The maximum cable length supported by the SN65HVD11QD is dependent on the baud rate and the type of cable used. As a general guideline, the maximum cable length is around 100 meters at 9600 bps and 10 meters at 1 Mbps.
To ensure reliable communication over long distances, it is recommended to use a shielded twisted-pair cable, keep the transmitter and receiver grounds connected, and use a common mode choke to reduce electromagnetic interference (EMI).
The SN65HVD11QD supports data rates up to 1 Mbps.
Yes, the SN65HVD11QD can be used in a multi-point configuration, but it is limited to a maximum of 32 devices on the same bus.
To handle bus contention in a multi-point configuration, it is recommended to use a non-return-to-zero (NRZ) encoding scheme and implement a collision detection and retransmission mechanism in the application software.
