Hi All,

I am still battling away on the project that I mentioned in a previous post, but as I have progressed slightly I thought it would be better in a new thread. My application is using a DT80 (and now also a DT85) to log data and then upload to a web server via FTP.

I am struggling to make the FTP part work. At the moment I have a DT80 connected to the internet via a Belkin router,

Hi All,

Here's a quick question... I am looking into using some satellite telemetry to send a large bunch of data daily and want to minimize transmission time to cut costs, one sure way is to reduce the file size being sent.

The data being a csv file should be able to be "zipped" substantially before being sent - is it possible to implement some form of data compression in the DT80? If

Hi All,

I am currently working on a D T80 project which involves numerous DT80s uploading data to a web server via a GPRS modem. I think I can transfer the data by opening an ftp connection to the server and then unloading using 'U' directly into a text file on the server.

Is there any reason to think that this might not work? Also, is there any way that the DT80 can handle strings rece

Hi all,

I am running a DT85 with CANGate attached, GPS & CAN 1 connected to J1939 Vehicle BUS. How do I show what's snooping on the can in real time - so I can ensure I have the correct PGN & parameters for the things I am trying to monitor?

Thanks,
Gareth

Dear Sir,

We are facing he following problems in DT80 (being used in Automatic Weather Monitoring Station for acquiring weather information from various sensors)

DT80 is acquiring erroneous data from some of the sensors randomly.It acquires underrange or overrange data fro Temperature and wind direction sensors (resistance),Relative humidity and solar radiation sensors (voltage) etc. Th

Hi everyone,

I'm quite new to dataTaker. Sorry if my questions seem like rambling but would like to let you in on the details so hopefully someone might diagnose the problem.

Anyhow I seem to have problems connecting to the DT80 using my laptop. I have followed the instructions by the book so I can't seem to troubleshoot my problem.

I have a DT80 data logger and I have plugged it into our home router with an Ethernet cable. In about 3 months we are planning to go to England. How can I access the DT80 overseas? I need a very detailed description of what I need to do.

Yours truly,

Hi,

I am a basic user of DT80, till now I'm measuring temperature through DT605 and DT80.

Now if i want to measure the rotation of shaft and want to log that rotation (RPM) into datataker, how can i do that??? "Do i need any extra torque meter?"

Cheers

Hi,

Has anyone connected the new DT85 with a PLC through MODBUS? I am wondering if I could connect all my sensors to DT85 and send all CV data to a PLC using MODBUS TCP/IP or RS-232.

Will the MODBUS communication be real-time (every second) or PLC will only receive data based on my logging schedule?

Cheers,
Ken

Dear Sir,

One of our customer (Bharat Aluminium Ltd) is looking for DT80 or DT85 to log temperature and voltage data under 50 Gauss magnetic field environment (Pot flux process in Aluminium smelter plant).

We are not sure whether DT80/85 can work under this environment. However, we understand from customer that Aluminium company Dubai and Aluminium Bahrain are using dataTaker datalogger

I am setting up a DT80 to be accessed over the network, I can connect through Delogger, Detransfer, HTTP and FTP. I am wondering if there is any way to set a password for access to the dataTaker. Because the way the network is set up anyone could access it from any where and we want a basic level of access restriction.

Hi Members,

Does anyone know if there's a way to store an accumulated count so it can be read back as a starting point again following a Singlepush or power cycle on a DT80?

This isn't a concern for normal counts that are reset periodically or analog channels, but in the case of rainfall which is reset every 9am, if the DT needs a power cycle or Reset on site any total counts will be lo

OK my subject is a little misleading, but only a little. What I wanted to do was get opinions in that DT might take notice of (or maybe they already have).

As I see it there is 2 current ways of expanding a DT80/85:

Analog MUX and drive this from the digital outputs (cheap, but code to develop).
Hang a DT5xx/8x etc off the serial sensor channel (costly, complex code).

Good morning Roger,

In view of the latest DT80 firmware upgrades now available, since nobody else has asked the question regarding upgrading via a USB stick, I will.

How does one do it? The manual is very vague about the procedure with only a scant mention on p197. "There are also other ways you can upgrade your DT80's firmware (remotely by FTP transfer, or using a USB memory device, fo

It would help my users to be able to write a text program, put it on a thumb USB drive, plug it into a DT80, get a text file of data on the USB drive, and pull that out and analyze it with Excel at their desktop.

But I don't see how to do this. Am I right to understand it isn't possible? So, for people to use the DT80 as a standalone datalogger without connecting it to a PC, they would have

Hi!

I have a DT80 about 4000 km away. It was working happily until someone pulled the plug and the battery discharged. A month later, when someone went to stick in the USB device to download the data for me, they noticed the DT80 had been unplugged...

On plugging the power cord back it, the DT80 started up of course, but all the data now is rubbish - the DT80 is running - I don't know w

Hello,

Does anyone know the commanded needed in a batch file to tell DeView to convert .dbd files to .csv files? I have a batch file set up to import data into MS Access, but MS Access can only import text files (hence *.csv).

I know you can do that conversion by manually opening up DeView and click through the menu options to convert data, but I don't want to do that for each data file

Dear Sir,

Please let me know the dimensions of uppercase and lower case characters displayed in LCD display of DT80.

Please also let me know how long it will run on internal battery only (no external power) if we connect 15 sensors logging at 1 minute interval and whether 64MB memory is sufficient for that or not?

With regards,

Hi,

I'm interested in minimizing power consumption of my unit and note the LCD back light is continually lit when fed external power. Short of opening up the unit and disabling the drive, is there any other way of doing this?

I need to do this because the plan is to supply the unit from an external 12 volt source (solar power) and the light is not needed. As the logger is sampling every

Hi,

I've been through the DT80 manual and it looks to me that apart from the DB9 side connector for PC/modem comms, there is only one other serial port available.

If this is correct is there any way additional serial ports can be configured or are there any plans to expand the DT80? Do any of the other DT products support more than the DT80's number of serial ports?

Hi Roger,

Are you remember me yet? Long time no contact. I have three questions:

DT80 can use USB memory stick, what is the maximum capacity can it manage? Is popular USB hard disk compatible as well?


If I want to connect DT80 and DT500 together in a network, how to interface them? Can I get all data recorded from DT500 to DT80 then downloadable into USB memory in DT80 logger?

I'm measuring wind direction every second using a 360 degree pot (actually 0-355 as there is a 5 deg dead band) and am using the low current 200 uA excitation option in order to extract the variable voltage.

I don't think I can use the resistance method because of the dead zone of the pot. My first question is how long will the mechanical relay that is actuated every second last?
