The PSx 30 is available with a variety of options and provides a sensible choice for single-user applications requiring a PC/AT-compatible device. The Intel 80386SX CPU utilizes a 16MHz clock, 32-bit architecture and a memory capacity of up to 4MB. In addition, new firmware enhancements to the PSX 30 allow for better system support and greater overall system control. Firmware enhancements include: o Auto-sizing of memory during system startup. It is no longer necessary for a service engineer to configure the system for the amount of physical memory present. Firmware in the PSx 30 now detects how much physical memory is present, and runs memory self-tests on that amount of memory when the system is powered ON. o The SETUP utility is now stored in firmware in the PSx system board. This allows you to modify the system setup without having to insert a floppy diskette. Anytime an error is detected at startup, the system prompts you to access the SETUP program. NOTE: Only the SETUP utility exists in firmware. The diagnostics and hard disk initialization programs must still be run from floppy diskette. {w% 2.0 HARDWARE OVERVIEW The PSx 30, is composed of a main cabinet assembly, a keyboard and a monitor. The figures below show the front and rear panels of the unit. The figure on the next page shows the keyboard layout.

If your system has a 5.25" floppy drive, make sure to remove the shipping insert. NOTE: Steps 2-3 below were already done at the factory, so they are listed here for reference only. 2. AC power is set to 115V, 50/60 Hz in all units coming from the factory. If the required voltage is 230, the voltage selector switch on the power supply unit and the fuse need to be changed. A 230 volt fuse is included in the shipping packet. 3. If you have a hard disk drive, locate the bad track list label and record the cylinder and head information for future use. There is a label on the drive and also on the bottom of the main cabinet assembly. 4. Ensure that the factory-setting label is removed from the CPU-BASIC FOUR-PSx 30-------------------------------FIB002 Pg004 power inlet and that the system and monitor power cords are plugged into the wall outlet (make sure the POWER switch on the front panel is OFF). 5. Verify that the video cable is connected from the monitor to the video output connector on the back of the main cabinet assembly. 6. Make sure the front panel keyboard lock is in the unlocked position (the key is in the shipping packet). 7. Verify that the keyboard cable is plugged into the keyboard connector located on the left side of the front main cabinet assembly (below the connector for the mouse). 3.2 VERIFYING SYSTEM SETUP Since the PSx 30 is set up and tested at the factory, it should not be necessary to do this in the field. The following procedure is provided in order to verify the setup for your customer: 1. Power on the system and after the system self-test, press the , and keys simultaneously. 2. At the System Configuration Setup screen, verify that the configuration displayed agrees with your system. If it agrees, press "E" and to "END AND REBOOT", and proceed to Section 3, below. If it disagrees, go to Section 3.3 of this document for instructions to use the System Configuration Setup utility to change the setups. NOTE: The SETUP utility is also on the SYSTEM UTILITIES diskette. In addition to the SETUP utility, the utilities on the diskette allow the user to park the disk heads before moving the system and to do a low-level disk format. 3.3 CHANGING SYSTEM SETUP 1. Hold down the , and keys at the same time. Alternately, you can place the SYSTEM UTILITIES diskette in the floppy drive, select the floppy drive and run "SETUP" at the floppy drive prompt. 2. If you are running from the floppy drive, your system will display the following menu: ___________________________________________ SETUP UTILITY Version 2.2 <1> ------> SETUP CMOS RAM <2> ------> HARD DISK FORMAT <3> ------> SHIPZONE <4> ------> EXIT KEY IN OPTION NUMBER PLEASE ? _ ___________________________________________ Select SETUP: Enter "1", SETUP CMOS RAM 3.

