CHAPTER 2 System Setup • General • Opening the Rear Panel • Adding cards • Installing Hold-down Clamps • Installing optional drives • Connecting cables • Connecting External Keyboard and Mouse • Rack/Panel/Wall mounting Chapter 2 AWS-8259 System Setup 11
2.1 Integration system setup The WS-8259 offers two ways to meet the requirements of industrial computing platforms, integrated or separated applications. For integrated application,the AWS-8259 can be used as a complete computing platform.It supports a 9 ISA/PCI slot,15"TFT LCD workstation. For separated applications,the WS-8259 can be separated into a LCD monitor and control chassis. 2.1.1 General The AWS-8259 adopts a standard industrial PCI/ISA backplane.
2.1.2 Opening the Rear Panel Unscrew the two knobs in the rear panel and open the back cover (see Fig. 2-1). The back cover is "hinged" to the chassis. If necessary, unplug the power cord of the fan to remove the rear door.
2.1.3 Adding Cards The PCI passive backplane accepts both PCI-bus and ISA-bus CPU and I/O cards. We recommend all-in-one cards. They are durable, and save valuable slot space by bundling a CPU card with hard disk and floppy disk controllers, as well as serial and parallel ports. Open the rear door (see Fig. 2-2) and then slowly slide the card in and carefully press it into the backplane socket. Secure it with a screw to the side-mounting bar. Connect the wires. Install additional cards as needed.
Figure 2-3: Card Installation Note 2.1.4 Installing Hold-down Clamps After installing the cards on the backplane, you may want to affix holddown clamps to secure the cards better. Take the several round rubber pads and clamps from the accessory box. Choose a suitable position on the clamp shelf whereby the card can be firmly secured. Put the round rubber pads in the holes with the clamps. (see Fig. 2-4). Then insert the clamp and screw it in the chassis.
Figure 2-4: Installing Hold-down clamp 2.1.5 Installing Optional Disk Drives The AWS-8259 provides space for the drives (one 3.5" floppy disk drive, two 3.5" hard disk drives and one slim CD-ROM drive) underneath the case. A front-facing floppy drive has already been installed. You can access it from the FDD dust-resistant door panel. A slim CD-ROM and HDD unit can be installed in the bottom of the chassis.

Figure 2-7: Installing floppy 18 AWS-8259 User's Manual
2.1.6 Connecting Cables After inserting the CPU card into the chassis, connect the FDD, CDROM and HDD cables to the CPU card. In addition to the storage devices, four other cables need to be connected: the PS/2 touch pad cable, VGA cable, USB/Ind./Power cable and RS-232 cable for the touch screen. The PS/2 mouse cable is used to connect the touch pad signal output from the front panel to the CPU card, as shown below. There is a keyboard control board in the system that integrates the keyboard signals.
Connect PS/2 Touchpad/Keyboard cable to CPU card Connect VGA cable to CPU card Figure 2-8: Connecting cables 20 AWS-8259 User's Manual
2.1.7 Connecting External Keyboard and Mouse You can connect an external keyboard to the workstation. The connection to the keyboard is the PS/2 connector on the front panel, under the dust-protection door. Please note that you CANNOT connect a mouse to the PS/2 connector on the front panel. There are two additional keyboard connectors on the back of the chassis as shown in figure 2-10. You cannot connect two keyboards to these two connectors on the back at the same time.
2.1.8 Panel Mounting The AWS-8259 can be installed on a shelf or table, or mounted within a panel. Dimensions for the case, the mounting flanges, and the mounting bolts are shown in Fig. 2-11. Once you have added your cards, drives, and other equipment, you can switch on the AWS-8259 to check if it operates properly. Then the case can be set within your panel aperture so that your screw holes line up with the mounting bolts on the flanges of the AWS-8259. Finally, secure the bolts to the panel.
2.1.9 Rack Mounting The AWS-8259 can also be mounted in a 19" rack. Make sure that all additional equipment has been installed correctly. Also, make sure that all cabling (such as the monitor signal cable, the keyboard cable and the monitor power cable) have been reattached. Fit the rack into the case by using screws on both sides of the case.

CHAPTER 3 Macro Key Programming • Introduction • Macro Components • Syntax • How to Use SFED8259 COM • Examples Chapter 3 AWS-8259 Macro Key Programming 25
3.1 Introduction Our workstations are equipped with programmable function keys (macro keys) that greatly enhance the operator interface. Macros, far more powerful than batch files, automate the most commonly used input sequences. They extended their functional reach to within application programs. 3.2 Macro Components The following article explains how to use and program the function keys.
3.3 Syntax Macro definitions consist of ASCII characters or character codes for special characters such as ALT, ENTER, SHIFT, F1, SF2, and so on. These codes are predefined, and SFED8259.COM will display them on the screen for you. They are easily recognizable, appearing between the square brackets ‘[‘ and ‘]’. For example: ALT represents [26] ENTER represents [33] In your macro script, you can enter ordinary text (ASCII characters) or the code(s) of the required special character(s).
For example: ALT-F1 represents [26][44][90] CRTL-C represents [28]C[90] SHIFT-B represents [27]B[90] Please refer to the following examples: ALT-X represents [26]X[90] or [26]x[90]. ALT-F1 represents [26][44][90] SHIFT-X represents [27]X[90] SHIFT-F1 represents [27][44][90] CTRL-X represents [28]X[90] CTRL-F represents [28][44][90] CTRL-ALT-DEL represents [28][26][41][90] (reboot) CTRL-ALT-A represents [28][26]A[90] CTRL-SHIFT-1 represents [28][27]1[90] Another useful function is the DELAY instruction.
3.4 How To Use SFED8259 COM First, boot your system under pure DOS mode (not DOS shell in windows) 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 SFED8259 NEWKEY.TXT [ENTER]. Note: SFED8259.COM could only work properly under pure DOS mode.
When you have finished editing, press the ESC key. At the bottom line of the screen you will be prompted to choose if you want to save the file and/or if you want to transmit it to the EEPROM. After confirmation with the ENTER key, the tasks are carried out and you return to DOS. 3.5 Examples We will explain all macro functions that you can find in the EX8259.TXT macro script file. After typing SFED8259 EX8259.
SF1 = CD\TOOL[33] SFED8259 EXAMPLE.TXT[33] This macro changes to the TOOL directory, then starts up SFED8259.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.
