3. Quick Start Guide

Follow these steps to get your C6 encoder up and running immediately.

Power On Connect the 12V DC power adapter to the rear port and secure the locking ring. Press the power switch.

If using a PoE (Power over Ethernet) switch, the power adapter is not required.
Connect Video Sources Connect your camera or video switcher to the HDMI IN or SDI IN port.
- Optional: Connect a local monitor to the corresponding Loop Out port for zero-latency monitoring.
Network Connection Connect an Ethernet cable from the C6 to your network switch or router.
- The device is set to DHCP by default and will automatically acquire an IP address.
Connect Audio (Optional) Connect an external microphone (3.5mm) or audio mixer output to the MIC port if you are not using embedded HDMI/SDI audio.
Verify Status Wait for the LCD screen to light up. It will display the CPU status and the acquired IP address (e.g., 192.168.1.100).

4. LCD Screen Operation

The C6 features a 2.0-inch built-in LCD screen combined with physical navigation buttons. This interface is designed for PC-Free operation, allowing you to monitor signal integrity, manage network connections, and control recording/streaming status directly from the device.

The physical buttons located to the right of the screen are your primary control tools:

UP / DOWN: Cycle through the main dashboard pages (System State -> Signal Source -> Network -> Encoding -> Stream -> Recording).
OK (Square Button):
- Short Press: Enter a sub-menu or confirm a selection (e.g., toggle a switch).
- Long Press: Triggers specific shortcuts (e.g., Factory Reset on startup).

4.2 Preview Mode (Default Status)

Upon startup, if no operation is performed for 30 seconds, the screen automatically enters Real-time Preview Mode. This is critical for confirming signal integrity without a monitor.

Signal Logic:
- Default: Displays the HDMI input source.
- Priority in Mix Mode: If “Mix A” is selected, HDMI is the main background. If “Mix B” is selected, SDI is the main background.
- Failover Display: If the primary source is lost, the screen will attempt to display the secondary source or show a blue screen with messages like “No Signal”.

4.3 System Status Dashboard

This is the root menu page, providing a comprehensive health check of the device.

Performance Monitoring:

CPU & Memory%: High usage (above 90%) may indicate the device is overloaded (e.g., too many concurrent high-bitrate streams).

Device Identity

Serial No. & Firmware Version: Essential information for technical support cases.

Device Name: Matches the NDI source name visible on the network.

Pressing OK on the System Status page enters the critical maintenance menu:

Reset: Restores factory settings. Use this if you are locked out of the device or facing configuration conflicts.

Reboot: Performs a safe soft restart of the system.

Update (via USB): Allows firmware upgrades without a network connection. * Requirement: Insert a USB drive with the firmware (.bin file) in the root directory before selecting this option. :::tip[Hardware Shortcut] If the menu is inaccessible, press and hold both the Up and Down buttons on the front panel simultaneously for 8 seconds. The device will automatically reset and reboot.

4.5 Local Recording

Manage recording to the local SD card or USB drive.

Storage Monitor: Displays used space vs. total capacity (e.g., 10G/64G).

Action: Press OK to instantly Start/Stop Recording. The timer will appear to confirm recording is active.

4.6 Signal Source Details

Resolution: Same As The Video Source is recommended for 1:1 pixel fidelity. Select lower resolutions (e.g., 1280x720) only to save bandwidth on unstable networks.
Type (Codec):
- H.264 (AVC): Max compatibility (Old players, RTMP to YouTube/Facebook).
- H.265 (HEVC): High efficiency. Delivers equal quality at 50% lower bitrate, ideal for bandwidth-constrained environments.
Rate Control:
- CBR: Best for Live Streaming. Ensures steady data flow to prevent network spikes.
- VBR: Best for Local Recording. Allocates data dynamically to save storage space.
Bitrate: Controls data usage (Higher = Better Quality).
- Standard: 4Mbps - 10Mbps (for 1080p60).
- Max: Up to 40Mbps for visually lossless needs.
Framerate: Set to match your camera input (e.g., 60fps) for smooth motion.
GOP: Defines Keyframe interval.
- Standard: Set to 2x Framerate (e.g., 60 for 30fps) for a 1-second interval.
- Low Latency: Lower values reduce latency but increase bandwidth usage.
NDI Options: _ NDI|HX2: Balanced efficiency with full manual control over Bitrate and GOP. _ NDI|HX3: Ultra-Low Latency & High Quality.

When NDI|HX3 is selected, Bitrate, Rate Control, and GOP settings will be disabled. The system automatically manages these parameters to strictly ensure low-latency standards.

5.3.4 MJPEG Configuration

This configuration directly controls the image refresh rate for the device’s physical LCD Screen and the remote preview thumbnail on the CNDLive Manager platform. The MJPEG stream generates a sequence of snapshots for low-bandwidth monitoring without consuming your primary video encoding resources.

mjpeg * Resolution: Currently fixed at 640x360. This specific resolution is locked to ensure maximum system stability and prevents management traffic from interfering with your main video broadcast. * JPEG Capture Interval: Determines how frequently a snapshot frame is refreshed. A shorter interval provides a smoother preview but uses slightly more system resources. * Selection: Choose from standard presets (1s, 2s, 3s) via the dropdown menu. * Custom: Select “Custom” to input a specific integer. Note that the value must be less than 10s.

5.3.5 Audio Source Selection

Configure audio input sources, volume levels, and encoding formats. This section also supports audio mixing and lip-sync adjustment.
