Setup
Follow these steps to set up your Novastar MCTRL300 unit.
- Power Connection: Connect the provided power cable to the AC input port on the rear of the MCTRL300 and then to a suitable power outlet (AC 100-240V~50/60Hz). Ensure the power switch is in the OFF position before connecting.
- Video Input: Connect your video source (e.g., computer, media player) to the DVI input port on the MCTRL300 using a DVI cable.
- Audio Input: If audio transmission is required, connect your audio source to the audio input port.
- Ethernet Output to LED Display: Connect the dual Ethernet outputs (OUT1, OUT2) to your LED display receiving cards using standard Ethernet cables. The MCTRL300 supports hot backup between these ports.
- USB Connection to PC: Connect the type-B USB control port on the MCTRL300 to your computer using a USB cable. This connection is necessary for configuring and controlling the display via NovaStar software.
- Light Sensor (Optional): Connect a compatible light sensor to the dedicated light sensor interface if automatic brightness adjustment is desired.
- Cascading (Optional): For controlling multiple MCTRL300 units, use the UART IN and UART OUT ports to cascade devices.
