2.8.2 J400 – USB 2.0 Micro-B Connector
The USB 2.0 Micro-B Connector J400 allows simple RS232 communication between a host computer
and the Mars PM3 board using the USB interface. The USB 2.0 UART device U401 can be accessed
from the host computer using a virtual COM port driver to display debug messages or sending control
commands to the Mars PM3 board. The UART device is connected to the Mars module and the FX3
controller; make sure that the RX line is only driven by one device!
Normally the USB UART is connected to pins 34 and 36 of the Mars connector like the previous
versions of the Mars PM3. If DIP switch 4 of CFG-B is set to ON the UART will be routed to pins 153
