PC-510 user’s manual Notice to user

IMPORTANT!

Please read the following section before installing your product:

Octagon’s products are designed to be high in performance while consuming very little power. In order to maintain this advantage, CMOS circuitry is used.

CMOS chips have specific needs and some special requirements that the user must be aware of. Read the following to help avoid damage to your card from the use of CMOS chips.

≡≡

≡ Using CMOS circuitry in industrial control

≡≡

Industrial computers originally used LSTTL circuits. Because many PC components are used in laptop computers, IC manufacturers are exclusively using CMOS technology. Both TTL and CMOS have failure mechanisms, but they are different. Described below are some of the failures which are common to all manufacturers of CMOS equipment. However, much of the information has been put in the context of the Micro PC.

Octagon has developed a reliable database of customer-induced, field failures. The average MTBF of Micro PC cards exceeds 11 years, yet there are failures. Most failures have been identified as customerinduced, but there is a small percentage that cannot be identified. As expected, virtually all the failures occur when bringing up the first system. On subsequent systems, the failure rate drops dramatically.

n Approximately 20% of the returned cards are problem-free. These

cards, typically, have the wrong jumper settings or the customer has problems with the software. This causes frustration for the customer and incurs a testing charge from Octagon.

n Of the remaining 80% of the cards, 90% of these cards fail due to

customer misuse and accident. Customers often cannot pinpoint the cause of the misuse.

n Therefore, 72% of the returned cards are damaged through some

type of misuse. Of the remaining 8%, Octagon is unable to determine the cause of the failure and repairs these cards at no charge if they are under warranty.

Notice to user PC-510 user’s manual

The most common failures on CPU cards are over voltage of the power supply, static discharge, and damage to the serial and parallel ports. On expansion cards, the most common failures are static discharge, over voltage of inputs, over current of outputs, and misuse of the CMOS circuitry with regards to power supply sequencing. In the case of the video cards, the most common failure is to miswire the card to the flat panel display. Miswiring can damage both the card and an expensive display.

n Multiple component failures - The chance of a random compo-

nent failure is very rare since the average MTBF of an Octagon card is greater than 11 years. In a 7 year study, Octagon has found a single case where multiple IC failures were

never

not caused by misuse or accident. It is very probable that multiple component failures indicate that they were user-induced.

n Testing “dead” cards - For a card that is “completely nonfunc-

tional”, there is a simple test to determine accidental over voltage, reverse voltage or other “forced” current situations. Unplug the card from the bus and remove all cables. Using an ordinary digital ohmmeter on the 2,000 ohm scale, measure the resistance between power and ground. Record this number. Reverse the ohmmeter leads and measure the resistance again. If the ratio of the resistances is 2:1 or greater, fault conditions most likely have occurred. A common cause is miswiring the power supply.

n Improper power causes catastrophic failure - If a card has had

reverse polarity or high voltage applied, replacing a failed component is not an adequate fix. Other components probably have been partially damaged or a failure mechanism has been induced. Therefore, a failure will probably occur in the future. For such cards, Octagon highly recommends that these cards be replaced.

n Other over-voltage symptoms - In over-voltage situations, the

programmable logic devices, EPROMs and CPU chips, usually fail in this order. The failed device may be hot to the touch. It is usually the case that only one IC will be overheated at a time.

n Power sequencing - The major failure of I/O chips is caused by the

external application of input voltage while the Micro PC power is off. If you apply 5V to the input of a TTL chip with the power off, nothing will happen. Applying a 5V input to a CMOS card will cause the current to flow through the input and out the 5V power pin. This current attempts to power up the card. Most inputs are rated at 25 mA maximum. When this is exceeded, the chip may be damaged.

n Failure on powerup - Even when there is not enough current to

destroy an input described above, the chip may be destroyed when the power to the card is applied. This is due to the fact that the input current biases the IC so that it acts as a forward biased diode on powerup. This type of failure is typical on serial interface chips.

PC-510 user’s manual Notice to user

n Hot insertion - Plugging cards into the card cage with the power on

will usually not cause a problem. (Octagon urges that you do not do this!) However, the card may be damaged if the right sequence of pins contacts as the card is pushed into the socket. This usually damages bus driver chips and they may become hot when the power is applied. This is one of the most common failures of expansion cards.

n Terminated backplanes - Some customers try to use Micro PC

cards in backplanes that have resistor/capacitor termination networks. CMOS cards cannot be used with termination networks. Generally, the cards will function erratically or the bus drivers may fail due to excessive output currents.

n Excessive signal lead lengths - Another source of failure that was

identified years ago at Octagon was excessive lead lengths on digital inputs. Long leads act as an antenna to pick up noise. They can also act as unterminated transmission lines. When 5V is switch onto a line, it creates a transient waveform. Octagon has seen submicrosecond pulses of 8V or more. The solution is to place a capacitor, for example 0.1 µF, across the switch contact. This will also eliminate radio frequency and other high frequency pickup.

