Welcome

Thank you for purchasing the 6416i Input Module. This User Guide is designed to familiarize you with the features and functions of your new Pro64® product. All Pro64 products are powered by A‑Net®, Aviom’s proprietary data transmission protocol designed especially for the unique demands of live streaming audio. In developing the Pro64 Series, we have made every effort to make the user interface as easy to use and understand as possible. We encourage you to read the manual completely, as some of the powerful features of your new product may not be immediately apparent.

Features

The 6416i Input Module provides a host of professional features designed to make audio networking with Pro64 Series products easy to set up and configure in a variety of professional audio situations.
6416i Input Module Features:
Sixteen analog line‑level audio channels• XLR line‑level input jacks •
• DB25 Audio Thru/Alternate In connections Individual A‑Net• ® Slot activation buttons per channel Link switches for stereo channel pairing• Two A‑Net ports•
• EtherCon® RJ45 network connectors

The EtherCon Connector

Pro64 Series products feature locking connectors for all network I/O. The Neutrik® EtherCon connector is a dual RJ45‑type connector that can receive a standard Category 5e cable or a cable fitted with the special locking EtherCon connector.
When using a standard Cat‑5e cable, plug the cable into the center of the EtherCon jack; release the cable by pressing on the small plastic tab built into the cable connector.
The locking EtherCon connector is similar to an XLR plug, the kind commonly used on microphone cables. Insert an EtherCon‑equipped cable into the jack until it clicks and locks in place. To remove the cable, press on the metal release tab at the top of the panel‑mounted EtherCon jack and pull the connector outward.

Firmware Notice

All Pro64 devices in a network should be updated to use the most recent rmware version to ensure trouble-free operation.
As new Pro64 modules are released, older Pro64 products need to be updated so that they recognize the features and functions of the newer modules—something that is especially important if one of the older devices will be used as the network’s Control Master. (If for some reason you cannot update the firmware on older Pro64 devices before using them, set the newest module to be the network Control Master.)
Pro64 Update Tool is a free Windows software application for updating the operating firmware in Pro64 Series products.
The Pro64 Update Tool requires a direct RS‑232 (serial) connection between the computer and the Control Master device on the Pro64 network. Normally this is accomplished by connecting a null modem DB9 cable between the RS ‑232 jack on the computer and the Pro64 device. Complete information on using RS‑232 (and USB‑to‑RS‑232 adapters) is available on the Aviom website. Updates take just a few minutes per module.
Pro64 Update Tool is designed to run on a PC under Microsoft® Windows® XP. It has also been tested and found to be compatible with Microsoft Windows Vista®. Mac users can run Pro64 Update Tool using Windows XP running under Apple’s Boot Camp program on Intel‑based Macs.

About A-Net

Aviom’s A‑Net® is the only networking technology conceived, designed, and optimized for managing and distributing audio using ordinary Cat‑5e cables. As implemented in the Pro64® Series products, A‑Net can transmit up to 128 channels of uncompressed 24‑bit audio with the reliability and fidelity of analog, and the power and flexibility of a true digital network.
Pro64 A‑Net allows variable sample rates in three ranges, from 44.1kHz± to 192kHz±, with ultra‑low latency, jitter, and wander. Pro64 devices can be connected in any combination of serial (daisy‑chain) or parallel (star) topologies. Cable runs between Pro64 devices can be up to 400 feet (120 meters) on Cat‑5e1, and miles on single‑ or multi‑mode fiber optics (using Aviom fiber‑capable equipment such as the MH10f ).
Because A‑Net is designed specifically for audio, the technological limitations of Ethernet and Ethernet‑based products are removed, while audio performance and system flexibility are increased. A‑Net incorporates Aviom’s unique patented and patent‑pending algorithms for controlling clock jitter and wander, as well as system‑wide latency—regardless of an installation’s size, design, or clocking setup. A‑Net offers significant advantages in fidelity, performance, and flexibility over Ethernet‑based products.
A‑Net uses the “physical” layer of Ethernet, but it eliminates all the protocol elements that are designed for computers and IT‑style networking. In audio applications, these other layers reduce efficiency, impose system restrictions, and introduce latency and timing instability. By eliminating Ethernet data structures, A‑Net creates a superior network, with enhanced audio performance. With A‑Net and the Pro64 Series, Aviom continues to break new ground in the design and development of innovative digital audio networking technologies and solutions.
Pro64 Series Supported Sample Rates
Sample Rate Minimum Maximum
1x 44.1/48kHz 39.7kHz 52kHz
2x 88.2/96kHz 79.4kHz 104k Hz
4x 176.4/192kHz 158 .8 kH z 208kHz
Clocking
The Pro64 network offers the most flexible clocking and synchronization options in the industry. Pro64 devices support three ranges of variable sample rates, from 44.1/48kHz± to 192kHz±. Because no sample rate converters are
1 Cat-5e, Cat-6, or better, Unshielded Twisted Pair (UTP) cable
2Ab o u t A- Net
Page 13
used, audio transmission is kept fast and clean, eliminating the audio artifacts and signal degradation inherent to sample rate conversion—even when syncing to an external clock source.
Any Pro64 I/O module can be designated the clock master for the network, generating and distributing its internal clock. Digital I/O modules are capable of syncing to and distributing an external word clock.
Control Data
The Pro64 Series has built‑in, dedicated bandwidth for 14 channels of non‑ audio control data through the use of Aviom’s innovative Virtual Data Cables™ (VDC). These data streams are always available to carry MIDI, R S‑232/RS‑422, or GPIO (General Purpose I/O), and they never compete with the audio channels for network resources, regardless of the system configuration.
Because VDC inputs are simply incorporated into the A‑Net stream, these control signals can be transmitted over very long cable runs and even across an entire Pro64 network, significantly expanding the applications possible with MIDI, RS‑232/RS‑422, and GPIO. And as with audio signals, VDC control data can be input anywhere and output anywhere else in the network.
The exact complement of VDC I/O connectivity varies per product.
A-Net Ports
Pro64 I/O modules have dual A‑Net ports, labeled A and B. Both ports carry a bidirectional A‑Net stream at all times. (That is, both ports are always transmitting and receiving A‑Net data.) Pro64 networks can be configured in one of two operational modes, Auto Mode or Manual Mode, depending on the requirements of a particular application.
Each A-Net port carries bidirectional data at all times.
3Ab o u t A- Net
Page 14
In Auto Mode, there are no connection rules; connect a Cat‑5e cable to either the A or B port and the network does the rest. Auto Mode provides a true audio network with 64 available “Slots” for transporting audio (at 44.1/48kHz). Every audio Slot is available everywhere in the network, with no upstream/ downstream restrictions.
In Manual Mode, the Pro64 network becomes a 64x64 system (at 48kHz), similar to a traditional stage‑to‑FOH snake. At every point in the Manual Mode network, two 64‑channel streams are available on the cable and in each module. The configuration of the cables and ports has an impact on the makeup of the network and the distribution of audio signals. The user can direct A‑Net data from a Pro64 input module to a specific port (A, B, or both). Likewise, Pro64 output modules can be configured to output audio signals received from a specific Pro64 network port (A or B).
Support For Pro16 Series Products
Pro64 Series products can be combined with Pro16® Series output products such as the Pro16 Monitor Mixing System by adding the Pro64 ASI A‑Net Systems Interface. This 1U module converts Pro64 data to Pro16 data, providing up to four 16‑channel streams of data (depending on the Pro64 sample rate) that can be used with A‑16II and A‑16R Personal Mixers, A‑Net Distributors, and AN‑16/o Output Modules.
The ASI is not compatible with the A‑Net output of Pro16 input modules such as the AN‑16/i and AN‑16/i‑M and console interface cards such as the Y1.

AC Power

Always plug the unit into a properly grounded (earthed) outlet. Always use the AC line cord that was shipped with the unit. Grasp the power cable by the connector and never by the cord itself when connecting and disconnecting it from the power source.
Do not expose the Pro64 device to moisture, rain, or excessively damp environments.

AC Line Conditioning

Aviom products are digital devices and as such are sensitive to sudden spikes and drops in the AC line voltage. Changes in the line voltage from lightning, power outages, etc., can sometimes damage electronic equipment.
To minimize the chance of damage to your equipment from sudden changes in the AC line voltage, you may want to plug your equipment into a power source that has surge and spike protection. Power outlet strips are available with built‑in surge protection circuits that may help protect your equipment.
Other options for protection of your equipment include the use of an AC line conditioner or a battery backup system (sometimes referred to as an uninterruptible power supply, or UPS).

