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.
The most common failures on Single Board Computers 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 single case where multiple IC failures were accident. It is very probable that multiple component failures indicate that they were user-induced.
not caused by misuse or
never found a
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.
3
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 power-up: 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 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 PC–600 SBC that has sufficient current capacity, line and load regulation, hold up time, current limiting, and minimum ripple. The power supply for the PC–600 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 CPU control 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 PC–600 Single Board Computer is intended for higher-performance embedded control applications. The PC–600 integrates serial communication, IDE hard disk port, CompactFlash socket, floppy disk port, a multifunctional parallel port, a keyboard/mouse port, a video interface, two USB ports, an audio port, two 10/100BaseT Ethernet ports, and 48 digital I/O lines. The PC–600 can be used in a stand-alone mode or expanded through a PC/104 or PC/104 Plus interface.
The PC–600 comes with a BIOS loaded on a flash device for easy updates. It is fully compatible with most popular operating systems.

PC–600 major hardware features

CPU
The CPU is a high-performance, low-power AMD Geode GX1 CPU with a maximum clock speed of 300 MHz. It uses the CS5530A companion chip for some of the peripherals. The PC–600 has an ISA bus speed of 8.33 MHz, and a PCI speed of 33 MHz.

SDRAM

The memory socket can accept up to 512 MB capacity SO-DIMM modules.

On-board flash

On board is a 512 KB SMT flash that contains the BIOS.
16

Hard disk, CompactFlash, and floppy disk ports

The IDE hard drive port is terminated with a 44-pin, 2 mm connector and supplies power to 2.5” hard drives. CompactFlash appears as an IDE device and has a locking type interface. The BIOS supports up to three IDE drives. The floppy drive port is terminated with a standard 34-pin connector and up to two floppy drives are supported.

USB ports

The CS5530A companion chip supports two USB 1.1 channels, which are available when using an operating system that supports USB. Both channels are open HCI compliant.
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 two-port USB cable, or through another USB connector wired to the 10-pin header, but you cannot hot swap at the 10-pin header itself.

Serial ports

The PC–600 has four serial ports with combinations of RS–232C, RS–422, and RS–485 interfaces.

Digital I/O

The 48 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.

Speaker, keyboard, and mouse ports

The audio connector has a speaker output, which is PC compatible. The keyboard controller accepts an AT style keyboard and has a PS/2 type connector. The mouse port is combined with the keyboard port and is accessed with a “Y” cable. Note that with some “Y” cables you may have to plug the mouse into the keyboard icon, and the keyboard into the mouse icon; if the mouse and keyboard do not function at power up, try switching them. A keyboard connects directly to the PC–600 while a mouse requires the “Y” cable.

Video

CRTs are supported up to 1280 x 1024 x 16 bits per pixel (bpp) resolution. Flat panel displays are supported up to 1024 x 768 x 16 bpp resolution.

PC/104 and PC/104 Plus interface

The PC/104 interface accepts an 8- or 16-bit PC/104 expansion board. The PC/104 Plus accepts industry-standard PC/104 Plus boards. PC/104 expansion boards are available from several manufacturers. PC/104 or PC/104-Plus expansion boards may be stacked on the PC–600 SBC to form a fully-integrated system.

Ethernet

The PC–600 provides two 10/100BaseT Ethernet ports and supports the IEEE 802.3 Ethernet standard.

Multifunctional printer port

The PC–600 incorporates the latest enhanced parallel port and includes unidirectional, bi-directional, ECP and EPP modes.
The following represent applications in the multifunctional parallel port:
LPT1 for PC compatible printers 17 general purpose digital I/O lines Up to a 4 x 4 matrix keypad 4–line alphanumeric display

Watchdog timer added for safety

The watchdog timer resets the system if the program stops unexpectedly. The watchdog is enabled, disabled, and strobed by 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%.

Real time calendar/clock with battery–backup

The real time clock is fully AT compatible and uses the standard DOS calls. An optional off-card battery powers the real time clock when the 5 volt supply is removed. A connector is provided for the external battery.
18

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 re­initialization is required. The PC–600 stores the system Setup information in nonvolatile EEPROM so that it is still available if the battery backup fails or is not used. There are 1024 words available to the user. Software routines to use this available memory come with the PC–
600.

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:
An expired watchdog timer cycle Depressing the reset switch or pulling the reset pin to ground Cycling power Power supervisor reset

Temperature sensor

A serial temperature sensor is located on the card. It is accessed through INT17 calls.

5 volt operation lowers system cost

The PC–600 operates from a single 5V ±5% supply.