≡≡

≡ Avoiding physical damage to the heatsink/CPU

≡≡

WARNING! When handling any Octagon CPU card, extreme care must be taken not to strike the heatsink against another object, such as a table edge. Also, be careful not to drop the CPU card, since this may cause damage to the heatsink/CPU as well.

Epoxy adhesive bonds the heatsink to the CPU chip. When the heatsink is struck, the epoxy adhesive does not allow the heatsink to separate from the chip. The force of the blow to the heatsink then causes the legs of the CPU chip to separate from the PCB. This force damages both the CPU chip and the PCB.

Note Any physical damage to the CPU control card is not covered under

warranty.

≡ Description

The PC-510 Mobile Industrial Computer™ (MIC) is a high performance, single board PC in Octagon’s semi-custom product line. The PC-510 integrates serial communication, industrial digital I/O, a floppy and a hard disk port, a multifunctional parallel port, and a local bus video which supports monitors and flat panels. It has an interrupt routing matrix, two solid-state disks, and a PC/104 interface. The PC-510 can have up to 16 MB of on-board DRAM. This board is supplied with DOS

6.22 in ROM but will also execute other operating systems such as Windows™, Windows NT™, and QNX same functional blocks as the Micro PC™, the circuitry has been fully proven as reliable and the software is compatible with the software in the Micro PC series.

Specified to your engineering needs, the PC-510 can be ordered as a semi-custom board in OEM quantities. The stocked version of the PC-510 is listed below with the standard and optional features. The standard version can be used for system development and an optional version of the PC-510 is usually application specific.

Overview

. Since the PC-510 uses the

≡ PC-510 major hardware features

CPU

The high performance 586 CPU comes in two versions. One version is a 120MHz586 and the other is a 133MHz586. Both versions operate at

3.3V for low power consumption. The PC-510 has a local bus speed of 33 MHz and an ISA bus speed of 8.33 MHz.

Up to 48 MB DRAM

The standard unit is supplied with 1 MB of fast, EDO surface mount DRAM. The use of EDO DRAM increases performance by 20% which, in most cases, eliminates the need for an expensive L2 cache. The PC-510 can contain up to 16 MB of on-board DRAM. Up to 32 MB of additional DRAM can be added through an optional DIMM module, which makes a total of 48 MB DRAM. Two holes are on-board the PC-510 to secure the DIMM module in high vibration environments. All surface mount DRAM and DIMM modules from Octagon meet the full PC-510 temperature range. Customers who need a 0° to 70°C range can install commercially available DIMM modules onto the PC-510.

Solid-state disks

SSD0

A 32-pin DIP socket accepts either a 5V flash, SRAM, or 512 KB/1 MB EPROM. To use an optional 512 KB SRAM, the PC-510 requires a factory change. The socket exhibits high retention force and affords a gas tight contact. SSD0 optionally contains the BIOS drive and ROMDOS 6.22 in ROM. By default, the optional SSD0 reserves 192 KB for BIOS and 320 KB for a drive area. Flash file system software is included which allows the SSDs to emulate hard disk operation. SSD0 options include:

n SSD0 socket installed standard n SSD0 socket not installed optional n SSD0 socket/EPROM installed optional n SSD0 support from SRAM optional

For information on changing the device type, refer to the W5 SSD0 table in the Quick start chapter. You can also install compatible PROMs into SSD0 through the supplied utility programs found on the PC-510 utility disk. You can format the flash or SRAM while in the socket. EPROM usage, however, requires off-card programming from either a master flash or a master SRAM.

SSD1

SSD1 is used for storage of the applications program. A standard 2 MB 5V flash is soldered on-card. The flash programmer is built-in which allows on-card programming of the device. The PC-510 includes flash file system software, which permits the SSDs to emulate hard disk operation. Automatic “wear leveling” ensures that no single section of a chip will reach its life span (100,000 times), while other sections will scarcely be used. A 1 MB device reserves 192 KB for BIOS and 832 KB for a drive area, a 2 MB device reserves 192 KB for BIOS and 1856 KB for a drive area.

