CH Output
enable/disable flag
(1) Specify whether to output the D/A converted value or output the offset value for each channel.
on: D/A converted value
off: Offset value
(2) The D/A conversion speed is 6ms X the number conversion-enabled channels regardless of
whether the output enable/disable flag is on or off.

(2) Refer to the X9 column for the on/off timing.
YA
User range writing
request
[In offset/gain setting mode]
(1) Turn on this signal when the values for the adjusted offset/gain settings are registered in the
Q66DA-G.
(2) Refer to the XA column for the on/off timing.
Refer to Section 4.6 for offset/gain settings.
[In normal mode]
(1) Turn on this signal when restoring the user range.
(2) Refer to the XA column for the on/off timing.

(2) Refer to the XB column for the on/off timing.
YC
Set value change
request
(1) Turn on/off this signal when increasing or decreasing the analog output value during adjust-
ment of the offset/gain settings.
(2) The analog output is incremented or decremented depending on the value set to Offset/gain
adjustment value specification (Un\G24).
