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.

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.

Chapter 1: Overview

Description

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

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



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 oncard 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.

2060 CPU Card high-density and custom cables

The 2060 CPU Card has two 80-pin connectors that provide an interface for several of the card functions. Octagon has two high-density cables that break out these connectors into industry-standard interfaces. There are also four custom cables that provide connectivity for some of the functions.

Connector J2, on the front side of the board, uses the HDC-18-SBC-Multiport-2060 Interface Cable, part #6387. This cable provides an interface for LPT, COM1 and COM2, Digital I/O, USB1, Speaker, Keyboard, Mouse, AT Battery, and Reset. The LPT connector can also be used as a floppy drive connector.

Connector J500, on the backside of the board, uses the HDC-18-HDD/FP-2060 cable, part #6386. This cable provides two hard drive connectors, a flat panel connector, and USB2. Note that the hard drive connectors do not provide power to the drives. Table 2–3 and figure 2–4 show the HDD/FP cable, while table 2–4 and figure 2–5 show the Multiport cable.

Hardware mounting

1. Use the standoffs, washers, and screws and place them in the four holes on the 2060 board. Refer to Figure 2–3 for the center-to-center mounting hole dimensions and for the location of the designated holes used for mounting the hardware.

WARNING!

All four standoffs, screws and washers must be used to secure the

2060. The standoffs ensure full support of the board.

WARNING!

Verify that the washers and standoffs do not touch any of the component pads adjacent to the mounting holes. Damage will occur at power-up.

2. Connect a 5V power source to the 2060. Refer to the Power Supply Requirements section, page Refer to Figure 2–6 and Table 2–5.

30. The power supply connector is located at J3.

Make sure the power supply is OFF when connecting the power cable to the 2060 CPU Card board. Damage to the 2060 CPU Card may occur if the power is ON when connecting the power cable.

Note The +12V and –12V signals are routed to the PC/104 bus only.

Note See Appendix A – Connectors for additional mating information.

Accidentally crossing the wires, i.e., plugging +5V wires into the ground connector or the ground wires into the +5V connector will damage the 2060.

2060 CPU Card power supply requirements

The 2060 CPU Card is designed to operate from a single +5 VDC supply, connected at J3. The typical current requirements for the 2060 CPU Card is listed in the Technical data appendix. If you are using the PC/104 interface, you may also require +12 VDC.

The user should consider factors such as the power cable conductor gauge, number and length of conductors, mating connectors, and the power requirements of external devices such as hard drives, floppy drives, displays, mouse, and keyboard.

It is important that a quality power supply be used 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 ensures that all the circuitry on the 2060 CPU Card sequences properly and avoids system lockup.

Also, select a power supply that discharges quickly. If large power supply output capacitors are used, powering the system down and then up may lock up the 2060 CPU Card. If the power supply does not drain below 0.7V, the CMOS components on the 2060 CPU Card will act like diodes and forward bias, potentially damaging the 2060 CPU Card circuitry.

The proper selection of a quality power supply ensures reliability and proper functioning of the 2060 CPU Card.

Connecting a monitor and keyboard

Figure 2–7 shows the 2060 CPU Card with a monitor and keyboard. The following sections describe how to connect these items.

The 2060 CPU Card accepts an AT style keyboard and has a PS/2 type connector, located on the HDC-18-SBC-Multiport cable. The mouse port is also on the HDC18-SBC-Multiport cable, with a PS/2 type connector.

Speaker

The HDC-18-SBC-Multiport cable contains a PC speaker.

Installing an operating system

The 2060 CPU Card does not come with an installed operating system. You can install an operating system onto a hard drive or CompactFlash. Octagon Systems has software development kits available for Windows CE.net, Linux, QNX, and ROMDOS 7.1. These kits directly support the unique features of Octagon products, such as digital I/O, watchdog timer, etc., eliminating the need to write special drivers. Other software kits may also be available. Contact Octagon Systems for information concerning the software development kits.

To install an operating system you will need:

Chapter 3: Setup programs

This chapter discusses running the Setup configuration program on the 2060 CPU Card. Setup configures devices set up by the BIOS such as serial ports, floppy drives, etc.

Operating systems other than DOS

If you are using an operating system other than DOS the X jumper should be removed. The X jumper maps the INT17 extended BIOS into the 0xD80000xDFFFF memory. This can cause problems with applications or hardware running on other operating systems if they attempt to use this memory range. Removing the X jumper frees this memory for use by other operating systems.

Setup

Setup can be entered by pressing the “F2” key during the BIOS POST sequence (this occurs between the memory test and boot).

Also, by removing the “S” jumper W1[1–2], you will force the setup to revert to the factory programmed defaults shown in the following menus. This allows the user to reconfigure the setup.

Note The Setup defaults might vary slightly from those shown in the following menus

depending on the BIOS revision on your card.

The system will display the 2060 CPU Card PhoenixBIOS Setup Utility Main menu. Select the submenu by using the up/down arrows, then press <ENTER> (when using a monitor connected to the 2060 CPU Card). For a serial console configuration, Ctrl + E is up and Ctrl + X is down.

Chapter 4: Save and run programs

Save and run your programs on the 2060 CPU Card

Once you have written, tested and debugged your application, you can then save it to a device such as CompactFlash or hard drive. When you reboot the 2060 CPU Card, your program can automatically load and execute.

This chapter describes the following:

Saving an application program to hard disk or CompactFlash



Autoexecuting the program from the 2060 CPU Card



Overriding autoexecution of your program.



The examples in this chapter are for ROM–DOS – the procedures will vary for different operating systems. Some Microsoft programs make undocumented DOS calls. With ROM–DOS, an error returns when an undocumented DOS call is made, causing your program to operate erratically. We recommend using Microsoft’s MSDOS when using programs with undocumented DOS calls.

