CHAPTER 1: Getting Started

Welcome to the world of HAL!

To help you get started with the installation of the HAL System, we have provided a simple breakdown of the key
installation tasks—presented in the recommended order. If you are new to the HAL System, we recommend that
(after reviewing this workflow) you spend a few moments reviewing the basics of the system before actually begin­ning the installation. We understand that your job is to get this system installed as quickly and efficiently as pos­sible, but a slight detour to review the product details is well worth your time. See "Introduction to the HAL
System" on page 4.

The Installation Workflow

There are seven key tasks involved in the installation of a HAL System. An overview of each task is listed below,
along with page references to the specific details for each task. We recommend that you review this entire list to
get a sense of the work flow, and then return to the first task to begin the actual installation process. Note that the
order of some of these tasks can vary. See each task description for more details.

Task 1: Install and connect the HAL.

This task involves the physical attachment of the HAL hardware to your audio rack. You can perform this task off­site or on-site. Once installed, you then connect other devices to the HAL and, if necessary in your environment,
connect the HAL to your Ethernet network. If you are installing onsite, you may want to pull and terminate the
shielded CAT 5e cabling first (see "Task 3: Pulling and Terminating shielded CAT 5e Cabling" on page 76) so
that the cables are ready to connect to the HAL. For details on installing the HAL, see "Task 1: Install and Con­nect HAL" on page 72.

Task 2: Configure the system.

Before the system can function properly, you must configure the hardware (the HAL, EXPs, RADs, and DRs) as
well as the audio processing and path. You perform this configuration using the Halogen software that is shipped
with the HAL hardware. (The software is also available on the Rane website at rane.com/hal.) You can configure
the system by loading a configuration file that contains the appropriate hardware settings, audio flow, and proc­essing; or you can create the configuration directly on a live device. We strongly recommend using a con-
figuration file as a starting point!

In most cases, the audio designer will have already created this configuration file, which makes your installation
job much easier. All you have to do is load the file into the HAL device. For the purposes of this guide, we have
assumed this scenario—that the configuration file has already been created for you. If not—well, you’re going to
need to do a little more reading. You can find additional information about configuration files in the Halogen
Help System (accessed from the Halogen software) as well as in the HAL System Design Guide (available on your
product DVD as well as on the Rane website).

NOTE: If the final configuration is to be completed later, but you merely want to install the equipment and

make sure the system can send and receive audio, you can create a very simple configuration to accomplish
this. See "Creating a Verification Configuration" on page 85 for more information.

Regardless if you’re creating a new configuration or simply loading a pre-defined configuration, you will need to
install, start, and use the Halogen software.

1

HAL SYSTEM INSTALL GUIDE

NOTE: Where this configuration task falls in the installation process is somewhat flexible. If you prefer, you

can install and connect the RADs, DRs, and EXPs prior to loading the configuration file. There are advan­tages, however, in loading the configuration first. Whether or not the configuration is loaded, as long as the
HAL is powered on and connected prior to installing the peripheral devices, you can determine immediately
upon installing a RAD, DR, or EXP (by observing its status indicators) if it is functioning properly. But if
the configuration is also in place, you can immediately determine if the EXP, RAD or DR model you just
installed matches the model specified in the HAL configuration (if there’s a mismatch, the EXP's front panel
LED's flash, the RAD’s LEDs flash red and the DR's LCD screen displays Configuration Mismatch). Also, if
you have wireless access to the HAL, loading the configuration file early in the process makes it possible to
then view the configuration from a laptop as you’re installing the RADs, DRs, and EXPs. If you do not have
a configuration file and you plan to simply test that the installed equipment can successfully send and
receive audio, disregard this recommendation. You will create a simple test configuration after you have
installed all of the equipment.

Task 3: Pull and terminate the shielded CAT 5e cabling for the EXPs, RADs and DRs.

Each EXP, RAD and DR connects to the HAL via a shielded CAT 5e cable. We recommend pulling this cable
prior to installing the RADs and DRs. Doing so makes it much easier to troubleshoot their installation. Note that
each RAD and DR requires a home run. As noted in the previous task, if the shielded CAT 5e cables are installed
and terminated, and the HAL is powered on and connected, you can verify if the RADs and DRs are working prop­erly as soon as you connect them. For details on this task, see "Task 3: Pulling and Terminating shielded CAT 5e
Cabling" on page 76.

