Introduction to Advanced Body Electronics: byteflight: Diagnosis

Diagnosis of the byteflight is carried out using the Diagnosis Program. Since the byteflight is a star structure and not a continuous ring like the MOST there is a test module "Data transmission to the satellites" that can check communication between each satellite and the SIM module.

Any satellite that does not respond must then be checked individually using a separate Test Module.

Repairs to the byteflight fiber-optic cable are not permitted. However, complete cables between the SIM and the affected satellites may be replaced.