COM1(3F8H) : DISBALE, COM2(2F8h) : DISABLE ? _ _______________________________________________________ (NOTE: Option "0" is the factory set default) If you have an add-on card with a serial port that conflicts with any serial port onboard, the system will disable the onboard function. This utility is designed so that you can select a port address that does not conflict. 3.10 ON BOARD PARALLEL PORT SELECTION You can select the parallel port address by entering 9 and to the following selection screen: _______________________________________________________ 0. SELECT LPT (IRQ 7, 378h) 1. SELECT LPT (IRQ 5, 278h) 2. SELECT LPT (IRQ 7, 3BCh) 3. DISABLED ? _ _______________________________________________________ (NOTE: Option "0" is the factory set default) If your add-on card has a parallel port that conflicts with the parallel port onboard, the system will disable the onboard function automatically. You should check the parallel port address on the add-on card and adjust the address to one that does not conflict. If you want to use both parallel ports onboard and add-on card, you can select from option 0-2 for the onboard parallel port address. Note that this address can not conflict with the add-on card. 3.11 BIOS MODE: The PSx 30 reserves 128 KB of its Random Access Memory (RAM) for the basic operating system routines (the BIOS) normally located in Read-Only Memory (ROM). You can change the BIOS location by selecting item A to choose ROM or RAM BIOS: _______________________________________________________ 0. ROM BIOS 1. SYSTEM - RAM BIOS, VGA OR EGA - ROM BIOS 2. SYSTEM - RAM BIOS, VGA OR EGA - RAM BIOS ? _ _______________________________________________________ (NOTE: Option "1" is the factory set default) Type 0 to change the BIOS location mode from RAM BIOS to ROM BIOS. This envokes the following: o The amounts of memory above 1MB is increased by 128KB CPU-BASIC FOUR-PSx 30-------------------------------FIB002 Pg009 if the memory map-out function is enabled. o The EGA or VGA RAM BIOS is disabled. Changing the system BIOS location mode from ROM BIOS to RAM BIOS results in the following: o The amounts of memory above 1MB is decreased by 128KB of the memory map-out function is enabled. o The system BIOS is moved from ROM address 0E000:0 - 0E000:7FFF to RAM BIOS address 0E000:0 ~ 0E000:7FFF. You have two choices for BIOS relocation: o Type 1 to set system BIOS in RAM BIOS, and EGA/VGA in ROM BIOS. o Type 2 to set system BIOS in RAM BIOS, and EGA/VGA in RAM BIOS. NOTE: If your system cannot accept option 2, we suggest you select option 1. This means your add-on display card can not use shadow RAM. 3.12 UPDATE ALL ITEMS To run through all the parameters, type "D". The parameters appear in order. Change values as needed; press to accept a parameter's current value. 3.13 END AND REBOOT Examine all the system configuration values. When you are satisfied that all the values are correct, write them down. Store the recorded values in a safe place. In the future, if the battery dies or the CMOS chip is damaged, you know what values to enter when you rerun SETUP. To leave SETUP, press "E" and . The new configuration parameters are stored in CMOS memory and the PSx 30 reboots. 4.0 HARDWARE CONFIGURATIONS Hardware installation and configuration is covered in detail in the PSx 30 Installation and Maintenance Manual (M8222A), Chapter 2. Please refer to this document for complete information about the assemblies in the PSx 30. Shown below is a list of the major hardware assemblies and a brief description of each. NAME DESCRIPTION _ 386SX CPU Board Intel 80386SX (16MHz) microprocessor; 80387 math co-processor (optional); 1Mb RAM (up to 4MB optional); ROM 64KB (Award 386SX ROM BIOS); CMOS RAM 128KB; Keyboard controller, Clock/Calendar with battery back-up; Dual CPU speed (16/8 MHz); Shadow BIOS ROM and Video ROM for better performance.

The jumper location on the system board is labeled JP11. There are "256" and "512" labeled on two sides of this jumper. You can choose the appropriate setting for your memory type. The PSx 30 comes with two 27256 EPROMs. WARNING: Do not reset jumper unless you replace the EPROMs with 27512. To change the jumper setting, pick up the jumper clip with your fingers. Position the clip over the two pins for the desired setting, and gently press down. Be careful not to bend the pins. 4.2 ADDITIONAL MEMORY The memory on the 80386SX board is auto-sized at system startup. Therefore, it is not necessary to configure the CPU board (by setting jumpers) for the amount of physical memory on the system. Firmware on the 80386SX board detects how much memory is present and runs memory self-tests on that amount of memory when the system is powered on. The proper Base Memory and Extended Memory parameters MUST be entered under SETUP (see Section 3.8) that corresponds to the amount of physical memory on the system. WARNING: Memory SIMMs must be installed in groups of four. Refer to the PSx User Guide (M0206A), Section 7, on how to install additional memory. 4.3 HARD DISK OPTION SETTINGS The jumpers on the interface connector are the same for both the 40MB and 100MB drives. Install the /C/D jumper and the /ACT jumpers. The /HSP and /DSP should be open. There are no switch settings on either of the drives. CPU-BASIC FOUR-PSx 30-------------------------------FIB002 Pg011 4.4 3.5" FLOPPY DISK DRIVE OPTION SETTINGS For all floppy drives, set the drive select jumper to DS2. Remove the 220/230 terminator for Drive "B" only. Configure the 360KB drive for AT compatible mode by removing the jumper 'RY' near pin 34 of the I/O connector. 