1)  QUICK START GUIDE AND IMPORTANT NOTES FOR EXPDD

OPERATION FROM THE HARD DRIVE:

1.      Change your config.sys file so that it has the lines:

			FILES=30
			BUFFERS=30

	The program will NOT run properly if your files and buffers are not 
	at least 30.

2.      Make a directory for EXPDD.
	a.      At the "C:\>" prompt, type "MD EXPDD"
		This will create a directory for EXPDD on the hard drive.

3.      Type "CD \EXPDD"
	This will change the directory from the root directory to the directory 
	for EXPDD.  The prompt will change to "C:\EXPDD>".

4.      Put disk 1 into drive A:

5.      Type "COPY A:*.* "
	This will copy all of the files from disk 1 to the EXPDD directory on 
	the hard drive.

6.      When this is complete, replace disk 1 with disk 2 and repeat step 5.

7.      Type "PDD" to start EXPDD.


OPERATION FROM THE DISK DRIVE:

1.      Put disk 1 into drive A:

2.      Type "PDD"


HARDWARE CONNECTIONS:

1.      Locate the RS232 to Current Loop Converter (For EX100/200/250/500 
	or M20/40 only).  Part #EX25GP232A-TIC2

2.      Attach one end of the converter into COM1 or COM2.

3.      Attach the other end of the converter to the programming port on 
	your PLC.

4.      If you have an EX100 with an enhanced CPU, make sure the PROGRM/LINK 
	switch on the front of the CPU is in the PROGRM position.

5.      Plug the sentinel key into your parallel printer port.  You can then 
	connect your printer on the back side of the key.


RS232 to RS422 CONVERTER (COM 1 to Computer Link Port)

The connections for the newer converters are different from the connections 
that are give in the EXPDD manual and the EXPDD software's help screens.  
This new converter does not require an external power supply.  It gets its 
power from the comm port for short distances.  The unit has been tested by 
the manufacturer at 19.2 Kbaud at 4000 feet without a power supply.

			    Connections:
	RS232-RS422                     PLC
	
	TD(A)   ----------------------->        RXB
	TD(B)   ----------------------->        RXA
	RD(A)   <-----------------------        TXB
	RD(B)   <-----------------------        TXA     


MISCELLANEOUS:

This version of the software uses a 3.5" disk drive.  If you do not have access 
to one, then contact your distributor to obtain a copy on 5.25" disks.

If you are using PDD250-V2 (PDD for the EX100, M20/40) then there is a new 
feature in the documentation screen.  There is an option for selecting 
different kinds of printers.  There are selections for an HP Laser printer, 
IBM/Epson, plain graphics, and plain ASCII.  The plain graphics requires 
manually setting up your printer for the IBM enhanced graphics character set.

2)  INSTRUCTIONS FOR DOWNLOADING SOFTWARE UPDATES BY MODEM

You can obtain EXPDD software by using your modem to contact the Toshiba 
America Computer Bulletin Board.  The phone number is 714-837-4408.  Baud 
rates are 300 to 9600 baud.  No parity, 8 data bits, 1 stop bit.

Below are instructions for downloading the software.  Things which you type 
are in bold.

You will be asked your name, phone number, and also asked to make up a password.  
You will have to enter the communication protocol that you intend to use for 
downloading.  Then you will be subjected to page after page of advertisements 
for Toshiba products.  To avoid viewing all of these, type N and hit Enter 
when it says "MORE?"  A menu will appear now.

(L)ocate File By Name      L

Enter filename to search for.      PD*.*

You should now see a list of updates for the software.  The filenames will 
all start with "PD".  Look at the dates to find the most recent one.  Typically, 
updates come out every several months.  

Return to the main menu, and choose (D)ownload a File.  Just type D and hit 
enter.  Then type in the filename.  The filenames will be "PDD250V2.ZIP" and 
"PDD2040.ZIP".

Now the bulletin board is ready to download the file to you.  The file is 
Zipped, so you will need PKUNZIP.  This program is on the board if you don't 
have it.  Make sure that you are you using the newest version of PKUNZIP.  
The complete package is included in each ZIP file, so it takes a while to 
download.  At 2400 baud, it takes about 30 minutes to download each file.

3)  HOW TO OBTAIN HELP PROGRAMMING YOUR TOSHIBA PLC:

1)     The EX100 users manual. This has a detailed explaination of each EX100
       instruction and each input / output module.  The list price of the
       manual is $25, and the part number is UM-EX100-E001. 

2)     The Hand Held Programmer (HP100) manual.  This gives good information on
       using the Hand Held Programmer, and also help with setting up the input/
       output allocation. List price is $25, and the part number is 
       UM-EX25UB-E022.

3)     The PLC Primer:  This book written exclusively for the Toshiba PLC and 
       walks the user through programming the software.  It focuses on using the
       EXPDD programming software.  We strongly recommend the people new to the
       Toshiba PLC's purchase this.  There are two versions of the book, 
       depending on which PLC you have purchased.  Price is approximately $35.  
       The author, ED DROPKA, can be reached at 903-364-2365.

*****************************************************************************
  
4)   COMMON PROBLEMS:  

	I get "OUT OF MEMORY" or "INSUFFICIENT FILE HANDLES" or similiar errors
	while running the software.  Solution:  Make sure that your files and
	buffers are each set for at least 30.  Also, type "mem" at the "C:\"
	prompt, and make sure that your "largest executable program size" is
	at least 550 Kb.

	When I try to save a page of ladder logic, I get an "INVALID REFERENCE
	NUMBER" error.  Solution:  A valid I/O allocation MUST be entered 
	before the software will work properly.  The easiest way to set this
	up is to go to the I/O Allocation Setup screen, and run the auto I/O 
	setup.  See your EX100, M20, or HP100 manual for more information on
	this.
  
	MY PROGRAM DISAPPEARS when I turn off my EX100 or M20/40.  Solution:  
	You need to write the program to the internal EEPROM before turning off
	the power.  On power-up, the program stored in the EEPROM is written to
	the RAM.  
  
	The error "NO END STATEMENT" appears when I try to run the program.
	Solution:  Put an END statement at the end of the program.

*******************************************************************************
5)  IMPORTANT KEY DEFINITIONS

	There are a few keystroke combinations that are important to know:

	The "SHIFT" key combined with a function key executes the command on
	the top half of the softkey.

	"Ctrl" and "PgUp" pressed together allows you to scroll up in the 
	program monitor mode.  Similiarly, "Ctrl" and "PgDn" scrolls down in 
	the program monitor mode.

	"Ctrl" and "End" pressed together while in the program mode will 
	display the last page of ladder logic.  And "Ctrl" and "Home" will
	bring up the first page of the program.

*******************************************************************************
