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 compo-

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

never

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

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

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

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

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

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

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

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

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

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

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

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.

Chapter 1:

≡ Introduction

The Octagon 6000 Series PC Microcontroller™ cards are intended for easy usage and high performance in embedded control applications.

The PC Microcontroller cards combine the best features of the PC architecture and microcontroller I/O. Bringing PC software to the microcontroller world eliminates the need to maintain development systems for the different microcontroller chips. The Octagon PC Microcontrollers operate in severe environments, providing an extra margin of reliability in any application. Although ROM-DOS™ 6.22 is included, you can download other operation systems into the flash drive. If you prefer operating in a high-level language, CAMBASIC has been built-in as a fast, easy-to-use, industrial control language.

Common features across the PC Microcontroller product line include: n Suite of embedded software

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.

Con venient 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 displa y 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 saf ety

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 CAMBASIC and C.

Overview 6000 Series user’s manual

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 sup-

plied 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 opera-

tion. 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 f or 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 resets 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 en vironmental 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.

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

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

6000 Series user’s manual Quick start

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 Microcontr oller 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 infor- mation on using TRANSFER.EXE.

Setup programs

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 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.

6000 Series user’s manual Setup programs

≡ 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.

Chapter 4:

Save and run programs

≡ Save and run your programs on the PC

Microcontroller

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

This chapter describes the following:

n Saving an application program to SSD0 n Autoexecuting the program from the PC Microcontroller n Overriding autoexecution of your program.

The information in this chapter assumes you will be using ROM-DOS in your application. Some Microsoft programs make undocumented DOS calls. With ROM-DOS, an error will be returned when an undocumented 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.

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

60xx C:\> PFORMAT H

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

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.

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 y our 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.

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”.

4. At the prompt, “PICO FA second drive (2=SSD2, other=no drive),” enter “2”.

5. At the prompt, “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:

≡ 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

6000 Series user’s manual Serial ports

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

Serial ports 6000 Series user’s manual

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 T urbo 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

6000 Series user’s manual Serial ports

PC mode/network mode

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

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

Serial ports 6000 Series user’s manual

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.

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. ;> ;message start character ; 01 ;intended listener is ID 01 ; A ;command code A (roll call) ; A3 ;checksum = uchar (‘0’+‘1’+’A’+0x01) = 0xA3 ; . ;message end character

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.

6-7

EZ I/O 6000 Series user’s manual

Table 6-7 6050 high current outputs

# of Outputs Max current per o utput

1500 mA 2410 mA 3310 mA

4260 mA 5210 mA 6190 mA 7160 mA 8150 mA

nSince 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

(To High Current Output)

n Configuring outputs in parallel for higher drive is NOT recom-

mended 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.

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 this port.

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.

Table 6-12 EZ I/O port byte

bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0 I/O line

EZ I/O p ort byte EZ I/O p ort

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

6000 Series user’s manual EZ I/O

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

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.

address, dirA, initA, dirB, initB, dirC,

Note Usually, once the chip is configures with the CONFIG EZ IO statement,

there is no reason to reconfigure this statement again

6-15

EZ I/O 6000 Series user’s manual

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 (port A) OUT 141H, 0 (port B) OUT 142H, 0 (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:

OUT 143H, 2 ‘Direction Mode’ 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.
