs to the
sensor.
