  • Page 9: General Precautions

    ETX-CN700 Precautions General Precautions Your Single Board Computer is susceptible to damage by electrostatic discharges. In order to avoid damage, you should work at an anti-static bench and observe normal anti-static precautions. Wear an anti-static wrist strap connected to an earth point before opening any packaging. Where a wrist strap is not available, discharge any static charge you may have built-up by touching an earth point.

  • Page 10: Bios & Cmos Memory

    ETX-CN700 Precautions BIOS & CMOS Memory Please be aware that with personal computer products, it is possible to create configurations within the BIOS make booting impossible. Unlike most personal computer products, the ETX-CN700 stores the BIOS settings in Flash memory rather than CMOS which allows these settings to be remembered even if there is no battery present.

  • Page 11: Quick Start

    The following sections explain how to install the ETX-CN700 Single Board Computer onto your host board. As this single board computer can be installed onto a variety of host boards, the BlueChip Technology MagnumX product has been used as an example host board.

  • Page 12: Assembly

    ETX-CN700 Installation Assembly Connector locations Figure 1: Connector Locations With an ETX Single Board Computer, the main connections for Keyboard, Mouse, Video, IDE, USB etc are made via the Host Board. On the ETX CN700 there are only two direct connections, both of which are SATA connectors.
  • Page 13 ETX-CN700 Installation Figure 2: ensure mounting pillars are fitted to host board The next action is to carefully align the connectors of the ETX CN700 with those on the host board and carefully press together. Note: The Hirose connectors are offset from each other, so the ETX CN700 will only fit on one orientation. Trying to force the ETX CN700 in the wrong orientation may damage the connectors Figure 3: Align ETX CN700 connectors with the host board If the memory module is not already fitted, then carefully fit the memory module onto the memory socket.

  • Page 14: Cooling

    ETX-CN700 Installation Cooling Efficient cooling is essential for long and reliable operation of any electronic equipment. The VIA Eden/C7/Nano CPU, the VIA CN700 Northbridge and VIA VT8237 Southbridge do get hot in normal operation, and in an elevated ambient temperature will require additional cooling. Cooling requirements will vary with application, desired operating temperature, CPU load, and memory size and board orientation.
  • Page 15 ETX-CN700 Installation The Active solution has thermal pads attached to the bosses on the base of the finned heatsink which make direct contact with the surface of Northbridge, Southbridge and two voltage regulators to help dissipate heat into the heatsink. Figure 5: Heatsink bosses and thermal pads Before fitting the active solution, it is necessary to spread some thermal grease to the surface of the boss which will contact the CPU.

  • Page 16: Stack Heights And Clearances

    ETX-CN700 Installation Stack Heights and Clearances The MagnumX stack heights for the above example are shown below. Figure 7: MagnumX with Active Cooling Stack dimensions Stack heights will depend on the length of the Hirose connectors on the host board. For example, the MagnumX uses longer connectors on the base board to allow for high components on the host board, so there is a board to board gap of 10mm.

  • Page 33 ETX-CN700 Appendix 1 Connector X2 ISA Signals All required signal pull-ups are integrated into the ETX CN700 module. In some applications it may be desirable to add additional signal termination components to the baseboard. SD[0..15] These signals provide data bus bits 0 to 15 for any peripheral devices. All 8-bit devices use SD0[0..7] for data transfers.
  • Page 34 ETX-CN700 Appendix 1 IOCS16# The IOCS16# signal determines when a 16-bit to 8-bit conversion is needed for I/O bus cycles. A conversion is done any time the CPU module requests a 16-bit I/O cycle while the IOCS16# line is high. If IOCS16# is high, 16-bit CPU cycles are automatically converted on the bus into two 8-bit cycles.
