0 - SM ejectors closed.

3.3.1. Voltage Level Format

The voltage level is reported as an integer, with the units being

512

V. This may be used directly,

scaled arithmetically or scaled using the conversion tables.

When used directly the value may be considered as a fixed-point binary value, i.e.:

Bit

15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0

Sign Integer ·Fractional

To scale the value arithmetically simply divide the returned ‘integer’ by 512 to return the voltage as

either a REAL or INTEGER as required.

The input conversion tables may be used to convert the input value to engineering units, in this case

voltage. This is the recommended method where the value is not to be used directly. The full-scale

range for this number format is decimal ±256, corresponding to physical range –32768 to +32767.
