I. SAFETY INSTRUCTIONS To use this product safely and correctly please follow the safety precautions set out below. Product misuse may cause fire, shock, injury, product failure or other hazards. Please read this manual prior to using your CW-7 and retain for future reference. CAUTION Fire or electric shock may cause injury or other accidents.
CAUTION - continued Fire or excessive heat may cause injury or damage to surroundings. ●If ventilation openings are blocked, this may cause excessive heat or damage. ●After long periods of continuous use, the case of the unit may become very heated – be cautious when touching. ●Using the CW-7 in an environment with a lot of moisture, soot or dust may cause excessive heat or electric shock. ●Do not stare at LED lights on the side panel of CW-7, as this may cause damage to the eyes.
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.
CW-7 Important Notification of Use CAUTION Please do not connect between DC-IN of CW-7 and DC-OUT of the camera while powering with battery as shown below. This may cause serious damages to the CW-7. Attention: When used EXT-DC and battery simultaneously Mount a battery after EXT-DC power is turned ON. When EXT-DC power OFF and turns ON again, please remove battery.
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 DFS 1 function which enable to use indoor and outdoor without any concern of local wireless regulations.
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.

3. LED indicators 3.1. LED indicator functions TX RX MODE STATUS LED Indicates manually selected transmission output power mode (HIGH/LOW), and the UNICAST/MULTICAST setting. HIGH : Two lights on. LOW : One light on. UNICAST : LED lights Green. MULTICAST : LED lights Amber. LINK LED Indicates the link status. Initializing/Mode changing : Red light on. Linked (no video signal) : Amber light on. Linked (with video signal) : Green light on. Link mode error : Amber blinking.
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. 4.1. Available frequencies and transmission power The table shows the available frequencies and transmission power for U.S. region.
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.
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.
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. MULTICAST operation 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.
6. Operation guide 6.1. Set up The CW-7 does not include various accessories that may be used in its operation. Please obtain each of the following items as needed for your specific application before use. BNC cable for HD-SDI IN and OUT. IDX ENDURA batteries or external power supply Note: Power supply; Use only an AC adaptor or batteries specified below. CW-7 accepts the DC power range of 11V – 17V. EXT DC-IN connector is XLR-4P male, Pin No.1: negative (-), Pin No.4: positive (+).
6.3. When signal reception is unstable Unstable signal reception may be caused by the placement, such as position, height and angle of TX and RX or the operating environment. When TX and RX are placed too close to each other, the transmission signal may become too strong and may disturb the video signal. Please set the POWER MODE switch on the TX to LOW position when the distance between TX and RX is 3m or less. 6.4.
7. Important notice 1. 2. 3. 4. 5. 6. 7. 8. 9. The available service frequencies and transmission power varies depending on the designated regions because each region has different local regulations and restrictions of radio waves. Therefore all the CW-7s are programmed accordingly to each region, thus, shipment and usage of the CW-7 in an unspecified region may cause violation of law. Use of 5GHz band outdoors has been limited by the frequency. CH3, CH4 and DFS AUTO position allows to outdoor use.
