Good Morning,

In my laboratory i need to start different tests in different time. For example:

at time t0 will start the test n.1 eight hours long (n.1 trasducer);
at time t1 will start a second test two hours long (n.3 trasducer);
at time t2 will start a third test 24 hours long (n.1 trasducer); etc. etc.
I don't know, in advance, time t1 and t2, so i need to give the start manually

Hi,

I need to acquire data from edometric test. So, during a single test, i need to change the sampling rate, without stop the test (i.e. without interruption).

For example, sampling every 2 seconds for a minute; after, sampling every 60 seconds for the following hour; after, sampling every 30 minutes for the following seven hour. Altogether the test is 8 hour long.

If is possible

Hi,

I am currently programming a DT85 to monitor several temperatures. I need to reference an alarm if any one of 8 temperature sensors are over X sensor + 45 deg. Basically I want:

IF (CV2 OR 3CV OR 4CV)>CV10 {1CV=1} ELSE {1CV=0}
1CV IS ALARM STATUS 1 IS FOR ON 0 IS FOR OFF 2CV IS TEMP 2 3CV IS TEMP 3 4CV IS TEMP 4 10CV IS THE REFERENCED TEMP VALUE (5CV + 45)
Is there a guide to p

Hi

I'm trying to write a program in C#.NET to send and receive data from/to DT80 (Series 2). Has anyone done this? To connect I do this:

string result = axdataTaker1.comConnect();
I'm sure this succeeds ok because result returns

"1@9600,n,8,1,nofc"
Now I try and send the command "test" to the DT80. I do this:

string message = "test" + Environment.NewLine; string result = ""; tr

Hello, I've got a client who requires their DT80 to upload one day's worth of data daily at 6am. I've come up with a solution, but wondered if there's a better way to do it. My solution (use time based alarm to trigger upload, retry half-hourly on failure) is as follows:

RA"Take readings"

Hi,

How do you install the "advanced web interface" on a series 1 DT80? Do you use the series 2 software? I had a series 1 serviced recently, when it returned it had the Advanced Web Interface on it, I have 2 others that I would like to update so we can keep things the same.

Hi,

I don't usually use 4-20 mA loop sensors, but I am currently integrating a whole load of sensors from a PLC unit which hasn't been very effective into a DT80 system.

I have a number of queries:

I think that option C4 for wiring would be the best for me, and i am assuming that i can use the same power supply i am using to power DT80 for the *# EXT inputs?
I apply 12VDC +/- 1V t

Hello!

I have a problem with multiple schedules running parallel. The first one reads data via the serial sensor port at 10 Hz. The other one makes a lot of channel measurements every minute. Now every time the second schedule runs, I have missing data from the first.

I know that it is not possible to make two measurements at the same time, but the first schedule does not need any "meas

Hi,

I have a DT80. Is it possible to run a Job once by selecting an option from the front panel LCD menu? I have a job that will be scheduled to run every hour but when I am in the field installing the prob I would like to run the job on request to mount the prob at the correct height.

I don't want to stop the configured job from running at the right time and don't need to record the re

I am integrating a wireless module to a DT80, which has a serial connector, and we have integrated a small amount of code to ensure that the wireless device sends back a reading when polled.

However, when sending the command:

1SERIAL("{\er001}%f[1CV]")
The serial return times out, even though the buffer says it has read the correct figure and that there is nothing left in the buffer. If

I am working on a project using a data logger DT80, the project involves getting a thermocouple to sample temperature every second while at the same time to turn on a heater for 15 seconds and then turn it off for 15 minutes.

I have been trying to use an alarm and channel variable. I also would like this program to loop itself. This is my first time using a data taker. I was wondering if som

Hi guys,

I'm quite inexperienced in the dataTaker world. I have a DT80 V8.06. I would like to store data from a Metek USA1 turbulence device on the DT80. The data transfer is performed via RS232.

I'm using a sample frequency of 20 Hz. (= scan interval of 50ms). What "I have" already is this program code:

PS=RS232,57600,N,8,1,SWFC
P28=1
BEGIN "USA_V1"
RA"USA"(A:,DATA:OV:15MB)1SER

Has anyone created a custom HTML page where a user can select a program from a list and once selected a quick reset and away it goes ?

Hi,

I cannot find anywhere in the DT8x users manual any information regarding the detail of each message sent from a logger in fixed format mode. An advanced communication manual exists for the DT500 but I cannot find any similar information for our DT85-2. e.g.:

C,090696,2010/12/29,13:17:02,0.449707,1;41,"UNTITLED";0054;8E30
C,090696,2010/12/29,13:17:02,0.577148,201;42,"UNTITLED";0056

DT80 read by SCADA via RS485 polling: I am thinking of having DT80 getting data via RS422 from a multi parameter weather station.

And then having a SCADA interrogating DT80 channel values via RS485 polling. Thus DT80 have to be assigned with a unique RS485 address so the SCADA can differentiate between the DT80 among other devices in the RS485 network. Is this possible?

DT80 read by SCA

While trying to upgrade the firmware in two of the nine DT85's I get the following error. Is this something I can repair? DT8x BOOTLOADER V4.0 STARTED LOADING... FATAL FILE SYSTEM ERROR. Re-starting...

Hi,

Is there a way to adjust the LCD contrast? One of our units has a very dim display (no contrast) the backlight is working fine and I can just make out the word reset on startup but the display it too weak to read.

Thanks,

Hi Guys,

I haven't been around for a while as have been working on other projects. But here I am back, and thinking maybe things have moved on over the last couple of years!

I am installing a DT85 (MK1) in a vehicle, and wish to access the data remotely - ideally programming remotely as well, but would happily settle for data only. Mark Fisher @ Grant suggested FTP'ing the csv - which I

I have a number of DT81's that I have installed in the field logging environmental data. I have purchased a number of DT82E's for installation in the field and have programmed 1 as I did with the DT81's.

The Ethernet IP was enabled and I changed the IP address associated with DT82E from the Link-Local IP address that it possessed to a dedicated IP address. I lost communications as expected,

What is the largest internal compact flash card I can put into a DT85 series 2? I tried a 4 GB and it does not boot up.

I saw that and ordered a SSD-C04GI-4300 card. I installed the card according to the instructions, after that the power light comes on , the sample light blinks at about 2 Hz and the display wouldn't come.

I left it like that for a couple hours thinking it may be formatt
