In an analog wireless transmission system, the transmitted audio signal is at risk of being intercepted by a receiver of an outside system. When using FM modulation, audio signals can be received by anyone with the right equipment and some technical knowledge. By contrast, the digital audio wireless transmission system transmits encrypted audio data, which mitigates the risk of such interception and provides highly secure transmission for even the most critical applications.

Technology WiDIF-HP Technology Outline A digital audio wireless transmission system handles audio after the analog signal has been converted into digital form by an A/D converter. er and 15.4 the ut res s of a ter, iver. In conventional analog wireless systems, the compander providing compression and expansion is a key component for enabling wide dynamic range. The compander system uses complex analog circuitry for maintaining sound quality and response characteristics. However, this analog system requires advanced techniques to keep performance levels constant, because analog circuits are subject to the performance instability and adjustment tolerances of parts. By contrast, the digital audio wireless transmission system is free from such instabilities as it does not require a compander system. In short, digital audio wireless transmission is an optimum system to transmit high-quality audio signals without deterioration. Transmitter The transmitter in the digital audio wireless transmission system digitizes analog audio signal inputs from microphones and mixers and then wirelessly transmits them as a digital signal. This section describes the processes that occur within the transmitter. e ers, ardless meters An analog audio signal is first amplified in the amplifier and digitized in the A/D converter. The codec then applies data reduction techniques to the digital signal from the A/D converter and transcodes it into a digital bit stream with a lower bit rate. In the channel coding section, sync data and error processing data required for wireless transmission are added to the audio data, and the resulting data are encrypted. The digital modulator generates the π/4 QPSK modulation signal used to transmit the channel coded digital stream over the digital wireless link. The modulated signal is supplied to the RF block which amplifies the modulated carrier to the power level required for transmission. Microphone Full digital processing Amp. A/D 24 bit CODEC 48 kHz Digital Modulator Channel Coder RF Block Mixer Digital modulation Receiver Upon receiving the modulated carrier wave from the transmitter, the receiver reproduces the digital audio signal and outputs it as either an analog or digital signal to audio equipment such as an audio mixer or a power amplifier. This section describes the processes that occur within the receiver. In the RF block, the received signal is digitized by the A/D converter. Similar to the transmitter, three main processes are then performed in the signal processing block: digital demodulation, channel decoding, and codec processing. After receiving the signal from the RF block, the digital demodulator reproduces the digital stream that was channel coded at the transmitter. Then the channel decoder performs synchronization, decryption, error processing, and audio data extraction. The codec expands the signal that was data reduced to a low bit rate in the transmitter and reconstitutes the digital audio signal. The reconstituted digital audio signal is routed through the D/A converter and amplifier to be output as an analog audio signal or as a digital signal corresponding to standard audio interface specifications such as AES/EBU.

RF Block Digital Demodulator Channel Decoder CODEC 24 bit D/A 48 kHz AES/EBU Camcorder WiDIF-HP Technology 7 Technology Sony’s Proprietary WiDIF-HP Codec Digit In the wireless system, audio signals have to be transmitted within a limited wireless bandwidth. Transmitting the highest possible quality audio in this limited bandwidth is the major issue for wireless microphone development. In addition, low-latency audio transmission is another requirement of microphone applications. To transmit the best quality audio within limited bandwidth, Sony developed a digital wireless transmission system that employs a proprietary WiDIF-HP codec, which realizes both outstanding sound quality and low latency.

Outstanding sound quality with 24-bit/48-kHz sampling Low latency Secure transmission The Sony digital audio codec achieves an optimum balance between sound quality, bit rate, and latency, while having the redundant bit assignment necessary for wireless transmission. Channel Coding and Decoding In order to ensure high quality audio signal transmission within the given bit rate limits, WiDIF-HP employs synchronization technology to keep the error count as low as possible, along with error processing technology that minimizes the risk of noise when an error occurs. These techniques were developed and optimized using extensive simulation and field testing programs covering all wireless system operation aspects such as RF signal attenuation, Doppler effect, RF reflections, and more. Signal encryption is also handled at the coding stage.

In addition to benefiting from advanced RF technology know-how in the field of analog wireless transmission systems, the digital audio wireless transmission system also incorporates a digital modulation system that is less vulnerable to wave interference. These technologies allow highly stable wireless transmission even for a large number of simultaneous multi-channel operations. The newly developed Sony digital modulator and demodulator enables up to 12 channels of simultaneous multi-channel operation in a bandwidth of just 6 MHz. Using a unique algorithm optimized for wireless microphone applications, the digital modulator and demodulator are small enough to be integrated into an FPGA for portable devices. cy, Digital modulator on the one-chip IC DATA Modulated signal Filter I Filter Q Mapping QPSK modulation Digital modulator on the one-chip IC nology using F ding RF I Demodulator Q Detector DATA RF AF WiDIF-HP Technology 9 Technology Key Features of WiDIF-HP This section describes the advantages of WiDIF-HP technology. Stab High-Quality Sound Transmission on a Par With Wired Microphones High sound quality is the most important aspect for a wireless transmission. This is achieved through wide dynamic range, flat frequency response, and excellent transient response performance, factors that are essential for high-performance broadcasting and PA systems. Analog systems make use of companders to provide the required dynamic range. However, while compander systems have improved over time, their inherent problems with regard to sound quality and transient response performance have not been completely solved. WiDIF-HP technology was developed by Sony to fundamentally improve the transient response performance and therefore further enhance sound quality. It employs 24-bit/48-kHz sampling and provides: Wide dynamic range of more than 106 dB Wide frequency response of 20 Hz to 22 kHz Superb transient response performance Dynamic Response Response [dB] Frequency Response Frequency [kHz] Analog Wireless System Digital Wireless System (WiDIF-HP) Low latency audio transmission The second key aspect of the WiDIF-HP codec is low latency. In a digital device, signal delays can often occur due to the sampling, synchronization and calculation process. In particular, when wireless microphones are used for vocals or speech applications, keeping this delay short is crucial. In a commonly used codec such as the MPEG AAC, more than 20 milliseconds are required just for decoding. The high processing speed of WiDIF-HP provides a fundamental solution to this problem and further enhances sound quality by realizing a total delay of only 3.4 milliseconds* over the entire path from A/D converter in the transmitter to D/A converter in the receiver. High-speed response approaching linear systems Low latency of only 3.4 milliseconds* in send/receive path Low latency Total latency (A/D to D/A): 3.4 msec.* Converted to spatial distance: 1.2 m Note When digital mixers or similar equipment are used along with the digital wireless system, their latency values will be added. It is therefore necessary to consider the overall latency of the system. * This is the combined latency of the Digital Wireless Microphone DWM-01, Digital Wireless Transmitter DWT-B01, and Digital Wireless Receiver DWR-R01D. When analog output is combined with the Digital Wireless Receiver DWR-S01D, the latency rating is 3.6 milliseconds. 10 Key Features of WiDIF-HP Stable Wireless Operation Highly Resistant to Interference pander ponse nce Analog system The D/U (Desired/Undesired) signal ratio will be the S/N ratio of the demodulated audio signal. Because interference will be reproduced as noise, the higher the undesired signal level, the higher the noise will be in the modulated signal. Typically, analog systems require a D/U signal ratio of 40 dB or more. Digital wireless system Provided that there are no errors, the audio signal quality will not be degraded. In the Sony digital wireless system, an error does not occur provided the D/U signal ratio is 20 dB or more. Therefore sound quality will not be impaired as long as this condition is met. Digital modulation FM modulation CH 1 CH 1 Desired Analog system usually needs D/U > 40 dB Undesired System P) Spectrum D/U > 20 dB Error Free CH 2 CH 3 CH 4 Desired Undesired Spectrum * D/U ratio: Desired/Undesired ratio occur s are oding. ances in the The Sony DWX series of digital wireless microphones employing the WiDIF-HP format provides interference rejection that surpasses conventional analog systems by 20 dB or more (more than 10 times better in terms of reception voltage level), resulting in improved operation stability. he cy re ess Key Features of WiDIF-HP 11 Technology e e Compared to conventional analog systems, the DWX series employing the WiDIF-HP format provides significantly better rejection of noise, third-order intermodulation, same-frequency interference and other forms of interference. The improvement is on the order of 20 dB or more (more than 10 times better in terms of reception voltage level). This results in improved operation stability. Technology Simultaneous Multi-Channel Operation Com With WiDIF-HP, the number of transmitters that can be used within the same band frequency is 1.5 times that of an analog system, allowing for greater operability. RF and third-order intermodulation The RF related circuit design is an important aspect for realizing multi-channel operation. In wireless systems with multiple channels, the intermodulation that is generated in the RF amplifier of the transmitter/receiver often causes interference between the wireless channels. The RF block of an analog wireless system must be designed carefully to deal with intermodulation. However, intermodulation cannot be eliminated completely, either in an analog or digital system, as long as the RF part is composed of analog circuits. RF spectrum CH 1 CH 2 Third-order intermodulation signals will occur at 639.500 MHz and 641.000 MHz CH1: 640.000 MHz CH2: 640.500 MHz Frequency CH 1 CH 2 CH 3 Third-order intermodulation signals Wireless channel cannot be allocated due to the intermodulation noise CH 1 & 3 CH 2 & 3 CH 1 & 2 CH 1 & 2 Frequency Why are digital wireless systems advantageous to simultaneous multi-channel operation? In an analog system, the D/U (Desired/Undesired) signal ratio will be the S/N ratio of the demodulated audio signal. The higher the undesired signal level, the higher the noise will be in the modulated signal. Typically, analog systems require a D/U signal ratio of 40 dB or more. In the Sony digital wireless system on the other hand, an error does not occur provided the D/U signal ratio is 20 dB or more. Therefore sound quality will not be impaired as long as this condition is met. The digital wireless system provides interference rejection that surpasses conventional analog systems by 20 dB or more, and is therefore much less prone to problems caused by intermodulation and is more efficient in handling frequencies within a limited frequency range.

