A Power LED — Indicates power is applied.
B Rate indicators (MDA 4V HD-SDI only) — These indicators light to indicate the detected input video rate on the HD-SDI input BNC connector. The recognized rates are 270 Mbps, 1.485 Gbps, or 2.97 Gbps.
C Unknown rate indicator (MDA 4V HD-SDI only) — When lit, this LED indicates that an input is detected on the HD-SDI input BNC connector but that the MDA did not recognize the rate.
