6000 Series 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-500 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 component failure is very rare since the average MTBF of an Octagon card is greater than 11 years. In a 7 year study, Octagon has never found a single case where multiple IC failures were 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 nonfunctional”, 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.

6000 Series 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 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.

6000 Series user’s manual Overview n PICO FA flash file system makes flash memory appear as a hard disk to the PC Microcontroller.

n CAMBASIC, industrial control language includes drivers for all on-card hardware.

n The network kernel allows up to 32 systems to be linked into an

RS-422/485 network.

n The utility library includes application examples in C and

CAMBASIC.

n Diagnostic software is included to test the system on powerup.

CAMBASIC

CAMBASIC supports all on-card I/O including digital, analog, timing, interrupts, communications, and other functions. Thus, CAMBASIC eliminates the need to write hardware drivers. You spend your time writing the applications software rather than writing and debugging drivers.

Diagnostic software verifies system integrity automatically

The PC Microcontroller 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 a bicolored LED. The test is performed automatically every time the system is reset or powered up. No monitor, keyboard, disks, test fixtures, test equipment, or software is required.

See the LED signaling and “beep” codes chapter for a complete listing of system tests.

DRAM memory is fast and rugged

The PC Microcontroller has surface-mounted, fast page mode DRAM installed. The surface mounting is far more rugged than plug-in memory.

Solid-state disks withstand shock and vibration

SSD0 is a 1 MB flash memory disk containing the software suite in less than 512 KB, leaving more than 512 KB available for user programs.

The flash memory is seen by software as a hard disk. The use of the flash allows easy installation of software updates.

SSD2 is an SRAM with 128 KB capacity for data storage. SSD2 is battery-backed with an on-board battery.

Overview 6000 Series user’s manual

Boot sequence

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

Serial ports protected against ESD

The COM1 and COM2 serial ports are 16C550 compatible. The 16 byte

FIFO buffers minimize processor overhead in high speed serial communications. Baud rates are programmable from 150 to 115 KB baud.

Both ports have an RS-232 interface with the RS-232 voltages generated on-card. The serial ports meet the new IEC1000, level 3, ESD protection specification with ±8 KV of ESD protection. Backdrive protection is also included.

CAMBASIC supports the serial ports with interrupt driven, 2 KB input and output buffers which operate in the background. This ensures that data is not lost while critical control loops are being executed.

Note

The network interface module is not compatible with the 6010 model.

Convenient I/O termination with the breakout board (BOB)

Except for the serial and industrial I/O lines, all other I/O is terminated with a 34-pin IDC connector, also called the AUX I/O. The AUX I/O port eliminates cable clutter and the possibility of cables being plugged into the wrong sockets during maintenance. The breakout board terminates each function at the appropriate connector. These functions include the keyboard, speaker, printer, floppy drive, battery, and optoisolated interrupts.

Speaker and keyboard

The PC Microcontroller accepts a PS-2 style AT keyboard and provides speaker output through the breakout board (BOB).

Parallel port is multifunctional

The multifunctional parallel port can be used as a printer port or general purpose I/O. The parallel port can also interface with a floppy disk drive, drive alphanumeric displays and matrix keypads, or drive high current AC and DC loads using an opto rack and opto modules.

The multifunctional parallel port applications include: n LPT1 for PC compatible printers n 17 general purpose digital I/O lines n 4 x 4 matrix keypad n 4 line alphanumeric display

1-4

6000 Series user’s manual Overview n MPB-16PC, 16 position opto-module rack n Floppy disk drive

The printer port is IEEE 1284A compliant, unidirectional and bidirectional, EPP (enhanced parallel port) mode, and ECP (extended capabilities port) mode compatible. The printer port features backdrive protection and allows for much higher speed transfers than Octagon’s previous standard printer interface. The data lines can sink up to 24 mA. The printer port signals are routed through the PC Microcontroller’s

AUX I/O port when using the breakout board.

Keypad and LCD/VF display support for low cost operator interface

For embedded applications, a keypad and display (KAD) board and software are available to interface with an alphanumeric display and matrix keypad. The parallel port on the KAD can interface with a

16-key matrix keypad and a 2 or 4 line LCD or vacuum florescent display in applications where an inexpensive operator interface is needed. The microcontroller cards are supplied with the software which provides keypad scanning and display operation. The keypad and display board has sockets for the display and keypad. DISPLAY and

KEYPAD commands in CAMBASIC and drivers in C support these devices.

Industrial I/O is EZ I/O

Several PC Microcontrollers feature the Octagon EZ I/O digital I/O chip.

EZ I/O supplies 24 I/O lines which can be individually programmed as

5V input or 5V output. Each line can sink or source 15 mA. The 24 I/O lines are divided into three groups of 8 with 10 K resistors that can be connected to ground or +5V. The EZ I/O port can drive the MPB series opto-isolation module racks directly, controlling input and loads to 240V and 3A. CAMBASIC has several commands to support the EZ I/O port when working on bit, BCD, byte, or word bases.

High current outputs

Model 6050 dedicates 8 lines as high current outputs, capable of driving

100 mA loads rated up to 50V.

External interrupt and reset are optically isolated for safety

One opto-isolated input causes a master reset; and the other causes the system to generate an IRQ9. Both inputs accept voltages from 4.5 to 6

VDC. This could be used for an emergency stop, power failure, system synchronization, or a similar function. Drivers are provided in CAM-

BASIC and C.

1-5


Interrupts used to the maximum

Real time operation often requires many interrupts for high speed response to events. Five of the AT interrupts are connected to the ISA bus in addition to the four interrupts used on the card This provides the best use of the interrupts for demanding applications.

System expansion is flexible

The PC Microcontroller can expand via an 8-bit ISA unterminated backplane with the Octagon 5000 Series expansion cards.

Mounting

There are several ways to mount a PC Microcontroller: n Plug it directly into an Octagon Micro PC card cage. Power is supplied through the backplane.

n Use the optional PC mounting bracket and plug it into any passive

ISA backplane. Power is supplied through the backplane.

n Panel mount it using the four mounting holes for stand alone operation. A two position terminal connector is used to supply the 5V power.

n Stack it with other Micro PC cards. An Octagon two card stacking kit or a flexible backplane using 3M connectors and ribbon cable can be used to stack several cards together.

Hardware reset

A hardware reset can be done by any of the following means: n Issuing the RESET software command, using the watchdog function n Depressing the reset switch n Cycling power n Input from an optically-isolated 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.

Watchdog timer for added safety

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).

1-6

6000 Series user’s manual Overview

SETUP information stored in EEPROM for high reliability

The loss of SETUP data is serious in industrial applications. In the

PC Microcontroller, SETUP data is stored in nonvolatile serial

EEPROM eliminating the problem with battery or power failure

(with the exception of time and date). 512 bytes of the serial

EEPROM are reserved by the BIOS. An additional 1536 bytes are available to the user. A software driver is supplied for accessing the

EEPROM.

Real time calendar/clock with battery backup

The PC Microcontroller has a built-in AT style, real time clock. The real time clock is powered by an external AT style battery. For additional backup, an on-card battery powers the calendar/clock when the external battery is being replaced. The clock may be read either through DOS or CAMBASIC. The calendar/clock also provides the user with 128 bytes of user-defined CMOS-RAM.

Note: The date and time occasionally res ets to default. If your application requires date/time stamping you should consider another Octagon Systems CPU card.

Power management reduces power by more than 70%

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 70%, reducing the heat load and extending battery life in mobile applications.

Rugged environmental operation

The CPU case temperature may range from -40° to 85°C during operation at 25 MHz, or 0° to 60° C during operation at 40 MHz. The PC

Microcontroller is designed to withstand 10g shock and 2g vibration.

5 volt only operation lowers system cost

The PC Microcontroller operates from a single 5V ± 4% supply. Located across the power supply, the 6.2V, 5W diode protects against reverse voltage and limits over voltage. Power is supplied to the card either through the ISA bus connector or the terminal block.

6000 Series user’s manual Quick start

Chapter 2:

Quick start

This chapter covers the basics of setting up a PC Microcontroller system. The following topics are discussed: n Panel mounting, stacking, or installing the PC Microcontroller into an Octagon card cage n Setting up a serial communications console I/O link between the PC

Microcontroller and your desktop PC n Downloading files to the PC Microcontroller and running a program from the virtual drive.

WARNING!

The PC Microcontroller may not be installed in a PC. These cards are designed to be independent CPU cards only, not accelerators or coprocessors.

≡

Hardware installation

WARNING!

The PC Microcontroller card contains static-sensitive CMOS components. The card is most susceptible to damage when it is plugged into a card cage. The PC Microcontroller becomes charged by the user, and the static discharges to the backplane from the pin closest to the card connector. If that pin happens to be an input pin, even TTL inputs may be damaged. To avoid damaging your card and its components:

n Ground yourself before handling the card n Disconnect power before removing or inserting the card.

WARNING!

Take care to correctly position the PC Microcontroller in the card cage. The VCC and ground signals must match those on the backplane. Figure 2-1 shows the relative positions of the

PC Microcontroller as it is installed in the card cage.

Your PC Microcontroller can be installed in one of several ways: n Plugging it directly into an 8-bit Micro PC card cage n Using the optional PC mounting bracket and plugging it into any

8-bit passive ISA backplane n Panel mounting it using the four mounting holes n Stacking it with other Micro PC cards.

≡

Transferring files between the PC Microcontroller and your PC

Once you have established communications between your PC and the

PC Microcontroller, you can serially download files to any read/write drive used by the PC Microcontroller. You can then test and debug your application files. You can also upload files from the PC Microcontroller to your desktop PC for editing and debugging.