— Contact discharge ±6 kV — Air-gap discharge ±8 kV

n Backdrive protection n 16C550 compatible n Up to 115.2K baud n 16 byte FIFO buffers n RS-232 voltages generated on-card n COM1 through COM6 standard n Omission of COM3 through COM6 optional

Local bus SV GA, flat panel interface, and GUI accelerator

The video system on the PC-510 uses the advanced 65550 video chip from Chips & Technologies. It supports CRT, LCD and EL displays with resolutions to 1280 x 1024 bpp. Displays from CGA through SVGA are supported. The 65550 is also a graphics accelerator with real time PC-video being supported. Since the video circuitry operates on the local bus at the full processor speed, programs like Windows execute very rapidly. The video section has 2 MB of video RAM for high resolution displays and simultaneous CRT and flat panel operation. The PC-510 also supports 5V and newer generation displays, which use

3.3V.

n Local bus flat panel video present standard n No local bus flat panel video present optional

Adjustable display bias supply

An on-board voltage converter eliminates the need for a separate bias supply for the LCD contrast control. The on-board power converter is factory configurable and can be made to be compatible with most LCD displays. The standard default range for the power converter is from +23V to +29V.

PC/104 16-bit interface

This interface is a standard feature on the PC-510 and accepts an 8- or a 16-bit PC/104 expansion board. PC/104 expansion boards are available from several manufacturers. As many as three PC/104 expansion boards may be stacked on the PC-510.

≡ PC-510 major software features

Advanced po wer management and system management input

1-4

Power management can be used to reduce power consumption or to freeze the state of the program on the occurrence of a power management interrupt. Power consumption can be reduced by more than 60%. This reduces the heat load and extends the battery life in mobile applications. There are opto-isolated system management and suspend/ resume inputs with 4-6V ranges. A system management input (SMI) will cause the PC-510 to save its current status. When the system is

PC-510 user’s manual Overview

signaled to restart, execution resumes at the point the system last stopped. The following are functions in the advanced power management and SMI:

n Suspend/resume by SMI input and software — halts CPU n Wake up through various interrupts including keyboard, SMI

and serial port

n Slow CPU by dividing clock n Contextual save to disk.

Diagnostic software verifies system integrity automatically

The PC-510 has built-in diagnostic software that can be used to verify on-card I/O and memory functions. On powerup, a series of tests is performed. If a problem occurs, the failed test can be identified by the color sequence on an on-board, bicolored LED. The test is performed automatically every time the system is reset or powered up. Software, test equipment, monitor, keyboard, disks, or test fixtures are not required for memory verification. See the LED signaling and “beep” codes chapter for a complete listing of tests and failures and their descriptions.

SETUP information stored in EEPROM f or high reliability

Loss of SETUP data is serious in industrial applications. Most PCs store SETUP information in battery-backed CMOS RAM. If the battery fails or is replaced during routine maintenance, this information is lost. Without a keyboard and monitor in embedded applications, time consuming re-initialization is required. The PC-510 stores the SETUP information in EEPROM with 1,536 bytes available to the user. Software routines to use this available memory come with the PC-510.

Phoenix BIOS

The PC-510 has a Phoenix AT BIOS with power management and Octagon BIOS extensions. The AT BIOS supports up to four EIDE drives.

“Instant DOS” operating system

Datalight ROM-DOS v6.22 operating system is in flash. This means that this version is always present on powerup. The system boots and operates the same way as a desktop PC. Since all software and hardware are included, the system is fully operational “out of the box.”

Programmable video BIOS

The flash device contains a video BIOS, which controls the on-board SVGA controller. To support other flat panels, you can reprogram a new video BIOS. By default, the video BIOS supports a CRT and Sharp monochrome dual drive flat panel in simultaneous mode.

1-5

Overview PC-510 user’s manual

On-board flash file system

The Phoenix PICO FA flash file system controls the on-board SSDs, which allows read/write DOS access to the flash/SRAM devices. SSD0 can also use EPROM/OTPROM. For certain types of flash devices, the flash file system uses “wear leveling” to spread the usage and maximize the lifetime of these devices.

Octagon BIOS extensions

On-board BIOS extensions allow easy access to digital I/O, serial EEPROM, LCD bias control, watchdog timer functions, etc.

Interrupt routing: In system and pr ogrammable

Software is on-board the PC-510 to change the interrupt routing and some other features. The software allows more flexible use of interrupts on the PC-510 and outboard systems such as the PC/104 expansion card.

Floppy and hard disk ports

The floppy disk port supports two drives with either 720 KB or 1.44 MB capacities. The floppy port is terminated with a 34-pin IDC connector. The EIDE hard drive port is terminated with a 44-pin, 2 mm connector. +5V is supplied to a 2mm hard drive through the EIDE connector and +5V is also optionally supplied to the floppy drive through the IDC connector.

Boot sequence

A PC-510 can be configured to boot from the on-card, solid-state disk, an external floppy or hard disk.

Multifunctional printer port

The PC-510 incorporates the latest enhanced parallel port.

n Unidirectional n Bidirectional n IEEE 1284, ECP and EPP modes n 24 mA of drive current n Backdrive protection

The following represent applications in the multifunctional parallel port:

PC-510 user’s manual Overview

Watc hdog timer added for saf ety

The watchdog timer resets the system if the program stops unexpectedly. The watchdog is enabled, disabled and strobed under software control. The time-out is 1.6 seconds (typical).

