http://www.netiodev.com/GC10/gc10fw_rev2F.zipRe: UART specification - Martin Moore 2014/12/20(Sat) 01:14 No.575 Hi,
My GC10 has stopped sending data to the serial port. It no longer seems to be sending the /N command or my program that was working can no longer pick it up. I have checked all my wiring and it is all good.
It was working!
But it is not now.
Any idea?Re: UART specification - Martin Moore 2014/12/20(Sat) 01:35 No.576 Damn... My mistake. I had an Arduino Mega connected AND I connected the battery. So I suppose I have blown the main chip.
I have ordered another board because I need one. Is there anything I can do with the damaged board?Re: UART specification - NetIO official 2014/12/22(Mon) 11:46 No.578 I've experienced same mistake in the development and made some BBQed chips.
we should watch out for wrong connection.Increasing Tube Supply Voltage - martin 2019/03/01(Fri) 19:30 No.1113 Dear Sir,
I want to use a 500 volt pancake style Geiger tube. How can I easily change the voltage on the board to 500 Volts please.
I am not used to programming so some help in this would be very welcome.
We have bought a lot of these NETIO boards and they have proven to be very relaible (ECALOX Ltd and Looking for Heat - UK companies).
Regards - Martin MooreRe: UART specification - NetIO official 2019/03/03(Sun) 13:44 No.1114 Thank you for purchasing GC10.
Changing voltage is not so complecated.
All you need is update hvg parameter from UART serial line by sending 3 lines command. The procedure is
1) Connect GC10 with PC via UART line using UART-USB converter and make software link with serial terminal software (like teraterm).
2) Then cut&paste following 3 lines on the terminal.
stop
set hvg=68
save
(Don't forget to send return character on the last "save" command. otherwise it's not saved.)
3) Make sure the voltage with multimeter or oscilloscope with hi-impedance probe (if you had them).
and trim the voltage by adjusting hvg.
This hvg value 68 is for PCB ver 2.5. if you change it on previous version PCB, you have to change this value.
PCB ver
2.5 hvg=68
2.4A or under hvg=87
and we accept special order hvg pre-adjusted (and no tube?) version if you wish. please ask us.Re: UART specification - Martin Moore 2019/03/11(Mon) 20:16 No.1115 Thank you very much for your help. Programming was very simple. I have your UART interface and it all worked 1st time.
However, we are trying to use a new Geiger tube LND 7312 ( https://www.lndinc.com/products/geiger-mueller-tubes/7312/ )
But the readings are varying wildly across 6 NET-IO boards. We have double checked the programming and the wiring.
Do you have any experience of these Geiger heads and/or do you have any suggestions?
Kind Regards,
Martin Moore
Re: UART specification - kinoko 2019/03/12(Tue) 12:51 No.1116 No wonder. Just took a look at the datasheet. The electrical characteristics of LND7312 is different from sbm-20.
Espcecially "dead time" is signifficantly short, very improved.
it may perhaps need some adjustment of the curcuit parameters on detection part.
GC10's detection curcuit is optimized for SBM-20 which has slow pulse transition.
I assume some amount of detection pulse from LND are filtered as noise by C6. and
the threshold depends on each unit's variation of characteristics. this causes that.Re: UART specification - NetIO official 2019/03/12(Tue) 16:22 No.1117 Yes, kinoko you've got a good point.
there are 2 adjustment elements to adapt to an another tube.
(1) Make sure the actual generated voltage with multimeter(with hi-impedance probe). and trim hvg value to be most close to 500V.
(2) Find good value combinations of R7, R8 and C6 acquireing waveform of Re-shaped detection signal node (collector of T1). this node's transition should be fast
to reduce "Fold-back effect". This is important matter. GC10 geiger counter - Ian 2022/09/11(Sun) 04:19 No.1284 こんにちは
Do you have any plans to sell the "GC10 Geiger counter" again? Its considered one of the best available and so I would like to own one as well!
よろしくRe: UART specification - NetIO Official 2022/09/12(Mon) 13:19 No.1285 Hi there.
New version will be released on next month.
* Updated with modernized component parts and design.
* Board area 40% reduced.
* Onboard USB I/F.
* Drone payloadable weight (33g without OLED)
etc.

Re: UART specification - Umbrt 2022/10/31(Mon) 10:07 No.1307 Replaceable with raspberry pi pico W?Re: UART specification - NetIO Official 2022/10/31(Mon) 15:40 No.1308 Yes. same firmware works on Pico W except the detection LED.
The datasheet says some gpio assignment are changed.Source code - Simon Robert Wall 2023/01/12(Thu) 22:29 No.1320 I purchased the GC10next for a school project. The unit is very impressive. We plan to use the GC10next to measure radiation on weather balloon flight. We need to log the data from the GC10next and some other sensors during the flight (2-3 hours). Do you plan to release the source code for GC10next Raspberry P Pico. We hope to be able to modify the source code include data logging for the project. Is this possible?
Thanks for your help.
Re: UART specification - NetIO Official 2023/01/13(Fri) 11:02 No.1321 Yes, we have a plan to release GC10next source code on github.
now working on it. Please wait several days. Re: UART specification - NetIO Official 2023/01/16(Mon) 17:21 No.1322 Temporarily uploaded the source archive file here.
