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 would like to know if the DT80 can send a controlling voltage that is proportional to what is being read on an analog channel.

Hi,

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.

I tried creating a password with "password='xyz'" command, but I

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).
I see four ways th

My DT80 is not running on battery as soon as I remove the main power. DT80 status shows battery is giving 6.36V dc voltage. Please clarify. It is urgent.

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

Good Afternoon Roger,

The scenario is this: I would like to sleep for ten seconds and then wake up to gather data for 5 secs and then continue looping as above.

What is a suitable program should I use? I have tried this:

'JOB=SM
'COMPILED=2007/03/26 11:55:11
'TYPE=dt80
DT=\d
BEGIN"SM"
CATTN
'Spans and polynomial declarations
'Thermistor declarations
'Switches declarations
'

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

Good day Sir,

I want to talk about serial data input from the radio modem. For your information, I'm using RF Innovation product and the data transmitted from RFI radio modem is every 1 minute, with the baud rate: 9600.

Before this, I am using different data logger, the serial data input is looking find. But after I change to DT80, get something problem with serial data input. Sometime

Hello,

I need some help on setting up a PSTN connection to the DT80 for FTP download of files. Currently the DT80 is connected to a IG6000 via Serial cable 9->25pin adaptor.

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?

U R G E N T
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?

What other opti

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?

Good Morning,

I have an application where I am measuring quite small voltages (I want to be able to see a change of a few millivolts). I am running the schedule I'm using for logging every 250 milliseconds and a schedule just for a mimic every second.

How do I know if bounce is a problem? The relays are going great guns and surely this must cause some disturbance. I don't have a lot of
