This manual describes the hardware installation steps for BS-PCC-3428 PC/104 industrial computer motherboard.
The PCC‑3428 is a compact 90 mm × 96 mm PC/104‑form‑factor industrial computer motherboard. It integrates an STPC Atlas CPU (enhanced 486 DX/DX2) with optional frequencies up to 133 MHz, up to 64 MBytes of SDRAM, a 2‑D graphics controller, Ethernet, DOC flash storage, USB, IDE, and a 16‑bit GPIO array. The board is designed for embedded applications such as medical devices, instrumentation, and network terminals.
This installation guide walks the user through connector identification, jumper settings, wiring of CRT/LCD displays, keyboard/mouse, serial ports, IDE devices, and power input. It also covers BIOS configuration, driver installation, and troubleshooting tips, with appendices that list system resources and provide GPIO programming examples. This manual is written in Chinese.
