DS485MX/NOPB Frequently Asked Questions (FAQs)

  • The maximum cable length supported by the DS485MX/NOPB is 4000 feet (1219 meters) at a data rate of 100 kbps, but it can be extended up to 10,000 feet (3048 meters) at a lower data rate.
  • To ensure reliable data transmission over long distances, use a twisted-pair cable, keep the cable away from noise sources, and use a common-mode choke or ferrite bead to reduce electromagnetic interference (EMI).
  • The maximum number of nodes that can be connected to a single bus using the DS485MX/NOPB is 32, but it's recommended to limit the number of nodes to 10-15 to maintain signal integrity.
  • To terminate the bus properly, use a 120-ohm resistor at each end of the bus, and ensure that the termination resistors are connected between the differential lines (A and B) and the ground.
  • The recommended baud rate for the DS485MX/NOPB is 100 kbps, but it can operate up to 500 kbps. A higher baud rate reduces the maximum cable length, so it's essential to balance the baud rate with the cable length to ensure reliable data transmission.
