Product Introduction
ADLINK CPCI-3840AH CompactPCI Processor Board
The CPCI-3840AH is associated with the cPCI-3840 CompactPCI processor-board family, designed for embedded computing in industrial and test-system chassis. The documented base family uses a 3U CompactPCI form factor and supports Intel Pentium M or Celeron M processor configurations, with Ethernet, USB, serial, and storage interfaces. Its role is to provide the computing platform for applications that use a CompactPCI backplane and compatible peripheral boards.
The exact AH configuration remains unverified. Before ordering or installing a replacement, check the board label, processor identification, memory arrangement, storage devices, and backplane connections. Do not use specifications from unrelated CPCI-3840AH distributor listings as a substitute for the original hardware documentation.

CPCI-3840AH
Application Scenarios & Field Pitfalls
Typical application scenarios
- Industrial control computing: Executes application software within a CompactPCI-based control or monitoring chassis.
- Data acquisition systems: Provides host processing for compatible acquisition and interface boards.
- Automated test equipment: Handles test sequences, data processing, and communication with installed instrumentation.
- Legacy embedded systems: Supports existing equipment designed around the cPCI-3840 processor-board architecture.
These are application categories supported by the base board’s computing architecture, not confirmation of a specific CPCI-3840AH deployment.
Field pitfalls and verification points
- Mechanical fit: Confirm the 3U board height, slot width, front-panel arrangement, and chassis retention hardware.
- Backplane compatibility: Check the CompactPCI connector assignments and the target chassis slot before insertion.
- Memory configuration: Verify the installed RAM type, capacity, and module arrangement. Do not assume that all revisions support the same memory configuration.
- Rear I/O routing: Some interfaces are routed through the rear transition module. Confirm whether the installation requires a compatible cPCI-R3840 RTM.
- Operating temperature: The documented base configuration specifies 0°C to 55°C. Do not apply a claimed extended-temperature range to the AH variant without its specific datasheet.
- Software recovery: Confirm the original operating system, BIOS configuration, boot device, and application image before replacing the board. A physically compatible CPU board may still fail to start the original control application.

Procurement and replacement note: Request a clear photograph of the complete product label and PCB identification before purchasing. The exact AH suffix is not sufficiently documented to establish a definitive processor, temperature grade, or I/O configuration. Match the board revision and installed hardware configuration before treating another cPCI-3840 variant as interchangeable.