By contrast, a digital system allows the use of encryption to make the wireless transmission secure. The signals cannot be decoded by a conventional wideband receiver. This makes it easy to maintain confidentiality for conference rooms, live performance venues and other applications where strong measures against interception are required. The Sony digital system offers the choice between a secure mode using encryption keys, and a password mode where a secure group comprising multiple transmitters and receivers can be created. Metad Secure key mode This is a one-on-one arrangement where the encryption key generated by the transmitter is used for a single transmitter/receiver pair only. The mode provides highly secure strong encryption. Password mode A password that can be freely specified is set for a number of transmitters and receivers, and only equipment using that password can communicate with each other. Connection to equipment without the password set is blocked, resulting in secure operation. Application example: broadcast station All pieces of equipment used by the station are assigned the same password, allowing secure operation by staff without having to worry about complicated setup procedures or information leaks. It is also possible to broadcast audio from one transmitter to multiple receivers. Besides applications in the broadcasting sector, this kind of system is also suitable for example for government and other public offices where information must be transmitted securely. Analog wireless system FM-modulated audio signal Digital wireless system (WiDIF-HP) Digitally modulated coded audio The risk of being intercepted by a receiver of an outside system. For confidential communication, WiDIF-HP provides two communication modes: 1) Secure key mode 2) Password mode Notes Encrypted transmission does not guarantee 100% confidentiality. Changing the password on a regular basis is recommended. Using 14 Key Features of WiDIF-HP Metadata Transmission rd Technology Along with the audio signal, comprehensive information about the transmitter is sent as metadata, including audio input level, battery status, attenuator setting, etc. This enhances operation convenience, since the transmitter status can be monitored in any of the following ways: On the display of the receiver In the viewfinder of the camcorder (when using a slot-mounted camcorder; receiver information can also be monitored) In Wireless Studio (a dedicated software application supplied with the Digital Wireless Receiver DWR-R01D) ight make Metadata transmission principle Receiver uses data to display detailed status information Send comprehensive information about transmitter a single Receiver Transmitter RF signals ut the Metadata n by e to ctor, n must Normal information display Audio level meter Transmitter status display example Transmission power indication QL meter Audio input level meter Wireless remote control condition indication Display switching Transmission battery indication RF level meter Model name Input level Attenuator level Transmission battery indication Example for transmitted information (with DWT-B01) Transmitter name Battery status RF power setting Attenuator level setting Low-cut filter setting Continuous operation time Using metadata Metadata can be used for setup of other connected equipment.

