DT80 Concepts
What is the DT80?
The dataTaker DT80 range of data acquisition and logging instruments are tools to measure and record a wide variety of
quantities and values in the real world.
The web based dEX graphical user interface makes it quick and easy to define basic measurement tasks. Logged data
can then be easily extracted via a USB "memory stick", or downloaded using the web interface into files ready for import
into spreadsheets and data analysis tools.
The DT80 range of loggers also include a powerful programming language which allows complex systems to be
developed and monitored.
Extensive sensor support and communications options, and a rugged and low-power design, make the DT80 a very
flexible data logger.
The DT80 Product Family
Models
The DT80 product family includes the following models:
The DT80 is a full-featured data logger,
The DT82E is a low cost, low power logger designed for environmental applications.
UM-0085-B11E DT80 Range User Manual Page 15
RGJKLJW
The DT82I is designed for industrial applications.
The DT85 is an expanded and enhanced version of the DT80.
The DT80L and DT85L are low power variants of the DT80 and DT85.
The DT80W and DT85W are WiFi variant of the DT80 and DT85.
The DT80G and DT85G GeoLoggers are designed for Geotechnical applications
The DT80GW and DT85GW are WiFi variant of the DT80G and DT85G.
The DT80GL and DT85GL are low power variants of the DT80G and DT85G.
The DT82EM3, DT80LM3, DT85LM3 and DT85GLM3 contain an inbuilt GSM/EDGE/WCDMA cellular modem.
The DT82EM2, DT80LM2, DT85LM2 and DT85GLM2 contain an inbuilt GSM/EDGE cellular modem.
The CEM20 (Channel Expansion Module) is a 20-channel analog multiplexer which can be used to expand the
number of analog input channels on a DT80 or DT85.
All of these models operate in a similar way; the differences are mainly to do with the number of input channels and other
hardware features. Table 1 (P16) and
Table 2 (P17) lists the main differences between each model.
Series 1, 2, 3 and 4
In January 2008, the original DT80, DT81 and DT85 models were superseded by enhanced Series 2 models. These
offered an all-new web based interface (dEX), additional power outputs, and more flexible analog input switching.
Series 3 models were introduced from October 2010. These supersede Series 2 and include enhanced resistance
measurement options and an isolated switched 5V power output.
Series 4 were launched from February 2017 and include increased voltage and resistance measurement ranges, flexible
12/ 5V power outputs and integrating with DAC converter to produce voltage/ current outputs as well as WiFi connectivity
support.
Along with DT80 Series 4 launch the new CEM20 Series 2 has also been released. In CEM20 Series 2 all mechanical
relays has been replaced by opto-relays. As result all audible noise from the mechanical relay switching was eliminated.
Series 2, 3 and 4 units are clearly labelled as such on the front panel. When a logger model number is displayed, the
series is shown as a suffix, e.g. "DT85L-3" is a Series 3 DT85L.
GeoLoggers
The DT80G/GL and DT85G/GL "GeoLoggers" are equivalent to the DT80 and DT85, but also include direct support for
vibrating wire strain gauges, which are widely used in geotechnical applications; see Strain Gauges – Vibrating Wire
(P320). Throughout this manual, references to the DT80 and DT85 also refer to the DT80G and DT85G respectively,
unless otherwise noted.
Low Power Models
Most DT80 models include an internal 6V lead acid battery. However the low power "L" and "E" models do not include
an internal battery and are instead optimised for operation with an external battery (often solar charged). Throughout this
manual, references to the DT80 and DT85 also refer to the DT80L and DT85L respectively, unless otherwise noted.
Modem Models
The "M" models (DT82EM, DT80LM, DT85LM, DT85GLM) include an integrated cellular modem, which provides a
convenient wireless solution for control of the DT80 and data retrieval. The "M3" models support 2G and 3G networks
(GSM/ GPRS/ EDGE/ WCDMA), while the "M2" models support 2G only (GSM/ GPRS/ EDGE). Apart from this
difference, the M2 and M3 variants operate identically.
WiFi Models
The "W" models (DT80W, DT80GW, DT85W, DT85GW) include an integrated WiFi interface, which provides a
convenient wireless solution for control of the DT80 and data retrieval. See WiFi Communications (P238).
Channel Expansion Module
The CEM20 is an analog multiplexer designed to work with a DT80 or DT85 Series 2 logger and later revisions. It
provides an easy way to expand the number of input channels. Up to 16 CEM20 modules can be connected to a DT85,
giving a total of 320 input channels. See The CEM20 (P370).
Note: In this manual, the term DT80 (italics) is used to refer to all products (DT80, DT81, DT82 and DT85; Series 1, 2, 3 and 4). If a
feature or behaviour is specific to a particular model, this will be made clear in the text.

