Page 8: The Ai-207 Board Overview
18-bit resolution and 12 software-selectable input gain ranges. Board Overview DNA-AI-207, DNR-AI-207, and DNF-AI-207 boards are compatible with the UEI Cube, RACKtangle, and FLATRACK chassis respectively. These board versions are electronically identical and differ only in mounting hardware. The DNA version is designed to stack in a Cube chassis. -
