Edit Translation Tables
Normally, there is no need to edit the translation tables. The character
translation tables activated by the Printer Driver and System Language
selections are designed to produce the same printouts as the emulated
IBM printer.
If you should need to make further adjustments, this section explains
the character translation process and how to modify the translation
tables to meet specific needs.
Character Translation
Character Translation diagram
LU1 (i.e. SCS) data stream EBCDIC characters are first translated into
DBC codes (Device Buffer Code). This is the internal character
representation in the AX-7 Cobra+. The DBC codes are then
translated into ASCII codes, which are sent to the printer.
LU3 (i.e. DSE/DSC/non-SCS) data stream DBC characters are directly
translated into printable ASCII codes.
The EBCDIC-to-DBC translation table is determined by the selected
System Language.
The DBC-to-ASCII table is determined by the selected Printer Driver.
