ISO7721: FDR

Part Number: ISO7721


I'm new to the ISO7721 device and have recently incorporated it in our design. We run a serial UART interface through this device.

Unfortunately it doesnt seem to be working. I see the data at the input pins but it does show up at the output side. e.g. pin 3 in TXD from MCU where pin 6 is the ouput. I see data at pin 3 but not at pin 6.

The voltage supply is fine within the range. What am I missing?

Appreciate you help!
