This manual covers the installation, operation, and specifications for the IN1222 / IN1422 Scan Doublers
and the IN1510 / IN1710 Universal Decoders. These four units are virtually identical in operation and
functionality. The main difference between the various models is the output signal scan rate (doubled /
undoubled), the size of the case (1/2 rack or full rack), and the type of connectors used for audio and
video connections. In the IN1510 and IN1710 decoders, the Composite Video or S-Video input signals
are decoded and output as an RGB interlaced video signal at the same frequency as the original signal.
The IN1222 and IN1422 scan doublers first decode the input signal (using the same circuitry as the
IN1510 / IN1710) and then double the number of scan lines. The IN1222 / IN1422 output a noninterlaced RGB video signal at twice the horizontal scan rate of the original input signal. Functions
which apply to the IN1222 / IN1422 but not the IN1510 / IN1710 will be designated in this manual as
IN1222 / IN1422 only. The chart below indicates the major differences between the four models.

DESCRIPTION
The INLINE Scan Doubler / Decoder Series offers advanced decoding and scan doubling capabilities
with the following features:
♦ Universal digital decoding for NTSC, PAL, or SECAM video signals
♦ Digital scan doubling (IN1222/IN1422 only) improves video signals by doubling the number of
scan lines, resulting in a non-interlaced video image output at twice the input signal’s horizontal scan
frequency. The primary benefit of scan doubling is the elimination of visible scan lines, resulting in
a solid, film-like image. Additional benefits include a marked reduction of line flicker and crosscolor interference.
♦ Two Doubling Modes :
Line Doubling - Best for motion video sources, minimizes motion artifacts.
Frame Mode - Best for still video sources, maximizes image detail.
♦ 4 x 1 Video/Audio Switching:
Three inputs for Composite Video / S-Video with stereo audio
One RGB input with stereo audio (passive, no decoding or doubling)
♦ RS-232 control of all parameters
♦ Front panel controls to adjust signal parameters - Hue, Color, Sharpness/Contrast, and Volume.
♦ Gamma Correction - 7 different gamma curves allow compensation for display device
characteristics
♦ Input Memories - users may store a unique set of signal parameter adjustments for each input (Hue /
Color / Contrast / Gamma / Composite Video / S-Video / Volume / Doubled / Undoubled, etc.).
Settings are automatically recalled each time an input is selected
♦ Selectable output sync configuration: RsGsBs, RGBS, or RGBH&V
♦ Horizontal position control (available through RS-232 control in non-doubled mode only)
♦ Disable scan doubling allows the units to function as decoders only (IN1222/IN1422 only).
♦ Digital freeze frame provides rock-solid still video images (IN1222/IN1422 only).
The IN1222/1422 and IN1510/1710 will operate with NTSC, PAL, or SECAM input signals in
composite video or S-video format. For a complete listing of compatible input video standards see page
20. All video and audio input jacks are shown in the diagrams on pages 3, 6 & 7.
Composite Video / S-Video Signals
The IN1222 and IN1510 feature three 4-pin mini-DIN connectors for direct connection of SVideo signals. Composite video signals may be connected to Inputs 1, 2 and 3 by using an
IN9091 adapter (included), which features a female RCA connector for composite video input.
The IN1422 and IN1710 feature three female BNC connectors for composite video input and
three mini-DIN connectors for S-video input, allowing up to six video sources to be connected
simultaneously.
RGB Video Signals
Input #4 on all units is a passive RGB input which will accept virtually any video signal in any format
(the unit will pass up to five signal components).
RGB signals sent into Input 4 are not decoded, doubled, or altered in any way and
simply pass through the unit. This passive input is typically used to hook up a
computer to the doubler/decoder, allowing users to switch between the computer
video input and various composite video or S-video inputs.
The IN1222/IN1510 provide a female 15-pin HD connector for the RGB input.
The IN1422/IN1710 provide a female 15-pin HD connector and 5 BNC connectors for the RGB
input. These two connectors are wired in parallel and only one of them should be used at any
time.
Stereo Audio Signals
All units include a stereo audio input jack for each of the four inputs. The units feature audio-followvideo switching meaning that any time an input is selected, one video signal and its companion audio
stereo pair are simultaneously routed through the doubler/decoder. The audio inputs are unbalanced and
are intended for line level audio signals.
The IN1222/IN1510 feature four 3.5 mm ring-tip-sleeve type female jacks for audio input.
IN9090 adapters (3.5 mm male to 2-RCA female) are included with the unit to facilitate
connection of audio input signals.
The IN1422/IN1710 feature a pair of RCA female jacks for each input (no adapters required).
All INLINE decoders and doublers offer a high quality 24-bit output video signal. The units may be set
to any of the following output signal formats as required: RGBS, RGBHV, and RsGsBs (for information
on changing output sync formats see page 14). The RGB Video and audio output connections are shown
in the diagrams on pages 3, 6 & 7.
The IN1510/IN1710 and the IN1222/IN1422 in interlaced (non-doubling) mode output a signal with the
same scan rate as the input signal. The decoded signal is compatible with many RGB monitors, video
projectors with RGB inputs and will also operate with many LCD projection panels.
The IN1222/IN1422 in non-interlaced (doubling) mode output a signal at twice the original scan rate.
RGB monitors, data projectors, and LCD panels capable of displaying a 31.5 KHz VGA signal (640 x
480 mode) can be used to display the decoded/doubled output signal.
RGB Video Output
The IN1222/IN1510 feature a 15-pin HD female output connector. One IN9045 output adapter
cable (15-pin HD male to 5-BNC male, 12’ long) is included with each unit.
The IN1422/IN1710 feature both a 15-pin HD female connector and 5 female BNC connectors.
The two RGB outputs are wired in parallel and may not be used simultaneously.

