DS2434 is 1-wire device with 16-bit unique ID, 2-byte battery cycle counter, A/D converter for battery temperature monitoring and 32 bytes eeprom for user data (total memory area is 160 bytes divided to 5 pages, but not all bytes are used).
Connection requires 3 wires:
- ground (pin 4 in programmer),
- data line (pin 5 in programmer),
- vdd (pin 8 in programmer)
This is how I connected it with REVELPROG-IS socket but you can also try to programm it in external circuit.

I'm also including updated memory database file for v1.8.5 (so you can find DS2434 in memory list). Please unpack this file and replace it in "%appdata%/REVELPROG-IS" only if you have v1.8.5 software version
