Installing Simple Data Logger

When trying to install the ClickOnce version of SDL, you receive an error message that says that the “administrator has blocked this application because it potentially poses a security risk to your computer”

This is caused by the ClickOnce trust prompt configuration of your operation system. If you have administrator privileges, follow the instructions in this article to set the value of the “Internet” registry subkey to “Enabled” or “AuthenticodeRequired”.

You can also use our free TrustPrompt tool to configure this setting without having to edit the registry yourself.

Finally, you can also use the .msi or .exe installer available on the download page as an alterative to the recommended ClickOnce installer.

Using Simple Data Logger

No data is shown in the event log or written to the CSV file

If you believe that your device has sent data and that it should have been received by SDL, please press the stop button and follow the instructions below that apply to your situation. First, however, got to the settings tab and make sure that “show received data” is checked.

Case 1: No data or error message is shown in the event log (even after pressing the stop button)

No data received by Simple Data Logger

This means that SDL has not received any data from your device. The four possible causes are described below.

  1. Your device is not sending any data. Refer to the manual to confirm that:
    • Data transmission is enabled.
    • Your device is set to the correct data transmission mode.
    • There are no impediments for data to be sent. Examples: Many scales and balances are configured to send the weight only if or when it is stable. Legal for trade scales will usually not send values below the minimum weight.

    If the user manual does not contain useful information, contact the equipment manufacturer or the dealer who sold the device to you. To prevent them from attributing the problem to our software, we recommend that you test communication with another application as described in point four below.

  2. The settings in the input tab in SDL do not match the settings of your device. This is a very common cause when using a COM port. For data transmission to succeed, the following conditions have to be fulfilled:
    • You have to select the correct COM port. If you can choose from multiple port, keep in mind that the fact that SDL can open a port does not mean that your device is actually connected to this port.
    • All interface parameters (bits/s, data bits, stop bits, parity, flow control or DTR/RTS flags) have to match the settings of your device. If you’re using one of the “generic” profiles, it is very likely that you will have to change some of the interface parameters.

    Please refer to the manual of your device to find its default interface parameters, then confirm that these are the actually settings used by your device. Most scales and balances will let you view or change the interface parameters through their menu.

    If you’re using a pre-defined device profile in SDL (anything other than the “generic” profiles) and believe that our settings are not correct, please leave a comment. Please keep in mind that some manufacturers do unfortunately change the default interface parameters for their devices

  3. There is something wrong with the connection between your device and your PC. Examples:
    • Incompatible serial cables: Some devices require straight 1:1 cables, others need null modem cables while some unfortunately need special custom cables. The fact that you can physically connect a cable to your PC and device means nothing in terms of internal wiring.
    • Connectors that are not plugged in all the way.
    • RS-232 to USB converters with outdated drivers.
  4. You’ve found a bug in SDL. First of all, please make sure that you’re using the most recent version of SDL (compare the version number in the about tab with the changelog or the download page). Then, test the communication with your device with a different software. For connections using a COM port, you can use Termite or hTerm. For TCP/IP connections, try using PuTTY in “raw TCP” mode.

If you cannot receive any data from your device in these applications either, then then issue is not caused by SDL! Although we would very much like to help you, please understand that it is very difficult for us to diagnose problems with your device, configuration or connection remotely. How would we, for instance, know if you’re using the correct serial cable? As mentioned above, please consider contacting the equipment manufacturer or your dealer for support.

Should you still choose to ask us for help, please observe the guidelines posted below.

Case 2: An “ignored data” message is shown after pressing the stop button

ignored data message in event log

If an “ignored data” message followed by human-readable data sent from your device appears in the event log, this means that the terminator in the input tab is not configured correctly.

In the screenshot above, the terminator was set to ASCII code 4, which does not appear in the data sent by the scale. The correct terminator would have been 10 (line feed). If you cannot determine the terminator, try using a timeout instead.

