About this setup guide

This manual covers the configuration and
operation of the Coax/Twinax Multi-Platform
Interface (MPI) feature for the IBM 6400
Line Matrix Printers.

The MPI feature enables either coax
attachment of the 6400 printer to, for
example, a S/370 or S/390 host, or twinax
attachment of the printer in an AS/400 or
Systems 3X environment.
In addition, the parallel port of the printer is
available for attachment to a PC, Network
Print Server, or other device attaching
through the PC parallel port.

What does the MPI feature do? The MPI
acts as a protocol converter, taking coax or
twinax data streams and translating them
into an ASCII data stream that the 6400
printer parallel ASCII port is set up to
handle. As you install and configure the
MPI, you are defining the translation that is
performed.

The MPI feature will normally already be
installed in the printer. If it is not, then
follow the hardware installation instructions
found in Appendix D.

IBM 6400 Printer

Once the MPI feature is installed, begin its
configuration with the instructions on page

2.

Switching between Serial ASCII and Parallel ASCII

To switch between Serial ASCII and
Parallel ASCII, the operator must
reconfigure the printer interface selection
from the operator panel by selecting a
custom set that uses the correct ASCII
interfaces. This is because the MPI
interface communicates through the
Parallel ASCII port.

— Configuring for port switching 12

Multi–Platform Interface Feature Operation Guide 1

Preparing for Configuration

With the MPI feature installed, the following
steps must be performed before it will be
fully operational. The MPI feature must be
configured, the printer must be configured
for correct operation with the feature, and
the printer must be defined to the twinax or
coax host. In addition, if the parallel port
will be used to attach another host, then that
configuration must be performed.

Pre-Configuration Checklist

Before configuring the MPI and printer, you
should review the following checklist and
answer each question. Answering these
questions will help you to configure both the
MPI and the printer.
! Will you attach the printer to the host

with coax or twinax?

! What coax or twinax printer do you

want the MPI to emulate?
Your choices for coax are:

IBM 3287 and 3262

Your choices for twinax are:

IBM 4214, 5225, 5256, and 4234

! Will there be a host device attached

through the parallel port? If so, what
ASCII emulation will this host device
use?
Your choices are:

Epson, P-Series, and Serial Matrix

! Is either Code V or IGP graphics

feature installed in the printer?

Now that you understand the environment,
proceed with the MPI configuration.

2 Multi–Platform Interface Feature Operation Guide

Quick Path

These are the basic steps you need to
complete to configure the MPI and the
printer:

! Set the MPI dip switches (Page 5)
! Set the printer configuration (Page 9)
! If configuring for coax, set the coax

buffer size using the rotary switch (see
Using Coax with the MPI)

! If configuring the MPI for twinax, set the

twinax address using the rotary switch
(see Using Twinax with the MPI)

Multi–Platform Interface Feature Operation Guide 3

Configuring MPI

To configure the Multi–Platform Interface
Feature, you use the twelve (12) dip
switches and the rotary switch located on
the Interface I/O (See Figure 1 ).

The MPI is configured differently when
connected with twinax or coax cabling. You
must know whether you are attaching via
twinax or coax.

important

The MPI is set to coax or twinax
communications depending upon which
cable is attached to the MPI. The default
value is Twinax. If the coax BNC adapter
cable, part number 08H7968, is attached to
the MPI, then coax is the default. If the
twinax auto-termination cable, part number
14H5335, is attached to the MPI, twinax is
the default. Therefore, if you want to
configure the MPI for coax, the coax BNC
adapter cable must be attached to the MPI

The dip switches allow you to select the
emulation of the printer, character sets, IGP
options, etc. If you do not know the type of
printer to be emulated, consult your Data
Processing department.

The rotary address switch is used to select
the coax buffer size or twinax address. For
both coax and twinax it is used to select
diagnostics.

Table 1 and Table 2 show the different
configurations possible. The selected value
is indicated, as shown on the Diagnostic
Test 7 Printout, by '=>>'.

