Page A-15APPENDIX A — INTERFACING XEROX PRINTERS
The Xerox Menu
Each of the OPTIMAs twinax address ports (and other input ports) has a
submenu of options that are used to control the special modes of operation
used by Xerox printers. This menu can be found at:
OPTIMA: CONFIG: TWINAXn: XEROX:
in the OPTIMAs menu structure (where n is the twinax address currently
used by the port).
Note: The Xerox options are used only when the twinax address or input
port is configured for IBM EMUL. Xerox options are used for non-twinax
input ports only for diagnostic purposes.
Each of the twinax ports has its own set of these options, so multiple
addresses can be configured with different settings. This is an way to
support multiple types of data streams on a single Xerox printer, or on
multiple printers.
For example, the user can configure the OPTIMA with two twinax
addresses, both routing data to a 4235, one through the serial port, and one
through the parallel port. The 4235 could then be configured to receive
XDPM data through the serial port, and receive XPPM data through the
parallel port. This configuration allows usage of the printer in both modes
of operation simultaneously without mode switching.
UDK Character Translation Configuration
This option is useful only for twinax addresses receiving XDPM /XES data
streams. The OPTIMAs UDK character translation option controls
whether the OPTIMA will perform UDK character to Escape character
translation, or whether it should let the printer do the translation. The
option can be found in the OPTIMAs menu at:
OPTIMA: CONFIG:TWINAXn: XEROX:UDK XLT=
XLT UDKS This setting causes the OPTIMA to perform the UDK
character translation itself instead of letting the printer do it.
This is particularly useful in resolving UDK character
conflicts that can be caused by the OPTIMAs dynamic data
routing. In this mode, the OPTIMA will not pass the =UDK=
character assignment to the printer, but will store the UDK
character and translate it to s.
