Introducing Matrox Multi

This chapter lists the Multi

system requirements, and

describes the Multi

documentation.

Chapter 1, Introducing Matrox Multi

Welcome to Matrox Multi

The Matrox Multi family of input/output cards are single-slot SDI cards that

provide up to four independent inputs or outputs to Mac Pro and Apple Xserve

systems. You can install multiple Matrox Multi cards in one system, and

configure each card individually using the Matrox Multi preferences window.

Designed to operate with dedicated third-party applications, Matrox Multi cards

bring a new level of channel density to your Mac system.

Matrox Multi cards feature simultaneous and independent SDI inputs/outputs

that allow you to capture and play back different video formats at the same time.

Multi cards include a 10-bit on-board hardware scaler, and support a full range of

broadcast-quality video/audio inputs and outputs in NTSC and PAL, as well as

480p, 720p, 1080p, and 1080i resolutions at all frame rates. All Multi cards

feature up to 16 channels of embedded SDI audio, four unbalanced analog audio

output RCA connectors for monitoring (not supported on Multi-Ingest), one

analog black burst reference input with loop-through output, one LTC input, and

an RS-422 connector for device control.

Matrox Multi system requirements

Matrox Multi requires a Mac system or Apple Xserve system with the following

configuration:

• Intel-based Mac Pro or Apple Xserve.

• Mac OS X v10.6.7.

• One free PCIe ×8 (electrical) slot or greater.

For up-to-date information about system requirements, check the Matrox Multi

Support section of our website at www.matrox.com/video/support.

Installing Your Matrox Multi

Hardware and Software

This chapter describes how to

install the Multi hardware and

software.

Chapter 2, Installing Your Matrox Multi Hardware and Software

Before you install your Matrox Multi hardware

Read the following information carefully before attempting to install Matrox

Multi hardware.

Start with a functioning system

Before attempting any Matrox Multi installation, you should have a Mac

computer system with Mac OS X fully installed and functioning smoothly. This

will avoid potential problems later on.

Avoid costly damage

Static electricity from your body can damage your Matrox Multi card or your

system. Although you may not notice it, static electricity is generated every time

you move. It’s often too small to cause a spark, but it can still cause damage to

sensitive electronic components or at least reduce their lifespan.

To avoid damage, please observe the following precautions:

• Do not remove your Matrox Multi card from its antistatic bag until you’re

ready to install it. Before removing the card, place the package within easy

reach of the area where you intend to perform the installation.

• You should avoid touching the chips and other components on the circuit

board. Try to handle the card by its edges.

• Try to work in an area where the relative humidity is at least 50%.

• Do not wear wool or synthetic clothing. These fabrics tend to generate more

static electricity than cotton, which is best for this kind of work.

• Turn off the power switches on your system and its connected components.

Once you’ve opened your system, drain static electricity from your body by

touching a bare metal surface on your system chassis before you install or

remove any parts of your system. If you have a grounding wrist strap, use it while

handling and installing any components in your system.

5

Setting the genlock loop-through switch

Matrox Multi features genlock loop-through that lets you use the REF OUT

connector to daisy chain the external genlock reference input (connected to REF

IN) to another device’s reference input. Before installing the Multi card in your

system, set the genlock loop-through switch located on the Matrox Multi card to

either enable genlock loop-through, or disable loop-through by terminating the

reference signal.

If you will connect an external genlock source to Multi’s REF IN connector, and

you plan on using the REF OUT connector, set the genlock switch to

HI-Z. If the

REF OUT connector will not be used, set the switch to

75Ω to terminate the

reference signal.

¦NoteIf the genlock switch is set to HI-Z, you can still terminate the reference

signal by connecting a BNC 75Ω terminator to the REF OUT connector.

Chapter 2, Installing Your Matrox Multi Hardware and Software

Installing your Matrox Multi card

The Matrox Multi card is a three-quarter-length PCIe ×8 card designed to operate

in an Intel-based Mac Pro or Apple Xserve system. You can install multiple

Matrox Multi cards in one system. The maximum number of Multi cards that you

can install depends on the number of suitable PCIe slots in your system. For

detailed instructions on how to perform the following steps, refer to your Mac

Pro or Xserve documentation.

1 Shut down your Mac Pro or Xserve system, unplug the power cord and all

the cables from the unit, and open the Mac Pro or Xserve chassis.

2 Ensure that the genlock loop-through switch on the card is set as desired (see

“Setting the genlock loop-through switch” on page 5).

3 Insert the Matrox Multi card in an available PCIe slot in your Mac Pro or

Xserve, and secure the card into place.

²Caution To avoid damage to the Multi card when installed in an Xserve

system, ensure that the metal mesh gasket around the slot opening on the

Xserve does not bend and make contact with any pins or components on the

Multi card.

4 Close your Mac Pro or Xserve chassis, and reconnect the power cord and all

the cables to the unit.

Installing your Matrox Multi software

You can install the Matrox Multi software on a computer with or without the

Multi card installed. To download and install the Matrox Multi software, visit the

Multi Support section of our website at www.matrox.com/video/support. You can

also contact your Multi dealer for software.

Updating your Multi firmware

When you install the Multi software on a computer with the Multi card already

installed, the software installation automatically verifies the firmware on your

Multi card and updates it if required. However, if you install the Multi software

on a computer without the Multi card installed, your card may have a firmware

version that is not supported by the installed Multi software. Once you install the

Multi card, if it has an incompatible firmware version, a message regarding the

incompatibility between the Multi software and firmware will appear in the

Matrox Multi preferences window, along with a

Launch firmware updater

button.

To update the Multi firmware from the Matrox Multi preferences window, click

Launch firmware updater to run the Matrox Firmware Updater. You’ll be

required to shut down your system to complete the firmware update.

7

Removing your Matrox Multi software

²Caution Do not power off your computer, or interrupt the firmware update

during the update process. Doing so may damage your Multi card.

Alternately, you can update your Multi firmware by running the Matrox

Firmware Updater from the Finder window as follows:

1 Make sure that your Matrox Multi card is installed in your computer (see

“Installing your Matrox Multi card” on page 6).

2 Start your computer.

3 In the Finder menu, choose File > New Finder Window.

4 Choose Applications > Matrox Multi Utilities, and double-click the

firmware updater file to run the Matrox Firmware Updater. You’ll be