PC–600 major software features

Diagnostic software verifies system integrity automatically

The PC–600 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. 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 complete listing of tests and failures and their descriptions.

Phoenix BIOS

The PC–600 has a Phoenix BIOS with Octagon BIOS extensions. The BIOS extensions support the INT17 functions.

Octagon BIOS extensions

On–board BIOS extensions allow easy access to digital I/O, watchdog timer functions, temperature sensor, etc.

Boot sequence

A PC–600 can be configured to boot from a CompactFlash, a floppy disk, a hard disk, or a CD–ROM.

Power supply requirements
The PC–600 is designed to operate from a single +5 VDC supply, connected at J9. The typical current requirements for the PC–600 is listed in the Technical data appendix. If you are using the PC/104 interfaces, you may also require +12 VDC. Make sure that you utilize both +5 VDC conductors and both ground conductors.
You should also consider other factors such as the power cable conductor gauge, number and length of conductors, mating connectors, and the power supply to external devices such as hard drives, floppy drives, displays, mouse, and keyboard.
It is important that a quality power supply be used with the PC–600 that has sufficient current capacity, line and load regulation, hold up time, current limiting, and minimum ripple.
The power supply for the PC–600 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 PC–600 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 PC–600. If the power supply does not drain below 0.7V, the CMOS components on the PC–600 will act like diodes and forward bias, potentially damaging the PC–600 circuitry.
The proper selection of a quality power supply ensures reliability and proper functioning of the PC–600.

Chapter 3: Setup programs

This chapter discusses running the Setup configuration program on the PC–600 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 0xD8000-0xDFFFF 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 USER Setup jumper from the “S” position at W12[1–2], you may force the setup to temporarily revert to the defaults shown in the following menus, which 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 PC–600 PhoenixBIOS Setup Utility Main menu. Select the submenu by using the up/down arrows, then press <ENTER> (when using a monitor connected to the PC–600). 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 PC–600

Once you have written, tested and debugged your application, you can then save it to a hard drive or CompactFlash device. When you reboot the PC–600, 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 PC–600 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 or a hard disk 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.
49
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.
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.
st
2. Change Setup option “Boot Order” to “Boot 1
: Drive A:”.
3. Change Setup to enable the floppy.
4. Boot from floppy.
5. Change AUTOEXEC.BAT on C:.
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.

Function and use of serial ports

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 video jumper W12[5–6] must be removed. See the Console devices chapter for more information.
Mating receptacle
Use a VTC–20F or VTC–20M cable to connect the COM ports to external serial equipment. The P2 and P3 connectors are DB–9 female (VTC–20F)
or DB–9 male (VTC–20M) connectors which plug directly into a 9–pin PC serial cable.
Note When interfacing the PC–600 to your desktop PC, you must use a null
modem adapter.

P3

COM Ports as RS–232 I/O

COM1, COM2, COM3 and COM4 are 8-wire RS–232 interfaces. You can connect four serial devices. Note that COM3 and COM4 share IRQ9. You must access the COM ports to determine which generated the interrupt.
In the default configuration, the Video jumper W12[5–6] is installed. This jumper automatically disables the Serial Video option in the Advance menu in Setup, and both COM ports are available for serial I/O devices. In some instances, such as running a program on the PC–600 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.

COM3 and COM4 as RS–422 and RS–485 networks

COM3 and COM4 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.
RS–422 is a point-to-point configuration, RS–485 is a multi-node configuration that allows up to 32 nodes on a network. COM3 and COM4 can be configured as either RS–232, RS–422, or RS–485. Refer to Tables 5–1 and 5–3.
57

RS–422

–
Ω
RS–422 is typically 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 PC–600 optionally terminates with a 100 ohm resistor. Refer to Table 5–3. Figure 5–3 shows a typical RS–422 four wire interface circuit.

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 PC– 600 optionally terminates with a 100 ohm resistor. Refer to Table 5–3. Figures 5–4 and 5–5 show typical RS–485 networks.

Chapter 8: CompactFlash, SDRAM, and
battery backup

Description

The PC–600 is shipped with a 512 KB SMT flash which is soldered directly onto the PCB board. This flash contains the BIOS.

CompactFlash

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 PC–600 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.
The CompactFlash can be configured for 3V or 5V operation using jumper W13. Table 8–1 shows the jumper settings.
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 PC–600 to boot from the CompactFlash.
CAUTION
You must use an external drive such as a hard drive, floppy, or CD to sys the CompactFlash. The following instructions are shown for DOS.
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 Setup so the PC–600 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 PC–600.

