FAMILY / PINOUT README FILE (FPOREAD.TXT) - Version 5.20

CUSTOM CRC DRIVER PART NUMBER CONVERSION WILL BE REQUIRED IN V5.3
Customers who operate Unisystem programmers (2500, 2900, 3900, AutoSite,
and UniSite) with custom software which uses family/pinout codes for device
selection will be affected by a change in the V5.3 update.  As of that
revision, we will no longer support the use of the family/pinout codes for
device selection; they are no longer unique and there are circumstances
in which devices can be damaged by this practice.  Custom CRC drivers will
need to be converted to use manufacturer names and part numbers (programmer
menu name) for device selection to operate with the coming version.

A conversion table file (FPO_XREF.TXT) in fixed width text format is included
on the V5.2 Device List diskette to assist you in implementing the change now.
We began notifying customers in 1992 that this would become necessary, and
published an application note on writing CRC drivers which recommended the
use of manufacturer and programmer menu name for selection in CRC-drivers.
This note can be obtained from any of the following:
          Faxback FAX   206-881-2214
          BBS           206-882-3211
          Web Site      www.data-io.com
If these methods present difficulty, please call our technical support
department at (800)247-5700.  International customers can obtain copies of the
application note from their local Data I/O representative.

THE FPO_XREF.TXT FILE
The FPO_XREF.TXT file contains a table cross-references Family / Pinout
Codes to Manufacturer and Programmer Menu Names.  The table is sorted in
ascending order by Family Code and then by Pinout Code.  Blank spaces in
either the Family or Pinout columns indicates that there are multiple entries
with the above number.  In other words, the blank space indicates that for a
given Family and Pinout Code the programmer has more than one programming
option.

The file is an ASCII text file and can be viewed using an editor that can
read ASCII text files.  Due to the number of lines in the file, the DOS
editor, "edit", may have troubles reading the file.  Thus, one may want to
use an editor like Microsoft Word to view the file.  If an alternative editor
is not available, the file can be viewed using the utility "LST.COM" that is
also available on the Device List diskette.  If both the "LST.COM" file and
the "FPO_XREF.TXT" file are in the same directory, the user can type the
following at the DOS prompt:
         prompt> lst fpo_xref.txt

If the user has a custom Computer Remote Control (CRC) driver for one of the
Unisystem programmers, the user will need to replace the method of selection
of a device from Family / Pinout Code to Manufacturer and Programmer Menu
Name.

SELECTION OF A DEVICE BY FAMILY / PINOUT CODE
*** This selection capability is being obsoleted in V5.3. ***
The selection of a device using Family / Pinout Code is accomplished using the
following CRC command:
          "FAMPIN@" (or "AMIN@")
    where "FAM" is the 3 digit Family Code ("AM" can be used if the first
                digit of the 3 digit code is zero); and
          "PIN" is the 3 digit Pinout Code ("IN" can be used if the first
                digit of the 3 digit code is zero).

SELECTION OF A DEVICE BY MANUFACTURER AND PROGRAMMER MENU NAME
The selection of a device using the Manufacturer and Programmer Menu Name is
accomplished using the following 2 commands:
                 Manufacturer33]
           ProgrammerMenuName34]
    where "Manufacturer"       is the name of the Manufacturer of the
                               device from the FPO_XREF.TXT file; and
          "ProgrammerMenuName" is the programmer menu name from the
                               FPO_XREF.TXT file and is the same menu name
                               that appears when using the programmer in
                               terminal mode.
There must NOT be a space between the Manufacturer or ProgrammerMenuName and
the command indicator, "33]" and "34]", respectively.  The Manufacturer
command must immediately be followed by the Programmer Menu Name.
