AC217A - Intelligent Video Scaler

INSTALLATION STEPS:
1. Connect the provided AC power cord into the connector marked Power on the rear of AC217A and plug
the other end into an AC outlet. This is an auto-sensing universal input power supply and is compatible with
worldwide standards.
2. Connect a video source to either the COMPOSITE, S-VIDEO or COMPONENT input on the rear panel using
one of the input cables supplied.
3. Connect a computer monitor, projector or display to the VGA compatible connector on the rear panel.
AVAILABLE OUTPUTS:
There are three outputs configurations available on the output VGA connector: RGBHV, RGBS and Y-CB-CR. The
rear panel switch next to the output connector selects one of the three output types. The individual signals on the
HD-15 connector are defined on page 7. Rear connector pin-outs for the output configuration are selected by this
switch.
REMOTE CONTROL:
AC217A provides for a hard-wired RS-232 remote control connection using a 3-pin Phoenix-type connector on the
rear panel. The baud rate is 9600 baud, no parity, 1 start bit, 1 stop bit. The pin out is as follows:
1 - Ground 2 - Receive Data 3 - Transmit Data

Thank you for purchasing AC217A, the Intelligent Video Scaler designed especially for use with HDTV and DTV
displays. With AC217A, you now have the ability to enjoy high-resolution, film-like images from any standard video
source, including broadcast or cable TV ,video tape, DVD and laser disc. AC217A offers a unique automatic motion
compensation feature that will adapt to the specific type of input source image.
When processing NTSC sources, AC217A's motion compensation feature automatically selects one of three different
motion compensation techniques: adaptive frame (inverse 3:2 pulldown) for original film material, vertical temporal
and static mesh. (When processing PAL sources, inverse 3:2 pulldown is not applicable.) Because each technique is
set specifically for the type of input image, the result is the clearest, crispest picture quality possible, making AC217A
ideal for Home Theater and Professional A/V applications. Packed with other great features such as three different
aspect ratio conversions, AC217A is one incredibly versatile scaler. Additional features include Composite, S-Video
and Y-CB-CRcomponent inputs and RGB or Y-CB-CRcomponent outputs, plus an RS-232 remote. An internal power
supply and simple, intuitive user-interface round out this sleek, compact unit.
INTRODUCTION
INSTALLATION

AC217A - Intelligent Video Scaler

AC217A is designed to operate properly with any projector or display while requiring minimal set-up and adjustments.
SELECTING AN INPUT:
There are three buttons on the front panel for directly selecting one of the three inputs. The LED that is lit indicates
the active selection. The three input options are:
Video (composite)
S-Video (Y/C)
Y-CB-CR (component)
SELECTING AN OUTPUT FORMAT:
AC217A provides the five output formats listed below. Pressing the output format button on the front panel will cycle
through the choices. The LED that is on indicates the current output format.
480p
720p
1080p
1280 x 1024
1366 x 768
SELECTING AN ASPECT RATIO:
AC217A's unique preset aspect ratio conversion offers the user three choices for changing the input aspect ratio to
the desired output image aspect ratio. It is important to select the appropriate conversion setting in order for the output
image to appear geometrically correct.
16:9 to 16:9
This conversion scales a 16:9 crop of the input video raster and maps it to the output as a full screen image. It is intended
for displaying original letterbox images as a full screen image on 16:9 displays.
Input:
Letterbox in
4:3 frame
Output:
Full 16:9
frame
4:3 to Full Screen
This conversion takes the entire input video raster and maps it to the entire output raster. If the output display aspect
ratio is 4:3, the image will appear with the same geometry as shown on the input. If the output display aspect ratio is
16:9, the image will appear to be "stretched" in the horizontal direction. This is useful if the input video source was
an anamorphically compressed DVD, as it will now appear to be geometrically correct on the 16:9 display. Refer to
diagrams on top of page 5.
Note: This mode is not available with PAL input to 480p output.

OPERATION
AC217A - Intelligent Video Scaler

4:3 to 4:3 in 16:9 Screen
This conversion is intended to display a standard, full screen 4:3 input on a 16:9 display with the correct geometry.
AC217A will place the 4:3 image centered in the 16:9 display with black on either side of the active image.
Note: This mode is not available with PAL input to 480p output.
SPECIAL KEY FUNCTIONS:
There are several functions that can be activated by pressing a combination of keys simultaneously:
Key Panel Lockout: Press the VIDEO and S-VIDEO buttons at the same time to lock out the key panel.
Key Panel Unlock: Press the S-VIDEO and COMPONENT buttons at the same time to unlock the key panel and allow
normal operation.
System Reset: Press the COMPONENT and the OUTPUT FORMAT buttons at the same time to reset the unit and
return all settings to their factory defaults.
MOTION COMPENSATION:
The automatic motion compensation feature will analyze the input source and choose the appropriate compensation.
AC217A will automatically select between inverse 3:2 pulldown (adaptive frame), vertical temporal and static mesh
modes. With a PAL input, inverse 3:2 pulldown is not used.
Input:

AC217A - Intelligent Video Scaler

IF THIS IS YOUR PROBLEM: THEN CHECK TO SEE:
Nothing works/no video output: Are any of the LEDs lit? Is the AC217A plugged into the AC wall outlet?
Is video source connected to the unit and is it putting out a video signal
as viewed on a video monitor?
Is the VCR or video source in the proper mode to output video as
required?
Have you selected the proper input on the unit (COMPOSITE, S-VIDEO
or COMPONENT) for the source selected as the active input?
Is the source of the video ON?
There is video on the output If you are using 5 BNC or RCA connectors to the output display, try
display but it appears out of sync: reversing the H and V sync connectors.
Make sure the display is capable of supporting the resolution you selected
on the front of the unit. Try a lower resolution.
