We are facing an issue related to ISO3082. When data is transmitted, Rx pin goes low for no obvious reason.
Please refer to circuit diagram as shown in Fig. 1.
Fig. 2 shows signals on RE and DE pins during data transfer operation.
Fig. 3 shows transmitted data and signal at Rx pin during data operation.
Yellow: Rx pin
Blue: Transmitted Data
Please let us know for any modifications in the circuit or any changes required to avoid this problem.
Note: We tried this using separated isolated circuit as well and our application end with different sets of ICs. Still the problem persists repetitively.