Stereo Audio Output
All units route the selected audio signals to the output connector as an unbalanced line level signal. The
output voltage gain varies according to the VOLUME setting for the selected input.
The IN1222/IN1510 feature a 3.5 mm ring-tip-sleeve type female jack for audio output. An
IN9090 adapter (3.5 mm male to 2-RCA female) is included with the unit to facilitate connection
to other audio devices.
The IN1422/IN1710 feature a pair of RCA female jacks for the stereo audio output.
This section offers step-by-step instructions for installing an IN1222/1510 or IN1422/1710. Detailed application
drawings showing all equipment connections are included on pages 6 & 7.
1. Connect the video, audio, and RGB input signals to the appropriate input connectors:
IN1222/IN1510
S-Video signals may be connected directly to Inputs 1, 2 & 3.
Composite video signals may be connected by using IN9091 adapters.
Audio signals may be connected using the IN9090 adapters.
An RGB signal may be connected to Input 4 using an IN8000 Series cable, an IN9045
cable or any other adapter which conforms to the pin outs (see page 15 for pin-out details).
IN1422/IN1710
These units feature one mini-Din connector and one BNC connector for each video input
(Inputs 1 - 3) allowing up to three S-video sources and three Composite video sources to be
connected simultaneously. Please note that there is only one pair of RCA connectors per input
so if two signals are connected to an input, only one may have an audio signal.
An RGB signal may be connected to the 15-pin HD connector or the 5-BNC connectors. These
are wired in parallel and only one of them should receive an input signal.
2. Connect the output signal cable between the scan doubler / decoder output and the display device’s
RGB input using one of the cables listed below. Pin out information is located on page 15.

The IN1222 / IN1510 and IN1422 / IN1710 may be mounted in a standard 19" equipment rack using the
appropriate mounting hardware and procedure listed below:
IN1222 / IN1510 - Use the IN9083 Rack Ears - 1 U high (optional, not included with units). The
IN9083 Rack Mounting kit includes two rack ears and four mounting screws which are slightly longer
than the original case screws.
IN1422 / IN1710 - Use the IN9123 Rack Ears (included with each unit). The IN9123 Rack Mounting
Kit includes two rack ears and six mounting screws which are slightly longer than the original case
screws.
Installation Procedure
The IN1222 / IN1510 and IN1422 / IN1710 are exactly 1 U high without the feet.
If other equipment will be located in the space immediately below the scan doubler /
decoder, the installer may have to remove the feet from the bottom of the case before
mounting the unit in the equipment rack.
5
1. Remove power from the scan doubler / decoder.
2. Remove the case screws and retain for future use.
3. Place the rack ears along each side of the case, aligning the rack ear holes with the holes in
the side of the case.
4. Use the provided mounting screws to attach the rack ears to the scan doubler / decoder case.
5. Mount the unit in a 19" EIA standard equipment rack using standard rack mounting screws.
The shorter original case screws must be used to hold together the case if the rack
ears are ever removed. If the longer screws are used in the case without the rack
ears, they will extend too far into the unit, causing serious damage to the internal
circuitry. This type of damage is not covered under warranty.