To get a printout of the current interface
configuration, run Diagnostic 7. See the
section starting on page 48 for complete
details.

4 Multi–Platform Interface Feature Operation Guide

Configure the MPI by putting the dip
switches in the position that matches the
desired selection.

In the sample printout and the diagnostics,
the following convention is used.

0 = OFF or OPEN
1 = ON or CLOSED

note

After making MPI switch or cable changes,
the printer must be powered off, wait 15
seconds and then power on the printer in
order for those changes to take effect.

8 Multi–Platform Interface Feature Operation Guide

Configuring the Printer

In order for the Multi–Platform Interface
Feature to operate correctly with the 6400,
the printer must be properly configured.
The settings of Custom Set 8 provide
default values that work correctly with the
MPI feature to emulate a P-Series printer.
For other MPI ASCII printer emulations,
such as an Epson, you will need to change
the Custom Set 8 ASCII emulation.

Power-on the printer. If the power-on printer
configuration is not set to Custom Set 8, do
so now. Table 3 shows the most important
values: shuttle time out, latch data on, and
prime signal. If these printer configuration
values are set incorrectly, it may cause
erratic behavior. For a complete listing of
Custom Set 8, see Appendix B.

note

For proper printer operation, the ASCII
emulation in the 6400 must match the ASCII
emulation chosen for the MPI feature.
Check that these match and change as
needed.

See coax code map on page 22 and twinax
code map on page 34 to determine how the
coax or twinax host characters are
translated to ASCII characters.

note

Consult the printer's Setup Guide for a
complete description on how to setup your
printer.

Configuring MPI for Either IGP or Code V Graphic Feature

Those printers using an IGP or Code V
Graphics Feature must have the feature
installed and the printer properly configured.
Check the sample printouts of Table 2 and
Table 1 to see how to configure the MPI
when these two features are being used.

Further changes to Custom Set 8 values for
Code V or IGP emulation may have to be
made to support your host applications.
Refer to the Code V or IGP Programmer's
Reference manuals listed in Related
Publications on page xii.

Multi–Platform Interface Feature Operation Guide 11

Configuring for port switching

If you will be port switching with the MPI,
you must set the printer emulation used by
the PC application to match the emulation
you have set in the printer.

For example, when you have set the printer
emulation to 6400-Epson, your host ASCII
application, should use a standard Epson
print driver.

When you have set the printer emulation to
the P-Series emulation, your application
should use a standard P-Series printer
driver.

Multi–Platform Interface Feature Operation Guide 13

Coax Connection

To connect the coax line from the cluster
controller to the IBM 6400 printer, you must
use the supplied BNC Adapter (P/N#
08H7968).

Connect the BNC Adapter to the "HOST"
connector port on the Multi–Platform
Interface Feature I/O. (See Figure 2 )

Once you have securely connected the
adapter, connect the coax line to the coax
connector on the end of the adapter.

Before powering on the printer, it must be
defined to the host. For additional
information on defining the printer in the
S/370 and S/390 environments, refer to
Appendix A of this manual.

Power on the printer. At this point, the
SYNC LED indicating line activity will be on
if there is activity on the coax line. (See
page 75 for the location of the SYNC LED)

Send the printer a screen dump from a
terminal. If successful, send the printer a
print job from the host. In some systems,
the printer may not be configured for local
screen dumps. When the printer receives a
job from the host, the SYS LED will light
indicating a job in progress.

Figure 2 BNC adapter

attachment

important

The printer uses the 3270 data stream
format when connected via coax through the
MPI. The MPI supports LU0 (DSC), LU1
(SCS) and LU3 (DSE) types only.

14 Multi–Platform Interface Feature Operation Guide

note

Remember! If you make any changes to
cables, switch settings or the configuration
you must power the printer off, wait 15
seconds and then power the printer on
again.

LED Indicators

The Multi-Platform Interface I/O has two
LEDs labeled SYNC and SYS (see page

75). These can be used to determine line
connection status and host
acknowledgment.

