AWR1642BOOST: RS232 on AWR1642

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642

Hi,

We are trying to send the data from AWR1642 booster board over the RS232 port to an external board.

According to schematic,J6 Connector, Pin 5 & Pin 7 is used for RS232RX and RS232TX ,we connected  0 ohm resistors but unfortunately we didnt get the data.

We referred to the following post : https://e2e.ti.com/support/sensors/f/1023/p/672734/2476344 but it didnt quite give a clear picture

Can you please suggest how to acquire data through RS232 pins in J6?

Appreciate your quick response

Regards,

Divya Harikumar

    Hello Divya,

    Are you using the mmw demo application on AWR1642 or are you using your own application ?

    The mmw demo application sends the object data out on the MSS_LOGGER pin (comes on J5 pin 9 if you mount R26). The RS232 Rx/TX lines are used to send the configuration to the application. You also need to disconnect these lines from the onboard TM4C1294 device which is used by default to interface to these UART lines.

    Hi Vivek,

    Thanks for propmt reply!

    We are using SRR demo application on AWR1642 .

    We needed a bit of clarification on :"You also need to disconnect these lines from the onboard TM4C1294 device which is used by default to interface to these UART lines",which lines exactly should be disconnected?

    Regards,

    Hello Divya,

    I meant the RS232 Tx/Rx and the MSS_Logger lines need to be disconnected from the TM4C1294 since now you are connecting it to a separate board and not using the onboard TM4C1294 device for UART interface.