Task 4: Install and connect HAL Expansion Units (if needed).

If your system requires one or more Expansion Units (EXPs), you should install and connect them to the HAL
before beginning the installation of your Remote Audio Devices (RADs) and Digital Remotes (DRs). This task
involves using shielded CAT5e cable to connect each EXP in a daisy-chained fashion. That is, connecting the
first EXP to HAL, connecting the second EXP to the first EXP, and so on. For details, see "Task 4: Installing and
Connecting HAL Expansion Units" on page 76. It is important that you install the correct EXPmodel in each loca­tion and in the correct order in the daisy-chain. If you load the HAL configuration prior to installing the EXPs,
you can view the status indicators to determine if you have installed the correct model. If the models do not match,
the front panel LEDs on the EXP flash. You can also see this status in Halogen's Hardware Workspace.

The older HAL1 system used a FireWire based expansion bus. This bus allowed you to connect up to four EXP1
expansion units in a daisy-chained manner. For details see "Task 4 (legacy): Installing and Connecting HAL1
Expansion Units" on page 1.

Task 5: Install and connect the individual RADs and DRs.

This task involves the connection of the RADs and DRs to the shielded CAT 5e cable, followed by the physical
installation of the RADs and DRs into the switchboxes in the wall. A key part of this task is to double-check that
you are installing the correct RAD and DR models in each location. The wiring diagram should specify which
RAD and DR models go in which locations. Also, if you load the HAL configuration prior to installing the RADs
and DRs, you can view the RAD and DR status indicators to determine if you have installed the correct model. If
the models do not match, the bottom four LED indicators on the RAD flash red, while the DR LCD screen dis­plays Configuration Mismatch. In addition to verifying that you’ve installed the correct model, this task involves
the verification that the RAD and DR hardware is communicating properly with the HAL. Again, the RAD and
DR status indicators provide this information. For details, see "Task 5: Installing and Connecting RADs and DRs"
on page 78.

CHAPTER 1: Getting Started

Task 6: Install and connect all analog devices.

This task needs little explanation and is here simply to suggest where in the workflow we recommend the instal­lation and connection of analog devices. The HAL and some EXPs provide you with analog inputs and outputs.
You know what to do with them!

Task 7: Verify connections, perform audio test, troubleshoot, and save the final con­figuration.

After installing the HAL, EXP device(s), RADs, DRs, connecting any other analog devices, and loading the con­figuration file, you need to verify that everything is working properly. See "Task 7: Verify and Troubleshoot Instal­lation" on page 83.

NOTE: If you do not have a pre-defined configuration file but you want to verify that the hardware is work-

ing, you need to create a simple verification configuration. See "Creating a Verification Configuration" on
page 85 for more information.

You’ll be happy to learn that Rane has taken much of the guesswork out of the verification process. Although you
will review the status indicators on the HAL, EXPs, RADs, and DRs at the time you install these components, we
recommend double-checking these indicators in the final verification task. There are three primary sources of infor­mation to help you quickly troubleshoot any problem:

1. RAD LEDs and DR LCD screens: By simply viewing the LEDs on the front of a RAD and the DR LCD
screen, you can see immediately if the device is receiving power, if its data communications connection is
working, and if its model matches the model configured for the port to which it is attached. With a RAD,
you can also see if it's transmit (Tx) and receive (Rx) functionality is working, if it is actively receiving an
audio signal, and if its audio signal is overloading.

2. HAL LEDs: LEDs on the HAL provide power and signal information for all the connected RADs and
DRs as well as information about the Expansion Bus and Ethernet network (if applicable).

3. EXP LEDs: LEDs on the EXPs also provide power and signal information for all the connected RADs
and DRs as well as information about the Expansion Bus.

4. Halogen messages: After the configuration file is loaded into the HAL, you can use Halogen to deter­mine if you installed the appropriate RADs and DRs in each location or if a RAD or DR is configured
incorrectly. The software displays color-coded messages telling you of any problems. The software also
contains the configured audio flow, which you should examine if there are audio problems that cannot be
traced to a hardware issue. It’s possible that something in the audio flow (in Halogen's Processing Work­space) was configured incorrectly.