DT80-Friendly Software
Programming and Configuration
There are three main ways to set up and program the DT80.
dEX is a web based application for programming and monitoring DT80 Series 2/ 3/ 4 data loggers. dEX is built
into the logger (no installation required) and runs in your web browser. It provides a totally graphical interface,
which means that knowledge of the dataTaker programming language is not required. Channels and schedules
are defined simply by clicking on icons and making selections from menus and dialog boxes; dEX will then
generate the required DT80 program and load it onto the logger.
Alternatively, commands entered interactively and then sent to the DT80 via one of its comms ports or a TCP/IP
network. This allows full access to the DT80's capabilities. DeTransfer, or the enhanced web interface's
command window, are the best tools for the job here. They both have separate send and receive windows, a
macro facility, and many other useful features. A standard terminal program (e.g. HyperTerminal) can also be
used.
Finally, you can develop a DT80 program off-line (e.g. using a text editor), then transfer it to the DT80 using a
USB memory device or send it as a file using DeTransfer.
Viewing Data and Status
Once the DT80 has been set up, there are a number of options for retrieving data and monitoring status:
The DT80's inbuilt web interface (dEX) provides a convenient way to access current data values and status
information from any web browser. dEX is available on Series 2, 3 and 4 loggers.
A simple HTML-based web interface is also provided on all loggers. This can be customized if required to
provide an application-specific user interface. This interface is designed to operate efficiently on slow
communications networks or on portable devices with a small display screen.
DeTransfer can be used to view real-time and logged data in text format.
dataTaker Instrument driver for LabVIEW™ is a set of drivers and documentation which allows dataTaker
data loggers to be incorporated in a LabVIEW environment. LabVIEW is National Instruments' industry-leading
graphical software development environment for measurement and automation applications.
All software is provided on the CD supplied with your DT80, and updates are available from the dataTaker website,
www.datataker.com (Support/ Downloads section).
About This Manual
This manual is intended for all users of the DT80. It describes:
How to connect sensors and other devices to the DT80's input and output channels.
How to program the DT80 to collect and return data as required.
How to manage the data that the DT80 collects.
The main focus of this manual will be on directly programming the DT80 using its command language. However, most of
the concepts discussed here also apply when building programs using tools such as dEX.
A Tour of the DT80's Interfaces
The DT80's interfaces with the outside world are grouped into three main areas: user interface (top), sensor interface
(front) and communications interface (side). See also Inputs and Outputs (P274).
User Interface
On the top panel of the DT80 you will find controls which allow the user to interact with the unit during operation – without
requiring a host computer:
A 2-line LCD display shows status messages, measured values, and a menu of pre-defined functions (not
DT81)
Six keypad buttons allow the user to navigate between the various displayed options (not DT81)
Four status LEDs are provided – the blue Sample LED flashes each time a measurement is taken, the green
Disk LED indicates internal flash disk activity, and the red Attn LED indicates various warning conditions, and
the green Power LED flashes at 3 second intervals while the logger is powered and not in low "sleep" mode.
The duty cycle of the flash indicates whether the logger is externally powered (long flashes) or running from its
internal battery (short flashes).
Note: Power LED is not present on DT80 Series 1.
A USB socket allows connection of a USB memory device, which provides a convenient way to retrieve data
from the DT80 (or load a program onto it).

Sensor Interface
On the sloping front panel of the DT80 there are two rows of terminal blocks – digital channels on the left, analog
channels on the right. The green terminal blocks can be quickly unplugged from the DT80 without unscrewing the sensor
cabling. This interface includes:
8 digital input/ output/ counter channels (1D–8D), 4 of which are SDI-12 compatible (DT82I: 4 channels; DT81/
82E: 4 channels, one of which is SDI-12 compatible)
an input to wake the DT80 from low power "sleep" mode (WK)
4 high speed counter inputs (7 on DT85/ 85L Series 3) (1C–4C)
2 phase encoder inputs, shared with the counter inputs connected) (1PE–2PE) (one phase encoder input on
DT81, none on DT82E, 3 on DT85/ 85L Series 3)
a pair of voltage free relay contact outputs (RELAY A and B)
a general purpose switched 12V 150mA power output (12V) (DT80/ 81/ 82E and DT85 Series 2/3 only)
a general purpose switched 12V/5V 300mA power output (12V/5V) (DT80/ 82E, DT85 Series 4 only)
a general purpose current limited (300mA) power output (PWR OUT), which is derived from the external power
input (DT85 only)
an isolated switched 5V power output (5V SW) (Series 3 only)
an isolated programmable 16-bit voltage and current output (V/I DAC) (Series 4 only)
digital / power ground terminals (DGND)
an RS232/422/485 compatible serial port (Tx, Rx, RTS and CTS) (not present on DT81/ 82E)
a number of analog input channels (5 channels for DT80, 1 channel for DT81, 16 channels for DT85)
an external excitation input (EXT *)
isolated analog ground terminals (AGND on DT80/81, EXT# on DT80 Series 2 and DT85)
Note: early production DT80 models only had 4 analog inputs
Communications/ Power Interface
On the left side panel you have a variety of connectivity options:
10-Base-T Ethernet for connection to a host computer or local area network
USB for high speed connection to a host computer (not present on DT82)
RS232 for connection to host computer or modem (not present on DT8xM)
two alternative DC power connectors – a standard plug-pack socket (DC jack) and a 4-pin terminal block (2-pin
for DT82E/ 80L/ 85L)
For more details, see Communications (P180)
Wireless Modem Interface (DT8xM only)
On the right side panel are the integrated modem interface:
SIM card slot (subscriber identity module)
Red status LED
Coaxial screw connector for optional "receive diversity" antenna (DT8xM3 only)
Coaxial screw connector for main antenna.
