I-Data 5250 ALLY - Manual (Page 38)

AGILE 5250 ALLY User’s Guide and Reference Page 1-16
Changing a twinax port’s emulation, like changing its address, causes the
5250 ALLY to end communication on that address, change the emulation,
then reestablish communication on that address. The 5250 ALLY will not
do this if the address is currently in use; the twinax address must timeout
before the 5250 ALLY will end communication on the address.
Note: Do not choose the 3812 or 5219 emulation if using continuous form
paper, such as fanfold paper (primarily used with dot matrix printers).
3 — Twinax Modes
The mode selection tells the 5250 ALLY what to do with the data it
receives from the System. If the 5250 ALLY will emulate one of the IBM
printers listed above, the user should select IBM printer emulation. The
five mode options are described below.
0. 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. 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 described above. Selecting this mode will also
usually require the user to set the twinax translation table option to
Table 07 (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 Table 03 (EBCDIC to EBCDIC).
4. Transparent. This is used only for diagnostic purposes.
5. Hex Dump. Hex dump mode will cause the 5250 ALLY to print all
data it receives as 16 hexadecimal bytes per line on the left column
of a page, accompanied in the right column by the 16 ASCII
characters they represent. SCS/DCA commands are represented by a
backslash (\) character. Refer to Chapter 5 — Maintenance &
Troubleshooting for a printout of a sample Hex dump.
To select a mode, press the MODE button on the 5250 ALLY front panel
until the LED reads “3.” After two seconds, the LED will display an
underscore (_). Then press the MODE button until the LED displays the
number of the appropriate mode (0-5). After two seconds, the mode will be
changed and the unit will return to Normal Operating Mode.
