Operation & Interface Functions
Indicator Lights
- POWER LED: Blue LED illuminates when the device is powered on
- IN LED: Blue LED illuminates when the HDMI IN port is connected to an active source device
- OUT LED: Blue LEDs illuminate when the corresponding HDMI OUT ports are connected to active display devices
EDID Configuration (Dip Switch)
- COPY Mode: The unit reads the EDID setting of HDMI OUT 1 display device and sends it to the source device (priority order: OUT 1 → OUT 8). If no EDID is detected from OUT 1, it reads from OUT 2, and so on.
- AUTO Mode: The unit compares EDID settings of all HDMI OUT 1~8 display devices, sends the best-matched EDID to the source device, ensuring compatible signal output to all displays.
Interface Connections
- HDMI IN: Connect to HDMI source devices (Blu-ray player, DVD player, set-top box, PS3/PS4, etc.) via HDMI cable
- HDMI OUT 1~8: Connect to HDMI display devices (TV, monitor, audio amplifier, etc.) via HDMI cable
- SERVICE Port: Micro USB port for firmware update only
- DC 12V Port: Connect to the provided 12V/1A power adapter for power supply
