3.1 User Controls
Figure 3.1 below shows the card-edge user interface.
3.1.1 LED Indicators
The 525/625 LEDs (green) indicate the line format of the selected input video. When the digital input is
selected, the display will indicate “525” or “625”. When the analog input is displayed, the LEDs still indicate
the line format, but the display also indicates the current composite format (NTSC or PAL).
The REF LED (green) turns on to indicate a valid composite signal has been detected on the REF IN BNC.
It will remain off if no reference signal is installed. If there is a line format mismatch between the reference
input and the selected video source, the REF LED flashes, but the output format follows the reference format
and is forced to black.
The input ERR (error) LED (red) will turn on if there is an error at the selected input or if the signal cannot be
locked. Also, if a standard is forced, for example, NTSC and the input signal detected is other than a NTSC
signal, the ERR LED will indicate an error. NOTE: in some cases, when the card is set to VCR mode (see
sect. 4.2.2) and forced standard, an incorrect input format will not be detected and the ERR LED will not
illuminate.
The EDH LED (red) turns on whenever an incoming EDH flag is detected.
The B&W LED (green) turns on when the analog video input is a monochrome signal (no subcarrier).
The TEST LED (yellow) will turn on whenever the internal test pattern is activated.
The FREEZE LED (yellow) will turn on whenever the manual freeze is enabled. It will also blink when the
card executes an automatic freeze in response to a loss of input or continuous input errors.
