Introduction 1 Introduction Welcome to Kramer Electronics (since 1981): a world of unique, creative and affordable solutions to the infinite 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 350-plus different models now appear in 8 Groups1, which are clearly defined by function.
Your FC-7402 SDI to Analog Converter • • s-video (Y/C) RGsB or YUV1 In addition, the FC-7402: • Includes full ProcAmp control of the video via the front panel and 7-segment display, and via RS-232, with the option to store the settings in non-volatile memory • Has an internal 75% color bar generator, whose timing is based on the SDI input • Encodes 525 line signals to NTSC3.58 or NTSC4.43, and 625 lines to PAL-B, D, G, H, I or Combination PAL-N.

Using Your FC-7402 SDI to Analog Converter 5.1 Connecting the FC-7402 SDI to Analog Converter To connect1 the FC-7402, do the following: 1. Connect the SDI source (for example, a digital camera) to the SDI IN BNC connector. You can also connect (OPTIONAL) the SDI OUT BNC connector to an SDI acceptor (for example, an SDI monitor). 2. Connect the CV OUTPUT BNC connector to a composite video acceptor (for example, a composite video monitor). 3.

Using Your FC-7402 SDI to Analog Converter 5.1.2 Dipswitch Settings Configure the FC-7402 unit by setting the 8 dipswitches, as Table 3 defines: Table 3: Dipswitch Definitions Dipswitch Set as follows: 1 RGB ON for RGB, OFF for YUV 2 VBI ON to enable Vertical Interval Blanking; OFF to disable 3 PEDESTAL2 ON for pedestal (7.5 IRE offset selection for NTSC); OFF for no pedestal 4 4XOVRSMPL ON to enable oversampling ; OFF to disable oversampling For 2 X OVRSMPL (see section 5.1.
Using Your FC-7402 SDI to Analog Converter 5.1.3 Adjusting Oversampling to x2 (Moving Jumper JMP1) Setting DIP 4 ON enables oversampling1, which provides the picture with a better S/N ratio. The default is x4 (recommended). However, you can adjust this factory preset to 2 X OVRSMPL. To adjust oversampling to x2, do the following: 1. Set DIP 4 OFF and remove the power cord. 2. Open the FC-7402 unit and move Jumper JMP1 to the left (see Figure 4). 3.
Using Your FC-7402 SDI to Analog Converter 5.2 Operating the FC-7402 SDI to Analog Converter Operate your FC-7402 via: • The front panel buttons • RS-232 serial commands transmitted by a touch screen system, PC, or other serial controller To operate the FC-7402 using the front panel buttons, do the following: 1. Turn on the power. The signal from the SDI source is automatically converted to composite video, s-Video, and component video (YUV if DIP 1 is set to OFF, or RGB if DIP 1 is set to ON). 2.
Technical Specifications 5.2.2 Locking the Front Panel To prevent changing the settings accidentally or tampering with the front panel, lock your FC-7402. Unlocking releases the protection mechanism. To lock the FC-7402: • Press the PANEL LOCK button (for about 2 seconds) until the PANEL LOCK LED illuminates freezing the front panel controls.
Communication Protocol 7 Communication Protocol1 RS-232 communication between the FC-7402 and the PC is done using the following protocol. The protocol uses four bytes of information, and data is at 9600 baud, no parity, 8 data bits and 1 stop bit. The controller and machine should be connected via a null-modem connection, that is, if using a DB-9 port, connect as follows: Connect pin 5 of the PC to pin 5 of the machine Cross pins 2 and 3, i.e.
Communication Protocol 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.
Communication Protocol CAUTION – this function was designated for development and testing purposes. Improper use of this function may cause erratic behaviour of the machine. INSTRUCTION 11dec – READ EEPROM DATA For sending to machine, DATA = EEPROM sub-address which is to be read. When replying:- DATA = EEPROM sub-address; EXTENDED DATA = requested data. The PC sends this instruction to the machine. The machine replies by sending back the data stored in this sub-address.