When booting from the PC Microcontroller BIOS drive, the default

CONFIG.SYS device drivers designate drive C: as the BIOS drive

(SSD0), drive D: as the SRAM drive (SSD2), and drive E: as the virtual drive. All drives assigned, can be accessed as read/write drives and files can be serially transferred to and stored on any of these drives.

Note

The virtual drive is optional when booting from SSD0, floppy drive or hard drive. If you do not need a virtual drive, do not use VDISK.SYS.

There are two methods to download files through the serial port to the

PC Microcontroller: n The TRANSFER utility is used to download files, one at a time, to the PC Microcontroller using the XMODEM protocol.

TRANSFER.EXE resides on the PC Microcontroller BIOS drive and on the PC Microcontroller utility disk and is used to send or receive files via the serial port (e.g., COM1). TRANSFER.EXE uses the

XMODEM protocol, as does PC SmartLINK. (See the note below on

XMODEM).

Note

In Windows 95 when the TRANSFER utility is used to download files, set the idle time sensitivity of PC SmartLINK on your desktop PC to

“low” for TRANSFER to run quickly. To change your settings, follow the steps below:

1. Open Windows Explorer.

2. Select SL.EXE with the right mouse button.

3. Select the Properties menu item.

4. Select the Miscellaneous tab in the Properties window.

5. Move the Idle Sensitivity slide bar to low.

6. Select the Apply button.

7. Exit the Properties window.

n REMDISK/REMSERV utilities allow access to all of the files on a remote disk drive. REMDISK.EXE and REMSERV.EXE are located on the PC Microcontroller BIOS drive and the PC Microcontroller utility disk. Once these programs are executed, single or multiple files can then be transferred to and from the PC Microcontroller using DOS COPY or XCOPY commands.

Note

REMDISK/REMSERV will not work with Windows 95. Use

REMDISK/REMSERV with ROM–DOS, MS–DOS, or on a network.

2-10


TRANSFER.EXE, REMDISK.EXE, and REMSERV.EXE are located on the PC Microcontroller BIOS drive, in the DOS directory, and on the PC

Microcontroller utility disk in the \DOS directory. Refer to the Software

utilities chapter for more information on these programs.

Note

XMODEM only transfers files in which the file size is exactly on a

128 byte boundary. If the file size does not fall exactly on the boundary,

XMODEM automatically rounds the file size up to the next 128 byte boundary with padding characters. For example, a file with a size of

10,000 bytes, will be rounded up to 10,112 bytes, transferred, and written with the new file size. In most cases, this is not a concern, but in some instances the XMODEM padding causes problems. The padding problems become apparent when an application program is expecting a specific file size or is expecting characters other than the padding characters to be at the end of the file.

The following information on downloading files between the PC Microcontroller and your PC uses the example program DEMO.EXE. This file is on the PC Microcontroller utility disk in the \DEMO directory.

Downloading files to the PC Microcontroller using

TRANSFER.EXE

The following procedures assume you are using PC SmartLINK and that it is included in your directory path. For other communication programs, refer to their instructions on sending a file from your PC to a target system. Refer to the Software utilities chapter for specific information on using TRANSFER.EXE.

Hardware and software requirements: n Desktop PC, running PC SmartLINK, connected by a VTC-9F cable and a null modem adapter to COM1 of the PC Microcontroller n A PC Microcontroller running TRANSFER.EXE out of COM1.

This chapter discusses running the SETUP configuration program, the

SETSSD program, and the PMISETUP program on the PC

Microcontroller.

n SETUP — Configures devices set up by the BIOS such as serial ports, floppy drives, etc.

n SETSSD — Configures PICO FA device order.

n PMISETUP — Configures power management options at a more detailed level than SETUP.

≡

SETUP

SETUP can be entered in one of two ways: n Running SETUP.COM

n Pressing the “backspace” key followed by the “S” key during BIOS

POST sequence (this occurs between the memory test and bootup).

Also, by removing the USESETUP jumper from the “S” position at W1, you may force the setup to temporarily revert to the defaults shown in the following table, which allows the user to reconfigure the setup.

The SETUP program defines the PC Microcontroller system parameters. It is shipped with default configuration parameters stored in the serial EEPROM. Changes are made by running the SETUP program.

The SETUP program is stored on the SSD0 drive and on the PC

Microcontroller utility disk.

SETSSD

SETSSD allows the user to set or change the PICO FA drive (SSD) order. PICO FA drives are “simulated” hard drives. They can exist before or after any IDE drives and can appear in any order. By setting the order, the SSDs may be accessed as C:, D:, etc. For example, n To set SSD0 first and SSD2 second, enter the following command:

60xx C:\> SETSSD SSD0 SSD2

If there are other hard drives on the system, add the /before option to place the order of the SSDs before the hard drives, or add the /after option to place the SSDs after the hard drives. For example, n To set SSD0 as the first drive, SSD2 as the second drive, and an IDE drive as the third drive, enter the following command:

60xx C:\> SETSSD SSD0 SSD2 /before n To set the IDE drive as first in order and SSD0 as second, enter the following command:

C:\> SETSSD SSD0 /after

In the last example, the IDE drive is C:, SSD2 is D: and SSD0 is E:.

Other drive letter designations may be added by device drivers (such as

VDISK.SYS), which are in the CONFIG.SYS file on the boot drive.

The boot drive is based upon the drive order set by the SETSSD command and by SETUP’s “boot sequence” option. If the boot sequence is set to “A: THEN C:,” the system will look for a floppy disk in drive A:. If a diskette is not installed, or a floppy is not defined, the boot drive will be the first drive specified in the SETSSD command. If the boot sequence is set to “C: ONLY,” the check for a disk is bypassed.

Note

The SETSSD parameters may also be overwritten by removing the

USESETUP jumper from the “S” position at W1 and resetting the system. If the parameters specified at the PICO FA first/second drive prompt are different from the previous SETSSD command, and you answered “No” to the “Save” prompt, the SETSSD output will not be accurate. Therefore, we recommend that you answer “Yes” to the save option to prevent confusion.

Note

After you run SETSSD and the drive order has changed, the new parameters will take effect after a reset.

Note

The drive order affects the number entered at the PFORMAT Hn command.

DOS call is made, causing your program to operate erratically. We recommend booting from SSD0 and using your own DOS, when using programs with undocumented DOS calls. Refer to the Adding operating

system startup files section in this chapter for more information on saving and autoexecuting programs.

This chapter also assumes you will be using the PC Microcontroller without a video card/monitor. If you are using these devices, refer to the Video chapter for more information on transferring and saving programs.

Saving program and support files

By default, SSD0 comes from the factory preformatted, loaded with

Datalight’s ROM-DOS startup files and with an example demo program. To replace the demo program on SSD0 with your own, see Add-

ing your application section in this chapter.

Formatting SSD0

This section describes how to format SSD0.

1. Define the SSD order with the SETSSD command. Since the command input varies depending upon the parameters you would need to enter, see the SETSSD command in the Software utilities chapter.

4-1

Save and run programs 6000 Series user’s manual

2. To begin formatting SSD0, execute PFORMAT as follows:

60xx C:\> PFORMAT H n where n is the hard drive sequence number. This number includes IDE drives and SSDs.

For example, if you have 0 IDE drives and SETSSD shows:

[hdd] SSD0 SSD2 then enter:

60xx C:\> PFORMAT H0

On the other hand, if you have 1 IDE drive, enter:

60xx C:\> PFORMAT H1

Note

If the drive has not been previously formatted, reset the system before accessing the drive. This allows DOS to recognize the drive and add a letter designation to it.

Note

PFORMAT.EXE must be downloaded from the PC Microcontroller utility disk. This file is located in the \UTILS directory.

After formatting the drive and resetting the system, you may access it as a normal DOS drive.

Adding operating system startup files (using SYS)

To add the system files, issue the following operating systems command:

C:\> SYS x: where x: specifies the drive letter.

For example, if your system has 1 IDE drive, and SETSSD shows “[hdd]

SSD0 SSD2,” then SSD0 should be drive D:. To SYS this drive, use the

“SYS D:” command.

Note

If you are adding the ROM-DOS operating system, SYS.COM must be downloaded from the PC Microcontroller utility disk. This file is located in the \DOS directory.

Note

If you are adding the MS-DOS operating system, you must first boot from an MS-DOS bootable device (floppy or hard drive).

Note

If you are not booting from ROM-DOS, and wish to SYS ROM-DOS back to the drive, the SYS command requires the access of the following

ROM-DOS files: COMMAND.COM, ROM-DOS.SYS and SYS.COM.

4-2

6000 Series user’s manual Save and run programs

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: a. From a local drive to the PC Microcontroller, issue the COPY command.

b. 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 Microcontroller and your

PC in the Quick start chapter.

c.

To establish a remote drive and copy from it, issue the REMDISK and REMSERV commands. Refer to the section, Transferring files

between the PC Microcontroller and your PC in the Quick start chapter.

2. Add or remove any device drivers from your application. Remember to add these drivers to your drive as well.

3. To autoexecute your application, add your application name to the

AUTOEXEC.BAT file. This method is the same in any DOS environment.

For instructions on downloading files using TRANSFER, REMDISK,

REMSERV, and PC SmartLINK, see the sections Transferring files

between the PC Microcontroller and your PC and Downloading files from

the PC Microcontroller in the Quick start chapter. In addition, the

Software utilities chapter provides usage instructions for REMDISK,

REMSERV, and TRANSFER.

Autoexecuting your application

This section describes how to autoexecute your application.

1. To autoexecute your application in SSD0, use the SETSSD command to define your SSD as the boot device. Since you need to define the order of SSD0 as the first of the SSDs (and before any IDE drives), enter the following command:

60xx C:\> SETSSD SSD0 SSD2 /before

2. Reset the system. SSD0 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

The SETSSD options are not used when USESETUP (“S” position at

W1) is not jumpered.

4-3

Save and run programs 6000 Series user’s manual

Overriding the autoexecution of your application

1. Remove the jumper from the “S” position at W1 (USESETUP).

2. Reset the system. This will force the system to ignore all SETUP information, including the floppy/hard drive and the SETSSD information.

3. At the prompt, “

PICO FA first drive (0=SSD0, 2=SSD2, other=no drive)

,” enter “0”.


PICO FA second drive (2=SSD2, other=no drive)

,” enter “2”.


Do you wish to save this information now?

(Y/N)

,” enter “Y”.

6. After saving this information, reinstall the USESETUP jumper.

7. Reset the system. The system should boot from SSD0.

6000 Series user’s manual Serial ports

Chapter 5:

Serial ports

≡

Description

Each PC Microcontroller in the 6000 Series has two serial ports, except for the 6030 which has 4 serial ports. These serial ports are 16C550 compatible. They can be used for interfacing to a printer, terminal, or other serial device. These ports support 5-, 6- 7-, or 8-bit word lengths,

1, 1.5, or 2 stop bits, and baud rates up to 115.2 KB.

The serial ports meet IEC1000, level 3, ESD protection specification with ±8 KV of ESD protection. Backdrive protection is also included.

COM2 can be converted to optically isolated, RS-422/485 with the network interface module (NIM). NIM mounts directly onto the PC

Microcontroller without the need of a cable or external power supply.

Note

The Network Interface Module (NIM) is not compatible with the 6010

PC Microcontroller.

Use a VTC-9F cable to connect the ports to external serial equipment.

The pinout of the connector allows you to plug the cable directly into a

9-pin PC serial connector (refer to the product-specific appendix for the connector pinout). When interfacing the PC Microcontroller to your PC, you will need to use a null modem adapter. The serial port at COM1 defaults to IRQ4 at I/O address 3F8H, which is the PC standard for

COM1. Likewise, the serial port at COM2 defaults to IRQ3 at I/O address 2F8H. Refer to Table 5-1 for the connector designation of each

COM port on your model in the 6000 Series.

Selecting console devices

The PC Microcontroller has two options for console devices:

1. Serial console from COM1, as selected with the SETUP program (“Serial

Console on COM1: ENABLED”). A serial cable/null modem adapter plugged into a host PC running PC SmartLINK provides both input and output. The local keyboard allows input.

5-1

Serial ports 6000 Series user’s manual

2. No console device (as selected with the SETUP program – “Serial

Console on COM1: DISABLED”) means no console output. The local keyboard allows input.

≡

COM1 as RS-232 I/O

When you have completed developing your application and programmed the PC Microcontroller, you can use COM1 as a standard RS-232 serial port for connection to a printer, modem, or other serial device. COM1 as a standard RS-232 serial port is configured at port address 3F8H. To access COM1 as standard RS-232, configure your serial port for your application or add a video card and monitor to your PC Microcontroller system. Use COM1CON.EXE to return to the serial port for console operation. Refer to the COM1CON.EXE support command in the Soft-

ware utilities appendix.

Use a VTC-9F cable to connect the ports to external serial equipment.

The pinout of the connector allows you to plug the cable directly into a

9-pin PC serial connector.

≡

Using QuickBASIC to communicate via COM1

Several programming languages including QuickBASIC assume a video card is present, and for system speed reasons write directly to the video hardware. Assuming that a video card is present can be a problem since many control applications require video output. The following discussion is directed at QuickBASIC, but the principles (not accessing the print routines which access the video memory directly) apply to many languages. There are several ways to use COM1 from QuickBASIC.

Systems with a video card

Add a video card to the system and open/close COM1 using the

QuickBASIC OPEN/CLOSE commands.

Systems without a video card

WARNING!

The system will lock up if you use commands such as PRINT or PRINT USING. Because QuickBASIC writes directly to video memory, these commands are usually displayed on a monitor.

5-2


Method 1

The system display will not appear over COM1 while the BIOS boots.

1. Run SETUP to disable the “COM1 as console” option.

2. Use QuickBASIC’s OPEN/CLOSE/PRINT/INPUT commands to access

COM1. The following is an example program using these commands:

OPEN "COM1:9600,N,8,1,BIN" FOR RANDOM AS #1

CRLF$=CHR$(13)+CHR$(10)

PRINT #1, "INPUT A STRING" + CRLF$

INPUT #1, A$

PRINT #1, CRLF$ + A$

CLOSE #1

Note

All PRINT/PRINT USING/INPUT . . . commands must use the COMx device number, where x represents the COM port used.

Method 2

1. Run SETUP to enable the “COM1 as console” option.

2. Use QuickBASIC’s OPEN/CLOSE/PRINT/INPUT commands to access

COM1. After closing the device, manually restore the serial parameters. The following example assumes 9600, N, 8, and 1 parameters:

OPEN"COM1:9600,N,8,1,BIN" FOR RANDOM AS #1

CRLF$ = CHR$(13) + CHR$(10)

PRINT #1, "INPUT A STRING" + CRLF$

INPUT #1, A$

PRINT #1, CRLF$ + A$

CLOSE #1

Note

All PRINT/PRINT USING/INPUT . . . commands must use the COM1 device number.

3. Restore the serial parameters by using a batch file specifying your program’s name as the first line of the file and COM1CON as the last line of the file.

For example, TEST.BAT may include the following to execute a user application named USECOM1:

USECOM1

COM1CON

Execute TEST.BAT.

COM1 will be used as a communication port by USECOM1, then COM1 is restored to a console port by COM1CON.

Note

COM1CON is located on the PC Microcontroller utility disk.

5-3


Method 3

1. Run SETUP to enable the “COM1 as console” option.

2. Use the PRINTS, PRINTSL, KEYHIT$, INKEY2$ commands as found in the DEMO.BAS and DSQBTEST.BAS programs (included on the PC

Microcontroller utility disk). Unformatted string output and string input must be done manually.

Note

Programs written in this manner will also work with a video card present and therefore systems can be “debugged” on your PC.

Method 4

1. Use an off-the-shelf communications library.

2. This may require restoring the COM1 parameters similar to Method 2, if the console video is expected after the QuickBASIC program terminates.

Method 5

1. Use COM2 instead of COM1. This is similar to Method 1, but you will still get the system displays over COM1.

Using Turbo C

If you need to restore the serial parameters after executing a C program, refer to the file COMTEST.CPP. This file can be downloaded from the Octagon Bulletin Board at (303) 427-5368 using 14400 baud, 8 data bits, no parity, and 1 stop bit.

≡

COM2

Operation

There are two modes of operations for COM2: n PC mode n Network mode

The “N” position at W1 distinguishes the COM2 mode on powerup. PC mode (“N” position at W1 jumpered, default) configures COM2 as a standard RS-232 port. Network mode (“N” position at W1 not jumpered) configures COM2 to communicate at 38.4 KB, respond to

Optomux type commands, respond to Octagon commands, and automatically perform network housekeeping functions.

5-4


PC mode/network mode

On powerup, the BIOS extension reads the “N” position at W1 to determine which COM2 mode to select.

Table 5-2 COM2 mode select

“N” position at W1

Not jumpered

Mode

PC mode

Network mode

Description

Use default configuration for

COM2 of 2400 baud, 8 data bits,

1 stop bit, and no parity.

Install IRQ3 vector.

Change default baud rate to

38.4 KB.

Read serial EEPROM bytes

120h,121h to determine if an ID has been previously established.

If it has, use the existing ID, if not, use FFh.

Discard messages addressed to other nodes. Selectively respond to messages addressed to node.

Await INT 17H BIOS calls to collect messages.

COM2 as RS-232 I/O

COM2 is a standard RS-232 serial port, default configured at port address 2F8H.

The “N” position at W1 distinguishes the COM2 mode on powerup. PC mode (“N” position at W1 jumpered, default) configures COM2 as a standard RS-232 port.

COM2 as RS-422/485

The PC Microcontrollers feature a predefined, easy-to-use software interface for using COM2 as an RS-422/485 port. This software interface supports Optomux type message-passing as well as additional

Octagon messages. Up to 32 nodes are supported at a default baud rate of 38.4 KB. This built-in feature provides a simple, low cost, and effective method of rapidly implementing an RS-422/485 network. An Octagon network interface module and an opto-isolated RS-232 to

RS-422/485 converter (Octagon P/N 4820), is required to convert RS-232 signals to RS-422/485.

Network mode (“N” position at W1 not jumpered) configures COM2 to communicate at 38.4 KB, respond to Optomux type commands, respond to Octagon commands and automatically perform network housekeeping functions.

5-5


Up to 32 nodes with valid ID range from 0 to FF are supported. ID 0 is reserved for the host. ID FF is reserved for a new node that connects to the network and has not yet been assigned an ID.

Both input and output ring buffer size is 2 KB.

Host/remotes

An application may implement a node as either the “host” node or as a

“remote” node in an RS-422/485 network. There can be up to 32 nodes without any bus repeaters in the network. A “host” is referred to as the node that initiates a communication; while a “remote” is referred to as a node that is addressed by the host.

The host is responsible for initiating communication, maintaining network registration, and providing housekeeping tasks with other nodes. There can only be one network host.

Remotes cannot initiate a communication. They can only respond to messages that are addressed to them from the host.

While there can be many remotes, all remotes initially respond to FFh as the ID before the ID is assigned or recognized by the host. To avoid conflict, only one new node at a time shall be added to the network.

Other unregistered nodes must not be powered up while the new node is being registered. This allows assigning each node a unique node ID.

Once a node has been added to the network and its ID stored in serial

EEPROM, any node can thereafter attach to the network in any powerup sequence. Periodically, the host shall try to communicate to all the existing nodes in the network, plus the potential new node with the

ID FFh.

Network interface module (NIM)

The Octagon network interface module (NIM) is designed for easy installation onto COM2 of the PC Microcontrollers. The NIM supports four-wire RS-422 and two-wire RS-485 configurations. Power is supplied to the NIM via the COM2 connector on the PC Microcontroller.

For more information about the network interface module, see the NIM

product sheet.

Note

The network interface module is not compatible with the 6010 model.

Checksum field

The checksum field of Octagon’s command set is computed by adding the ID field to the original Optomux type checksum. Note that by providing the checksum in this way, Optomux type equipment treats

Octagon’s add-on commands as invalid messages while Octagon’s equipment gains a unique set of commands.

Examples

Full C code examples are included in the \EXAMPLES directory on the

PC Microcontroller utility disk. The following examples are for concept only.

Example 1:

The following is a description of how Roll Call is implemented:

Host sends: (Dear node #1, are you there?)

>01AA3.

;>

; 01

; A

;message start character

;intended listener is ID 01

;command code A (roll call)

; A3 ;checksum = uchar (‘0’+‘1’+’A’+0x01) = 0xA3

; .

;message end character

Remote replies: (Dear 00: 01 is here. I have no special request.)

>00Z01007B.

;>

; 00

; Z


;intended listener is ID 00 (host)

;command code Z (reply to roll call)

; 01 ;01 = my ID

; 00 ;00 = status = no special request

; 7B;checksum = uchar (‘0’+‘0’+’Z’ +‘0’+’1’ +‘0’+’0’) = 0x7B

; .;message end character

Host sends: (Dear node #2, are you there?)

>02AA5.

;>

; 02



; A ;command code A (roll call)

; A5 ;checksum = uchar (‘0’+‘2’+’A’+0x02) = 0xA5

; .


Remote replies: (Dear 00: 02 is here. I have no special request.)

>00Z02007C.

; 00



; Z

; 02


;02 = my ID


; 7C;checksum = uchar (‘0’+‘0’+’Z’ +‘0’+’2’ +‘0’+’0’) = 0x7C


The host continues with the roll call until all nodes have been queried.

Not all of the 32 possible nodes need to be queried, only the known nodes. When the last known node has been queried, then the host queries for an unknown node.

5-12


Host sends: (Dear FF, are you there?)

>FFACC.

;>

; FF


;intended listener is ID FF


; CC ;checksum = uchar (‘F’+‘F’+’A’+0xff) = 0xCC

; 00



; Z

; FF


;FF = my ID


; A6;checksum = uchar (‘0’+‘0’+’Z’ +‘F’+’F’ +‘0’+’0’) = 0xA6


Example 2:

The following is a description of how an ID can be assigned to a new remote node:

Host sends: (Dear FF: are you there?)

>FFACC.

; >

; FF




; CC ;checksum = uchar (‘F’+’F’+’A’+0xff) = 0xCC

>FFC0533.

; >

; FF



; C ;command code C (assign ID)

; 05 ;new ID

; 33 ;checksum = uchar (‘F’+’F’+’C’+’0’+’5’+0xff)= 0x33

Remote replies: (Dear 00: FF acknowledges my new ID to be 05.)

>00XFF05A9.

; > ;message start character

; 00

; X


;command code X (reply to assign ID)

; FF ;FF = my ID

; 05 ;05 = my new ID

; A9 ;checksum = uchar (‘0’+’0’+’X’+’F’+’F’+’0’+’5’) = 0xA9


Example 3:

The following is a description of how a remote (of ID 02) can notify the host of a state change:

1. The application program sets internal state using INT 17h function 0fh.

2. The application program sets roll call reply status to 03 (ask for Report).

3. Since a remote cannot initiate a communication, it must wait until it is spoken to at this point.

Host sends: (Dear 02: are you there?)

>02AA5.

; >

; 02




; A5 ;checksum = uchar (‘0’+’2’+’A’+0x02) = 0xA5


Remote replies: (Dear 00: 02 is here. Ask for my internal state.)

>00Z02031F.

; >

; 00



; Z ;command code Z (reply to roll call)

; 02 ;02 = my ID

; 03 ;03 = status = Ask for a report of internal state

; 1F;checksum = uchar (‘0’+’0’+’Z’+’0’+’2’+’0’+’3’) = 0x1F


Host sends: (Dear 02: What is your internal state?)

>02DA8.

; >

; 02



; D ;command code D (Internal state query)

; A8 ;checksum = uchar (‘0’+’2’+’D’+0x02) = 0xA8


5-14


Remote replies: (Dear 00: 02 internal state = 47.)

>00W024784.

; >

; 00



; W ;command code W (reply to internal state query)

; 02 ;02 = my ID

; 47 ;47 = my internal state

; 84;checksum = uchar (‘0’+’0’+’W’+’0’+’2’+’4’+’7’) = 0x84


The application program interprets the message and then responds accordingly. In this case, state 47 would have been defined in the host application as a specific response from a Remote with a user-defined meaning.

Digital I/O lines

Several PC Microcontroller models feature the Octagon EZ I/O digital I/O chip. Each EZ I/O chip supplies 24 I/O lines which can be individually programmed as 5V input or 5V output. Each line can sink or source 15 mA.

EZ I/O lines can be used to sense switch closures, turn on lamps and LEDs, and interface with other devices that have TTL input or output such as printers and scales. The EZ I/O port can drive the Octagon MPB series opto-isolation module racks directly, controlling AC and DC loads to 240V at 3A. CAMBASIC has several commands to support the EZ I/O port when working on bit, BCD, byte or word bases. Figure 6-1 shows typical EZ I/O configurations.

6050 high current port

The high current port is used as dedicated outputs to drive relays,

LEDs, solenoids, and similar devices. The port includes eight I/O lines at J1, port B. These outputs switch loads to ground.

On powerup, all high current driver inputs are pulled LOW. This forces all high current outputs OFF. The user program must configure port B as outputs and then control the state of each bit of the port. The outputs of port B are inverted. A written logic 1 switches the current driver to

ON and switches current to ground. A written logic 0 opens the switch and the outputs are pulled high.

Note

When ON, the saturation voltages are incompatible with TTL logic levels and should not be used to drive other logic devices.

Considerations for high current outputs

n Each of the high current outputs can sink 500 mA at 50V. However, the package dissipation will be exceeded if all outputs are used at the maximum rating. The following conservative guidelines assume the number of outputs are on simultaneously. The following derating is based upon an ambient temperature of 70° C.

150 mA n Since the thermal time constant of the package is very short, the number of outputs that are on at any one time should include those that overlap even for a few milliseconds.

n Incandescent lamps have a “cold” current of 11 times that of their

“hot” current. It is recommended that lamps requiring more than

50 mA not be used.

n When inductive loads are used, protection diodes or other schemes must be used. Refer to Figure 6-4.

Figure 6-5 Inductive load protection circuitry

+ Supply

1N4002

(To High Current Output)

n Configuring outputs in parallel for higher drive is NOT recommended and could result in damage since the outputs will not share current equally.

WARNING!

If external devices, such as 24 VDC relays, are driven, the ground of the external 24V supply must be connected to J1, pin 26 and NOT the power ground. Failure to do so will produce aground loop within the PC Microcontroller and can cause erratic operation.

Configuring and programming the EZ I/O ports

On powerup and software or hardware reset, all digital I/O lines are reset as inputs.

Each digital I/O connector has an Octagon EZ I/O digital chip associated with it. Each has three ports with eight parallel I/O lines (bits) per port.

The address of the port is determined by jumper settings as follows:

On the 6040 PC Microcontroller, ports A, B and C can be programmed as all inputs, all outputs or individually as inputs or outputs. On the 6050 PC

Microcontroller, port B can only be programmed as outputs, while ports A and C can be programmed as inputs or outputs. You can alter which bits are inputs or outputs by writing a control command to the control register in 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.

Programming EZ I/O

Program the EZ I/O chip as follows:

1. Configure the bit directions.

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

Configuring EZ I/O

Configure the EZ I/O chip as follows:

1. Write a “2” to the control register (base address+3). This places the I/O chip into the “direction” mode:

OUT 143H, 2

(control register)

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

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:

6-14


OUT 142H, 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:

OUT 143H, 3

(control register)

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 142H, 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(142H)

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 command:

OUT 143H, 2

‘Direction’ Mode

OUT 140H, FFH

‘Port A’

OUT 141H, FFH

‘Port B’

OUT 142H, FFH

‘Port C’

OUT 143H, 3

‘Operation’ Mode

Note

With CAMBASIC, you can also accomplish the same configuration and outputs with one statement. Enter:

CONFIG EZIO &140, &0, &FF, &0, &FF, &O, &FF

Syntax

The CAMBASIC syntax is as follows:

CONFIG EZIO address, dirA, initA, dirB, initB, dirC, initC

Parameters

Parameters are defined as follows: n address specifies the base address of the Octagon EZ I/O parallel I/O device in use.

n initA, initB, and initC specify the logic state of portA, port B, and port C, respectively, when this statement is executed. The value range is 0 to 255.

n dirA, dirB, and dirC are the directions of port A, port B, and port C, respectively. The value 0 of an individual bit specifies output and the value 1 specifies input.

Note

Usually, once the chip is configures with the CONFIG EZ IO statement, there is no reason to reconfigure this statement again

6-15


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

OUT 140H, FFH

(port A)

OUT 141H, FFH

(port B)

OUT 142H, FFH

(port C) or all “0”s after:

OUT 140H, 0

OUT 141H, 0

OUT 142H, 0

(port A)

(port B)

(port C)

Note

The outputs of port B on model 6050 are inverted due to the ULN2804 high-current Darlington array.

EZ I/O input program examples

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

‘Direction Mode’

OUT 143H, 2

OUT 140H, 0

OUT 141H, FF

OUT 142H, 0

OUT 143H, 3

‘Operation Mode’

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

PORTA = INP(140H)

(port A)

PORTC = INP(142H)

(port C)

Note

Port B is used as output on the 6050 PC Microcontroller.

Chapter 7:

AUX I/O

≡

Description

The AUX I/O port is a 34-pin connector at J2 which incorporates the parallel printer, speaker and keyboard ports, two optically isolated interrupts, and the AT battery connection. An alphanumeric display, matrix keypad, or floppy drive also interface through this port. These features are easily accessed through the use of the breakout board or through the construction of a breakout cable. See the product-specific appendix for the

AUX I/O connector pinout.

≡

Breakout board (BOB)

The breakout board (BOB) is designed for use with all 6000 Series PC

Microcontrollers. Keyboard, printer, speaker, optically isolated interrupt and reset, and an optional AT battery, are connected from the breakout board to the PC Microcontroller through the 34-pin AUX I/O header. The

AUX I/O header provides a convenient and quick method of disconnecting these external devices from the PC Microcontroller during maintenance.

Note

The AUX I/O port supports either a printer, an MPB-16PC opto-rack, a floppy drive, or can interface to a keypad and alphanumeric display, but not to all at the same time.

6000 Series user’s manual SSDs, DRAM, and battery backup

Chapter 9:

SSDs, DRAM, and battery backup

Before you can save and boot your application from the PC Microcontroller, this chapter describes how to configure the system for your particular application requirements. The following topics are discussed:

SSD0

SSD2

DRAM

Real time clock

Battery backup for SSD2 and real time calendar/clock

≡

SSD0

SSD0 contains the BIOS and ROM-DOS 6.22 in flash ROM. It reserves

128 KB for BIOS and 896 KB for a drive area. SSD0 is a DOS-compatible read/write drive.

Your application programs can be saved to flash using the PICO FA driver which makes the flash memory a read/write disk on your PC

Microcontroller. Saving your application programs onto the read/write disk allows you to update them at least 100,000 times. These devices are erased automatically during the programming process.

SSD0 can be accessed directly as a read/write DOS drive with the PICO

FA driver in the BIOS extension. 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 SSD0 be used as a data logging device. Refer to the Software

utilities chapter for information on supported flash memory and a description of PICO FA.

≡

SSD2

SSD2 contains 128 KB of SRAM. SSD2 can be accessed directly as a read/write DOS drive with the PICO FA BIOS extension. SSD2 is generally used for data logging.

WARNING!

The on–board battery is not intended to back up SSD2. Use an external AT style battery to back up SSD2. Failure to do so may result in lost data.

9-1

SSDs, DRAM, and battery backup 6000 Series user’s manual

≡

DRAM

The PC Microcontrollers are shipped with 2 or 4 MB of fast page

DRAM surface mounted on-card.

≡

Real time clock

The PC Microcontroller has a built-in AT style, real time calendar/ clock. The clock may be read either through DOS or CAMBASIC.

Note: The date and time occasionally resets to default. If your application requires date/time stamping you should consider another

Octagon Systems CPU card.

≡

Battery backup for SSD2 and real time calendar/clock

The PC Microcontroller cards contain a 3.6V Lithium battery on card.

This battery is intended as a backup battery only, to protect data in

SRAM and the real time clock while an external battery is being changed. Using the on card battery for these functions can reduce the lifetime to approximately two years. In addition, the margin between the battery voltage and the switchover threshold can be reduced prematurely, causing lost data. This is particularly noticeable in noisy environments.

If you are backing up SRAM, or depending on the real time clock, connect an external AT battery to the battery connector J6.

For critical applications such as medical, or data-logging applications where the CPU is powered off for extended periods, you can connect an additional battery to pin 7 (battery) and pin 3 (ground) on connector J2

(AUX I/O header). The breakout board (BOB), which connects to the

AUX I/O header, contains a connector for an AT style battery.

Drive Cards which support IDE type hard drives. The hard drive BIOS is also included in the PC Microcontroller BIOS. Instructions for installing either type of hard drive is explained below.

The PC Microcontroller supports the latest EIDE BIOS. We highly recommend that this BIOS is used rather than the 5800A or 5815 BIOS.

Before you begin installing an off-card hard drive, see the SETSSD section in the Setup programs chapter. The SETSSD section provides instructions for setting the disk drive designation.

You may use one of two methods to configure the system for a 5815.

Both methods are described below.

Disabling 5815 or 5800A BIOS and using the PC

Microcontroller IDE BIOS

This method allows the use of an IDE controller, such as the 5815 or

5800A. It involves disabling the 5815 or 5800A BIOS and using the PC

Microcontroller IDE BIOS. The procedure is as follows:

For the 5815:

1. Using SETUP, configure the PC Microcontroller for one hard drive by running SETUP and setting the appropriate options.

2. Configure the 5815 to disable the on-card BIOS. See the 5815 product

sheet for the proper jumper settings on the 5815.

Note

Bus IRQ5 is redirected to CPU IRQ14.

For the 5800A:

1. Using HDSETUP.COM, configure the 5800A to have 0 hard drives. See the 5800A product sheet for more information.

2. Using SETUP, configure the PC Microcontroller for one hard drive by running SETUP and setting the appropriate options.

Using the hard drive controller BIOS and disabling the PC

Microcontroller BIOS

This method applies when using a 5815 or 5800A. It involves using the hard drive controller BIOS and disabling the PC Microcontroller BIOS.

1. Using SETUP, configure the PC Microcontroller for “0” hard drives.

2. Run HDSETUP, provided with the 5815 or 5800A, to configure the hard drive controller card for the proper hard drive parameters. Also, set the

IRQ to IRQ14.

3. If using the 5815, verify that the jumper setting enables the on-card

BIOS. See the 5815 product sheet for proper jumper positions.

IRQ routing and opto IRQs

≡

Interrupt routing

The PC Microcontroller provides routing of several interrupts that originate from the 8-bit ISA bus to use additional AT interrupts. This interrupt routing provides flexibility to the interrupt structure, allowing the lower-ordered XT bus interrupts to be connected to the unused higher-ordered AT interrupts.

The 8-bit bus interrupts that are routed are: n Bus IRQ3 to IRQ10 n Bus IRQ4 to IRQ11 n Bus IRQ5 to IRQ14

The dedicated on-card interrupts are: n IRQ3-COM2 n IRQ4-COM1 n OPTO A-remote reset n OPTO B-IRQ9

Counter timer controller

Counter timer controller

Note

The counter timer controller is only available on the 6020 PC

Microcontroller.

≡

Description

The 6020 has an 82C54 counter timer controller (CTC) to provide periodic interrupts to the CPU for time related I/O events such as data logging. Two time bases are available: 1.8 MHz and 7.2 MHz. These time bases are jumper selectable through W2. Refer to Table 15-1.

The CTC chip consists of three counter/timer circuits. Counter 2, which has either a clock input of 1.843 MHz or 7.159 MHz, acts as a pre-scalar for counters 0 and 1. The output of counter 2 is routed to the clock inputs of both counters 0 and 1. Gate inputs to counters 0 and 1 are tied together and are either pulled high or controlled by the control signal, CTC Gate Enable. The outputs of counters 0 and 1 then provide

IRQ12 and IRQ11, respectively, to the CPU.

Counter timer controller 6000 Series user’s manual

Note

The 82C54 is an extremely versatile component which has six modes of operation, a Read Back command, and a Counter Latch command. The primary intent, however, is to use the 6020 CTC for providing periodic interrupts to the CPU and not to discuss all functions associated with the CTC. For further information, refer to the Intel peripheral 82C54

data sheet or the NEC 71054 data sheet.

This section provides an overview of the 6020 CTC. A programming example, 6020_CTC.CPP, is included on the 6020 utility disk, which demonstrates using CTC counters 0 and 1 to generate periodic interrupts.

To adequately explain the counter timer controller, the 6020 CTC is presented in three functional sections: n Address mapping n Interrupts n Counter /timers

≡

Address mapping

The base address of the CTC is jumper selectable. Refer to Table 15-1 for the base address selection.

Note

Selecting a different CTC I/O address also selects a different I/O address for the EZ I/O digital ports. For information on EZ I/O, refer to the

EZ I/O section in the EZ I/O chapter.

It is important that no other devices in the system be set for access at the same I/O locations as the 6020 CTC or EZ I/O ports. The CTC mapped locations consist of four separate I/O addresses.

15-2

6000 Series user’s manual Counter timer controller

The following addresses each access a different function of the CTC: n Base+0 = CTC counter 0 n Base+1 = CTC counter 1 n Base+2 = CTC counter 2 n Base+3 = CTC control register

Refer to the Counter/timers section for details on each I/O location and their functions.

≡

Interrupts

The outputs of CTC counters 0 and 1 are used to provide periodic interrupts to the 6020 CPU. The output of counter 0 is routed to IRQ 12, and the output of counter 1 is routed to IRQ11.

≡

Counter/timers

The CTC has three separate counter/timers included in one package.

Three data registers are associated with the control register. After powerup, the state of the 82C54 is undefined because the mode and count value of all counters have not been defined. The operation of each counter is determined after it is programmed. Each counter must be programmed before it can be used. Unused counters, however, do not need to be programmed.

Note

Since the CTC mainly functions as an interrupt generating device, it is important to disable interrupts prior to programming the CTC and then re-enable the interrupts.

The following define each section of each counter/timer:

CTC CLOCK inputs

CTC GATE inputs

CTC outputs

Any negative transition on the CLOCK input will decrement the numeric value of the count registers.

The GATE input, when true, allows the CLOCK signal to decrement the value of the count.

Depending on the mode, the OUT signal will either toggle or pulse when the count value reaches 0.

Each of the above counter/timer counters can operate in one of six different modes. For more information on the different modes, refer to the Counter/timer modes section.

Programming the counter/timers

Each counter must be programmed with the desirable mode and then with an initial count before it can be used. This is accomplished by writing a control word and then an initial count. The control word is written in the form of a formatted byte to the CTC control register

(Base+3).

15-3


Example

OUT &153, &76 Writes a 76h as a control word to the CTC control register and configures a selected counter.

OUT &150, &AA Writes the count value of AAH to the counter. The counter is determined in the 76h control word.

Examples of a CTC control word:

00111010 = 3A hex

Select Counter = Counter 0

RW = Least significant byte then most significant byte

Mode = Mode 5 hardware triggered strobe

BCD = Binary counter 16 bits

01110110 = 76 hex



Mode = Mode 3 square wave generator


10110100 = B4 hex



Mode = Mode 2 rate generator


Examples of the count value

A count value is then loaded after the counter has been configured.

&4800 is equal to 18432 decimal. If the 1.843 MHz clock is divided by this value, the result will be 100. Therefore, if counter 2 is loaded with this count, the OUTPUT will cycle every 1/100 of a second or 100Hz.

&64 is equal to 100 decimal. If this value is loaded into counter 0 and since the 100 Hz output of counter 2 is routed to counter 0 CLOCK, the output generated from counter 0 will cycle once every second or 1 Hz.

The selected counter may then require the GATE to change states before counting begins. How the OUTPUT appears (Square Wave,

Strobe, etc.) will depend on how the counter was configured. Refer to the Control word definition section .

A programming example, 6020_CTC.CPP, is included on the 6020 utility disk, which demonstrates the use of CTC counters 0 and 1 to generate periodic interrupts.

Control word definition

The control word sets the counter/timer to a specific mode of counting.

In addition to the various counting modes, the setup in Table 15-2 should be considered:

Definition of CTC modes

To begin counting, several CTC modes require the GATE to toggle.

Modes 1, 4, and 5 require control of the GATE. The GATE address is always 0xA8, bit 4. The GATE of the 6020 counter 2 is always enabled, therefore only Modes 0, 2, and 3 are effective for counter 2. The GATEs for counter 0 and counter 1 are tied together and are either pulled high or enabled by CTC Gate Enable so all modes can be used for these counters. Since the primary purpose of the 6020 CTC design is to

15-6

6000 Series user’s manual Counter timer controller generate periodic interrupts, modes 2 and 3 will be most effective. The programming example, 6020_CTC.CPP, demonstrates the use of modes

2 and 3.

Mode 0 – Terminal count

The terminal count mode is generally used to count external events.

Because the 6020 CTC is not accessed externally, this mode will not be discussed.

Mode 1 – Hardware retriggerable one shot

To make this mode useful, load a count into either counter 0 or counter

1, or both, and then start the count by enabling the GATE. Once the count has been reached, an interrupt will be generated from the associated counter. This mode requires control of the GATE and, therefore, cannot be used for the counter 2 pre-scaler.

After the control word is written, OUT goes HIGH. A count value N is written to the counter and the one shot is now armed. Any positive transition of the GATE signal is latched and the next positive transition of the CLOCK signal enables the one shot. The OUT signal will go

LOW on the next negative CLOCK transition and remain LOW for N negative transitions of the CLOCK signal. When the COUNT value N reaches a value 0, OUT will return HIGH. The ONE SHOT is retriggerable and any positive transition on the GATE input will reload the ONE SHOT time, which keeps OUT low for another N intervals of

CLOCK transitions.

Mode 2 – Rate generator

The rate generator mode generates an output pulse at a periodic rate.

This mode is often used for counter 2, which is the pre-scalar for counters 0 and 1. Since the GATE of counter 2 is always enabled, counter 2 operates in this mode. Once the count has been reached, an output will be generated.

The OUT signal is set HIGH after the control word is written. After the

COUNT value N is written, the counter is loaded and begins to decrement on CLOCK cycles. When the COUNT value reaches 0, OUT will go LOW for one CLOCK period and then return HIGH. The N value is automatically reloaded into the counter and is decremented on subsequent CLOCK pulses.

The GATE input is HIGH, which enables the counter. If the GATE input is LOW then counting is inhibited. If GATE goes LOW during an

OUT pulse, OUT is immediately returned to a HIGH. On the rising edge of GATE the initial N value reloads on the next CLOCK pulse.

The value decrements on subsequent CLOCK pulses.

Note

A COUNT value of “1” is illegal in Mode 2.

15-7


Because the interrupts are typically edge triggered, the interrupt is not generated until OUT goes low and then high again (CLOCK count +1).

Mode 3 – Square wave mode

This mode is useful when it is necessary to generate a Square Wave output. This mode will be used most often for counter 2, which is the pre-scalar for counters 0 and 1. Since the GATE of counter 2 is always enabled, counter 2 will operate in this mode. Counters 0 and 1 can also use this mode to further divide the output of counter 2. The OUT signal is HIGH after the control word is written. After the COUNT value of N is written, the OUT signal will go LOW on the negative edge of the next

CLOCK cycle. If N is an EVEN number, OUT will remain LOW for N/2

CLOCK cycles, if N is an ODD number, OUT is LOW for N/2 + 1

CLOCK cycles. OUT then goes HIGH and remains HIGH until N equals 0. The value N is then automatically reloaded into the counter and the period repeats.

The GATE input being HIGH enables the counter. If GATE input is

LOW then counting is inhibited. If GATE goes LOW while OUT is

LOW, OUT will go HIGH immediately. The positive transition of GATE will reload the count value of N into the counter on the next CLOCK cycle. The COUNT value will then be decremented on subsequent

CLOCK cycles.

Because interrupts are typically positive edge triggered, the interrupt will not be generated until OUT goes low and then high again (CLOCK count +1).

Mode 4 - Software triggered strobe

This mode can be useful when no external events are needed or provided to generate an interrupt by the CTC. Once the count at counter 0 or counter 1 has been reached an interrupt will be generated. This mode requires control of the GATE and, therefore, cannot be used for the counter 2.

This mode is useful in order to generate a one CLOCK pulse width

OUTPUT after a COUNT value of N has expired. The OUT signal is

HIGH after the control word is written. After the COUNT value of N is written, the value is loaded into the counter on the next CLOCK cycle.

The value is not decremented on this cycle. The OUT signal remains

HIGH until the counter reaches a 0 value. OUT then cycles LOW for one CLOCK period. OUT will then remain HIGH after this cycle until a

COUNT value is rewritten to the counter.

GATE input equal to 1 enables the counter.

GATE input equal to 0 inhibits the counter.

The GATE input does not effect the OUT signal in any other way.


15-8


Mode 5 – Hardware triggered strobe

This mode can be useful by loading a count into counter 0 or counter 1 and then starting the count by enabling the GATE. Once the count has been reached an interrupt will be generated. This mode requires control of the

GATE and, therefore, cannot be used for the counter 2 pre-scaler.

This mode is useful in order to generate a one CLOCK cycle width OUTPUT triggered by GATE, after a COUNT value of N has expired. The OUT signal is HIGH after the control word is written. The COUNT value of N is then written. A POSITIVE transition on the GATE input is then required. The next CLOCK cycle loads the COUNT value into the counter, and subsequent

CLOCK cycles decrement the counter. When the counter reaches a value of 0 the OUT cycles LOW for one CLOCK period. GATE does not inhibit the counter or effect the OUT signal. Any POSITIVE transition of the GATE input will reload the COUNT value N into the counter and the counting will continue.

Chapter 18:

CPU power management

CPU power management

≡

Description

The power management for the PC Microcontrollers in the 6000 Series only functions in DOS. The power demands of a system can severely limit an application due to thermal constraints or the raw power usage in a battery-operated application. To maintain speed and efficiency, a software-controlled, power management system must be tailored to the application. Even if your application is operating within specified limits, a power management system may improve the life and reliability of your system by reducing thermal stress to the CPU.

Power management can be enabled in the PC Microcontroller SETUP program and fine tuned with the PMISETUP program. DOS-supplied advanced power management (APM) programs, such as POWER.EXE

are also supported. See the PC Microcontroller utility disk for a list of example programs located in the \EXAMPLES directory. For more information on using the SETUP utility, refer to the Setup programs chapter. For more information on using the PMISETUP utility, see the

PMISETUP section later in this chapter.

≡

Power management overview

Power management is implemented via the software management interface (SMI) function, and provides multiple levels of management.

The firmware is also capable of cooperative power management with an

APM compatible driver or application, such as POWER.EXE. Cooperative power management allows power aware applications to control the power state of the system without depending on interrupts or device access to indicate that the CPU is actively executing application code.

At the hardware level, the power management system cannot detect

CPU activity except by monitoring bus activity such as interrupts or access to specific memory or I/O address ranges.

The hardware is capable of minimal levels of power management without interacting with the firmware at all. For example, once the IDLE timer is configured by the firmware, the IDLE timer monitors specific activities and enters the halt state after periods of inactivity. These activities are monitored constantly to determine if power management is suitable. If the specific events do not occur, the IDLE timer will eventually expire, which places the system into the SUSPEND state where devices can be optionally powered down. At the same time, the

CPU is in the HALT state to conserve power. While the CPU is in the

HALT state, specific events can be monitored to RESUME the system to full power.