If the ignored data does not seem to make any sense (e.g. “: <0><24>?<24>??<30>03`<30>030<30>030<30>030<30>03?”), then one or more of the following interface parameters are wrong: bit/s, data bits or parity. It is also possible that your device is not able to send data in human-readable ASCII format. In this case, it can unfortunately not be used with SDL.

You can see data in the event log, but it’s not written to the file

  • Make sure you’ve pressed the stop button to flush all data to the file.
  • ‍Confirm that the data shown in the event log is in ASCII format (i.e. you can read the data and don’t just see lots of non-printable characters shown in <brackets>).

SDL captures the wrong data

If you’ve selected a measuring instruments in the device tab, SDL will usually capture the first (decimal) number in each line. If this is not the measurement value you want, please try changing the output of your device. You can also customize the regular expression used by SDL to capture the data you want.

When polling the weight, an Ohaus scale replies with “ES”

Some Ohaus scale do not support the “IP” (immediate print) command. Try using the “P” (print) command instead.

Asking for help

Please observe the following points so that we can help you as fast as possible:

    • Please indicate the manufacturer and exact type/model of your device. Bad examples: “a scale” or “an Ohaus scale”. Good example: “an Ohaus STX421 scale”.
    • Please describe the problem precisely. “It does not work as expected” is far less helpful than “when I press the print button, only numbers in brackets show up in the event log in SDL (see attachment)”.
    • Mention if you’ve tried any of the solutions or steps from the FAQ above. Example: “I tried sending the weight from my scale to the HTerm terminal software, but it also doesn’t show anything”.
    • Attach a screenshot of the event log.
    • Send us the user manual for your device if it’s not freely available on the internet.
    • If we’ve successfully solved your problem, please confirm that the solution worked. This is important for other users with the same issue and it’s also a nice thing to do, particularly if we helped you solve a problem that was not caused by our software.

Really like the software, very simple and works perfectly the first time without even any changes to the generic device settings (used with a Prime Scales PS-IN202). Only change I would ask is that the window scroll down while data is being gathered so you can see data real-time. That’s a big one actually because it makes troubleshooting so much simpler. I hope you expand this software a bit to show a simple graph of the data and then an analysis screen with a simple drag bars to select areas of the graph to analyze with basic results of the… Read more »

Dear Sirs.
I did use the product SDL, wery well.
I wonder if it is possible to overwrite the data of the file (csv or txt) instead of writing in a new line.
best regards

Ryan

Every time I try to use this, it connects easily to the scale, but it will not print the data into the CSV file. Instead, when I click “Stop” it says “Ignored Data” in the log and shows all of the weights that I entered in the scale. What am I doing wrong? 10:38:31: Logging to file: C:\Users\BetsysStaff\Documents\portion control 2.csv 10:38:31: Connecting to Generic measuring instrument on COM5 10:38:31: COM5 opened: 9600 bit/s, 8 data bits, 1 stop bit, parity none, flow control none, terminator 10, timeout none, DTR on, DSR on, RTS off, CTS on 10:40:47: Cancellation requested by… Read more »

This solution worked great for a while, but since last month, the logger now records line after line of blank data when you hit “stop” which freezes it and prevents printing to file. It only works correctly when doing a small batch of data at a time.

Hello. I am having some difficulties setting up SDL with and ADAM CBK8 set of scales. I have used the default settings for the CBK type but I find that when I plug the scales in then multiple MSWord documents are opened with no text in any of them and no data is captured by SDL. SDL finds two com port options and it happens in either. I have tried various combinations of continuous print, auto and manual modes with accumulate on and off. Any suggestions? Many Thanks

Hello. This software seems very useful however I am having trouble getting data read out to my .csv file. I am using a Mettler Toledo NewClassic MS series load scale (MS4002S). I have the scale connected via USB (COM4) currently. I set up the program as suggested in the “How to Use Simple Data Logger” page. The first few times I tried to record data it would give me a single data point (when I hit “start”) – but always gave “4” so I’m not sure if this was actual data. When I did this I was using the default… Read more »

Is it possible to record data at variable time frequency. For e.g can we record data every 5 seconds for first 5 minutes and afterwards record data every 1minute.