When you have completed the installation, fully tested the system, and feel confident that the configuration is
accurate, SAVE AND BACK UP THE CONFIGURATION FILE! If you or someone else inadvertently (or even
deliberately) changes configuration settings on a live device and, as a result the system stops working, you will be
very happy that you have a backup. For more details, see "Save the Final Configuration File" on page 85.

Now, on with the installation (after reviewing the basics of the system, of course!).

HAL SYSTEM INSTALL GUIDE

Introduction to the HAL System

The HAL System, Rane's revolutionary new audio product, makes it possible for you to solve age-old audio issues
with a simple click or two (or sometimes three). In designing this system, Rane's engineers have anticipated the
needs of the installer, the designer, and the end user, resulting in an intuitive and relatively simple system to oper­ate. You'll be amazed at how quickly you can accomplish tasks that used to take hours.

The HAL System includes both hardware and software components. This system introduction provides a broad
overview of these components.

Hardware Components

The primary hardware component in a HAL System is the HAL host device. There is only one HAL device per sys­tem. HAL serves as the system's brain to which you connect other slave devices such as analog audio equipment,
Remote Audio Devices (RADs), Digital Remotes (DRs), Expansion Units (EXPs), and more. Inside HAL is a DSP
processor that manages the audio as well as a host processor that manages other aspects of the system.

The following graphic provides a visual of an entire HAL1x System:

CHAPTER 1: Getting Started

HAL SYSTEM INSTALL GUIDE

Software Component

Included in the HAL System is a software application, called Halogen, that you use to configure and manage the
entire system. Halogen contains two primary graphical workspaces, the Hardware Workspace and the Processing
Workspace, in which you simply drag and drop hardware components and processing blocks to set up the audio
system you want. You can work in online mode (connected to HAL) or offline mode (not connected to HAL or
any other hardware). The ability to work in offline mode makes Halogen a powerful design tool available for use
whether or not you have the hardware in hand. And not only can you design your system without having hard­ware in place, you can also test your system before you install the hardware! Now that's powerful!

NOTE: When working in online mode, changes made in the software are immediately implemented and saved

to HAL (with the exception of DSP changes that require a system recompile).

Below is a sample of the Halogen Processing Workspace:

For more details on the Halogen software application, see "Introduction to the Halogen Software" on page 87.

System Requirements

To use a HAL System, the following items are required:

l

You must have access to a computer running Microsoft Windows 7 or greater. The computer must also have
an Ethernet port, which you use to connect the computer to the HAL device (either directly or via an Eth­ernet network via a shielded CAT5e cable). This connection is necessary for using the Halogen software to
load configuration information into the device and also for monitoring detailed status information. Note that
some status information is visible on the hardware itself.

l

You must have administrative rights to install the Halogen software, but you do not need administrative
rights to run the software.

l

Most RADs require two, three, or four-gang standard switchboxes (for installation into a wall). A DR1
requires a one-gang switchbox, while a DR2 and DR3 require two-gang switchboxes. Switchboxes used for
both RADs and DRs must have a minimum depth of 2 1/4" (57 mm).

These ports are listed from the PC's perspective to aid in configuring the PC's firewall so that RaneLink and Hal­ogen can communicate with HALhosts on your network.

HAL devices send occasional UDP broadcast messages. The RaneLink II service on the PC listens constantly for
these messages and when it receives one, it does three things, if necessary:

l

Sets up a temporary link-local IP address (in other words, the address is cleared when the computer reboots)
on the appropriate network interface card (NIC).

l

Adds an entry to the computer's network route table. RaneLink II maintains the list of HAL devices and it
must be running for Halogen to communicate with a HAL, even if the HAL has been located by a manual
search.

l

Opens and maintains a TCP connection with HAL so that it can receive status updates.

CHAPTER 2: Hardware Component Details

This chapter provides details about the HALSystem hardware devices that you'll be installing.

Overview of HAL Devices

The HAL host device (which is referred to as HAL throughout this guide) is the brain that controls the entire
HALSystem. It can connect to a variety of other hardware (or slave devices) such as analog equipment, RADs,
DRs, and EXPs. Inside the HAL hardware is a DSP audio processing engine and a host controller that controls
DSP operations and manages control links, presets, and more. There is only one HAL device per system. You can­not connect one HAL to another.

