What B7220002 means

On Aquilion RX / V4-62R004 and Aquilion ONE / V4.2 CT systems, status code B7220002 indicates: Data transfer system (1) settings abnormal (MUDAT). The code originates in the MUDAT (gantry-to-console data transfer) section of the MUDAT (Data Transfer). Severity level A1 (Alarm — high severity).

Reported action: Compare the data transfer system (1) settings on the MUDAT boards against the configuration documented in the service manual — board settings are the first suspect after a board swap, a repair or a software version change. Correct any mismatch, power the gantry off and back on, then retest; contact service if the settings check clean and the code still appears..

Toshiba/Canon Aquilion RX (V4-62R004) and Aquilion ONE (V4.2) CT systems, on data transfer system (1) of the MUDAT link. Unlike the transfer-failure codes in the same family, this one reports the settings of that transfer system as abnormal rather than a broken transmission.
