2.5.3.1 Usage in a Garage
In a garage a common use case is to identify a defective MOST device. Therefor disconnect the device
that is assumed to be defective and connect the MOST150 Repeater instead. If the MOST ring works
properly the removed MOST device is probably faulty and should be replaced by a new one. If the MOST
ring does not work properly

the MOST150 Repeater can be used to replace one device after the other in
the ring except the controlling devices (e.g., headunit, timing master). For details how to evaluate the
defective device refer e.g., to the OEM’s work instruction.
Replacing by the MOST150 Repeater means the replaced device is substituted by an electrical short-cir-
cuit (i.e., the internal loop of the MOST150 Repeater).
Note: The extension functionality of the MOST150 Repeater is not considered in the use
case ’device replacement in a garage’ that is described above.
