CW-7 Important Notification of Use
CAUTION
IDX requires that CW-7 TX (transmitter) be installed on the
V-Mount interface of a video camera. Depending on
connectivity, installing CW-7 TX with equipment other than
a video camera may cause problems to CW-7 TX or other
equipment.
For further information, and to install the CW-7 system with
equipment other than a video camera, please contact your
local IDX representative.
Caution on the use of this product and radio waves
This product has been approved for technical standard compliance
certification as a wireless device of radio stations with low antenna
power specified under the FCC Radio wave regulation. Thereby a
license for radio station use is not required to operate this product.
This product is allowed to be used only in US.
This product is pursuant to the FCC regulations and can be used in
both indoor and outdoor environments.
When the frequency selection SW is "DFS AUTO" mode, it will take
about one minute to link the system in order to detect the presence or
absence of radar wave in the area.
CW-7 uses 5GHz band radio frequencies and it has been shown not to
interfere with medical devices. However, when in use, it is
recommended to keep the CW-7 at least 30cm (12in.) away from
medical devices to ensure safety.

II.CONTENTS
1. Product overview
The CW-7 is a wireless transmission device which transmits HD-SDI/SDI
video and audio with 5GHz band radio frequencies. TX is the transmitter,
and connects to a video source such as a video camera. RX is the receiver,
and connects to a monitor, for example. Video and audio from the video
source can be observed without cable connections. CW-7, also, provide
DFS1function which enable to use indoor and outdoor without any
concern of local wireless regulations. With the transmission output power
in HIGH mode, the signals can be transmitted up to 50m (150ft) if a direct
line-of-sight is offered between TX and RX.
Features
Supported HD-SDI / SD-SDI input and output.
Transmitting HD video (1080i, 1080p, 720p) and SD video (525i/625i)
Supporting SDI embedded audio. (Audio CH1 and CH2 only)
Transmission delay is less than 1msec.
Signal protection by 128bit AES encryption (in UNICAST mode)
WHDI technology supplied by AMIMON enables un-compressed high
quality video transmission.
Both automatic and manual selection of transmitted frequencies.
Newly adopted DFS functionality allows for use in outdoors as well.
Two-level select (HIGH/LOW) of transmission output power.
Power can be supplied either by V-Mount type Lithium Ion battery or by
EXT DC, via XLR 4P connector.
Backup power failure function enables switching to a battery if the
external DC failed.
Either of EXT DC or battery power supply to the camera thorough CW-7.
1DFS (Dynamic Frequency Selection):
This function automatically changes the frequency used by the wireless
equipment. The provided 5GHz band wireless equipment will not affect the
weather radar.

Attention
＊The transmission distance may vary depending on frequencies,
surroundings, radio wave conditions, buildings, weather condition etc.
The transmission distance of 50m (150ft) is not definite.
＊When CW-7 is placed near a device such a TV, the transmitted video
image may be disrupted. Please increase distance between TV and
CW-7 when this happens.
＊In locations where other 5GHz wireless devices are operating, CW-7
may be affected by other devices causing disconnection and/or
interruption of video.
＊Signal reception may vary depending on height and angle of CW-7
placement. If reception is not stable then manually relocate to optimize
the signal.

3.2. CW-7 Link initialization
When the power switch is turned on, TX and RX will start searching for a
frequency that it can be linked to. It will change the link mode if it is in
operation or the transmission signal is lost. The three LED lights will cycle
ON and OFF, starting from bottom to top until it is firmly linked. The LED
lights switching is an indication that it is searching for a counter device.
Searching (TX): Green LED blinks repeatedly.
Searching (RX): Green LED blinks repeatedly.

4. Selecting frequencies and power output
FREQ SELECT switch is equipped on both TX and RX. POWER MODE
switch is located on TX side only.
FREQ SELECT switch is used to select transmission and receiving
frequency.
FREQ SELECT switch must be same position on both TX and RX.
POWER MODE switch enables you to change the transmission power,
HIGH or LOW.

There is a strict regulation allowing certain frequencies for indoor use only.
Please note that uses of unauthorized frequencies outdoors may be a
violation of the law.

4.2. DFS function
When the FREQ SELECT switch selects DFS AUTO, DFS (Dynamic
Frequency Selection) function will be enabled. If DFS detects radio waves
of weather radar (using 5GHz band) the system will automatically search
other available frequency band to avoid interference.
The DFS function is regulated by the radio standard to use the frequencies
of 5250-5300MHz and 5470-5725MHz.
Important Notes
＊When DFS AUTO is selected, waiting time of the link will be one minute
or more due to initialization.
＊The waiting time (one minute) occurs in the following cases:
1.Power turned ON and FREQ SELECT switch is set to DFS AUTO.
2.FREQ SELECT switch changed to DFS AUTO position during
operation.
＊While the system is initializing, the RED and GREEN LINK LED will
switch back and forth from bottom to top repeatedly.
→Refer P. 14 “CW-7 Link initialization”
＊In the event of conflict with radar wave, DFS automatically enables to
connect to another available frequency without interrupting the video.
＊MULTICAST with DFS AUTO will not function simultaneously and
Amber LED blinks as “LINK MODE ERROR”.
→Refer P. 13 “LED indicator functions”

17
5. Link mode -UNICAST/MULTICAST
UNI/MULTI switch is used to select the link mode. UNI/MULTI select
switch is located on both TX and RX and must be set in the same mode.
5.1. UNICAST mode (1 to 1 communication)
When UNI/MULTI switch is set to UNI position, CW-7 links in UNICAST
mode. In UNICAST mode, the system communicates only between the TX
and RX with the same serial numbers. The transmission signal is encoded
by 128bit AES encryption therefore it will not be intercepted by other CW-7
nearby.
The pair with the same serial number
2nd RX unit is not usable
UNICAST operation

18
5.2. MULTICAST mode (1 to n communication)
When UNI/MULTI switch is set to MULTI position, the CW-7 links in
MULTICAST mode. In MULTICAST mode, the transmitted video and
audio can be received by multiple RX. Please note that if MULTICAST
mode had been selected, there is no AES encryption.
There is no limit on the number of receiving CW-7 RX in MULTICAST
mode as long as they are within reach of the transmitted signal and
existing environmental conditions are taken into regard.
Important Notice
＊MULTICAST function denied when DFS AUTO is selected.
When the FREQ SELECT switch selected at DFS AUTO, the link LED
display as “Link mode error”.
→P. 13 “LED indicator functions”
＊CH1 to CH4 (non-DFS band) are limited to use for MULTICAST
operation.
