passive backplane, slide-out "work drawer" card cage, 250-watt power  
supply, 3½" floppy disk drive (slim CD-ROM and 3½" HDD optional),  
front and rear 5-pin keyboard connectors and a sealed front panel that  
conforms to NEMA 4 and NEMA 12 specifications. All of these features  
are housed in a rugged workstation chassis which provides protection  
from dust, vibration and moisture.  
14.1" Color LCD  
• Vertical and flat screen for better display quality  
• High resolution display (1024 x 768)  
• Anti-static treatment on the glass surface to minimize dust accumula-  
tion on the monitor  
• Digital screen adjustment for accurate picture quality  
39-key sealed-membrane operating keypad  
You can enter numerical data using the workstation's convenient 39-key  
sealed-membrane operating keypad. The keypad has excellent tactile  
response. You can also attach an external keyboard through a connector  
on the front panel.  
Programmable macro function keys  
An additional membrane keypad offers 10 ordinary function keys (F1 ~  
F10) and 10 programmable macro keys (SF1 ~ SF10). Macro keys auto-  
mate common key sequences, even inside application programs.

Passive backplanes  
The AWS-8248 offers two types of passive backplanes, the PCA-6108C  
and the PCA-6107P2. They allow you to run your industrial applications  
from a variety of full-featured CPU cards.  
Figure 1.1: The PCA-6108C and PCA-6107P2 passive backplanes  
The backplanes are formed from four-layer PCBs with ground and power  
planes to reduce noise and power-supply impedance. They have LED  
power indicators for +5 V, +12 V, -5 V and -12 V.  
Advantech's PCA-6107P2 passive backplane can be installed into the  
AWS-8248TP. It contains two PCI-compatible slots, four PC/AT-compat-  
ible (ISA-bus) slots and one dedicated slot for a CPU card. Three power-  
connectors are also included in the PCA-6107P2.  
Alternatively, Advantech's PCA-6108C passive backplane can be  
installed into the AWS-8248T. It contains eight PC/AT-compatible (ISA-  
bus) slots, termination resistors for high-speed signals and terminal block  
connectors to supply power from the board.  
Convenient work drawer  
The AWS-8248's "work drawer" card cage slides out in a snap for  
reduced MTTR. It makes adding or exchanging plug-in cards and chang-  
ing power supplies quick and easy. Our standard PC/AT compatible pas-  
sive backplane lets you run your industrial applications from a variety of  
full-featured CPU cards. and easy overclocking of frequency and Vcore  
voltages all through the BIOS Specifications.

3.7 Membrane keypad  
This eventually wears out after exhaustive and prolonged use. The metal  
dome switches lose their elasticity, the contact surfaces wear down, and  
chemical corrosion sets in. The membrane keypad film can become torn.  
If more than, say, three metal domes are broken, this may indicate that the  
keypad tail series is broken, or that the single cable connecting the keypad  
tail is defective.  
Replacing the membrane keypad is now easier than before. You must,  
however, slide out the work drawer.  
To replace the operating membrane keypad:  
1.  
2.  
Switch off the power, and detach the main power cord.  
Detach the work drawer and cover from the AWS-8248 unit. (See  
Fig. 2-1.)

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].

SFED8248.COM with EXAMPLE.TXT.  
SF2 = COPY C:\CONFIG.EMM C:\CONFlG.SYS [33] Y [33] [85]  
[79]  
The configuration information is changed by copying CONFIG.EMM to  
CONFIG.SYS. After a delay of 5 seconds, [85], the macro invokes macro  
function key SF10, [79], which was defined to reset the system.  
SF4 = C:\WP51\WP[33][86][27][4D][90]REPORT.WP5[33]  
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.  
SF10 = [28][26][41][90]  
Restarts the computer (CTRL-ALT-DEL).

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.

Power good signal:  
When the power is turned on, the power good signal will activate 100 to  
500 ms after all output DC voltages are operating within their respective  
regulation limits.  
Power fail signal:  
This will activate at least 0.5 ms before any of the output voltages fall  
below their respective regulation limits.

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.
