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 that are common to all
manufacturers of CMOS equipment.
The most common failures on CPU control 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.
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.
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.
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.
3

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.
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.
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 power–up. This type of failure is typical on
serial interface chips but can apply to any IC on the card.
Under-rated power supply: The board may fail to boot due to an under-
rated power supply. It is important that a quality power supply be used with
the 2060 CPU Card that has sufficient current capacity, line and load
regulation, hold up time, current limiting, and minimum ripple. The power
supply for the 2060 must meet the startup risetime requirements specified in
the ATX Power Design Guide, version 1.1, section 3.3.5. This assures that all
the circuitry on the CPU control card sequences properly and avoids system
lockup.
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 sub-microsecond 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 or CPU
WARNING!
When handling any Octagon Single Board Computer, extreme care
must be taken not to strike the heatsink (if installed) against another
object, such as a table edge. Also, be careful not to drop the Single
Board Computer, since this may cause damage to the heatsink or
CPU as well.
Note Any physical damage to the single board computer card is not covered under
warranty.

Excessive Thermal Stress
This card is guaranteed to operate over the published temperature ranges and
relevant conditions. However, sustained operation near the maximum temperature
specification is not recommended by Octagon or the CPU chip manufacturer due to
well known, thermal related, failure mechanisms. These failure mechanisms,
common to all silicon devices, can reduce the MTBF of the cards. Extended
operation at the lower limits of the temperature ranges has no limitations.

The 2060 PC/104 CPU Card is intended for higher-performance, low-power
embedded control applications. The 2060 CPU Card integrates serial
communications, IDE hard disk port, floppy disk support on LPT1, CompactFlash
socket, a multifunctional parallel port, digital I/O, two USB ports, keyboard, mouse
and speaker ports, and video. The 2060 CPU Card can be used in a stand-alone
mode or expanded through a PC/104 interface.
Note The 2060 is a stand-alone CPU card. It cannot be used as an expansion card on
another CPU card.
The 2060 CPU Card comes with a BIOS loaded on a flash device for easy updates.
It is fully compatible with most popular operating systems.
2060 CPU Card major hardware features
CPU processor
The CPU is a high-performance, low-power AMD Geode GX1 processor with a clock
speed of 233 or 300 MHz, jumper selectable. It uses the CS5530A companion chip
for some of the peripherals. The 2060 CPU Card has an ISA bus speed of 8.33 MHz.
SDRAM
The memory socket can accept up to 256 MB capacity SO-DIMM modules.
On-board flash
On board is a 512 KB Surface Mount (SMT) boot flash that contains the BIOS.
CompactFlash socket
The CompactFlash socket accepts a Type I or Type II CompactFlash card. The
CompactFlash appears as an IDE device to the system. It is implemented with an
ATA-4 compliant IDE controller, and appears in Setup as the Primary IDE device.

Hard disk and floppy disk ports
The hard drive is routed through an 80-pin connector on the bottom side of the
board. The Octagon 2060 HDD/FP cable breaks out 40 of the pins into two standard
40-pin IDE hard drive connectors. Note that the IDE connectors do not supply +5V
to a hard drive.
The hard drive is implemented with a second ATA-4 compliant IDE controller (the
CompactFlash uses the Primary IDE controller). The BIOS supports up to two IDE
drives in addition to the CompactFlash.
A floppy drive is supported through the LPT port. LPT is routed through an 80-pin
connector on the top side of the board. The Octagon 2060 Multiport cable breaks
out the pins into a standard 25-pin LPT port. The Octagon LPT-to-Floppy cable
connects directly into the LPT port and provides a standard 34-pin floppy drive
connector. Note that only the LPT-to-Floppy cable part # 6470 can be used with
this card, as the floppy pin out from the LPT port differs from other cards. Floppy
drive is selected as one of the options in the LPT menu of BIOS Setup.
USB ports
The CS5530A companion chip supports two USB 1.1 channels, which are available
when using an operating system that supports USB. There is no support from
Octagon for DOS legacy USB.
Both channels are open HCI compliant. USB1 is routed through the 80-pin
connector on the top side of the board. The Octagon 2060 Multiport cable breaks
out the pins into a standard USB connector. USB2 is routed through the 80-pin
connector on the bottom side of the board, and uses the Octagon 2060 HDD/FP
cable.
Note that USB devices are hot-swappable when a device is plugged into a standard
USB connector, as pins on the connectors determine the order in which they make
contact. Devices are not hot-swappable when connected to a non-standard header.
You can hot swap a device through the USB connector on the 2060 Multiport cable,
or through another USB connector wired to the 80-pin header, but you cannot hot
swap at the 80-pin header itself.
Digital I/O
The 2060 has 16 digital I/O lines on the 80-pin connector (accessed through the
2060 Multiport cable) and an additional eight lines on a separate connector. These
24 digital I/O lines will interface with logic devices, switch inputs, LEDs and
industry standard opto module racks. The I/O lines are 0–5V logic compatible.
They can be individually programmed as inputs or outputs. The 2060 Digital I/O
cable provides connection to the additional eight I/O lines.
Serial ports protected against ESD
The 2060 CPU Card has two serial ports. COM1 and COM2 provide RS–232C.
COM2 also supports RS–422 and RS–485 interfaces. COM1 and COM2 are routed
through the Octagon 2060 Multiport cable for RS–232C. RS–422 and RS–485 are
provided through a separate connector. The 2060 RS-422/485 cable provides a
14

