Transmit -> [7][DSD_MODE], to change mode to PCM of unit 7
Responds -> [ACK 15 seconds][7], requested mode
Transmit -> [8][DSD_MODE], to change mode to PCM of unit 8
Responds -> [ACK 15 seconds][8], requested mode
Transmit -> [9][DSD_MODE], to change mode to PCM of unit 9
Responds -> [ACK 15 seconds][9], requested mode
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
Transmit -> [2][DSD_MODE], to change mode to PCM of unit 2 Responds -> [ACK 15 seconds][2], requested mode Transmit -> [3][DSD_MODE], to change mode to PCM of unit 3 Responds -> [ACK 15 seconds][3], requested mode Transmit -> [4][DSD_MODE], to change mode to PCM of unit 4 Responds -> [ACK 15 seconds][4], requested mode Transmit -> [5][DSD_MODE], to change mode to PCM of unit 5 Responds -> [ACK 15 seconds][5], requested mode
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.
Transmit -> [6][REQUEST_DSD_MODE] Response -> [ACK immediate][6], actual mode Transmit -> [7][REQUEST_DSD_MODE] Response -> [ACK immediate][7], actual mode Transmit -> [8][REQUEST_DSD_MODE] Response -> [ACK immediate][8], actual mode Transmit -> [9][REQUEST_DSD_MODE] Response -> [ACK immediate][9], actual mode
4)Check ADCs for mode change. This command allows the Transmitter to check the mode of the ADCs. If a unit has not changed the transmitter should go back to step 2 and repeat the command
Transmit -> [2][REQUEST_DSD_MODE] Response -> [ACK immediate][2], actual mode Transmit -> [3][REQUEST_DSD_MODE] Response -> [ACK immediate][3], actual mode Transmit -> [4][REQUEST_DSD_MODE] Response -> [ACK immediate][4], actual mode Transmit -> [5][REQUEST_DSD_MODE] Response -> [ACK immediate][5], actual mode
5)Command Master Clock to change frequency. Allow the system time to settle after this command with no RS232 activity, three seconds should be sufficient.
Transmit -> [SEL_FS], change to 96k
Responds -> [ACK 3 seconds], requested frequency Wait for 3 seconds