4.5 DIAGNOSTICS - WINDSOR PC TECHNICIAN A service level diagnostic package is available for the PSx 30 system and can be ordered through normal spares procurement channels. The package contains diagnostic software on bootable media (3.5" or 5.25" diskettes), four different loopback connectors and complete instructions for running the tests. Order P/N: 400750-003 for 3.5" bootable media 400750-004 for 5.25" bootable media Cautions and Warnings 1. The CPU/System board test is only accessible from the certification menu. If you only want to test the CPU, you can't loop it without running all other tests. 2. Error counting only works in certification mode. In diagnostics mode, no error counts are accumulated. 3. There is no floppy alignment capability. 4. Do not write to the floppy diskettes provided with the diagnostics. They have their own special format. If they are written to they must be formatted again using the diagnostic package. 5. When prompted for memory type during memory testing, choose the option, "None of the above". 5.0 INSTALLATION Perform the following to verify that the system is working and that all components are properly connected. 1. To boot the system, you must insert the MS-DOS 3.3 diskette shipped with the system into the floppy disk drive. 2. Press the power switch on the PSx 30 front panel, and power on the peripheral devices you connected to the system. Within a matter of seconds, you should see the following messages: ______________________________________________________________ 386SX Modular BIOS Version 3.03A-1, Copyright Award Software TESTING INTERRUPT CONTROLLER #1 ...OK TESTING INTERRUPT CONTROLLER #2 ...OK TESTING CMOS BATTERY ...OK TESTING CMOS CHECKSUM ...OK SIZING SYSTEM MEMORY ...640K FOUND TESTING SYSTEM MEMORY 640 OK CHECKING UNEXPECTED INTERRUPTS AND STUCK NMI ...OK TESTING PROTECTED MODE ...OK SIZING EXPANDED MEMORY ...03456K FOUND CPU-BASIC FOUR-PSx 30-------------------------------FIB002 Pg012 TESTING MEMORY IN PROTECTED MODE ...04096K OK TESTING PROCESSOR EXCEPTION INTERRUPTS ...OK WAITING .......... shadow ram RAM BIOS ENABLED Current date is Thur 3-01-1990 Enter new date (mm-dd-yy): __ Current time is 08:00:00.00 ENTER NEW TIME: __ Microsoft(R) MS-DOS(R) Version 3.30 (C)Copyright Microsoft Corp 1981-1987 _________________________________________________________ If these messages do not appear, please refer to Section 3, Troubleshooting, of the PSx 30 User Guide. 3. At the system prompt, type in the following: A> DIR This displays a directory of files stored on the diskette you just inserted. 4. If your system has more than one floppy disk drive, insert a diskette in drive B, and type the following at the prompt: A> DIR B: This displays the directory listing of the diskette in the second drive (Drive B). 5. Verify that the hard disk drive is operable by typing: A> C: The C> prompt will appear. A 40MB disk drive contains two partitions since MS-DOS only allows a maximum partition size of 32MB. Therefore, the 40MB drive will contain logical drives C and D. A 100MB disk drive also contains two partitions. The first partition contains logical drive C. The Extended (Second) DOS partition contains logical drives D, E & F. Verify the second logical drive by typing: C> D: The D> prompt should appear. If you have a 100MB hard disk, also verify the remaining logical drives (E & F) by typing: D> E: , The E> prompt should appear. E> F: , The F> prompt should appear. CPU-BASIC FOUR-PSx 30-------------------------------FIB002 Pg013 6. To test the parallel printer connection, make sure the printer is powered on and on-line and then press the key. This instructs the system to print what's displayed on the monitor. This completes the installation check-out procedure. If you encountered any problems during this installation, please refer to Section 3, Troubleshooting, in the PSX 30 User Guide. 5.1 BOOTING FROM THE HARD DISK DRIVE The system files are on the MS-DOS 3.3 floppy diskette supplied with your system. To boot your system from the hard disk drive, you must perform the following two step procedure to copy those files from the floppy diskette to your hard disk drive, after inserting the MS-DOS 3.3 diskette into drive A. 1. From the A: prompt, type: SYS C: and press This command is used to copy special system information from the floppy disk drive to your hard disk drive. 2. Next, use the MS-DOS COPY command to copy the system files. Type: COPY *.* C: Once the files are copied, you no longer need to use the floppy disk to boot your system. Store the diskette in a safe place, and keep it as a back-up copy. 6.0 UPGRADES AND OPTIONS Since many upgrades and options are available for AT type computers, it is not possible to cover them all in this document. So, this section is limited to memory upgrades and add on printers. 6.1 PRINTER ADD-ONS "Industry Standard" PC-compatible parallel/serial printers are supported on the PSx 30. It is physically possible to have one parallel and two serial printers connected to the system, although only one printer at a time can be printing. The parallel printer is called either "LPT1" or "PRN." The serial printers can be either "COM1" or "COM2." Use the MODE command (see MS-DOS manual for complete details) to set up the operational modes for the serial printer(s) on the system. For example, use the MS-DOS MODE command to configure either of the COM ports for baud rate and protocol. At the "C>" prompt, enter: MODE COM1:2400,O,7,1 (COM1 is set to 2400 baud, odd parity, 7-bits, and 1 stop bit for either a PT-4217 or PT-4218) MODE COM2:1200,O,7,1 (COM2 is set to 1200 baud, odd parity, 7-bits, and 1 stop bit for a PT-4216) The following chart shows the MBF certified printers for the CPU-BASIC FOUR-PSx 30-------------------------------FIB002 Pg014 PSx 30 along with the "factory set baud rates" of the serial versions. All printers shown are capable of running as parallel also. Some printers are supplied with both interfaces built in. For other printers, you must select the interface type at the time of purchase.

