Introduction 1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, and presentation professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 500-plus different models now appear in eight groups1 that are clearly defined by function.
Overview 3 Overview The high quality FC-7501 is a multi-standard converter that converts professional quality video to serial digital video (SDI). The following analog formats are supported: Composite video s-Video Component video (Y, B-Y, R-Y, sometimes called YUV or Y, Pb, Pr) The FC-7501 maintains the high level of professional video quality, prevalent with component video output devices and DVD players, when converting to SDI.
Your Analog Video to SDI Converter Caution – No operator-serviceable parts inside unit. Warning – Use only the Kramer Electronics input power wall adapter that is provided with this unit1. Warning – Disconnect power and unplug unit from wall before installing or removing device or servicing unit.

Using Your Analog Video to SDI Converter 5. Turn on the power and press the COMP. (Component video) button. The component video signal converts to SDI at both SDI OUT 1 and SDI OUT 2.
Upgrading the FC-7501 to an FC-7501P 6 Upgrading the FC-7501 to an FC-7501P You can improve the SDI Pixel Jitter by converting the FC-7501 to an FC-7501P (an Analog Video to SDI Converter with very low jitter), as explained in the following steps. 6.1 Inserting the 7501M Module 1. Unfasten the two pairs of screws on each side of the cover of the FC-7501 and remove the cover, as Figure 3 illustrates: Figure 3: Removing the Cover of the FC-7501 2. Remove jumpers on J7 and J8 (see Figure 4.) 3.
Upgrading the FC-7501 to an FC-7501P Figure 4: Upgrading the FC-7501 to FC-7501P by inserting an optional 7501M module 4. Replace the cover on the FC-7501, and secure it in place by fastening the two pairs of screws on each side of the cover. The FC-7501P is an upgraded FC-7501 unit (with the 7501M added).

Communications Protocol for the FC-7501 This protocol complements Kramer’s “Protocol 2000” (Kramer’s switcher protocol), so the two protocols can co-exist without disturbing one another. (According to Protocol 2000, the FC-7501 appears as machine number 22, so care should be taken not to set a switcher with this machine number).
Communications Protocol for the FC-7501 8.1 Description of Instructions INSTRUCTION 0 – RESET DATA=0: initialize the machine. When the machine is initialized, it will send the RESET code (DATA = 0). If the machine receives this code, it will reset to its “power-up” state. DATA=1: configure the machine to its factory default state. When the machine receives this code, all programmable parameters will be reset to their factory-default values. EXTENDED DATA - set as 0.
Communications Protocol for the FC-7501 INSTRUCTION 12 – WRITE I²C DATA = I²C sub-address; EXTENDED DATA = data to be written to this sub-address. The PC sends I²C data (to the I²C address which was last accessed via INSTRUCTION 13). The machine replies by sending the same data back to the PC. CAUTION – this function was designated for development and testing purposes. Improper use of this function may cause erratic behavior of the machine.
