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.

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.

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!
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.
WARNING!

≡
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.
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.
