Cause 3: The DA1921SX has a problem.
Solution: If there is AC power to the adapter
and the LED still does not turn on,
the DA1921SX or the power adapter
may require service. Call ALTINEX
at (714) 990-2300.
8.2 LED IS NOT GREEN
Cause 1: There is no power.
Solution: Disconnect the video input from the
DA1921SX and verify the LED is ON
and RED indicating power is
present. Reconnect the computer's
video output. If the LED is still not
GREEN see Cause 2.
Cause 2: There is no Sync signal.
Solution: Verify the computer output is
operating correctly by connecting it
directly to the local monitor,
bypassing the transmitter and
receiver. If the display is good, call
ALTINEX at (714) 990-2300.
8.3 NO REMOTE IMAGE
Cause 1: The source has a problem.
Solution: Check the image on the local
monitor and verify the quality is
good. If the local image is good, see
Cause 2.
Cause 2: Video equalization required.
Solution: Adjust the VIDEO EQUALIZATION
on the DA1921SX. Long cable runs
may require adjustment on both the
DA1921SX and the DA1920SX.
In general, cable runs less then 50
feet require little or no video
equalization and should be set to
minimum. Longer cable runs will
require equalization on both the
transmitter and receiver.
8.4 REMOTE IMAGE QUALITY IS POOR
Cause 1: The source has a problem.
Solution: Check the image on the local
monitor and verify the quality is
good. If the local image is good, see
Cause 2.
Cause 2: Video equalization required.
Solution: Adjust the VIDEO EQUALIZATION
on the DA1921SX. Long cable runs
may require adjustment on both the
DA1921SX and the DA1920SX. If
the image is still not correct, call
ALTINEX at (714) 990-2300.