Saving programs and support files

A disk drive or CompactFlash must contain proper formatting. To format the CompactFlash or to add your own operating system, please refer to the Compact Flash, SDRAM, and battery backup chapter.

WARNING!

Reformatting the CompactFlash requires the use of a floppy, hard drive, or R/W CD-ROM to restore system files.

Adding your application

1. To add your application to your CompactFlash use the DOS COPY command

2. Add or remove any device drivers for your application. You may want to do the same for the CONFIG.SYS file on the CompactFlash. Remember to add these drivers to your drive as well.

3. To autoexecute your application, add your application name to the AUTOEXEC.BAT file.

Overriding the autoexecution of your application

You may stop the autoexecution of your application by doing one of the following options:

Option 1

1. Press F5 or F8 on your local keyboard. For more information, see your ROM– DOS manual. Note that this option does not work if you are using a terminal emulator (serial console).

Option 2

1. Press Ctrl–C when the system is first starting. This halts all batch files.

2. Change AUTOEXEC.BAT and/or CONFIG.SYS to not call out your program.

Option 3

1. Install a floppy.

2. Change Setup option “Boot Order” to “Boot 1

3. Change Setup to enable the floppy.

4. Boot from floppy.

5. Change AUTOEXEC.BAT on C:.

: Drive A:”.

Option 4

1. Remove CompactFlash from target system.

2. Install CompactFlash in host system CompactFlash adapter.

3. Edit Config.sys and/or Autoexec.bat.

4. Reinstall CompactFlash in target system.

Mating receptacle

Use a 2060 HDC-18-SBC-Multiport cable to connect the COM ports to external serial equipment. The two COM connectors of the 2060 HDC-18-SBC-Multiport cable are DB-9 female connectors that plug directly into a 9-pin PC serial cable. See

26 and 27 for information on the 2060 HDC-18-SBC-Multiport cable. Use a

pages 2060 RS–422/485 cable for connecting RS–422 and RS–485 devices, through the J7 connector.

Figure 5–1 (following page) shows two serial devices connected to the 2060 CPU Card. It also shows the schematic for connecting RS–422 and RS–485 devices. Note that you cannot use COM2 for RS–232 and RS–422/485 at the same time.

Serial port configurations

COM1 and COM2 are 8-wire RS–232 interfaces. COM2 can also be configured in BIOS Setup for 4-wire RS–422/RS–485 interfaces. RS–422 and RS–485 use the J7 connector. Some configurations of RS–422/RS–485 also require jumpers.

The COM ports are defined in table 5–1. Tables 5–2 and 5–3 show the COM pinouts for the two COM ports as well as the pin-out for the RS–422/485 cable, and table 5–4 shows the jumper settings.

Function and use of serial ports

Mating receptacle

Use a 2060 HDC-18-SBC-Multiport cable to connect the COM ports to external serial equipment. The two COM connectors on the HDC-18-SBC-Multiport cable are DB–9 female connectors that plug directly into a 9-pin PC serial cable. See

26 and 27 for information on the 2060 HDC-18-SBC-Multiport cable. Use an

pages RS–422/485 cable for connecting RS–422 and RS–485 devices, through the J7 connector.

Note See pages

26 and 27, and Appendix A – Mating connectors for mating information.

COM1 as serial console device

You can use COM1 as a console device to communicate with another PC. For COM1 to be a serial console, the “V” video jumper W1[5–6] must be removed. See the Console devices chapter for more information.

Note When interfacing the 2060 CPU Card to your desktop PC, you must use a null

modem adapter.

COM ports as RS–232 I/O

COM1 and COM2 are 8-wire RS–232 interfaces. You can connect two serial I/O devices. COM1 is always configured as RS–232. COM2 must be enabled in BIOS Setup.

In the default configuration, the video jumper W1[5–6] is installed. This jumper automatically disables the Serial Video option in the Advance menu in Setup, and the COM1 port is available for serial I/O devices. In some instances, such as running a program on the 2060 CPU Card that will ultimately be used on another card without on-board video, you might want to remove the video jumper and still use COM1 as a COM port instead of a serial console. In this instance, you must go into Setup and set Serial Video in the Advanced menu to Disabled.

COM2 as RS–422 and RS–485 networks

COM2 can be used as RS–422 or RS–485. RS–422 and RS–485 use differential signaling to communicate between the devices on a network. Differential signal reduces the effect of environmental noise, allowing communication over distances up to 1200 meters.

The RS–422 and RS–485 receivers provide a marking condition for shorted, open, or inactive lines. Note that RTS is used differently by RS–422 and RS–485. Review the information in the following sections regarding RTS.

RS–422 is a point-to-point configuration. RS–485 is a multi-node configuration that allows up to 32 nodes on a network. COM2 can be configured in BIOS Setup as either RS–232, RS–422, or RS–485. Refer to table 5–4 on page

51 for jumper

settings for terminating an RS–422/485 network.

RS–422

RS–422 is typically a point to point configuration. RS–422 is also specified for multi-drop (party-line) applications where only one driver is connected to, and transmits on, a “bus” of up to 10 receivers. The device at the end of an RS–422 network must be terminated. The 2060 CPU Card optionally terminates with a 100 ohm resistor. Refer to Table 5–4. Figure 5–3 shows a typical RS–422 four-wire interface circuit.

The RTS signal must not be enabled by the software or the RS–422 transmitter will be disabled.

RS–485

An application may implement a node as either the “host” node or as a “remote” node in an RS–485 network. There can be as many as 32 nodes without any bus repeaters in the network. A host is referred to as the node that initiates communication; while a remote is referred to as a node that is addressed by the host.

