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
DFS1 function 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.