When the coax cable is first attached to the
BNC Adapter, the SYNC LED will light,
showing that active line connection has
been made. If the LED fails to light, the line
you are connected to may be faulty.

When the interface receives data from the
host system, the SYS LED will light
indicating a job is in progress.

Multi–Platform Interface Feature Operation Guide 15

Coax Buffer Size

While connected to the coax line, the IBM
6400 Multi–Platform Interface Feature has a
built in buffer. The size of this buffer is user
configured by setting the Address switch
(see page 75 for location on I/O) on the MPI
I/O to a specified setting. Table 4 shows
the buffer size for each setting.

Coax Command Interpreter

To gain access to some printer features not
available on the host system, a Command
Interpreter has been built into the
Multi–Platform Interface Feature.

By using special control codes, you can
pass the hexadecimal codes to the printer
that access the ASCII features of the printer.
These codes allow you to transparently pass
any character or sequence of characters to
the printer.

These codes are Hexadecimal ASCII
commands and must match ones supported
by the printer and MPI ASCII emulation
selected.

The commands are initiated by use of the
logical not (¬) character. You can access
this character by pressing the Shift and 6
keys on your terminal’s keyboard.

Multi–Platform Interface Feature Operation Guide 19

coax command interpreter

Commands

The command interpreter is enabled after
the ¬ONN command is received.

The command interpreter is disabled by
sending a ¬OFF command. The default
power up state of the command interpreter
is disabled.

Table 5 gives an explanation of all the
commands available.

Table 5 Coax Command Interpreter commands

COMMAND ACTION

¬ONN Enable the command interpreter. Ignored if already on.

¬OFF Disable the command interpreter - Default, power up

¬HEX Hexadecimal pass-thru mode. Data following this

command is packed into hexadecimal pairs and sent to
the printer. The command may be terminated by sending
the "@" character. Any non-hexadecimal characters
(except the "@") are ignored.
Terminate Hex mode by sending an at sign "@".

¬FLS Forms Length Switch. This command is accepted only in

LU3 (DSE) mode. It will set the forms length (in lines) to
the value of the three digit number immediately following
the command. Top of form will be set to the current
physical line. The value must be in the range 000 - 127.
There may NOT be any other characters embedded and
the forms length MUST be three digits long.
Sending the FLS command causes the MPI to load the
printers VFU and set the Top Of Form to the present
line.

¬L03 or

Coax Code Maps

Data sent from the S/370 or S/390 host
computer to the Multi–Platform Interface
Feature is translated into the correct form
for the 6400 printer to understand. The
following sections show the maps used by
the interface to translate the various kinds of
host data into the ASCII printer language.

To translate the coax host character to
ASCII character, use the coax hex value as
the coordinates (grey column and row) on
the map. At that cell, is the ASCII translation
(ASCII hex value and character).

For example, a coax DSE hex value of 35
would be translated to ASCII hex 2B and is
the ASCII "+" character.

These maps illustrate the translation from
host code page United States to ASCII code
page PC850. Translation maps for other
code pages, such as United Kingdom, are
not shown. See Appendix E for Supported
Host Character sets.

Translating Host Code Page to ASCII Code Pages

Set the active printer ASCII printer
emulation as follows to correctly map host
code pages to ASCII code pages:

28 Multi–Platform Interface Feature Operation Guide

Twinax Connection

Before installing the printer into the twinax
environment, you should run the built-in
diagnostics. See page 48 for instructions
on running the diagnostics.

After the Multi–Platform Interface Feature
is running the built-in diagnostics you are
ready to connect the printer to the AS/400,
System 36 or other twinax host system.

Active jobs/devices

If there are any active devices on the
twinax line that the printer is going to be on:

1 Terminate the device immediately up

cable of the printer, on the twinax line.

2 Place on Hold any devices down cable

of the printer with active jobs.

