This setting defines the ASCII code of the start character that can open the serial data block. Start character must be enabled separately through the Use Start Character (F1) setting. Serial data blocks are related to routing the data in the serial-to-Ethernet direction. See serial-to-Ethernet data routing for more information. 


Start Character Code is irrelevant when the Start on Any Character (SA) setting is 1 (enabled) because in this case the new serial data block is opened by any character and there is no need to set a specific start character.
