Card Status LEDs
The card LEDs report the lock status of the device. See the table below for an explanation of each
function.
LED NAME DESCRIPTION
LOCK LED Flashes green when not locked to input signal. When locked illuminates steady
green. When S3 or S4 not at 0, indicates state of parameter.
NTSC LED On when locked to NTSC input, off otherwise

Reference Configuration and Termination
The DAC-104 can use either a reference connected to the openGear™ frame, or a reference connected
directly to BNC 2 to align the SCH phase of the output video. To use BNC 2 as the reference, set S12 to BNC-
2. To use the openGear™ frame’s reference, set S12 to FRAME and then select which of the two frame
references to be used using S11. It is important to note that the DAC-104 does not operate as a frame
synchronizer. The output video timing will always match the SDI input timing.
