# WIZ550S2E 모듈의 Serial 설정의 Stop Bits 2가 설정이 안됩니다

## Question

Asked by unsanglee on 2018-12-18 in Serial-to-Ethernet & ConfigTool.

WIZ550S2E configuration tool로 Serial Setting 설정에서
Stop Bits를 2로 변경후 Setting을 눌러 저장후 다시 Search하면 Stop Bits 1로 저장이 안됨
다른 파라메타는 저장이 잘됩니다

사용환경
WIZnet_Configuration_Tool_V1.03.jar
Firmware → WIZ550S2E_App.bin
