Page 3: Important Safe-Handling Information
Always store this product in ESD-protective packaging when not in use. Safe Handling Precautions The ETX-945 contains numerous I/O connectors that connect to sensitive electronic components. This creates many opportunities for accidental damage during handling, installation and connection to other equipment. The list here describes common causes of failure found on boards returned to Diamond Systems for repair. -
Page 4: Introduction
10/100Mbps Ethernet, SATA and IDE storage devices, USB 2.0, audio, serial, parallel, and PS/2 ports. Additionally, the ETX-945 provides a high degree of system expansion flexibility via the presence of both 32-bit PCI and 16-bit ISA expansion buses on its ETX 3.0 compliant baseboard interface connectors. -

2.3 Bus and Interface Connector Summary The ETX-945 has six interface connectors, as listed in the tables below. These connectors are defined in accordance with the ETX 3.0 Computer-on-Module (COM) Specification. Signal functions relating to each of the ETX-945’s interface connectors are discussed in greater detail in Section 4 of this document. -
Page 10: Getting Started
3. GETTING STARTED This section of the ETX-945 User Manual covers basic hardware setup, power connection, system boot-up, and initial software configuration. First-time ETX-945 users normally receive the product as part of one of Diamond’s Development Kits, which provide everything needed to ensure rapid application development. -

If the SO-DIMM memory module is not already installed, carefully insert it into the socket provided on the top- side of the ETX-945 module. Refer to the specifications in the introduction of this manual for memory capacity and speed requirements. -
Page 12: Booting The System
Using the four long screws provided with the heat-spreader (or heatsink), secure the heat-spreader (or heatsink) to the corresponding standoffs located in the four corners of the top of the ETX-945 module. If the ETX module is to being installed in an enclosure, align the heat-spreader’s (or heatsink’s) corner mounting holes with corresponding hole-pattern on the enclosure before inserting and tightening the four mounting screws. -
