CrewCom Overview
CrewCom is a versatile yet straightforward communications solution built on an intelligent wireless and wired network-based
distributed system architecture. Innovative technologies have been specically developed to facilitate intercom system growth
and effortless adaptation, along with unparalleled digital wireless reliability for consistent operation, even in the most demanding
production environments.
Decentralized Network Architecture
The CrewCom system utilizes a proprietary network backbone, known as CrewNet™, to coordinate and transport all system timing,
audio, signaling, and controls. This efcient, decentralized resource network delivers increased exibility over that of traditional
technologies, using a distributed network-to-device intelligence within a modular building block structure. System components can
easily be placed where they are needed or scaled to facilitate system growth, reconguration, and effortless adaptation to changing
environments. For increased infrastructure exibility, the CrewNet network is capable of operating over standard Cat 5e (or greater)
and/or Single Mode Fiber (SMF) lines.
Flexible RF Platform
CrewCom’s RF platform is vast and exible to meet the needs of virtually any wireless communication challenge facing production
and entertainment professionals worldwide. Each CrewCom wireless product is available in the 2.4GHz and 900MHz (North
America, Australia, and New Zealand only) ISM bands and any combination of these frequency ranges may be simultaneously
used on the same CrewCom system. CrewCom makes it easy to operate in challenging RF environments by combining support for
multiple simultaneous frequency bands, while also allowing for simple system setup without the need for an RF engineer.

Introduction
In addition, a more robust RF link enhances RF range and reliability through a newly developed dual carrier double-send
transmission scheme that minimizes the adverse effects of inter-symbol interference. This innovation allows increased useful RF
range and improved performance, especially in large, reective environments.
Intuitive User Experience
CrewCom’s family of products is designed around a system architecture that offers a high density of users with a more manageable
infrastructure and lower cost per user than typically found in large-scale wireless installations. The CrewCom system not only
consists of a range of wired and wireless hardware products but also incorporates an intuitive software application, known as
CrewWare, working together with the system hardware to enhance the experience of system administrators, designers, integrators,
and users. Each device’s user interface allows a quick learning curve with high functionality, and its ease of use is consistent across
all frequency bands, types of users, and applications.
CrewCom Devices
The following is a list of available CrewCom devices. For more information on each of these products and their conguration
capabilities, visit our website at: www.plianttechnologies.com
• Control Unit (CU) – the 1RU foundational element of the CrewCom system that establishes the CrewNet-based
infrastructure while also providing external connections to common established intercom systems. Unlike traditional
BaseStations, the CU contains no radio and is frequency agnostic, which sets the groundwork for a multi-frequency
capable system. For maximum exibility, any CU can access, control, and monitor any active device across CrewNet. The
CU is available in a “CCU-22” or “CCU-44” model, which simultaneously support up to (2) 2-Wire and (2) 4-Wire or (4)
2-Wire and (4) 4-Wire intercom connections, respectively.
• Radio Transceiver (RT) – a CrewCom radio device that houses a radio (2.4GHz or 900MHz) and its corresponding
antennas, enabling RF communications to CrewCom Radio Packs. Using the CrewNet network as the system’s backbone,
RTs can be positioned throughout a wide coverage area by being linked back to a Control Unit either directly or through
a Hub(s). Connectivity is accomplished using either Cat 5e (or greater) or Single Mode Fiber (SMF).
• Radio Pack (RP) – the direct portable wireless communication device connecting individual CrewCom users to the
CrewCom system. Each RP provides full duplex audio communications and, through customized function buttons, General
Purpose Output (GPO) control and event logging. The RP requires a connected headset and access to a Radio Transceiver
on the CrewCom system. Devices are available in 2.4GHz and 900MHz bands as well as two and four volume/talk button
congurations.
• Copper Hub – a CrewNet-based device with eight ports to allow extended interconnection for a variety of CrewCom
hardware. Ports one through seven are copper (RJ-45, Cat 5e, or greater); port eight can be either an additional copper
port or a duplex LC Single Mode Fiber port, but only one may be used at a time. The Hub provides for extensive system
expansion and exibility.
• Fiber Hub – a CrewNet-based device with eight ports to allow extended interconnection for a variety of CrewCom
hardware. Ports two through eight are duplex LC Single Mode Fiber ports; port one can be either an additional ber port
or a copper port (RJ-45, Cat 5e, or greater), but only one may be used at a time. The Hub provides for extensive system
expansion and exibility.

