Sending Parameter 9 not catch in FMB920

Iam using FMB920, to detect analog input 1, but not catch ini this function:

        register(9, fmbXXX, (p, b) -> {
            double adc1 = b.readUnsignedShort() * 0.001;
            System.out.printf("adc1 %f%n",adc1);
            p.set(Position.PREFIX_ADC + 1, adc1);
        });

If you set the model name correctly and you still don't get it, it probably means your device is not reporting it.

Thank very much, done
