How does the controller switch from R/C or serial mode?
At power up, the controller can be set to expect commands from the R/C radio input, the RS232 port, or from the analog voltage control input. The startup mode is one of the configuration parameters that is stored in the controller’s flash memory. However, even if it is not set to the RS232 mode, the controller will monitor the RS232 input lines and switch to the serial mode automatically if a predefined character pattern has been received.
