    Chapter 3 Upgrading Upgrading the Microprocessor The latest revision of the MTXP-945G currently supports Intel Pentium 4 processors in an LGA775 processor socket with a 1066, 800, or 533 MHz system bus. Use Only ATX12V compliant power supplies. A good CPU cooling FAN must be used and use a plastic cooler back plate when installing the fan cooler assembly on to the CPU.
  • Page 50 Chapter 3: Upgrading MTXP-945G Technical Reference The MTXP-945G supports two types of memory organization: Dual channel (Interleaved) mode. This mode offers the highest throughput for real world applications. Dual channel mode is enabled when the installed memory capacities of both DIMM channels are equal. Technology and device width can vary from one channel to the other but the installed memory capacity for each channel must be equal.

  • Page 51: Appendix A Technical Specifications

    The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS) translation modes. The drive reports the transfer rate and translation mode to the BIOS. The MTXP-945G supports Laser Servo (LS-120) diskette technology through the Parallel ATA IDE interface. The BIOS supports booting from an LS-120 drive.

  • Page 52: Industrial Devices

    Serial ATA Interfaces The MTXP-945G features four independent Serial ATA ports with a theoretical maximum transfer rate of 300 MB/s per port. One device can be installed on each port for a maximum of four Serial ATA devices. A point-to-point interface is used for host to device connections, unlike Parallel IDE, which supports a master/slave configuration and two devices per channel.

  • Page 74: Serial Ports

    Appendix C: Industrial Devices MTXP-945G Technical Reference Serial Ports The MTXP-945G can be configured with up to six fixed RS-232 serial ports (COM1 RS-422/485 optional). COM1 and COM2 are standard, the others are optional. TIA/EIA-232 RS is the abbreviation for recommended standard. Usually, it is based on or is identical to other standards, e.g., EIA/TIA-232-F.
  • Page 75 MTXP-945G Technical Reference Appendix C: Industrial Devices The figure below shows the electrical schematic diagram of a single-ended transmission system. Advantages of Single-Ended Transmission The advantages of single-ended transmission are simplicity and low cost of implementation. A single-ended system requires only one line per signal. It is therefore ideal for cabling, and connector costs are more important than the data transfer rate, e.g.
  • Page 76 Appendix C: Industrial Devices MTXP-945G Technical Reference RS-422 is Differential and may be either Point-to-Point or Multi-Drop Connected Differential, Point-to-Point Differential, Multi-Drop Differential Transmission For balanced or differential transmission, a pair of signal lines is necessary for each channel. On one line, a true signal is transmitted, while on the second one, the inverted signal is transmitted.
  • Page 77 MTXP-945G Technical Reference Appendix C: Industrial Devices TIA/EIA-485 Historically, TIA/EIA-422 was on the market before TIA/EIA-485. Due to the lack of bi-directional capabilities, a new standard adding this feature was created: TIA/EIA-485. The standard (TIA/EIA-485-A or ISO/IEC 8284) defines the electrical characteristics of the interconnection, including driver, line, and receiver. It allows data rates in the range of 35 Mbps and above and line lengths of up to 1200 m.
  • Page 78 Appendix C: Industrial Devices MTXP-945G Technical Reference Ground Connections All 422- and 485-compliant system configurations shown up to this point do not have incorporated signal-return paths to ground. Obviously, having a solid ground connection so that both receivers and drivers can talk error free is imperative.
