B7100003 — Error in MUDAT (ROTSOT -3) — rotation-to-stationary transfer error

Canon Medical (Toshiba) CT error code, reported by the MUDAT (Multi-Data Transmitting System) — optical data-transfer link.

What B7100003 means

On Aquilion RX and Aquilion ONE and Aquilion S16 and Aquilion 16 and Asteion Super4 CT systems, status code B7100003 indicates: Error in MUDAT (ROTSOT -3) — rotation-to-stationary transfer error. 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: Treat it as a link fault, not a console fault: run the ROTSOT test (OPCONTA to GCIFA via the LPBA/ROT emitter and SPDA receiver) and compare the result with the OPCONTA test and GCIFA test, which check each board in isolation. Cross-reference the GCIFA and OPCONTA fault LEDs with the data-transfer error table to see whether the failure is a check-bit, sync, serial-communication or FIFO error before deciding which board or optical element to work on..

Toshiba / Canon Medical CT systems using the MUDAT optical link (Aquilion RX, Aquilion ONE, Aquilion S16, Aquilion 16 and Asteion Super4). The rotation-to-stationary (ROTSOT) direction carries the DAS pure raw data as 10 channels of serial data plus control data; the manual catalogues a family of ROTSOT faults on that direction, from simple check-bit errors to sync, serial-communication and FIFO errors.
