FNIRSI GC01: Install with stlink dongle

[webrex2000]

I can't see the Geiger counter in my pc win 10 then I saw instructions regarding stlink Dongle installation. The 4 pins have labels different from the instructions. From left to right I see clk dio gnd vcc....... I hope this is not a problem. What does mean to activate the bat file? Do I need to just double click the bat file and installation will start?

It should be obvious.
3.3v to VCC
GND to GND
SWDIO to DIO
SWCLK to CLK

The square hole by the battery is VCC

Yes, in the Gissio instructions the pin order is different from my device.

yes, if the contacts are connected correctly (according to the inscriptions on your dosimeter board), then stlink will give a green or red LED signal. Then run the .bat file on your computer and stlink will blink like a Christmas tree (green-red), the firmware progress will be available in the command line window (running line). Wait for some time, then your dosimeter will turn on itself and start clicking (informing about the gamma quantum that has flown in). Yes, it turns on itself even without a connected battery, because it gets power from stlink.

Ok I just double click the bat file and let see the show:) thank you

Hi i just updated the firmware and changed to the j321 tube, I used custom Hv profile but I have 91 volts on the tube, is this normal?

You can't measure the tube voltage directly with an ordinary voltmeter, because it have too low internal resistance (usually 10 MOhm). You need a 1 GOhm resistor in series with your meter and have to calculate the tube voltage.