Rack Mounting

Pro64 products are designed to be mounted in a 19‑inch equipment rack. The rack ears on each side of the device are designed to support the weight of the product without additional hardware. Each rack ear contains holes for two screws per side. Always support the unit with all four screws to avoid damage to the unit.
To rack mount the Pro64 product, position it in the equipment rack at the desired location. Use standard rack‑mounting screws (10‑32 size) to attach the unit to your rack hardware. Tighten all four screws firmly, but avoid overtightening.
Aviom suggests the use of non‑metallic washers between the rack‑mounting screws and the device’s finished surface to avoid marring the finish on your Aviom products.

Ventilation

Always allow adequate ventilation for devices mounted in equipment racks. Avoid placing your Pro64 product directly above or below other rack‑ mounted devices that produce high levels of heat, such as power amplifiers.

Cleaning

Before cleaning a Pro64 product, turn off the power switch and unplug the unit from the AC power source.
To clean the surface of the Pro64 product use a clean, soft lint‑free cloth that has been slightly moistened with water only. For tougher dirt, use a cloth slightly dampened with water or with a mild detergent. Always be sure to dry the surface of the unit before proceeding with use.
When cleaning your Aviom products, never spray cleaners directly onto the product surfaces. Instead, spray a small amount of the cleaning solution onto a clean cloth first. Then use the dampened cloth to clean the product.
Never use solvents or abrasive cleaners on the finished surfaces of your Aviom products.

Pro64 Interface Conventions

Many Pro64 Series products have similar user interface components, including buttons, LEDs, and switches. When describing the features and functions of Pro64 Series products, the following conventions will be used.
Cat-5e
All Cat‑5e connections between A‑Net devices should use Unshielded Twisted Pair (UTP) cable. The cable can be of the stranded or solid type; solid wire performs better over long distances, while stranded wire is more flexible and easier to manipulate and therefore easier to work with in a performance situation.
Cables designated as Cat‑5e in Pro64 documentation can be interchanged with any Cat‑6 (or better) cable. Cables will be referred to simply as “Cat‑5e.”
Connectors on Cat‑5e cables can be of the standard RJ45 variety or locking Neutrik EtherCon type.
Button Presses
When referring to specific front‑panel labels, LEDs, and buttons or when describing a Pro64 function that requires the press of a button on the front panel of a device, a special typeface will be used. For example, “Press the En t E r button to confirm the sample rate change.”
Buttons that work in combination, giving the user a choice when performing an operation, will be referred to as one unit. For example, “Changing the sample rate requires the user to confirm the change using the Enter/Cancel buttons.“
Changing Values
When editing values on the front panel of a Pro64 device, some operations will require the use of the inc/dec (short for increment/decrement) buttons. These buttons scroll up and down through a list of available values. Holding the button down does not accelerate scrolling. The front panel of a Pro64 module is marked only with indicator arrows. (See the drawing on the following page.)
8Pr o 64 iN t e r F A c e co N v e N t i o N s
Page 18
The buttons with up/down indicator ar rows are used for the inc/dec functions.
Buttons of this type will be referred to as “inc/dec” buttons.
Selecting Values
Some settings, including Sample Rate, network mode (Auto or Manual), and Virtual Data Cable type, require the user to select from a range of values. The button that controls the selection of a value is referred to generically as the “selection button” for that function. For example, “Use the Sample Rate selection button to scroll through the available rates.”
Pressing a selection button repeatedly will scroll through the available settings and will wrap around when the end of the list is reached.
Pressing the s election button w ill cycle thro ugh the available values.
DIP Switches
Illustrations of Pro64 DIP switch components indicate the switch handles in black as seen below.

Pro64 User Interface

This section outlines some basic concepts of operation for Pro64 products. Pro64 I/O devices have some common user interface elements that make setting up a digital snake or audio network easy to understand.
Common elements include:
Enter button• Cancel button• A‑Net Slot selection•
• Network Mode (Auto/Manual) Sample Rate display• Managed button• Edit Lock button• Virtual Data Cable (VDC) configuration•
In addition, each I/O module has the ability to be set as the Control Master and/or Clock Master (depending on the actual makeup of the analog/digital modules in the audio network). Only one device can have control of these functions at a time in a properly configured Pro64 network.

Basic Actions

Most system‑level operations in the Pro64 user interface require the use of the Enter button to confirm an action. For example, assigning a Virtual Data Cable port to a VDC Slot or choosing a new sample rate (on the Clock Master device only) will require the user to press the En t E r button to confirm the request. If no press of the Enter button is detected within a predetermined time frame, the system will automatically cancel the request and return the device (or entire network) to the previous state.
Operations that do not require the use of the Enter/Cancel buttons include:
Stereo c• hannel link (input modules) Channel activation (input modules)• Channel • on/off (output modules) Gain settings (input modules)• Output • level settings (output modules)

The LED between the Enter and Cancel buttons ashe s when a button press is required to continue.
Any operation that requires the use of the Enter/Cancel buttons will flash the LED that is located between the two buttons to indicate that a button press is required to complete the action. To confirm an operation, press En t E r . To exit an operation without completing it, press the C a n C E l button.

A-Net Slot

Pro64 I/O devices come in a variety of configurations; to allow a large number of hardware audio input devices to be available to the Pro64 audio network, Aviom has implemented the concept of the A‑Net Slot to simplify the configuration of potentially complex audio networks.
A Pro64 audio network will always have a finite number of A‑Net Slots available that can be addressed by an unlimited number of hardware channels. The actual number of available Slots is determined by the current sample rate.
Slots versus Channels
You might be wondering why Aviom chose to refer to the audio I/O resources in the Pro64 Series products as ‘’Slots.” Why not just call them “channels”?
We did this to avoid confusion between references to hardware audio resources and network audio resources. The word ‘’channel’’ is ambiguous and may cause confusion when configuring an audio network. “Channel” appears in many contexts, including audio mixing consoles, mic preamps,
11Pr o 64 us e r iN t e r F A c e
Page 21
DSP processors, and DAW software.
We use the word ‘’channel’’ when referring to the physical audio inputs— analog or digital—on a piece of hardware (such as the 16 line‑level XLR input jacks on the 6416i Input Module). Each of these audio inputs can be made active and added to the network individually, and it is only when activated that they use any network resources (the A‑Net Slots). To allow this functionality, Pro64 products separate the hardware resources from the available network resources by giving each hardware input channel a button that allows it to be added to the network as needed.
It is these activated hardware resources that are being referred to as “Slots.” Pro64 audio networks can potentially have a greater number of audio channels and hardware I/O devices connected than the network can make use of at one time. This provides flexibility without requiring constant re‑ patching.
Keep in mind that a Pro64 A‑Net network can only manage a specific number of Slots at a time, and this number varies with the sample rate being used. The maximums are 64 Slots in Auto Mode at the 48kHz sampling rate and 64x64 Slots in Manual Mode at 48kHz.
In summary, think of “channels” as hardware resources that can be added to the network as needed and “Slots” as locations within the digital audio network pipeline that A‑Net uses to move data throughout the network.
Slots and Sample Rate
The current system‑wide sample rate will determine the number of A‑Net Slots that are available. Auto Mode and Manual Mode have the same number of Slots at each sample rate; only the direction of the data is different.
Sample Rate A-Net Slots
4 4.1kH z 64 48kHz 64
88.2kHz 32 96kHz 32
176.4kHz 16 192kH z 16
Even though the network sample rate may change the available number of A‑Net Slots, the capacity of a hardware device does not change. That is, a 16‑channel input module in a 192kHz network can still have all of its channels activated; all of its physical inputs can operate at 192kHz.
The current sample rate will also affect the display of available A‑Net Slot ranges. Slot ranges will always have the same maximum number as seen in the sample rate chart. At 96kHz, for example, only Slots numbered 1 through
12Pr o 6 4 use r iN t e r F A c e
Page 22
32 are available; the Slot range from 33 to 64 is inactive and unavailable at that sample rate. Slot ranges outside the maximum for the current sample rate can be selected, but attempting to activate a channel in an unavailable range will result in an error message (the selected channel button, A‑Net Slot range, and sample rate LEDs will all flash).

A-Net Slot Display

Since the capacity of the Pro64 network could be as high as 64 A‑Net Slots, Pro64 hardware I/O devices need a way of routing a selected hardware channel to a selected network Slot. In the upper left corner of the front panel of a Pro64 I/O device, the A‑Net Slot display and its associated inc/dec buttons are used to select a range of Slots that the hardware device will address.
The A-Net Slot display and its inc/dec buttons are use d to set the base Slot for a Pro64 I/O module.
The A‑Net Slot display will show the base number that is associated with the first hardware input or output channel on an I/O device. The actual number seen in this display will be determined by the physical I/O on the device. That is, an 8‑channel device will display a different set of available starting points than a 16‑channel device (see the following tables).
To select an A‑Net Slot range, use the inc/dec buttons below the display. Press one of the buttons until the desired base Slot range is displayed, and then press the En t E r button. To return to the current selection without making a change, press the Ca n C E l button.
The following tables show examples of the channel‑to‑Slot correlation for Pro64 Series modules in a network running at the 48kHz sample rate.

