  • Page 29: Selecting The Stack Order For The Cmx34Kb

    Selecting the Stack Order for the CMX34KB There are several things to consider when selecting the order of boards in the stack. Before selecting the order, be sure to determine which bus connector on each board is the “Active” bus. Typically, if a peripheral module has both PCIe and PCI bus connectors, only the PCIe is active, and the PCI is pass-through.

    WARNING Incorrect modifications to the BIOS can cause your system to break. If you are unsure of any changes made to the BIOS there is a Load RTD Defaults option under the Exit tab in the SCU. This option restores the BIOS to the default factory settings.

  • Page 61: Operating System Specific Usage

    Operating System Specific Usage Windows® The CMX34KB is fully supported under Windows 10. While Windows 7 isn’t officially supported, it can work using a work-around <link to work-around>. Both 32-bit and 64-bit editions are supported. Drivers for onboard peripherals such as video and Ethernet are provided on the companion DVD that is shipped with the board.

  • Page 62: Non-Standard Serial Port Modes

    It is possible to change the input clock rate for the UARTs of the cpuModule to allow the serial ports to operate at higher speeds than 115,200 bps. This is accomplished by modifying the baud rate multiplier for each serial port. Non-standard baud rates are supported for all COM port modes of the CMX34KB: Table 30 Baud Rate Multiplier Registers...

  • Page 63: Advanced Digital I/O Ports (Adio™)

    TTL/CMOS compatible digital I/O (TTL signaling). These I/O lines are grouped into two ports, Port 0 and Port 1. Port 0 is bit programmable; Port 1 is byte programmable. Port 0 supports RTD’s Advanced Digital Interrupt modes. The three modes are strobe, match and event. Strobe mode generates an interrupt and latches Port 0 when the strobe input transitions from low to high.

    SATA Controller Configuration The CMX34KB has six SATA 3.0 links with transfer speeds up to 6 Gbps. Two SATA links reside on the top PCIe/104 Type 2 connector (CN1), and two SATA links reside on the bottom PCIe/104 Type 2 connector (CN2).

  • Page 68: Watchdog Timer Control

    The Advanced Watchdog Timer has a Setup Register and a Runtime Register. The Setup Register is set by the BIOS and can be adjusted by entering the BIOS Setup Utility, and going to “Advanced”, “RTD Advanced Options”, “RTD Miscellaneous Feature Control”. The Setup Register may also be read by the driver to determine if the Watchdog is enabled, and the interrupt and base address that it is using.

  • Page 69: Thermal Management

    Upon entering the Critical Trip state, the operating system will issue a command to the processor, and the CMX34KB will immediately transition to the S5 (Soft-Off) ACPI power state. To exit the Critical Trip state (and S5), the CPU temperature must be reduced to a point that the internal thermal sensors are below the Critical Trip Point.

  • Page 70: Power Management

    Power Management The CMX34KB cpuModule supports various powering mechanisms which allow the cpuModule to monitor power consumption and temperature and achieve minimal power consumption states. These unique features include thermal monitoring and thermal throttling, as well as ACPI low power modes. Various wake options are also available to resume normal system power.

  • Page 71: At Vs. Atx Power Supplies

    AT vs. ATX Power Supplies Both AT and ATX power supplies may be used with the CMX34KB cpuModule, however AT power supplies do not provide any standby power to the cpuModule.

    Trusted Platform Module The CMX34KB cpuModule includes a Trusted Platform Module (TPM) that is fully compliant to the Trusted Computing Group (TCG) TPM version 2.0 specification. TPM stands for “Trusted Platform Module”. The TPM is a controller on your cpuModule that provides tamper resistant storage using hardware-based cryptography.

  • Page 76: Features And Settings That Can Affect Boot Time

    ROMs. During POST, the BIOS executes the card's extension code. This extension code is third-party code, which is beyond RTD's control. The BIOS extension will most likely increase the boot time. Exactly how much it increases boot time will depend on the particular card and firmware version.
