I am working on a train project presently trying to program my dt80m3-3 with code to take in GPS data and use that data to monitor and record train speed and trigger appropriate data storage responses depending on train stop/run. Also want to record GPS position.
Can someone please assist with some appropriate coding. I am using deX-2.

Hi, I have a couple of DataTaker DT80's (one series 2, one series 4).

I plugged the S4 into a Windows 10 PC and Windows said it was installing a driver. Would this be DTusb or do I need to physically download it (where from?) and install it first?

I see from other posts that DEX 2.0 avoids the need for Flash. Where is the download for DEX2.0? Do I need to upgrade the DT80 firmware firs
Hi All

I goofed today, and set the logging interval much shorter than usual (2 vs my usual 15 or 30 seconds), ran out of memory half way through my trial and overwrote the early data.

I have downloaded and dumped the DDB - it's still missing the first two hours or so, so I'm fairly sure they are gone.

I was watching the data in a DEX2 dashboard while it was being collected - long shot

My DT80 series 2 just stopped responding
The sample light, disk and power lights are on but no display
It was a brand new logger (2009?) . I had updated to latest firmware.
It was working fine for about 3 weeks
Anyone got any ideas ? A hard reset has not fixed it

Hi @all,
I'm currently evaluating a DT80M Datataker Logger for the use with our SDI12 Moisture sensors. Logging the data works fine so far but I hit a strange problem uploading the data to an FTP server. Every time the Logger tries to upload data, it fails with some strange 'FTP: server out of sync (-3)' error.

Hi all, I last set up my DT85 on dex-2 about six months ago and have unfortunately forgotten how to do it. I am sure that the IP address and port 80 are fine but think there is something to do with the template that I am missing? Could any please provide me with the chronological steps I need to do as at the moment it keeps saying my DT85 is offline.

Thanks :)

In order to drive cooling fans for my system, I need a dynamic voltage output (2 different values) depending on measured temperature.
I have a DT80 series 4 logging temperature values.
I was wondering if the DAC could achieves this function using alarms?
I was only able to set the dac output value with manual commands, and the doculmentation is not really exhaustive on how to driv

I recently purchased a secondhand DT80 series4. The previous owner says it has had a factory reset. When I power up the unit it reloads the last current job. I have attempted to interact via dEX2 but can't get passed the username/password. I have tried to access via deTransfer but usb connection is refused. I have tried the reset button both single and triple. Suggestions on how to cancel current

I'm sure this is a simple question, but I can't find the answer!
I want to establish a direct connection to the command interface over a local network using my software. The final aim is to have scripts running on a linux web server retreiving real time measurements from the DT80.
The DT80 is happily running on a local network, and there is no problem connecting with deTransfer and other ut

I just started using the DT80 series 4 and when I tried to connect the logger and it have been only showing "Connecting to logger.....please wait"

-I've rebooted the device,
-Connected it locally by the usb
-Configured a new IP address to connect it virtually
-I used firefox mozille to open the virtual page and it only shows "connecting to device.. please wait" the DT80 is

We currently have DT80G devices in the field that upload to a FTP server. Is there a way to use a more secure upload channel?

I am still wrapping my head around this but there appears to be devices that can connect to MODBUS and could then handle the uploads. But I am not sure how all this stuff works and if I even technically understand how these things work

Dear DataTaker experts,
I am using DT85G Series 3, and before 2020, It was worked with dEX previous version without any issue. However, as it no longer work with flash player now I have to upgrade it to dEX 2.0 and firmware also upgraded to version 9.22

I have connected the logger using Ethernet cable and add the logger to dEX-2.
Now I cannot access the logger through the dEX-2 d

I have a requirement whereby i will have 2 DT85s in separate buildings both on different networks but pc has access to both networks, that i want to have 1 dt85 connected to the other or someway of having one download where all channels from both logger be on the one download.

I have a DT85G-3 device connected by ethernet to a Windows Server 2016 PC. I am using dEX-2 to communicate with the device.

The device will periodically connect, show me the clock time and show me its data if I go to the Data Explorer. I can see that it is running Software Version 9.20.8942.

In particular I am trying to see the Schedules loaded on the device, which seem to be getting sent

last week we encountered a problem with out DT80-3.
For no apparent reason it stopped logging, and on the display it said 'Cannot log - File error':

Do you know what can cause this, and how we can prevent it from happening in the future?

Best regards,

We are recently running DT80 and noticed that the DT80 screen shows "DT80 restarted SW exception". I checked the manual and it mentioned that "This indicates a possible problem with the DT80 firmware. Contact dataTaker Technical Support if you see this message". I couldn't find the contact of technical support. Please help! Thanks!

The DT80 logger is placed in a railcar to continuously measuring the temperature by thermocouple probes inside the refrigerator which is about -20C on the railcar. It sends the data through a modem to our ftp server so that we could remotely reads the temperatures. Since two days ago, we noticed that our thermocouple readings are "underrange" at the channels on CEM20 and "referror" on t

Following our system OFF/ON, the integrated DT80 has lost its configuration (no current job). This problem has already been seen on other DT80 that we use.
The DT80 had already "survived" previous ON/OFF, the data loss appears random.

Moreover, after the configuration loss it has been then impossible to reload the configuration of the DT80, even after freeing disk space.

We recently purchased the DT80-4 to work in low temperature to read T type thermocouple probes. It is connected with 2 thermocouples on the main module and 40 thermocouples on the CEM20 module. The main and extension module are both working in about -20C environment and 40% relative humidity. To calibration the thermocouples, we use glycol to simulate the low temperature situation. When we put so

I am logging 2 Pressure transducers (mV) and 2 digital counters on a DT80 series 2.
I have set the scan rate to 200mS. I have found that the DT
on about every 7th scan there is about 400-500mS interval
I know these are not high speed loggers but are there any settings I could use to speed up the readings. I only need to scan at the fast rate for about 20seconds during testing

Hi Please Help!

Offline Status : Developer Tools gives this error!


I know this occurs when you use port number that is common for other function such as port 7700 or the target port was not running on JSON script but still giving a response

but how do I fix?

(I have up to date firmware and software)

Good day, can you assist please, i installed my DT80 in a truck to record data. Logger stopped recording, i set limit at 30Mb and programmed to stop recording when limit is reached. When i tried to download data through Dex 2, logger just hanged, did not download. I tried USB, download started but when i pushed X to light up the screen to check status, download stopped and setup cleared. I urgent
