Hi,
I need to use DT80M in area where there is no 3G coverage. At a similar location, we are using DT80 with external GSM modem connected to host port and using dial up connection to save the data remotely. Can we use the same approach with DT80M?

The SIM card also without GPRS service. It has only voice number and data dial up number.

i had a unit of DT80M, i want to connect to that datataker from other computer.

i'm using the fix ip sim card into the modem slot, and it shows that had a signal. so i assume it suppose can connect through other computer. is there a setting for me to connect that...

Tq in advance

Hi,

I am using the DT80M for a weather station and I don't want to use the in-built modem.

How to turn the modem off permanently ?

Because it keeps trying to connect, it sends these ghost strings - "SESSION FAILED - sim problem, will retry" error messages and throws off the server that I run downstream.

Kindly let me know how to disable the modem ?

Hi members,

with the attached program below I have trouble when I start report A with the internal keyboard. Sporadic the SW exeption occur with our without connected sensors.

I tested also to set the 3 serial commando strings between the analog section but without improvement.

Thanks for your comments

I experience this situation from time to time and there is no documented solution when the DT is operating in a remote monitoring situation.
What is the best and definitive way to prepare the DT to deal with this situation itself if it eventuates?
I want to avoid a hard reset though. That is problematic. Is there a "soft reset" option possible.

Hello,
I m trying to configure my own "CSV" format file. As far as I know, the predefined CSV format in DT is fixed, so that I cant for example remove the TZ column, or include a column with the JOB name... and so on. Thus, I have thought to use free format mode, and format data like a CSV (, separated values) and then upload to the FTP server with *.csv extension. However, using free format m

Hello,

I am having serious issues with the DT80M modem. I have got 2 systems deployed on field, configured and programmed correctly. When we come back to the office (after installing on field), we track the systems through the interface. Everything goes ok, but suddenly the connection is lost. So we had to move to the field and check what happened. Surprisingly, both the modem and the interna

Hello. I am new to the DT80M having just returned to DT's since the DT50 era in the early 1990's.

I am developing a remote monitoring and control strategy for an Off Grid Renewable Energy solution that must have communications redundancy built into it to move at least a bit closer to a "mission critical" level of communications confidence. This is best achieved by having two different methods

Retrieving Datataker data direct into an Excel Worksheet in real time for any Excel process including real time data graphing was once a very simple process, setup by using a Datataker supplied ActiveX Control [datataker.ocx].

Maybe it still is an easy process, but I haven't been able to find any contemporary documentation on the subject.

What made the dataker.ocx so useful was that it a

Hi members.

I need to do a preliminary evaluation of the quality of Cellular Signal available at a specific location to establish a "Signal Profile" for the location. This is an important preliminary test to gauge how reliable the communications will be. A week of data gathered and reported every hour by email will establish a reliable base line to evaluate.

I am thinking that the way to

Dear Sir,
we have one datalogger DT80. it is being used for quite a long time without any issues. recently we are facing communication issues with this system.
after sending the program it starts logging but after 5 to 10 minutes the communication ports get blocked and software hangs. earlier we used delogger 5. recently we up-graded the firmware with 9.18 version firmware. but the problem

Hi sir,
Currently, i work project using DT80M, but it is required 3 communications with other system:

Ethernet for internet
GSM for sms
Modbus RTU for connect to other system.
I found Modbus RTU support via USB port. So i would like to ask about this port support convert USB to RS485 as picture:

Hi

When trying to use the command window after clicking "Enable" I am unable to type anything in the "send" window. Does anyone know why this might be the case?

Dear admin,
Im using DT80M for my project, using functions:

modbus TCP master to poll two sensors
web server dex for remote access and retrieve data
serial sensor port for Request-Response SMS.
After reading manuals, help, forum, i wrote code for SMS, it's OK, modbus poll OK, Dex still access however very slow than before,
i don't know reason is my code or hardware not process fast enough.

Dear Admin,

When i worked with data reported from dex in .csv. In the code, i config the channel variable, example with 10CV(FF3) but it only display with three digits after decimal point, in .csv still saved not format follow FF3, normally 6 digits. Please give me the solution for this.

Thank you so much.

Dear Sir,

I just bought an DT80M unit. For the beginning I want to use channel 1 only and connect 3 independent analyzers (O2, CO2, and CO gas analyzers) that have each one the analog output of 0-1V.
Questions

there is possibility to connect all three to channel 1?
from the manual it seems possible to wire 3 analog (voltage) output to one channel but how exactly will look the diagram b

Hello,

I received the DT80M without rechargeable internal battery. The explanation from the provider was there was no room inside the device.
Please, can you recommend what kind of rechargeable battery I should buy (type, Voltage, Ah)? To connect the external rechargeable battery to device require special needs or simple connect to left side of the device?

Thank you,
Tibbie

Hello,
We plan to use more that one of DT80M unit. All the data collected it will be pushed to a FTP server in one specific folder.
Question: the first six digits of the csv file is the unit DT80M ID?
Example: 107767_CONFIG_20161025T154950.csv; 107767_CONFIG_20161025T125023.csv
