After a reset, a secondary station shall alternate between supported data rates. When alternating between data rates, the data rate shall be held constant for 300 ms
. After every correctly received device scan command (see [1]) independent of whether it matches or not, at one of the supported data rates, that data rate shall be held constant for 1.5 seconds. After successful reception of an address assignment frame, the secondary station shall use that data rate until it is reset.