Chapter 9: External drives

Description

The PC–600 is compatible with any standard IDE hard drive that has a 16-bit IDE interface. The BIOS extension ROM for the hard drive is supplied on the card so that no additional software is needed. The floppy drives use DMA channel 2.
UltraDMA modes are not supported directly by the PC–600. These modes require an 80-pin connector, and there is no adapter available for the 44­pin, 2mm IDE connector used on the PC–600.

Floppy disk controller

The PC–600 can interface directly to one or two 3.5 in. or 5.25 in. floppy drives via the connector at J12.
Note See Appendix A - Connectors for mating information. If you wish to add a
second floppy drive to your system, you must use a floppy drive cable which has two connectors and swaps the select lines.

Power requirements

The PC–600 requires +5V for operation. You must also supply power to the floppy drive(s) through an external source. Refer to your floppy drive manual for specific instructions.

Installing a floppy disk drive

1. Disconnect power to the PC–600.
2. Insert one end of your cable into the rear of the floppy drive. Make sure pin 1 on the cable is connected to pin 1 on the drive.
3. Insert the other end of the cable into J12 on the PC–600.
4. Connect power to the floppy drive.
5. Enter Setup to set up the BIOS. 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.
71

Hard disk controller

The PC–600 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 J17 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 a 44-pin connectors at J17. For those IDE devices that use a 40-pin interface, use the Octagon Systems IDE cable, #4080 or #6246.
UltraDMA modes are not supported directly by the PC–600. These modes require an 80-pin connector, and there is no adapter available for the 44­pin, 2mm IDE connector used on the PC–600.
IDE combinations:
2 hard drives
1 hard drive and 1 CD-ROM drive
CompactFlash and either of the above combinations

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 PC–600 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 PC–600.
2. Insert one end of the Octagon hard drive adapter cable into the rear of the hard drive. Make sure pin 1 on the cable is connected to pin 1 on the drive.
3. Insert the other end of the IDE cable into J17 on the PC–600. Make sure pin 1 on the cable is connected to pin 1 on the PC–600.
4. 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
72
Setup programs chapter for more information on the BIOS Setup program.
5. If you want to boot the system from the hard drive, you need to format the drive accordingly.

Chapter 10: Bit-programmable digital I/O

Description

The bit-programmable digital I/O lines can be used to sense switch closures, turn on lamps and LEDs, and interface with other devices that have TTL input or output such as printers and scales. The digital I/O lines drive the Octagon MPB series opto-isolation module racks directly, controlling AC and DC loads to 240V at 3A. Figure 10–1 shows typical I/O configurations. The digital I/O ports have the following specifications:
Each I/O chip has 24 I/O lines, grouped into 3 ports of 8 bits Each bit is programmable as either 5V input or 5V output Read back state of each pin Easy-to-program Each line can sink and source 15 mA

Interfacing to switches and other devices

The STB–26 terminal board provides a convenient way of interfacing switches or other digital I/O devices to the digital I/O port. I/O lines at the digital I/O connector can be connected to an STB–26 with a CMA–26 cable. Parallel I/O devices are then connected to the screw terminals on the STB–26. The illustration on page board connected to the digital I/O. Refer to the STB–26 product sheet for more information.

Opto-module rack interface

You can interface digital I/O lines to an 8-, 16-, or 24-position opto-module rack. One end of the CMA-26 cable plugs into the I/O connector and the other plugs into an MPB–8, MPB–16, or an MPB–24 opto rack. Refer to the MPB opto racks data sheet for more information.
You can also use a CMA–26 cable to connect the I/O port to an STB–26 terminal board and then to the opto rack. The STB–26 has two 26-pin connectors, one of which would connect to the I/O port, the other would connect to the opto rack. Refer to the illustration on page configuration, run a separate power line to +5V and ground on the opto­rack.

Organization of banks

Each I/O digital bank has a total of 24 I/O lines connected to a 26-pin header. 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.

124h* A Base address 184h** B Base address + 1 324h** C Base address + 2 384h** Control Register Base address + 3 * = default ** = selected in Setup

Base I/O address

The default base I/O address for digital I/O1 is 120h and is 124h for digital I/O2.
Digital I/O1 always uses [base through base +3], and digital I/O2 uses [base + 4 through base + 7]. Ports A, B, C and the control register are addressable, with reference to the base address. These addresses can be changed through Setup to one of four addresses.

