This variable controls the output status of the amplifer. Setting this variable to off(1) will cause all the amplifier outputs to be shut off. Setting this variable to on(2) will cause all the amplifier outputs to be turned on. A value meaningless(3) will be implemented by the variables that represent a switch with write-only access. A GET request for the value of the write-only variable shall return a value meaningless(3). A SET request with a value meaningless(3) for the variable with write access shall have no effect and no exception is generated. A value may be used by the variables with both read-write and write-only access. The variables with read-only access shall be defined with the textual convention HeOnOffStatus.
