Introduction
What is “Data Collector TR-57DCi”?
Overview
The TR-57DCi is a device designed to collect recorded data from data
logger(s)alreadyplacedintheeld.Itisalsopossibletoview
collected data and start recording on data loggers in areas where a
computer is not available.
Compatible Data Loggers
TR-71Ui / 72Ui / 74Ui / 76Ui / 77Ui, TR-71U / 72U / 73U, TR-71S / 72S, TR-71 /
72, TR-51i / 52i / 55i, TR-51S / 52S, TR-51A / 52 / 51, VR-71, RTR-51A / 52A /
53A*, RVR-52A*, RTR-51 / 52 / 52Pt / 53*, RVR-52*
* The TR-57DCi is not equipped with a wireless communication function.
Basic Functions
Easy Collection of a Variety of Data
The TR-57DCi can collect data from a wide variety of compatible data loggers.
Storage Capacity of 256,000 readings
One TR-57DCi has the capacity to store 16 units of TR-71U at full storage
capacity (8,000 readings x 2ch).When downloading units at non-full storage
capacity, it can store and manage up to 250 downloading sessions.
Collecting Recorded Data via Infrared Communication
The TR-57DCi can also use infrared communication to collect recorded data
from any of the TR-7Ui and TR-5i Series Data Loggers. Using infrared
communication releases the user from the burden of physically gathering
the loggers to collect data.
Graph Display on High Quality LCD
Collected data can be viewed immediately on the spot without the need for
a computer. The handy Operation Dial and buttons on the face of the Unit
make it possible to move the cursor as well as zoom in and out, thereby
making the checking of data a snap.
Handy Operation Dial for a Variety of Operations
Moving the Operation Dial up and down displays the various menu
selections which can be easily selected by pressing in on the dial.
Make Recording Condition Settings
From the TR-57DCi, it is possible to make settings, such as for “Recording
Start Date and Time”, “Recording Interval”, and “Recording Mode” for all
compatible data loggers except the VR-71.
Battery Life Warning Display
When the battery power becomes low, a battery life warning mark will
appear in the Unit's LCD display.
About 100 Days of Battery Life with One Hour Daily Use
The expected battery life for two AAA alkaline batteries (LR03) is as follows:
used thirty minutes daily it should be about 160 days, used one hour daily it
should be about 100 days, used two hours daily it should be about 50 days.
In addition to AAA alkaline batteries, AAA Ni-Cd or AAA Ni-MH batteries
(1.2V) may also be used.
* Battery life varies depending upon the type of battery, the measuring
environment, the frequency of communication, and the ambient temperature in
whichitisused.SpecicationsandexplanationsusedinthisUser’sManualare
based on operations carried out with a new battery and are in no way a
guarantee of your actual battery life.
Auto Power OFF Function
IftheUnitisnotusedforaboutthreeminutes,itwillautomaticallyturno
to save battery power.
Backlight Function
The LCD Backlight allows the display to be easily read even in the dark. You
can make changes in the Backlight ON/OFF by going to the [Main] Menu
- [Set Functions] - [Set Backlight].
* IftheUnitisnotusedformorethanveseconds,theLCDBacklightwill
automaticallyturnotosavebatterypower.Onceoperationisre-started,itwill
automatically turn back ON.
Firmware Update Function
ThermwarecanbeeasilyupdatedbyconnectingthetargetTR-57DCiwitha
USB communication cable to the computer. As newly compatible devices are
released,rmwareupdateswillbeperiodicallyreleasedtosupportthese
changes.Formoreabouthowtoupdatermwareandthelatestupdate

Downloading Recorded Data
Use this to download recorded data from Data Loggers to the
TR-57DCi.
Downloading via Optical and Cable Communication
1.
Connect the Data Logger to the TR-57DCi. (See p.23)
2.
In the Main Menu, open [ Gather Data] to start downloading.
When using data loggers for which the period of data to be downloaded
is user-selectable, the settings window will appear as follows.
After the selection is made, adjust the arrow to [Execute] and press the
Operation Dial to start downloading recorded data.
* If you wish to stop downloading, press the dial again.
3.
A graph will appear showing the downloaded data.
Downloading via Infrared Communication
1.
In the Main Menu, open [ Gather Data] or press the <
Ir>button on the TR-57DCi Unit.
2.
Under [Sel.Logger], select the Data Logger Series from which you
wish to download data.
For the TR-7Ui Series, just select “TR-7i”. For the TR-5i Series, after select-
ing “TR-5i”, then select the period of data to be downloaded.
* When using the < Ir>button to download data, this window will not appear and
communication will be carried out according to the same settings as the
previous session.
3.
After adjusting the arrow to [Execute] and pressing the Operation
Dial, place the infrared port of TR-57DCi and data logger face-to-
face. (See p.23)

If Downloading Recorded Data Fails
Check the following:
Is there enough memory left in the TR-57DCi for the data?
If there is not enough memory remaining, the message [Memory Full] will
appear and downloading will stop. Please save recorded data from the
TR-57DCi to your PC and delete unnecessary data from the TR-57DCi to
make space for downloading new data from the Data Logger.
- See p.41 for details about how to check for remaining memory capacity.
- See p.44 for details about deleting data.
Has Infrared Communication been set to “Forbid”?
If a target TR-7Ui or TR-5i Series Logger has not been set to “Permit"
Infrared Communication, it will be impossible to download recorded data
via Infrared Communication. Using the software “T&D Recorder for
Windows” or “Illuminance UV Recorder for Windows”, make the necessary
settings to permit Infrared Communication, and try downloading again.
- The application for the TR-76Ui does not have a setting to enable or disable
infrared communication; Infrared communication is always enabled.
- For details about Infrared Communication Settings, see the Data Logger User’s
Manual or the [Help] Menu in the supplied software.

1. Displayed Channel
If there are multiple channels of recorded data, you can change the channel
on display by holding in the Operation Dial (for about one second).
2. Cursor
By moving the Operation Dial, you can scroll the cursor left and right to
view the recording date and time and measurement for that point where
the cursor is positioned.
3. Recording Interval and Mode
The “Recording Interval” and “Recording Mode” for the displayed data are shown
here.
S: Seconds, M: Minutes, : One Time, : Endless
4. Measurement at Cursor Position
The corresponding measurement value is displayed for the date and time
where the cursor is positioned.
[°C/°F]: Temperature, [%RH]: Humidity, [hPa]: Barometric Pressure,
[lx]: Illuminance, [mW/cm2]: UV Light, [V]: Voltage, [mA]: 4-20mA,
[Pulse ] [Pulse ]: Pulse, [ppm]: CO2 Concentration
: Pulse Rising (OFF -> ON), : Pulse Falling (ON -> OFF)
5. Graph Display Range
From the entire range of recorded data this line shows the range of data
currently on display. You can use the< List> button on the TR-57DCi to
zoom in and the < Ir> button to zoom out on data.
6. Date and Time of Cursor Position
The date and time of the current cursor position are shown here.

These show that data exists outside of the current display area. By using
the Operation Dial or the < Ir> / < List> buttons on the TR-57DCi, it is
possible to scroll up and down to bring data into view.
2. Number of Readings
This shows what number record out of the total number of records is being
currently highlighted by the cursor. (The above diagram shows that the data
being highlighted is 5th record out of a total of 168.)
3. Arrows
: Rising Edge Data
: Falling Edge Data
: Both Rising and Falling within 1 second
Events within an input voltage range of 0 to 30V are measured for
every 1 second and the time and date are recorded if any change,
rising (Lo->Hi) or falling (Hi->Lo), occurs and lasts for more than 1
second.
