During a restart/reset, the BOOT DIP switch is used to determine whether to perform a firmware download from the SD/MMC
card or not.
BOOT DIP switch in position "ON"

BOOT DIP switch in position "OFF"

If there is no SD/MMC card in the card slot of the servo positioning controller and the BOOT DIP switch is in the position "ON"
(firmware download requested), the error 29-0 will be issued after a restart/reset.
This error stops any further executions. This means that communication via the serial interface (RS232) or USB is not possible.
