DL-AS21C Installation Guide
The DigitaLinx DL-AS21C is a compact multi-format switcher with
support for video resolutions up to UHD (4096x2160). Featuring
one HDMI input and one VGA input with stereo audio, the DL-AS21C
automatically or manually switches either input to a single HDMI
output.
The DL-AS21C features multiple methods of control. When set to Auto,
the switcher will automatically switch to the newest source device
added to the DL-AS21C with VGA taking precedence should multiple
sources be live simultaneously. The DL-AS21C may be manually
controlled by switching via the front panel, RS232, or contact closure.
As an added benefit, the DL-AS21C features a built-in CEC controller
to power on/off the connected display by auto-selecting the source
device's status.
