    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 5266 that has sufficient current capacity, line and load regulation, hold up time, current limiting, and minimum ripple. The power supply for the 5266 must meet the startup risetime requirements specified in the ATX Power Design Guide, version 1.1, section 3.3.5.

  • Page 30: 5266 Power Supply Requirements

    5266 power supply requirements The 5266 is designed to operate from a single +5 VDC supply, connected at J11 or through the ISA connector. The J11 connector is a 2-pin screw terminal connector, and accepts 22 AWG to 14 AWG wires. The typical current requirement for the 5266 is listed in the Technical Data appendix.

  • Page 31: Installing An Operating System

    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 5266. If the power supply does not drain below 0.7V, the CMOS components on the 5266 will act like diodes and forward bias, potentially damaging the 5266 circuitry.

  • Page 45: Chapter 4: Serial Ports

    Chapter 4: Serial ports Description The 5266 has two serial ports, COM1 and COM2. COM1 is a dedicated 8-wire RS– 232C. COM2 can be 8-wire RS–232C, or 4-wire RS–422 or RS–485. COM1 and COM2 are accessed at the 20-pin connector at J4.

  • Page 46: Serial Port Configurations

    The COM port interrupts can be routed so that different interrupts are used. See page 93. If COM2 is used for RS–422 or RS–485, and the 5266 is at the end of the network, the ports will have to be terminated. Switch 2, positions 3 and 4, terminate the network.

  • Page 47: Vtc-20F Cable And Null Modem Adapter

    Position 3 On with termination Position 4 On * Default. These switches terminate the network. If the 5266 is at an end of an RS-422/485 network, set these switches to On. For RS-232 on COM2 these switches must remain Off.

  • Page 48: Function And Use Of Serial Ports

    (switch 500 position 2) must be set to Off to redirect video to a serial console. See the Console devices chapter for more information. Note When interfacing the 5266 to your desktop PC, you must use a null modem adapter. COM1 and COM2 as RS–232 I/O COM1 is a dedicated 8-wire RS–232 interface.

The I/O address for LPT1 is 278h, with interrupt IRQ7. BIOS Setup configuration for LPT1 The digital I/O connector J7 is configured in the BIOS Setup Custom Configuration menu as either a digital I/O port (default) or as an LPT parallel port.

  • Page 73: Creating A Printer Cable

    Creating a printer cable The LPT port requires a custom cable to route the signals from J7 to a printer. Do not use a standard 26-pin to DB-25 cable, as that would route +5V to pin 2, and would route the rest of the signals to incorrect pins. To build an LPT cable, use a DB-25 connector, a 26-lead ribbon cable, and a 26-pin Amp 746288-6 connector.

    500 MHz. ISA bus and onboard interrupt routing The 5266 provides for flexible routing of interrupts that originate from the ISA bus and onboard source. The interrupt routing provides flexibility to the interrupt structure, allowing the lower-ordered ISA interrupts to be connected to the unused higher-ordered interrupts.

    If using a flat panel display, check the following: 1. Cable and connections going from the 5266 to the flat panel display. 2. Power cable going to the flat panel display. 3. Power module for the flat panel. Make sure that the power module has enough current capacity to power both the 5266 and the flat panel.
