INSTALLING YOUR DA1957CT 6
Step 1. Determine the best location for the
DA1957CT.
Step 2. Connect the adapter to the unit and plug it
into the power outlet. The power indicator
LED on the front panel will light. This
indicates that the unit is operational.
Step 3. Connect a cable from the CAT-5
Transmitter to the Input connector on the
DA1957CT.
Step 4. Connect one to four of the DA1957CT
output channels to CAT-5 Receivers. The
receiving devices (monitors, projectors,
speakers…) should be connected to the
CAT-5 Receivers per their User Guides.
Step 5. Adjust the equalization settings for the
best image quality.
OPERATION 7
The DA1957CT will operate successfully as long as
cables are attached properly and other technical
specifications are followed. The only adjustment on
the DA1957CT is for Video Equalization and only
needs to be made at the time of installation.
The equalization knob is a single turn adjustment.
At minimum (fully CCW), the arrow points to the 7
o'clock position and at maximum (fully CW) it
points to the 5 o'clock position.
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.
TROUBLESHOOTING GUIDE 8
We have carefully tested the supplied DA1957CT
unit and have found no problems; however, we
would like to offer the following suggestions:
8.1 LED IS NOT RED
The LED should be ON and RED when power is
applied and there is no video signal present. If
the LED is ON and GREEN, the unit is receiving
power and a SYNC signal.
Cause 1: No AC power.
Solution: Verify the adapter is plugged into a
working AC outlet, and that the
outlet has power. It is best to use
only the Altinex provided power
adapter.
Cause 2: Adapter is not plugged into
DA1957CT.
Solution: Verify the DC power plug coming
from the AC adapter is plugged all
the way into the DA1957CT.
Cause 3: The DA1957CT has a problem.
Solution: If there is AC power to the adapter
and the LED still does not turn on,
the DA1957CT or the power adapter
may require service. Call ALTINEX
at [phone].
8.2 LED IS NOT GREEN
Cause 1: There is no power.
Solution: Disconnect the video input from the
DA1957CT 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 1: Verify the computer output is
operating correctly by connecting it
directly to a local monitor. If the
display is good, see Solution 2.
