DS485TM/NOPB Frequently Asked Questions (FAQs)

  • The maximum cable length for the DS485TM/NOPB is dependent on the baud rate and the type of cable used. As a general guideline, the maximum cable length is around 4000 feet (1219 meters) at a baud rate of 9600bps, and around 1000 feet (305 meters) at a baud rate of 115200bps.
  • To terminate the bus in a DS485TM/NOPB network, a 120-ohm resistor should be connected between the differential lines (A and B) at each end of the bus. This is to prevent signal reflections and ensure reliable data transmission.
  • The maximum number of nodes that can be connected to a DS485TM/NOPB network is 32. This is because the DS485TM/NOPB uses a 5-bit node address, which allows for up to 32 unique addresses.
  • The DS485TM/NOPB has built-in error detection and correction mechanisms, including parity checking and automatic retries. However, it is still important to implement error handling and retry mechanisms in the application software to ensure reliable data transmission.
  • Yes, the DS485TM/NOPB can be used in a multi-drop configuration, where multiple devices are connected to the same bus. However, it is important to ensure that each device has a unique node address and that the total bus length does not exceed the maximum recommended length.