Soun For details, see “UHF System Configuration” (page 38). RFI (Radio Frequency Interference) Noise WiDIF-HP performs cyclic packet transmissions similarly to mobile phones, computers, and other digital transmission equipment. The nonlinear devices (FETs, etc.) in the condenser microphone pick up these other RF signals, and RFI noise may occur according to the packet format as a result. Countermeasures are therefore required. This applies in particular to DWX transmitters set to high output (50 mW). The RF signals emitted by WiDIF-HP may affect the lavalier microphone. RFI noise may also occur due to RF signals emitted by mobile phones, computers, and other digital equipment. Lavalier microphone Mobile phone signals At pro sam cu Detection 2.4G Wifi Noise countermeasures Use cables with effective shielding. Take measures to implement RF immunity of microphone unit. Use lavalier microphones designed to be used together with digital wireless equipment that include RFI noise countermeasures. Notes Dynamic microphones are typically not subject to exhibiting this type of RFI noise. Sony professional lavalier and shotgun microphones with a suffix /9X in the model name, such as the ECM-77BC/9X, are certified by Sony to be suitable for use with the DWX digital wireless system. Other Sony professional microphones without a /9X in the model name may not be suitable for use with the DWX system. Microphones from Sanken, DPA, or Countryman include models that do not produce RFI noise and can therefore be used with the DWX system. For details on compatible models, contact the manufacturer of each microphone. 16 WiDIF-HP Precautions Sound Quality Degradation under Weak Field Conditions — Analog and Digital Propagation At the same power, the propagation reach is the same, but behavior in the cut-off region is different. Sound quality bile When compared at an equal transmitter power level, the following differences will occur as correlated to the reception level. There will be an area where 1) digital wireless retains high sound quality, 2) analog wireless suffers from deteriorated audio S/N ratio. There will be an area where 1) digital wireless starts to exhibit intermittent muting, 2) analog wireless has lower S/N ratio but sound remains audible. Digital Analog Noise noise plies in This graph shows a conceptual rendering. It does not represent actual measurement values. Audio dropout Field strength Distance The differences in sound quality degradation under weak field conditions may be experienced as a subjective difference in service area size. With WiDIF-HP, error processing has been optimized for a digital wireless system where intermittent muting increases as the signal gets weaker. Operation patterns should be decided based on application requirements and an evaluation of characteristics at the service area limit. FI noise Because WiDIF-HP is tuned to maintain voice clarity as much as possible even when errors occur, evaluation of error rates within the service area should be done using the Quality Level (QL) meter on the display of the receiver or of the Wireless Studio application. The QL meter allows observation of transmission quality changes over time. ony an of WiDIF-HP Precautions 17 Technology Provided that the transmitter power is the same, the signal level at the receiver at a given distance will be the same for a digital wireless and analog wireless system. This means that both systems can be said to have a service area of the same size. However, as explained in the preceding sections, the audio quality degradation behavior when field strength becomes low is significantly different for digital wireless and analog wireless. Technology Mixed Digital/Analog Systems Syste When digital wireless and analog wireless systems are used together, take the following points into consideration. Channel plan limitations In a mixed digital/analog wireless system, channel plans designed for analog systems must be used. Equal channel spacing applies only to fully digital wireless systems. Equal channel spacing is not available for analog wireless systems. Notes Refer to Sony digital wireless system frequency lists for further details on pre-programmed groups of frequencies built into every DWX transmitter and receiver. Sony’s built-in pre-programmed frequency groups provide 500 kHz channel spacing for digital channel plans D1-D9 along with analog channel plans 01-09 (containing irregular channel spacing) to ensure compatibility with Sony analog wireless system channel plans. Analo Digita Analo Common frequency interference precaution When operating adjacent to an analog wireless system, the minimum distance for analog wireless systems must be observed. 180m 30m Digital wireless system operation area (radius 60 meters) Digita 300m Analog wireless system operation area (radius 60 meters) 180m 180m Digital wireless system only 18 WiDIF-HP Precautions Analog wireless system, or mixed analog/ digital system System Behavior in Case of Interference To understand how analog and digital systems can have a mutual effect on each other in actual operation, it is important to consider the way in which the demodulated audio signal deteriorates when interference occurs. Technology Analog Analog lable The stronger the interference, the higher the level of unwanted signals mixed to the audio. This is heard as so-called beat noise, a chirping or squealing sound. Digital Analog As interference gets stronger, a “digital type” hiss noise will gradually be mixed to the audio of the desired signal. There is no beat noise typical of analog to analog interference. If the receiver has a function for detecting noise and muting the output, the audio will eventually be cut off as the interference noise increases. nel re Analog Digital Behavior is the same as for digital to digital interference. As interference gets stronger, errors will cause intermittent audio degradation. When interference increases further, intermittent muting will occur more frequently. Finally, the output will be completely muted. ms Digital Digital eration Behavior is the same as for analog to digital interference. As interference gets stronger, errors will cause intermittent audio degradation. When interference increases further, intermittent muting will occur more frequently. Finally, the output will be completely muted. With WiDIF-HP, sound quality will not be impaired as long as the D/U signal ratio is 20 dB or more. Unlike with analog systems, there will also be no loud beat noise in case of interference. The rapid transition characteristics from high sound quality to muting when interference increases are the same as for weak field reception. If the same channel must be used in adjacent areas, suitable measures should be taken to ensure a D/U signal ratio of at least 20 dB. Such measures include maintaining minimum distances, making appropriate settings for transmission power, and appropriate antenna installation design and settings. The RF indicator and QL meter functions of the receiver should be used to determine the final channel plan and equipment settings. WiDIF-HP Precautions 19 Technology Cross Remote Technology Cross Remote is a system that allows transmitters to be monitored and controlled from a receiver and the Wireless Why Studio control software installed on a computer connected to the receiver. Cross Remote Outline Compared to analog wireless systems, the DWX series allows more channels to be operated simultaneously. The Cross Remote system for remote control of transmitters from a receiver was developed to facilitate setup and operation of large wireless microphone configurations. Cross Remote uses an independent 2.4 GHz RF carrier (compliant with the IEEE 802.15.4 standard) to implement remote control that is separate from the UHF main link. This allows simultaneous audio transmission and remote control operation without affecting the battery life, audio quality and other features of the wireless microphone system. Attenuator and low-cut filter settings as well as power, frequency and almost all other transmitter settings can be controlled remotely. Even when the transmitter is worn concealed on the body, Cross Remote makes it easy to change settings remotely. How Cross Remote works Cross Remote transmits the data described below, allowing remote monitoring and operation of the transmitter from the receiver side. DWM-01 Metadata transmitted via WiDIF-HP Status information for each transmitter is sent on Monitoring and control possible at receiver Covers transmitters currently being received ST mode uses the internal 2.4 GHz antenna respective UHF frequency If metadata monitor function only is used, service 2.4 G area is equal to UHF (sound) range AN-01 UHF DWR-R01D BNC Cable 2.4 GHz Control data sent via 2.4 GHz NT mode RMU-01 IEEE80 * Used in NT mode only. RMU-01 transmits control information for all transmitters on network (max. 82 units) Up to nine RMU-01 units can be used, to enlarge service area *Internal 2.4 GHz antenna of receiver cannot be used ST mode Control information is sent to currently received transmitters (max. 2) via internal 2.4 GHz antenna Cross Remote protocol is expanded over Ethernet network Protocol is TCP/IP based 100Base-TX/10Base-T network equipment can be used RMU-01 used for 2.4 GHz antenna expansion Both modes DWT-B01 Transmitter identifies received control data by ID Network HUB Control results are returned as WiDIF-HP metadata LAN Cable Area where UHF and 2.4 GHz communication overlaps is service area for control functions Monitoring and control with Wireless Studio 2.4 GHz communication range has a radius of about 10 meters in a space with good line of sight In sleep mode, WiDIF-HP is not received. Two-way 2.4 GHz communication is used for monitoring Allows integrated system management PC * When using the DWR-S01D as receiver, the RMU-01 or a computer cannot be used. 20 Cross Remote Technology Up to 6 Windows PCs are supported s Why does Cross Remote use both UHF and 2.4 GHz frequencies? Technology Cross Remote is a two-way communication system for transmitters and receivers that uses both UHF and 2.4 GHz frequencies to complement each technology’s strengths and advantages. Advantages of 2.4 GHz (over using two-way UHF) usly. etup mission wireless her dy, Two-way UHF would require a built-in receiver on the transmitter and would result in higher power consumption, larger equipment size, and higher cost, making the implementation of this approach impractical. Because two-way UHF uses UHF channels for control, the number of channels that can be used simultaneously is reduced. 2.4 GHz control on the other hand does not effect the number of channels that can be used simultaneously. Advantages of UHF (over using two-way 2.4 GHz) nsmitter iver UHF communication is always on. If an audio link is established, it will always reach the other party. 2.4 GHz on the other hand is not always on, in order to save power. 2.4 GHz uses common frequencies on a time sharing basis and connects only when needed. The control signal (upstream) sends the same information to 82 units simultaneously, and status information (downstream) can be divided into separate UHF streams. In NT mode, up to 82 transmitters can be monitored and controlled together using RMU-01 units and Wireless Studio. With 2.4 GHz, communicating with all 82 transmitters would take time. When using UHF and 2.4 GHz, the combination of 2.4 GHz for upstream and UHF for downstream links results in a communication system that realizes a smooth workflow. 2.4 GHz IEEE 802.15.4 Technology Cross Remote uses 2.4 GHz band IEEE 802.15.4 communication technology that does not affect the band used for digital wireless audio communication. IEEE802.15.4 standard er n IEEE 802.15.4 is a worldwide standard for close-range communication applications using the 2.4 GHz band. Bands within the 2.4 GHz range are called ISM* bands and are widely used for microwave ovens, WiFi and Bluetooth applications, as well as for data transmission in medical institutions and similar. * Abbreviation of “Industrial, Scientific and Medical”. Frequency range allocated to wireless communication in these fields, requiring no license to operate. N Cable Notes IEEE 802 is a set of network standards developed by the 802 committee of the IEEE (Institute of Electrical and Electronics Engineers). It comprises the following standards: 802.11 Wireless LANs 802.15 Wireless Personal Area Networks (WPANs) 802.15.1 Bluetooth 802.15.3 UWB 802.15.4 Wireless Sensor Network (PAN standard with low power consumption and low transfer rate) Reference: About ZigBee This is a short-range wireless communication standard for domestic appliances. It uses the physical layer interface defined by the IEEE 802.15.4 and newly defines the network layer, security service provider, and application layer. ZigBee is not identical with IEEE 802.15.4. th ported Cross Remote Technology 21 Technology System configuration Used Application Layer: APL Layer Defines the protocols for user interaction on the network (pairing and address allocation). Cross Remote defines APL layer. Determines the network configuration and pairing method, roaming principles, and protocols. ST mode/NT mode switching is also performed here. (Note: ZigBee also defines these specifications.) Media Access Layer: MAC Layer Defines the specifications for device interaction on the network (error correction, ACK, resend request etc.). Physical Layer: PHY Layer Cross The MAC layer and PHY layer are defined by IEEE 802.15.4. Defines the wireless principles for the network (frequency, modulation principle etc.) Follows RF standards for various countries. Why was IEEE802.15.4 adopted? Among alternatives such as 2.4 GHz wireless LAN, Bluetooth, and UWB, Cross Remote has chosen IEEE 802.15.4 for the following reasons. Very low power consumption avoids degradation of battery life for the main communication link. Very fast wakeup from sleep state. Intermittent operation further contributes to power savings, while posing no inconvenience for users. Communication speed and range are suitable for control requirements. In addition to point-to-point communications, network can be expanded, allowing control of multiple transmitters from multiple computers. Cross Remote uses the physical layer and MAC layer specified by IEEE 802.15.4, and defines the application layer according to the requirements of convenient on-site use. Notes Why RF wireless rather than infrared? Whereas infrared wireless becomes unusable when there are screens or other obstacles, RF wireless allows remote control of a transmitter even when worn under clothing. Why 2.4 GHz band? Among the frequencies covered by IEEE 802.15.4, namely 868 MHz, 915 MHz, and 2.4 GHz, the 2.4 GHz band was chosen because it allows worldwide use. It is suitable as a common platform for devices to be used globally. 22 Cross Remote Technology Used frequencies pairing Cross Remote frequency bands IEEE 802.15.4 comprises the following specifications, but because of RF regulations, only the 2.4 GHz band can be used worldwide. 868 MHz (BPSK, 20 kbps) 915 MHz (BPSK, 40 kbps) 2.4 GHz (O-QPSK, 250 kbps) 02.15.4 Cross Remote uses the 2.4 GHz band to allow identical specifications for all global regions. The 2.4 GHz band comprises 16 channels spaced at 5 MHz, from 2.405 GHz (channel 11) to 2.480 GHz (channel 26). Out of these, Cross Remote uses the following frequencies. ST mode: 2.405 GHz (11ch), 2.425 GHz (15ch), 2.450 GHz (20ch), 2.475 GHz (25ch) NT mode: 2.420 GHz (14ch), 2.445 GHz (19ch), 2.470 GHz (24ch) osing Wireless LAN and channel allocation Channels 1, 6, and 11 are commonly used for wireless LANs. 2.400 GHz – 2.4835 GHz tion Ch.5 Ch.10 Ch.4 Ch.9 Ch.3 ws Ch.8 Ch.2 Ch.7 Ch.1 and 2 MHz 11 Ch.12 Ch.6 Ch.11 22 MHz 5 MHz 12 Ch.13 13 Wireless LAN 25 MHz 14 NT 15 ST 16 17 18 19 NT 20 ST 21 22 23 24 NT 25 ST 26 IEEE802.15.4 Conditions for frequency switching Channels are switched when the following conditions occur: A wireless LAN starts to operate on the currently selected channel and remote control communication is no longer possible. Interference is detected at the receiver. The network is reconfigured. A reset is performed, and the system starts scanning for an empty channel. When a channel is found, the system waits for transmitter reconnection. When the connection is interrupted, the transmitter scans all channels and looks for a reconnection target. When the paired equipment is found on another channel, the reconnection process is initiated. Note Channel switching does not necessarily occur for all types of interference. Short, sporadic interference cannot be avoided by this technique . Channel switching is effective for prolonged interference caused by streaming or similar operations on the wireless LAN. The receiver controls whether channel switching is performed. Even if subject to interference, the transmitter does not initiate channel switching. Cross Remote Technology 23 Technology med here. ons.) Cross Remote selects the optimal frequency for communication based on the system and the environment. If interference is detected on a currently used frequency, the system automatically switches to another frequency and continues communication. This assures stable operation even under congested 2.4 GHz conditions. Technology Pairing Roam Prior to being able to use the Cross Remote control functions, the transmitter and receiver must be assigned to each other in a process called pairing. The relationship between transmitter and receiver is that of Coordinator to Device. When NT mode is used, the Remote Control Unit RMU-01 is the Coordinator. Pairing requirement Because Cross Remote uses only three frequencies to control multiple transmitters (up to 82 in NT mode), it is not possible to identify devices by frequency assignment, as for the main communication link. As the control signal reaches all transmitters within the service area, pairing is necessary to establish which receiver is operating which transmitter. Roam Control of transmitter A is intended, but signals also reach unrelated transmitter B. Only commands from paired receiver A are processed. Receiver A Transmitter A Signals are received from receiver A but are addressed only to transmitter A, and are therefore not processed on transmitter B. Receiver B Signals are also received from unrelated receiver B. Transmitter B Transmission content for pairing Establish Coordinator/Device allocation Exchange ID information The MAC address is used as ID. In NT mode, the Ethernet IP address is also registered in the transmitter. Exchanging abbreviated ID information for communication Sending basic transmitter information (transmitter receiver) The following information is sent. dB range available for attenuation Phantom power supply present/absent, etc. Setting the frequency (transmitter receiver) Notes If pairing was established in ST mode, renewed pairing is necessary when NT mode is to be used subsequently (because the Ethernet IP address information is not registered in ST mode). The receiver can display up to 8 candidates for pairing. As the ninth and subsequent transmitters will not be displayed, do not set too many transmitters to pairing mode at the same time. 24 Cross Remote Technology Roam Roaming ), e eiver is Technology In NT mode, when the connection between transmitter and remote control unit is interrupted, the transmitter automatically searches for another remote control unit to connect to. If found, the transmitter connects to that remote control unit, and the connection to the paired receiver is established again. This process is called roaming. The Cross Remote service area can be enlarged by using multiple remote control units and maintaining communication through roaming. ned to dinator Roaming in NT mode RMU-01 NG Receiver Transmitter RMU-01 t are e B. Transmitter When communication with connected RMU-01 is interrupted... ...the transmitter scans all channels looking for a RMU-01. (The RMU-01 connected immediately prior is assigned a lower priority. When other RMU-01 units are found, the transmitter connects to them in the order they are found.) When a RMU-01 is found, a connection request is sent. Same sequence as during startup is performed. Notes Roaming is only carried out if current communication is interrupted. The number of antenna bars displayed in the “Cross Remote” control condition indication, indicates the communication quality, and not the field strength. Interruption can be caused by insufficient number of antennas, even if RMU-01 is in close proximity. During roaming, connection requests are issued in the order that RMU-01 units are found. The connection is not necessarily established with the closest RMU-01 unit. The RMU-01 unit with which communication was interrupted immediately before will have a lower priority for reconnecting. The scan is carried out for not only for NT mode but also for ST mode. When there is a mix of ST mode and NT mode systems or when there are multiple NT mode systems, the roaming process will take longer. Roaming times will not When one transmitter performs roaming in a normal communication environment The number of operation channels does not significantly change the roaming time. 1-channel system: approx. 1 second 82-channel system: approx. 1.5 seconds When multiple transmitters are performing roaming Time per unit x number of units (approximate calculation) For example, when 50 transmitters are roaming concurrently, all connections will be established after about 50 seconds. (In-house data) Note When there is a mix of ST mode and NT mode systems or when there are multiple NT mode systems, the roaming time may change, depending on the installation environment. Cross Remote Technology 25 Technology Cross Remote Features Cross Remote can be operated in two modes, ST mode and NT mode, to fit different system requirements. NT M This section explains the features of ST mode and NT mode, and of the Wireless Studio application designed for monitoring and controlling transmitters. ST Mode Features In ST mode, the transmitter and receiver communicate directly in a one-on-one configuration. When the receiver is placed within a main link service area, Cross Remote can be used within a range of about 10 meters from the receiver. Featu Note Because the number of channels will increase when more equipment is introduced in ST mode, the NT mode should be selected when more than six transmitters are to be controlled. General communication flow Conne In ST mode, the receiver and transmitter communicate as shown below.

