into user-specified units. (See note 2.) When input values are negative, they
are set using two’s complement.
Note 1. Only output scaling is supported by CJ1W-DA08V/08C Analog Output
Units.
2. This is possible only for a conversion time of 1 ms and a resolution of
4,000. The scaling function is not enabled for a conversion time of 250
µs
(500 µs for the CJ1W-MAD42) and a resolution of 8,000.
