Graphic Chek Cod
(From page 161, page 173.) Specifies the replacement character to print in
place of any unprintable character that is received from the host. Choose a
hex character from 40 through FE. The character becomes the printer default
when:
•
The printer is powered off and then powered on.
•
An SGEA command specifies to use the operator panel default.
•
The Graphic Chek Err parameter is disabled.
The range is 40 through F4, and the factory default is 60.
Graphic Chek Err
(From page 161, page 173.) Allows overriding of the host setting for the
SGEA (Set Graphic Error Action) command. For more information about the
SGEA command, refer to the Coax/Twinax Programmer's Reference Manual .
•
Enable. The host setting for the SGEA used by the printer. If the SGEA
command is requested to stop on graphic errors, the printer will stop
when a graphic error is detected.
•
Disable. Ignores the SGEA command from the host. The printer does not
stop when an error is detected; instead, it substitutes the character
selected in the Graphic Chek Code parameter.
The factory default is Enable.
Hexdump Mode
(From page 166.) Hexdump mode allows you to place the printer into the "hex
dump" mode, in which the printer outputs a hexadecimal data stream. The
purpose of hexdump mode is to see exactly what data is received by the
printer, in order to debug forms, for example.
When enabled, the hexdump mode translates all host interface data to its
hexadecimal equivalent, then prints the hex code and its printable symbol, if
one exists. Figure 6 shows a partial example of a hex dump.
After the printer enters hexdump mode, all characters it prints (including any
in the printer's input buffer) are printed in two forms: as a two-symbol
hexadecimal code and as the character's printable symbol (if it has one). A
non-printable code is printed as a period [.] symbol. Up to 16 characters can
be printed per line of hexdump printout. While the printer is in hexdump mode,
it does not act upon any control codes, other than to print their hexadecimal
equivalents.
The 16 characters printed per line on the hexdump are formatted so that the
16 printable symbols are printed in columns 1 through 16. The 17th column is
blank. Column 18 contains either a p (PI line active) or a blank (PI not active).
Columns 19 and 20 contain the hexadecimal code for the first character,
followed by a blank. The PI line condition and hexadecimal code for the
second character are printed in columns 22, 23, and 24, followed by a blank.
The third through 16th characters are printed in a similar manner. The
hexadecimal code for the 16th character is printed in columns 78, 79, and 80.
