I recently purchased a DT80 series 2 datataker, the seller did the installations for me on my laptop. At first i managed to go through the part 1 training exercise.

Later i could not manage to go over the exercise. From the laptop the information i get is:

Warning: could not open serial port
Warning could not detect baud rate for serial part
How can i resolve this?

Thanks

I have a DT80 in a remote area with only GPRS network available. Through GPRS, I want to open the remote DT80 web page. I cannot install a GPRS static IP on the DT80 because it cost $500 in my country and none of my customers can afford it.

So I am thinking of using existing dynamic GPRS and DDNS (dyndns.com). However from my existing noobish GPRS understanding, this system will not work. Ha

Hi,

I have to use an analog channel as a digital one. Do I have to supply power with an external source? (may be a 12V or 24 VDC)

Thanks, Dumnall

P.S. Any news about Windows 7 vs DeLogger?

We got a wave sensor and it only outputs serial binary data. Can dt80 read serial binary data and decode it into decimal CV?

Messages from the WaveRadar REX consist of fixed length strings of binary values which are sent over a half-duplex link. Output messages will utilize the data link for approximately 20 ms every 250 ms and are repeated every 250 ms (4Hz).

Any message sent to the rad

Hi guys,

I have a DT80 onsite permanently connected via Ethernet to a laptop running Delogger 5. The laptop is just showing the chart and the trend of a process over a couple of hours.

Whenever I access DT80 via a dial in modem, Ethernet connection drops out, and it needs to be manually reconnected by me which requires a site visit. Is this a normal occurrence or am I missing something

I cant connect DT80 through USB using Delogger5, it say

warning : connection refused Find device check failure
warning : datataker not found on connection
I had set what ever it told install driver... select the correct port but it fail, can someone help me pls thanks

*I am using Windows 7 64 bit.

Hi,

We have a number of DT80's in the field, the people that previously setup DT80's are no longer available. Is there a way to automate the collection of the running code (not the data) from the DT80's so I can get the field crews to recover the code?

Thanks,

Hello,

I am trying to take some measurements with some equipment that require a voltage input, and am having some trouble setting this up correctly with DT85 series 2.

According to what I have read, I thought I could do this by using the external input location. I have a regulated 10V source plugged into the External plug. and set up a channel for a load cell and configured with "E" for

I'm currently working on a 4 channels DT80 that is reading too low on the 10 ohm range. Is there a layout of the 4 internal variable resistors available? I'd prefer to not have to do the trial and error method, I haven't found anything in the available manuals.

Hi folks.

At the moment I am getting a signal back from my turbine meter into DT80 using a hall effect sensor and the high speed counter but would really like to do it with a magnetic pickup. My pickup outputs around about 50mV.

Is it possible to bring the magnetic pickup into DT80, read it as a frequency and then work out both a total volume and a flow rate? I have gotten both of these

Hello,

I am using a DT80 to sample an ultrasonic anemometer (Gill Instruments WindMasterPro) at 10 Hz, testing using DeLogger v5. I've also tested the serial connection using DeTransfer, after reading this forum - seems to be working fine.

I'm finding that I get a few seconds of measurements received at full rate (10 Hz). Then I get an error signal: 'serial sensor scan error at control

Hi all,

I have a DT80 inquiry for monitoring PN systems and was wondering is there an examples of this done within the applications notes.

Hi,

I tried this on script; s1=0,100,0,1"m" where my sensor output should in range 0-1v, but why i got -ve value on "m"? I thought the lowest it can be is 0m. How to only return minimum value is 0?

Hi,

I am programming DT85 series 2 dataTaker using DeLogger 5. My purpose is to log the change of state of some 80 inputs.I use CEM20 along with DT85 and use analog state inputs.

I don't need a continuous log, I only need logging when the inputs state changes.I use the alarms on all the channels, assign alarm numbers and set point 1 with conditional test as greater than or equal to set p

Hi,

Is it possible to control a pump having a 0-5V control wire using DT80? I would like to regulate the flow rate based upon the temperature of the flow stream. DT80 already monitors said temperature.

Thanks and regards,

Hi,

I'm trying to use digital channels 5D, 6D, 7D and 8D to monitoring digital status like I usually do with 1D, 2D, 3D, 4D. The channels from 1D to 4D work correctly but the channels from 5D to 8D don't work at all: they return digital status 0 (zero) with open and close circuit.

All the channels have the same command line so I don't understand why they do not work. There something tha

Hi guys,

We are still on the angular velocity problem. We are toying with the idea of using a rotary phase encoder and counting the pulses. With an encoder that produces 5000 pulses per revolution, it works out at 14.8 pulses per degree of travel. At 30 RPM that is roughly 14.8 pulses in 5 milliseconds.

Are we trying to get to much out of the DT80? We can go to lower encoder pulse rates

Hi Guys,

We are trying to log the change of a resistance versus time to calculate an angular velocity. I have managed to obtain a logging rate of approx 50 ms. Is it possible to go lower then this, and if so how?

Cheers,

Hi,

I wish to use the relay outputs A and B to power an external device when a certain condition is met. To test the functioning of the relay, I tried activating the relay by sending a simple 1RELAY=1 command and measuring the resistance between terminals A and B, thinking that the resistance should be close to zero when the relay is activated.

However, this was not the case (the multim

I am trying to use a dataTaker (DT80) to interrogate a device with a serial comms output (RS232). I am wondering is it possible to use a dataTaker to ask a device for a status check and then save the data from the interrogation?

For example if I wanted to gain the status of a modem via a hyperterminal session, I would use the code AT&V. I would then get the following output:
