Topic : Pinout for old xprotolab

i want to use my old xprotolab without usb. Now i dont know how to connect the power. The manual describes a 6x1 pin connector , i have a 3x2 connector.

Edit: can i just use the +5v of the „back“ pins (besides the logic ins)? (The -5 is an output??)

Topic : Xprotolab plain - how to use it in a simple way

Hello,

I recently bought a "plain version". Problem: it is not running anyway, neither under windows (XP64) nor Ubuntu 16 nor Android.

Later I only want to use it with a tablet and the Oscilloscope software from NFX (Nick Winder), for now also this is not working. (but using a OTG cable). What about the two cables from Micro -->A-A--> Micro? Both OTG necessary?

But the LED is lighting and both the voltages can be measured at the PCB-pins.

How to install the ZADIG-driver? There is no explanation, what it does. It propably does'nt work because the device is not recognized by MS Windows resp. I believe this. Can this be true?

And at last: should Xscope show "Connected", when it is connected only without any other cables on it or not? What means the white cable on the picture at the "plain" page between pin 1 and 5? I dont understand, why there is a signal shown without any Channel input. Confusing.

And really at last: what mean the 6 empty holes near the usb interface? Can I use them?

thanks for help!

Fritze

Topic : Xscope and screen resolution + control hiding

Yes, this is giving me grief also on the Raspberry Pi; I hate to make everything else microscopic just to get access to the controls; even to turn it on and off.

 

One thing I did was to edit the /boot/config.txt in order to change the vertical part of my screen resolution to 800 which worked for my 1366x768 display.

The plain runs (almost) the same firmware. The features are all the same. You only need to control everything from the GUI.

Topic : Xprotolab Plain Manual?

I just got my xprotolab plain from Amazon and have it up and working, but I can't seem to find any documentation for it. The downloadable manual covers the xprotolabs that have a screen and input buttons, but not the headless "plain" version, which seems quite different.  Where should I look for a manual for the "plain" version?

Hi Gabriel,

 

could you at least acknowledge your defeat for us, your backers on Kickstarter?

Thanks for the credits!

I guess speaking 25 years of expirience on marine electronics repair! I was forced to develop some unorthodox methods to resolve hard issues. Some times I'm thinking to write a relative book!


The information you are looking for, is somewere in the user manual.

If I remember well you press K4 before power supply. Then appear few options, one of them must be it.

I guess you are going to calibrate it after charge pump replace.

Thanks for a good idea with external -5V.

Device worked well, so I decided to replace the charge pump it did the job.

 

Unplugged chennels now show 0.0035V. Device works!

Is there a way to calibrate it 0? Didnt found that part in manual.

Topic : Xprotolab as test Jig

So,

I was able to solve my above problem. I used the commands mentioned in the manual.
For e.g. to set square wave send command 0x62 (command 'b') 0x25 (AWG waveform type 37 dec) 0x02 (square wave).

Similarly apply this logic for other parameters.
Baud should be 115200.

Thanks

Topic : Xprotolab as test Jig

Hi

I want to use Xprotolab plain as test Jig to test my hardware. I want to use Xprotolab to generate following waveform:

Square Wave

time: t0 to t1 -> 0 to 60Hz

time: t1 to t2->hold 60hz

time: t2 to t3 -> 60 to 0hz.

This process is automated and should go on in loop.

To achieve this I was thinking of Using Arduino Uno. Uno shall send commands over serial port to the xprotoblab.

Can anyone please provide the serial protocol datasheet or the format of the commands and the serial data frame?

OR Is there any other way to achieve above task?

Thanks

According to your measurements most likely your charge pump is dead.

Yes you can place voltage to the output, BUT ONLY if you first power up your xprotolab. After test remember to cut -5V prior to shut down, and off course to have the correct polarity.

Is an unorthodox method, but the only one left to do.

-5V is better to placed gradually, and if you are able to adjust maximum current, put about 50mA.

While -5V is externaly applied xprotolab should work fine.

Is unusual to burn a charge pump, especially two in a row. Maybe is a good idea to check your circuit connected to xprotolab, to find cause of damage.

Topic : XScope shows 20V on empty channels

Thanks a lot for your feedback!

1. Resistance on charge pump output (pins 1,4) - 3.2 kOhm

2. Resistance on charge capacitor (pins 3,5) 0.35MΩ C=3.3uF

3. Measure the input voltage of charge pump (pins 2,4) - 5.2V

4. Measure directly output voltage of charge pump (pins 1,4) - 0.5V

If no volt, then, while circuit is powered place an external power supply on -5V

Is it ok to place 5V from external source to charge pump ground and ground from ext. sourse to charge pump out?



[agmihos 2017-10-27 06:08:47]:

I suggest you the following:
First, while power is off, measure the following:
1) Resistance on charge pump output (pins 1,4) . If resistance is less than 10Ω then probably you have shortcircuit at the output (accententaly soldered together pins), or damaged charge pump. Less like to have damaged capacitors C26, C27. If you have accintentaly place voltage to AWG, may the problem caused by a damaged TL064 (U3)
2) Resistance on charge capacitor (pins 3,5) . If resistance is less than 10Ω between or by any other pin of charge pump, then you have damaged charge pump. Less like to have damaged to capacitor C25.
If no problem found, power up circuit.
1) . Should be 5V. If not, problem is before charge pump. Check for a broken PCB line. If voltage is over 5.5V then the problem is power supply.
2) Measure directly output voltage of charge pump (pins 1,4). If you found -5V then check for a broken line after charge pump. If no volt, then, while circuit is powered place an external power supply on -5V. Be careful to place correct voltage and polarity. Also, after test completed remember to cut first external -5V, and THEN xprotolab power supply. If current is high, then a cheap infrared thermometer can help you to find the damaged part.

As stated on the manual, some options are not implemented, they have a note saying "For future hardware".

I believe a small 120V/12V transformer will be the best. Provide isolation and safe low input voltage.

Some dimensions are described in user manual, page 10.
You can find easily K1-K4 ground by a multimeter. Turn switch to "Ω", place one terminal to one of the GNDs on pin header, and search all others by the other terminal of multimeter.

I try to enable x10 probe by Serial.write command, sending the follow: b, 1, and 3.
I guess I should see pointer of Ch1 shift a digit to the the right in meter mode, which I don't.
Other commands work fine, so communication work properly.
Do I miss something?

Topic : XScope shows 20V on empty channels

I've already replaced negative voltage generator (TPS60403DBV according to BOM), but the new one also does not show -5V.

So I thinks it can be burned after powering on. If so? what component can damage it?

 

I have one more TPS60403DBV. Is there a risk to burn it after replacement again?

Input is 5V - OK.

 

D1 LM4040D20IDBZ pin 1 shows 2.048V
