Page 3-3CHAPTER 3 — CHARACTER CODE TRANSLATION

Twinax Translation

Because all twinax-generated data is in EBCDIC SCS format, the user
should select one of the EBCDIC tables (EBCDIC->ASCII,
EBCDIC->EBCDIC, EBCDIC->HP LJ, EBCDIC->PC, EBCDIC->PS),
depending upon the printer. Choose 275 E->A only if the twinax mode is
Xerox 275 emulation mode, and if the Xerox printer is configured for the
ASCII character set. Most users operate their printers in ASCII mode, so
EBCDIC->ASCII is the default.
When the data source is a twinax device, unprintable characters (00h - 3Fh
in EBCDIC) are removed from the data stream before the data is translated
with the translation tables. Any value of 0 is printed as the graphic error
action character (- by default). Thus, the first four rows of each table
usually need to be modified only for alternate host input.

Alternate Host Translation

When using an alternate host, the only function that the OPTIMA performs
is to send the data through a translation table. Although the translation
tables can translate both printable (40h - FFh in EBCDIC) and unprintable
characters (00h - 3Fh), the user will usually need to translate only printable
characters.

5250 OPTIMA Translation

Since all OPTIMA-generated data is in ASCII, the table selected for OPT
XLAT: should be either ASCII to ASCII or ASCII to EBCDIC, depending
upon the printer.
Reading Translation Tables
The left column of each table is a series of numerals and letters
representing the most significant digit of the hexadecimal input character
received by the 5250 OPTIMA. The top row of each table is a series of
numerals and letters representing the least significant digit of the
hexadecimal input character received by the 5250 OPTIMA.
The intersection in the table of the most significant and least significant
digits of the input character is the location of the output value that the 5250
OPTIMA sends to the printer upon receiving a given input character in the
data stream.
