1.7 Safety Precautions Warning! Always completely disconnect the power cord from your chassis whenever you work with the hardware. Do not make connections while the power is on. Sensitive electronic components can be damaged by sudden power surges. Only experienced electronics personnel should open the PC chassis. Caution! Always ground yourself to remove any static charge before touching the motherboard. Modern electronic devices are very sensitive to static electric charges.
Caution! Danger of explosion if battery in correctly replaced. The battery need not to be charged. Replace only with Advantech-specified batteries. 1.8 Jumper Settings This section provides instructions on how to configure your motherboard by setting the jumpers. It also includes the motherboards's default settings and your options for each jumper. 1.8.1 How to set jumpers You can configure your motherboard to match the needs of your application by setting the jumpers.
Table 1.3: CMOS (J1) Clear CMOS data 2-3 closed * default setting 1.8.3 Watchdog timer output (J2) The AIMB-742 contains a watchdog timer that will reset the CPU or send a signal to IRQ11 in the event the CPU stops processing. This feature means the AIMB-742 will recover from a software failure or an EMI problem. The J2 jumper settings control the outcome of what the computer will do in the event the watchdog timer is tripped. Table 1.
512 and 1024 MB. The sockets can be filled in any combination with DIMMs of any size, giving a total memory size between 128 MB and 4 GB. Note: System resources such as PCI and AGP cards require physical memory address locations that reduce available memory addresses above 3GB. This may result in less than 4GB of memory being available to the operating system and applications. Limitation: The system configuration does not show the memory bank when booting. 1.9.
density (128 Mb, 256Mb or 512Mb and same in CSA latency. Any other memory configuration will result in single channel memory operation. 1.10 Memory Installation Procedures To install DIMMs, first make sure the two handles of the DIMM socket are in the "open" position. i.e. The handles lean outward. Slowly slide the DIMM module along the plastic guides on both ends of the socket. Then press the DIMM module right down into the socket, until you hear a click.
CHAPTER 2 Connecting Peripherals 15 Chapter 2
Chapter 2 Connecting Peripherals 2.1 Introduction You can access most of the connectors from the top of the board while it is installed in the chassis. If you have a number of cards installed or have a packed chassis, you may need to partially remove the card to make all the connections. 2.2 Primary (CN1) and Secondary (CN2) IDE Connectors CN1 CN2 You can attach up to four IDE (Integrated Drive Electronics) drives to the AIMB-742’s built-in controller.

While setting CF as master, the other IDE device connected to secondary IDE can work as a slave device only and vice versa. 2.3 Floppy Drive Connector (CN3) CN3 You can attach up to two floppy disk drives to the AIMB-742's onboard controller. You can use 3.5" (720 KB, 1.44 MB) drives. The motherboard comes with a 34-pin daisy-chain drive connector cable. On one end of the cable is a 34-pin flat-cable connector.
2.5 USB Ports (CN6/CN63) CN6/CN63 The AIMB-742 provides up to eight ports of USB (Universal Serial Bus) interface, which gives complete Plug & Play and hot swapping for up to 127 external devices.The USB interface complies with USB Specification Rev. 2.0 support transmission rate up to 480 Mbps and is fuse-protected. The USB interface can be disabled in the system BIOS setup. 2.6 VGA Connector (CN7) CN7 The AIMB-742 includes a VGA interface that can drive conventional CRT displays.
2.7 Serial Ports (COM1 : CN9; COM2 : CN10 ) CN9 CN10 The AIMB-742 offers two serial ports, CN9 as COM1 and CN10 as COM2. These ports can connect to serial devices, such as a mouse or a printer, or to a communications network. The IRQ and address ranges for both ports are fixed. However, if you want to disable the port or change these parameters later, you can do this in the system BIOS setup. Different devices implement the RS-232 standard in different ways.
2.9 External Keyboard Connector (CN12) CN12 In addition to the PS/2 mouse/keyboard connector on the AIMB-742's rear plate, there is also an extra onboard external keyboard connector. This gives system integrators greater flexibility in designing their systems. 2.10 CPU Fan Connector (CN14) CN14 If fan is used, this connector supports cooling fans of 500mA (6W) or less. 2.11 System FAN connector (CN15 and CN37) If fan is used, this connector supports cooling fans of 500mA (6W) or less.
2.12 Front Panel Connectors (CN16, 17, 18, 19, 21&29) There are several external switches to monitor and control the AIMB-742 CN16,17,18,19,21,29 2.12.1 Power LED and Keyboard Lock (CN16) CN16 is a 5-pin connector for the power on LED. Refer to Appendix B for detailed information on the pin assignments. If a PS/2 or ATX power supply is used, the system's power LED status will be as indicated below: Table 2.
2.12.4 HDD LED (CN19) You can connect an LED to connector CN19 to indicate when the HDD is active. 1 2.12.5 ATX soft power switch (CN21) If your computer case is equipped with an ATX power supply, you should connect the power on/off button on your computer case to CN21. This connection enables you to turn your computer on and off. 2.12.6 SM Bus Connector (CN29) This connector is reserved for Advantech's SNMP-1000 HTTP/SNMP Remote System Manager.
2.14 USB and LAN ports (CN31 and CN32) CN32 CN31 The AIMB-742 provides up to eight USB (Universal Serial Bus) ports, which gives complete Plug & Play and hot swapping for up to 127 external devices.The USB interface complies with USB Specification Rev. 2.0 support transmission rate up to 480 Mbps and is fuse-protected. The USB interface can be disabled in the system BIOS setup. The AIMB-742 is equipped with one or two high-performance Ethernet interfaces, which are fully compliant with IEEE 802.
2.16 Line Out, Mic IN connector (CN55) The Line Out is to output the audio signal to external audio device, like speakers or headphones. The Mic IN is to input the audio signal via microphones. 2.17 Audio input from CD-ROM (CD IN; CN56) The CD IN is a connector for CD-ROM to input the audio signal. 2.18 Aux Line-In connector (AUX IN; CN57) The connector is for audio device with Line-in connector.

To direct the audio signal output to the rear audio ports, the 5 and 6 pins, 9 and 10 pins must be shorted by jumper to activate the rear panel audio function. 2.
The 8-pin alarm board connector is for Advantech chassis with alarm board. 2.22 Case Open Connector (CN64) The 2-pin case open connector is for chassis with case open censor. While opening the case, the buzzer on motherboard will ring. 2.23 Serial ATA interface (SA0 and SA1) In addition to the two EIDE interfaces (up to four devices), the AIMB742 features high performance serial ATA interface (up to 150MB/s) which eases cabling to hard drives with thin and long cables.
2.24 Connecting to SNMP-1000 remote manager Use the 6-pin to 8-pin cable to connect the motherboard to SNMP-1000. This cable comes with the SNMP-1000. CN21 CN18 CN19 CN29 PIN 1 (red) PIN 1 (red) CN19 SNMP-1000 CPU Card 2.25 Auxiliary 4-pin power connector (ATX1) To ensure the sufficiency of power supply for Pentium® 4 motherboard, one auxiliary 4 pin power connector is available on AIMB-742. It is strongly suggested to use ATX1 while the system is unstable.
