PARAMETER 17:
NAK
Programming Procedures:
When PARAMETER 16 is entered, [ACK 00] will be displayed, indicating
(via the use of [00]) that the [ACK] feature has been factory disabled – the
default arrangement (in which it is assumed that an Automation System is
not in use). If there is an Automation System, any ASCII value between [01]
and [FF] may be programmed to represent the [ACK], although ASCII [06]
is normally used to convey the ACKnowledgement character.
NOTE: Whatever ASCII character is used to provide the [ACK] must be
the same for both the CP-220A and the Automation System.
In any case, the first of the two digits will be flashing; use the NEXT key or
the MANUAL/PREVIOUS key to change the character, as required. Once
this is done, use the
either the NEXT key or the MANUAL/PREVIOUS key to change it, if
necessary. Subsequent movement between the two digits can be
accomplished through the use of the
Default:
PARAMETER 16's default disables the ACKnowledgement ([ACK])
character through the use of ASCII [00].
Advancing to Next Parameter:
After programming PARAMETER 16, press the N key to advance to
PARAMETER 17 – the next parameter in Category C.
The CP-220A displays the parameter just programmed ([PARAMETER
NUMBER 16]) with its first digit flashing, indicating its request for the
next parameter number. Press either:
• 1 then 7 , or
• then
• the

NAK 00
Background:
[NAK] is the computer representation of Negative ACKnowledge, an ASCII
character sent from a device receiving data back to the device that sent it,
to indicate that the received data was either invalid or unaccepted.
