Multiplex MLink (MSB)
The MSB (Multiplex Sensor Bus) is only uni-directional. You can only see the telemetry data,
but you cannot change parameters of the JetCat ECU.

For the values marked "alarm" in the above table, alarm thresholds can be set with the
Programming adapter (see section 2.0). In addition, also the MSB addresses can be set using
the Programming Adapter (see section 2.2.3) - an address double assignment within the ECU
converter is excluded. If an address has been set, which was already associated with another
value, than the other address is set to "OFF".
„--“ address ist not used.
2.2.2
Turbinestatus / OFF-Condition
To display the turbine status / OFF-Conditon, short messages are stored in the multiplex
transmitters of the PROFI TX series as well as in the "Schwanenhals" telemetry display.
In contrast to the status texts, the OFF Conditons are displayed inversely, with the exception of
the regular shutdown reasons:
- Switch OFF via RC
- Auto OFF or
- Manual (via GSU)
