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'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
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
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
I'm pretty new to Dex2 and DT and I'm trying to connect a power meter using Modbus RTU (RS 485) to Serial Port in my DT85. I've tried to write my own script with help of many code examples found in internet which didn't work. I also tried to program DT with Dex2 using graphical features it provides.

Code below is generated by Dex2:

And this is code I wrote which can't be eve

Hi i am looking to save to a CV channel the time stamp of when temperature sensor connected to the DT85 reaches a certain temperature 75C. therefore the CV channel will merely have the time this occurred

I have somehow locked myself out of my DT80M logger. In the Dex 2 software I set user level security to on by mistake. Now when I try to connect to the logger from DEX I get asked for a user name and password. I have guessed the default as datataker and datataker as defaults without success. How do I reset this I cannot see an obvious way.

I'm trying to add a ultrasonic RS485 sensor to my schedule on a DT85 ser 3 still using web interface.

The sensor has 4 wires: orange V+, black gnd, blue RS485-B, white RS485-A

My datataker supplier has kindly helped out by noting connect blue RS485-B to RTSY and white RS485-A to TxZ terminals.

I am a new user of Datataker DT85. Some of the thermocouple readings show a large instant jumping up (about 1~3°C) which is unreasonable and groundless although I do not change anything.

Also, when I turn on the humidity sensor power supply, the readings of the thermocouples are jumping about 10 °C.
Could you help give some advice about this problem? Many thanks.

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

We are using the DT85 to track temperature data by the second with both k-type TC's and RTD's. We are converting the C degree to F with Polynomial 1. What we are finding when we export our data to CSV is that the temperatures have 6 decimal places. Is there a way to round these up/down before exporting?

I have several DT80 running in radiometric stations. Now, I need to make modifications to the program of one the stations and seems to me I have to do it from scratch because I cannot modify the old program (which is very long...)

I want to program this part in the new "language":

I have tried to do a manual to insert it.
However, when I check the value of 1CV i
