8.2 LED IS NOT GREEN
Cause 1: There is no power.
Solution: Disconnect the video input from the
DA1907SX 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 a local monitor. 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 a local monitor
and verify the quality is good. If the
local image is good, see Cause 2.
Cause 2: Cable connections are incorrect.
Solution: Make sure that cables are
connected properly. Also, make sure
that the continuity and wiring are
good. If there is still no image
present, see Cause 3. If the display
is good, call ALTINEX at (714)
990-2300.
Cause 3: Signals are bad.
Solution: Make sure that the amplitude of the
input video analog signal is less than
1.5V and the SYNC input is at a TTL
level.
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 Poor signal transmission.
Solution: Check the cables for continuity and
make sure that connections are
wired properly. If the image is still
not correct, see Cause 3.
Cause 3: Cable runs too long.
Solution: Make sure that the outputs are
terminated properly and the cable
run does not exceed 15 feet for the
local monitor output and 100 feet for
the main output port.
NOTE: The DA1907SX is capable of
driving a computer video signal up to
250 feet depending on the resolution
and cable quality.
