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,
Pradipta

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

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?

It sou

Hi,

A few questions from a newbie regarding wind speed measurement. I have an ac generator wind sensor (RM Young) which gives only a few mV at low speed rising to several volts at high speed.

The frequency is the component read and I am seeing inconsistent results from a steady wind stream supplying a test bench sensor at around 4 knots. I see very steady results when connected to a com

Dear Sir,

We have some question about to operate DT80:

About the arithmetic operation. except for the expressions mentioned in the manuals, like some functions ABS(), Sn()... may we realize some more complex functions, for example: co variance?


About communications. we need some more flexible ways. We want some programmable module functions about RS232/485 communications. For exam

Dear sir,

How many channel entries does the DT80 allow? I can't find any information in the manual. Appreciates for your answer.

Best regards,

Hello,

I'm trying to connect to the DT80 via GPRS using two Wavecom Fastrack M1306B modems. I can dial out via Delogger or Detransfer to a mobile phone but can't seem to connect to the logger. Has anyone been able to configure these modems to work with the DT80?

I want to use the relay to connect a serial data line to the DT80 at the start of a schedule and switch it off at the end of the schedule eg.: 1RELAY=1 1SERIAL(...,W) 1RELAY=0.

The purpose is to prevent waking up the DT80 by serial data between the scans every 5 minute. It seems that the W channel option (no logging) is not allowed for 1RELAY, so how do I prevent the 2 1RELAY channels in the