Pulling the I/O lines high or low

Jumper blocks W2 and W4 pull the I/O lines at ports A, B, and C high or low. This allows a known state upon power-up. The default configuration pulls all of the I/O lines high. Note that 10K ohm resistor networks are used to configure the I/O lines as high or low.

Configuring and programming the digital I/O
ports
The digital I/O chip has three ports with eight parallel I/O lines (bits) per port. This chip can use one of four base I/O addresses. 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 of the digital I/O. When a line is configured as an output, it can sink a maximum of 15 mA at 0.4V or can source 15 mA at 2.4V. On power-up and software or hardware reset, all digital I/O lines at J6 and J13 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/O1 always refers to the starting
address selected in Setup (120h default). For I/O2, “base” is four greater than I/O1.
1. Write a "2" to the control register (base address + 3). This places the I/O chip in “direction” mode:
(default 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.
80

Table 10–6 Digital I/O port byte

Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Port I/O 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.
81

Digital 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)

Digital 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 'Port A data'
OUT 121h, FF 'Port B data'
OUT 122h, 0 'Port C data'
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)

Chapter 11: CRTs and flat panels

The video system on the PC–600 is implemented with the CS5530A companion chip. It supports CRTs and TFT flat panel displays. Displays from CGA through XVGA are supported. Since the video circuitry operates on the PCI bus at the full PCI bus speed, programs like Windows execute very rapidly. The PC–600 supports 3V and 5V flat panel displays.
Standard VGA monitors with analog inputs are connected using a VGA–12 cable (p/n 4865) connected to J18. Flat panel displays are connected using a 40-pin 2mm connector at J14. There is an additional connector at J16 to support a back-light for flat panels.
Note EL panels, and quarter VGA panels are not supported.

Video features

Below is a list of standard video features installed on the PC–600:
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 and 5V flat panel support
— Flat panel power sequencing
86

Connecting a monitor

To use a monitor or a flat panel, the Video jumper (W12[5–6]) must be installed. This is the default configuration. The 16–pin connector at J18 supports an analog VGA/SVGA/XVGA CRT color or monochrome monitor. Refer to figure 11–1 for a diagram of connecting a CRT, and table 11–1 for the pin-out for J18.
The PC–600 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
To connect a monitor to the PC–600 you will need the following equipment (or equivalent):
PC–600 CPU card VGA-12 video cable, p/n 4865

Chapter 12: Ethernet

Description

The PC–600 provides two 10/100BaseT Ethernet ports and supports the IEEE 802.3 Ethernet standard. The PC–600 uses the Intel 82551ER Ethernet chips. These chips are fully Plug-N-Play compatible. The Ethernet controller IC chips provide the following:
8K x 16 SRAM buffer Integrated 10/100 BaseT transceiver interface Two LEDs for link and traffic status integrated into connector
The PC–600 Ethernet uses twisted–pair wiring cable, which is built in a star configuration. The interface terminates at the standard, 8-position, RJ–45 latching jack.

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. Peripherals can be plugged in and unplugged while power is applied to the system. The PC–600 contains two 1.1 compliant USB ports.
The two USB ports are accessed via a 10-pin, 0.1” pitch connector at J3. Octagon provides a cable that routes the J3 signals to standard USB connectors (Octagon p/n 6288). This cable consists of two five-pin connectors that mate with the J3 connector on one end, and two USB connectors at the other end. Ensure that the arrow on the five-pin connectors is matched to the pin 1 end of J3. Any USB device can then plug into either USB interface on the USB adapter cable, or into a multi­port hub that then plugs into the USB adapter cable.
An operating system capable of utilizing the USB ports and USB devices is required for USB operation.
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 (J3). You can hot swap a device through the USB Adapter cable connected to J3, or through another USB connector wired to the 10-pin header, but you cannot hot swap at the 10-pin header itself.

Chapter 14: Audio

Description

The audio feature provides microphone in, stereo line in and line out, PC beep speaker, and stereo speaker. Audio is accessed via a 20-pin, 0.1” pitch connector at J20. Octagon provides a cable that routes these functions out to industry-standard connectors (Octagon p/n 6279). Figure 14–1 shows the audio cable.

Chapter 15: PC/104 and PC/104 Plus
expansion

Description

The PC/104 and PC/104 Plus connectors allow 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. The PC/104 Plus expansion bus supports mastering devices.
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.
The situation is even more critical for the PC/104 Plus connector since the bus speed is four times faster. The PC/104 Plus connector and the PC/104 Plus module represent one load each. Adding more than one PC/104 Plus module (two loads) should trigger the same testing as discussed in the previous paragraph.