Network Modes

A Pro64 audio network can be set to operate in one of two modes, Auto or Manual. The network mode can be selected on the front panel of the device designated as the system’s Control Master.
Both modes are fully bidirectional at all times, regardless of the system layout or design.
Auto Mode
Pro64’s Auto Mode takes most of the work out of managing resources in an audio network. This is the “everything everywhere” mode. Channels are sent into the network and can be seen and used by all devices in the network, regardless of how the modules are connected and regardless of the physical location of any module. Output modules do not need to follow input modules as in a traditional analog system. In Auto Mode, both A‑Net ports (A and B) function identically.
Once configured for Auto Mode, the system ensures that only one hardware input channel is activated into a given A‑Net Slot. There is no limit to the number of hardware output channels that can use a given A‑Net Slot. The actual number of available Slots is determined by the current sample rate. The maximum number is 64 active channels at the 44.1/48kHz sample rate.
Sample Rate Available A-Net Slots in Auto Mode
44.1 / 48kHz 64
88.2 / 96kHz 32
176.4 / 192kHz 16
Manual Mode
When more than 64 channels are needed in a network, Manual Mode can be used to provide configurations of up to 64 x 64 channels. Two unique 64‑channel streams are available at each module. In Manual Mode, the A and B A‑Net port connections can be used to direct and route A‑Net data.
Pro64 input modules can send their audio inputs to either or both A‑Net ports, while output modules can listen to data from either port. For a traditional stage‑to‑FOH snake system, this allows the user to configure a system with up to 64 sends from the stage and another unique stream of up to 64 returns to the stage.
Manual Mode operation removes the restrictions of unique channel‑to‑Slot‑ range relationships found in Auto Mode. Slots can be overwritten, allowing the user to replace channels from one part of the network with new data.
17Pr o 6 4 use r iN t e r F A c e
Page 27
This means that, while no more than 128 channels can be in the network at a particular location, there is no practical limit to the total number of audio channels in the system.
The number of available Slots in Manual Mode is dependent upon the current sample rate.
Sample Rate Available A-Net Slots in Manual Mode

Control Master

In every Pro64 network, one device will always be designated as the Control Master, the device that manages all A‑Net resources for the network. The Control Master can be any I/O module in the network, and can be assigned or changed by the user as needed. Only one device can be assigned as Control Master in a Pro64 system at a time; an A‑Net network cannot function without a Control Master.
The functions of the Control Master include:
System resource and information management • Setting • network mode (Auto or Manual) Management of • active channels in Auto Mode System‑level command and control functions • Keeping track of all Pro64 devices in the network (by type •
and quantity) Control of the current system‑wide • sample rate
• Clock Master (analog modules only) System lock via • password on/off Management of • Virtual Data Cable (VDC) resources Management of • stereo link status Requests to enter Managed Mode •
The Control Master status is identified with a red LED on the front panel of the device currently assigned as the Control Master.
Only one device in a Pro64 network can be designated as the Control Master.
47co N t r o l mA s t e r
Page 29
Setting Control Master Status
Setting a device to be the Control Master is done using the DIP switches found on the rear panel. The Control Master switch is part of the Virtual Data Cable port section of the interface.
Switch 10 in the RS-232 conguration group is used to set the Control Master status for a module.
In the VDC section, locate the 10‑position DIP switch in the RS‑232 area of the rear panel. Switch #10 will set a module to be the Control Master for an audio network when the switch is in the On (up) position (the up position is shown in black in the diagram above).

Control Master Functions

This section describes the individual functions that the designated Control Master device in a Pro64 network controls.
Enumeration
When the Control Master is powered on, its first job is to identify and count all connected A‑Net modules in the network in a process called enumeration, similar to a PC booting up and loading its operating system. The time for this process will vary based upon the number of modules in a system.
Enumeration is an automated process performed by the command and control portion of the system. There are no user‑controllable functions or settings.
48co N t r o l mA s t e r
Page 30
During the enumeration process, all connected A‑Net modules will flash their A‑Net LEDs, indicating that a request to be added to the network is being made. Once granted entry by the Control Master, the individual module’s blue A‑Net LED will light solid to indicate that it is now receiving valid A‑Net packets and is part of the network.
The blue LED in the A- Net icon, shown here on a 6416i Input Module, is us ed to indicate network status.
If valid A‑Net packets are not received, the module will reset and wait until a valid A‑Net stream is detected.
During enumeration, any conflicts will also be resolved. For example, consider a new Auto Mode installation using eight input modules set to the same A‑Net Slot range with all channels activated during a bench configuration. When all these input modules are connected and then powered up, only one of them will be allowed to have all 16 channels activated. The remaining seven modules will have their audio channels deactivated.
Adding Pro64 Modules to a Network
When a new device is added to an existing network, the new device makes a request to the Control Master for inclusion in the network. During this time, the new module’s blue A‑Net LED will flash. When the new module has been enumerated by the Control Master, its blue A‑Net LED will then light solidly to indicate that the Control Master has granted the module access to the network. Adding a new module will interrupt network operation briefly.

Changing Settings

Most operations on Pro64 modules that make system‑wide changes require the use of the Enter and Cancel buttons. For any operation that requires confirmation, the LED between the Enter and Cancel buttons will flash to indicate that the user needs to press one of these buttons in order to continue.
Press En t E r to complete the operation or press Ca n C E l to exit without making a change. This rule applies to all functions that can be changed by only the Control Master.
49co N t r o l mA s t e r
Page 31
The Enter/Cancel LED will ash when the user is required to press one of these but tons in order to complete an operation.

Control Master and Clock Source

By default, the device designated as Control Master in a network consisting of all analog modules is also the device in control of the network master clock. The front‑panel Clock Master LED lights to indicate that a module is designated as the master clock device.
The red Clock Master LED lights when a Pro64 device is the Control Master.
When an analog I/O module is the Control Master, there is no other analog module that can be used as a clock source. When a digital I/O module is part of an audio network, the digital I/O device can be used as a clock master for the network, even if this digital device is not the network’s Control Master.

Clock Errors
If a clock error occurs, the Clock Master LED will blink indicating that an error has occurred. Common causes for a clock error include:

Attempting to change the clock source when the network • is password protected
Removing or changing external clock sources on a digital • I/O module
Incorrect configuration of an external clock source on a • digital I/O module

Network Sample Rate

When an analog device is the Control Master, the Control Master is automatically designated as the Clock Master. It will remain the Clock Master until a different analog module is made the Control Master or until a digital module is added to the network and requests to be the Clock Master.
The Clock Master LED will light automatically on the Control Master when that module is powered on. (Only a digital I/O module can be the source of the network’s master clock without being the Control Master.)
The system’s internal master clock is derived from the sample rate currently in use. The sample rate also affects the total number of available A‑Net Slots available for use in the network.
The Sample Rate section of an I/O module’s front‑panel interface includes a group of LED indicators for displaying the current network sample rate. One LED will be lit at all times.
51co N t r o l m As t e r
Page 33
Press the selection but ton to cycle through the available sample rates.
The current sample rate for the network will be displayed on all I/O modules in the network. Only one sample rate can be used at a time.
Changing the Sample Rate
To set or change a network‑wide sample rate from the Clock Master, use the button below the Sample Rate LEDs to select a new rate. Pressing the Sample Rate selector button will cycle through all available sample rates, flashing the value for the new rate. At the same time, the LED between the Enter and Cancel buttons will flash, indicating that pressing one of these buttons is required to confirm and complete (or cancel) the operation.
Changing the sample rate will affect the number of available A‑Net Slots when the sample rate changes from the 1x range (44.1/48kHz), to the 2x range (88.2/96kHz), to the 4x range (176.4/192kHz) or vice versa.

Auto/Manual Mode Selection

The Control Master can be used to set the current network mode for the system to Auto or Manual. As with the system‑wide sample rate, the network mode is also a global setting.
The network mode selection controls are in the same part of the user interface as the A‑Net Slot selection. The exact front panel text of an I/O module seen in this area will vary based on the type of module. For example, an input module front panel will read A‑Net Transmit, while an output module will read A‑Net Receive.
52co N t r o l mA s t e r
Page 34
The selec tion button in the A-Net Transmit/Receive section of the interface is used to choose the network mode on the Control Master. (Seen here is the 6416i.)
Changing the Network Mode
The button beneath the Auto/Manual Mode LEDs is used to select the network mode and to set the transmit or receive port in Manual Mode. Pressing the selection button will cycle through the available settings and will flash both the mode LED and the Enter/Cancel LED. To confirm and change the network mode, press the E n t E r button. The Control Master will update the display on all modules in the network to reflect the change. Press the Ca n C E l button to exit the mode change and return to the current state.

Managed Mode

Managed Mode requires the use of a computer with the Pro64 network for tasks such as firmware updates, system monitoring, control, and editing. The Control Master is the only module that can allow the network to enter Managed Mode.
Entering Managed Mode requires the user to press the En t E r button after pressing the Ma n a g E d button on the Control Master. Once the network enters Managed Mode, all modules will light their Managed LEDs.
53co N t r o l mA s t e r
Page 35
Managed Mode allows the networ k to be controlled from a computer and can only be entered from the Control Master.
To manage a Pro64 network with a PC, the PC needs to be connected to the Control Master using a DB9 null modem cable connected to the RS‑232 port.
Exiting Managed Mode is also done from the Control Master. Pressing the lit Ma n a g E d button followed by the En t E r button will return the network to local control. Attempting to enter or exit Managed Mode from any module other than the Control Master will cause the Managed button LED to blink to indicate the error.

Password Protection

All Pro64 devices ship with a default password. However, a Pro64 network can be password protected from the Control Master only. Once protected, the front‑panel interface on all modules is locked, preventing changes to A‑Net Slots, sample rate, clock source, channel activation, stereo links, and Virtual Data Cable assignments. Hardware switches, such as gain settings on input and output modules, and rear‑panel DIP switches are in the analog domain and are not affected.
Password protection remains in force even when a Pro64 system is power cycled.
When a network is password protected, the front panel interface can be used to get information on channel Slot assignments and VDC routings. Pressing a channel button will display its Slot assignment in the A‑Net Slot display. Pressing the VDC inc/dec buttons will cycle through the fourteen VDC Slots,
54co N t r o l mA s t e r

displaying any port assignments on the current module, as well as the In Use LED for all active VDC Slots in the network. This query behavior is similar to the behavior of an individual module when it is edit locked.

Front Panel Features

This section describes the features and functions of all front‑panel components of the 6416i Input Module.
Enter/Cancel Buttons

When a module is powered up, its A‑Net LED will flash while a request to enter the network is sent to and then processed by the device designated as Control Master. Once a module is enumerated and is part of the network, the blue A‑Net LED will light solid. The LED will remain lit as long as valid A‑Net network data is received.
The A-Net LED lights blue when the 6 416i is active on the network.
The A‑Net LED will flash during an operating system upgrade when the module being updated is part of an active network. When a module is being bench configured (it is not part of an active network), the A‑Net LED will be off during the firmware update. (Check the Aviom website for current firmware updates.)
Control Master
One Pro64 module in every network must be designated as the Control Master. To set the 6416i as the Control Master, one of the DIP switches on the rear panel in the VDC section is used. In the group of RS‑232 DIP switches, switch #10 is used to designate a module as the Control Master. Set this switch to the up position with the power off to avoid conflicts with network resources.
15Fr o N t PA N e l Fe A t u r e s
Page 43
When the Control Master module is powered up, the network will be enumerated and the blue A‑Net LEDs on all Pro64 devices will be lit. On the Control Master device, its red Control Master LED will also be lit. The Control Master LED will be off on all remote/slave modules in a network.
Control Master Errors
The following rules apply to the Control Master and active Pro64 networks.
If a slave module in an active network is incorrectly switched to be a Control Master (in addition to the network’s already functioning Control Master), that module’s Control Master LED will light and the A‑Net LED will go out to indicate the error. The Control Master LED will remain lit until the module is returned to slave status. All other module functions will operate normally.
If a new powered module set to be the Control Master is added to an active running network (one that already has a valid Control Master), the new module’s Control Master LED will light. Its audio I/O resources will remain unavailable until the module is returned to slave status. All audio on this module will be muted until the module is set to be a slave.
If the Control Master is removed from a functioning network (by being disconnected, power failure, etc.), all slave units will reset and audio will be muted. Slave units will wait for a new Control Master to be designated and at that point will begin the enumeration process.
A-Net Slot Configuration
The A‑Net Slot section of the interface is used to set the range of A‑Net Slots that the 6416i will use to send its active audio channels into the network. There are two components: the A‑Net Slot display and the inc/dec buttons used to select a value.
Press the up/down buttons to selec t an A-Net Slot range.
On a sixteen‑channel module like the 6416i, the A‑Net Slot display will move in increments of sixteen Slots. The A‑Net Slot range display will wrap as it reaches the end of the list of available values. The number shown in the display corresponds to the first Slot in a group of sixteen sequential Slots, one per channel button. The available base Slots are 1, 17, 33, and 49.

17 Slots 17‑32
33 Slots 33‑48
49 Slots 49‑64
Keep in mind that the number of available Slots is determined by the current network sample rate as set by the Clock Master.
Setting the A-Net Slot Range
To set a Slot range, use the inc/dec selection buttons found below the A‑Net Slot display to select the desired range. When the selection button is pressed, the new range displayed will start to blink, as will the Enter/Cancel button’s LED. This indicates that confirmation is required to complete the change. Press En t E r to set a new range or press Ca n C E l to exit without changing the A‑Net Slot range and return to the previous setting. If no press of the Enter/Cancel button is detected within a brief period of time, the interface will automatically cancel the range change request, returning to the previous state.
Setting a new Slot range on the 6416i will deactivate any currently active channels.
A-Net Transmit
The A‑Net Transmit section displays information about the current network mode, which can be set to Auto or Manual only at the network’s Control Master. When the Pro64 network is operating in Auto Mode, the red Auto LED will be lit, and no user settings are available on a per‑module basis. It does not matter which rear‑panel A‑Net port (A or B) is used when connecting devices to the network.
The Control Master can set the ne twork mode to Auto or Manual.
In Manual Mode, the user has the option of directing A‑Net data to either or
17Fr o N t PA N e l Fe At u r e s
Page 45
both A‑Net ports on the rear of the 6416i Input Module. Once the Control Master has set the network to operate in Manual Mode, the red Manual LED and at least one of the yellow Port LEDs will be lit on every Pro64 I/O module.
Three options are available:
Po r t a• ‑ the 6416i transmits data from its active channels only out of port A on the rear panel
Po r t • B ‑ the 6416i transmits data from active channels only out of port B
• Po r t a a n d B ‑ (both LEDs are lit) the 6416i transmits its active channels out of both the A and B ports.
A-Net data is set to transmit out of Port B in Manual Mode in this example.
Changing the A-Net Transmit Port
This applies to Manual Mode only; no user settings are available in Auto Mode. The VDCs are not affected by the network mode.
Use the selector button below the Auto/Manual Mode LED readout to cycle through the three options. When a new configuration is selected, the selected Port LED and the Enter/Cancel LED will blink; confirmation is required. Press En t E r to set a new transmit port or press Ca n C E l to exit without making a change and return to the previous setting.
Changing the port transmit settings in Manual Mode has no effect on the current channel activation settings.

Clock Master

One device in a Pro64 network will always be set as the network’s Clock Master. In a network with only analog I/O modules, the module set as the Control Master is also set to be the Clock Master by default. The Module set as the Clock Master will have its Clock Master LED lit.
When digital I/O modules are used in a network, incoming word clock or AES3 (also referred to as AES/EBU) digital data streams can also be clock sources. It
18Fr o N t PA N e l Fe A t u r e s
Page 46
is only when a digital module is part of the network that the Control Master and Clock Master can be separate devices.
Sample Rate
Pro64 networks can operate at sample rates in three ranges without the use of sample rate converters. The current network sample rate also determines the number of available A‑Net Slots.
Sample Rate A-Net Slots Available
44.1/48kHz 64
88.2/96kHz 32
176 .4 /19 2k Hz 16
In an all‑analog network, the sample rate can be set at the Control Master to the following:
4 4.1kH z• 48• kHz
88.2• kHz 96• kHz 176 .4• kHz 192• kHz
When an external clock is used with a Pro64 digital I/O device, the system can lock to any sample rate within the range sample rate that is displayed in the table below.
Pro64 Series Supported Sample Rates
Sample Rate Minimum Maximum
1x 44.1/48kHz 39.7kHz 52kHz
2x 88.2/96kHz 79.4k Hz 104 kHz
4x 17 6. 4/ 192 kH z 158 .8 kH z 208kHz
Changing the Sample Rate
The network sample rate can be changed only at the Clock Master. Changing the sample rate is done with the selection button found below the Sample Rate LED readout.
To choose a new sample rate, press the selection button beneath the sample rate list. Pressing the button selects the next sample rate in the list and immediately starts blinking the new rate’s LED and the Enter/Cancel LED;
19Fr o N t PA N e l Fe A t u r e s
Page 47
confirmation is required. To confirm the new sample rate, press the En t E r button. To exit without changing the sample rate, press Ca n C E l .
Pressing the s election button will cycle through the available sample rates.
Attempting to change the sample rate on a module that is not the Clock Master will cause the Sample Rate and Clock Master LEDs to flash to indicate the error.
Sample Rates and A-Net Slots
Changing the network sample rate has a direct effect on the availability of A‑Net Slots. For example, setting the sample rate to 96kHz makes only 32 Slots available, numbers 1 through 32. Slot numbers 33‑64 are no longer available.
If at the 48kHz sample rate an input module such as the 6416i is set to the Slot range starting at 33 or 49 and has active channels, these channels will be deactivated when the sample rate changes to 96kHz. These Slot assignments no longer exist in the network.
Channel Activation Button
Each of the sixteen line‑level input channels on the 6416i can be made active on the network individually using the lighted Active button found below the gain range switch on each channel. Activating a channel assigns it to an A‑Net Slot, making it part of the network and available to any output module in the network.
20Fr o N t PA N e l Fe A t u r e s
Page 48
Channel act ivation buttons are found below the Gain switches. Here, Channels 1, 3, and 4 have been made ac tive on the netwo rk.
In Auto Mode, each A‑Net Slot is unique. The Control Master manages the availability of A‑Net Slots and will grant or deny a channel activation request from an input module based on the current makeup of the network, the sample rate, and the Slots already in use.
To activate a 6416i input channel within a given A‑Net Slot range, press its numbered aC t i v E button. (Note that the word “Active” does not appear on the front panel user interface.) If the Slot is available, the Control Master will enable the Slot and the channel’s green LED will light. If the Slot is not available, the LED will flash briefly, indicating that the requested Slot is in use elsewhere in the network.
In Manual Mode, a channel can be activated at any time. Depending on how the network is set up and configured, activating a channel can replace a channel that was added to the network elsewhere.
Channel Activation Rules
It is not necessary to press the En t E r button to activate or deactivate a channel.
Each Pro64 module remembers a unique set of active channels for Auto and Manual Modes. For example, an input module could have channels 1‑8 active for an Auto Mode application and channels 5‑6 and 12‑16 active for a Manual Mode application. Changing network modes will restore the active channel status for each connected module.
Changing the A‑Net Slot range will clear the currently active channels on an input module automatically to protect against channel/Slot conflicts a or unintentional overwriting.
Level Meter LEDs
Each audio input channel on the 6416i Input Module has its own set of level LEDs—green, yellow, and red. Green indicates signal present; it turns on
21Fr o N t PA N e l Fe A t u r e s
Page 49
when a signal level of ‑40dB or higher is present. The yellow LED lights when the signal level reaches ‑10dB. Clipping is indicated with the red LED, which lights when the level reaches 0dB.
The level meter LEDs will always show the level of the incoming analog audio signal, even when the channel is not active on the network.
Always try to optimize the input level to assure proper gain staging throughout both the network and the connected audio devices.
Stereo Link Button
Adjacent pairs of channels on the 6416i can be linked together as a stereo pair. The channels must be an odd‑even pair, such as 1‑2, 7‑8, etc. There is one Link button for each channel pair, eight in all.
To link a pair of channels, both channels must be active on the network first; the Active button below the Gain switch must be lit on both channels. Once the two channels are active, pressing the li n k button will link the two channels immediately; no confirmation is required.
Attempting to link channels that do not meet the requirements above will cause the Link button and one or more channel button LEDs to flash to indicate the error.
To link a pair of channels, both channels must be active rst.
22Fr o N t PA N e l Fe A t u r e s
Page 50
Gain Switch
Each line‑level input channel on the 6416i has an individual four‑position gain switch that can be used to best match the incoming signal level. The default setting (no gain change) is 0dB.
The available gain settings are:
+6dB • 0dB • ‑6dB • ‑1• 4dB
Gain switches are in the analog domain and are not locked out from being changed when either the Edit Lock or Password protection features are used.
Managed Button
The Managed button is used to put the network under control of a computer for firmware updates, system monitoring, etc. Managed Mode can only be engaged from the network’s Control Master.
When using a PC for firmware updates, etc., a Pro64 module cannot have its RS‑232 or MIDI port assigned to a VDC when the PC is connected. Deactivate VDC assignments of this type before entering Managed Mode.
Managed Mode and Edit Lock buttons
To enter Managed Mode, press the Ma n a g E d button; its LED will flash. The Enter/Cancel LED will also flash. Press En t E r to confirm the mode change or Ca n C E l to return to the previous state.
To exit Managed Mode, press the Ma n a g E d button; its LED will flash and the
23Fr o N t PA N e l Fe A t u r e s
Page 51
Enter/Cancel LED will flash. Press En t E r to confirm the mode change. The network returns to the previous local mode, Auto or Manual.
In Managed Mode, Virtual Data Cable and channel Active buttons behave as if the module is edit locked; they provide information only when pressed. All other front panel edits are prohibited.
Edit Lock Button
The front panel of the 6416i can be locked to prevent accidental changes or low‑level unauthorized access. Once edit locked, all front‑panel functions under digital control cannot be changed. Analog functions, including channel gain settings can still be changed. Edit Lock can be used on a module‑by‑module basis.
To lock a module’s front panel, press the Ed i t lo C k button. The Enter/Cancel LED will blink. Press En t E r to lock the unit. No other Pro64 modules in the network are affected. Press the Ca n C E l button to exit the operation without locking the device’s front panel.
To unlock a Pro64 device, press the Ed i t lo C k button again. The Enter/Cancel LED will blink. Press the En t E r button to unlock the unit. Press Ca n C E l to exit, leaving the unit locked.
When a Pro64 module is edit locked, all front panel operations are inactive with the following exceptions:
The Edit Lock button, along with the Enter button,• can be used to unlock the unit.
• Gain switches on I/O modules are analog controls. These cannot be locked.
Channel • Active buttons can be used to get information about the channel‑to‑Slot relationships.
The • VDC inc/dec buttons can be used to get info on Virtual Data Cable port assignments.
Query Functions (Get Info)
When a module is edit locked, its front‑panel channel buttons can be used to get Slot info. Pressing any channel button will display the selected channel’s A‑Net Slot number in the A‑Net Slot display.
For example, if an input module is set to the A‑Net Slot range starting at 17, pressing channel button 2 will display “18,” channel button 3 will display “19,” etc.
24Fr o N t PA N e l Fe A t u r e s
Page 52
On an input module set to the A-Net Slot range starting at 17, pressing the Channel 2 but ton displays A-Net Slot 18 when the module is edit locked. Pressing the Channel 3 button will display “19,” pressing the Channel 4 button will display “20,” etc.
Channel activation status is not affected by the use of the query function. It is used for information only.
To exit the query function, press Ed i t lo C k followed by En t E r to return to normal operation.
Pro64 modules are set to provide query information whenever the network is in Managed Mode.

VDC Configuration

Pro64’s Virtual Data Cables provide an easy way to distribute control signals throughout a network, greatly expanding the possibilities for using and distributing MIDI, GPIO, and RS ‑232 control signals. A‑Net provides the ability to send these control data over greater distances than previously possible with traditional analog connections. And with MIDI and GPIO connections, infinite numbers of copies of the control data are available everywhere in the network.
Fourteen VDC Slots are available at all times; VDCs are not affected by the current sample rate or network mode. The makeup of the VDC Slots is user defined; no VDC Slots are reserved for specific data types.
The VDC interface includes the numeric VDC Slot display, the inc/dec buttons used for VDC Slot selection, the Assign Port list of VDC data types, and a selection button for choosing a VDC data type for the currently selected VDC Slot.

VDC Slot Display
The two‑digit VDC Slot display shows the currently selected VDC Slot (1 through 14). The In Use LED within the display indicates that a selected VDC Slot has an active input somewhere in the network. If only an output is assigned to a particular VDC, its In Use LED will not be lit.
When a rear-panel VDC port has been assigned to a VDC Slot, its In Use LED will be on.
Selecting a VDC Slot is done with the inc/dec buttons below the display. Pressing the inc/dec buttons will cause the display to scroll, and will wrap at the end of the numeric list.
26vdc co N F i g u r A t i o N
Page 54
As the VDC Slots are displayed, any VDC Slot with an active input will light the In Use LED. If the In Use LED is not lit for a selected VDC Slot, no input is assigned to that VDC Slot and all of the VDC type LEDs in the Assign Port list will be unlit when the VDC out has been assigned locally.
The available VDC data types for the 6416i are:
• R S‑232
• MIDI In
• MIDI Out
• GPIO In GPIO Out•
VDC In Use LED
The VDC In Use LED serves to indicate that a Virtual Data Cable Slot has a current active input assignment. Output assignments for MIDI Out or GPIO Out will not light the In Use LED.
The In Use LED will light whenever a valid assignment (GPIO In, MIDI In, or RS‑232) has been made anywhere in the network. The VDC Slot can only be used for the assigned data type until it has been deactivated at the point in the network where the input source has been assigned.
Assigning a VDC Slot
The act of assigning a VDC Slot maps one of the rear‑panel hardware VDC I/O ports to a Virtual Data Cable. To assign a VDC port to a VDC Slot, two actions are required. First an available VDC Slot must be selected, and second, one of the VDC data types from the Assign Port list must be assigned to that VDC Slot.
To select a VDC Slot to activate, scroll through the list to a numbered location that does not have the In Use LED lit.
To assign a data type, use the selector button below the Assign Port list to select the desired VDC data type, for example MIDI In. The LED next to the selected type will light; the Enter/Cancel LED will also start to flash. Press En t E r to enable the VDC Slot; press Ca n C E l to exit without assigning a VDC port.
To output VDC data from the network to a rear‑panel VDC port, choose a VDC Slot with an In Use LED on with the appropriate data type (for example, MIDI) for the application.
Once selected and configured, the rear‑panel I/O connection for the selected VDC can be used to transfer control signals.

Set a New Password
Each Pro64 module can store a network password. However, the password lock/unlock feature can only be used from the network Control Master. Passwords can be changed only when the network is unlocked.
The password is a four‑digit number created using the numbered channel activation buttons 1‑16 on the front panel. Passwords can include repeated numbers (such as the default factory‑supplied password of 1‑1‑1‑1). When creating a password, any string of numbers can be used, but note that only the last four button presses are stored.
To set a new password, press Fu n C t i o n and then the Ch a n n E l 10 aC t i v E button. Key in a four‑digit button combination and then press En t E r . The channel buttons flash to indicate that the new password has been set. Pressing the Ca n C E l button will exit the new password Function and leave the original password intact.
Sample Alignment
All digital networks that allow daisy‑chained connectivity need to compensate for sub‑millisecond latency build‑up between devices when data is retransmitted. In the majority of cases, there is no audible effect (as the individual delays are very small), but without compensation, these small variations in latency can become an issue in certain applications as the network grows in size.
On power up, each device in the network will calculate a sample alignment value based on the current sample rate and will apply it as long as the network is running. The next time the network sample rate is changed or the system is power cycled, a new value will be calculated and locked in. This sample alignment value will be referred to as the default value in the text that follows. Using the default value will offer the simplest method of operation.
However, to guarantee repeatable latency down to the microsecond, the user has the option of measuring the sample alignment amount for a given sample rate and then applying that calculated value every time the network is powered up. This is referred to as a stored value in the text that follows. By using these stored values, the Pro64’s unique software guarantees consistent delays between each component of the network.
Sample Alignment Lock Status
The sample alignment query, Function 11, can be performed on the Control Master or any remote unit in the network. The network can use the default value (created at the time of power‑up) or a stored value.

The red (Clip) LED indicates that the system’s default values • are being used. (This is set with Function 14.)
The green (Signal) LED indicates that stored values are • being used. (This is set with Function 13.)
Get New Sample Alignment Lock Value
To generate a new sample alignment lock value, use Function 12. This Function can only be performed at the Control Master when the network is unlocked.
Press the Fu n C t i o n button, followed by Ch a n n E l 12 aC t i v E button. The sixteen yellow channel meter LEDs and the Enter/Cancel LED will flash, indicating that this operation will replace the currently stored value. Press En t E r to generate a new sample alignment value, or press Ca n C E l to exit without updating the stored value.
Values are stored in each module’s memory but are not put into use until Function 13 (Use Stored Sample Alignment Values) is performed, which activates the stored sample alignment values. The module must be the network Control Master to use its stored value. Use Function 11 to get info on the current values in use.
When the stored sample alignment lock value is being used, a new sample alignment lock value should be calculated each time the network sample rate is changed, or when the system configuration changes. (Changes include the
32Ad v A N c e d Fu N c t i o N s
Page 60
addition/subtraction of Pro64 modules, different wiring schemes, etc.)
Use Stored Sample Alignment Lock Value
When a new sample alignment lock value has been generated and stored, Function 13 can be used to activate and lock in this value for use throughout the network. This Function can only be performed at the Control Master when the network is unlocked.
To use the stored value, press the Fu n C t i o n button, followed by the Ch a n n E l 13 a C t i v E button. The Enter/Cancel LED and the sixteen yellow channel meter LEDs will flash. Press En t E r to use the stored value, or press Ca n C E l to exit without changing the sample alignment value (the system reverts to using the default value).
The stored sample alignment value remains in force even when the network is power cycled. When the network is reconfigured or when the sample rate is changed, a new value should be calculated.
Use Default Sample Alignment Lock Value
The system calculates a sample alignment lock value to be used as the default every time the network is powered up, or when the sample rate is changed. Function 14 can be used at the Control Master to set the network to use the default value. (Function 13 is used to instruct the system to use a stored value. )
To set the network to use the default sample alignment value, press Fu n C t i o n , followed by the Ch a n n E l 14 a C t i v E button. The sixteen yellow channel meter LEDs and the Enter/Cancel LED will flash. Press En t E r to use the default value, or press Ca n C E l to exit without changing the current value.
Use Function 11 (Get Sample Alignment Info) to display the current value in use—default or stored.

Firmware Update

The Pro64 firmware can be updated in the field using a PC and the Pro64 Update Tool. Modules can be updated over A‑Net, while part of an active audio network, or in local mode where no other modules are connected at the time the update is being performed (such as may be required for a bench configuration when setting up modules prior to installation).
Updating a module requires the Aviom Pro64 Update Tool application, a PC host computer with RS‑232 connection capability, a null modem DB9 cable, and the firmware update file for the particular Pro64 device being updated. Refer to the Aviom website for information about the availability of the latest firmware upgrades and feature updates.
Update Connections
To update modules via A‑Net, a host computer is connected to the network’s Control Master via the RS‑232 port in the Virtual Data Cable section of the rear panel. Individual modules are then selected and updated from within the Pro64 Update Tool. Updates can be applied to the Control Master or a slave device.
To update via A‑Net, make sure that no RS‑232 or MIDI VDC resources are configured on the Control Master. (Refer to the Virtual Data Cable information page 33.) Then, enter Managed Mode by pressing the Ma n a g E d button on the Control Master.
To update modules locally, the computer is connected directly to the module being updated, via the RS‑232 port as described above. The Pro64 Update Tool application must also be set to its local update mode. (See the Pro64 Update Tool Help file for more information.)
Baud rates for data transfer must be set the same on the Pro64 device and PC host running the Pro64 Update Tool. Refer to the VDC RS‑232 baud rate info (page 60) to learn how to set the baud rate parameters. On the Pro64 module, RS‑232 must be configured for eight data bits, no parity, and one stop bit. Also, refer to the firmware update instructions that come with the Pro64 update application for additional information on setting up the PC host.

To enable firmware updates on the module, press Fu n C t i o n , followed by the Ch a n n E l 15 aC t i v E button. The Enter/Cancel LED and the sixteen red channel
level LEDs will flash to indicate that this function will interrupt normal network operation. Press En t E r to enable the module to receive new firmware from the PC host. Send the firmware update following the instructions that came with the Pro64 Update Tool. During the update the sixteen red, yellow, and green channel meter LEDs will flash in sequence.
When the firmware update has been sent successfully, the module will reset and normal front panel operation will be restored. If for some reason the firmware update fails, refer to the error recovery information below for instructions on how to recover and complete the update.
When a module is being updated locally, the dot in the VDC Slot display will be on, indicating that a local firmware update is in progress.
When a module is waiting for a firmware update to begin, you can exit the update state by pressing the Ca n C E l button. If the firmware update has not yet started, the module will attempt to reset, returning it to normal operation.
No t e : Do not press the Ca n C E l button while a firmware update is in
progress.
Error Recovery
In case of a partial firmware download or interruption to the firmware transfer (as would happen because of a power failure, computer crash, or by pressing the Cancel button in the middle of a firmware code update), the module can still be updated but will need to be powered up directly into the firmware load mode. To do this, hold the VDC Slot decrement (down arrow) button while powering up the unit. Then send the firmware from the computer as described previously.
If for some reason the firmware section is damaged on a unit being updated, it will default to receiving firmware update over A‑Net. This will allow you to continue the update procedure.
Firmware Update - via A-Net
To enable a Pro64 module to receive new firmware via A‑Net on an active network, the PC must be connected to the RS‑232 port on the Control Master. The network must be in Managed Mode to update firmware via A‑Net. All network audio will be muted, and front‑panel functions will be disabled on the module being updated.
To enable firmware updates, a module must be selected from within the Pro64 Update Tool application, at which point it will be setup to receive

new firmware. Send the firmware update following the instructions that came with the update firmware. During the update, the module’s sixteen red, yellow, and green channel meter LEDs will flash in sequence. When the update has been sent successfully, the module will reset and audio will be restored.
When a module is being updated via A‑Net in an active network, the dot in the A‑Net Slot display will be on, indicating that a network firmware update is in progress.
When a module is waiting for a firmware update to begin, you can exit the update state by pressing the Ca n C E l button. If the firmware update has not yet started, the module will attempt to reset, returning it to normal operation.
No t e : Do not press the Ca n C E l button or exit the Pro64 Update Tool
application while a firmware update is in progress.
Restore Factory Defaults
Function 16 restores the Pro64 module to its factory default settings.

Rear Panel Features

All 6416i rear‑panel features and functions are described in this section.
AC Power
Pro64 modules use switching power supplies that can operate at 100‑240V and from 50‑60Hz, meaning that they can be used with most of the world’s AC power systems by simply changing the line cord. The 6416i is equipped with a standard grounded IEC power inlet (with fuse), which can accept the interchangeable IEC power cord.
Fuse
The fuse holder is spring‑loaded and has space for two fuses, one main and one spare (optional). Press the fuse holder cover to access the fuse. When checking or replacing a fuse, always power off the Pro64 unit and remove the line cord from the AC power source.
Always replace the fuse with one with the same rating as that being changed.
A-Net Ports
Two EtherCon jacks are provided for A‑Net connections, labeled A and B. Connections can use standard RJ45‑style cables or cables outfitted with the locking EtherCon connector. Refer to the section on network modes for additional information about using these jacks.
Balanced Line-Level Inputs
The sixteen female XLR line‑level input jacks on the 6416i can accept +4dBu balanced or unbalanced audio signals. To use a mic‑level signal, a Pro64 mic‑ level module or a stand‑alone mic preamp is required.
6416i inputs accept balanced or unbalanced line-level signals.
29re A r PA N e l Fe A t u r e s
Page 66
DB25 Audio Thru/Alternate In
Two female DB25 multipin connectors are provided for audio throughput on the 6416i. Channels 1‑8 appear on one jack and channels 9‑16 on the other. The DB25s are wired to the industry accepted Tascam® compatible analog wiring standard.
Two DB25 multipin connec tors provide through connections.
The DB25 Audio Thru connection allows signals connected to the 6416i XLR input jacks to be connected to another input device such as a mixing console or Digital Audio Workstation (DAW) interface without interrupting the signals connected to the Pro64 network.
The DB25 connectors also function as an set of alternate line‑level audio inputs to the 6416i Input Module. Use DB25 cables wired to analog audio standards; never connect multipin cables wired for AES3 digital connection.
No t e : Do not use the XLR jacks and DB25 Alternate In connections for
inputs to the same set of channels on the 6416i simultaneously.
DB25 Pinout
Breakout cables for DB25‑to‑TRS, DB25‑to‑XLR connections, etc., are readily available. To create a custom cable for the Audio Thru/Alternate In function, use the following table and diagram.
DB25 Pin Number

The pins on the panel-mounted DB25 jacks are numbered according to the diagram above.
The DB25 panel‑mount connectors have #4‑40 UNC thread.
No t e : Strain relief is suggested when using DB25 cable assemblies. DB25
breakout cables should always be supported when connected to a Pro64 product to reduce the risk of damaging the Pro64 product’s rear panel.
Alternate Input
The DB25 Audio Thru connections can also be used as an optional main input path. Signals connected to the DB25 connections will be metered and can be made active on the network in the same manner as the XLR inputs.
Do not use the XLR jacks and DB25 Alternate In connections for inputs to the same set of channels on the 6416i simultaneously.

Virtual Data Cables

Three types of Virtual Data Cable (VDC) ports are available on the rear panel of the 6416i Input Module. Fourteen VDC Slots are available system‑wide, regardless of the current network mode (Auto or Manual). Virtual Data Cables are not affected by the network sample rate, channel activation settings, or gain settings.
When a module requests to activate a Virtual Data Cable, the Control Master checks the entire network to ensure that the requested VDC is available. Depending on the type of VDC requested, one or more VDC Slots must be available before the request can be granted.
When a VDC Slot has a valid input assignment, the Control Master broadcasts this information to the entire network. Each module in the network will display the In Use LED for any valid Virtual Data Cable input.
See the VDC info (page 33) for help configuring and using the fourteen available Virtual Data Cables.
GPIO
GPIO (General Purpose Input/Output) can be used to send contact closure or voltage‑type control signals through the network. Four input and four output blocks are provided. Each terminal block can be individually wired. GPIO inputs can be individually configured to be either Isolated or TTL.
GPIO Configuration DIP Switches
Each of the four GPIO Input blocks can be set to either Isolated or TTL operation using the configuration switches to the left of the terminal blocks.
The Isolated/ TTL conguration switches only apply to the GPIO inputs.
With the switch in the down position, the input is set to TTL. Use this setting for voltage‑type signals. GPIO inputs set for TTL operation can handle signal voltages up to 5 Volts.
The up position (Isolated) sets the input to accept on/off switch signals. Do not use the Isolated setting with voltage-based signals.
32vi r t u A l dA t A c Ab l e s
Page 69
See the GPIO Specifications later in this document for additional configuration information.
GPIO Terminal Blocks
Each GPIO input or output has a positive and negative contact that can be wired as needed. Four of each are provided. Only a small screwdriver is required.
MIDI In, MIDI Out
Two MIDI (Musical Instrument Digital Interface) ports, In and Out, are provided on the 6416i. Each is capable of transferring any type of MIDI‑compatible data. Pro64 devices do not process or filter MIDI data in any way.
Both MIDI por ts in the VDC section can be used simultaneously.
One MIDI In per Pro64 device can be assigned to a VDC Slot. An unlimited number of Pro64 modules can make use of the MIDI data by assigning MIDI Out to the VDC Slot with the same number as the input source.
Configuring a MIDI VDC
To assign a VDC to use the MIDI In port on the 6416i, first select an available VDC Slot using the inc/dec buttons below the VDC Slot readout. (VDC Slots with inputs that are currently in use will have the In Use dot lit.) Use the selector button to choose MIDI In from the Assign Port list. The MIDI In and Enter/Cancel LEDs will flash. Press the En t E r button to assign the port, or Ca n C E l to exit.
To output the MIDI data from the 6416i elsewhere in the network, select the same VDC Slot on the remote Pro64 device. Set the remote device’s VDC type in the Assign Port list to be MIDI Out. Repeat this step on any other Pro64 module that needs to output the same MIDI data.

Page 70
VDC Slot 14 on the 6416i is set to receive MIDI In from the rear-panel jack.
A remote Pro6 4 device set to output MIDI data.
RS-232 Port
The Pro64 RS‑232 VDC ports allow a pair of devices to transfer control data at rates up to 57.6k baud across the Pro64 network. Using Virtual Data Cables for RS‑232 always requires two VDCs because RS‑232 data transfers requires communicating devices to be set up in a handshaking pair. Note that RS‑232 communication is point‑to‑point, meaning that a maximum of seven RS‑232 sessions (14 total devices) is possible when using Pro64 Virtual Data Cables.
The rst eight switches on the DIP switch block are used to set the R S-232 baud rate.
The RS‑232 port is also used for computer communication for software updates and other Managed Mode applications.
The RS‑232 port on the 6416i uses a 9‑pin DB9 connector and eight of the ten DIP switches in the DIP switch block (the remainder are used for system functions).
34vi r t u A l dA t A cA b l e s
Page 71
RS-232 Configuration DIP Switches
RS‑232 communication is configured using the first eight switches in the DIP switch block. Switches 1‑4 set the baud rate and switches 5‑9 are used to set data, parity, and stop bit options. Switches 9 and 10 are reserved for system use.
Switch Function Off On
1 Baud Rate bit 3
2 Baud Rate bit 2
3 Baud Rate bit 1
4 Baud Rate bit 0
5 Data Bits 7 8
6 Parity Low/High No parity Parity
7 Parity Even/Odd Even Odd
8 Stop Bit 1 2
9 Reserved
10 Control Master
To set a DIP switch to the On position, push it upwards.
See Baud Rate chart
RS-232 Baud Rates
To set a baud rate, determine the appropriate baud rate for data transfer by referring to the external send/receive devices’ documentation. Set both devices to communicate using the same baud rate. Finally, set the Pro64 devices to the same baud rate and activate the VDCs using the front‑panel interface.
Here, the 6416i is set for a 57,600 baud RS -232 transfer with 8 data bits, no parity, and stop bit set to 2. (Black indicates the DIP switch handle.)

Control Master DIP Switch
In the RS‑232 DIP switch block on the 6416i, switch #10 is used to set the module as the network’s Control Master. Only one module can be designated as Control Master in a Pro64 network.
When switch #10 is in the up position, the 6416i becomes the network ’s Control Master. (Black indicates the DIP switch handle.)
To set the 6416i as the Control Master, start with Pro64 network devices powered off. Set switch #10 to the up position. Power up the 6416i and the rest of the network devices. The red Control Master LED on the front panel of the 6416i should be lit indicating that it is now the network’s Control Master.
No t e : Be sure that only one Pro64 device is set to be the network Control
Master.

Building a Pro64 Network

Configuring a Pro64 network with the 6416i involves connecting input and output modules with Cat‑5e cables, setting A‑Net Slot ranges, and activating input channels.
Choosing a Network Mode
When designing a digital snake or network, deciding which network mode to use—Auto or Manual—can be made simpler by assessing the total audio channel requirements for an application at a given sample rate first.
If you want to build a 48kHz system, for example, that requires no more than 64 total audio channels, choose Auto Mode; this is the easiest to implement. The network takes care of most of the management tasks automatically.
If the system is larger than 64 channels at 48kHz—for example, a 56x16 digital snake for a live performance stage to front‑of‑house application—choose Manual Mode. Pro64’s Manual Mode offers the most flexibility but requires more care when connecting modules and configuring input routing.
Connecting Pro64 Modules
Start by setting one (and only one) device to be the network’s Control Master. Because there are some operations that can only be executed at the Control Master, be sure that the module designated as the Control Master is accessible. Once all modules in the network are enumerated (indicated by illuminated A‑Net LEDs), choose a network mode (Auto/Manual), set A‑Net Slot ranges on each module, and activate audio channels and VDCs as needed.
When adding input modules to an existing audio network running in Manual Mode, it is best to add modules that are not pre‑configured with active channels and/or VDC Slots in use to avoid unwanted overwriting of A‑Net Slots. Pro64 output modules’ audio channel on/off settings do not cause conflicts with the allocation of audio input resources but existing VDC settings on these modules can impact the network. It’s best to clear old settings before adding modules to a system.
Basic Routing
To make use of the audio inputs connected to the 6416i, the module must be connected to another Pro64 device somewhere in the network that can output its digital data. This Pro64 device can be a standalone analog or digital module or a console interface card.

Auto Mode Connections

In Auto Mode, the 6416i’s A‑Net ports on the rear panel can be connected in any combination to other Pro64 devices. In the following examples, network performance and functionality are unaffected by the changes in cabling.
Example 1: Port A connected to Port B
The Cat-5 A-Net cable can be connec ted to either Port A or Port B. Reversing the A-Net connections causes the same results. Either port can be used to expand the network.
Up to 16 analog audio inputs can be activated on the 6416i Input Module. Pro64 devices can be connected to the 6416i using either Port A or Port B; the same active channels will be available at the output module.
Remember that the entire 64‑channel A‑Net stream (at 48kHz) is always received and transmitted through every Pro64 module. The A‑Net Slot selection simply tunes a module in to a specific range of channels.

The same results can be achieved by connecting Port A on the input module to Port A on the output module and by connecting Port B on the input module to Port B on the output module.
Digital Copies in Auto Mode
Any number of digital copies (also referred to as digital splits) can be created by simply connecting additional Pro64 output devices and setting them to the same A‑Net Slot range as the source. In Auto Mode, the order and location of the modules in the network does not matter; output modules can be connected before or after any input module. Optionally, Pro64 modules can be connected in parallel via a Pro64 merger hub such as the MH10 .
Any Pro64 input and output modules that are set to the same A‑Net Slot range can input or output data, making the configuration of large networks straightforward.

In this example, note that the A-Net connections between devices c an use any combination of the A and B ports. Any open port c an be used to connect additional Pr o64 devices to expand the system.
The order of the Pro64 modules connected in series in Example 3 above can be changed without affecting the ability of the network to distribute the same incoming audio channels to all three output modules shown. A‑Net ports always transmit and receive the entire network (audio and VDC data) at all times.
The rules are the same when larger networks are created. Simply set different A‑Net base Slots on the I/O modules to use more A‑Net Slots as needed. Cables can be connected to any available A‑Net port, A or B. Remember that in Auto Mode that the maximum number of active input channels at 48kHz will be 64.
Adding a Merger Hub in Auto Mode
For more wiring options, an A‑Net Merger Hub such as the MH10 or MH10f can be added to a network. Using a merger hub enables parallel connection of A‑Net devices. Multiple merger hubs can be used to simplify rack wiring and the distribution of digital signals amongst the various subsections of a digital audio network.
No t e : Standard Ethernet networking products are not compatible with
Pro64 products. Use only Pro64 A‑Net compatible devices.

MH10 in Auto Mode
In Auto Mode, modules can be connec ted to any port on the MH10.
Note that in the example, it does not matter which A‑Net port (A or B) on the I/O modules is connected to the MH10. Likewise, on the MH10, the choice of A‑Net port (1 through 10) does not matter. Any audio channel inputs made active on the 6416i in the diagram will be available to all output modules.

Manual Mode Connections

When creating bidirectional networks that require more than 64 channels (at 48kHz), Manual Mode is the answer. Unlike Auto Mode, Manual Mode requires that the user pay attention to which A‑Net port (A or B) is used when connecting network cables to each module. As implemented in the Pro64 Series of products, A‑Net is a truly bidirectional stream of up to 64x64 channels at all times.
In the examples that follow, the diagrams will indicate the specific A‑Net port on an I/O module that is in use with a square as shown below. Input modules such as the 6416i can send active audio channels to Port A, Port B, or both Ports A and B.
Port A is being used to send active audio inputs into the network, indicated by the square sur rounding the “A” Port.

The input module transmits it s audio data via Port A (marked with a square surrounding the port name). Only the lower Pro64 output module can make use of those audio channels.
In the example above, showing three modules in the middle of a network, the input module in the center of the diagram is set to transmit its active audio data to Port A, using the A‑Net Slot range starting at 1. The output module below it is set to listen to any A‑Net data that arrives on its Port B. The output module at the top of the diagram is set to listen to data arriving at its Port A.
Since the input module is directing its data to Port A, only the bottom module can output the audio channels made active on the input module. Again, the example assumes that all modules are set to the same A‑Net Slot range. Remember that all network audio is always transmitted and received at each A‑Net port. The module’s Slot Range selection simply tunes into a specific range of channels.

In this example, two input modules are set to the same A‑Net Slot range (01). Both modules are set to transmit their A‑Net data out of Port A. Unique data flows in each direction in a 16x16 configuration. Each output module will receive data from only one of the input modules in the configuration.
The next example refines this drawing by adding specific locations for the modules in a traditional stage‑to‑FOH snake system.

Audio from the input module seen at the bottom of the diagram (at FOH) travels up through all the modules in the network; its audio is available at the output module at the top of the diagram.
Audio from the input module on the stage travels through the network to the FOH position where it is output to the mixing console by the Pro64 output module there.

Creating a digital split in Manual Mode follows most of the rules defined for Auto Mode splits. Any output modules connected in series to an existing output module can output the same audio as long as the A‑Net Slot range and A‑Net Receive Port settings are configured properly, and as long as no input modules installed overwrite the audio. However, the location of the Pro64 output modules used for the splits will impact the front‑panel transmit port settings of the input modules.
Example 8: Adding a digital split of the FOH signals

FRONT OF HOUSE
RECORDING
The input module at FOH transmit s its audio data out of both A-Net ports, providing a digital split.
17bu i ld i N g A Pr o 64 Ne t w o r k
Page 82
In the previous example of a stage and front‑of‑house system, adding a digital copy of the FOH engineer’s inputs for a recording system can be accomplished by connecting Pro64 output modules to the input module at front‑of‑house. Unlike Auto Mode, however, this input module needs to be set to send audio data to its A‑Net Port B in order to make the digital split work.
The example assumes that all modules are set to the same A‑Net Slot range. By setting the FOH input module to transmit its A‑Net data to Port A and B, the A‑Net data flows in two directions. Digital audio arriving at the front‑of‑ house location from the stage is replaced by the input module at FOH.
To send the stage audio to the recording system instead, set the input module at front‑of‑house to transmit its data out Port A only. By doing this, the audio from the stage flows through all the modules to the recording system.
