Hi Frank, Please check the capacitors inside, as they may need replacement after all these years. First and foremost, replace the two goldcaps (supercapacitors functioning as small batteries). These are the green components shown in the picture: Zrzut ekranu 2024-12-04 092745.jpg The current compone...

Przy sprawnych kondensatorach nawet całkowite odłączenie zasilania na 1-2 sekundy nie spowoduje restartu daty. Możesz to przetestować ręcznie odłączając wtyczkę i podłączając po 2 sekundach - data i czas powinny być zachowane. Zacznij od ustawień - nie włączyłeś przypadkiem trybu ultra-energooszczęd...

I ordered DS2431, tested it today and everything is working fine with v1.9.1
Pin4 and Pin5 from programmer are enough for read/write/erase.

You can send to me your chip so I can check where is the issue, with chip or with programmer.

Both should be the same. Do you have GX2431 in the same package as DS2431?
Please show me your connection, typical issue is swaped pin1 with pin3 in TO92 package, so users are connecting pin3 instead of pin1.
In REVELPROG-IS when you select DS2431 from database pin4 is ground and pin5 is IO.

Hi rsm, it should work in the same way. I'm connecting to DS2431 just 2 wires (pin4 to I/O and pin5 to GND) and it's working fine. Are you sure that chips are not faulty? Does it still work with your GX2431? Which package do you using? Does programmer pass HW test?

Można przerobić AdcX na AdcVccX (dodatkowy rezystor 1k 1% wewnątrz), ale w ustawieniach UKP można przypisać maksymalnie 3 czujniki NTC. DS18B20 można stosować też do cieczy, tylko trzeba dobrze uszczelnić lub zastosować wariant w rurce ze stali nierdzewnej. Osobiście montowałem w ten sposób że poświ...

It should be impulse signal from hall sensor,
LO <0.5V
HI >4V

1 - masa
2 - zasilanie 5V
3 - sygnał do podłączenia na AdcX

Datasheet pages 9-10 you have write procedure described in details. Write script for REVELPROG-IS which is working is shared here: https://forum.reveltronics.com/viewtopic.php?t=699 Please note carefully at comments in step 3: // STEP3 - Copy Scratchpad // Please note - you need to first execute STE...

I understand, thank you for sharing info about it!
