Page D-5APPENDIX D — OPTEDIT
Input Ports
The OPTIMA has three twinax addresses, one parallel input port and two
serial ports that are configurable for use as input ports. To use a port for
input, in addition to activating it as described earlier, the user must choose
a mode (except for the serial ports), specify the output ports that each input
port will use, and select a timeout period. In some cases, the Xerox Special
Options selections will have to be modified.
Setting the Mode
The mode selection tells the OPTIMA what to do with the data it receives
from the system. If a twinax address will be emulating one of the printers
listed in Setting the Device Emulation Type below, the user should
select IBM Emul. The Parallel In port should use TRNSPRNT, except
for diagnostic purposes. The default mode for the serial ports is
TRNSPRNT, and it cannot be changed in OPTEDIT.
The five mode options are described below:
1) IBM Emul. IBM printer emulation. This mode is the default for
twinax addresses, and it activates the emulations described later.
This mode is not used for alternate host input ports except for
diagnostic purposes.
2) SCS Dump. An EBCDIC data dump. This mode is used to print a
formatted hexadecimal report, including a human-readable
interpretation of the SCS and DCA commands, of the incoming
EBCDIC data from the twinax host. This mode is not used for
alternate host input ports except for diagnostic purposes.
3) 275 Emul. Emulation of a Xerox 275 twinax protocol converter. If
this mode is selected, the user must also select either 5225 or 5256
from the emulation menu (described later). Also, for every output
port selected in Out To (described in the next subsection), the
Translate Info selection must be Twinax Port n=275 EBC->
ASCII (or Twinax Portn=EBCDIC -> EBCDIC if using a Xerox
printer in EBCDIC mode). This mode is not used for alternate host
input ports except for diagnostic purposes.
4) BLT Mode. A twinax mode used with specific applications. Do not
choose BLT Mode unless advised to do so by AGILE.
