Chapter 4 Macro Key Programming
4.1 Introduction
Our workstations are equipped with programmable function keys (macro
keys) that greatly enhance the operator interface. Macros, which are far
more powerful than batch files, automate the most commonly used input
sequences. They extended their functional reach to within application
programs.
4.2 Macro Key Review
The complete macro function consists of the following elements:
Macro keys (SF1 , SF2, ... SF10)
Ten programmable macro keys that are located on the dust-proof door on
the front panel of your workstation.
Macro EEPROM
Holds the key sequences that are activated when the corresponding macro
key is pushed.
Macro programming utility
In the sub-directory, AWS-8259&8124&8248/KBT-utility, of the HMI
utility CD-ROM, you will find a program called SFED8248.COM.. The
SFED8248 program provides an edit function to produce an ASCII file
that contains key stroke sequences for every macro key. After you have
finished editing the file, the program will ask you whether you want to
save the macro script and/or transmit it to the EEPROM. Macros consist
of keystroke sequences to automate the most common procedures in your
application. The way they function is much like batch files (.BAT) under
DOS, but there are some differences. In a Macro, you have to specify the
ENTER key explicitly. Also, macros give you the option of entering key
sequences in an application that was executed by the macro itself.

4.3 Syntax
Macro definitions consist of ASCII characters or character codes for spe-
cial characters (ALT, ENTER, SHIFT, F1, SF2, and so on). These codes
are predefined, and SFED8248.COM will display them on the screen for
you. They are easily recognizable,
appearing between the square brackets, "[" and "]".
For example:
ALT is represented by [26]
ENTER is represented by [33]
In your macro script, you can enter ordinary text (ASCII characters) or
the code(s) of the required special character(s).
For example:
CD\TOOLKIT[33] means CD\TOOLKIT [ENTER]
For combination keystrokes (ALT/SHIFT/CTRL + another key) enter the
codes of the special characters, followed by [90]
(RELEASE).

For example:
ALT-F1 is represented by [26][44][90]
CRTL-C is represented by [28]C[90]
SHIFT-B is represented by [27]B[90]
ALT-X is represented by [26]X[90] or [26]x[90]
ALT-F1 is represented by [26][44][90]
SHIFT-X is represented by [27]X[90]
SHIFT-F1 is represented by [27][44][90]
CTRL-X is represented by [28]X[90]
CTRL-F is represented by [28][44][90]
CTRL-ALT-DEL is represented by [28][26][41][90] (reboot)
CTRL-ALT-A is represented by [28][26]A[90]
CTRL-SHIFT-1 is represented by [28][27]1[90]
Another useful function is the DELAY instruction. You can instruct the
macro program to wait before executing the next keystroke.
SFED8248.COM displays the codes that you can use for various delays.
For example:
[86] - wait for 10 seconds before executing next keystroke
[88] - wait for 1 minute before executing next keystroke
[26]A[90][86][26]B[90] means ALT-A, wait 10 seconds, ALT-B

4.4 How to use SFED8248.COM
First, boot your system under pure DOS mode (not DOS shell in win-
dows) and copy all the files to your hard disk and/or make a backup disk.
Then start the macro editor. You will have to specify either an existing
macro script file or a new macro script file. Here we will create a new file
by typing SFED8248 NEWKEY.TXT [ENTER].

This example shows that after a macro executes, it is able to direct the
program to accomplish several tasks. WordPerfect is started. After a delay
of 10 seconds (time to load the program), the
command Shift-F10, [27][4D], is issued to import a text file. The name of
the text file (REPORT.WP5) is inserted; and finally ENTER, [33], causes
the text file to be loaded and displayed on the screen.

At the factory, the +5 V output was set between 5.00 and 5.10 V, while
other outputs were simultaneously set at 60% of their respective rated
loads.
The -5 V and -12 V outputs can be used at their respective rated loads.
The +5 V output should carry a load of at least 4 A.
Output power:
Total DC continuous power does not exceed 250 W. Each output should
be able to operate continuously under its maximum load.
Ripple and noise:
Peak to peak ripple and noise for each output is less than 1% of
each output’s respective voltage. Measurements were performed
with a 15 MHz bandwidth limited oscilloscope, and each output
was terminated with a 0.47 µF capacitor. V

Line regulation:
The output line regulation for each output is less than 1%, when mea-
sured at each output’s respective rated load and under 10% changing
input voltage conditions.
Load regulation:
The values for each of the following output numbers were obtained by
changing each output load 40% from the 60% rated load, whilst simulta-
neously keeping all other outputs at 60% of their respective rated loads.

General features
Efficiency:
65% typical when measured at nominal input and rated load.
Input protection:
Protection against wrong polarity if the +24 V input voltage is mistakenly
reversed.
Output protection:
If for some reason the power supply fails to control itself, the built-in
over-voltage protection circuit will shut down the outputs to prevent dam-
age to external circuits. The trip point of the
crowbar circuit is approximately 5.7 ~ 7.0 V. The power supply will go
into hiccup mode under short circuit or overload
conditions, and will recover automatically when such conditions cease to
exist.
