9.1 General Operating Notes
Depending on the system type, up to 15 MCUs can be controlled, either individually or in groups, by up to seven
OCUs; Excalibur systems are limited to two MCUs and two OCUs.
9.2 Select Function
Excalibur OCUs have an electronic MCU selection switch and in this case the current position of the switch is
indicated using two LEDs (1, 2, 1+2).
9.3 Request Function
The selected MCUs must be requested by the OCU.
All the MCUs assigned to a selected switch position are always requested together. MCUs assigned to an OCU
as a result of a previous request remain permanently assigned to that OCU, even if additional MCUs are
requested by that OCU, and cannot be accessed by other OCUs. **
•
Only MCUs which are currently free can be requested.
•
MCUs which are not assigned to a specific OCU cannot be requested by that OCU.
•
Depending on the system configuration, one or more MCUs can be requested at the same time.
•
Sequential requesting of multiple MCUs, e.g. first MCU 1 and then MCU 2 etc. is also possible. **
