300meters Transmission
3G/HD-SDI non-compressed, ≤1ms latency
In Line-of-Sight, CW-S300 supports non-compressed 3G/HD-SDI 300 meters (1000 feet) transmission, with less than 1 millisecond latency.
Embedded Audio/Timecode Transmission
CW-S300 supports SDI embedded audio (CH1&2) transmission, and supports SDI timecode transmission.
5.1-5.9GHz Frequency
DFS comply
CW-S300 wireless system works at 5.1-5.9GHz License-free frequency, and support DFS (Dynamic Frequency Switch). The transmitter and receiver are paired to work. Support 3-4 pairs wireless channels to work together in one location.
The wireless output power is less than 100mW, which will not do harm to human bodies.
Multicast Setting
Users can Pair up to 4 Receivers with 1 Transmitter, to enable 1 Transmitter to multi Receivers multicast mode.

Supported Video Formats
CW-S300 supports the following video formats to transmit:
Transmitter Input | Supported formats |
SDI |
1080p (60 / 59.94 / 50 / 30 / 29.97 / 25 / 24 / 23.98) |
1080psf (30 / 29.97 / 25 / 24 / 23.98) | |
1080i (60 / 59.94 / 50) | |
720p (60 / 59.94 / 50) |
The receiver outputs the same format as transmitter inputs.
Pair the Transmitter and Receiver
The CW-S300 wireless transmitter and receiver are already paired in factory. You can directly use without re-pair.
But if you have several units and mixed up the transmitters and receivers, or if you need to do multi-cast, you need to re-pair by yourself. Pairing steps:
(1) CW-S300 Transmitter powered on, and SDI in connected with camera or video source device.
(2) CW-S300 Receiver powered on, and SDI out connected with a monitor. The monitor will display “Searching for Camera Unit” then.
(3) Press and hold the Pair button on Receiver, till the monitor displays “Please Press Registration Button on Camera Unit”, release the Receiver Pair button.
(4) Press and hold the Pair button on Transmitter, till the monitor displays “Registration in Progress”, release the Transmitter Pair button.
(5) When progress bar finished, the Transmitter and Receiver are paired successfully.
How to Get the Best Effect of Wireless Transmission
(1) Set the Transmitter and Receiver antennas straight up, even if they are laid down installed.
(2) Set the Receiver as high as possible.
(3) Avoid walls, trees, water and any blockage as best as you can.
