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 customer–

induced, 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.

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.

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.

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.

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.

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.

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 powerup. This type of failure is typical on serial interface

chips but can apply 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 Octagon Systems cards that has sufficient

current capacity, line and load regulation, hold up time, current

limiting, and minimum ripple. It is extremely import to select a

supply that ramps up in 10ms or less. This assures that all the

circuitry on the CPU cards 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 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.

phone jack. The Ethernet controller IC chip provides the following:

8K x 16 SRAM buffer

Integrated 10 Base–T transceiver interface

Two LEDs for link and traffic status integrated into the connector

Chapter 2: Installation

The 5445/5445E card requires one slot in a Micro PC card cage. Any

slot in the card cage will work. The card plugs directly into the

backplane.

≡Hardware installation

WARNING!

The 5445/5445E card contains static-sensitive CMOS

components. The card is most susceptible to damage

when it is plugged into another card. The card becomes

charged by the user and the static discharges to the

system. To avoid damaging your card and its components:

Ground yourself before handling the card

Disconnect power before removing or inserting the

card.

WARNING!

Take care to correctly position the 5445/5445E card onto

the card slot that it is being installed into.

WARNING!

Octagon assumes no responsibility caused to flat panel

displays and/or Micro PC video cards if the display is

connected incorrectly.

Using a Micro PC card cage

To install the 5445/5445E card in a Micro PC card cage, you will need

the following equipment (or equivalent):

5445/5445E Video / Ethernet card

Micro PC card cage (5xxx Card Cage)

Power module (510x or 71xx Power Module)

Octagon CPU card with a Micro PC interface

VGA compatible monitor with cable

PC SmartLINK

2. Attach the Octagon power module to the card cage following the

instructions supplied with the power module.

3. Make sure power to the card cage is OFF.

4. Slide the 5445/5445E card into the card cage. The components on the

card should face away from the power supply. See Figure 2–3 for an

illustration of the card in a Micro PC card cage.

Figure 2–3 Populated Micro PC card cage

WARNING!

Plugging in the card incorrectly will destroy the card!

5. Power on the system.

≡Connecting the monitor/display

The 5445/5445E supports both a CRT monitor and a flat panel

display. The program SM.COM allows you to display from the

monitor and some types of flat panels simultaneously. These

programs are found on the Octagon Expansion and Accessories CD

along with other diagnostic and configuration utilities. The

5445/5445E supports full-time simultaneous operation.

The 5445/5445E is factory configured and programmed with a

VGA/SVGA analog monitor driver in the on-card BIOS. If you are

using a different monitor or a flat panel display, you must reprogram

the video BIOS for the appropriate display (see “Programming the

5445 EEPROM”).

Analog Monitor

1. The CRT connector, J2, interfaces to a standard SVGA monitor.

2. Make sure the BIOS jumper is enabled — W1[1–2].

3. Configure and program your Octagon CPU card for use with a

video card and monitor. Refer to your Octagon CPU card user’s

manual.

4. Boot your Micro PC system.

5. A BIOS message similar to the following should appear on your

video monitor:

Octagon xxxx BIOS vers x.xx

Flat Panel Display

Flat panel displays use either 3V or 5V power. A jumper on the card

sets the voltage interface level to match the panel voltage level. Also,

some flat panels require a bias voltage. The 5445/5445E bias voltage

is adjustable from +19V to +30VDC. The bias voltage must be set prior

to connecting the display. A video BIOS for the panel must already be

programmed in the EEPROM display (see “Programming the 5445

EEPROM”).

The following jumpers are used to configure flat panel displays:

W2, W3, W11 and W12 – LCD bias polarity select

W4 – +3V or +5V flat panel interface voltage select

W5 – SHIFTCLK polarity select

W6 – 5V or 12V safe select

W10 – LCD bias2 select

Refer to Tables A–4 through A–9 for the jumper settings for all these

options.

1. Set the jumper at W4 for your display; either 3V or 5V (see figure

2–1 for the locations).

Table 2–1 W4 – +3V / +5V flat panel interface voltage select

Pins Jumpered Description

[1-2] 3V flat panel

[2-3] * 5V flat panel

* default

WARNING!