In any given communication sequence in an RS–485 network, there can only be one host. The host is responsible for initiating communication, maintaining network registration, and providing housekeeping tasks with other nodes. Remotes, however, cannot initiate a communication. They can only respond to messages that are addressed to them from the host.

The devices at each end of an RS–485 network must be terminated. Any node located between the end points should not be terminated. The 2060 CPU Card optionally terminates with a 100 ohm resistor. Refer to Table 5–4 on page Figures 5–4 and 5–5 show typical RS–485 networks.

RS–485 uses the RTS signal to control the transmitter. RTS must be set to “1” to receive characters, and set to “0” to transmit characters.

Chapter 6: LPT1 parallel port

LPT1 parallel port

LPT1 is a multifunction parallel port, which is accessed through the multipurpose connector, J2. It supports the unidirectional standard mode, bi-directional mode, enhanced parallel port (EPP) mode, extended capabilities port (ECP) mode, as well as a floppy drive. The default I/O address for LPT1 is 378h, with the default interrupt is IRQ7. You can choose the addresses 278h or 3BCh, or interrupt IRQ5, in the 2060 CPU Card BIOS Setup utility.

If the LPT port is used for a floppy drive it cannot be used at the same time as a printer port.

Mating receptacle

Use the 2060 HDC-18-SBC-Multiport cable to connect the LPT port to external parallel equipment. The LPT connector is a DB–25 female connector which plugs directly into a 25-pin parallel cable. Table 6–1 shows the pinout for the LPT connector. Table A–12 on page

114 shows the pinout for the J2 connector.

Chapter 8: CompactFlash, SDRAM, and battery backup

Description

The 2060 CPU Card is shipped with a 512 KB SMT flash. It is soldered directly onto the PCB board. This flash contains the BIOS.

The memory socket can accept up to 256 MB capacity SO-DIMM modules.

The HDC-18-Multiport cable has a connector for an AT battery to back-up the real time clock.

CompactFlash

The CompactFlash socket supports 3.3 V devices. The CompactFlash appears to the system as an IDE device. It is automatically detected and configured as a hard drive during bootup. To configure the 2060 CPU Card to boot from a CompactFlash, refer to the following section “Creating a Bootable CompactFlash.”

The CompactFlash socket is connected to the Primary IDE channel. This channel is configured for a Master device only. Therefore, if a CompactFlash device is installed, it will show up as a Master on the Primary IDE channel. Any additional IDE devices will show up as Secondary IDE devices.

Note Octagon Systems only recommends Industrial Grade CompactFlash (NAND

technology) that implements ECC error code correction, and wear level technology.

Creating a bootable CompactFlash

A CompactFlash as shipped from the factory may or may not be formatted; even if formatted, it may or may not be bootable. The following sequence shows how to create a bootable CompactFlash, and how to configure the 2060 CPU Card to boot from the CompactFlash.

CAUTION

You must use an external drive such as a hard drive, floppy, or CD to sys the CompactFlash.

1. Create a bootable external device.

Note Octagon offers OS Embedders that include a CD boot disk for a variety of operating

systems. Contact your Octagon representative for additional information.

2. Change the boot sequence in BIOS Setup so the 2060 CPU Card boots from the external drive first. Reboot from the external device.

3. Use FDISK to create partitions on the CompactFlash. Refer to your operating system manual for the appropriate parameters for using FDISK. You might also have to refresh the MBR (Master Boot Record).

4. Reboot, using the external device.

5. Format the CompactFlash.

6. Copy your operating system from the external device to the CompactFlash.

7. Change the boot sequence in Setup so that the CompactFlash (hard drive) is first. Remove the external device and power off the 2060 CPU Card.

8. Reboot.

SDRAM

The memory socket can accept up to 256 MB capacity SO-DIMM modules using PC100 or PC133 memory sticks. Note that if the Memory Speed in BIOS Setup is set to High, you must use PC133 memory sticks.

Battery backup for real time calendar clock

An AT battery can be installed to back up the CMOS real time clock. The battery can be installed on the 2060 HDC-18-SBC-Multiport cable.

Installing an AT battery

1. Power off the 2060 CPU Card.

2. Install the 3.6V AT clock battery on the 2060 HDC-18-SBC-Multiport cable.

Chapter 9: External drives

Description

The 2060 CPU Card is compatible with any standard floppy drive, and any standard IDE hard drive that has a 16–bit IDE interface. This includes CD-ROMs, CompactFlashes, and other IDE-compatible drives. The BIOS supports all IDE devices so no additional software is needed.

UltraDMA modes are not supported directly by the 2060. These modes require an 80-pin connector, and there is no adapter available for the IDE connector used on the 2060.

Note The BIOS supports three IDE devices (which includes a CompactFlash) and two

floppy drives; however, the LPT connector will only support one floppy drive.

Floppy disk controller

The 2060 CPU Card supports a 3.5 in. or 5.25 in. floppy drive via the LPT connector on the HDC-18-Multiport cable and the connector at J2. Refer to page for the pinout of the LPT port and the LPT-to-floppy adapter cable. 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.

Note See Appendix A – Mating connectors for mating information on the floppy disk

connector.

Power requirements

You must supply power to the floppy drive through an external source. Refer to your floppy drive manual for specific instructions.

Installing a floppy disk drive

1. Power on the 2060 CPU Card. Enter Setup to set up the BIOS. You can execute this program by pressing “F2” during system bootup. Configure the LPT port for “Floppy.” The system steps you through the configuration. Also, refer to the Setup programs chapter for more information on the BIOS Setup program.

