content: Considering to buy the full set. Is the software useful especially in terms of measurement of inductance of D.C. Motor? Can't find any review of the software. Thanks

content: That site confuses me. Maybe I'm easily confused, and admittedly ignorant about the hole git scene. it's like aliens made this layout...I see two links to a teardown and datasheet. The teardown comes back to EEVBLOG forum. the datasheet is a 404.I found a small text link on the right that says serial-lcr and I can then click the text link that says blob or api.c - how utterly generic - and get some c kind of looking source code.What I do with that? Will the Arduino IDE compile it?I thought this device required some kind of IR-USB module, that was a black box lock unless you are a phd electchicken...I have this meter and would like PC interface. crude is ok...

content: Quote from: MrW0lf on April 19, 2017, 06:33:35 pmWhile that is true, we currently unfortunately have no one working on a GUI for this device class. This leaves only sigrok-cli to query device data, which means that there's no graphical display and it's up to the user to use whatever graphing tool they want to use. While flexible, it's probably not what fishandchips wants/needs.This may of course change in the future but until someone volunteers, that's the status quo.

content: Why spend $ 60 on the IR-USB module. I was able to connect to the PC with just one phototransistor and USB-UART(TTL) converter ?nd the software is available for free.You can use any Chinese USB-TTL converter, but I used the module with CP2102.Phototransistor L-53P3C.Here is a video demonstration:https://youtu.be/0tOvNqYPlwY

Does it do anything the handheld doesn't? Does it display data more quickly, or in a better format? Does it do graphs or anything?

content: @technogeekyI will try to answer.1.The transmission delay on the PC is very small. One of the advantages of software, is the ability to display on a large screen.2.The device has the capability of a dual display, But to display different information from the second display, you need to switch, The software receives and displays all the data at once.3.Some data received by the software have additional resolution that is not displayed on the screenFor some people, these features can be useful, but I believe that it is not worth the money that ask for the original kit.But if you make the adapter yourself (it cost me $ 2) Then it's worth it.

content: Hi, maybe you have a fake L53P3C phototransistor, or it solder wrong?Also maybe CP2102 damaged, or Pull-UP Resistor on RXI does not work or have cold join.If hardware is ok, try open COM port in Putty, see if there is any data.In software choose the right com port.Here is a software that works for me:https://goo.gl/ahJzZoThis is my video, and I'm not Russian, I'm Ukrainian.

content: Quote from: VA on March 15, 2019, 12:00:35 pmDon't think so: I get pulses from it when I probe it with a scope.I've used two of them: Collector to RXI and Emmiter to GND. Collector is the short lead and "flat" side of the capsule "rim".Quote from: VA on March 15, 2019, 12:00:35 pmWhen I connect it to the computer it instantly starts the COM port in the device driver and apparently works well. Regarding the cold joint, RXI reads 4.2V to ground... yes, this is one of those CP2102 boards that read 4.2V in the 3.3V portQuote from: VA on March 15, 2019, 12:00:35 pmSorry but I do not know how to do thatQuote from: VA on March 15, 2019, 12:00:35 pmAlready done: COM4 in my case, no "autodetect"Quote from: VA on March 15, 2019, 12:00:35 pmI'll give it a try but it is apparently the same SW...Quote from: VA on March 15, 2019, 12:00:35 pmSorry, mate!Thanks a lot for your answers!

content: I don't have a 3D printer so I made a simpler version.The photo transistor is supported by a neoprene foam pad identical to the one that comes with the DE-5000.Photo transistor:https://www.digikey.com/product-detail/en/kingbright/WP7113P3C/754-2137-ND/7318904Needed to add a 470 ohm pull up resistor on the Rx input of the serial to USB converter (FTDI based in this case but my CP2102 also needed one). The photo transistor acts as a pull down.Works great. Some photos are below.

content: Still not working!- I established connection with the UART via PUTTY: linked TX and RX and got readings. Put LOCAL ECHO ON and got double keystrokes, as expected...- I added a 470R pullup resistor between 3.3V and RX- Removed the DE-6000 SW and installed the DE-5000 SW from VA's link. I would swear they're the same!- Still get readings with the scope when measuring across the phototransistor.... but no reading in the SW screen. Dunno what else to do!

content: I do not see such pulses in my scope. The ones I see are AC only pulses with a few millivolts.Something's wrong with my UART and/or phototransistorThe UART board measures 4.23V in the 3.3V output so I suppose it is not working properly but I've read of many of these boards behaving this way.

content: PROBLEM SOLVED!As I didn't get any scope readings in the 3 or 4 volts magnitude as in your picture above (the pulses I got were in the millivolts range) I began to suspect the phototransistor was not working at all. In fact I ordered two L53P3C fromthis ebay seller(caveat emptor). None of them seem to work. I went to my local components store and bought a BPW77NB. As soon as I put it in the UART board I immediately noticed that, when attached to the DE-5000 in "PC" mode, the RX LED started flashing once every second. Now the scope reading is identical to that of JDubU's two posts up.Now it works like a charm, providing I set up a 470R pullup resistor as JDubU stated some posts ago.Thanks a lot to everyone helping!

content: you need to add a resistor, 470 - 1k, then it will work with the most of the phototransistors. Check it with your ocilloscope.Connect OUT to your USB RS232's RX pinConnect to 5 V / 3.3 V (depneding on your setting on the RSR232 USB converter)Connect GND to GND

content: Just to keep all the "DE-5000 IR interface" info in one thread, here is my successful setup.I've used the PT908-7C side-looking phototransistor (not from Digikey, so no guarantees it's original - but works reliably in this use case).Friction fit "chassis", CP2102-based USB-to-TTL UART with USB-C connector. 1kΩ resistor from RX to 3V3. It works with 10kΩ as well, and anything in between, but rising slope gets uncomfortably slow, so 1kΩ is better.The logic low level (when PT is open) is about 800mV, a bit high per CP2102 specs, but there must be good margin there, because with different pull-up Rs I saw it at just above 1V - and CP2102 was still reliably decoding the pulses.The logic high is around full 3V3 rail (about 3.45V).It will work with pull-up to 5V rail as well, CP2102's max V on any IO pin is 5.8V if I recall correctly, but I took a safer route.Drivers used are Silicon Labs' v. 11.3.0.176 (VCP drivers) - works well under Windows 11 Pro 23H2 with latest patches. To install these - download them from Silicon Labs, unpack, then go into Control Panel - Device Manager, find CP2102 there, "Update Driver", choose from local disk (point it to the folder to which you've unpacked the drivers).The software is from IET Labs website, for DE-6000, works well, just choose which COM port the CP2102 lands on.Don't forget to press the "Play" button in software and the "PC" button on the DE-5000 to see the results :-).I'm attaching a strip of photos and the PT908-7C datasheet here for reference.I hope this will help someone!
