User Manual for SWIT CREW-V Wireless Video Transmission System

Quick guide from the manual

The SWIT CREW-V is a wireless video transmission system supporting SDI and HDMI. It features auto-pairing, 128-bit encryption, and UVC support for direct streaming to computers. For optimal performance, ensure antennas are vertical and the receiver is positioned as high as possible. The system supports up to 1080p 50/60Hz transmission.

Device Overview

The system consists of a transmitter and receiver. Key interfaces include:

• Antenna: High-gain antennas for wireless transmission.
• LCD Display: Shows signal format, channel, quality mode, and fan status.
• Five-direction switch: Used to navigate the menu (up, down, left, right, vertical press to confirm).
• Power: Supports 7V-17V DC input via LEMO 0B 302 connectors or battery plates (compatible with Sony L-series NP-F770/970).
• USB-C: Used for system upgrades and UVC output.

Pairing Procedure

1. Power on both the transmitter and receiver.
2. On the transmitter, toggle the five-direction switch to the right to access the PAIR menu.
3. Select START and press the switch vertically to confirm. The transmitter will prompt "Ready to pair?".
4. On the receiver, navigate to the PAIR menu and confirm.
5. Wait for the pairing process to complete. The transmitter will display the number of connected receivers, and the receiver will show a success message.

Connection and Setup

Connect the SDI/HDMI output from your camera to the transmitter's input. Connect the receiver's SDI/HDMI output to your monitor or switcher. The system automatically detects the video interface, prioritizing SDI if both are connected. Ensure all devices are powered on and antennas are straight.

UVC Streaming

The receiver can output video directly to a computer via USB-C for streaming applications like OBS:

• Connect the receiver to the computer using a USB-C cable.
• Open Device Manager on your computer to confirm the device is recognized as a UVC Camera.
• In OBS, add a new source, select Video Capture Device, and choose the UVC Camera from the device list.

System Upgrade

To update firmware, download the package to the root directory of a USB flash drive. Connect the drive to the transmitter or receiver via an OTG adapter. Navigate to the VER menu, select START, and follow the on-screen prompts. Restart the device after the upgrade is complete.

Troubleshooting

If you experience issues, check the following:

• No display: Verify power connections, ensure antennas are tightened, check video cable integrity, and confirm the camera's output format is supported.
• Poor video quality: Ensure the transmitter and receiver are within range, minimize environmental interference (walls, trees, water), and reboot the devices if necessary.