2. Disconnect power to the 2060 CPU Card.

3. Connect the HDC-18-Multiport cable to J2 on the 2060 CPU Card (see page for location of J2.

4. Connect the LPT-to-floppy adapter cable (P/N 6470) to the LPT port on the HDC-18-Multiport cable.

5. Insert the 34-pin connector on the LPT-to-floppy cable into the rear of the floppy drive. Make sure pin 1 on the cable is connected to pin 1 on the drive.

6. Connect power to the floppy drive.

Hard disk controller

The 2060 CPU Card supports three 16–bit IDE devices. Since the CompactFlash is connected to the Primary IDE channel with a dedicated IDE controller, additional IDE devices connected through J500 will show up in Setup as Secondary IDE devices (master and slave).

Standard IDE devices such as hard drives and CD-ROM drives are interfaced via 40-pin connectors on the HDC-18-HDD/FP cable installed at J500.

UltraDMA modes are not supported directly by the 2060. These modes require an 80-pin connector, and there is no adapter available for the IDE connector used on the 2060.

IDE combinations:

2 hard drives



1 hard drive and 1 CD-ROM drive



CompactFlash and either of the above combinations



Note Power is NOT supplied to the IDE device through the HDC-18-HDD/FP cable.

Master/slave designation for IDE devices

IDE devices have a jumper or a switch that designates whether the device is a master or a slave device. If only one device is connected to a port, it must be configured as a master. If two devices are connected, one must be configured as a master and one as a slave. The 2060 does not use the CS signal (Cable Select) to designate master or slave on a multi-connector cable. You can use BIOS Setup to designate either the master or the slave as a boot device.

Installing a hard drive

1. Disconnect power to the 2060 CPU Card.

2. Connect the HDC-18-HDD/FP cable to J500 on the 2060 CPU Card (see page for location of J500, and see page cable).

3. Insert the 40-pin connector on the HDC-18-HDD/FP cable into the interface connector of the hard drive. Make sure pin 1 on the cable is connected to pin 1 on the drive.

4. If you are connecting two IDE devices, ensure that one of them is configured as a master and one is configured as a slave (see previous section). If connecting one IDE device, ensure that it is configured as a master. The BIOS will not be able to detect an IDE device that is configured as a slave unless a master device is also installed.

5. Connect power to the hard drive.

6. Execute the BIOS Setup program to configure your system for a hard drive. You can execute this program by pressing “F2” during system bootup. The system steps you through the configuration. Also, refer to the Setup programs chapter for more information on the BIOS Setup program.

7. If you want to boot the system from the hard drive, you need to format the drive accordingly, and change the boot order in Setup.

Organization of banks

The digital bank has a total of 24 I/O lines. The lines are configured into three groups: ports A, B and C, each group consisting of 8 bits. Any of the lines at ports A, B or C can be configured individually as inputs or outputs.

Ports A and B are connected to a 20-pin header on the HDC-Multiport cable. Port C is connected to a 10-pin header at J6. The Digital I/O Cable (part #6394) connects to J6.

Control Register

Port addressing

Ports A, B, C and the control register are addressable. The base I/O address is fixed at 120h. Digital I/O always uses [base through base +3]. Ports A, B, C and the control register are addressable, with reference to the base address.

I/O lines pulled low

The I/O lines at ports A, B, and C are always pulled low. This allows a known state upon powerup. Note that 10K ohm resistor networks are used to configure the I/O lines as low.

Configuring and programming the I/O ports

The I/O chip has three ports with eight parallel I/O lines (bits) per port. All lines can be individually programmed as all inputs, all outputs or individually as inputs or outputs. You can alter which bits are inputs or outputs by writing a control command to the control register. 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. On powerup and software or hardware reset, all digital I/O lines are reset as inputs.

Programming the I/O

Follow these steps to program the I/O chip:

1. Configure the I/O port bit directions, either as inputs or outputs.

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

Configuring the I/O

Follow these steps to configure the I/O chip.

Note In the following examples, “base” for I/O always refers to the starting address

selected in Setup (120h default).

1. Write a “2” to the control register (base address + 3). This places the I/O chip in “direction” mode: (base address = 120h)

OUT 123h, 2 (control register, direction mode)

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

Line

X 7 X 6

X 5

X 4

X 3

X 2

X 1

X 0

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:

OUT 122h, 1Ch (00011100 binary = 1C hexadecimal)

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

OUT 123h, 1 (control register, preset mode)

4. Write a bit pattern to appear at the outputs of the desired I/O port when the I/O chip is put in “operation” mode; all input bits are unaffected.

5. Write a “3” to the control register (base register + 3). This places the I/O chip back into “operation” mode:

OUT 123h, 3 (control register, operation mode)

Writing and reading from I/O

Writing to or reading from the desired I/O port is accomplished with single program statements:

1. To write a bit pattern to the desired I/O port:

OUT 122h, FFh

All output bits of port C go high; all input bits are unaffected.

2. To read a bit pattern from the desired I/O port:

PORTC = INP(122h)

The byte read from port C is assigned to variable PORTC.

I/O output program examples

To configure ports A, B, and C as all outputs, issue the commands:

OUT 123h, 2 ‘Direction’ Mode

OUT 120h, FFh ‘PortA’

OUT 121h, FFh ‘PortB’

OUT 122h, FFh ‘PortC’

OUT 123h, 3 ‘Operation’ Mode

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

OUT 120h, FFh (portA)

OUT 121h, FFh (portB)

OUT 122h, FFh (portC)

or all “0”s after:

OUT 120h, 0 (portA)

OUT 121h, 0 (portB)

OUT 122h, 0 (portC)

I/O input program examples

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

OUT 123h, 2 ‘Direction Mode’

OUT 120h, 0

OUT 121h, FF

OUT 122h, 0

OUT 123h, 3 ‘Operation Mode’

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

PORTA = INP(120h) (port A)

PORTC = INP(122h) (port C)

Enhanced INT 17h function definitions

This section provides definitions for the following functions using the INT17 handler, I17HNDLR.EXE: Initialize I/O, Write I/O, and Read I/O.

