3.5 UART”A”
(JP: 1, 2, 31)
One RS232-transceiver (U1, X3) can be connected to one of the microcontroller’s UART
interfaces.
JP1, JP2
connect UART 2 to the RS232-transceiver (U1, X3)
JP31
Some programs (e.g. Terminals) need a connection between CTS and RTS
Jumper
Setting
Description
Closed
SIN2 of the MCU is connected to UART”A”
JP2 (UART”A”RxD)
Open
SIN2 of the MCU is not connected to UART”A”
Closed
SOT2 of the MCU is connected to UART”A”
JP1 (UART”A”TxD)
Open
SOT2 of the MCU is not connected to UART”A”
Closed
RTS and CTS of X3 are connected
JP31 (RTS-CTS)
Open
RTS and CTS of X3 are not connected
By default, UART2 is connected to UART”A”.
3.6 UART”B”
(JP: 6, 8, 32)
One RS232-transceiver (U3, X5) can be connected to one of the microcontroller’s UART
interfaces.
JP6, JP8
connect UART 3 to the RS232-transceiver (U3, X5)
JP32
Some programs (e.g. Terminals) need a connection between CTS and RTS
Jumper
Setting
Description
Closed
SIN3 of the MCU is connected to UART”B”
JP6 (UART”B”RxD)
Open
SIN3 of the MCU is not connected to UART”B”
Closed
SOT3 of the MCU is connected to UART”B”
JP8 (UART”B”TxD)
Open
SOT3 of the MCU is not connected to UART”B”
Closed
RTS and CTS of X5 are connected
JP32 (RTS-CTS)
Open
RTS and CTS of X5 are not connected
By default, UART3 is connected to UART”B”.
UART “B” can be used for serial asynchronous Flash programming.