NT Mode Features Features of Remote Control Unit RMU-01 mode Connection to receiver is established via Ethernet (wired LAN). By installing the Wireless Studio application (supplied with DWR-R01D) on a computer and connecting this computer to the network, multiple transmitters can be monitored and controlled from the computer. Connection diagram (simplified) Computer used for monitoring RMU-01 Up to 9 units can be connected Hub Receiver Up to 41 units can be connected General communication flow In NT mode, the receiver and transmitter communicate via the RMU-01, as shown below.

This enhances convenience during simultaneous multi-channel operation. In ST mode, a paired receiver and transmitter operate in a one-on-one configuration. This will lead to channel congestion when the equipment count increases. In NT mode on the other hand, the transmitter and receiver communicate via the RMU-01. Because the RMU-01 controls the overall communication volume on the remote control channels, congestion can be avoided also when equipment count increases.

Cross Remote Features 29 Technology Cross Remote Precautions Co D This section provides information about various points to keep in mind when setting up and operating a Cross Remote This se system. suppo Ensuring a Stable Service Area Syste In the Cross Remote service area, the two wireless signals for the main (UHF) link and remote control (2.4 Ghz) link must be available together. Equipment must be installed in such a way as to ensure that the main (UHF) link and remote control (2.4 GHz) link wireless signals will not be interrupted in the Cross Remote service area. When installing main link equipment including antenna, receiver, and remote control unit, the possibility of interference from other equipment should be taken into consideration. Design the installation so as to minimize the risk of interference from TV broadcast transmission, other wireless systems, and common frequency channels within the same wireless microphone system. If interference is occurring, increase the distance between the interference source and the wireless microphone system, turn power to the interference source off, or take other suitable measures. Regarding the remote control link, the interference risk from other equipment using the 2.4 GHz band should be taken into consideration. Increase the distance of the wireless microphone system to possible interference sources and select equipment to avoid the possibility of simultaneous operation of other 2.4 GHz equipment. ST mode: Uses 2.405 GHz (11ch), 2.425 GHz (15ch), 2.450 GHz (20ch), and 2.475 GHz (25ch). When there is other equipment that uses the 2.4 GHz band, these channels should be avoided. NT mode: Uses 2.420 GHz (14ch), 2.445 GHz (19ch), and 2.470 GHz (24ch). When there is other equipment that is using the 2.4 GHz band, these channels should be avoided. 2.4 GHz band radio wave propagation is highly linear and not easily deflected. When people or objects are present in the path between the remote control unit and transmitter, reception field strength may decrease drastically. Always try to ensure a direct line of sight between remote control unit and the wireless microphone and transmitter. To ensure stable transmission of 2.4 GHz band signals and prevent adverse influences from blocking by obstacles, it is recommended to use a minimum of two RMU-01 remote control units. When multiple units are used, the distance between installation locations should be about 10 to 20 meters. Up to nine remote control units can be used within one system. When multiple remote control units are used simultaneously, they should be spaced at least 10 meters apart. The equipment should be kept as far as possible from wireless LAN access points or other equipment using the 2.4 GHz band. In NT mode, the whip antennas supplied with the Digital Wireless Receiver DWR-R01D cannot be used. (When the receiver detects a remote control unit, it automatically switches to NT mode.) When there is an adjacent system using NT mode, add a remote control unit to the current system and also operate it in NT mode. Preventing Interference Main (UHF) link precautions Design the installation so as to minimize the risk of interference from TV, other wireless systems, and common frequency channels within the same system. Select channels so as to prevent interference If interference is occurring, increase the distance between the interference source and the wireless microphone system, turn power to the interference source off, or take other suitable measures. Remote control (2.4 GHz) link precautions 30 Design the installation so as to minimize the risk of interference from other devices that use the 2.4 GHz band, and be wary of close proximity between devices and simultaneous use of multiple devices. WiFi and Bluetooth and other applications also use the 2.4 GHz band. Special care must be taken in locations where large numbers of people congregate, such as at trade shows etc. Also take care to avoid interference from wireless remote controls for lighting appliances.

It can also be mounted on a camcorder, and two units can be linked for 4-channel operation. describ Syste System DC IN (external power input) connector (4-pin) Connect to the external power output connector of the camcorder using the supplied DC power cable. This connector accepts the power voltage between 10 V DC and 17 V DC. Audio output can be switched to analog or AES/EBU digital output. AES/EBU digital output carries two channels over a single cable. Channel 1 can be analog, even if channel 2 is used as digital output. (Analog UHF Synthesizer Tuner Unit WRR-855S is also supported, but the AES/EBU digital output and analog output in channel 2 cannot be used.) Front WORD SYNC (word sync input) connector (BNC type) Accepts external sync signal. When the DWR-S01D is attached and the sync signal is input, the DWR-S01D can be operated in synchronization with the whole audio system. Note that this connector does not work when the WRR-855S is attached. Note Even when the 75-ohm termination has been added on the DWR-S01D, this connector still works as the high-impedance input connector while the DWR-S01D is turned off. Monitor output selector Selects the audio output from the PHONES connector. 1: Outputs the audio from the OUTPUT1 connector to the L/R channels. 1+2: The audio from the OUTPUT1 connector is mixed with the audio from the OUTPUT2 connector (only when the OUTPUT2 connector is set to output analog signal) and output to the L/R channels. 2: Outputs the audio from the OUTPUT2 connector (only when the OUTPUT2 connector is set to output analog signal) to the L/R channels. When the WRR-855 is attached, no audio is output from the PHONES connector. Note Monitor output is split from the analog signal output to the OUTPUT1/2 connectors. When audio that is output to the OUTPUT1 connector is changed on the DWR-S01D using the ANALOG OUTPUT1 function, monitor output changes accordingly.

DC and Because the DWX system uses RF transmission in the UHF band, similar to analog wireless systems, antenna cables of an existing analog wireless system can be used, provided that the frequency matches. When operating the DWX system along with an analog wireless system, antenna cables can be shared. The DWR-R01D is supplied with two whip antennas. If the service area is small, you can also use the supplied whip antennas, but for better reception performance, using the optional UHF AN-820 or AN-01 UHF antennas is recommended. Select the antenna system according to the scale and purpose of your application. The supplied whip antennas can be mounted either on the front panel or the rear panel. hed ed in S is Whip antenna (supplied) Notes In applications such as on-stage use where the required RF directivity is known, or when used in conjunction with in-ear monitoring where unneeded directions are known, use the directional AN-01 antennas and install them with a suitable orientation.

