Introduction
1. Introduction
The 3270 Protocol Converter enables any Xerox laser printer to be
connected to an IBM computer system.
Printer Drivers - FSL, PCL and XES
With the 3270 Protocol Converter you have the option of selecting
between three printer drivers, the FSL, the PCL and the XES printer
driver (only up to two drivers supported at a time in any given
product).
All printer drivers may not be supported in all the products. Please
check your User’s Guide supplied with the product for the exact
printer driver(s) supported.
For selection/changing of printer driver, you are referred to your
specific User’s Guide as well.
NOTE:

3270 Programmer’s Guide
Introduction
In case the converter is equipped with a serial connector, it supports
serial input or output.
In all three printer drivers, centronics input and output is supported.
The 3270 Protocol Converter can be used with most Xerox printers.
NOTE: The printer driver must be selected before you
start the operation of the device.
1.1. FSL Printer Driver
To select the FSL printer driver, see the User’s Guide originally
supplied with your product.
This printer driver is a user specific printer driver ready for programming.
You will have to program the internal setup of the protocol converter
to suit your printing requirements. See the FSL 3270 Programmer’s
Guide, D62071 for further configuration in FSL mode.
When to use the FSL driver:
• If you need serial output from the converter to connect a printer or
other device that needs serial input.
• If you want to send printer commands directly to the printer
• If a printer without PCL4 or PCL5 emulation should be connected.
1.2. PCL Printer Driver
To select the PCL printer driver, see the User’s Guide originally
supplied with your product.
The default configuration of the converter will suffice for most
application programs and uses. You should only change the
configuration if you have special requirements.
If you should wish to change the configuration, the options may be
set from the line as described in this manual. See the PCL 3270

Introduction
• Full IBM 3268/87 and 4214 emulations including the APL feature
and all applicable RPQs (subject to restrictions of the ASCII
printers).
• Serial input or output (in case of serial connector)
• Access to all the special facilities on your Xerox printer from the
host.
• Automatic input sharing between Coax, Centronics and RS (in
case of serial connector) input.
• Coax FSL setup via Centronics.
• Support of up to 8 user strings of variable length can be transmit-
ted to the printer from the converter - automatically at power on
and before and after Local Copy from the host system.
• Up to 16 translate tables (8 for text and 8 for APL) which may be
modified as you wish. Each character from the host may be
transmitted to up to 12 ASCII characters.
• Flash PROM allowing the downloading of new firmware via the
coax or the Centronics port.
• Full backwards compatibility with existing products.
• Support of ida PSS software package
1.5. 3270 Protocol Converter Programming
The 3270 Protocol Converter uses a large number of internal setup
functions. See Chapter 2. Function Selection via the Line. When the
converter is installed and connected to a printer, you may have to
consider the use of these settings.
NOTE: (If running in FSL mode)'
The converter should be programmed to make your
decentralized printer as fully 3268/3287 compatible as
possible. This is particularly important in an SNA/LU1
environment.

3270 Programmer’s Guide
Introduction
The settings can be downloaded as special commands from your
IBM system or from a PC to the Centronics or RS 232 (in case of
serial connector) input port. The converter uses these commands for
its own internal setup.
Initially, the settings can be downloaded to the temporary memory
area (see Chapter 3. Manipulation of Temporary and Permanent
Memory Areas) of the converter, where they take immediate ef fect.
The settings in the RAM area may be saved permanently in the
permanent memory area, if specified by a special command. The
permanent memory area is read each time power is turned on to the
converter or when you give a special command.
1.6. Serial Input/Output
NOTE:
This section only applies if your product is equipped
with a serial connector
The serial port can be configured as input or output.
SERIAL OUTPUT
For serial output, the FSL printer driver has to be used.
For details on this, please see doc. no. D62071.
SERIAL INPUT
For serial input, you can use both FSL and PCL printer drivers. For
details on serial input, please refer to relevant chapters in D62071
(FSL) and D62030 (PCL) for details.

Function Selection via the Line
2. Function Selection via the Line
Function Selection via the Line (FSL) sequences are special commands used for the downloading of settings to the 3270 Protocol
Converter .
The syntax of an FSL command is shown below.
"%" is the defined escape character (i.e. ESC character). See the
section on "Escape Character" in the following.
%Y<Function number>, <parameter>%
Syntax of an FSL command
When you send the FSL syntax to the converter via the line, the "Y"
and the following number will select an FSL Function.
All spaces and IBM control codes between the leading and the trailing ESC characters will be ignored.
The FSL Functions are used for setting up the printer to special
applications, to carry out a special print job, or to gain access to
special facilities in the printer. A complete description of the supported FSL Functions for the printer drivers FSL , PCL and XES are
found in documents no. D62071, D62030 and D62067 respectively.
The Function numbers and parameters are listed as data options
along with a description of the results of selecting each option. The
parameters set the selected Function as required.
2.1. Escape Character
If you wish to program the converter, you must first define an "ESC
character "1. An ESC character is a signal to the converter that the
characters following the ESC character form a command sequence.
1
In this manual, the ESC character is synonymous with the defined escape character. Do not
confuse it with the ASCII escape control code (1B HEX).

3270 Programmer’s Guide
Function Selection via the Line
Once a character has been defined as the ESC character, it cannot
be printed or used as a normal character. However, it is not necessary to have an ESC character defined permanently. When the ESC
character has served its purpose, it can be deleted.
When you have defined an ESC character in the converter, the
following facilities will be available to you:
• Sending HEX codes (00 to FF) directly to the printer
• Changing the settings of the converter
• Sending special commands to the converter (e.g. to save the
contents of the temporary memory in the permanent memory).
When the converter receives the characters following the ESC
character, it will use them for special purposes.
Below you will find examples of FSL commands, where "%" is the
defined ESC character :
Escape Sequence Function
%Y6,100% Set Function 6: Maximum Print Posi-
tion (MPP) to 100
%Y8,04% Set Function 8, LU1 Language, to
Belgian
%Y61,1,1B,26,6C,32,58% Define user string 1 with the PCL
command "print 2 copies"
NOTE:
In FSL mode, the notations ":" and ";" have special
meanings in the FSL Functions 75 and 80. See
D62071, the section "Overwriting the Translate
Tables" for more information.
