B7210000 — The DAS setting is abnormal
Canon Medical (Toshiba) CT error code, reported by the MUDAT (Multi-Data Transmitting System) — optical data-transfer link.
What B7210000 means
On Aquilion RX and Aquilion ONE CT systems, status code B7210000 indicates: The DAS setting is abnormal. The code originates in the MUDAT (data transfer system) section of the MUDAT (Multi-Data Transmitting System) — optical data-transfer link. Severity level A1 (Alarm — high severity).
Reported action: Verify the DAS configuration against the documented settings before suspecting a board. The Aquilion 16 service manual documents three DIP switches on the Control-16 PWB — S1, S3 and S4 — that select DAS gain for the main detector array, the REF detector and the reserve detector plus the slice-thickness bits, each with a defined initial position; use the equivalent table for your system and restore any switch that has drifted. Then clear the fault, repeat the scan, and escalate for a DAS configuration check if it returns..
Toshiba / Canon Medical Aquilion RX and Aquilion ONE CT systems, raised when the DAS configuration reported to the system does not match what is expected. On Aquilion-family DAS hardware the acquisition chain runs from the Converter-16 PWBs, which digitise the detector signal, into the Control-16 PWB, which controls the acquisition sequence and drives the OPCONTA PWB over RS422 — and the Control-16 carries the switch-selectable DAS settings.