NOTE FOR DRAG NET USERS: The DSP processing engine in the HAL1 device is four times more powerful

than the RPM88, the HAL2 has twice the power as the RPM88, and the HAL3, HAL3s, and HAL4 have
the same amount of DSP processing power as the RPM88.

Other Functionality

In addition to hosting other hardware devices and managing system operations, HAL also does the following:

l

Provides power to connected RADs, and DRs

l

Stores configuration settings and compatible firmware for itself and for each connected RAD, DR, and EXP

l

Provides a connection to an Ethernet network (for control of HAL and the connected devices)

l

Displays various status indicators (LEDs) providing information about the health of the system

CHAPTER 2: Hardware Component Details

1. The Power IEC jack connects to AC line voltage, 100-240 VAC, 50/60 Hz.

2. Fault, Locate, and Power LEDs

The Fault LED (red) turns on when something in the hardware goes awry. The first step in trou­bleshooting the problem is to open the Halogen software and check the status of this HAL device.

The Locate LED flashes green when you place this HAL device in Locate Mode (via the Halogen soft­ware). The purpose of this Locate functionality is for verification, when working in the software, of the
physical device you are configuring or viewing.

The Power LED lights when the HAL hardware is powered on.

3. Ethernet port and LAN and Link LEDs

Use this port to connect HAL to an Ethernet switch or directly to a computer.

15

HAL SYSTEM INSTALL GUIDE

NOTE: This Ethernet port contains auto-MDIX functionality, which means that you can use either a

standard Ethernet cable or a crossover cable to connect to a computer or Ethernet switch. The auto­MDIX functionality takes care of coordinating the proper connection between the devices.

The Ethernet LAN LED flashes when HAL detects any Ethernet packets on the network. The Link LED
indicates if the Ethernet network is connected. If HAL is connected to an Ethernet network but the Link
LED is off, there is likely a problem with the connection.

4. Expansion Bus LED and CAT5e port

Use the Expansion Bus port to connect an Expansion Bus device (such as an EXP1x) to the HAL via a
shielded CAT 5e cable. To attach additional Expansion Bus devices to your HAL System, use a shielded
CAT 5e cable to connect each new device to the previous device—in a daisy chain style.

If lit, the Expansion Bus Link LED indicates that the Expansion Bus device is communicating properly
with HAL. If an Expansion Bus device is properly connected to the port yet the status LED remains dark,
there is likely a problem with the connection.

5. Digital Remote Device ports

Use these ports to connect each DR to the HAL via a standard shielded CAT 5e (or better)cable. You
must use a shielded Ethernet cable for this connection. If you need more DR connections than the number
of DR ports that the HAL provides, you can use a RAD port to connect a DR.

6. Remote Audio Device ports

Use these ports to connect each RAD to the HAL via a standard shielded CAT 5e (or better)cable. You
must use a shielded Ethernet cable for this connection. If you need more RAD connections, you will need
to connect an Expansion Unit with RAD ports (such as an EXP1) to your HAL device. You cannot con­nect a RAD to a DR port.

7. Digital Remote Device LEDs

Provides information about the health of the shielded CAT 5e connection between each DR and HAL.
The numbers correspond to the DR ports in the lower area of the rear panel. The Comm LED (on the top
row) lights solidly if the DR's data communications pair is working properly. The Power LED (on the bot­tom row) lights solidly if HAL is supplying adequate power to the DR port.

8. Remote Audio Device LEDs

Provides status information about the health of the shielded CAT 5e connection between each RAD and
HAL. The numbers correspond to the RAD ports in the lower right corner of the rear panel. For example,
the LEDs for number 1 provide information about the RAD connected on port 1. Each LED corresponds
with one twisted pair within the shielded CAT 5e cable. If the twisted pair is functioning properly, the
LED displays a solid green light when the HAL is programmed to expect the RAD model that is phys­ically plugged in. When all cable pairs are working properly, but HAL is not yet programmed for the con­nected RAD model, all four LEDs flash red. Note that flashing red is a good thing: the cable’s good – just
program HAL and you’re done.

l

Audio Rx LED—lights solidly if the HAL receive pair is working properly.

l

Audio Tx LED—lights solidly if the HAL transmit pair is working properly.

l

Comm LED—lights solidly if the RAD's data communications pair is working properly.

l

Power LED—lights solidly if HAL is supplying adequate power to the RAD port.