18-1

CPU power management 6000 Series user’s manual

In a stand-alone environment (no APM software active), the firmware works in conjunction with the hardware doze timer and monitoring functions to identify periods when certain devices or the entire system are inactive. Individual timers are supported for specific devices, including the hard disk. Whenever this device is not accessed for a specified period, it is powered down to reduce system power consumption. Whenever none of the monitored system devices has been accessed for a specified period of time, the performance of the system is reduced or the

CPU is halted altogether to further reduce power consumption.

In a cooperative environment, devices are still controlled by the firmware, but the CPU is never halted without the consent of the APM software. Rather, the firmware notifies the software when a timer has expired or some other event has occurred which should place the system in a reduced power mode. The APM software polls the firmware for such events. Once an event has occurred, the software initiates the reduced power mode by acknowledging the event back to the firmware.

The firmware then initiates the reduced power mode. The APM software can inquire “APM aware” applications to ensure that the reduced power mode is acceptable.

≡

Hardware controlled modes

The IDLE timer is configured to reset by specific events which include the keyboard, video, hard disk, line printer, serial port, floppy disk, and selected IRQ or DRQ activities. When these specific events do not occur, the system enters the SUSPEND mode. In this mode, devices such as the hard disk, floppy disk, parallel port, serial ports, video, super I/O, and peripheral chip are powered down to conserve power.

In addition to powering down these specified devices, the CPU then enters the halt state. The hard disk, parallel port, video, real time clock, IN access, DRQs, GP0 (memory access at E8000h-EFFFFh) and

GP1 (I/O access at 3xxh) are specified events that are configured to resume the system from the SUSPEND state.

≡

Device power management

The hard disk is power managed on an individual basis. The firmware configures a hardware timer that is reset each time the device is accessed. If there is no access to the hard disk, the timer will eventually expire and the hard disk will then power down to conserve power.

Later, when the hard disk is restored by a triggering event, such as a keystroke, the access SMI is disabled and the timer is restarted.

18-2

6000 Series user’s manual CPU power management

≡

System power management

At the system level, power management is very similar to the device level management, with a few exceptions. Cooperative management is supported, allowing an APM driver, such as POWER.EXE, to control the actual power state transitions. This is done by identifying power management events and reporting them to the APM driver via a polling mechanism. Power state transitions then occur at the request of the

APM driver.

The IDLE timer can be reset by numerous sources, including device accesses and interrupts. Note that it is possible for the IDLE timer configuration to be of shorter duration than the device timers. This means that the system can be deemed IDLE even though some of the devices are still active. When this occurs, the device power states are set according to their configuration in CMOS.

Note that the APM interface prevents the system from entering

SUSPEND mode directly. These modes are entered, but that occurs through the APM interface (INT15h) at the request of the APM driver.

SUSPEND mode is the lowest power state that the system can attain while still powered. The system enters the SUSPEND state when the

RESUME switch is turned off. All controllable devices are powered down and the CPU halts. In the SUSPEND state, an IRQ event including a timer tick will cause the CPU to resume from halt. If the CPU determines that the only cause of resume was the IRQ event from the timer tick, then the CPU halts again. Otherwise, the CPU resumes from the SUSPEND state. The devices which are powered ON when the system RESUMEs are specified in CMOS, loaded from the .PMI file.

Devices which do not have associated access SMIs, must be powered up.

In addition, since the CPU was stopped, the system time must be updated. If an APM driver is operating, it has the responsibility of updating the time when notified to do so. Otherwise, the firmware will update the DOS compatible system time if configured to do so. For operating systems with DOS compatible system clocks, this function should be disabled in CMOS. Since the clock does not run in SUSPEND mode and the system is not restarted by IRQ0 to maintain the time of day, the time must be reset when the system resumes. The BIOS can read the actual time from the real time clock and restore the operating system’s timer from that value. The time update can be enabled or disabled using the SETUP program. In SETUP, the option initiating the

SUSPEND/RESUME with system activities, is available.

18-3


Initiating the SUSPEND/RESUME option with system activities

1. In SETUP and in a .PMI file, enable power management and select the following options:

SETUP:

Power management:

Time updated after suspend:

ENABLED

ENABLED

2. Create a .PMI file such as TEST.PMI. Include the following commands in the TEST.PMI file:

TEST.PMI file: pmi enable=Y suspend delay=5

Enables the power management

SUSPEND after 5 minutes of idling

Note

The qualified activities to prevent the system from entering the SUS-

PEND mode are keyboard, video, hard disk, printer, COM ports, floppy drive, IRQs, and DRQs.

3. Specify the devices to be powered down in SUSPEND mode by entering the commands below: suspend hdd=Y suspend fdd=Y suspend COM2=Y

Powers down the hard disk

Powers down the floppy disk

Powers down COM2

4. Specify the events to resume the system from SUSPEND mode.

keyboard resume=Y com1 resume=Y

Resumes the system from SUSPEND mode

Resumes the system from SUSPEND mode

Note

The qualified activities to resume the system from SUSPEND mode are keyboard, video, hard disk, printer, real time clock, DRQs, COM ports, and IN accesses (interrupts related to input devices).

5. When the real time clock is used to initiate RESUME from SUSPEND, enter: rtc resume=Y Resumes the real time clock from the SUSPEND mode

An example program named WAKEIRQ8 is included in the

\EXAMPLES directory on the PC Microcontroller utility disk. This program powers the CMOS clock to generate an IRQ8 after a 30-second delay. During the delay, the system halts. After 30 seconds, the system resumes from SUSPEND.

6. Load the .PMI file changes by including the .PMI file on the PMISETUP command line. PMISETUP is located in the \UTILS directory:

C:\> PMISETUP TEST.PMI

7. Hardware reset the system for the PMISETUP options to take effect.

The system is now under power management and is ready for

SUSPEND/RESUME.

18-4


8. Once the system enters the SUSPEND mode, specified devices are powered down. Triggering the specified events will cause the system to resume.

≡

Power management configuration

The power management functions can be globally enabled or disabled in

CMOS. The 60xx SETUP.EXE and PMISETUP.EXE utilities provide an option for enabling or disabling power management.

Enabling power management

Whichever utility, SETUP or PMISETUP, is configured and saved (or loaded) last, that configuration is used for enabling or disabling power management. In other words, if the power management option is disabled in SETUP and then later a .PMI file which shows pmi enable = Y is loaded with PMISETUP, the power management option in SETUP will now show power management as being enabled.

In 60xx SETUP, the power management options can be enabled or disabled. The fine-tuning of the power management is done through a

PMISETUP with a .PMI file. All supported options are described in the subsequent sections and are represented by the | symbol. For example,

“pmi enable = YES | NO” can either mean “pmi enable = YES” or “pmi enable = NO” as the valid settings. In abbreviated terms, “Y” is also accepted for “YES” and “N” for “NO”.

In 60xx SETUP, the following options are available: n Power management n Time updated after suspend:

ENABLED | DISABLED

ENABLED | DISABLED

In PMISETUP, the following options are available: n pmi enable=Y|N

Enables/disables the power management n Time updated after suspend=YES|NO

Enables or disables the time updated after suspend

System timers

The system timers define the delays associated with power state transitions in the system. In addition to full on, only one managed system power mode is supported, the SUSPEND mode. It is possible to configure the suspend delay timer so that when the timer expires, the system will enter the SUSPEND mode. There is also an individual timer for hard disk power management. These timer settings are configured in the .PMI file of the PMISETUP program as follows:

18-5

CPU power management 6000 Series user’s manual suspend delay=xx Sets delay time before system SUSPENDs

(xx=0-31 minutes) hdd delay=xx Sets delay time before hard drive suspends, xx=0-31 minutes

IDLE timer resets

The IDLE timer monitors system activity to prevent the system from entering SUSPEND mode if bus activity indicates that the system is busy. Access to these devices will also cause the system to RESUME from SUSPEND mode. The bus activities that are monitored are configured in a .PMI file: keyboard reset idle=Y|N Enables reset of IDLE timer if Keyboard access occurs video reset idle=Y|N Enables reset of IDLE timer if Video access occurs

HDD reset idle=Y|N

IRQ reset idle=Y|N

Enables reset of IDLE timer if Hard Disk

Drive access occurs

Enables reset of IDLE timer if IRQ access occurs

LPT reset idle=Y|N

COM reset idle=Y|N

DRQ reset idle=Y|N

Enables reset of IDLE timer if LPT access occurs

Enables reset of IDLE timer if COM access occurs

Enables reset of IDLE timer if Floppy Disk

Drive access occurs

Enables reset of IDLE timer if DRQ access occurs

Interrupts in the system can also reset the IDLE timer to prevent entry into reduced power modes. These interrupts should be enabled to reset the IDLE timer if they indicate that the system is active. The interrupts to reset the IDLE timer are configured in a .PMI file: irq0 reset idle=Y|N irq1 reset idle=Y|N

Enables reset of IDLE clock if IRQ0 occurs

Enables reset of IDLE clock if IRQ1 occurs irqnmi reset idle=Y|N Enables reset of IDLE clock if IRQNMI occurs irq3 reset idle=Y|N Enables reset of IDLE clock if IRQ3 occurs irq4 reset idle=Y|N irq5 reset idle=Y|N irq6 reset idle=Y|N irq7 reset idle=Y|N




Enables reset of IDLE clock if IRQ7 occurs irq8 reset idle=Y|N irq9 reset idle=Y|N irq10 reset idle=Y|N irq11 reset idle=Y|N irq12 reset idle=Y|N irq13 reset idle=Y|N irq14 reset idle=Y|N irq15 reset idle=Y|N









18-6


If DRQ reset idle is set to YES, then the following DRQ options are specified.

drq0 reset idle=Y|N drq1 reset idle=Y|N drq2 reset idle=Y|N drq3 reset idle=Y|N drq5 reset idle=Y|N drq6 reset idle=Y|N drq7 reset idle=Y|N

Enables reset of IDLE clock if DRQ0 occurs







Suspended devices in SUSPEND mode

Certain devices need to be powered down while the system is in the

SUSPEND mode. These devices are configured in the .PMI file of the

PMISETUP program.

suspend HDD=Y|N suspend FDD=Y|N suspend LPT=Y|N suspend VIDEO=Y|N suspend COM1=Y|N suspend COM2=Y|N suspend COM3=Y|N suspend COM4=Y|N suspend SIO=Y|N

Making copies of SSD0’s contents for other boards

To copy an SSD for other PC Microcontroller boards, you must make an image of the SSD by doing the following:

1. Enter:

GETIMG SSD0

filename

2. Transfer filename to the new board.

3. Enter:

PGMIMG

filename SSD0

Note

Flash memory should be the same size and type.

