The maximum cable length supported by the DS2480BS is 100 meters, but it can be extended up to 300 meters using repeaters.
To ensure reliable communication over long cables, use twisted-pair cables, keep the cable shield connected to the GND pin, and use a common mode choke or ferrite bead to reduce electromagnetic interference (EMI).
The 1kΩ pull-up resistor on the DQ pin is required to ensure that the data line is pulled high when no device is driving the bus, preventing bus contention and ensuring reliable communication.
Yes, the DS2480BS is compatible with other 1-Wire devices, including temperature sensors, EEPROMs, and other slave devices, as long as they operate within the same voltage and frequency range.
To handle bus collisions and retries, implement a retry mechanism in your software to detect and recover from collisions, and use the DS2480BS's built-in collision detection and retry features.