16

CHAPTER 2: Hardware Component Details

NOTE: The Remote Audio Device LEDs on the front panel differ from those on the rear panel. The

front panel LEDs provide information about signal activity on each audio channel. See the "Over­view of HAL Devices" on page 13 for more details.

TIP: You can use the Remote Audio Device LEDs on the rear panel and on the RAD to trou-

bleshoot connection problems. See "Troubleshooting the HAL Hardware" on page 101 and "Trou­bleshooting RAD Devices" on page 103 for details.

9. Relay Out ports

Reed relay ports used to signal another device. A common implementation is to link a relay port to a Tog­gle control so that an end user can change its value. Also, the Halogen software contains a checkbox for
each relay port, the value of which you can include in a preset or link to another control, making it pos­sible to use a preset or control to turn the relay port on or off.

10. Logic In ports

Use these TTL 5-volt digital logic input ports to communicate to the HAL System via an external control
device. You can configure each Logic In port to control a selector, toggle, or command within the HAL
System. For example, you might use a Logic In port to select between two audio channels, or to mute the
whole system.

11. Mic/Line Input ports

Use these ports to connect analog microphones or line input devices. Note that the Mic In ports support
phantom power.

12. Line Output ports

Use these ports to connect analog line output devices, such as amplifiers or powered speakers.

13. AES3 ports

Use these ports to connect AES3 inputs and outputs to the HAL. The HAL2 supports one input port and
one output port using standard XLR connectors. Each AES3 port provides two digital audio channels.

14. IRRemote ports

Use these ports to connect each IR Remote to the HAL via a standard shielded CAT 5e cable. You must
use a standard Ethernet cable for this connection.

15. Mic/Line-Plus Input ports

Use these ports to connect microphone, balanced or unbalanced line input devices. When configured in
Halogen for Condenser Mic, each input provides +48 V phantom power and 18 dB input gain. When Con­figured for Dynamic Mic, each input provides 30 dB input gain. When configured in Halogen for bal­anced, each input is +4 dBu balanced. When configured for unbalanced, each input is -10 dBV
unbalanced, with left and right channels summed to a single mono input.

17

HAL SYSTEM INSTALL GUIDE

Front Panel Description

1. Mic/Line Input LEDs

Provides status information about mic/line analog inputs connected to the HAL. The numbers correspond
to the mic/line input ports on the rear panel.

These LEDs provide information on the following:

l

Overload LED (red) – indicates that the mic/line input is experiencing a signal overload

l

Signal LED (green) – indicates the presence of an audio signal on the mic/line input

2. Mic/Line-Plus Input LEDs

18

CHAPTER 2: Hardware Component Details

Provides status information about mic/line-plus analog inputs connected to the HAL. The numbers cor­respond to the mic/line-plus input ports on the rear panel.

These LEDs provide information on the following:

l

Overload LED (red) – indicates that the mic/line-plus input is experiencing a signal overload

l

Signal LED (green) – indicates the presence of an audio signal on the mic/line-plus input

3. Line Output LEDs

Provides information about HAL analog outputs. The numbers correspond to the line output ports on the
rear panel.

These LEDs provide information on the following:

l

Overload LED (red) – indicates that the line output is experiencing a signal overload

l

Signal LED (green) – indicates the presence of an audio signal on the line output

4. Digital Remote LEDs

Indicates which Digital Remotes are enabled. Each numbered LED corresponds to the Digital Remote port
with the same number. If a Digital Remote is connected on a port but its Enabled LED is off, there is
likely a problem with the shielded CAT 5e connection or with the Digital Remote itself. If an Enabled
LED is flashing, it indicates that the physical Digital Remote model does not match the Digital Remote
model specified for this port in the HAL configuration.

5. Remote Audio Ports status indicators

Provides information about the RAD audio channels. The numbers at the top of the front panel correspond
to the RAD ports on the back of the HAL. For example, the LEDs for number 1 provide information
about the RAD connected on port 1.

