TRANSLATE TABLES

General Information

The data stream from the coax host or alternate host is not sent directly

through the ALLY PLUS to the attached printer. Rather, all characters must

first pass through the appropriate character code translation table, even if

the printer uses the same data format as the source device. If the source and

printer formats are the same, the data is routed through a pass-through table

(ASCII from ASCII).
If the data formats of the two devices are different, a translation table is

selected that will convert the data from one format to another. The most

basic function of the ALLY PLUS is to convert EBCDIC (or host) data to

ASCII data one byte at a time. Each translate table has 256 entries

numbered 00 to FF. When a character is received by the ALLY PLUS, the

corresponding character from the appropriate translate table is substituted,

and that value is sent to the printer.
The ALLY PLUS has ten translate tables that can be modified by the user.

The tables are listed here with their table access number or letter:
