Jumper

JP4

(UART RESET)

JP7

(Reset imm./delayed)

JP24

(RST MCU)

JP35

(DTR / DTRx)

By default, the external reset is enabled and set to immediate reset while the reset by UART

is disabled.

Note:

While a reset signal is asserted the red Reset-LED D14 is lit.

During normal operation, this LED should be off!

If JP35 (DTR/DTRx) is set, the UART RESET jumper (JP4) and the according DTR/RTS

(JP3 and JP5) jumper have to be set, too.

If the reset LED is steadily on, check the power supply input voltage and the settings for the

reset-generation by UART.