Under each RAD number are LEDs for four audio channels, two input and two output. These four LEDs
represent the maximum number of channels a RAD is capable of transporting. However, not all RAD mod­els use all four channels. For example, the RAD1 model provides two microphone inputs, so only the two
columns of indicators labeled IN would be active.

These LEDs provide information on the following:

l

Overload LED (red)–indicates that the channel is experiencing a signal overload

l

Signal LED (green)–indicates the presence of an audio signal on this channel

l

Enabled LED (yellow)–indicates the availability of the associated audio channel. If a RAD is con­nected on this port and all Enabled lights are off, this indicates a problem with the shielded CAT
5e connection or with the RAD. If the Enabled LEDs are flashing, this indicates that the physical
RAD model does not match the RAD model specified for this port in the HAL configuration.

6. The Ethernet Comm and Link LEDs

Provides status information about the HAL Ethernet connection.

l

Comm LED (yellow) – flashes when HAL has been discovered by at least one PC running Rane­Link II1, is solid when Halogen is exclusively connected to HAL, is off when HALhas yet to be

discovered.

1

A service needed by Halogen to establish a connection with HAL.

19

HAL SYSTEM INSTALL GUIDE

l

Link LED (green) – indicates if the Ethernet network is connected. If the HAL is connected to an
Ethernet network but the Link LED is off, this indicates a problem with the connection.

7. The Expansion Bus LED

If lit, indicates that an Expansion Bus device is properly connected to the HAL. If an Expansion Bus
device is properly connected to the port and powered on yet the status LED remains dark, there is likely a
problem with the connection.

8. Fault, Locate, and Power LEDs

The Fault LED (red) turns on when something in the hardware goes awry. The first step in trou­bleshooting the problem is to open the Halogen software and check the status of this HAL device.

The Locate LED flashes green when you place this HAL device in Locate Mode (via the Halogen soft­ware). The purpose of this Locate functionality is for verification, when working in the software, of the
physical device you are configuring or viewing.

The Power LED lights when the HAL hardware is powered on.

9. AES3 LEDs

Provides information about the AES3 digital audio channels. The numbers at the top of the front panel cor­respond to the AES channels on each port, two for the input port and two for the output port.

The Lock LED (yellow) indicates when the AES3 input port is locked to the attached AES3 output
device.

Under each AES3 channel number are LEDs for that channel's audio, providing information on the fol­lowing:

l

Overload LED (red)–indicates that the channel is experiencing a signal overload

l

Signal LED (green)–indicates the presence of an audio signal on this channel

Discontinued HAL Models

This section describes HAL models that are no longer in production. For the most current list of HAL models, see
the Rane website. Data Sheets for discontinued models may also be downloaded from the Rane website.

The following devices are no longer available: HAL1, EXP1, and HAL3.

While Rane no longer produces the HAL3, Halogen software continues to provide support for this product, allow­ing customers to:

l

Connect to HAL3 devices

l

Open existing HAL3 configurations

l

Build new HAL3 configurations

To build a new HAL configuration with a discontinued HAL, see Creating Configurations with Discontinued
HAL devices below.

NOTE: Halogen no longer supports the HAL1 and EXP1 devices. If you would like to create or update a

HAL1 configuration, use Halogen version 4.1.1 or earlier. To run multiple versions of Halogen on your PC,
see http://blog.rane.com/2013/01/15/tip-running-multiple-versions-of-halogen-on-one-computer/.

CHAPTER 2: Hardware Component Details

HAL1 (Replaced by HAL1x)

The HAL1 uses a daisy-chain FireWire expansion bus able to support up to four EXP1 devices with a total of 32
output channels and 64 input channels. The maximum cable length for FireWire is 14.8 feet (4.5 meters).

For more information about the HAL1 FireWire expansion bus and EXP1 expansion unit, see "Overview of HAL1
Expansion Unit (Discontinued)" on page 1.

The HAL1x expansion bus uses a proprietary protocol running on a gigabit Ethernet physical layer with expansion
devices connected in a daisy-chain configuration as before. The new expansion bus supports 512 output channels
and 512 input channels with a maximum cable length of 330 feet (100 meters). There are currently four expansion
devices for the HAL1x: EXP1x, EXP3x, EXP5x and EXP7x. The new bus is a significant improvement over the
original FireWire bus.

