II. CONTENTS
1. Product Overview
The CW-5HD is a wireless transmission device which transmits HD SDI video and
SDI audio with 5GHz band radio frequencies. CW-5HD TX is the transmitter, and
connects to a video source such as a video camera. CW-5HD RX is the receiver,
and connects to a monitor, for example. Video and audio from the video source
can be seen / listened to from a distance without cable connections. Where a
direct line-of-view is offered between CW-5HD TX and RX, the signals can be
transmitted up to 50m (with the transmit output power in HIGH mode).
Other features
zSupports HD-SDI/SD-SDI input and output.
zTransmitting HD video (1080i, 1080p, 720p) and SD video (525i/625i)
zSupporting SDI embedded audio. (Audio CH1 and CH2 only)
zTransmission delay is 1m/sec maximum.
zSignal protection by 256bit AES encryption (in UNICAST mode)
zThe adoption of ‘MIMO’, which multiplexes wireless signals via multiple
antennas in one channel, enables HD-SDI or SD-SDI transmission.
zBoth automatic and manual selection of transmitted frequencies (4ch).
zTwo-level select (HIGH/LOW) of transmit output power.
zPower can be supplied by V-Mount type Lithium Ion battery or by DC input,
via XLR 4P connector.
zBack up power failure function enables immediate and automatic switching
to a connected battery if the external DC connected power is disconnected.
＊ The transmission distance may vary depending on surroundings, radio wave conditions,
buildings, etc., the transmission distance of approximately 50m is not guaranteed.
＊ When CW-5HD is placed near a device such a TV, the TV image may be disrupted. Please
increase the distance between TV and CW-5HD when this happens
＊ In locations with many other devices operating in the 5GHz wireless bandwidth, CW-5HD
operation can be affected, and images may be interrupted.
＊ Signal reception may be affected by the position, height and angle of placement. If
reception is not stable, please physically adjust placement for the optimised signal.

3.2 CW-5HD Link Initialisation (common to TX/RX)
When the power switch of CW-5HD is turned on or the link of the transmitted
signal is lost, the CW-5HD TX and CW-5HD RX will start to search for each
other. The three LED lights will alternate on and off from bottom to top in
sequence, repeating this process until a link is established. This LED
alternating from bottom to top will indicate that the device is searching for a
link.
Searching（TX）：Green LED blinks on and off repeatedly
Searching（RX）：Green LED blinks on and off repeatedly

4. Selecting frequencies and power output
The CW-5HD TX is equipped with a FREQ SELECT switch and POWER MODE
switch. With the FREQ SELECT switch, the transmitted frequency is set. The
frequency selection is needed only on the TX. The frequency of the RX does
not have to be selected because RX searches for the transmitted frequency
automatically. POWER MODE switch changes the transmitted output to HIGH
or LOW.
4.1. Service frequencies and transmitted output
The service frequencies and the maximum transmitted outputs of CW-5HD
vary according to the designated regions.
The table below shows the service frequencies, corresponding channel
positions and the transmitted outputs for the EU region.
Region Channels

5. Link modes - UNICAST/MULTICAST
The UNI/MULTI switch is used to select the link mode. The UNI/MULTI select
switches on both the CW-5HD TX and CW-5HD RX must be set in the same
mode.
5.1. UNICAST mode（1:1 communication）
With UNI/MULTI switch in UNI position, CW-5HD links in UNICAST mode. In
UNICAST mode, the link is made only between the same serial numbered pair
of TX and RX (shipped as a pair). The transmitted signals are encoded by
256bit AES and can never be intercepted by other CW-5HD devices.

5.2. MULTICAST mode（1:n communication）
With the UNI/MULTI switch in MULTI position, the CW-5HD links in MULTICAST
mode, in which the CW-5HD TX can send video and audio to more than one
CW-5HD RX. In MULTICAST mode, the transmitted signals are not encoded by
256bit AES encryption.
There is no limit on the number of receiving CW-5HD RX in MULTICAST mode
as long as they are within reach of the transmitted signal and existing
environmental conditions are taken into regard.
Important Notes
zWhen more than one CW-5HD TX are transmitting in MULTICAST mode in
the same location, the CW-5HD RX will link with the first signal that it
receives.
zA single CW-5HD RX can not receive the signal from more than one
CW-5HD TX.

