Hi, recently I bought a GQ GMC-500+ on Amazon Germany, and I am very pleased with this device. In the meantime, I got my inspiration from this forum, and I just finished your first DIY, it works great. By the kindness of the support team, we have completed the second of the DIY. I just got the firmware update, Re 2.12. I thought it was ok, but I've seen it here on the forum that someone else had posted the same type of device, with the firmware update, Re-2.13, in which the control voltage of the tube by showing the value in volts on the display. I've asked for the firmware update, Re-2.13, I get it, but it didn't change anything to me, it looks the same to the voltage in percent. I think I'm doing something wrong with the DIY or on the PCB. I have a request if you can help me out with some expert advice. I attach a few pictures of the device. Thank you very much.

So voilą, here is my GMC500+ with the voltage indicator in the first line of the text screen. In the foreground 2x Autunite pieces and left and right my protective container.

@Geo-Johnny - You would have to contact support at GQ about the parts. |

Thanks for the information, it seems logical. Do you have dates and values of these additional components, so that I can retrofit DIY perfect? For me it is not a problem, I have the necessary equipment. |

Just a note 2.18 is basically same as 2.17 but with different HV calibration for older resistors. |

I have got the update Re 2.18 for the GMC500+ from the support and now the volts and percent display on the text screen is working - perfect. Photos from the screen and external voltage measurements for comparison will come soon. |

Yes, I think that I need a newer firmware. I have already written the support in this regard today and wait for an answer.
It is also a problem with the big time difference. When I go to sleep, the support is awake.
On my GMC500+, the inductance and the diode are missing in the upper left corner. Hopefully, the high-voltage display on the text screen will still work.
If I need the missing components, would the values be interesting?

Hi Stargazer 40, yes, you are right, that was the first DIY that I've done it and it has worked very well in the first moment. DIY the second, was with the divider for the High Voltage,ability to display the High Voltage. It had problem and I asked for the help of EmfDev and support. Both of the Diy, I bought the parts, not from GQ. Thank you.

Thanks Gelu, now everything is much more understandable. I will also try to get a new firmware upate. Sometimes I'm in contact with EmfDev. |

Hi Geo-Johnny, I'm sorry for the inconvenience, but if you look at the history of the topic, you'll see that I've accomplished one of the two DIY's, but the one with the divider of the High Voltage did not work. I was inspired by the topic of your Ver. 2.13, and I've asked the support team to make it to this update thinking that the problem of non-functionality is here. But it wasn't, it was a matter of some complexity, and with the help of his EmfDev, and the team's support, on this occasion, I wish to thank them one more time, we managed to solve the problem, and I got it with an update of the experimental and that of the Rev. 2.17. Thank you, I appreciate it. |

Hi Stargazer 40, I have the ver. 5.1 PCB, I'm going to post a picture of the PCB before making the DIY. I just want to let you know that I solved the problem with the help of EmfDev, and the support team. I'm going to post pictures of you with this problem. Thank you very much. I really appreciate it. Thank you

Make sure that these 2 pins are connected together. From the 2.59V and 3rd pin from the left of the processor.

Hi EmfDev, thank you very much for the suggestion, but I checked it out a long time ago, if there was a connection and that connection is. On the PCB U1 (Pin3,4) is connected to the CPU (Pin14-PA0 WKUP). I'm just curious if you looked at my post from before. There I have drawn two conclusions can be made: 1. the either the CPU does not have the appropriate program for the Control of High-Voltage and High-Voltage Displays. 2. or the circuit of the DIY's I've done , it has a problem. This device has been built with the DIY, that is a project for the future, and it's probably the version of the software is different. The CPU doesn't know what to do with the information received from U1 (Pin3,4), and I think that's the problem. Thank you very much for your understanding. I appreciate it very much |

Hi EmfDev, and I hope that the support engineers, in the following analysis, with which I post, to make that version of the software, so that I can read, a High Voltage Display Tube 1. I'd like to think of it as a version of the software to the current Re 2.13 can make control of the High Voltage on the Tube 1 . Now, in the wake investigation that I've done, I can't be sure that it is up and running. I look forward to the resolution of the problem. Thank you very much for your help, I appreciate it.
Hi, I'll be back with our next analysis which I have made to Control the High Voltage (DIY), on the Tube 1 M4011. What do I need to take Control of the High Voltage? The CPU analyzes the value of the High Voltage with the help of. Pin 14(PA0-WKUP). If the Tube M4011, asking for an increase in consumption, the value of the High Voltage tends to decrease, then the CPU takes the decision to increase the number of pulses in the base of the transistor U1 through Pin61 (PB8 I/O). We have simulated the collapse of a High-Voltage by measuring it with a DMM at the end of the Tube1. I haven't seen any reaction on the part of the CPU. I think that the CPU doesn't know how to respond if you do not have a built-in program, or if the wiring (DIY), it's not working. I'm posting below the photos of this test. Thank you.
P. S. the Setting of the Voltage Tube1 is at 13% (359 volts to be measured with the probe of a High Voltage.)

Hi EmfDev, thank you very much for your help. The resistor has a value of 1GOhm. If you go back to my first post, and you're looking at the second picture, you'll notice that I've written down the values, in volts, as measured with a DMM with a 10MOhm impendanta of the input. The value of the High Voltage 358 is a high-voltage, I measured it with the probe of a High Voltage, with the ratio of 1/1000. I'm posting a picture of what I have written above. Thank you very much for your understanding.
P.S.The scope of the DMM is set to the manual is 2 volts.
And one more detail, the value of the volt after resistor of 1GOhm, as measured by the probe, a high voltage is 0.0036 volts. If you might be missing the resistor R4 of 10MOhm on the PCB, the value in volts as measured with a DMM it would be a 3,59 volt. I think the hardware is ok, and I hope to be like that. Thank you.

Hi EfmDev, unfortunately, the versions of the software, Re 2.12, respectively, in Re, 2.13, on which I have received from support, it didn't solve the problem. It does not exist in the menu, the function of the High Voltage Display. Re-uploaded the images and some other pictures. Thank you very much. I really appreciate it.
I notice that the photos don't load, I don't know what it is. In the second picture, I measured it with the oscilloscope, the shape of the signal on Pin 4 Of U1, to the CPU
I've done it, I'm very sorry for the inconvenience. I was wrong about the resizing, I'm sorry.

Hi EmfDev, you're welcome. The first DIY is working perfectly, what's the second DIY, I don't work yet. I'm still not clear if I missed something. Add a couple of pictures with measurements taken on Pin 4 Of U1. Maybe you can help me to fix the problem. Thank you very much.