Selecting the incorrect voltage could damage your display.

2. Power on the 5445/5445E and measure Vee between J1, pin 25

(Vee) and pin 2 (gnd). Adjust R3 to the correct bias voltage for your

display.

Note Without a flat panel BIOS programmed into the EEPROM and

W1[1–2] jumper installed, Vee will not come up.

3. Power off the 5445/5445E and connect the flat panel display to the

J1 connector using a 50–position IDC connector with custom

wiring. The Octagon Accessories and Expansion CD contains

wiring diagrams for some of the displays. Table A–10 shows the

pinout for connector J1.

4. Make sure the BIOS jumper is enabled — W1[1–2].

5. Configure and program your Octagon CPU card for use with a

video card and monitor. Refer to your Octagon CPU card user’s

manual.

6. Power on your Micro PC System.

7. A BIOS message similar to the following should appear on your

display:

Octagon xxx BIOS vers x.xx

8. Due to loading of the Vee source, the Vee voltage will probably

require additional adjustments at this time in order to obtain

proper contrast. With the power on, re-measure Vee at J1 pin 25

and adjust R3 for the correct voltage.

Programming the 5445 EEPROM

The 5445/5445E card is factory configured and programmed to support

a standard VGA/SVGA monitor. If you are using the default monitor

and have not previously reprogrammed the 5445/5445E, skip this

section.

If you are installing the 5445/5445E in a Micro PC system and are

using a monitor/display other than VGA/SVGA, read the following

instructions. Programming the 5445/5445E requires that you boot the

Octagon CPU card from the BIOS drive, and establish a serial

communications link between your PC and the Octagon CPU card.

The following instructions assume you are using the 5445/5445E in a

Micro PC system.

1. Make sure power to the 5445/5445E is off.

2. Move the W1 jumper to position [2–3]. This disables the BIOS on

the 5445/5445E and allows you to use the serial port on your

Octagon CPU card.

Table 2–2 W1 – BIOS enable/disable jumper

Pins Jumpered Description

[1-2]* Enables the video BIOS

[2-3] Disables the video BIOS

* default

3. Start PC SmartLINK.

Note Disable any shadowing in the Octagon CPU card SETUP program.

4. Power on the Micro PC system. The Octagon CPU card logon

message should display on your PC monitor.

5. Download the file, PGMVIDEO.EXE, and the *.DAT file for your

display (e.g., 5445SM.DAT) to your Octagon CPU card. Refer to

your Octagon CPU card user’s manual for detailed information on

downloading files to the Octagon CPU card using the TRANSFER

program.

Note Do not power off the 5445/5445E when changing the W1 jumper

settings.

6. Move the W1 jumper to position [1–2]. This enables the

5445/5445E BIOS.

7. To program the 5445/5445E for the appropriate monitor/display,

type the following:

<drive>:PGMVIDEO <drive>:5445SM.DAT

The <drive> designator is the read/write drive where you transferred

the files from your PC. The *.DAT file should be changed to reflect the

type of display you are using.

8. Enter 'Y' when asked if you want to proceed. The program

PGMVIDEO then updates the video BIOS on the 5445. The

system displays a message similar to the following:

Video BIOS programming utility

------------------------------------------------

You must reboot after running this program.

Make sure the jumper labeled EN–DIS is at the EN

position.

Do you want to continue? (Y/[N])

Programming...Please wait..................

Verifying...Please wait....................

PGMVIDEO completed.

9. Power off the 5445/5445E and install your monitor/display.

≡Ethernet

Refer to Figure 2–1 for the location of various connectors.

The 5445E Video / Ethernet card provides a 10Base–T Ethernet port

and supports the IEEE 802.3 Ethernet standard. The Ethernet

controller IC chip provides the following:

8K x 16 SRAM buffer

Integrated 10 Base–T transceiver interface

The 5445E card uses twisted–pair wiring cable, which is built in a star

configuration. The interface terminates at the standard, 8–position,

RJ–45 latching phone jack.

Note There cannot be more than one Ethernet port in the Micro PC system.

IRQs

IRQ3, IRQ4, and IRQ5 connect directly to the bus. IRQ10 and IRQ11

can be routed to bus IRQ3 through jumper W8.