Introduction

CrewCom Conguration File Overview
The CrewCom system operates using a CrewCom Conguration File (CCF) to coordinate the processes and data that make up the
system’s operation. A default CCF is available for your CrewCom system out of the box to provide your initial settings. You can use
CrewWare to customize your conguration to meet your specic needs beyond the default settings. The CCF stores the settings for
your Conferences and Proles, intercom settings, and connection information for your 2-Wire, 4-Wire, and CrewCom devices.
Conferences and Proles work together to create channels of communication between CrewCom users. They are dened for each
user, stored in the CCF, and available each time you set up. For more information about Conferences and Proles, continue reading
the following sections for their denition.
About Conferences
A CrewCom Conference is an administrator-dened grouping of audio entities (inputs such as Radio Packs, wired intercom ports,
etc.). Audio outputs are then created dynamically by mixing one or more audio entities and routing them to Conference subscribers
accordingly. This method of subscription-based audio using Conferences is very powerful. Point-to-point associations may also be
easily constructed using this method. Each association requires a separate, unique Conference. Conferences in CrewCom are full
duplex (i.e. bidirectional) and there can be a maximum of 1,024.
Default Conferences are included as part of a system’s default conguration. New Conferences can be created using CrewWare.
About Proles
Each CrewCom Radio Pack has a Prole that contains a variety of system settings that are dened as either system-level settings or
user-adjustable settings.
• System-Level – These settings are part of the system’s conguration and are usually assigned by a system administrator
through customization in CrewWare during setup. Find a full list of the system-level settings available for each Radio Pack
in the
CrewWare Operating Manual or the Radio Pack Operating Manual .
• User-Adjustable – A user-adjustable setting is one that is classied as being adjustable by the Radio Pack user and is
limited to local device settings that do not alter the CrewCom Conguration File. The Prole can be used to determine
these settings, but they can also be customized directly from a Radio Pack after a Prole is loaded.
About Network Power
Power-over-CrewNet (PoC) is a proprietary network protocol that carries operating voltage and current to CrewNet-compatible
devices connected to the Control Unit via RJ-45 connections (Cat-5e or greater.) Control Units must receive AC power via the
supplied power cord in order to operate and provide necessary PoC to connected CrewNet-compatible devices. In addition, PoC can
be supplied to devices downstream from a locally powered CrewCom Hub or RT.
For CrewNet-compatible devices using ber connectivity, local power must be supplied to that device using a Pliant 48VDC power
supply (sold separately).

Product Overview
Product Overview
The CrewCom Radio Transceiver (RT) serves as a point of contact for Radio Packs (RPs) on CrewNet. RTs are available in either
2.4GHz or 900MHz models, and they can be positioned throughout the coverage area to provide better, expanded coverage.
For a single Control Unit (CU) to allow the maximum 18 RPs to communicate wirelessly (6 per RT), a minimum of 3 RTs per single
CU is required. A single CU can support a maximum of 46 2.4GHz and 900MHz RTs; however, it will still only allow 18 RPs to be
active in this setup.
As stated above, a single CU can support up to 46 RTs. This count breaks down as follows:
• 32 2.4GHz RTs
• 14 900MHz RTs (in full band operation)
»In Oceania, a CU will support up to 32 2.4GHz RTs and up to 7 900Mhz RTs (in a reduced 900MHz band).
Note: Connected RTs may require supplemental Pliant 48VDC power supplies (sold separately) if there are too
many devices connected via CrewNet for the Power over CrewNet to adequately power all devices.

The RT’s CREWNET IN ports allow it to connect to any available CREWNET port on other devices or any RT LOOP port on other RTs,
thus adding the RT to a proprietary network where all devices are part of a conguration that shares data, timing synchronization,
and audio. Each RT has a CREWNET IN port (RJ-45 for copper or duplex LC for Single Mode Fiber) and an RT LOOP port (RJ-45,
which allows RTs to be daisy-chained (looped through) together). Each port’s status LEDs indicate the status of the CrewNet link.

