USB power meter/tester thread - YZXStudio, Power-Z, RDTech and more.

Thanks! Was wondering if the DataExplorer opensource app can also be configured to work with the ZL1100 load tester?

Hi and welcome to BLF Franky Tong. Thanks for the update. :+1:

I‘m not the developer of Dataexplorer, and I don‘t prefer Java. So do you miss a feature in my app?

Not working for me with ZL1100. Says time out after trying to connect, same as with the original version.

I will add variable timeout setting, now it is fixed 2 seconds.

But the other zy is working or also broken? Can you please try to connect with putty? So when putty is working, then my app is fault, otherwise it‘s your zl1100. Anyone else here with a zl1100 for testing?

Regards
Patrick

Edit: my zy only times out when I display the chart screen on it, other screens don‘t cause a Time out

Putty or any other terminal program works fine with the ZL1100. ZY1270 also works with the new version.

Welcome to BLF Franky. If you happen to find out who could sell the power banks, let us know. I would think someone could sell quite a few of them if there was a solid place to buy them from, especially if they were converted to English.

Yea, great to have you here Franky :crown: :+1:

Pardon my ignorance, how does one connect a serial-USB adapter to the ZY127x meters? Does the ZY127x meter have to have the bluetooth module installed for this to work? Or just need to buy some kind of serial-to-USB chip and (temporarily) connect it to certain contact points of the ZY127x meter?

I also have the ZL1100 load tester, and getting same error message as maukka above.
I actually haven’t tried to connect the ZL1100 tester to the computer yet before, so it’s my first time to test it connected to the PC.
(I’m not familiar how to use Putty, but I searched and downloaded a free software called RealTerm, opened the correct COM port, and it started to log results on the window); I had to use “Run as Administrator” to get RealTerm to work:

The above image correspond to reading of 5.0097v, 0.1000A, 0.9869Ah, 11.3322Wh

The “CPS” status window fluctuates between 740 to 1110 cps.
Not sure if this will help in debugging your great app.

Find the 4 solder pads near the edge of the main PCB. Starting from the square one, connect the 1st, 3rd and 4th solder pads to the GND, RXD and VCC of your serial-USB adapter.

Thanks for your reply! Just need some more clarification… somewhat newbie here.

Let’s say I purchase something like this (PL2303 USB to RS232 cable adapter)

Then I connect the pins:

“1” = GND
“2” = (no connection?)
“3” = RXD
“4” = VCC

Is that right?

That’s correct.

Thx for help (both of you)!

Please download v0.3 (link is the same from older post).

Go to settings and select your bps (115.000), I think this was the error (maybe 9600 is standard, and my zy is running at this speed).

I think you should now be able to connect.

Please report, thx Pat

Argh, I am frustrated! …because I’ve had my zy1276 for a week and haven’t gotten a chance to play with it, lol!

Lots of great info here, thanks all! Can’t wait to use it… :person_facepalming:

Sheesh, why does life have to be so busy that I can’t spend every day tinkering with my hobbies? Well, I did get my EBD-USB+ up and running yesterday, that’s good.

Works great!

edit: one problem, when trying to save the chart, it says “the system cannot find the drive specified”. I’m running the software from C:. Or was this feature still unfinished?

you can specify the path in the settings. then when connected, press play, then press pause, then go do the cart, then you should be able to save it, BUT yes, this feature isnt finished and tested, so please be patient.

The log .csv saves fine, just not the chart.

bug fixed, please download latest file. Chart is already in developing, but it is in working condition…

I notice here:

The ZY1276 firmware v3.35C (it seems to indicate 2017/10/22) includes a test for Apple MFi, unfortunately I’m not sure where the firmware might be available for download — I believe one has to join a China-based WeChat/QQ group to get the firmware update?

Can the latest ZY1276 perform checks for Type-C compliancy?
Or is it just a resistance test like on the previous models?

Any word on MFi-checking capability yet?