I17HNDLR.EXE is a TSR program and is called out by the 2060 CPU Card BIOS. By default, when the “X” jumper is on, the INT17 extended BIOS is operational. If the “X” jumper is removed and DOS is the operating system, the I17HNDLR.EXE TSR can be used. Once executed, the TSR is active, but it must be executed each time the system is rebooted. Copy the I17HNDLR.EXE utility to your boot device and add it to your AUTOEXEC.BAT.

Note The INT17 functions can only be used with DOS operating systems. If you use a

different operating system, the INT17 functionality can still be used by your application but must be integrated into your software.

Chapter 11: CRTs and flat panels

Description

The video system on the 2060 CPU Card is implemented with the CS5530A companion chip. It supports CRTs and TFT flat panel displays. Displays from VGA through XVGA are supported; CGA monitors are not supported. Since the video circuitry operates on the PCI bus at the full PCI bus speed, programs like Windows execute very rapidly. The 2060 CPU Card supports 3V flat panel displays through the connector. 5V panels must be powered from an alternate source.

Standard VGA monitors with analog inputs are connected using a 2 mm VGA–12 cable (p/n 6392) connected to J5. Flat panel displays are connected using a 34-pin .100 connector on the 2060 HDD/FP cable.

Note EL panels, and quarter VGA panels are not supported.

Video features

Below is a list of standard video features installed on the 2060 CPU Card:

CRT support with resolutions to 1280 x 1024 x 16 bpp at 60 Hz



Flat panel support with the following resolutions:



640 x 480 x 24 bpp 800 x 600 x 24 bpp 1024 x 768 x 16 bpp

Support for plasma and TFT flat panel displays



3V flat panel support (5V requires alternate power source) Flat panel power sequencing

Connecting a monitor

To use a monitor or a flat panel, the Video jumper (W1[5–6]) must be installed. This is the default configuration. The 10-pin connector at J5 supports an analog VGA/SVGA/XVGA CRT color or monochrome monitor; CGA monitors are not supported. The 2 mm VGA–12 cable connects to J5 and provides an industrystandard mating connector for a CRT. Refer to figure 11–1 for a diagram of connecting a CRT, and table 11–1 for the pinout for J5.

The 2060 CPU Card supports both an analog monitor and/or a flat panel display. The CT.COM and FP.COM programs allow you to toggle between the monitor and the flat panel. If the flat panel supports simultaneous mode, the SM.COM program will allow you to display images from both the monitor and the flat panel at the same time. These programs are in the Utilities zip file along with other diagnostic and configuration utilities (see page

117). Refer to the README file.

To connect a monitor you will need the following equipment (or equivalent):

Connecting a flat panel display

Due to the varied selection of available flat panels, the 2060 CPU Card is factory configured and programmed for a VGA/SVGA/XVGA CRT monitor. If you are using a flat panel, you must reprogram the video BIOS with the appropriate flat panel driver. To reprogram your video BIOS refer to Programming the video BIOS in this chapter. Note that 3V flat panels are supported through the connector, while 5V panels require an alternate power source.

The Utilities zip file (see page

117) contains text files for each of the supported flat panels. These text files include wiring diagrams specific to individual flat panels. Refer to the specific text file associated with your flat panel to build an interface cable, and to determine the correct settings for the flat panel jumpers. Flat panel displays are connected using a 34-pin .100 connector on the HDD/FP cable.

Table 11–2 shows the pinout for the connector for flat panels.

Flat panels requiring bias voltage

Some flat panels require a bias voltage. To determine if your flat panel requires bias voltage, refer to the text file in the Utility zip file which is specific to your flat panel or refer to your flat panel information. If your flat panel requires a bias voltage, refer to the manufacturer’s documentation for procedures on supplying the proper bias voltage.

WARNING!

Since improper voltage levels can severely damage the flat panel, make sure the bias voltage is correct before the flat panel is connected to the 2060 CPU Card.

Connecting the flat panel to the 2060 CPU Card

The text files in the Utilities zip file include wiring diagrams specific to individual flat panels. Refer to the specific text file associated with your flat panel to build your cable. The maximum recommended cable length is 18 inches. Table 11–2 shows the pinout for the flat panel connector on the HDD/FP cable.

1. Ensure that the Video jumper (W1[5–6]) is installed.

2. Refer to the text file associated with your flat panel to determine the supply

voltage for your panel, and whether a bias voltage is required.

3. Connect a cable from the flat panel to the flat panel connector located on the

HDD/FP cable. Refer to Figure 11–2.

Improper wiring or connection from the flat panel to the 2060 CPU Card can damage the 2060 CPU Card and the flat panel. Verify the flat panel cable connections before connecting the cable to the 2060 CPU Card and applying power to the system.

Note See Appendix A – Connectors for mating information.

Flat Panel Display

Programming the video BIOS

The 2060 CPU Card BIOS is factory configured and programmed for a 640 x 480 CRT monitor. If you wish to use a flat panel, you must reprogram the video BIOS with the appropriate flat panel driver. To reprogram your video BIOS, load the appropriate driver from the Utilities zip file.

Note Refer to the README file for a list of the supported flat panel displays. If your

particular display is not currently listed, contact Octagon Technical Support (303– 426–4521) for assistance.

To load a new BIOS to support a different flat panel:

1. Attach a CRT monitor, a PS/2 compatible keyboard, and a floppy drive to the

2060 CPU Card.

Note If a monitor and keyboard are not available, connect the 2060 CPU Card to your PC

by using a remote serial console. Refer to the Serial Console section in the Console devices chapter.

