ADM485JRZ Frequently Asked Questions (FAQs)

  • The maximum cable length supported by the ADM485JRZ is dependent on the baud rate and the type of cable used. As a general guideline, the maximum cable length is approximately 1000 meters at 9600 bps and 300 meters at 115.2 kbps.
  • To ensure reliable data transmission over long distances, use a high-quality twisted-pair or shielded cable, and consider using a repeater or a line driver to boost the signal. Additionally, ensure that the transmitter and receiver are properly terminated and that the cable is properly shielded and grounded.
  • The ADM485JRZ supports data rates up to 115.2 kbps.
  • Yes, the ADM485JRZ can be used in a multi-point or multi-drop configuration. However, the number of nodes that can be connected is limited by the total bus capacitance and the cable length. It is recommended to use a repeater or a hub to connect multiple nodes.
  • To protect the ADM485JRZ from EMI, use a shielded cable, and ensure that the cable is properly grounded and terminated. Additionally, consider using EMI filters or shielding on the PCB to reduce electromagnetic radiation.