For more information about the HAL1x expansion bus and expansion units, see "HAL1x Expansion Units" on
page 64.

You cannot use the new (x) version expansion devices with the discontinued HAL1. The new HAL1x requires (x)
version expansion devices.

The device connections that are possible on a HAL1 are as follows:

l

4 Remote Audio Devices (RADs)

l

8 Digital Remotes (DRs)—Can add up to 4 more by plugging them into the RAD ports

l

1–4 Expansion Unit Devices (EXP1 devices) (FireWire Expansion Bus)

l

CHAPTER 2: Hardware Component Details

NOTE: In Halogen version 5.0.1 and later, you cannot create a new configuration for the unsupported HAL1

device.

Remote Audio Devices

The primary purpose of a Remote Audio Device (RAD) is to amplify, digitize, and transmit a digital audio signal
via shielded CAT 5e cable to a HAL host device. RADs can also receive a digital signal from the HAL and then
convert it to analog before sending it to its attached audio equipment. RADs are capable of transmitting and receiv­ing up to four channels of digital audio (two in each direction). To better fit your needs, however, Rane offers var­ious RAD models. Most RAD models are designed to fit in a standard U.S. two, three, or four gang switchbox.

The HAL System offers a variety of RAD models, each of which serves a unique purpose. For example, a RAD1
contains two microphone input channels. When you design an audio system, you choose the RAD models that are
appropriate for your application. You must then provide configuration information to HAL so that it knows which
RAD models to expect on each port and what information to send to each RAD. For more information, see "Avail­able RADModels" in the Halogen Help System. You can also read about the available RAD models on the Rane
website.

How the shielded CAT 5e Cabling is Utilized

The shielded CAT 5e cable that connects the RAD to HAL also provides power to the RAD as well as a path for
data communications. Data communications makes it possible to control the RAD’s configuration settings, view
status information, and update a RAD’s firmware – all from the host HAL device. The following picture illustrates
how the four twisted pairs within the shielded CAT 5e cable are utilized.

23

HAL SYSTEM INSTALL GUIDE

l

The orange pair is reserved for data communications between the RAD and HAL. Data communications is
needed for such things as sending configuration information from HAL to the RAD, sending firmware
updates from HAL to the RAD, and sending status information from the RAD to HAL.

NOTE: Configuration information for a specific RAD (for example, LED intensity, microphone sensitivity,

and RAD and channel names) is stored in the HAL device, not in the RAD. This makes it easy to swap in a
new RAD, if necessary, without losing configuration data.

l

The green and blue pairs carry two channels each of balanced, differential, digital audio. Tx refers to audio
that the RAD sends to the HAL. Rx refers to audio that the RAD receives from HAL.

l

The brown pair provides 24 VDC power and ground for the RAD. This is (obviously) the wire you should
check if it appears a RAD is not receiving power.

NOTE: Digital Remotes (discussed on page 43) use only the orange pair (for data communications) and the

brown pair (for power).

RADGrounding

Careful grounding of RADs is important for optimum performance. Except for the DR4, all RADs and DRs are
powered from the +24 VDC & Ground twisted pair located within the shielded CAT 5e (or better) cable con­necting them to the HAL system of multiprocessors. The exposed metal of all RADs and DRs is connected to the
ground conductor inside the cable and to the cable shield when properly terminated. The shield conductor and the
ground twist are in parallel and are connected together at both cable ends. Except for the RAD16z, this in turn con­nects the HAL/audio equipment rack grounding point and the metal (if used) junction box mounting the RADs
and DRs.

NOTE: For some electrical systems (e.g., isolated grounding systems - sometimes called a single point or star

ground) the grounding procedure outlined above may short two fingers of the building ground system. If this
creates a problem, then use of non-conductive junction boxes, or insulating mounting methods are rec­ommended (or very much required!).

NOTE: The RAD16z is grounded differently than the above. The RAD16z galvanicaly isolates its RJ-45 jack,

cable shield and grounded twist, and the HAL/equipment room ground from its logic and audio I/O grounds.
This means no special ground is needed. This provides 500-volts galvanic isolation as well as standard Eth-
