Operation Manual Scan Doubler / Decoder Series IN1222 Scan Doubler IN1422 Scan Doubler IN1510 Universal Decoder IN1710 Universal Decoder ®
1 INTRODUCTION 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.
2 INPUT COMPATIBILITY 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.
3 OUTPUT COMPATIBILITY 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.
4 INSTALLATION 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.
5 RACK MOUNTING 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).

8 OPERATION The IN1222 / IN1510 / IN1422 / IN1710 may be controlled by the front panel buttons or through the RS-232 port. All switching functions and most video / audio adjustment functions can be accessed using the front panel. A few adjustments are available only through RS-232 control (see pages 16 - 19). Using the Front Panel Controls The control panel is divided into three types of control buttons: Input Select Buttons are the four large buttons on the left end of the panel.
9 VOLUME Control Volume levels may be adjusted and stored for each of the four inputs in order to compensate for different audio input levels from the various sources. The volume circuitry is active, allowing the output signal voltage to be set either higher or lower than the original input signal. Press the upper button to increase the volume level or the lower button to decrease the volume level.
10 GAMMA Button Gamma correction is an effective tool used to compensate for the non-linear response of most display devices. The gamma setting may also be changed as required to accomodate the wide variation of video gain and contrast characterstics found in various video program sources. INLINE scan doublers and decoders offer eight different gamma curve adjustments (seven active gamma curves plus no gamma).
11 FREEZE FRAME Button (IN1222 / IN1422 only) The FREEZE FRAME button may be used to store and view a single video frame. The digital freeze frame offers a perfectly still image of a single video frame for extended study or presentation purposes. This provides a much better image than the freeze frame feature found on most VCRs. Each time the FREEZE FRAME button is pressed it toggles the unit between Freeze Frame or normal motion video. Freeze Frame is engaged when the LED is on.
12 SCAN DOUBLING PRIMER Garden variety composite video or S-Video images are interlaced, meaning that the picture information from each video frame is split into two fields. Field one contains all of the odd horizontal lines and Field two contains all of the even horizontal lines. Each field is displayed for only 1/60 of a second, so the human eye actually merges all the odd and even lines from the two fields into a single image which is refreshed completely 30 times a second (timings are for NTSC).
13 Selecting Doubling Modes (IN1222 / IN1422 Only) The following procedure will allow users to select and store the desired doubling mode (or disable doubling) for Inputs 1, 2, and 3. 1. Turn the unit power on. 2. Select the desired input channel and make the necessary installation adjustments. 3. Hold down the appropriate front panel button (see chart below) continuously for 3 seconds until the button LED flashes twice. This indicates that the doubling method has been changed for that input.
14 POWER ON ADJUSTMENTS The IN1222 / IN1510 / IN1422 / IN1710 utilize "Power On" settings to control two setup parameters. In order to access a Power On adjustment, the user must hold down the indicated button continuously while toggling the unit’s power switch to "ON" (if power is already on, the user can hold down the indicated button and switch the power off and then back on).
15 UNIVERSAL POWER SUPPLY The IN1222 / IN1510 / IN1422 / IN1710 employ a universal (switch mode) power supply which automatically adjusts to accept input voltages worldwide. Input voltage can range between 96V and 260V AC and frequency may range from 50 Hz to 90Hz. The power entry module uses an IEC standard male connector for power connection. U.S. domestic units are shipped with a standard IEC female to Edison male power cable.
16 USING RS-232 CONTROL The IN1222/IN1510 and IN1422/IN1710 include an 9-pin REMOTE CONTROL port which will accept serial commands from a control system, computer serial port, or any other device capable of sending out serial ASCII commands at compatible baud rates. All switching, adjustment, and set-up parameters can be controlled using RS-232 commands.
17 COMMAND CODE STRUCTURE All commands sent to the unit must contain a leading code, the command code, and an ending code. Each command must be completely executed before the unit will accept a new command. When a command is completed, the unit provides a response code; "OK" indicates the command was received and executed, "ERR" indicates there is a problem with the code and the command was not executed.
18 RS-232 ASCII CODES The table below lists the ASCII control codes for the IN1222 / IN1510 / IN1422 / IN1710. These are virtually identical to the codes used with the IN1240 / IN1540, and new codes for the current version are indicated by an asterisk (*). The most current version of firmware as of this writing is V1.4a.

24 The video image on the screen is magenta colored and very noisy. The unit may be set for "SECAM Enabled". Verify that the unit is set to the proper decoder format. If the unit has been set to the "SECAM Enabled" mode and the input signals are NTSC or PAL, switch back to the "SECAM Disabled mode" (see page 10). When power is applied to the unit all LEDs flash continuously. The unit has an internal hardware problem. Call your INLINE dealer to arrange for repairs.
