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.

The 7408 features:

•Reclocked and equalized SDI output (loop)

•4 times digital over sampling to minimize digital artifacts

•Output configuration to Composite Video and s-Video (Y/C), or

component video (YUV)

•User-friendly Windows PC software, provided for ProcAmp

control via RS-232 for adjusting parameters such as contrast, hue,

saturation and sharpness

•NTSC encoding with or without a 7.5IRE setup

•A perforated cover to prevent overheating

To achieve the best performance:

•Connect only good quality connection cables, thus avoiding

interference, deterioration in signal quality due to poor matching,

and elevated noise levels (often associated with low-quality cables)

•Avoid interference from neighboring electrical appliances that may

adversely influence signal quality and position your Kramer 7408

away from moisture, excessive sunlight and dust

PROGRAM

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 following1:

1. Connect the SDI source (for example, a digital camera) to the SDI

IN BNC connector. You may also connect the SDI OUT BNC

connector to an SDI acceptor (such as an SDI monitor).

2. Connect the following:

An s-video acceptor (such as an s-video monitor) to the C−Y

output BNC connectors; and/or,

A composite video acceptor, such as a composite video monitor

to the CV output BNC connector; or,

A component video acceptor, such as a VCR, to the YUV BNC

connectors

3. Connect a PC (if required) to the RS-232 port (see section 5.2).

4. Set the DIP-switches, as section 5.2 describes.

5. Connect the 12V DC power adapter to the power socket and

connect the adapter to the mains electricity.

Warning:

Do not cover the 7408

1 Switch OFF the power on each device before connecting it to your 7408. After connecting your 7408, switch on its power

and then switch on the power on each device

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.

Method A (Figure 3)—Connect the RS-232 9-pin D-sub port on the unit via

a crossed cable (only pin 2 to pin 3, pin 3 to pin 2, and pin 5 to pin 5 need

be connected) to the RS-232 9-pin D-sub port on the PC.

Note: There is no need to connect any other pins.

Figure 3: Crossed Cable RS-232 Connection

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 null-

modem adapter to the RS-232 9-pin D-sub port on the PC. The straight

cable usually contains all nine wires for a full connection of the D-sub

connector. Because the null-modem adapter (which already includes the

flow control jumpering described in Method A above) only requires pins 2,

3 and 5 to be connected, you are free to decide whether to connect only

these 3 pins or all 9 pins.

5.3 Setting the DIP-Switches

Configure the 7408 unit by setting the DIP-switches, as Table 2 defines:

Table 2: Setting the DIP-switches

DIPS Function Description

1 PROGRAM ON for upgrading firmware; otherwise OFF

2 VBI ON to enable Vertical Interval Blanking; OFF to disable

3 PEDESTAL1ON for pedestal (7.5 IRE offset selection for NTSC); OFF for no pedestal

4 4XOS2ON to enable oversampling3; OFF to disable oversampling

5 NTSC ON for NTSC 3.58 (see Table 3)

6 PAL ON for PAL (see Table 3)

7 AUTO ON for multi-standard; OFF for user selected (fixed) standard (see Table 3)

8 COMPONENT ON for component video; OFF for composite video and/or s-video

1 NTSC offsets the black level within the active video signal by 7.5 IRE when selected

2 4xOS is 4 x Oversample

3 When this method is used, the noise figure is improved