Antenna Installation Requirements The antenna installation conditions for the DWX system are basically the same as for analog wireless systems. Consider the following points when planning an installation. The transmission distance of a wireless system will differ greatly, depending on factors such as how the equipment is worn on the body, the presence of obstacles, etc. Before finalizing an installation, be sure to check the reception condition, as described in “Checking the RF Level (UHF)” (page 45). BNC cables The connection between antenna and receiver is made with BNC cables, as in an analog wireless system. If there are existing cable installations from an analog wireless system, these can be used. BNC cable types Wireless microphone systems commonly use BNC cables for antenna connections. There are a number of standards for BNC cables, with different specifications for impedance and cable gauge (attenuation characteristics). For example, in a standard classification such as “5C-2V” and “8D-2V”, the first numeral indicates the cable gauge (thickness), and the subsequent letter indicates the impedance: “C” stands for 75 ohms and “D” for 50 ohms. Both for analog wireless systems and digital wireless systems, Sony recommends “5D-2V” -- “8D-2V” cables with 50-ohm impedance because these have lower transmission losses. 75-ohm BNC cables can also be used. When configuring a system in venues with existing cables, 75-ohm cables can also be used. When a DWX receiver is connected to a 75-ohm cable, in principle there will be a transmission loss due to impedance mismatching, but this loss amounts only to a few decibels. Because this is smaller than the loss introduced by the cable length, it often can be disregarded. Not only BNC cables but also BNC connectors come in two types, rated either for 50 ohms or 75 ohms impedance. When a 75-ohm cable is connected to a 50-ohm connector, an impedance mismatch occurs, but in practice this is often disregarded because the influence is small. More important than the difference between 50 ohms and 75 impedance are differences in signal losses introduced by two cables of different length. (With a 5D-2V cable, a 10-meter difference amounts to a difference of about 3 dB.) For information on available distances under different conditions, see “Distance between transmitter and antenna” (page 43). Note When configuring a new system, the use of 5D-2V -- 8D-2V BNC cables is recommended. 40 UHF System Configuration Number of antennas and diversity reception Use two identical antennas enuator election The DWX system, like the conventional analog wireless system, uses the space diversity reception principle. Two antennas are employed to receive the signal, with the system automatically switching to the antenna with the stronger signal. To ensure stable reception, the two antennas must be identical. — tch en it to 0 One may think that the further the two antennas are apart, the better the reception performance, but this is not necessarily true. It is usually not necessary to maintain a large distance between the antennas. Of course, if the antennas are too close to each other (less than 1 meter (3.2 ft.)), the advantages of the diversity system will be lost, but since the wavelength of a radio wave in the 600 MHz band is about 50 centimeters (1.6 ft.), ensuring a distance of about 3 to 5 times the wavelength (1.2 to 2 meters (3.9 to 6.6 ft.)) will usually result in good diversity reception. The distance should generally be kept well below the maximum of 20 meters (65.6 ft.), because performance will decrease above this point. Use shorter, thicker BNC cables of identical length To minimize transmission losses, the BNC cables should be as short and large-gauge as possible. If there is a difference in cable length, differences in cable loss can degrade the diversity effect. Make sure that both BNC cables are of the same length. tems. to m. mber ation Use two antenna sets (4 antennas) in large venues In large venues where two antennas do not provide sufficient coverage, and in cases where there are spots without direct line of sight between transmitter and antenna, the UHF Antenna Divider WD-850 should be used to allow for two sets of antennas (total 4 antennas). If venues such as banquet halls are partitioned into separate sections, a separate antenna installation should be provided for each section. In some cases, partition panels may incorporate metal plates for sound proofing, which may also block radio transmission. Special care is required in such instances. However, simply increasing the number of antennas is not always the answer, and an excessive number of antennas (such as 3 or 4 sets) may lead to mutual interference and thereby degrade reception performance. Multiple dividers make it possible to use antennas for other systems, but the number of antennas receiving the same RF signal should be kept to no more than two sets. (In a small venue, even two antenna sets may result in decreased reception performance. Always check actual performance before starting operation.) he ms cables a DWX ance oduced ms h losses oa d UHF System Configuration 41 Configuring a DWX System Spacing between antennas: 1 to 20 meters (3.2 to 65.6 ft.)

RF power 10 mW 1 mW Transmission distance 60 m (196.9 ft.) 20 m (65.6 ft.) If the transmitter is located too close to the antenna, input overload may occur, leading to intermodulation distortion and noise. A distance of at least 2 to 3 meters between transmitter and antennas should always be maintained. If the transmitter and antenna are too far apart, the service area will become doughnut-shaped. Installation should allow direct line of sight from transmitter to antenna There should be no obstacles between the transmitter and antennas. Normally, the antennas should be mounted at a height above average human height, looking up from the transmitter at an inclined angle. Keep away from windows If wireless systems are operated on several floors of a building, antennas near windows may cause interference between floors. For installation in high-rise buildings, antennas should be positioned at least 3 meters away from windows. On higher floors, radio signals from other microphones may interfere with reception even over considerable distances. Keep a clearance of several tens of centimeters from the ceiling Close proximity to the ceiling can cause reflections that negatively affect reception sensitivity. When installing antennas in corners, also keep a clearance of several tens of centimeters from adjacent walls. Locations to avoid Do not install antennas in the following types of locations. Otherwise signal reception may suffer or noise may occur. Behind ceiling or wall finishing layers Near windows, metal frames/plates, or electric appliances (lighting fixtures, motors, elevators, power distribution panels, etc.) Near electronic equipment (computers, dimmers, TV sets, video cameras, etc.) Install antennas with correct orientation The sensitivity pattern of an antenna extends in the horizontal direction from the correct mounting orientation. For example, if the AN-820A is mounted to the ceiling pointing down, reception sensitivity may decrease. 42 UHF System Configuration Booster gain setting conditions Configuring a DWX System ulation ways BNC cables used with UHF antennas should have low losses. To obtain the proper diversity effect, the cables should in principle be kept as short and large-gauge as possible, and should have the same length. If BNC cables need to be run over long distances, you should use an antenna booster to compensate for cable transmission losses. The table below shows the relationship between BNC cable length and gain settings. However, depending on usage conditions, RF level may be insufficient even if these recommendations are followed. Always check actual operation before finalizing a setting. * When transmitter output is 10 mW and the distance between the transmitter and antennas is approx. 30 m (98.4 ft.)

Gain 0 dB 10 dB 18 dB Note Antenna boosters are basically intended only to cover cable losses. High gain settings exceeding the cable loss compensation requirements may actually result in a smaller service area during simultaneous multichannel operation, due to increased intermodulation. For example, when antenna input level is raised, the range from the antenna to the transmitter increases, but the distance by which the transmitter has to be kept from the antenna also increases. If taking measures to optimize performance when the transmitter is at a maximum distance from the antenna, care must be taken so that the performance of the transmitter when it is closest to the antenna is not impaired. If the antenna booster gain is raised, and a transmitter operating simultaneously is brought in close proximity to the antenna, the reception performance of the distant transmitter may deteriorate.The DWX series provides an array of functions including transmitter RF power switching, antenna booster gain switching, and switching of the RF attenuator integrated in the Digital Wireless Receiver DWR-R01D. This allows flexible optimization of the service area. Use these functions to establish the settings required for the respective application.

Determine the channel most susceptible to third-order intermodulation distortion (this channel is subsequently called desired channel) and perform an operation test with the desired channel (single channel). Determine antenna installation positions and orientation that will be difficult to change later, and decide on number of antennas and gain settings. Using the desired channel only, assign a range of parameters for TX RF power and RX attenuator settings, and check coverage of the intended service area with each setting. Power up all transmitters for channels other than the desired channel, and generate thirdorder intermodulation distortion (subsequently called interference) in the receiver for the desired channel. Assign a range of parameters for TX RF power and RX attenuator settings and check the interference noise level with each setting. Using settings established as acceptable in steps 1 – 4, power up all transmitters and check the service area for the desired channel. If the service area for the desired channel is achieved, the service area for other channels should also be equal or better. Checking the RF Level (UHF) The RF level at which the receiver receives signals can be checked using the display of the Digital Wireless Receiver DWR-R01D or the RF level meter of Wireless Studio.

Procedure 1 Power down all transmitters. 2 Determine the channel plan for the receiver. Select the band Select the band based on your intended purpose and your wireless environment (e.g., whether TV broadcast transmissions exist). * The band is fixed for the DWR-S01D. Take factors such as effective use of frequencies and the risk of mutual interference with other wireless equipment and/or analog wireless systems into consideration. Select the group There are groups that are designed for simultaneous multi-channel operation and others that are not. Select an appropriate group according to the intended purpose and the number of channels to be operated simultaneously. Groups not specifically designed for simultaneous multi-channel operation are 00 for US models, 00 for EU models, and groups that include TV channel names (e.g., TV62). In order to accommodate flexible channel planning even when using these groups, continuous channel setting is possible in 125-kHz steps (25-K steps for groups that include TV channel names on EU models). When using these, design your own channel plans according to specific requirements. 3 Check for external interference. Sample settings for checking Band to use: To be established in this step.

Take factors such as the number of bands used and whether TV broadcast transmissions exist into consideration when selecting the group. For details on the groups that can be selected, see “Sony Digital Wireless Microphone System Frequency Lists” (PDF). * When simultaneous multi-channel operation is realized with a mix of analog wireless and digital wireless systems, the frequency spacing between the analog and digital systems must be at least 375 kHz. Therefore certain channels will not be available for selection in the digital wireless system. a ng that sition” s out.). Making and Checking RF Settings (UHF) 47 Configuring a DWX System Note If the computer on which Wireless Studio is installed, a Bluetooth mouse, or similar device is set up on top of the DWR-R01D and operated, the RF meters on the DWR-R01D may light up due to noise from the computer or other device. In such cases, distance the computer or other device from the DWR-R01D until the RF level meters turn off. Configuring a DWX System Step 2 Antenna Installation and Setup Select the channel with the most difficult conditions as the desired channel, and perform an operation test with the desired channel (single channel). Determine and optimize antenna installation positions and orientation that will be difficult to change later, and decide on number of antennas and gain settings. Procedure Selecting the desired channel 5 Power up all TX except one, and position the TX within the envisioned service area at the location closes to the antenna. Example: In a 12-channel system, turn one TX off and turn the eleven other TX on. * Equipment other than TX (RX, boosters, etc.) should be constantly on. 6 Use the RF level meter on the RX that is being set up to check the level of third-order intermodulation noise in the channel of the TX that is off. Sample settings for checking (RF raised to make noise easier to detect) Band to use: Band established in step 1. Group to use: Group established in step 1. Antenna installation location/orientation: Refer to “Antenna installation position” (page 43). Antenna gain: Refer to “Booster gain setting conditions” (page 44). Number of antennas: Refer to “Antenna installation position” (page 43). TX RF power: 10 mW RX attenuator: 0 dB Checking procedure Check the RF level meter indication. 7 Power down a different TX and repeat steps 5 to 6. Check all channels. Example: In a 12-channel system, perform the procedure 12 times. 8 Designate the channel with the highest noise level as the desired channel. Note When using multiple RX units in a cascaded configuration, the third-order intermodulation noise of each RX will be added up, so that noise may be highest at the last channel. * However, this depends on the channel plan and the number of channels, and may not always apply. Noise in last channel may be highest 48 Making and Checking RF Settings (UHF) Antenna installation and setup nd 9 Power up only the desired channel TX and establish a setup simulating the expected conditions during actual operation. Example: If the TX is the DWM-01, it should be held in the hand, close to the mouth. If the TX is the DWT-B01, it should be worn on the hip. * Equipment other than TX (RX, boosters, etc.) should be constantly on. the Configuring a DWX System 10 Move the desired channel TX throughout the service area, and check for the presence of obstructions, dropout points, and body effect. Sample settings for checking Band to use: Band established in Step 1. Group to use: Group established in Step 1. Antenna installation location/orientation: To be determined in this step. Antenna gain: To be determined in this step. Number of antennas: To be determined in this step. TX RF power: 1 mW RX attenuator: 10 dB Checking procedure Check that the RF indicator is lit green. * In this step, we recommend adjusting the setup, direction, and number of antennas to obtain the highest possible RF level. 11 Even at points with weak RF levels, optimize the antenna setup conditions so that the RF level is at its highest, and check the service area again. Determining the antenna installation location/orientation: As close as possible to service area *1 As far as possible, ensure direct line of sight to TX (directional antennas should be pointed to the farthest point of the desired area) As far as possible, antennas should overlook service area Adjust antenna location/orientation to maximize the service area. Determine antenna gain*2*3: 0 dB, 10 dB, or 18 dB (should cover cable loss but not be excessively high) Determine number of antennas: 2, or 4 f each *1 Too short distance between TX and antenna can also result in reception degradation, due to RF input overload and thirdorder intermodulation distortion. Recommended TX to antenna distance for 3-channel operation is about 3 meters, and for 10-channel operation 5 meters or more. *2 Antenna gain must be set to the same value on both antennas, to obtain the diversity effect. *3 When using the AN-01 antenna, you can set gain on the antenna to “Auto” and control gain by switching the DWR-R01D booster power supply voltage. This makes it easier to change settings also after installation. (AN-820 supports Auto only.)

