  • 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 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.
  • Page 5 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.

    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.

  • Page 98: Fxchk.exe

    FXCHK.EXE Purpose This support command checks the FlashFX flash media for bad spare units. Syntax FXCHK drive Parameter drive specifies the drive letter to check. Remarks FlashFX usually keeps at least one spare unit so that if a flash device develops a bad block, the spare unit takes it's place.

  • Page 99: Fxfmt.exe

    FXFMT.EXE Purpose This support command formats a FlashFX flash disk. Syntax FXFMT <Drive> { Options } Parameter <Drive> Specifies the drive to format. This can be either a drive letter ie. C: (if the drive has already been formatted) or drive descriptor ie.

  • Page 100: Fxinfo.exe

    After reformatting, the drive can be SYSed to become bootable which requires another boot device with an installed O/S (such as a floppy). FXFMT will not affect IDE hard drives. FXFMT uses the current SETSSD information. This defines the order and the amount of space reserved for the BIOS.

  • Page 101: Fxreclm.exe

    FXRECLM.EXE Purpose This support command removes outdated versions of files and reorganizes files on the FlashFX flash media, to improve access time. Syntax FXRECLM drive count Parameter drive specifies the drive letter to reclaim. count specifies the maximum number of operations to perform. Remarks FlashFX will reclaim the drive specified, up to the maximum number of operations specified.

  • Page 110: Reset.com

    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.
  • Page 111 Remarks Defines the SSD device order used by the flash file system. If an SSD name is included on the command line, the SSD will be enabled and can therefore be detected and used by FlashFX. If more than one SSD is listed on the command line, the first SSD will be the first drive (usually C:) and the second SSD will be the second (usually D:).
