Bitfunx OSSC Add-on Board with Composite and S-video Input Linedouble and Smoothing Mode for NTSC PAL Retro Game Consoles Convert composite and s-video signals into component and SCART signals, with smoothing and linedoubler options. It can not only be used in conjunction the OSSC, but can also be used as a standalone converter product on older TVs. Features1) Inputs:Composite, S-video2) Outputs:SCART, Component3)LinedoubleandSmoothingmode4) Support: 240p, 288p, 480i, 576i, 480p, 576p5) Support most of the retro game consoles and some other low-resolution video products6) Auto detect the NTSC, NTSC-443, PAL, PAL-60, SECAM7) Simple operation, two buttons only8) USB firmware upgradable SUPPORTED CONSOLES Supported but not limited to:Atari2600MsxN64NESPlAYSTION1PIAYSATION2SEGA DreamcastSEGA MD1SEGA MD2SEGA SaturnSFCSNESSNK NEOGEOSuper FamicomVic20XBOX BUTTONS, CONNECTORS AND EXTERNAL CONTROLSS-video Input:Connect a S-video (4 pins connector) source to this input, other sources are not supported.AV Input:Standard composite (RCA) connector. You can connect sources such as the Nintendo Super Famicom, Nintendo GameCube, N64 etc.SCART Output:Only output the RGBS signal and audio signal, does not output the component and the composite signal. Can be directly connected to the oc AV1 in (the OSSC SCART interface).Component Video Out:Output the Ypbpr signal, with the audio output interface, can be directly connected to the TVs or the OSSC.Audio Out:Direct acce audio.Input Mode:Switch the input Composite & S-video.DC Jack Socket Power Input:Any decent quality Micro USB charger can be used to power the OSSC add-on board, as its a very efficient device. Also you can use the DC 5.5*2.1mm Power Jack Socket. **Please note that you can only connect to DC 5V.Power Switch:Toggles power off and on.BTN0 (MENU ITEM SELECT):The input button is mainly to select the menu items displayed on the LCD.BTN2 (OPTIONS SELECT):Switch each function corresponding to the menu item.2x/1x Mode:The 2x ON is the standard LINEDOUBLE mode that outputs 480p/576p. This is the mode thats the system defaults to when powered on. The 1x ON simply outputs whatever the input signal is without changing the resolution.Smoothing ON/OFF mode:This mode adds a filtering option to minimize image aliasing for the 480p/576p output.**Please note that the smoothing function only trigger in 2X mode.Output mode:This mode switches the output port of the video.**When the OSSC add-on board was used together with OSSC, OSSC may will not receive the signal in time, resulting in sate of no signal or black screen. At this point, just restart OSSC.USB Input:You can use this USB interface to upgrade your firmware, also you can use this to power the OSSC add-on board.CONNECTING YOUR OSSC ADD-ON BOARD 1) Connect a corresponding source to the composite or S-video input interface.2) Connect to the display or OSSC via SCART or Component output interface.3) Ensure that the USB power or DC power had been connected. Then switch on your OSSC add-on board.4) Select the appropriate video mode through button according to your needs to play the games. PRODUCT FEATURESSignals / Resolutions:The OSSC add-on can accept 240p/480i/288p/576i NTSC/PAL sources to converter to 480p/576p SCART or Component output (480p for NTSC, 576p for PAL). For example, 240p signals are supported properly, allowing for a completely progreive linedouble to 480p. 480i signals are deinterlaced and doubled also to 480p. Keep in mind that the output resolution of this device only up to 480p/576p.Zero Lag:The OSSC add-on board is a zero-lag device, proven using multiple measurements and different devices.Region Compatibility:Both NTSC and PAL signals are supported, but they can not be converted to each other. That means you can plug in whatever signal your target device is compatible with, but NTSC signals might not work on PAL devices, and vice versa.Smoothing Modes:The smoothing mode is completely preference-based, because the average retro-gamer prefers the smoothing mode off for 2D games (SNES, Genesis, etc) and on for 3D games (N64, Saturn, etc). But, the smoothing mode might help reduce flicker with some 480i-only games.Compatibility:Another great feature of the OSSC add-on board is that it outputs a true 480p/60hz or 576p/50hz signal, making it compatible with every device I tested it with! Compatibility is a big iue for retro-gamers, as modern displays arent used to the resolution or refresh rate of these older consoles. This device is an excellent help for streamers who want the highest chance of compatibility.The Pa-through Mode:By putting the OSSC add-on board into pa-through mode (1x mode), incoming composite or s-video signals are simply transparent and convert to into the RBGS/YPBPR (output through the SCART/Component interface). This makes the unit a perfect transcoder to go with 15 kHz displays like PVMs, or of course, the OSSC.HOW TO UPDATE THE FIRMWARE1. Download the firmware programm