6. Operation guide
6.1. Set up
The CW-5HD does not include the various accessories that may be used in its
operation. Please separately access the following items as needed for your
specific application prior to use.
zBNC cable for HD-SDI or SDI signal connectivity
zIDX ENDURA system batteries or external power supply
Note: Power supply; Use only an AC adaptor, or batteries, with a DC
output of 11V – 17V. The CW-5HD DC-IN connector is XRL-4P male, pin
assign no.1: negative (-), no.4: positive (+). Do not apply over-voltage
or reverse-polarity voltage since they can cause failure or damage.
6.2. Operating procedures
①Connect CW-5HD TX to the video camera or other transmitting devices
battery source and CW-5HD RX to the receiving monitor’s battery mount.
If either device does not have a V-Mount, use the applicable adapter.
②Connect video device’s SDI output connector to CW-5HD TX SDI input
connector with a BNC cable. Next, connect the CW-5HD RX SDI output
connector to the monitor’s SDI input with BNC cable.
The CW-5HD TX has an SDI output connector, which can be connected to
a monitor for the video source if required. The CW-5HD RX has two
output connectors therefore two monitors, recorders, etc can be
connected simultaneously.
③Connect fully charged ENDURA batteries to CW-5HD TX and CW-5HD RX.
When an external power supply is used, connect to DC-IN connector.
Note: When an ENDURA battery is used, power is supplied to both
CW-5HD and video camera / monitors etc. When external power supply
is used at the DC-IN XLR, power is supplied only to CW-5HD. Video
camera, monitors etc must be powered from another source.
④Set the FREQ SELECT switch, POWER MODE switch, UNI/MULTI switch of
CW-5HD TX in appropriate modes. Set the UNI/MULTI switch of CW-5HD
RX in appropriate mode.
⑤Turn the power ON.

6.3. If reception is unstable
Signal reception may be affected by the position, height and angle of
placement. If reception is not stable, please look for the best condition by
adjusting the location, height, and other environmental variables.
When CW-5HD TX and RX are used close to each other, the received signal
becomes too strong and may disturb the video signal. When they are placed
close to each other (less than 3m as an example), set the POWER MODE
switch of CW-5HD TX to LOW.
6.4. Back-up power failure function
When an external power supply is used, power failure can be avoided by
mounting an IDX ENDURA battery to CW-5HD at the same time. If the
external power supply fails, use can continue via battery power. Depending on
certain conditions, video quality may be momentarily affected.
6.5. Power through function
When the CW-5HD is used with ENDURA batteries, the power supply to the
video camera, monitor, etc. will not stop even when the CW-5HD power switch
is turned off.
If the CW-5HD is not actually required for transmission it can remain on the
video source and turned off. The power from the attached battery will still
power the device even though the CW-5HD is turned off, saving battery
consumption.

7. Notes on Use
（１） The service frequencies and transmit power outputs of CW-5HD vary depending on the
designated regions, because each region has different local regulations or restrictions on
radio waves. The units are
programmed in the factory prior
to shipping. Therefore, a
CW-5HD shipped to one region
can not be used in a different
region.
（２）Outdoor usage of the 5GHz
frequency band, which the CW-5HD uses, is controlled by region. This table shows the
approved frequencies and the corresponding channels of CW-5HD in the EU region.
（３）The maximum transmission distance varies depending on the surroundings, radio wave
conditions, buildings structural composition etc. Although the indoor transmission
distance is indicated as 30m (with CH1, POWER MODE=HIGH), however this is not a
guaranteed operational level.
（４）When the CW-5HD TX and RX are located close to each other, the received signal may be
too strong and may disturb the video. When the CW-5HD TX and RX are used close to
each other (say 3m or less as an example), set the POWER MODE switch of CW-5HD TX
in LOW mode.
（５）CW-5HD can not be equipped with external antennas.
（６）The V-Plate connecting CW-5HD to video cameras, monitors, etc. does not have Digi-View
series II capability for an ENDURA series battery. Therefore, CW-5HD can not support
the battery’s digital communication between an ENDURA battery and video camera.
（７）The SDI output of CW-5HD conforms to SMPTE-292M/SMPTE-259M. However, in some
linked conditions, clock jitter of SDI signals may exceed the regulated values.
（８）CW-5HD uses SDI embedded audio, however only Audio channels 1 and 2 can be
transmitted.
（９）It should be understood that the quality level of video transmitted by wireless signal is not
as good as that by hard-wired cable signals.