Real time calendar/cloc k with battery-backup

The real time clock is fully AT compatible and uses the standard DOS calls. An optional off-card battery powers the real time clock when the 5 volt supply is removed. A connector is provided for the external battery. The real time clock also provides the user with 128 bytes of userdefined CMOS-RAM.

I/O connectors

With the exception of the mouse, keyboard, and IDE, all I/O connectors can be latched to prevent connector movement during shock or high vibration.

Keypad and LCD displa y support for low-cost operator interface

For embedded applications, the parallel printer port or the EZ I/O port can interface with a 16-key matrix keypad and a 2- or 4-line LCD display. The PC-510 is supplied with software that provides keypad scanning and display operation. Supplied display and keypad drivers in C support these devices.

Hardware reset

A hardware reset can be done by any of the following methods: n Issuing the RESET software command (using the watchdog

function)

n Depressing the reset switch n Cycling power n Configuring the opto channel for RESET.

A hardware reset ensures complete reset of the system and all attached peripherals. An expired watchdog timer cycle also causes a hardware reset to occur.

5 Volt operation lowers system cost

The PC-510 operates from a single 5V ±5% supply. Located across the power supply, the 6.2V, 5W zener diode protects against reverse voltage and limits over voltage. The power supply generates the RS-232 voltages on-board the PC-510. The locking power connector is a standard PC power header connector.

≡ PC-510 power supply requirements

The PC-510 is designed to operate from a single +5VDC supply. An AT compatible power supply connector header (P8, P9) is on board and ensures the required number of power and ground paths from the power supply. Make sure that you utilize all three +5 VDC conductors and all four ground conductors.

2-8

The power connector at P8, P9 also provides +/-12VDC and -5VDC required for any PC/104 expansion board. P8, P9 also supplies the correct voltage, +12 VDC, for flat panels that require back light operation. Refer to the P8, P9 power connector Table 2-1 for a complete listing of pinouts and their description.

PC-510 user’s manual Quick start

The maximum current requirements for the PC-510 is 2.0 A provided through P8, P9. It is important that a quality power supply be used with the PC-510. For example, when a particular application calls for a custom power supply, there are several internal issues to consider such as current capacity, line and load regulation, maximum ripple, hold up time, efficiency, and current limiting. The user should also consider the power devices and equipment such as the power cable conductor gauge, number and length of conductors, mating connectors, and the power supply to external devices such as hard drives, floppy drives, displays, mouse, and keyboard.

The proper selection of a quality power supply ensures reliability and proper functioning of the PC-510.

WARNING!

Make sure the power supply is OFF when connecting the power cable to the PC-510 board. Damage to the PC-510 may occur if the power is ON when connecting the power cable.

Chapter 4:

Save and run programs

≡ Save and run your programs on the PC-510

Once you have written, tested and debugged your application, you can then save it to flash memory in SSD1 or SSD0 (if flash or SRAM). When you reboot the PC-510, your program can automatically load into DOS memory and execute. As shipped from the factory, SSD1 already contains a bootable ROM-DOS.

This chapter describes the following:

n Saving an application program to SSD1 n Autoexecuting the program from the PC-510 n Overriding autoexecution of your program.

The information in this chapter assumes you are using ROM-DOS in your application. Some Microsoft programs make undocumented DOS calls. With ROM-DOS, an error returns when an undocumented DOS call is made, causing your program to operate erratically. We recommend booting from SSD1, using your own DOS, when using programs with undocumented DOS calls. Refer to the section Adding operating system startup files in the Managing SSDs chapter for more information on saving and autoexecuting programs.

≡ Saving programs and support files

By default, the drive in SSD1 comes preformatted from the factory, loaded with ROM-DOS startup files and an example demo program. To replace the demo program on SSD1 with your own, see the section Adding your application, in this chapter. To reformat an SSD or to add your own operating system, please refer to the Managing SSDs chapter.

WARNING!

Reformatting SSD1 requires the use of a floppy or a hard disk to restore system files.

4-1

Save and run programs PC-510 user’s manual

Adding your application

To add your application to your SSD, do the following:

1. Three methods of copying your application to the SSD are available. Do one of the following:

n From a local drive to the PC-510, issue the COPY command. n From a host drive, download your application by issuing the

TRANSFER command when using PC SmartLINK. Refer to the section, Transferring files between the PC-510 and your PC in the Transferring files/remote disks chapter.

n To establish a remote drive and copy from it, issue the REMDISK

and REMSERV commands. Refer to the section, Transferring files

between the PC-510 and your PC in the Transferring files/remote disks chapter.

2. Add or remove any device drivers for your application. You may want to do the same for the CONFIG.SYS file on SSD1. Remember to add these drivers to your drive as well.

