Xerox FS 3270 用户手册

This chapter gives you a short description of the  Xerox FS 3270  and its
installation requirements.

The Xerox FS 3270 is a protocol converter which enables any printer (or
other output device) to be connected to an IBM computer sys tem.

The printer or device should have either an  RS 232/V24 serial connector,
or a Centronics parallel connector in order to be con nected to the Xerox
FS 3270  protocol converter.

The IBM system should use the  3270 type terminals. See  Section 1.3,
Supported Control Units, for information on the IBM systems to which the
Xerox FS 3270  connects.

The output driver selection switch on the rear panel of the box al lows you
to change from PCL (factory default) to FSL if needed:

The PCL Driver (Default Driver)
If you wish to operate in  PCL mode, the box is ready to operate as it is
when delivered.  It is important that you do not change the position of the
switch. When used with certain older IBM controllers, the FSL function Y8
may have to be set to obtain the correct SCS printer language. For further
programming of the box, you are referred to the Laser 3270 Programmer's
Guide; D62078, subpart D62030.

The FSL Driver
To use a non-PCL printer or connect to a serial input port on a printer, you
have to set the switch to  FSL/alternate. For this, you must follow the
instructions in the section “Changing the Printer Driver”. The Xerox FS
3270   box is compatible with the Xerox 3270 box. For program ming the
internal setup of the box you must refer to the Laser 3270 Programmer's
Guide; document no. D62078, subpart D62071.
