1. Introduction

Thank you for purchasing the DAC-07 Analogue to SD-SDI converter.

The DAC-07 is designed to be an affordable bridge between existing cameras with SD Analogue

Video outputs and SD-SDI equipment or mixers such as the Datavideo SE-900, SE-2800 and

SE-3000.

Due to the nature of SD-SDI signals, single BNC SD-SDI cable runs of up to 100m should be

possible with this unit before the signal would need to be re-clocked or repeated.

The DAC-07 also has the ability to embed two channels of audio (or 1 stereo pair) into the SD-

SDI signal from either unbalanced RCA / Phone connections or balanced 3pin XLR connections.

1.1 Features

Video connections include

• 1x Composite (CVBS), 1x S-Video (Y/C) and 1x Component Y.U.V. (Y,Pb,Pr)

• 2x SD-SDI (BNC) outputs both with embedded 2 channel audio

• SD-SDI output signal that complies with the SMPTE259M-C standard at 270 Mbps

Audio connections include

• Connections for CH1/L and CH2/R on unbalanced RCA / Phone cabling

• Connections for CH1/L and CH2/R on balanced XLR cabling

• 12 and 16 bit audio auto recognition

Others

• Dip switches for video source selection

• Space saving – mountable between camera and tripod plate

• Rugged case design with easy access to Audio and Video connections

• DC 12V / 0.5A input connector with screw locking thread

NB: Ensure the dip switch settings match the video signal being fed into the DAC-07.

Connecting both XLR and RCA / Phone audio sources at the same time is not recommended.

A separate Time Base Corrector may be required if the unit is fed poor AV signals from tape.

Before operating this device please also refer to the section marked SD-SDI Cabling Advice.

4. SD-SDI Cabling Advice

4.1 H o w to avoid problems with SD-SDI

Start with good cabling. BNC cables and connectors are not all made to the same standard. From
the thickness and grade of the centre conductor to the type of dielectric, all these factors
contribute to its impedance, attenuation and Return Loss (RL).

RL is the portion of the transmitted signal that is not admitted to the receiver and is then
reflected back along the cable toward the transmitter (DAC-07). Reflections in the transmission
path will cause attenuation as well as distortion of the signal received. The signal is attenuated
because part of it is reflected back and does not make it to the receiver; it is also distorted
because the reflected signal mixes with the original signal causing it to distort as well as adding
to the noise floor.

A 75 Ohm (Ω) impedance must be maintained throughout the DAC-07 SD-SDI signal/cable path.
Always use patch bays, hubs and repeaters that match the data rate and impedance you are
working with.

Care must also be taken with cable length, as it will affect the error rate in the SD-SDI signal.
Cable lengths beyond acceptable limits will see error rates reach a tipping point and this will
bring about a total loss of picture also known as the Cliff Effect.

Always check with your supplier for cabling advice on the maximum distance for a particular
signal and data rate, in this case an SD-SDI signal that complies with the SMPTE259M-C standard
at 270 Mbps. Datavideo have determined that single BNC SD-SDI cable runs of up to 100m
should be possible with this unit before the signal would need to be re-clocked or repeated.

4.2 H ere is a basic list of other things to avoid

• Do not step on or rest equipment on the cables.

• Do not roll dollies or trolleys over the cables.

• Do not put kinks or sharp bends in the cables.

• Do not exceed the minimum bend radius of the cable.

The general rule for an acceptable bend radius is 10 times the diameter of the cable.

• Cable pulls should be done carefully – do not jerk or stretch the cable(s).

- Do not exceed the cable’s maximum pulling tension. (Call the cable supplier /

manufacturer for this information.)

• Do not pull cable ties too tight on cable looms.

- If you cannot move any cable inside a loom tie, the tie is too tight.

- Put an extra piece of cable in when tightening loom ties - then remove it afterwards

for space.

• Do not put cable management fixings at standard distances apart.

- This can lead to deformity at a given wavelength, which can increase RL.

- Place your loom cable ties at random distances for the same reason.