Yes To Step 3 50 Making and Checking RF Settings (UHF) No Step 3 Checking the Service Area With One Channel Using the desired channel subject to severe conditions, assign a range of parameters for TX power output and RX attenuator settings, and check whether the settings result in coverage of the intended service area. Procedure Example: If the TX is the DWM-01, it should be held in the hand, close to the mouth. If the TX is the DWT-B01, it should be worn on the hip. * Equipment other than TX (RX, boosters, etc.) should be constantly on. 13 Make the parameter settings, and move the desired channel TX throughout the service area, checking at various locations. Sample settings for checking Band to use: Band established in step 1. Group to use: Group established in step 1. Antenna installation location/orientation: As determined in step 2. Antenna gain: As determined in step 2. Number of antennas: As determined in step 2. TX RF power: To be determined in this step *1 (settings 1 to 6 in table below) RX attenuator: To be determined in this step *1 (settings 1 to 6 in table below) RX ATT 10 dB 5 dB 0 dB 1 mW Setting 1 Setting 2 Setting 3 TX RF power 10 mW Setting 4 Setting 5 Setting 6 As 50 mW output of the TX produces high third-order intermodulation distortion, it is not suited for simultaneous multi-channel operation. Therefore, 50 mW output is excluded from the items for checking. Checking procedure Check the following: No dropouts in audio signal RF indicator lit in green QL meter shows more than 4 segments *1 When multiple TX are used in step 4 and following, changing the TX RF power for a high number of channels is time-consuming. On the other hand, changing the RX attenuator setting can be done at the first DWR-R01D of the cascaded configuration and is therefore relatively easy. To simplify the procedure, you can first perform steps 3 to 5 by changing the RX attenuator setting only, and then change the TX RF power and repeat steps 3 to 5. Sample results RX ATT 10 dB 5 dB 0 dB TX RF power 1 mW 10 mW Setting 1: Poor Setting 4: Good Setting 2: Fair Setting 5: Good Setting 3: Good Setting 6: Good Making and Checking RF Settings (UHF) 51 Configuring a DWX System 12 Power up only the desired channel TX and establish a setup simulating the expected conditions during actual operation. Configuring a DWX System Step 4 Checking Third-order Intermodulation Distortion Step Power up all transmitters for channels other than the desired channel, and generate third-order intermodulation distortion (subsequently called interference) in the receiver for the desired channel. Assign a range of parameters for TX output power and RX attenuator settings and check the interference noise level with each setting. Procedure Proce 14 Power up all transmitters for channels other than the desired channel. Establish a setup simulating the expected conditions during actual operation, and have a person with the TX stand in a position closest to the antenna. Example: If the TX is the DWM-01, it should be held in the hand, close to the mouth. If the TX is the DWT-B01, it should be worn on the hip, and the person should stand at the rim of the stage, approaching the antenna. * Equipment other than TX (RX, boosters, etc.) should be constantly on. 15 Using the RF level meter of the RX set to the channel whose TX is switched off, check the thirdorder intermodulation distortion noise level in the channel. Setting example for checking Band to use: Band established in step 1. Group to use: Group established in step 1. Antenna installation location/orientation: As determined in step 2. Antenna gain: As determined in step 2. Number of antennas: As determined in step 2. TX RF power: Setting that cleared the requirements of step 3. RX attenuator: Setting that cleared the requirements of step 3. Check procedure Check the RF level meter indication. In principle, the noise level should be less than 10 dBμ (RF level meter should be consistently out). Sample results 10 dB RX ATT 5 dB 0 dB TX RF power 1 mW 10 mW Step 3 Step 4 Step 3 Step 4 Setting 1 Setting 4 Poor (Good) Good Good Setting 2 Setting 5 Fair (Good) Good Good Setting 3 Setting 6 Good Good Good Fair Note For stable reception, sufficient RF power levels should be obtained in the desired channel, and at the same time, the D/U ratio between desired channel and interference should be at least 20 dB. Decreasing the system-wide RF level will decrease interference in the desired channel by a factor of 3. Consequently, if the D/U ratio is insufficient, reducing the RF lower will provide an improvement. For example, when a 5 dB attenuation is introduced, the level in the desired channel will decrease by 5 dB, but the interference level will decrease by 15 dB, thereby yielding an improvement in D/U ratio by 10 dB. The same applies to the attenuation of RF power due to distance. If the RF level is too low, the available distance will decrease, resulting in an insufficient service area. But if the RF level is very high, this also can cause problems because the required D/U ratio cannot be obtained in the antenna vicinity. The resulting service area will be shaped like a doughnut, with a large hole in the middle, which also is undesirable. Therefore, 50 mW output of the TX is not suited for simultaneous multi-channel operation. TX RF power Low High Low High RX ATT A Third-order intermodulation distortion noise level B C Low High Small Zone A Interference is low, but RF level in desired channel is also low, resulting in insufficient service area. 52 Making and Checking RF Settings (UHF) Service area for single channel Zone B Good balance between desired channel and interference RF level. Desired service area is achieved, also during simultaneous multi-channel operation. Large Zone C RF level in desired channel is high, but interference level is also high. During simultaneous multi-channel operation, desired service area will not be achieved in antenna vicinity. Service area Step 5 Checking Simultaneous Multi-channel Operation Using settings established as acceptable in steps 1 – 4, power up all transmitters and check the service area for the desired channel. If the service area for the desired channel is achieved, the service area for other channels should also be equal or better. By checking the service area with multiple sets of parameters, the degree of leeway can be established. You should then select the optimal parameters for operation. sign level e TX m of the 16 Power up all transmitters.

Operation Check Check the following: No dropouts in audio signal At least 2 segments of RF indicator shown throughout RF indicator lit in green QL meter shows more than 4 segments 18 Check the service area with multiple combinations of TX RF power and RX attenuator settings. Then select the combination that best matches the anticipated operation conditions. Sample results asing ntly, a5 nce s to ease, ecause haped of the 10 dB RX ATT 5 dB 0 dB TX RF power 1 mW 10 mW Step 3 Step 4 Step 5 Step 3 Step 4 Step 5 Setting 1: Zone A Setting 4: Zone B Poor (Good) (Poor) Good Good Good Setting 2: Zone A Setting 5: Zone C Fair (Good) (Fair) Good Good Good Setting 3: Zone B Setting 6: Zone C Good Good Good Good Fair (Fair) For example, with a result such as shown above, settings 3, 4, and 5 will produce a Zone B type service area which meets the requirements. Either of these settings can be chosen. However, with setting 4 the RF level margin is smaller than with setting 5. Taking the possible influence of the body effect into consideration, settings 3 or 5 therefore are a better choice for stable operation. With setting 3, the transmitter output is 1 mW. Compared to the 10 mW of setting 5, battery life will be extended by about 10 to 20 percent. With setting 5, the transmitter output is 10 mW. Compared to the 1 mW of setting 3, the higher RF level is more suitable for situations with a lot of movement. It is also possible to use setting 3 as a general system setting, and increase the RF level to 10 mW only in one or more specific channels with lots of movement, to enlarge the service area for these channels. However, because third-order intermodulation distortion will increase in this case, and channels that may be affected should be checked beforehand. For safety, operation in all channels should be checked before going into operation.

