BQ26220EVM-01

My customer has troubles to use the kit BQ26220EVM-01

The serial link  for the connexion to the computer seems to not run.

If you see the EV2200, the power of the PIC (µc) is +5V and there is no buffer RS232

How to use the serial link ? Do we need a level card adaptation ( (5V ß à RS232)  ?

Do you have the schematic of the serial cable?

Signals RTS CTS are connected or no and how?

Do we need a translator ?

Thanks for your answer.