3. To autoexecute your application, add your application name to the AUTOEXEC.BAT file. To replace our example program (DEMO.EXE) with your application, substitute DEMO in the AUTOEXEC.BAT file with your applications’ filename.

Autoex ecuting your application

This section describes how to autoexecute your application.

1. To autoexecute your application in SSD1, use the SETSSD command to define your SSD as the boot device. Since you need to define the order of SSD1 as the first of the SSDs (and before any IDE drives), enter the following command:

PC510 C:\> SETSSD SSD1 SSD0 /before

2. Reset the system. SSD1 is now drive C: and your application should begin execution.

Note If the SETUP option “Boot Sequence” is set to “A: THEN C:”, remove

any floppy in drive A: before resetting the system.

Note We recommend that you leave SSD0 in the SETSSD options or that you

have a copy of SETSSD.EXE on SSD1. This allows you to change your boot device back to SSD0 when needed.

4-2

Note The SETSSD options are not used when W2[9-10] is not jumpered.

Overriding the autoexecution of your application

You may stop the autoexecution of your application by doing one of the following options:

Option 1

1. Press F5 or F8 on your local keyboard. For more information, see your ROM-DOS manual.

Option 2

1. Change AUTOEXEC.BAT and/or CONFIG.SYS to not call out your program.

Option 3

1. Install a floppy.

2. Change SETUP option “Boot Sequence” to “A: THEN C:”

3. Change SETUP to enable the floppy.

4. Boot from floppy.

Interrupt status port

For example, if bits 5 and 4 are both 1, the interrupt status port address is 338h (default). If bits 5 and 4 are both 0, the interrupt status port address is 158h; if bit 5 is 0 and bit 4 is 1, the address for the interrupt status port is 138h; and if bit 5 is 1 and bit 4 is 0, the address for the interrupt status port is at 358h.

3. Inside your interrupt handler, read the interrupt status port. Bit 0 through bit 3 show which serial port caused the interrupt.

For example, when there is a 1 in bit 3, this means COM3 caused the interrupt; a 1 in bit 2 shows that the interrupt came from COM4; a 1 in bit 1 means that COM5 caused the interrupt; and by default, when a 1 is in bit 0, then COM6 caused the interrupt. See the table above to read the interrupt status port.

5-4

Note Exit the interrupt handler only when bits 0 through 3 are all at 0.

≡ Function and use of serial ports

COM1 as serial console device

Instead of the on-board local bus SVGA, you can use COM1 as the console device. See the Console devices chapter for more information. When COM1 is not used as a console device, then it is available to your program as a standard RS-232 port. Octagon Systems strongly urges that you leave COM1 at the 3F8h default address.

COM1 through COM6 as RS-232 I/O

COM1 through COM6 can also be used as RS-232 serial ports. Depending upon the design of each port, COM1 through COM4 can support 4- or 8-wire configurations, and COM5 and COM6 are 4-wire only configurations. Use a VTC-20F cable to interface from the PC-510 and the serial device.

≡ RS-485 network

An application may implement a node as either the “host” node or as a “remote” node in an RS-485 network. There can be as many as 32 nodes without any bus repeaters in the network. A “host” is referred to as the node that initiates communication; while a “remote” is referred to as a node that is addressed by the host.

In any given communication sequence in an RS-485 network, there can only be one host. The host is responsible for initiating communication, maintaining network registration, and providing housekeeping tasks with other nodes. Remotes, however, cannot initiate a communication. They can only respond to messages that are addressed to them from the host.

The following diagram demonstrates how a typical two-wire transmission is implemented in the RS-485 network.

LPT1 parallel port

≡ LPT1 parallel port

The LPT1 port has a 26-pin connector. It supports the unidirectional standard mode, bidirectional mode, enhanced parallel port (EPP) mode, and extended capabilities port (ECP) mode. The default I/O address is 378h (IRQ7). You may choose other nonstandard addresses between 278h (IRQ7) and 378h (IRQ7) in the PC-510 SETUP utility.

The LPT1 port supports a number of devices including a PC compatible printer, a multiline display, a matrix keypad or an opto rack with optoisolated digital I/O modules.

Note Make sure that the interrupt used for COM3 through COM6 does not

conflict with the IRQ selected for the LPT in SETUP.

≡ Printer

The following table illustrates the pinout for the LPT1 parallel port used as a printer port.

Note See the Accessories appendix for connector information on the LPT1

printer port connector.

Installing a printer

1. Make sure that the LPT1 port is in standard or bidirectional mode.

2. Connect an Octagon VTC-5/IBM cable from the LPT1 port (J6) to the 25-pin connector on your printer cable.

3. Connect the cable to your printer.

Chapter 7:

Console devices

≡ Description

The PC-510 has three options for console devices. You can use the onboard video with a monitor and a keyboard as your console. You can also use COM1 as the console or you can run the system without a console device.

