PARAMETER 34:
Test Character
TEST CHARACTER 01 MM/DD/YY HH:MM:SS
Background:
By sending a
Test Character
to the printer, the CP-220A is able to monitor
the printer's ability accept it, thus confirming the printer's connection to the
receiver and its readiness to receive subsequent data. Printers that are
turned off, disconnected, "off-line," or inoperative will be "failed" by the
CP-220A.
Virtually all alphanumeric printers respond to a set of numerical codes that
represent both printer control commands and the characters to be printed.
These codes are used throughout the computer industry, and are known as
the
American Standard Code for Information Interchange,
or
ASCII,
for
short. By sending one of ASCII's nonprintable
Test Characters
(designated
as [01] in this parameter), the desired printer supervision will be achieved.
It should not be necessary to alter this parameter, except for special
circumstances.
NOTE: Some printers may have a dedicated set of special characters for
codes outside of the standard
ASCII
character set. If so, the
recommended
Test Character
to be used should be what is referred
to as an "unprintable" character. Consult your printer manual for
more information about this matter.
Programming Procedures:
After entering
PARAMETER 34,
[TEST CHARACTER 01] will be displayed
and the [0] will be flashing. After reading the above, make any necessary
changes by using the
NEXT
key to advance the first character from [1]
through [F], as required.
Press the
key to advance the flashing cursor to the second character. In a
similar manner, use the
NEXT
key to change the second character.
Default:
ASCII
character [01] is the
Test Character.
Advancing to Next Parameter:
The next parameter in
Category B
is
PARAMETER 43.
Because it is not
sequential, it cannot be reached with a single press of the
key. To advance
to
PARAMETER 43
, press the
N
key.
The CP-220A displays the parameter just programmed ([PARAMETER
NUMBER 34]) with its first digit flashing, indicating its request for the next
parameter number.
You can reach
PARAMETER 43
by pressing the
4
and the
3
keys.