A threaded earth point is also available on both left and right side panels. See Grounding (P281).
WiFi Interface (DT8xW only)
On the right side panel are the integrated WiFi interface:
Coaxial screw connector for main antenna.
A threaded earth point is also available on both left and right side panels. See Grounding (P281).
Getting Started
Power
Powering the DT80 (P281) discusses the ways to provide power to the DT80. The simplest option is to plug in the
supplied AC adaptor.
All DT80 models except the DT82E include an internal 6V lead-acid battery which can power the logger if the main
external supply is interrupted.
Important: The DT80 is shipped with its main internal battery disconnected. We recommend the battery is connected as soon as
practical so that it can charge from the mains adaptor or other external power source. This is achieved by simply plugging the green
power connector, see Powering the DT80 (P281).

Switch On!
When power is connected, you should observe:
the LCD backlight switches on (DT80/ 85), and the green Power LED starts flashing
a brief clicking sound as the unit performs an initial self-calibration
DT80 restarted / Power loss is displayed on the LCD
the front panel LEDs flash a few times then the red Attn LED continues to flash.
The DT80 is warning you that its power has been interrupted. Press any of the front panel keys to clear this indication.
The Attn LED should stop flashing and the display should now read: DT80 V9.20 / No current job. This indicates
that:
the version of DT80 firmware in use is "9.20" (this number may vary), and
no user program (or "job") has been loaded
The DT80 is now idle and waiting for instructions.
Connecting to a Host Computer
In order to program the DT80, it is generally necessary to connect it to a "host" computer. The easiest option here is to
use the supplied USB cable, or, for the DT82E/82I, the supplied Ethernet cable. Other options are to use a "null-modem"
(cross-over) RS232 cable, or to connect the logger to an Ethernet network. See Communications (P180) for more details
of the different communications options.
Very briefly, connecting the DT80 via USB involves the following steps:
1. Install the supplied DTUsb driver software. This allows you to access to DT80's network services via a USB
connection.
2. Connect the USB cable between the DT80 and the PC.
3. The Windows "New Hardware Found" wizard will then run automatically (if required) to complete the installation
of the necessary drivers.
4. Your default web browser will then be launched automatically and the dEX home page will be displayed.
To connect to the DT80 using Ethernet:
1. Connect the Ethernet cable between the DT80 and the PC, or between the DT80 and a socket on your
computer's local area network.
2. Use the DT80 keypad to scroll down to the "Ethernet" screen. Check that a valid IP address is displayed, e.g.
169.254.3.202
3. Launch your web browser and type the logger's IP address into the address bar. The dEX home page should
be displayed.
The above is only a brief overview. See USB Port (P185) for detailed, step by step instructions.
As an alternative to the dEX web-based interface, you can also install the supplied DeTransfer software, which can be
used to send the text-based commands described in this manual to the logger. DeTransfer can operate over a direct
RS232/ USB connection or a network connection, and will work with any logger model.
The remainder of this manual will assume you have successfully established a connection between the host PC and the
DT80.
Sending Commands
The DT80 is programmed by sending it textual commands. These commands may be either:
Manually entered (using DeTransfer, or the Command screen in dEX), or
Generated by the dEX configuration builder, based on details entered using its graphical user interface controls.
Commands are executed by the DT80 only after it receives a carriage-return character ().
Commands are not case-sensitive; that is, they may be entered using either uppercase or lowercase characters.
In this manual all commands are shown in UPPERCASE. Responses from the DT80 are shown like this.
After receiving a command, the DT80 will normally echo the command, after converting it to uppercase. After a command
has been processed, the DT80 will normally indicate that it is ready for the next one by transmitting a prompt string,
such as:
DT80>
Note: the DT80 does not echo each character as it is received.
Command echo and the prompt string can be turned off if required using the /e switch command, see Switches (P258).
The maximum length of a command is 1023 characters.