≡ Selecting console devices

The following represent the PC-510’s three options for console devices: n Local bus SVGA and a local keyboard. The local bus SVGA can also

drive flat panel displays.

n Serial console from COM1. A serial cable/null modem adapter plugged

into a host PC running SmartLINK provides both input and output. The local keyboard also allows input.

n No console device means no video output, either from the SVGA moni-

tor or the serial console. The local keyboard allows input.

Local bus SV GA

For correct usage of the CRT and flat panel, see the CRTs and flat panels chapter.

Serial console

If the serial console is enabled and the video BIOSes are disabled, then COM1 acts as the console device.

Follow these steps to use the serial console:

1. Power off the PC-510.

2. Connect a VTC-20F cable to J7 of the PC-510. Refer to Figure 7-1.

3. Connect P2 (COM1 side of the VTC-20F cable) to the 9-pin null modem

adapter. Refer to Figure 7-2.

You can use any of the console options mentioned in the Selecting console devices section with a local keyboard.

Note See the Accessories appendix for connector information on the keyboard,

speaker, and mouse connectors.

Speaker

You can also use a local speaker with any of the console options listed above in the Selecting console devices section. Interface the speaker via a 4-pin connector at J1. You may use any external speaker from 8-50 ohms.

Mouse

You can also add the use of a mouse to the list of serial console devices mentioned in the Selecting console devices section in this chapter. The mouse connects to J3 on the PC-510.

≡ Enabling/disabling the video BIOS

The BIOS checks for a video BIOS to determine which console device to use. If a console device exists, the BIOS will use the console device, the CRT, or the flat panel. When the console device does not exist , the BIOS will otherwise use a serial console, if it has not been disabled in SETUP.

To enable/disable the video BIOS area, either change W2[1-2]/W3[1-2] or run SETUP and change C0000h-C7FFFh or C8000h-CFFFFh ROM enable options. The jumpers work as a toggle for the SETUP options. That is, if the SETUP previously shows the BIOS regions as “enabled,” then changing the state of W2[1-2]/W3[1-2] will disable the regions.

To verify the SETUP program’s state for the C0000h-CFFFFh regions, remove the USESETUP W2[9-10] and install W2[1-2] and W3[1-2]. This jumper installation enables the video BIOS areas. To allow for serial console use, disable the video BIOS areas by removing W2[9-10] and W2[1-2]/W3[1-2]. See Table 7-1 and Figure 7-3 as reference guides for disabling and enabling the video BIOS and changing ROM enable.

≡ SSD0 replaced with an SRAM device

Before replacing SSD0 with an SRAM device, do the following steps:

1. Since SSD0 is to be replaced with an unprogrammed device, the PC-510

must be configured to boot from SSD1. Run SETSSD.EXE to change the boot device:

PC510 C:\> SETSSD SSD1 SSD0

2. Power off the PC-510 and then make sure W2[5-6] is jumpered in order to

boot from the BIOS on SSD1.

8-1

SSDs, DRAM, and battery backup PC-510 user’s manual

3. Jumper W5[1-2, 3-4, 5-6, 9-10] and W2[7-8] for a flash device.

4. Install a 512K SRAM into SSD0 at socket U13.

5. Power on the PC-510 and format the flash device. See also the Manag-

ing SSDs chapter for more information.

Note SRAM contents are sometimes affected by system noise. Therefore, the

use of SRAM is not recommended in electrically noisy environments, especially when systems are critical. The SSD0 supports SRAM devices which are available only under OEM contract.

The SSD0 socket also supports flash and EPROM devices. By default, SSD0 reserves 192 KB for the system/video BIOS and 320 KB for a DOS drive. When an SRAM or flash device is used, the DOS drive is read/writeable through PICO FA. After PFORMAT has run, the SETSSD/SSD0BIOS- option allows the DOS drives on SSD0 to be the full size, 512 KB.

WARNING!

Alignment of an SRAM, flash, or EPROM device into SSD0 is critical. Be certain to properly align pin 1 of either the SRAM, flash, or EPROM device with pin 1 of SSD0 on the PC-510.

≡ SSD0 replaced with a flash device

Before replacing SSD0 with a flash device, do the following steps:

1. Power off the PC-510 and then make sure W2[5-6] is jumpered in order to boot from the BIOS on SSD1.

2. Since SSD0 is to be replaced with an unprogrammed device, the PC-510 must be configured to boot from SSD1. Run SETSSD.EXE to change the boot device:

PC510 C:\> SETSSD SSD1 SSD0

3. Power off the PC-510 and install a 512K flash into SSD0 at socket U13. Both W5[1-2, 3-4, 5-6, 9-10] and W2[7-8] must be jumpered for a flash device.

