(see setting description format info here)
|Function:||Enables or disables the use of the start character |
|Post-initialization value:||0 (disabled)|
|First introduced:||Earlier than "baseline" V3.14/V3.51|
This setting enables the use of specific character code as the start character that can open the serial data block. Start character code itself is defined by the Start Character Code (S1) 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.
Use Start Character 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.
Care should be taken not to disable Use Start Character and Start on Any Character (SA) setting at the same time. No data will ever be accepted into the serial port of the DS in this case!
