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

HDMI Cable Length Recommendations

  • 4K2K@60Hz / 8-bit YUV 4:4:4: Maximum 3m
  • 4K2K@30Hz / 8-bit: Maximum 10m
  • 1080p@60Hz / 8-bit: Maximum 15m

Applicable Scenarios

  • Home Entertainment: Home theater, entertainment rooms, synchronous display of high-definition content on multiple TVs/monitors
  • Commercial Display: Shopping malls, airports, hotels, digital signage and advertising screen synchronous content release
  • Educational Institutions: Classrooms, lecture halls, synchronous display of teaching content on multiple screens for better viewing
