2.1 Quick Start

This quick start chart summarizes the basic setup and operation steps.

Overview

3 Overview

The high quality Kramer DigiTOOLS 7508CV/YC to SDI Converter is a

multi-standard converter of analog video (composite and s-Video) to

SMPTE-259M serial digital video (SDI). Many professional video units on

the market today, such as Betacam decks and DVD players have high

quality analog outputs, and the 7508is ideal for preserving the quality, and

minimizing the artifacts, when converting to the digital domain.

In particular, the 7508:

•Converts the SDI on 2 buffered and reclocked SDI outputs

•Automatically detects the input standard (50/60Hz), generating the

appropriate output

•Uses true 10-bit digitizing, making it ideal for the most demanding

applications

•Has an RS-232 port and can be controlled via a user-friendly

Windows®-based program that can modify video parameters such

as contrast, saturation and hue, which may be stored in non-volatile

memory

To achieve the best performance:

•Use only good quality connection cables1

•Avoid interference from neighboring electrical appliances that may

adversely influence signal quality and position your Kramer 7508

away from moisture, excessive sunlight and dust

to avoid interference,

deterioration in signal quality due to poor matching, and elevated

noise levels (often associated with low quality cables).

5 Using Your 7508 CV/YC to SDI Converter

You can use your 7508CV/YC to SDI Converter to convert professional

quality composite video or s-Video (as the example in Figure 2illustrates)

to one or two SDI video outputs.

To convert composite video or s-Video to up to 2 SDI video outputs, do the

following1

1. Connect a composite video source (for example, a VCR) to the CV BNC

INPUT connector.

2. Connect an s-Video source (for example, a camera) to the Y/C 4-pin

INPUT connector.

3. Connect both SDI outputs to SDI acceptors as follows (when only one SDI

output is required, use either of the SDI outputs of the 7508, and leave the

other SDI output unconnected):

•Connect the SDI OUT 1 BNC connector to an SDI acceptor

(for example, an SDI monitor)

•Connect the SDI OUT 2 BNC connector to the second SDI

acceptor (for example, an SDI monitor)

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.

The composite video2or s-Video3

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

signal converts to SDI at both SDI OUT

1 and SDI OUT 2.

5.1).

1 Switch OFF the power on each device before connecting it to your 7508. After connecting your 7508, switch on its power

and then switch on the power on each device

2 To choose the CV input, set the Y/C (DIP 1) OFF

3 To choose the Y/C input, set the Y/C (DIP 1) ON

5.1 Connecting a PC

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 (pin 2 to pin 3, pin 3 to pin 2, and pin 5 to pin 5) to the

RS-232 9-pin D-sub port on the PC.

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

Using Your 7508 CV/YC to SDI Converter

Figure 3: Crossed Cable RS-232 Connection

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.