3 SIGN OFF any active terminals and

terminal type devices down cable of
the printer.

twinax connection

note

"UP CABLE" describes any device that is
physically located closer to the Host System
on the twinax line. "DOWN CABLE"
describes a device physically located more
distant from the Host System on the twinax
line. For example, if this printer is the third
device on the line, the immediate "UP
CABLE" device would be the second device
on this line.

Multi–Platform Interface Feature Operation Guide 29

twinax connection

Power off

The printer's POWER switch should be in
the "OFF" position.

"Smart T" attachment

Connect the supplied "Smart T" (twinax
auto-termination cable, part number
14H5335) to the 15-pin connector on the
printer’s MPI interface. (See Figure 3 )

Termination/cable thru is automatically
accomplished by the "Smart T". The
"Smart T" has no IN or OUT specific
connectors.

Figure 3 "Smart T"

Attachment

30 Multi–Platform Interface Feature Operation Guide

Attach twinax cables

Attach the twinax cable from the host
computer to the "Smart T" connected to
the printer earlier.

1 If there is an up cable device

connected to the twinax cable (from
the host), the twinax cable must
originate from the "OUT" connector of
that device. The other end of this cable
attaches to either side of the "Smart T"
connected to the printer.

2 If this printer is the last or only device

on the twinax line, the twinax cable
attaches to either side of the "Smart T"
connected to the printer.

3 If there is a down cable device,

connect the other twinax cable to
either side of the "Smart T".

Address switch

Before testing, do the following:

twinax connection

1 Verify that the printer address matches

the one set up on your host system.
The I/O address should be unique on
the twinax line. BE CERTAIN THAT
NO ADDRESS ON THE LINE IS
DUPLICATED!!!

To set the printer address, rotate the
address switch, on the I/O, to the
number that corresponds to the
address setting for your environment.
This address should be some number
between 0 and 6.

2 Verify that the address matches the

one set up on your host system
configuration.

Multi–Platform Interface Feature Operation Guide 31

twinax connection

Power On Printer

At this point, once the cable connection
and the address settings have been
verified, you should power on the printer.

LED Indicators

The Multi-Platform Interface I/O has two
LEDs labeled SYNC and SYS (see page

75). These can be used to determine line
connection status and host
acknowledgment.

When the twinax cable is first attached to
the Smart T, the SYNC LED will light,
showing that active line connection has
been made. If the LED fails to light, the line
you are connected to may be faulty.

When the interface receives data from the
host system, the SYS LED will light
indicating a job is in progress.

32 Multi–Platform Interface Feature Operation Guide

Twinax Command Interpreter

To gain access to some features not
available on the AS/400, System 36 or
other twinax host system, a Command
Interpreter has been built into the
Multi–Platform Interface Feature.

By using special control codes, you can
pass the ASCII hexadecimal codes to the
printer that access the features of the
printer. These codes allow you to
transparently pass any character or
sequence of characters to the printer.

These codes are hexadecimal ASCII
commands and must match ones
supported by the printer and MPI ASCII
emulation selected.

The commands are initiated by use of the
logical not (¬) character. You can access
this character by pressing the Shift and 6
keys on your terminal’s keyboard.

40 Multi–Platform Interface Feature Operation Guide

Using PC Parallel with MPI

— Introduction 44
— Connection 45
— Setting time outs on the Parallel Host 46

Multi–Platform Interface Feature Operation Guide 43

Introduction

The Multi–Platform Interface Feature has
the ability to connect to two different
operating systems at once. One of these
connections is the twinax or coax
connection already discussed.

In addition, the MPI supports the use of a
Centronics** "D" connector to connect to
systems that support devices attached via a
parallel port.

When connected to two host systems, the
interface will switch to the other port once
the port currently printing is idle for a preset
period of time.

When the MPI senses data at one of its
input ports, it switches to that input port until
the print job is complete. The time between
switching from one port to the other after a
print job has finished is a user configured
parameter. This is defined by the multiplexer
timeout (See pages 6 and 7) selections:
which are short (15 seconds) or long (45
seconds).

