  • Page 2: Copyright

    Octagon Systems Corporation general policy does not recommend the use of its products in life support applications where the failure or malfunction of a component may directly threaten life or injury.

  • Page 3: Using Cmos Circuitry In Industrial Control

    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.

  • Page 4: Avoiding Damage To The Heatsink Or Cpu

    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 power is off. If you apply 5V to the input of a TTL chip with the power off, nothing will happen.

    Chapter 14: Watchdog timer and hardware reset Description The watchdog timer is a fail-safe against program crashes or processor lockups. It has programmable timeout periods of 1, 10 and 60 seconds. The watchdog timer can be enabled or disabled in Setup. INT17 software calls (a DOS TSR) or an operating system driver can be used to enable and set the timeout period, strobe the watchdog, and disable the watchdog timer from your application.

  • Page 81: Watchdog Function Definitions Using Enhanced Int 17H Handler

    Watchdog function definitions using enhanced INT 17h handler This section provides definitions for the watchdog functions using the INT17 handler, stored in the extended BIOS area that is enabled by the X switch, or the I17HNDLR.EXE utility. I17HNDLR.EXE is a TSR program. Once executed it is active, but it must be executed each time the system is rebooted.

  • Page 82: Strobe Watchdog

    Strobe watchdog Function: Subfunction: Purpose: To strobe the watchdog. Calling registers: ffffh Return registers: None Comments: This function strobes the watchdog. Once the watchdog is enabled, it has to be strobed at a period greater than the timeout period or until the watchdog is disabled.

  • Page 83: Hardware Reset

    Hardware reset The reset switch (Switch SW1) allows you to reset the system without turning off the power. This provides a more complete reset than the <CTRL><ALT><DEL> method. 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 switch, and to Appendix B, Software utilities, for information on the Reset utility.

  • Page 84: Chapter 15: Serial Eeprom

    Chapter 15: Serial EEPROM Description A 1024-word serial EEPROM is available to the user. 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.

  • Page 85: Write A Single Word To The Serial Eeprom

    Write a single word to the serial EEPROM Function: Subfunction: Purpose: To write a single word to the on–board serial EEPROM.

    Chapter 16: System switches, user switch, BIOS update, system functions, CPU speed, CPU fan and LEDs System switches Various system function options are selected with Switch 4. The “S” switch selects whether the card boots from user defined parameters (defined in the Setup Programs chapter), or the BIOS defaults. Setting this switch Off allows the user to return to factory programmed defaults.

  • Page 89: Extended Bios Switch

    Extended BIOS switch The extended BIOS switch is position 2. The extended BIOS memory region (D8000h to DFFFFh) contains the Octagon INT17 functions. When this switch is Off, this memory region is freed up for other uses. Note that if you want to use the INT17 functions, you must either leave the switch On or copy those functions elsewhere.

  • Page 97: System Locks Up On Power-Up; May Or May Not Respond To Reset Switch

    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.

    RESET.COM Purpose This support command enables the watchdog timer and allows time–out to expire, thus restarting the system. Syntax RESET Remarks The RESET command also restarts all the expansion I/O cards on the bus. This differs from a <CTRL><ALT><DEL> reboot of the system which only restarts the system but not the expansion cards.