RT Setup and Installation
RT Setup and Installation
Determining the Device Location
Follow these tips when determining a location for your RT and antennas:
• Every antenna has a certain pattern of coverage for which it is useful. The patterns of both CrewCom RT antennas need
to be focused in the same general area of the desired coverage area to ensure best RF results.
a. When possible, centrally position omni-directional antennas in the middle of the desired coverage area.
b. Don’t separate omni-directional antennas too far away from each other (not more than 3–4 m, 9–13 ft).
c. Don’t aim directional antennas in two different directions.
• Both antennas are necessary and equally important. Redundant transmissions from both antennas must regularly reach
the Radio Packs to have a robust, successful RF link.
• Higher is almost always better when placing antennas.
a. Maintaining a direct line of sight from the RT antennas to the Radio Pack is the best possible antenna scenario.
b. The minimum acceptable application of this is to get the RT antennas above head level. In many cases, the best
execution is to place the RT well above the desired coverage area and aim antennas directly down at the coverage
area.
Note: Always follow safety instructions. When the RT will be exposed to moisture, ensure proper
measures are taken to prevent water ingress.
• Always keep antennas away from the following:
a. Large metal objects. Stay at least two feet away from these.
b. Large containers of liquid. Most liquids are intense RF absorbers.
c. Conned spaces. Don’t set up antennas in rooms or areas with RF obstacles. Wide open spaces are good. Stay two
to four feet away from walls or ceilings.
Mounting the RT
1. Attach the supplied mounting plate to rear of RT using the provided screws and a #2 Phillips screwdriver.
2. Attach the provided 2dBi omni-directional antennas onto the RT’s antenna connections.
Note: Additional antenna options are available where legal. For more information, please contact an applications specialist.

RT Setup and Installation

Connecting to CrewNet
After securely placing the RT, connect it to the system via an available CREWNET port. RTs can be connected to any CrewCom
system via a Control Unit (CU), a Hub, or by daisy-chaining (looping through) from an existing RT. (An RT daisy chain can contain an
additional seven RTs after the initial one.)
For a single CU to allow the maximum 18 Normal mode Radio Packs (RPs) to communicate wirelessly (6 per RT), a minimum of 3
RTs per single CU is required. A single CU can support a maximum of 46 2.4GHz and 900MHz RTs; however, it will still only allow
18 Normal mode RPs to be active in this setup.
NOTE: In Oceania, a CU will support up to 32 2.4GHz RTs and up to 7 900Mhz RTs (in a reduced 900MHz band).
• RJ-45 Ports – For an RJ-45 copper CREWNET port, use the supplied 15 ft. (4.6 m) Cat 5e cable, or your own Cat 5e
(or greater) cable (up to 330 ft. (100 m) in length). Any CrewCom device connected to CrewNet via a Cat 5e (or greater)
cable will receive power-over-CrewNet (PoC) from the Control Unit via the CREWNET port. In some situations, there may
be too many connected devices or the cable lengths may be too long for the PoC to adequately power all devices, and
this will be indicated with the NET PWR LED lighting red. In this case, one or more supplemental Pliant 48VDC power
supplies must be used (PPS-48V sold separately).
• Fiber (Optical) Ports – For a ber CREWNET port, a Single Mode Fiber cable (duplex LC connector) will be required (up
to 32,800 ft. (10,000 m) in length). Any CrewCom device connected to CrewNet via ber port must receive power via a
Pliant 48VDC power supply PPS-48V (sold separately).
Powering the Device
After connecting your CrewCom devices, power everything on and verify that your RT is receiving power by checking that the
applicable Power LED is green.
After the Control Unit (CU) and the other CrewCom devices receive power and establish communication, the CU will ensure that
each device has the correct rmware version. If a device does not have compatible rmware, the CU will notify you. Disconnect the
device, connect it to your PC, and update device rmware using the procedures outlined in the
CrewWare Operating Manual .
Note: See the Connecting to CrewNet section above for more information on how power is distributed for all
connected CrewCom devices.
Activating the Device
If you are performing a new setup, and a CrewCom Conguration File (CCF) has not already been applied to your CrewCom system
at the Control Unit (CU), follow the Applying CrewCom Conguration File procedures in the CrewCom Control Unit Operating
Manual
to do so and activate your CrewCom devices.
If you are adding an RT to an existing CrewCom system after you’ve applied your CCF, the new device will not operate until it
is included in the current CCF and has a compatible rmware version with the CU. If these conditions are already met, the new
device will begin operating immediately. If not, you should follow the prompts on the CU’s display to activate the new device. (See
"Conguring One or More RTs" on page 10 of this manual.)
Note: If a physical device is missing, the CU LCD will alert you of the missing device(s). In this situation, you can
elect to physically connect the missing device or delete the missing device from the conguration le in CrewWare.
Advanced system conguration and customization can be done via CrewWare. Refer to the separate CrewWare Operating Manual
for more information on this process.