Therefore, serial printers must be re-configured for DTR protocol. Refer to your printer manual for instructions on changing protocol. Also, the MS-DOS MODE command will direct the "LPT1" output (which is the typical default printer output port in most applications) to either "COM1" or "COM2." This allows the use of a serial printer as the standard output device instead of the typical parallel printer. At the "C>" prompt, enter: MODE LPT1:=COM1 (LPT1 output goes to COM1) or MODE LPT1:=COM2 (LPT1 output goes to COM2) It is handy to have the MODEs set automatically whenever the system is booted. This is accomplished by including the appropriate MODE commands in an "AUTOEXEC.BAT" file. Please refer to the MS-DOS manual for information about creating and using this function. 6.2 OPTION INSTALLATION CHECKLIST CPU-BASIC FOUR-PSx 30-------------------------------FIB002 Pg015 Anytime internal settings or assemblies are reconfigured, the following items should be checked before replacing the cover on the main cabinet assembly: o Record any information required for modifying SETUP. o Verify that any options moved or added are installed correctly. o Verify that all mounting screws are tightened. o Verify that all of the cables and wires connecting the option are firmly in place. o Verify that all internal option switches are set correctly for the new option. o Verify that all cables and wires are tucked down out of the way so that the cover can slide on easily. o Remove all loose screws and extraneous objects from inside the computer. 7.0 POWER REQUIREMENTS Line Voltages: 115 VAC nominal (SW selectable) 230 VAC nominal Line Frequency: 47 Hz to 60 Hz AC Input Current: 4A (Max) for 115 VAC 2.5A (Max) for 230 VAC Inrush Current: 40A (Max) Power Dissipation: 134W Line Cord Specs: 115 VAC Line Cord - 18AWG SVT NEMA 5-15P/CE22V 230 VAC Line Cord - .75mm, CEE7/VII/CEE22 8.0 GENERAL SPECIFICATIONS SYSTEM o Physical: Size: Main Cabinet Assy.

KACZOROSKI CPU-BASIC FOUR-PSx 30-------------------------------FIB007 Pg002 FIB 00008 01/10/92 *** Keyboard Cleaning and Repair *** Most of the keyboards sent back to Tustin for repair require only cleaning or minor repair, procedures which can easily be accomplished in the field. 1. Cleaning and simple repair should be attempted on ALL keyboards at the field level. This covers both "switch-type" keyboards, as well as "membrane-type". Keyboards should be repaired on-site, and where this is not possible, brought back to the office or stocking location and cleaned/repaired there. In general, the keyboards can be repaired by disassembling them, blowing-out or brushing off dust and debris, cleaning the PCBA using a foaming-type window cleaner (like aerosol Windex), brightening contact points by rubbing them with an eraser (Pink Pearl), and replacing any worn-out springs or pads Even the newer-style membrane keyboards (such as the DT4315, PSx30, etc.) usually fail because of dust or liquid contamination between the membrane layers preventing a key from making contact. Disassembling these keyboards is equally easy and the membranes can be cleaned by wiping them with a soft cloth dampened with window cleaner. 2. Several hundred keyboard repair kits were distributed throughout the field in the past. Replacement parts for these kits can be ordered through Tustin, part numbers are as follows: Parts for 7270, 4309, and 4312 keyboards. Spring, Spacebar YY013799 Spring, Print Key, Clear, Escape YY012913 Spring, All Others YY012914 Pad (foam/foil for each key) YY006594 Screws (hold PCBA to Keyboard) YY019809 3. After cleaning the keyboard and attempting simple repair, if the keyboard is still not working properly, return it to Tustin using the normal return process. 4. MM810041 (Grey 4312 keyboard) and MM810036 (Putty 4312 keyboard) are alternates for each other and should be treated as such. If you need the opposite color, take the time to switch the keycaps and enclosure rather than ordering another keyboard. (Estimated time of about 10 minutes to switch everything). 5. Effective February 1, 1991, the field will not be able to Code A the 4309 and 4312 keyboards from Tustin (P/N MM783020, MM810036, MM810041).