Yes To Case 2 Case 1: RF level is too low (15 dBu or less, RF indicator frequently turns red) If only the RF level of a specific receiver is low, increase the RF power of the corresponding transmitter. If the RF levels of all receivers are low, perform one of the following. Increase the RF power of all the transmitters. Decrease the RF attenuator settings of the DWR-R01D and other peripheral devices. Increase the RF level settings of the AN-01, AN-820A, and other peripheral devices. Case 2: RF level is too high (RF indicator frequently turns orange)* If only the RF level of a specific receiver is high, decrease the RF power of the corresponding transmitter. If the RF levels of all receivers are high, perform one of the following. Decrease the RF power of all the transmitters. Increase the RF attenuator settings of the DWR-R01D and other peripheral devices. Decrease the RF level settings of the AN-01, AN-820A, and other peripheral devices. * The indicator turns orange when the RF level is too high (80 dBu or more) only on the DWR-R01D. Case 3: Interference may be picked up To check this, perform the following steps. Turn power to all transmitters off. In this condition, monitor the RF level on the display of the DWR-R01D or in Wireless Studio. If the RF level meter registers by one segment or more, take measures to eliminate interference, or change to another available channel within the same group. Making and Checking RF Settings (UHF) 55 Configuring a DWX System N Use of Quick Check Cross R When there is not enough time for a step-by-step configuration of the system, such as during an event or concert, check the following three items to verify that the system has been configured properly. Syste Conditions for checking Perform the check after confirming that all antennas and cables are installed, settings for the antenna gain, TX RF power, RX attenuator, and used frequencies are configured, and the RX equipment is turned on. System Turn off all TX equipment, and check that RF level meters for all RX equipment are off (i.e., not lit). Turn on all TX equipment except one, check that the RF level meters are off (i.e., not lit) for the RX with the same frequency as the TX that is turned off, and repeat this check for each TX. Turn on all TX equipment, and check that the RF indicators for all RX equipment are always lit green under all envisioned conditions. ST mo Items for checking If all the above conditions are met, you can reliably operate the system without concerns. If there is not enough time to check all envisioned operating conditions ’ Turn on all TX equipment, and check that the RF level meters for all RX equipment show 4 to 6 segments under the normal state (i.e., normal installation at a fixed position). If the conditions for , , and ’ are met, you can operate the system with reasonable reliability. Note The body effect has an influence of 10 dB to 20 dB. If the body effect is not present under the normal state, the addition of the body effect will result in a drop of 10 dB to 20 dB. If the body effect is present under the normal state, the loss of the body effect will result in an increase of 10 dB to 20 dB. If the RF level meters show 5 segments under the normal state, the addition or loss of the body effect will result in a showing of 3 or 7 segments respectively, leaving you with an RF level that provides reasonable reliability (RF indicator is lit green). If conditions are not met If condition is not met, interference exists. Remove computers, Bluetooth mice, mobile phones, game devices, and other signal transmitting devices away from the area. If the problem persists after removing the above, interference from another system may be present. Perform a clear channel scan, and reselect a frequency without interference. If condition is not met, third-order intermodulation distortion exists, but as long as condition ③ is met, you can reliably operate the system. In addition to checking condition in such cases, check that the QL meter always shows more than 4 segments. If time allows, check that conditions and are met after adjusting the antenna setup positions, antenna gain, attenuator, and TX output levels to ensure even more reliable operation. 56 Making and Checking RF Settings (UHF) Opera Network System Configuration Use of the Remote Control Unit RMU-01 and a computer on which Wireless Studio is installed allows configuration of a Cross Remote network with expanded functions. r System Configuration System Requirements Configure a dedicated LAN for the DWX system using 100Base-TX/10Base-T Ethernet equipment. Do not use an existing LAN. Make sure that IP addresses of equipment do not conflict. Operation is not guaranteed for connections utilizing wireless LAN access points. h the ST mode and NT mode under The Sony digital wireless system supports two types of remote control: ST mode where a transmitter and receiver communicate directly in a one-on-one configuration, and NT mode where the transmitter and receiver communicate via the RMU-01 connected to the network. System configuration for ST mode ments Transmitter and receiver communicate directly in a one-on-one configuration. When the receiver is placed within a main UHF service area, Cross Remote can be used within a range of about 10 meters from the receiver. Notes Within a single Cross Remote service area, control should be limited to six transmitters (three receivers). To control more than six transmitters, the NT mode system should be used. As the DWR-S01D is not equipped with a network terminal, it can only operate in ST mode. The DWR-R01D allows connection of a computer and use of Wireless Studio for transmitter monitoring and control also in ST mode. state, r the rs g of 3 tor is lit game oving eselect met, an 4 System configuration for NT mode Transmitters and receivers communicate via the Remote Control Unit RMU-01 connected to a network. One RMU-01 unit can control up to 82 transmitters. The service area range is about 10 meters from the Remote Control Unit RMU-01. Up to nine RMU-01 units can be used within a system, which allows expanding the service area. Notes If at least one RMU-01 unit is connected to the system, remote control always operates in NT mode. Keep in mind that the internal 2.4 GHz antenna of the DWR-R01D ceases to operate in NT mode. The DWR-S01D does not support NT mode. Operation from receiver and operation from computer Transmitter monitoring can be controlled from a receiver or from a computer on which Wireless Studio is installed. Operation from receiver Transmitter monitoring can be controlled while checking the transmitter settings on the receiver display. When the DWR-S01D is mounted on a camcorder, operation from the camcorder menu screen is also possible. Note Although the built-in 2.4 GHz antenna of the DWR-R01D will stop functioning in NT mode, remote control from the DWR-R01D is still possible, without the use of a computer. (Operation in conjunction with a computer is also possible.) Operation from a computer Transmitter monitoring can also be controlled from a Windows computer that has the Wireless Studio application installed. Up to 6 computers can be used in a single system. Note Transmitter monitoring control is also possible via a connected computer in ST mode (DWR-R01D only). (Refer to Figures 3 and 4 in the “System configuration examples” section.)

This sec Cover The inte propag and tra establis Note The ma the num system. The rad meters, 01 units should What is PoE (Power over Ethernet)? PoE allows powering a device over the Ethernet cables used in a LAN. Because data and power are routed through a single cable, installation of equipment is facilitated even in locations where providing a conventional power supply would be difficult. The RMU-01 can be powered from an IEEE802.3af compliant hub with PoE support, or by connecting a PoE power supply between a regular hub and the RMU-01. LAN cable information Use Category 5 or better LAN cable for connecting the RMU-01 or DWR-R01D to the computer. The maximum allowable cable run is 100 meters. If longer cable runs are required, use a hub between the computer and the RMU-01 or DWR-R01D. Depending on the connection configuration, use the following type of cable. Direct connection to computer: Crossover cable Connection via hub: Straight cable When in signal a Installa When tw pack tra is recom body-pa transmi Installation of Remote Control Unit RMU-01 This section provides information about the coverage area, roaming times etc. when using the RMU-01 for wireless communication. th the Coverage area of Remote Control Unit RMU-01 Configuring a DWX System The internal antenna of the RMU-01 emits a strong circular-pattern RF signal centered on the antenna axis. 2.4 GHz band radio wave propagation is highly linear and not easily deflected. When people or objects are present in the path between the remote control unit and transmitter, reception field strength may decrease drastically. Always try to install the RMU-01 so that a direct line of sight can be established from the wireless microphone or transmitter. Note The maximum number of RMU-01 units in a single network system is nine, but increasing the number of RMU-01 units will not increase the number of transmitters that can be used. Regardless of the number of RMU-01 units, the maximum number of transmitters is 82 per system. 2.3af AN The radius of the area where RF signals are strong is about 10 meters, centered on the antenna. When using multiple RMU01 units to enlarge the coverage area, these concentric areas should overlap. Installation example 2 (plane view) To increase the total operation area by putting the areas that multiple RMU-01 units cover together, place them so that the area that one RMU-01 covers touches those on others, completely adjacent and with no gaps.

When two or more RMU-01 units are installed to enlarge the coverage area by overlap, and a transmitter moves out of the service area of one RMU-01 unit, roaming occurs and the connection switches to the other RMU-01 unit. The connection interruption due to the roaming action will occur also if there are no blanks, that is when the coverage area overlaps properly. Also when the number of coverage area points has been increased, a transmitter leaving the coverage area of one RMU01 and entering that of another, or re-entering the same RMU-01 coverage area will go through a roaming phase, and some time will be required for reconnection. The time required for roaming depends on the wireless environment and the number of transmitters. It can range from several seconds to several tens of seconds. 1) RMU-01 2) Transmitter 3) To make the most of the signal emission characteristics, install facing the front side (the side with SONY logo) downward. 4) Ceiling 5) Wall 6) Floor When one transmitter performs roaming in a normal communication environment The number of operation channels does not significantly change the roaming time. 1-channel system: approx. 1 second 82-channel system: approx. 1.5 seconds When multiple transmitters are performing roaming Number of coverage area points The coverage area can be enlarged by installing multiple RMU01 units with overlapping coverage areas, but if the number of locations to control is limited, it is not necessary that all areas overlap each other. Install RMU-01 units in the areas to be controlled, and increase the number of coverage area points. 62 Network System Configuration Netw Time per unit x number of units (approximate calculation) For example, when 50 transmitters are roaming concurrently, all connections will be established after about 50 seconds.