To program a new BIOS into SSD0, issue the following command:

PGMBIOS

filename SSD0

To make your PICO FA drives before the hard drive (to allow you to boot from SSD), issue the following command:

SETSSD SSD0 /BEFORE

In order to make hard drives first and SSDs second, issue the following command:

SETSSD SSD0 /AFTER

For more information, see the SETSSD section in the Setup programs chapter.

Introduction

All PC Microcontrollers in the 6000 Series are programmable in

CAMBASIC™—Octagon’s version of an industrial programming language specifically designed for embedded applications. CAMBASIC is a data acquisition and an industrial control language which is easyto-use, fast, and multitasking. CAMBASIC has the ability to communicate directly to all on-card I/O including digital, analog, timing, and interrupt. This eliminates the need to write hardware drivers which means you can spend your time writing the applications software.

CAMBASIC is optimized for a 32-bit processor and supports 133

QuickBASIC compatible commands. CAMBASIC’s industrial power comes from the 93 additional commands contained in this language.

CAMBASIC’s major strengths include an extensive vocabulary of industrial BASIC commands along with a list of built-in help messages which makes the language self-documenting. Since the language is syntax compatible with languages like Microsoft QuickBASIC, there is no need for professional programmers. If you have any experience in writing

BASIC programs, you are already considered an expert in the CAM-

BASIC language. Even if you have not had any previous programming experience, there are dozens of books that can teach you to program in

BASIC.

≡

Major features

Below are the descriptions of the major features found in the

CAMBASIC language.

Event Multitasking™

CAMBASIC uses Event Multitasking™—an efficient method that compiles tasks to machine code for fast assembly operation.

During the execution of the main program, all tasks are sampled in the background at 160 times per second. Depending upon the command, the CPU type and speed, the foreground program speed ranges from 5000 to 50,000 commands per second. For example, with 32 tasks activated, the background task checking rate translates to approximately 10,000 tasks per second.

20-1

CAMBASIC 6000 Series user’s manual

CAMBASIC task types

Event Multitasking lets you do a number of system tasks in the background while you execute your program. The following tasks are available in CAMBASIC: n Calling subroutines every 0.01 to 655 seconds

Note

Use ON TICKA and ON TICKB statements to call subroutines.

n 8 counters with an interrupt on a present count n 8 programmable timed outputs n 8 interrupts on changes in digital inputs n Keypad scanning and debounce n Capturing serial input without slowing or stopping the program n Printing data without slowing the program.

Easy-to-write programs

CAMBASIC is termed as the “no hassle” embedded language. It only takes four simple steps to write the program and much less time than C.

1. At the C:> prompt, type CAMBASIC.

2. Write your program. CAMBASIC comes with several programming examples.

3. Debug your program.

4. Type SAVE name.

Keyboard mode to debug hardware

The immediate keyboard mode used to examine system components and wiring hardware can quicken system debugging. The BIT command can be used to turn on and off motors, relays, etc. Even if C or another language is used for the applications program, CAMBASIC is always in flash and remains a fast and useful tool to validate correct system operation.

Built-in help and error messages

CAMBASIC has built-in help messages for pin-pointing problems. For example, when an error occurs in a user program, the syntax of the command that caused the error is displayed.

20-2


Industrial commands

CAMBASIC has more than 93 commands, many of which are tailored to the industrial environment. CAMBASIC can do the following: n Read switch inputs individually or in groups n Write to lamps, relays, and opto-isolator modules one at a time or in groups n Write analog data to motor controllers, linear actuators, and linear indicators n Read analog data from pressure transducers, RTDs, thermocouples, and strain gauges n Send position and velocity profile information to smart motion control cards n Measure elapsed time and frequency and generate frequency outputs.

Downloading programs remotely

Programs in CAMBASIC can be written and changed via the communication serial ports. Even the built-in text editor is designed to operate over a serial link. A system can be reprogrammed thousands of miles away with the addition of a modem or radio link. You can also perform immediate mode commands to exercise equipment and verify operation from any distance.

Network support

CAMBASIC supports RS-485 networking with direct access to the BIOS network kernel in which 32 systems may be networked at the same time. CAMBASIC has several commands to link directly to the BIOS kernel to receive and send operation codes and packets of data.

Compatibility with other programs

Using the CALL or CALL ABSOLUTE commands to access other programs, CAMBASIC lets you combine it with C, assembly, or any compiled language. Since entry and exit conditions are well defined, few limitations are placed on the called programs.

Industrial extensions of CAMBASIC

In addition to the list of industrial commands, there is also a list of industrial extensions supported by CAMBASIC:

Chapter 22:

Troubleshooting

If your system is not working properly, check the following items.

No screen activity–checking console serial communications

If you do not get the sign-on message after bootup, check the following: n Make sure all cards except the PC Microcontroller are removed from the card cage. This ensures that other cards are not interacting with the PC Microcontroller and that a video card is not installed.

n Remove the jumper from the “S” position at W1.

n The VTC-9F serial cable turns the PC Microcontroller serial port into a 9-pin AT serial port. Make sure a null modem adapter is installed on the other end, and that the assembly is inserted into the proper serial port on the PC. Make sure the VTC-9F serial cable is connected to COM1 on the PC Microcontroller.

n Make sure your power module provides +5V (+/-0.20V) and at least

2.5A of current.

n After verifying the above conditions, you can monitor voltage levels by connecting an oscilloscope between the TxD* line on COM1 and ground. After powerup, you should see a burst of activity on the oscilloscope screen. The voltage level should switch between +/-8V.

Garbled console screen activity

If you do get activity on your console screen but the message is garbled, check the following: n Remove the jumper from the “S” position at W1 to force 9600, N, 8, 1 for COM1.

n If you are using PC SmartLINK, make sure you have configured the software for 9600 baud and have selected the correct serial port for communicating with your PC. Refer to the PC SmartLINK manual for information on selecting the baud rate.

n If you are using communications software other than

PC SmartLINK, Octagon cannot guarantee the operation. Make sure that the software parameters are set to match those of the PC

Microcontroller: 9600 baud, 8 bits, 1 stop bit, and no parity.

22-1

Troubleshooting 6000 Series user’s manual

System generates a BIOS message but locks up when booting from SSD0

1. Remove the jumper from the “S” position at W1 and reboot. When PICO

FA prompts you, select SSD0 as the first drive and SSD2 as the second drive.

2. Display the directory of SSD0 and verify that all the necessary boot files exist. Copy any missing files to SSD0.

3. If no files are missing, remake SSD0 to overwrite any files which may have become corrupted. In addition, you may want to do a PFORMAT and SYS to SSD0.

PICO FA reports a drive, but issuing a DIR generates an error message

1. The SSD may not be formatted. Run either of the following:

PFORMAT H

n or

PFORMAT H

n /m where n represents the hard drive number.

For more information, see the Save and run programs chapter.

PICO FA does not report the drive

1. Run SETSSD and make sure it is correct.

2. Make sure that the “X” position at W1 is jumpered or that PICOFA.SYS

is in your CONFIG.SYS file of your floppy hard drive.

3. Install a jumper on the “S” position at W1.

4. Reboot your system.

System locks up on powerup; may or may not respond to reset switch

A common cause is using a non-Octagon power supply such as a PC desktop supply. Most of these PC supplies are rated at 5V at 20A or more. Switching supplies usually requires a 20% load to operate properly, that is, 4A or more. Since a typical Micro PC system takes less than 2A, the supply does not regulate properly. Output drift up to 6-7V and/or 7-8 voltage spikes have been reported. If the power supply comes up slowly (that is, longer than 50 ms), the sequencing of ICs on the board may be out of sync, thus, causing the system to lock up.

22-2

6000 Series user’s manual Troubleshooting

Octagon supplies are designed to ramp up fast (less than 50 ms), discharge fast on powerdown and to regulate properly under a no load condition.

System locks up after powerdown/powerup

If the power supply does not drain below 0.7V, the CMOS components on the card will act like diodes and forward bias. This is typically caused by using power supplies that have large output capacitors.

Either use a different power supply that discharges faster, leave the power off until the supply has adequate time to discharge or place a

100 ohm, large wattage resistor across the output capacitor.

Octagon supplies are designed to ramp up fast (less than 50 ms), discharge fast on powerdown and to regulate properly under a no load condition.

Technical assistance

Carefully recheck your system before calling Technical Support. Run as many tests as possible; the more information you can provide, the easier it will be for the Technical Support staff to help you solve the problem.
