OI or RC Data

I would like to create a custom dashboard program. According to the dashboard packet stream definition file, “The IFI Dashboard Viewer … changes the display window depending on the OI/RC jumper setting”. Which byte of the data stream indicates the OI/RC jumper setting?

Just look at “CTRL_C Bit 7 and CTRL_A Bit 4�?. If these bits are changing as defined in the specification, the data is from the RC to the OI. If these bits are not changing, the data is from the OI to the RC.
