2)
Command ADCs 2, 3, 4 and 5 to change mode, the units may take up to
15 seconds to complete this command (if the previous mode had been
DSD the FPGAs need to be re-loaded, which takes time). There is no
need to wait prior to moving on to step 3

Check DACs for mode change. This command allows the Transmitter to
check the mode of the DACs. If a unit has not changed the transmitter
should go back to step 1 and repeat the command.
