Page 2-5CHAPTER 2 — ADVANCED CONFIGURATION
1. IBM 3812 laser printer ( SCS mode  5219 emulation)
2. IBM 4214-2 dot matrix printer
3. IBM 5219-D02 daisy wheel printer (default)
4. IBM 5224-2 dot matrix printer
5. IBM 5225-4 dot matrix printer
6. IBM 5256-1 band printer
To select an emulation, use the arrow keys to move through the menu to
the EMULATE: selection for the twinax device, use d and f to display
the emulation name, then press ENTER. For example:
OPTIMA: CONFIG:TWINAX1:EMULATE=IBM 3812
Changing a twinax ports emulation, like changing its address, causes the
OPTIMA to end communication on that address, change the emulation,
then reestablish communication on that address. The OPTIMA will not do
this if the address is currently in use; the twinax address must timeout
before the OPTIMA will end communication on the address. (See the
section Timeout later in this chapter for more information on timeouts.)
Modes
The mode selection from the menu tells the OPTIMA what to do with the
data it receives from the system. If the OPTIMA will emulate one of the
IBM printers listed above, the user should select IBM EMUL. The five
mode options are described below.
1. IBM EMUL. IBM printer emulation. This mode is the default, and it
activates the emulations above.
1. SCS DUMP. An EBCDIC hexadecimal data dump, this mode
simply prints a formatted hexadecimal report of the incoming
EBCDIC data, including a human-readable interpretation of the SCS
and DCA commands of the incoming data stream from the twinax
host.
2. 275 EMUL. Xerox 275 twinax protocol converter emulation. If the
user selects this, the user ordinarily should also select either 5225 or
5256 from the emulation menu. Selecting this mode will also
usually require the user to set the XLAT: option found in the menu
at OPTIMA:CONFIG:outport:XLTINFO:inport: to
275 E->A (Xerox 275 protocol converter EBCDIC to ASCII). If
the users printer is set for the EBCDIC character set, the user must
set the twinax table option to EBCDIC->EBCDIC.
