This manual provides detailed instructions on how to install and use the CV-131A / CV131B SUN Signal Converter Cable
The CV-131A and CV-131B are ATEN PS/2‑to‑SUN interface converters that translate PS/2 keyboard and mouse signals to Sun-compatible signals, enabling Sun servers to be integrated into IBM‑compatible KVM installations. The CV-131A works with SPHD‑15 KVM switches, while the CV-131B is designed for standard PS/2‑VGA switches.
This manual covers safety notices, system requirements, step‑by‑step installation, hotkey operation for language selection and USB reset, Sun keyboard emulation, troubleshooting tips, and full technical specifications of the converters.
