DATAQ DI 2008 "start" command and read data problem
I only connect USB to my computer and double click the button change to CDC mode. (the LED is yellow) I try some protocol (for example "info o" , "slist 0 0" is work fine), however when I try "start 0" command the device return lots of garbled to me
WinDaq Stops Responding
We have a couple of DI-2008 modules that we use on multiple computers. I recently installed WinDaq on my normal work (Windows10) computer as the others were unavailable. The install went fine and the initial run of the software was fine. However after
Configuring the DI-1110 Digital Ports as Switches
All of the descriptive information about the DI-1110 says that all seven of the digital ports can be configured as switches, giving advice on maximum voltage and current, but despite considerable searching in Help, the manual and the available documentation, I cannot find out how this is done. I also noodled around in Setup mode and didn't find it. How is this accomplished?
Sample Rate
We have a DI1100, and we are creating a custom app for it using the .Net SDK. The app mostly works, but I'd like to slow down the sample rate. What is the definition of the value passed into the SetSampleRateOnChannels() function? I tried retrieving the min and max like this: ReadOnlyRange<double> lstSampleRateRange = (targetDevice.Channels[0] as Dataq.Devices.Dynamic.IChannelSampleRate).GetSupportedSampleRateRange(targetDevice); (targetDevice refers to the DI1100, and it is working) SetSampleRateOnChannels()
External Indication DI-4208
I'm setting up a DI-4208-E as a stand-alone logger. It is in an enclosure for environmental protection. I'd like to provide external indication when the logger is recording. I considered using light pipes from the onboard LED indicator, but I'd prefer
DI-1110 counter function with flow meter K factor
using DI-1110. I want to use a flow meter with a pulse output. Can I program unit to give me a output in gpm? I have a K factor for the meter, which gives me counts per gallon. Is there a way to do the math and display "GPM" units on graph?? thanks
how to correctly set DI-1100 srate with Linux
Hi, I'm using DI-1100 along with Linux for my research and I'm facing some issues when I try to read from the device. First of all, I'm following this documentation for protocol communication (https://www.dataq.com/resources/pdfs/misc/Dataq-Instruments-Protocol.pdf), and gently following this code (https://github.com/dataq-instruments/Python/blob/master/binary_comm/DI-1100/DI_1100.py). This code and this document (https://www.dataq.com/resources/pdfs/misc/DI-1100-Protocol.pdf, page 6) mention that

DataQ Timestamp off after Pause/Resume Remote Storage
I have "Remote Storage 1" enabled in WinDAQ and recording is starting and pausing based on the input on D1 of the DI-2008 as expected. However, the timestamp of data on resume of recording is in the past. I can see this while browsing the recorded data
Minimum Sample Rate when using Auto Start on System Boot
Greetings. I am trying to setup Windaq to auto-start when my PC boots up. I'm having decent success following the post linked below, with one exception. When Windaq launches, I get a popup telling me "sample rate [per channel] was raised to 0.0762 (minimum sample rate)." However, the data file I'm using to provide startup parameters has 4 channels enabled, a minimum sample rate of 0.00305/channel and a max of 100/channel. My desired rate is 0.016667 (1 sample per minute). From the blog: "[-F[d:path]setupfile]
DI-1100 documentation not up to date or wrong regarding several topics?

Using a DI718B on a computer with 2 Ethernet ports
Is there a way to get Hardware Manager to recognize directly-attached DI-718Bs when the computer has two ethernet ports? I'm trying to keep my DATAQ stuff segregated from the corporate LAN. Ideally, the setup would be: One Ethernet port connected to DI-718B for data acquisition. One Ethernet port connected to corporate LAN to access company resources. I've tried: Turn off Windows Firewall service Disconnected all Ethernet cables Assign first port static IP address Connect Ethernet cable from computer

Doubt on Python Serial Connection with DI-2008
Hi, I was creating a Python interface for DI-2008 and had some edge cases that confused me. When I create duplicate channels on the interface, meaning 2 'slist' commands with the same 16-bit configuration, I get 'stop 01\r\x00stop 01\r\x00' as a response
Stand alone mode file creation
I'm using stand alone mode on a 4108. The problem i have is that it is creating multiple files on the thumb drive. And when I say multiple I mean once or twice a minute. I'm ending up with thousands of files per day all with just a few samples in each.
DI-1100 building a 3 phase amperage logger
I work with CNC stuff a lot and sometimes troubleshooting would be easier if I could see what is happening on 3-4 different power cables at the same time. So I've been running down a rabbit hole and came to the DI-1100 as a possible solution. My current

I have two DI-808's I am trying to connect to the same network. I set the first one up to DHCP, and it found an IP address and connected to the network. The second one (also set to DHCP) however, does not get an IP address. The network is far from the
DI-2108 CDC mode binary encoding
I have a DI-2108 in CDC mode which I have recording a single channel with ASCII encoding. When I try to switch to binary encoding (encode 0) I am not getting anything back from the unit. Curiously, if I put it in binary mode and start logging, wait for a while, stop logging, then switch to ascii encoding (encode 1), it dumps a bunch of ascii readings before echoing the encode 1 response. Is there some kind of additional handshaking required in binary mode that I've missed? ASCII mode log: DI-2108

Question on programming with VB.Net
I am wondering if anyone knows an easy way to read from the DI-1100 and fill into a Datagridview? I am currently trying different ideas but I keep ending up with multiple values in one row for one channel. Thank you for your time and help.
DI-2008
Hello, What is the maximum speed of DI-2008 if all channels are used? Is it 200 Hz or 200/8 Hz? Also, may I use all 8 channels as +-10 V input (no thermocouples) without the unlock code? Thank you, best regards, Murray
DI-158U "Forgets" Default Setup
Randomly, the DATAQ model DI-158U will "forget" the default setup. Opening a "reference file" does not transfer the settings back to the way they were set up. This is causing us to redo the settings every time. Sometimes, opening WinDaq will open correctly with the user defined settings. Other times, it opens with the out-of-the-box settings. How can we make the default settings stick?
DI-2108P - Analog Inputs stuck on fixed value - not responding

DI-158U "Forgets" Default Setup
i may have originally put this in the wrong forum (DATAQ Hardware). Randomly, the DATAQ model DI-158U will "forget" the default setup. Opening a "reference file" does not transfer the settings back to the way they were set up. This is causing us to redo the settings when the program is opened. Sometimes, opening WinDaq will open correctly with the user defined settings. Other times, it opens with the out-of-the-box settings. How can we make our settings stick?
