Dear Sir,
Pl let me know how to communicate DT85 with Tablet and access dEX Software using (through Chrome or other web browser) Tablet.
What should be the minimum hardware and software configuration for above case?
Regards,
Gpradipta
I have tried to set up a daily schedule to save newly acquired data to a USB memory stick.
I set this up in dEX configuration builder by adding a new schedule to run every day at midnight, then added a manual channel with the command
COPYD dest=A: format=csv archive=N src=BD start=new;
If I issue this command in the command window, it successfully saved data to the USB device.

Dear all,
We use a device from http://www.soilmoisture.com/TDR-Equipment/ (all 3 types) for mesurement 16 channels of water content with time domain reflectometrie system.
How can I control and readout this with a dEX - script at DT85.

Hello,
We can't read the legacy configuration back in the data-logger. In order to gain storage space for the installation files we deleted the job, data, alarms, configuration out of the B drive.
Should we create a new job first? Or should we go back to version 9.08 and forget about the new version (where can we get version 9.08 from)? Re-make the configuration which would take us a lot
Some questions about security settings on the DT85:
Are the firmware security settings documented in Part Q of the manual (PROFILE AUTHENTICATION ENABLED, USER, SIGNOFF, SIGNON, WHO) are the same as those set in dEX security?
Can more than one user be logged on at once (e.g. of the DT85 is accessed via an internet connection)? If not, what will a user see if they try and access the DT85 e

Hi,
We have always connected our DT85 (V6.22) to PC with DeTransfer or DeLogger using USB successfully. But now it can not be connected, because there has no USB Serial Port display in the Windows Device Manager when insert the USB of logger to the PC.
We tried to change the PC and USB, restart the logger, but still no any response received.
However,when we changed to use a USB to RS
Hello I have a DT85 which will not sleep. It has external power and I have set registers P15=3 and P17=300 but it stays on between 4 hour uploads. I see that if there incomplete jobs entered it will not sleep. How would I see these and how to delete these? Is there another reason for it not going to sleep
I have an Identical machine which is sleeping no problem.

I want to run my DT85 from a USB stick. My understanding is that this can be done by porting your program to a file called oninsert.dxc.
I am currently using DeLogger4 to create my job which I can run when connected via USB cable. For the life of me I can't find a way to create an oninsert.dxc file with this program.
Can DeLogger create this file or should I be using a different program?
Hi I have a DT85 which i am logging some temperatures & solar radiance.
I have 3 schedules the first is a standard logging schedule at 15 minutes it simply logs the radiance and temperatures.
the second is the same channel setup except I am logging every second and using CV's to accumulate the total radiance.

Our DT85 inexplicably neglected to log 7 minutes of data on a minute schedule. The last successful data record logged before the data loss had a time stamp of 12:00(noon). I glanced through the service log to see if there was an error around the time of the data loss and I found this:

Occasionally our DT85 will reset and we'll lose about 7 minutes of data. This shows up on the event log at the time of the data loss:

Hi All,
I have a series 3 DT85 v9.14. It as not been used much over the last year, and now just when I need it it seems to be giving me an error. As it collects data it will, all of a sudden, stop, lights flash, and the message SW exception appears.

Hello -
I am having trouble upgrading the software on a DT85 (I believe series 1). S/N 083710
I normally use DeTransfer for a newer logger I have but the "upgrade firmware" function is grayed out when I connect.
I tried two different USB sticks - one was an 8 Gig which I understand is too big. I also tried a freshly formatted FAT32 256meg stick and it didn't work either. It just reads

I need to measure an analog voltage of +/- 5 Vdc. I know I need to set the channel 10:1 attenuator in order to do this. When I configure the input range to '30V Input' on my channel in dEX and save to the logger, I get the error message as seen in the attachment.
I've tried doing the command through the command window in dEX also [9HV(GL30V)]. Then it seems to be accepted, but when I apply a

Hi Support,
I am trying to send the follow data to the RS485 port in HEX: 68 04 00 04 08 by sending \104\04\00\04\08
however it appears that only 68 04 04 08 is sent, the 0x00 in the middle was not sent.
Is there a workaround for this?
Thanks very much for the help

Hi,
I am using the +5V output to power a humidity sensor, I have used the command +5VSW=1 and set the logger up so that the 12V subsystem is continuously powered. However when I run the logger, the +5V works for short scan times (5secs) but for 15min scans the +5V does not switch on and so the sensor gives a bad reading.
Does whether having the USB connected affect whether the +5V SW is

We want to use datalogger to measure two channels - load cell and strain gage simultaneously, with a schedule such that, the data is recorded on a switch press and not at a fixed time interval.

I feel a trigger on switch press should be "Trigger on rising transition

After downgrading our firmware to 9.10.4890 per Datataker tech support recommendation our DT85 (series 3) is going through resets about every four days causing the loss of data during the reset.

Currently we have two schedules running; one 15 sec and one 1 min. In the 15 sec. we read 12 analog and 4 modbus c
We have a similar issue with the logger stopping to respond to be read through Modbus TCP/IP.

Dear all,
I have been experimenting using a DT85 Series 2 to measure relative humidity using the Wet/Dry bulb method. I have been taking the measurements using a pair of K type thermocouples - one of which is 'wet.'

I have contacted technical support in relation to this issue, but this is a more general question regarding current loops.
When you configure a channel for a current loop (as opposed to a current input), without any scaling, the logger should be 'reading' a 0-100% figure. This is related to the 4-20mA range of these current loop sensors. Is that correct?
If I have configured channels for

Hello,
I have searched high and low in the manual and FAQ without luck. The DT85 Series 2 has TWO power supply inputs for the switched excitation and shunt resistor. They are labeled exactly the same (EXT * and EXT #).
My question: Are these inputs tied together (is one EXT * electrically equivalent to the other)? Is one power input used for certain analog channels? If I am using switch

Hello,
I want to run the DT85 via USB, so therefore I need a USB-Driver. Unfortunately, the Driver on the page seems to be missing. Also, the dEX software platform, which I thought I could find is leading me to an "not found" page. Could you help me with that problems?
