Power Input

NOTE: The LOCK LED indicates valid input video by color: green for SD, red for all other

rates, off is no input.

Installation

Typically, 12GDA installation consists of the following:

1. Connect video equipment to the BNCs.

2. Apply power to the converter (AJA power supply included).

3. The LOCK LED will light to indicate detection of the following SMPTE SDI

rates:

• Red: 12G 11.868 Gbps, 11.880 ST 2082

• Red: 6G 5.934 Gbps, 5.940 Gbps ST 2081

• Red: 3G 2.967 Gbps, 2.970 Gbps ST 424

• Red: HD 1.483 Gbps, 1.485 Gbps ST 292

• Green: SD 270 Mbps ST 259-C