≡ Selecting an SSD BIOS

Each SSD may contain a system BIOS and a video BIOS. To select an SSD BIOS in SSD1, add jumper W2[5-6]. To use SSD0 BIOS, remove jumper W2[5-6]. See Table 8-2 for the proper settings. To program the system BIOS/video BIOS, refer to the Managing SSDs chapter.

≡ SSD1

Generally, SSD1 is meant for storing the application programs to be executed on powerup. The programs are automatically loaded into DOS memory and executed. The standard version of the PC-510 comes with a 2 MB flash soldered on-board, while the optional version contains a 1 MB flash soldered on-board. Your application programs can be saved to flash using the PICO FA driver which makes the flash device a read/ write disk on your PC-510. Saving your programs onto the read/write disk allows you to do this up to 100,000 times, allowing updates to your application programs. These devices are erased automatically during the programming process.

SSD1 can be accessed directly as a read/write DOS drive with the PICO FA driver. Also, it can be accessed directly as a read/write DOS drive when the PICOFA.SYS driver is loaded. While this is convenient for product development, the flash, however, has a limited number of writes allowed. Therefore, Octagon does not recommend SSD1 be used as a data logging device. Refer to the Software utilities appendix for information on supported flash devices and a description of PICO FA.

≡ DRAM

The standard version of the PC-510 is shipped with 1 MB of DRAM on-card. The PC-510 can also be configured with either 4 or 16 MB of surface mounted DRAM. The on-card DRAM socket holds up to a 16 MB dual in-line memory module (DIMM). The card supports fast page mode (FPM) or extended data out (EDO) types of memory. These

PC-510 user’s manual IRQ routing and opto IRQs

Chapter 10:

IRQ routing and opto IRQs

≡ Interrupt routing

The PC-510 provides a flexible method of enabling, disabling, and routing system interrupts via an “in system” programmable logic device. The logic device not only reduces the number of physical jumpers, but it also reduces the possibility of choosing the incorrect jumper configuration. For example, upon configuration the electronic jumpers remain set until they are reprogrammed for a different configuration.

This device also allows some of the PC/104 bus interrupts and some of the on-board generated interrupts to be routed to other IRQs of the programmable interrupt controller. This routing matrix requires the user to run the SETIRQ utility program to update the routing matrix with the desired IRQ routes.

In addition to IRQ routing, the I/O range select A and select B bits can be set so that the base addresses in COM5 and COM6, EZ I/O 1 and EZ I/O 2, and COM3 through COM6 IRQ status registers can be moved to different locations. These can also be read at I/O address 0A9h bits 4 and 5.

See also the SETIRQ.DOC file in the \IRQ directory on the PC-510 utility disk for more information. The utility disk contains several ISP files to program into the matrix. If these are not sufficient, call Octagon’s Technical Support at 303-426-4521 for new ISP files that may have become available.

Note If an output is not routed as a signal, then the output or destination is

neither driven high nor low, but is in a high impedance mode.

Note When you program a new IRQ routing matrix, the printer port must be

set to bi-directional mode. Also, any field devices connected to the printer port must be disconnected.

PC-510 user’s manual IRQ routing and opto IRQs

≡ Opto IRQs

OPTOA and OPTOB are the two optically isolated channels and are accessible at J17. These channels are configurable to drive either the SUSPEND/RESUME or the PMI signal. Also, either OPTOA or OPTOB can be routed through the interrupt routing matrix to generate a system reset. The opto-isolation allows the input source to extend as far as 50 feet from the card. A +5V signal activates the SUSPEND/RESUME, PMI or system reset signal. Noise filtering is built-in and the isolation from the system ground is 500V. A voltage greater than 3.1V at 5.0 mA guarantees a SUSPEND/RESUME or a PMI interrupt or a system reset.

When signaling for SUSPEND/RESUME, PMI, or system reset, the voltage is applied in a pulse period greater than 50 µS. The interrupt matrix chip requires that the input voltage remains stable until the interrupt is acknowledged. At that time, the interrupt source can be rearmed by returning the input to 0 volts.

Note See the Accessories appendix for mating information on the OPTOA and

OPTOB connectors. The interrupt routing matrix provides flexibility to the interrupt struc-

ture which allows connection between the lower-ordered ISA interrupts and the unused higher-ordered interrupts. Caution must be used when configuring the jumper options.

Note Bus IRQ6 can be inadvertently routed to two interrupts. This is not an

acceptable configuration. The application software must also be aware of the interrupt that is set for the particular resource.

≡ Interrupt routing matrix defaults

The 510_001.ISP file lists the interrupt routing matrix defaults. See the SETIRQ.DOC file on the PC-510 utility disk for more information.