44 Multi–Platform Interface Feature Operation Guide

Connection

Before powering on your parallel host
system, the printer cable from the system
must be plugged into the PC parallel
connector on the printer.

Select a time out configuration (either short
or long) to match your system's needs.

note

1) The printer will feed a blank page when
data host inputs are switched.

2) When switching host inputs, the printer
configuration is not preserved by the
printer's memory. Should any of your
PC or network jobs change the printer
configuration, it may be necessary for
you to reset the printer configuration.

Figure 5 PC parallel cable

Multi–Platform Interface Feature Operation Guide 45

Setting time outs on the Parallel Host

DOS

If you are using the printer attached to a
host PC system using the DOS operating
system, use the following configuration for
the retry value. The command MODE LPTn:
RETRY=P (issued from the command
prompt, or in a batch file) will set the parallel
port timeout to "infinite retry". DOS will
continue to try to print a file until it is
completed, or removed from the print queue
with a PRINT /T command.

OS/2

If you are using the interface attached to a
host PC system using the OS/2 operating
system, the retry value for the parallel port
must be set high enough to allow a host
print job to complete, plus the multiplexer
timeout value. This value is set in the
Parallel Port Setting - LPTn: screen.

Multi–Platform Interface Feature Operation Guide 47

Diagnostics

The Multi–Platform Interface Feature has its
own built-in diagnostics programs to help
you verify that the printer and the MPI are
operating properly.

Diagnostic Header

Each diagnostic test prints a header that
displays the firmware part number, revision
level, and the controller board option switch
settings. For example:

Troubleshooting your Host Printer Operation

If any problems occur while running the
Printer Verification Test in either twinax or
coax host system check the following:

1 Verify that you have assigned the

correct address setting to the printer.
(Twinax Only)

2 Verify that the address in the system

configuration matches the address
setting on the printer. (Twinax Only)

3 Verify that the device type in the system

configuration is correct for the type of
printer that is being emulated. This
emulation is set using the interface
configuration switches SW1-1 and
SW1-2. Your emulation options for
twinax mode are 4214, 4234, 5225 or

5256. In the coax operating mode, 3287
or 3262 are available.

4 Verify that the cable to the device

immediately "up cable" on the twinax
line is correctly connected. That is, if
there is an "up cable" device, does the
cable from that device originate at the
"OUT" connection. (Twinax Only)

5 Verify that the device immediately "up

cable" is functioning properly. (Twinax
only)

6 Verify that the device immediately

"down cable" is functioning properly.
(Twinax Only)

7 Verify that the I/O switch settings on the

last device on this line has been set to
the "TERM" position. (Twinax Only)

8 Verify that the printer is properly

configured (see page 10).

52 Multi–Platform Interface Feature Operation Guide

9 Verify that the Multi–Platform

Interface’s configuration switch settings
are correct (See Table 1 on page 6
(twinax) or See Table 2 on page 7
(coax)).

10Put the MPI in coax or twinax code

dump mode and print the job in
hexadecimal format. Use this printout to
verify data from the host.

11With the MPI not in code dump mode,

set the printer configuration to Hex Print
Mode and print the job. Use the printout
to verify the hexadecimal output of the
MPI going to the printer.

12With no host cable attached, the LEDs

will light briefly (about 1 second) when
the MPI has completed initialization. If
the LEDs do not do this, the MPI's
power connection may be faulty.

Compatibility Issues

The following are issues that may arise
when implementing the printer in the host
environment.

Cancel Key

When the user presses the printer's
CANCEL key, nothing is reported to the
host application. The MPI does not send a
message to the host application to cancel
the print job.

Coax PA Keys

The MPI does not have coax PA1 or PA2
device response capability.

Switching between Serial ASCII and Parallel ASCII

To switch between Serial ASCII and
Parallel ASCII, the operator must
reconfigure the printer interface selection
from the operator panel by selecting a
custom set that used the correct ASCII
interfaces. This is because the MPI
interface communicates through the
Parallel ASCII port.
