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).
