to release (switch between upper and lower layers, after the switch is complete, press K1 briefly to start fusion)
3、Indicator Lights
DC:
Monitor link indicator. If it is not on, indicating that the fusion device and monitor are not connected. Check the interface and cables, and if necessary, turn off the monitor and restart it.
RH:
Upper-layer (secondary PC) on/off indicator. ON= When the light is on, it turns on the normal fusion overlay. OFF= when the light is off, it turns off the upper screen
RX1:
Upper-layer (secondary PC) indicator,The light is not on, indicating that the fuser and the secondary unit are not connected. Check the interfaces and wires on both sides, and restart the secondary unit if necessary

4、On-Screen Parameter Info ( Short-press K1)
MAIN:
Resolution and refresh rate of the lower-layer RX0 (Host PC).
SECOND:
Resolution and refresh rate of the upper-layer RX1 (secondary PC).
ALPHA:
Chroma-key strength. 0 = off; 5–255 = strength.
BD:
Firmware date.
UID:
Unique device chip ID.
EDID:
Identification Mode: A or B (default A).
Long-press K1 for about five seconds to toggle. If Mode A fails to light the display, switch to Mode B. Switching will auto-restart the fuser.
A = ultra-universal; B = native-compatibility.
