     The V5.20 Device List diskette for each programmer contained

     the programmer associated file with the name FPO_XREF.TXT.



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.