standard COM port connector for RS–422 and RS–485.
Multifunctional printer port
The 2060 CPU Card incorporates the latest enhanced parallel port and includes
unidirectional, bi-directional, ECP, EPP, and Floppy Drive modes.
The following represent applications in the multifunctional parallel port:
LPT1 for PC compatible printers
17 general purpose digital I/O lines
Floppy disk drive port
Multipurpose connectors and cables
Most of the peripherals on the 2060 CPU Card are routed through two 80-pin
connectors. Octagon has cables that break out these 80 pins into industry standard
connectors. Because of the compact form factor of the 2060 CPU Card some
additional connectors are nonstandard, and are supported by Octagon cables. These
cables are listed below:
HDC-18-SBC-MULTIPORT-2060 interface cable Connects into J2 on the
top of the board and provides industry standard connectors for COM1, COM2,
Digital I/O, USB1, LPT1, PC battery, and PS/2 compatible keyboard and
mouse, as well as a PC speaker and a Reset switch. Part number 6387.
HDC-18-SBC-HDD/FP-2060 cable Connects into J500 on the bottom of the
board and provides a standard 40-pin hard drive connector, USB2, and a 34-pin
flat panel interface. Part number 6386.
2060 COM2 RS-422/485 Cable Connects into J7 to provide RS–422 and RS–
485 through a standard serial port interface. Part number 6393.
2060 Digital I/O Cable Connects into the optional J6 connector for eight
additional digital I/O lines. Part number 6394.
2 mm VGA-12 Cable Connects into J5 and provides a standard 15-pin
VGA interface. Part number 6392.
LPT-to-Floppy Adapter Cable Connects into the LPT port and provides a
standard 34-pin floppy drive interface. Part number 6470. Note that only the
LPT-to-Floppy cable part # 6470 can be used with this card, as the floppy pin
out from the LPT port differs from other cards.
Hardware reset
A hardware reset ensures complete reset of the system and all attached
peripherals. A hardware reset can be done by any of the following methods:
An expired watchdog timer cycle
Depressing the reset switch
Cycling power
Power supervisor reset

Video
The 2060 CPU Card supports CRT monitors up to 1280 x 1024 x 8 bpp (bits per
pixel) resolution, and flat panel displays with up to 1024 x 768 x 8 bpp resolution.
CGA monitors are not supported;
Speaker, keyboard, and mouse ports
The 2060 Multiport cable contains a PC speaker, a PS/2 keyboard connector, and a
PS/2 mouse connector. Neither the keyboard nor the mouse is required for
operation.
Real time calendar/clock with battery–backup
The real time clock is fully AT compatible. An optional off-card battery powers the
real time clock when the 5 volt supply is removed. The AT battery is connected via
the 2060 Multiport cable.
Setup information stored in EEPROM for high reliability
Loss of Setup data is serious in industrial applications. Most PCs store Setup
information in battery-backed CMOS RAM. If the battery fails or is replaced
during routine maintenance, this information is lost. Without a keyboard and
monitor in embedded applications, time consuming re-initialization is required.
The 2060 CPU Card stores the Setup information in EEPROM with 1024 words
available to the user. Software routines to use this available memory come with the
2060 CPU Card.
Watchdog timer added for safety
The watchdog timer resets the system if the program stops unexpectedly. The
watchdog is enabled, disabled and strobed under software control; it can also be
enabled or disabled in Setup. The time-out period is programmable from 2 ms to
120 seconds, with a variability of ±50%.
PC/104 interface
The PC/104 interface accepts an 8- or 16-bit PC/104 expansion board. PC/104
expansion boards are available from several manufacturers. PC/104 expansion
boards may be stacked on the PCS–620 to form a fully-integrated system.

2060 CPU Card major software features
Diagnostic software verifies system integrity automatically
The 2060 CPU Card has built-in diagnostic software that can be used to verify on-
card I/O and memory functions. On power-up, a series of tests is performed. If a
problem occurs, the failed test can be identified by a flashing LED or a beep code.
The test is performed automatically every time the system is reset or powered up.
Memory verification does not require software, test equipment, monitor, keyboard,
disks, or test fixtures. See the “Troubleshooting” chapter for a listing of tests and
failures and their descriptions.
Phoenix software BIOS
The 2060 CPU Card has a Phoenix Software BIOS with Octagon BIOS extensions.
The BIOS extensions support the INT17 functions.
Octagon BIOS extensions
On-board BIOS extensions allow easy access to watchdog timer functions, serial
EEPROM, digital I/O, etc.
Boot sequence
A 2060 CPU Card can be configured to boot from CompactFlash, a floppy disk, a
hard disk, or a CD–ROM.
