EasyMx PRO
USB-UART B
In order to enable USB-UART B
communication, you must push
SW10.3 (PD3) and SW10.4 (PD2)
to ON position. This connects the
RX and TX lines to PD2 and PD3
microcontroller pins.

PD2
If you need to use more than one USB-UART in your
application, you have another USB-UART B connector available
on the board too. Both available USB-UART modules can operate at the
same time, because they are routed to separate microcontroller pins.
USB-UART B communication is being done through a FT232RL
controller, USB connector (CN9), and microcontroller UART
module. To establish this connection, you must connect RX
and TX lines of the FT232RL to the appropriate pins of
the microcontroller. This selection is done using DIP
switches SW10.3 and SW10.4.
When using either USB-UART A or USB-
UART B, make sure to disconnect all
devices and additional boards that
could interfere with the signals
and possibly corrupt the data
being sent or received.
