INSTALLING YOUR DA1930CT 6
Step 1. Plug the 9V power adapter into an AC
outlet and then connect the other end to
the POWER input jack on the DA1930CT.
Step 2. Verify the LED near the top of the unit is
illuminated RED indicating power is
applied.
Step 3. Connect the video output from the local
computer to one of the video inputs, either
RGBHV/YPbPr or S-Video or Composite
Video.
Step 4. Verify the power LED at the top of the unit
changes to GREEN, indicating a SYNC
signal has been detected.
Step 5. Connect the stereo audio output from the
local computer to the AUDIO input on the
DA1930CT.
Step 6. Connect the local monitor to the LOCAL
OUTPUT video connector labeled
RGBHV/YPbPr on the DA1930CT.
Step 7. If using external speakers on the local
device, connect the local audio speaker
inputs to the LOCAL OUTPUT labeled
AUDIO on the DA1930CT.
Step 8. Connect a CAT-5 cable to one of the
4TP OUTPUT connectors on the
DA1930CT. The other end of the cable
should be connected to a DA1931CT
Receiver, and the receiver should be
connected to a monitor device and audio
device.
Step 9. Verify the picture quality on the receiving
monitor is equivalent to the quality as
displayed on the local monitor. If the
quality of the image is poor or
non-existent, it may be necessary to
adjust the Video Equalization on the
DA1930CT and/or DA1931CT. See the
OPERATION section that follows for
details.
OPERATION 7
The DA1930CT requires only two adjustments to
be made for optimal performance. The first is Video
Equalization for long cable lengths. The second is
Audio Gain for volume control of the main (CAT-5)
output,
7.1 VIDEO EQUALIZATION
Video Equalization is provided to fine tune the
displayed image on the remote display.
Typically, for short cable runs the equalization
will be set to near minimum. Cable lengths up to
400 feet will require near maximum equalization.
The equalization adjustments on the DA1930CT
and DA1931CT work together to provide
equalization for maximum cable lengths. For
example, for cable runs less than 50 feet, both
equalization settings may be set to
approximately minimum, since on the short
distances no equalization is required. Where as
cable runs of 400 feet will see equalization
settings at about the three-quarter position.
7.2 AUDIO GAIN
Normally, the AUDIO GAIN control on the
DA1930CT will be set to maximum. When set to
maximum, the transmitted volume will be
equivalent to the volume from the audio source.
If necessary, the transmitted volume may be
reduced as required by the user.
