3.4 Allocation of buffer memories (BFM)
In buffer memory locations (BFMs) marked
with an "*" data can be written from the PC
using the TO command.
For buffer memories (BFMs) without the "*"
mark, data can be read to the PC using the
FROM command.
Before reading from the analog special
function block, ensure these settings have
been sent to the analog special function
block. Otherwise, the previous values held
in the analog block will be used.
The buffer memory also gives a facility to
adjust offset and gain by software as well
as by panel switches of the FX-4AD unit.
(see note 3)
Offset (intercept): The analog input value
when the digital output becomes 0.
Gain (slope): The analog input value when
the digital output b1000.