2. Power on the 2060 CPU Card.

3. Select the correct .DAT file. Example: LQ12S31.DAT

4. Run PGMVIDEO. Example:

2060 C:\> PGMVIDEO \2060\BIOS\LQ12S31.DAT

5. Power off the 2060 CPU Card.

6. Install the flat panel cable into the HDD/FP connector and then apply power to

the system.

Additional notes on video BIOS

The video BIOS is stored in EEPROM. If this BIOS should become corrupted, you will have to reprogram it. To do so, remove the Video jumper W1[5–6] and the “S” jumper W1[1–2]. Connect a serial console to COM1 to establish communication with the 2060. Repeat the procedure above to program the video BIOS.

Chapter 12: PC/104 expansion

Description

The PC/104 connector allows you to interface expansion modules such as A/D converters, CardBus, digital I/O, serial ports, etc. Modules can be stacked to form a highly integrated control system.

Note The actual maximum number of modules in a stack is limited primarily to the

capacitive loading on the bus and the electrical noise environment. This is especially true when wide temperature operation is required. Good design practice dictates that the modules present only one load to each bus signal. Unfortunately, there are modules on the market that violate this practice by loading the bus more heavily. Typically, it is the IOW*, IOR*, MEMW*, and RSTDRV* lines. For example, if the IOW* line is routed to four ICs on the module without a buffer, then the loading is equivalent to four PC/104 modules. Stacks with three or more expansion modules should be carefully tested under all environmental conditions. If possible, query the manufacture of the expansion module regarding loading. All Octagon products present one load.

Chapter 13: USB

Description

Universal Serial Bus (USB) is a hardware interface for low-speed peripherals such as the keyboard, mouse, joystick, scanner, printer, and telephony devices. USB 1.1 has a maximum transfer rate of 12 Mbits/sec, and up to 127 devices can be attached. Peripherals can be plugged in and unplugged while power is applied to the system. The 2060 CPU Card contains two 1.1 compliant USB ports.

The two USB ports are accessed via standard USB connectors on the HDC-18Multiport Cable (USB1) and the HDD/FP cable (USB2). Any USB device can plug into either USB interface, or into a multi-port hub that then plugs into either USB port.

An operating system capable of utilizing the USB ports and USB devices is required for USB operation.

Caution

Overview: Section 3 – System management

Section 3 provides information on managing the 2060 CPU Card in the areas of internal control and troubleshooting. The following chapters are included:

Chapter 14: Watchdog timer and hardware reset

Chapter 15: Serial EEPROM

Chapter 16: CPU clock, system jumpers, user jumper, and BIOS recovery

Chapter 17: Troubleshooting

Chapter 14: Watchdog timer and hardware reset

Description

The watchdog timer is a fail-safe against program crashes or processor lockups. It has a programmable timeout period, ranging from 2.0 milliseconds to 2 minutes (see next section). The watchdog timer can be enabled or disabled in Setup. INT17 software calls, a built–in function on the 2060 CPU Card, can also be used to enable and set the timeout, extend the timeout, strobe, and disable the watchdog timer from your application. If the timer expires, it performs a hardware reset.

Timeout period (ranges)

Although the timeout periods are listed as 2.0 milliseconds to 2 minutes, the actual timeouts are ranges of ±50% of the listed values. Therefore, for a selected timeout period of 2 minutes, the timeout could expire in as little as one minute or as long as three minutes. To ensure that the watchdog does not reset the system accidentally, always strobe the watchdog at a rate of at least twice the selected timeout period.

Booting, power down, and strobing the watchdog timer

When the watchdog is enabled in Setup, it sets the timeout period for two minutes. The BIOS will strobe the watchdog during the boot process and once more just before booting is finished. The user’s application must then begin strobing. The watchdog will continue until it is disabled or power down occurs.

If the watchdog is enabled in Setup and your operating system cannot load up before the timer expires, your system could reset. Also, if you do not disable the watchdog and your strobing application ends before power down you could again reset. If these watchdog situations should occur, remove the “S” jumper W1[1−2] and reboot. This causes the 2060 to boot using Setup defaults (watchdog disabled). Enter Setup, then change and save the watchdog settings in Setup.

Watchdog function definitions using enhanced INT 17h handler

This section provides definitions for the watchdog functions using the INT17 handler (I17HNDLR.EXE). I17HNDLR.EXE is a TSR program. It is called out by the 2060 CPU Card BIOS. Once executed it is active, but it must be executed each time the system is rebooted. If you use a different BIOS the INT17 functions can still be used by your application. Copy the utility to your hard drive and add it to your AUTOEXEC.BAT.

The INT17 handler is designed for DOS based applications. If you use a different operating system and the watchdog functions are required for your application, source code is available in the Examples directory of the Utilities zip file to access the watchdog. OS Development Kits are available from Octagon for Linux, QNX, and Windows CE.net that have watchdog drivers for these operating systems. Contact Octagon Systems for more information.

Hardware reset

The HDC-18-Multiport cable has a reset switch which allows you to reset the system without turning off the power. This provides a more complete reset than the <CTRL><ALT><DEL> method. By depressing this button (connecting the two lines), the circuit is pulled to ground and resets the system.

The RESET command accomplishes the same thing as the reset button. Refer to the component diagram in the Quick start chapter for the location of the reset button.

WARNING!

When using COM1 as the console, the <CTRL><ALT> <DEL> commands on the host system keyboard only reset the host system. Use the RESET command to issue a hardware reset on the 2060 CPU Card.

