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, presentation, and broadcasting professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 1,000-plus different models now appear in 11 groups 1 that are clearly defined by function.
Getting Started 2.1 Quick Start This quick start chart summarizes the basic setup and operation steps.
Overview 3 Overview The Kramer DigiTOOLS 7408 SDI to Analog Converter is a high quality, full 10-bit SDI to Analog video converter in a Kramer Tool housing. The 7408 SDI to Analog Converter is a multi-standard unit, converting 525-line SDI to NTSC or NTSC4.43, and 625-line SDI to PAL-B/D/G/H/I/N.

Using Your 7408 SDI to Analog Converter 5 Using Your 7408 SDI to Analog Converter You can use your 7408 SDI to Analog Converter to convert SDI video to professional analog video: composite video and s-Video, or component video (as the example in Figure 2 illustrates). 5.1 Connecting Your 7408 SDI to Analog Converter To connect the 7408, do the following 1: 1. Connect the SDI source (for example, a digital camera) to the SDI IN BNC connector.
Using Your 7408 SDI to Analog Converter Figure 2: Connecting a 7408 SDI to Analog Converter 5.2 Connecting to the 7408 via RS-232 You can connect to the unit via a crossed RS-232 connection, using for example, a PC. A crossed cable or null-modem is required as shown in method A and B respectively. If a shielded cable is used, connect the shield to pin 5.
Using Your 7408 SDI to Analog Converter Hardware flow control is not required for this unit. In the rare case where a controller requires hardware flow control, short pin 1 to 7 and 8, and pin 4 to 6 on the controller side. Method B (Figure 4)—Connect the RS-232 9-pin D-sub port on the unit via a straight (flat) cable to the null-modem adapter, and connect the nullmodem adapter to the RS-232 9-pin D-sub port on the PC.

Communication Protocol (Ver 0.1) 7 Communication Protocol (Ver 0.1) RS-232 communication between the 7408 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 (Ver 0.1) 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.
Communication Protocol (Ver 0.1) 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.