RT MANUAL

Operation
Operation
Conguring One or More RTs
Follow the prompts on the Control Unit (or CrewWare) to accept each new RT and add it to the current CrewCom Conguration
File. Then, you must also conrm each new RT’s radio band and hopping pattern before it will operate.
• Radio Band – All radios on a CrewCom system of the same frequency must be set to the same Radio Band. The default
Radio Band is selected automatically by choosing the widest Radio Band setting for that frequency range. The Radio
Band you use should follow the rules governing radio use in your country. You can change the system Radio Band
selection from the Control Unit or CrewWare, choosing either
Full, High , or Low.
• Hopping Pattern – The RT’s Hopping Pattern is selected automatically by comparing all the existing RTs and choosing
the next compatible number (within the same frequency range) available on CrewNet. You can either leave the Hopping
Pattern that the system selects or edit the Hopping Pattern to your preference. If you select a Hopping Pattern that is not
compatible with the Control Unit’s setting, a warning will display prompting you to conrm your preferred settings.
Pinging an RT
From the CrewWare Software or Control Unit (CU), an administrator can “ping” a Radio Transceiver, which triggers the device LEDs
to ash to identify and conrm its physical location.
To ping an RT from the CU, go to the CU’s Device Settings menu and select the RT you wish to ping. The LEDs will ash until the
ping is cancelled at the CU or using CrewWare, giving you or another person time to locate it. For more information on pinging an
RT, see the
CrewWare Manual .

Returning Equipment for Repair or Maintenance
All questions and/or requests for a Return Material Authorization Number should be directed to the Customer Service department
([e-mail]). Do not return any equipment directly to the factory without rst obtaining a Return
Material Authorization (RMA) Number. Obtaining a Return Material Authorization Number will ensure that your equipment is
handled promptly.
All shipments of Pliant products should be made via UPS, or the best available shipper, prepaid and insured. The equipment should
be shipped in the original packing carton; if that is not available, use any suitable container that is rigid and of adequate size to
surround the equipment with at least four inches of shock-absorbing material. All shipments should be sent to the following address
and must include a Return Material Authorization Number:

Cleaning
Generally, the CrewCom hardware should be cleaned only with a dry cloth. A soft cloth with rubbing alcohol may be used to wipe
the devices if needed, but you should avoid using rubbing alcohol on plastic components. Never spray solvents or chemicals onto
the devices.
All electronic devices can be susceptible to particulate contamination. If yours are exposed to an extremely dusty environment,
contact Pliant’s Customer Service for internal cleaning.
Temperature and Humidity
CrewCom components are designed to be very durable and can tolerate a wide range of environmental conditions; however, you
should take all necessary precautions to keep your system devices safe, dry, and out of extreme conditions.
The Radio Transceiver is weather-resistant, including gaskets intended to prevent moisture entry from the top and sides. The Cat 5e
cable connection on the bottom is not water tight. If it is to be used in an outdoor environment, protect the RT with a protective
enclosure that will not interfere with the RF.
The Radio Packs are designed to work wherever people work. While the Radio Pack design is weather-resistant, Radio Packs should
not be submerged in liquids unnecessarily. Protect the battery compartment from water when changing batteries. The battery
compartment offers a route to the electronic circuitry.