Chapter 15: Serial EEPROM

Description

Up to 1024 words of user-definable data can be saved in the serial EEPROM. The serial EEPROM does not require battery backup to maintain the data when the system power is off. The serial EEPROM is easily accessible via software interrupts by most programming languages.

System jumpers

Various system function options are selected with jumper block W1.

The “S” jumper selects whether the card boots from user defined parameters (defined in the Setup Programs chapter), or the BIOS defaults. Removing this jumper allows the user to return to factory programmed defaults.

The “X” enables or disables the BIOS extension area. The default is enabled, which uses the INT17 calls.

The “V” jumper enables or disables the on-card video, allowing an external video card, or the serial console to be used.

The “U” jumper is user defined and can be used for program control.

The “R” jumper, when removed, allows the BIOS to be reinstalled from a remote system over a serial console connection.

Table 16−2 System configuration jumper: W1

System jumper

The system jumper is W1[1–2]. When this jumper is present the system boots using the parameters stored in Setup. When this jumper is removed the system boots using the factory defaults for all parameters in Setup. Note that if you must remove the system jumper to recover your system, the user-defined parameters in Setup will not be changed unless you enter Setup, make the changes, and exit saving changes.

[5–6]*

[9–10]*

Extended BIOS jumper

The extended BIOS jumper is W1[3–4]. The extended BIOS memory region (D8000h to DFFFFh) contains the Octagon INT17 functions. When this jumper is removed, this memory region is freed up for other uses. Note that if you want to use the INT17 functions, you must either leave the jumper installed or copy those functions elsewhere.

You can also modify the extended BIOS using the MAKEBIOS.BAT file, located in the 2060 Utilities zip file (see page

117). Type MAKEBIOS ? for a list of available

options.

Video jumper

The video jumper is W1[5–6]. When this jumper is installed the on-card video is enabled. To use a serial console, or an extension-card video (such as a PC/104), remove this jumper.

User jumper

The user jumper is W1[7–8] and is associated with bit 3 of the register address A10h. The INT17 functions provide an easy method to implement software routines

according to whether or not a jumper has been installed. Refer to the INT17 calls to read user jumper on page

96.

BIOS recovery jumper

The BIOS recovery jumper on the 2060 is W1[9–10]. This jumper allows you to reinstall the BIOS from a floppy disk using a serial link from COM1 of the 2060 to COM1 of a host computer. When the BIOS recovery jumper is removed, the system will use the boot block recovery process to program a new BIOS.

The BIOS recovery process uses the embflash.exe utility. This utility can be obtained from Octagon Technical Support. To use the BIOS recovery jumper the following steps must be taken:

1. Copy the EMBFLASH.EXE, PLATFORM.BIN, CLIENT.BIN, and BIOS.ROM

files to the root directory of a bootable floppy disk.

2. Remove power from the 2060.

3. Remove the W1[9–10] BIOS jumper.

4. Using a 2060 CPU Card HDC-18-SBC-Multiport cable and a null modem

adapter connect COM1 on the 2060 to COM1 on the Host computer. It does not matter what OS is on the HOST computer as long as a DOS session can be started.

5. Put the bootable floppy disk from step 1 with the embflash.exe and support

files in drive A of the host computer, and reboot the host computer from the floppy drive.

6. Power up the 2060. If you have a post card, you can place it on the 2060

PC/104 or PC/104 Plus bus and the system will boot to a post A1, or you can allow about 5 seconds for the system to boot to the boot block recovery state.

7. On the host computer type embflash<enter>. The host computer will display a

status screen that shows the progress of the BIOS programming.

8. When the status screen indicates the process is complete power down the 2060

and replace the W1[9–10] jumper. The new BIOS will now be used when the 2060 is re-started.

BIOS programming using PHLASH.EXE

The BIOS on the 2060 can be reprogrammed using the PHLASH.EXE utility. This utility is in the Utilities zip file (see page following steps must be taken:

1. Copy PHLASH.EXE, PLATFORM.BIN, and BIOS.ROM to the root of a

bootable DOS floppy disk.

2. Boot the 2060 from the DOS floppy disk with a CRT monitor or flat panel

connected to the system. Note that HIMEM.SYS cannot be used in CONFIG.SYS.

117). To program the new BIOS the

3. At the DOS prompt for the “A” drive type phlash <enter>.

The utility will display a progress screen and tell you when the process is done. You may need to push the reset button or cycle the power on the system to boot from the updated BIOS.

INT17 calls to read user jumper

The user jumper is W1[7–8]. The INT17 functions provide an easy method to implement software routines according to whether or not a jumper is installed.

Chapter 17: Troubleshooting

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

Boot Block Recovery

The 2060 CPU Card supports boot block recovery. This feature allows the user to reprogram the system BIOS over COM1 using an HDC-18-SBC-Multiport cable, a null modem adapter, a floppy disk, and a host computer. This option should only be necessary if a BIOS has been programmed into the 2060 CPU Card and is either corrupted or non-bootable. For more information covering the boot block recovery process read the Boot block recovery section in chapter 16 and call Octagon Systems Technical Support.

Memory conflicts using operating system other than DOS

No system LED activity

If there is no LED activity at CR2, check the following:

Make sure all PC/104 expansion cards are removed from the 2060 CPU Card.



This ensures that other cards are not interacting with the 2060 CPU Card.

Remove the jumper from the “S” position at W1[1–2].



Check all power connections to the 2060 CPU Card card.



Measure the supply voltage at the J7 power connector and verify that the



voltage at the 2060 CPU Card card is +5V (+/–0.25V).

Make sure your power module provides +5V (+/–0.25V) and at least 2.5A of



current.

No CRT or flat panel video

If the LEDs appear to be functioning properly, but there is no video activity, check the following:

Make sure all PC/104 expansion cards are removed from the 2060 CPU Card.



