DS2411P+T&R Frequently Asked Questions (FAQs)

• What is the maximum cable length for the 1-Wire bus?
  The maximum cable length for the 1-Wire bus is 300 meters, but it can be extended up to 750 meters with the use of repeaters.
• How do I ensure reliable communication over the 1-Wire bus?
  To ensure reliable communication, use a dedicated 1-Wire bus pull-up resistor, keep the bus capacitance low, and minimize electromagnetic interference (EMI) and radio-frequency interference (RFI).
• What is the purpose of the VPP pin?
  The VPP (Program Voltage) pin is used to program the EPROM memory in the DS2411. It should be connected to a 12.5V programming voltage during programming and to VCC or left open-circuit during normal operation.
• How do I handle multiple DS2411 devices on the same 1-Wire bus?
  Each DS2411 device has a unique 64-bit ROM ID. Use the ROM ID to address and communicate with individual devices on the same bus.
• What is the operating temperature range of the DS2411?
  The DS2411 operates over a temperature range of -40°C to +85°C.