Power g oncert . Network Device Connections This section describes which LAN cables to use and how to supply power (PoE) when connecting each device in a network. LAN cable information Power supply (PoE) for Remote Control Unit RMU-01 The RMU-01 supports PoE (Power over Ethernet). PoE allows powering a device over the Ethernet cables used in a LAN. Because data and power are routed through a single cable, installation of equipment is facilitated even in locations where providing a conventional power supply would be difficult. When an IEEE802.3af compliant hub with PoE support is connected to the network, or when a PoE power supply is connected between the RMU-01 and a regular hub, the RMU-01 can be powered without requiring another power source. To supply power from the PoE hub RMU-01 PC PoE hub e f the tion ere are erly. DWR-R01D 1) Straight cable e RMUMU-01 me time from To supply power from the PoE power supply unit When only one receiver (such as the DWR-R01D) or the PC is connected to this unit and the power is supplied to this unit from the PoE power supply unit RMU-01 PoE power supply unit When multiple devices including this unit and the receivers are connected and the power is supplied to this unit from the PoE power supply unit RMU-01 PoE power supply unit PC Hub ly PoE power supply unit DWR-R01D 1) Cross cable 2) Straight cable DWR-R01D ation) r about or when may 1) Straight cable RMU-01 Notes The RMU-01 can also be powered from the supplied AC adapter. Be sure to use Category 5 or better LAN cable. The length of the LAN cable run between the RMU-01 and other equipment (PoE hub, receiver, etc.) should not exceed 100 meters. If a PoE power supply without repeater capability is inserted between the RMU-01 and the target equipment (DWR-R01D, hub etc.), the combined LAN cable run to the RMU-01 should not exceed 100 meters. Network System Configuration 63 Configuring a DWX System Use Category 5 or better LAN cable, and keep cable length under 100 meters. If cable runs of more than 100 meters are required, use a hub or other suitable equipment. You can also use crossover cables for direct connections between the DWR-R01D, computer, or RMU-01, without the use of a hub. For details, refer to Figures 3 and 5 in the “System configuration examples” section, and to “To supply power from the PoE power supply unit” in the “Power supply (PoE) for RMU-01” section. Configuring a DWX System Making and Checking Network Settings Follow the steps described below to make network settings and check the Cross Remote functions. Step 1 Network setup Step 2 Checking equipment connections Step 3 Checking for 2.4 GHz interference Step 4 Checking the monitor function Step 5 Checking the control function 64 Making and Checking Network Settings Specify the IP addresses and subnet masks of the devices connected to the network. Verify that there are no IP address conflicts and that all devices connected to the network are correctly installed and set up. Use spectrum analyzer or WiFi analyzer application software to verify that there is no interference in the frequency bands used for Cross Remote. In a Cross Remote configuration, UHF reception forms parts of the network system. Use Wireless Studio to check transmitter information received via WiDIF-HP and passed onto the network. While checking whether the obtained service area fulfills the requirements, determine the installation location and number of RMU-01 units. 2.4 GH 2.4 GHz area operation check Checking with the DWR-R01D display Use the “Cross Remote” control condition indication to check whether the transmitter is in the 2.4 GHz area. “Cross Remote” control condition indication Configuring a DWX System re “Cross Remote” control condition indication e Indicates the signal transmission condition of the “Cross Remote” control function (four levels). : Good transmission : Somewhat good transmission : Somewhat poor transmission : Poor transmission : Unable to communicate with paired transmitter When the “Cross Remote” control function is off, this indication does not appear. Checking with Wireless Studio Use the “Cross Remote” control condition display to check whether the transmitter is in the 2.4 GHz area. “Cross Remote” control condition display “Cross Remote” control condition display Indicates the communication status of the paired transmitter according to four levels. : Good transmission : Somewhat good transmission : Somewhat poor transmission : Poor transmission (red indication): Unable to communicate with paired transmitter This icon does not appear when the “Cross Remote” function on the DWR-R01D is turned off. Making and Checking Network Settings 65 Configuring a DWX System Step 1 Network Setup Co Specify the IP addresses and subnet masks of the devices connected to the network. Network configuration Configure a dedicated network for the DWX system, using 100Base-TX/10Base-T Ethernet equipment. Do not use an existing network. System precautions and limitations Make sure that IP addresses of equipment do not conflict. Operation is not guaranteed for connections utilizing wireless LAN access points. IP address setup IP addresses must be configured for the computer, DWR-R01D, and RMU-01. The IP addresses should be unique within the same subnet. The values for the first three sets of numbers are identical for IP addresses (XXX.XXX.XXX.XXX) within the same subnet. Example: For IP addresses in the same subnet 192.168.0.100 and 192.168.0.20 Values for first three sets of numbers are identical. For IP addresses in different subnets 192.168.0.100 and 192.168.2.200 Values for first three sets of numbers are different. If IP addresses within different subnets are configured for the devices, the devices will not communicate properly even when connected to the same hub. Configure identical values for the first three sets of numbers as follows, and configure a unique value between 1 and 255 in the fourth set for each device. Configuration example: Computer: 192.168.0.10 DWR-R01D: 192.168.0.100 RMU-01: 192.168.0.200 Set the subnet mask to 255.255.255.0. Note The DWR-R01D and RMU-01 do not include a DHCP client function. Each device must have a fixed IP address. If there is an IP address conflict due to identical addresses, the system will not operate properly. Make sure that each device has a unique IP address. 66 Making and Checking Network Settings DW Computer network settings Use the regular procedure for the respective operating system to set the IP address and subnet mask of the computer. PC network settings The following procedure explains the setting operations using the Windows XP operating system. * For details on how to make network settings with other operating systems, refer to the help of the operating system that you use.

DWR-R01D network settings Configure the IP address and subnet mask for the DWR-R01D in the NETWORK submenu of the UTILITY menu. Note When IP address settings are changed, NT mode pairing settings are disabled. Perform the pairing process again. Making and Checking Network Settings 67 Configuring a DWX System RMU-01 network settings Step Install the setup tool supplied with the RMU-01 on the computer and make the RMU-01 network settings from the computer. Procedure Ch Start the RMU-01 setup tool on the computer. Click the [Search Devices] button. Note On some computers equipped with multiple LAN ports (either wired or wireless), the RMU-01 units connected to the LAN will not be detected even after you click the [Search Devices] button. In such cases, temporarily disable all ports including those for LAN and IEEE1394 connections via [Network Connections] on the operating system, and enable only the port to which the RMU-01 is connected. Then, restart the RMU-01 setup tool and perform auto detection again. RMU-01 devices present on the network are detected, and information about them is displayed. Select the device for which to make the setting, and click the [Setting] button. Specify the device name, IP address, and subnet mask. Set the first three fields to the same values for each device. Use a unique value for the fourth field only. Specify a different segment from other wireless networks in the vicinity. Set to 255.255.255.0 Select the model number of the transmitter to be controlled from the RMU-01 in [Target TX]. The optimal remote control channel will be selected based on the specified transmitter and appear in [Remote CH]. You can select [Custom] to freely select the remote control channel. If radio interference exists between the RMU-01 remote control and other systems such as wireless LAN, you may be able to avoid the interference by selecting the remote control channel with [Custom] enabled. Notes When [Custom] is selected, the automatic selection of the optimal remote control channel for the transmitter will be ignored. In such cases, signals from the transmitter may affect remote control. Be sure to verify operation before beginning actual use. Depending on the operating environment of your computer, certain operations may be blocked by the firewall or security filter after startup of the RMU-01 setup tool. If LAN communication that is necessary for operation in NT mode is blocked, the system will not operate properly. Therefore, configure the firewall or security filter to allow RMU-01 setup tool operations. 68 Making and Checking Network Settings Step 2 Checking Equipment Connections rom Verify that all devices connected to the network are correctly installed and set up. Checking the remote mode The display of the DWR-R01D can be used to check whether the receiver currently operates in ST mode or NT mode. Configuring a DWX System To show the remote mode on the display, press the RF REMOTE button on the front panel. cted arily perating and RF REMOTE menu button Remote mode indication Remote mode indication Display whether the receiver is operating in the ST mode or NT mode. (The mode can only be displayed.) NT: The receiver has recognized the RMU-01 unit and is operating in NT mode. ST: The receiver is operating in ST mode. SEARCH: The receiver is searching for the remote mode state. ed d ol e ure to he or or Making and Checking Network Settings 69 Configuring a DWX System Checking the equipment count Step Use Wireless Studio to check the type and number of devices connected to the network. If there are IP address conflicts such as address duplication, the actual number of devices and the number shown in Wireless Studio will not match. Procedure Power up all devices and set Wireless Studio to the online condition. A list of all devices on the network will be shown. In cases such as the following, the actual number of devices and the devices shown in the device list will not match: IP address conflicts, IP address settings with overlapping subnet masks, Ethernet cable disconnection, device not powered up, etc. Check the number of DWR-R01D and RMU-01 units in the device list. Step Device List window IP address conflict between DWR-R01D units The receiver section of the device list will only shown one DWR-R01D unit, so that the count does not match the actual number of units. IP address conflict between RMU-01 units The RMU section of the device list will only shown one RMU-01 unit, so that the count does not match the actual number of units. IP address conflict between DWR-R01D and DWR-R01D units The device list will only shown one device, either in the receiver section or the RMU, so that the count does not match the actual number of units. IP address conflict between computer and DWR-R01D, or computer and RMU-01 Wireless Studio cannot be set to the online condition, or the device list does not show the DWR-R01D or RMU01, so that the count does not match the actual number of units. IP address conflict between computers When the operating system detects an IP address conflict, an alert message will appear on one or both of the computers. IP address re-assignment Check the settings including those for other LANs and network connections as well as the settings within the same subnet, and verify that there are no IP address conflicts, IP address settings with overlapping subnet masks, or other problems. If necessary, re-assign IP addresses to the computer, DWR-R01D, and RMU-01 units, as described in “IP address setup” (page 67). Note Wireless Studio identifies the DWR-R01D and RMU-01 by IP address. The DWM-01/DWT-B01 are mutually identified by the DWR-R01D and MAC address. In order to allow later reloading and complete restoring of setting information saved in Wireless Studio, all equipment must be the same, and IP address settings also must match. 70 Making and Checking Network Settings Step Step 3 Checking for 2.4 GHz Interference ber k will Procedure Power down all DWX equipment so that no RF signals in the 2.4 GHz band are emitted by the DWX system. Use a spectrum analyzer or WiFi spectrum analysis application for PC, smart phone, or tablet PC to verify that there is no interference in the 802.11.4 band on channel 14 (2.420 GHz), channel 19 (2.445 GHz), and channel 24 (2.470 GHz). If there is interference, increase the distance between the system and interference sources, stop operation of the interference sources or move these to another frequency, to eliminate the interference. Caution The W-DMX wireless remote control system for lighting equipment and similar systems also may use the 2.4 GHz band. Pay special attention to such devices. Note If radio interference between wireless LAN or other systems cannot be avoided otherwise, you may be able to avoid interference by selecting the remote control channel with [Custom] enabled in [Setting] of the RMU-01 setup tool. When [Custom] is selected, the automatic selection of the optimal remote control channel for the transmitter will be ignored. In such cases, signals from the transmitter may affect remote control. Be sure to verify operation before beginning actual use. Step 4 Checking the Monitor Function In a Cross Remote configuration, UHF reception forms parts of the network system. Use Wireless Studio to check transmitter information received via WiDIF-HP and passed onto the network. Procedure Make suitable settings for frequency, security mode etc. so that the transmitter WiDIF-HP information can be received by the receiver. match Check the status of received transmitters using the display on the receiver. Check the status of received transmitters using the Wireless Studio screen. the If the transmitter status cannot be checked even if reception has been set up properly, there may be a problem with the UHF service area.