This ensures that other cards are not interacting with the 2060 CPU Card.

Remove the jumper from the “S” position at W1[1–2].



If using a CRT monitor, check the cable and connections going from the J5



connector to the monitor.

If using a flat panel display, check the following:



Cable and connections going from the HDD/FP cable to the flat panel display. Check the power and cables going to the flat panel display. Make sure that the power module has enough current capacity to power both the 2060 CPU Card card and the flat panel.

If a flat panel BIOS has been programmed into the 2060 CPU Card that is



incorrect for the flat panel being used and an analog monitor is not present or is not displaying the video data correctly, the system can be booted via the serial console by doing the following:

1. Remove the “S” and the “V” jumper.

2. Connect the COM port of a host computer running HyperTerminal or some other terminal software to COM1 on the 2060 CPU Card using an HDC-18SBC-Multiport and a null modem adapter. The serial port settings on the host computer should be 38.4K baud, 8, N, and none.

3. Power up the 2060 CPU Card, it will boot using the serial console interface. Once the system has successfully booted you can use the pgmvideo.exe utility to either program the desired flat panel VIDEO BIOS into the 2060 CPU Card or program in the CRT.DAT file for analog monitor support to recover the system.

4. Replace the “S” and “V” jumpers and re-boot the system.

Video is present but is distorted

If video is present but is distorted, check the following:

Make sure all PC/104 expansion cards are removed from the 2060 CPU Card.



This ensures that other cards are not interacting with the 2060 CPU Card.

Remove the jumper from the “S” position at W1[1–2].



If using a CRT monitor, check the cable and connections going from the J5



connector to the monitor.

If using a flat panel display, check the following:



1. Cable and connections going from the HDD/FP cable to the flat panel display

2. Signal cable going to the flat panel display. If the cable length is too long, the distortion may be caused by noise. 18” or less is the recommended length. Cable shielding may be required.

3. Power cable going to the flat panel display.

4. Power module for the flat panel. Make sure that the power module has enough current capacity to power both the 2060 CPU Card and the flat panel.

No serial console activity

If the serial console does not appear to be functioning correctly, check the following:

Make sure all PC/104 expansion cards are removed from the 2060 CPU Card.



This ensures that other cards are not interacting with the 2060 CPU Card.

Remove the jumper from the “S” position at W1[1–2].



Make sure the COM1 connector on the 2060 CPU Card HDC-18-SBC-



MULTIPORT cable is used.

Make sure a null modem adapter is installed between COM1 of the HDC-18-



SBC-MULTIPORT cable and the serial port of your PC.

Make sure that your terminal emulator (such as HyperTerminal) on your PC is



set up properly. Refer to the Console devices chapter. Refer to the HyperTerminal manual for information on setting up communication parameters.

After verifying the above conditions, you can monitor voltage levels by



connecting an oscilloscope between the TxD* line on COM1 and ground. After power-up, you should see a burst of activity on the oscilloscope screen. The voltage level should switch between +/–8V.

Garbled serial console screen activity

If you do get activity on your console screen but the message is garbled, check the following:

Remove the jumper from the “S” position at W1[1–2] to ensure the default



settings for COM1.

Make sure that your terminal emulator (such as HyperTerminal) on your PC is



set up properly. Refer to the Console devices chapter. Refer to the HyperTerminal manual for information on setting up communication parameters.

System generates a BIOS message but locks up when booting

Remove the jumper from the “S” position at W1[1–2] and reboot.



Verify that all the necessary boot files exist on the boot device. Copy any



missing files to the boot device.

If no files are missing, overwrite any files which may have become corrupted.



In addition, you may want to format the boot device.

System will not boot from CompactFlash

Many CompactFlash devices as shipped from the factory are not bootable devices. Refer to the CompactFlash, SDRAM, and battery backup chapter to make your CompactFlash bootable.

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

A common cause is using a non-Octagon power supply such as a PC desktop supply. Most of these PC supplies are rated at 5V at 20A or more. Switching supplies usually requires a 20% load to operate properly, that is, 4A or more. Since a typical Octagon system takes less than 2A, the supply does not regulate properly. Output drift up to 6–7V and/or 7–8 voltage spikes have been reported. If the power supply comes up slowly (that is, longer than 10 ms), the sequencing of ICs on the board may be out of sync, thus, causing the system to lock up.

Octagon supplies are designed to ramp up fast, discharge fast on power-down and to regulate properly under a no load condition.

System locks up after power-down/power-up

If the power supply does not drain below 0.7V, the CMOS components on the card will act like diodes and forward bias. This is typically caused by using power supplies that have large output capacitors. Either use a different power supply that discharges faster, leave the power off until the supply has adequate time to discharge or place a 100 ohm, large wattage resistor across the output capacitor.

Octagon supplies are designed to ramp up fast, discharge fast on power-down and to regulate properly under a no load condition.

LED signaling of “beep” codes

The 2060 CPU Card has a bicolor LED that is used by the BIOS to indicate the BIOS processing state.

Immediately after the 2060 CPU Card powers on, the amber LED is on and the green LED is off. Once the card boots, the CR5 amber LED turns off and the green LED is on.

If the BIOS finds an error during the power on self test (POST) the amber LED is flashed in a pattern indicating the POST code failure. The visual beep codes are defined in Table 17–1.

Count the number of flashes in each of four sets. Subtract one from each set, the resulting number matches the POST error found in the Table 17–1.

For example:

Flash–Flash pause

Flash–Flash–Flash–Flash pause

Flash–Flash–Flash–Flash–Flash pause

Flash–Flash–Flash–Flash

Is counted as 2–4–5–4. After subtracting one from each set the result is 1–3–4–3. This is a failure of the first 64K of base RAM.