≡ EZ I/O options

The PC-510 standard version is supplied with two Octagon EZ I/O digital I/O chips for a total of 48 I/O lines. Under OEM contract, the EZ I/O ports can be eliminated or only one port can be installed for 24 I/O lines.

Note See the Accessories appendix for connector information for the EZ I/O 1

and EZ I/O 2 connectors.

≡ Pulling the I/O lines high or low

Jumper block W4 pulls the I/O lines at ports A, B, and C high or low. This allows a known state upon powerup. The default configuration pulls all of the I/O lines high. Note that 10K ohm resistor networks are used to configure the I/O lines as high or low.

≡ Organization of ports

Each EZ I/O digital port has a total of 24 I/O lines connected to a 26-pin header. The lines are configured into three groups: ports A, B and C, each group consisting of 8 bits. Any of the lines at ports A, B or C can be configured individually as inputs or outputs.

Control register Base address + 3

Base I/O address

The base I/O address for EZ I/O 1 is 334h (default) and the base I/O address for EZ I/O 2 is 330h (default) but can be changed through OctaGlue PCS_2 to one of four addresses. Refer to the Interrupt routing section in the IRQ routing and opto IRQs chapter to change the base address of the EZ I/O chip.

Based on the I/O range select A and B, you can determine the port addresses for EZ I/O 1 and EZ I/O 2 by reading 0A9h bit 4 and 0A9h bit

≡ Configuring and programming the EZ I/O ports

J15 and J16, the digital I/O connectors, each have an Octagon EZ I/O digital chip associated with them. The EZ I/O chip has three ports with eight parallel I/O lines (bits) per port. This port can use one of four base I/O addresses. All lines can be individually programmed as all inputs, all outputs or individually as inputs or outputs. You can alter which bits are inputs or outputs by writing a control command to the control register of the EZ I/O. When a line is configured as an output, it can sink a maximum of 15 mA at 0.4V or can source 15 mA at 2.4V. On powerup and software or hardware reset, all digital I/O lines at J15 and J16 are reset as inputs.

PC-510 user’s manual EZ I/O

Programming the EZ I/O

Follow these steps to program the EZ I/O chip:

1. Configure the EZ I/O port bit directions, either as inputs or outputs.

2. Write to port A, B, or C with the desired level or read the bit level from the desired port.

Configuring the EZ I/O

Follow these steps to configure the EZ I/O chip

1. Write a "3" to the control register (base address + 3). This places the I/O chip in “direction” mode:

(default base address = 330h)

OUT 333h, 2 (control register, direction mode)

2. Set the direction of each bit. A "0" written to the corresponding line indicates an input and a "1" bit indicates an output. Each bit corresponds to the equivalent I/O line.

Table 11-6 EZ I/O port byte

bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0

For example, writing 00011100 to port C (base address + 2) will configure port C I/O lines 0, 1, 5, 6, and 7 to be inputs and lines 2, 3, and 4 to be outputs:

OUT 332h, 1Ch (00011100 binary = 1C hexadecimal)

3. Write a "3" to the control register (base register + 3). This places the I/O chip back into “operation” mode:

EZ I/O port I/O line

OUT 333h, 3 (control register)

11-5

EZ I/O PC-510 user’s manual

Writing and reading from EZ I/O

Writing to or reading from the desired EZ I/O port is accomplished with single program statements:

1. To write a bit pattern to the desired EZ I/O port:

OUT 332h, FFh

All bits of port C go high; all input bits are unaffected.

2. To read a bit pattern from the desired EZ I/O port:

PORTC = INP(332h)

The byte read from port C is assigned to variable port C.

EZ I/O output program examples

To configure ports A, B, and C as all outputs, issue the commands:

OUT 333h, 2 ‘Direction’ Mode OUT 330h, FFh ‘PortA’ OUT 331h, FFh ‘PortB’ OUT 332h, FFh ‘PortC’ OUT 333h, 3 ‘Operation’ Mode

Note With CAMBASIC, Octagon’s multitasking industrial language, you can

also accomplish the same configuration and outputs with one statement. Enter:

CONFIG EZ I/O &330, &0, &FF, &0, &FF, &0, &FF

Ports A, B, and C will now output all "1"s after issuing the following commands:

OUT 330h, FFh (portA) OUT 331h, FFh (portB) OUT 332h, FFh (portC)

or all "0"s after:

OUT 330h, 0 (portA) OUT 331h, 0 (portB) OUT 332h, 0 (portC)

EZ I/O input program examples

To configure ports A and C as inputs and port B as outputs, issue the following commands:

OUT 333h, 2 'Direction Mode' OUT 330h, 0 OUT 331h, FF OUT 332h, 0 OUT 333h, 3 'Operation Mode'

11-6

PC-510 user’s manual EZ I/O

To read ports A and C, issue the following commands:

PORTA = INP(330h) (port A) PORTC = INP(333h) (port B)
