Introduction 1
1.4 Overview
The OM-DAQXL is an 8 or 16 analog input portable data logger with a color
7” resistive touch screen display. It has user programmable inputs that can be
configured for several different types of sensors including temperature sensors
(thermocouple, RTD, thermistor), strain gage, process inputs (voltage and
current) and digital pulse inputs. All configurable options (including individual
channel input type and range) are software programmable. The device is
powered by a 7.2V, 4.8 Ah Li-ion battery. In addition an external 12V, 5A AC
adapter can be used to power the device for extended periods.
The compact, portable packaging ensures ease of use in a variety of applications.
Devices can be wall mounted using the provided keyhole mount or easily
operated on a bench.
The device has four operating modes:
1. Free Running – In this mode the device measures and displays configured
analog / digital inputs. No Logging is performed. No Trigger conditions are
set.
2. Armed Mode – In this mode the device measures and displays configured
analog / digital inputs. A Start Trigger condition is set. No Logging is
performed until the Start trigger condition is met.
3. Logging Mode – In this mode the device measures and displays configured
analog / digital inputs. The device is also logging data from the input channels
to the designated memory location, either the SD card or the USB drive or the
internal memory.
4. Data Review Mode – In this mode users can review previously recorded data
in a graphical view. Zoom in and out. Scroll through the data back and forth in
time. Review recorded data from any 4 channels on one screen.
1.4.1 Operating Environment
The OM-DAQXL has been designed to meet its stated specifications when
operating within the ambient conditions outlined below.
Temperature: 0 to 50 deg C (32 to 122 deg F)
Humidity: 0 to 95% RH non-condensing
In addition to restricting operation of the data logger to the given temperature
and humidity ranges, a warmup period of 30 minutes is recommended to ensure
best accuracy of measurements.

2.3 Part Names and Functions
The figures in this section show the different parts of the data logger and provide
a brief description of their functions.
2.3.1 Front
The front of the data logger is comprised of 3 user interface elements. These are
the 7” touch screen LCD, three status LEDs and the home button. The touch
screen display is used to display all measured data, settings & configuration
menus and status information. The three status LEDs provide visible indications
of power & battery charging status, data logging status, and alarm status.
Depending on the current status the color of the LEDs will vary. For LED color
indications, see Section 2.10. The Home button is the single hardware button for
the user interface. It provides a quick and easy way to return to the Home screen
from any other screen with one button press.

a 30 degree angle when sitting on a hard surface and snaps into place when not
in use. The kickstand has 2 keyhole slots allowing it to act as a wall mounting
bracket. See Section 2.5 for information on how to wall mount the device. The
battery compartment door is also located on the back of the device. See Section
2.11 for information on how to replace the battery.

2.4 Removing & Installing Rubber Boot
The data logger ships with an impact resistant rubber boot pre-installed.
OMEGA recommends leaving the protective rubber boot installed, but it can be
removed for convenience. When removing the rubber boot be sure to do so with
a support surface not more than 1 foot beneath the device to protect in the case of
an accidental drop.
To remove the device from the rubber boot first power off the device and
disconnect all external connections including power, analog & digital inputs,
and communication interfaces. Next while holding the device with one hand
gripping the top of the device, use the other hand to pry one of the bottom
corners of the rubber boot outward and downward until the corner of the device
pops free from the boot. Repeat for the other bottom corner of the device. With
both of the bottom corners free of the boot, continue to tilt the bottom of device
upward and pull it outward until it is free from the boot. Installation is the
reverse of removal.
2.5 Wall Mounting
The data logger features a built in kick stand with keyhole screw slots that fit #6
(M3.5 metric) sized screws for wall mounting.

2.6 Sensor Connections
This section shows how to connect sensors to your analog input terminals.
There are 8 or 16 analog input channels (depending on the model) each having
one positive terminal and one negative terminal clearly shown on the input
label. Depending on the type of sensor being connected 2 input channels may
be required. Input tables and figures are shown for each type of input. Bridged
based sensors (strain gages, load cells and mV output pressure transducers)
require excitation voltage which is provided on channels 1 and 2, 3 and 4,
9 and 10, 11 and 12 only. See tables 2-3 and 2-4 for wiring information.
2.6.1 Two wire sensors
For two wire sensors any open channel can be configured to read the sensor.
2.6.1.1 Thermocouples
For thermocouple sensors the negative lead is always colored red
(USA and Canada) or white (IEC 584-3).

2.6.2.2 Three-Wire RTD Wiring
For 3-wire RTD sensors the second common lead must be connected to the
negative terminal of the next consecutive even channel.
2.6.2.3 Four-Wire RTD Wiring
For 4-wire RTD sensors the data logger performs a Kelvin resistance
measurement using 1 channel to supply excitation voltage and the next channel
to sense the voltage across the RTD.

2.6.2.4 Thermistor Wiring
For thermistor sensors connection, 2 channels are required as shown in Figure 2-16.
2.6.2.5 Bridge Sensor Wiring
For bridge based sensors excitation voltage is supplied on channels 1, 3, 9 and
11. The next consecutive even channels must be used to measure the sensor
output. Bridge based sensor inputs are only available on channels 1-2, 3-4, 9-10
and 11-12.

2.7 Digital I/O Connections
The included 6’ digital I/O cable with stripped leads and mini-DIN connector
makes connecting digital I/O to the data logger quick and simple. Table 2-5
shows the cable pinout and figure 2-18 shows the corresponding pins on the data
logger connector.

2.8 Alarm, Excitation & Trigger
The eight position terminal block on the left side of the device has terminal positions for four alarm
outputs, an isolated 24 VDC excitation supply and an external trigger input. Connections are made
easy through the included pluggable terminal block. Follow the terminal indications on the label
and connect to the appropriate position
2.9 USB Device & Host ports
The data logger features a USB device port for communication with a PC using
the supplied USB cable.
There is also a USB host port which allows external USB memory to be used for
data storage. USB Memory up to 64GB in size can be used with the data logger.
The USB host can also be used to connect a USB mouse. For -EW models, the
USB WiFi dongle accessory plugs into the USB host for WiFi capabilities.
