INSTALLING YOUR DA1931CT 6
Step 1. Determine the settings required for Gain,
Sync On Green, Horizontal Sync Polarity
and Vertical Sync Polarity. If necessary to
change the factory defaults, open the unit
and set the switches per DIAGRAM 4 on
page 8.
Step 2. Plug the 9V power adapter into an AC
outlet and then connect the other end to
the POWER input jack on the DA1931CT.
Step 3. Verify the LED near the top of the unit is
illuminated RED indicating power is
applied.
Step 4. Connect the CAT-5/6 cable from the video
output of the CAT-5 Transmitter to the
CAT-5 Input port on the DA1931CT.
Step 5. Verify the power LED at the top of the unit
changes to GREEN, indicating a SYNC
signal has been detected.
Step 6. Connect the stereo audio output from the
DA1931CT to the audio receiving device.
Step 7. Connect the receiving monitor to the
applicable DA1931CT Video Output
connector, either RGBHV/YPbPr, S-Video
or C-Video depending on the input type to
the transmitter.
Step 8. Verify the picture quality on the receiving
monitor is equivalent to the quality as
displayed on the local monitor at the
transmitter. If the quality of the image is
poor or non-existent, it may be necessary
to adjust the Video Equalization on the
DA1931CT and/or DA1930CT. See the
OPERATION section that follows for
details.
OPERATION 7
The DA1931CT requires only one adjustment to be
made for optimal performance. Video Equalization
is required for long cable lengths and may be
adjusted to fine tune the video display.
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 DA1931CT
Receiver and DA1930CT Transmitter 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.
