2. Installation Procedures
Step 1. Determine if the computer need to receive available video re olution from the di play device or from the internal memory of the DA103-217. Set the
EDID witch to INT for u ing the DA103-217 internal memory or EXT to u e the di play re olution . The witch i located on the ide of the unit and
i acce ible through a rectangular opening.
Step 2. U e the video cable provided and connect one end to the di play and the other end to the output of the DA103-217.
Step 3. Connect the long cable from the ource to the DA103-217 video input.
Step 4. Apply power to the DA103-217 u ing the adapter provided. The Power/Signal Pre ent LED i RED if there i power
and GREEN if a ignal i pre ent.
Step 5. Set the adju tment potentiometer a follow :
EQ= Minimum (full CCW) GAIN = Minimum (full CCW) SYNC ADJ = Midway (50%)
Step 6. If the image i vi ible, tart by adju ting the EQ until the image i clear. A 250 ft (76 m) cable require near maximum equalization. If there i no
image, tart by lowly increa ing the SYNC ADJ. Stop adju ting when the image i vi ible.
Step 7. While viewing the image on the di play, fine-tune the image u ing the EQ and GAIN adju tment .
Step 8. Next, fine-tune the SYNC ADJ for the be t image/ creen po ition.
Step 9. The DA103-217 i now operational.

5. About Your DA103-217
•Recover ignal after 250 ft (76 m) of ultra-thin VGA cable
•Equalization/gain adju t for image optimization
•Compact and turdy
•AGC control for ync re toration
•Internal or external EDID election
The DA103-217 i a VGA line receiver for long cable run u ing RGBHV or VGA type cable . It connect to the di play end and allow adju tment of video
equalization, gain, and ync thre hold to recover degraded analog ignal and improve video quality. The DA103-217 can compen ate for up to 250 ft (76 m) of
ultra thin VGA cable.
Cable run over 75 ft (23 m) probably need and hould have thi line receiver. In application without the DA103-217, cu tomer may complain about image
mearing, blurrine , and other di tortion . The DA103-217 eliminate mearing and other di tortion while making letter and graphic harp and legible.
It i recommended to in tall the DA103-217 at the di play end for be t re ult . It mall ize allow ea y in tallation behind a di play or in a ceiling pace while
the metal enclo ure provide trength and protection for long life and reliability.
Other feature include a ignal pre ent indicator that how when a ignal i pre ent, AGC control for ync recovery, and internal or external EDID election for
proper computer etting to match di play re olution.

7.1.1 Eq
Video equalization i provided to fine-tune the di played image on the
remote di play. Typically, for hort cable run the equalization will be
et to near minimum. Cable length up to 250 ft (76 m) will require
near maximum equalization.
7.1.2 Gain

power and a SYNC ignal.
Cau e 1: No AC power.
Solution: Verify the adapter i plugged into a working AC outlet and
that the outlet ha power.
Cau e 2: Adapter i not plugged into DA103-217.
Solution: Verify the DC power plug coming from the AC adapter i
plugged all the way into the DA103-217.
Cau e 3: The DA103-217 ha a problem.
Solution: If there i AC power to the adapter and the LED till doe not
turn on, call ALTINEX at [phone].
