AWR1843BOOST: AWR1843BOOST: Out of box demo - send configuration via onboard UART port

Hello,

In my project I need to control the AWR1843BOOST using a microcontroller instead of a PC. In order to do this I would like to send the configuration via the onboard pins. I have been already informed that in order to obtain  results  via the MSS LOGGER  I need to solder R26 resistor. However I cannot diagnose what needs to be done in order to access the CFG_port UART using hardware. Does it correspond to the pins  RS232 TX and RX, so I would have to solder R166 and R169 or am I wrong?

I am using Out of box demo from SDK 3.03.

Thank you very much,

Kacper
