Edid copy command package length is 13byte:
[0xa5+0x5b+0x03+0x04+
output port (1~4)
+0x00+
input port(1~4)
+0x00+0x00+0x00+0x00+0x00+
checksum
]
Means: copy output port X edid to input port X
[0xa5+0x5b+0x03+0x03+
output port (1~4)
+0x00+0x00+0x00+0x00+0x00+0x00+0x00+
checksum
]
Means: copy output port X edid to all input port
Output HDP status query package is 13byte:
This is a query command which mean you must send query package and then receive an answer.
For example: Query output 1(1~4) HPD status
Send package:
A5 5B 01 05
01
00 00 00 00 00 00 00 F9
Receive package: A5 5B 01 05 01 00
FF
00 00 00 00 00 FA
The red
01
mean the output port number, it should be 1~4.
The blue
FF
mean this port’s HPD is LOW, if
00
mean HIGH.
Input port status query package is 13byte:
This is a query command which mean you must send query package and then receive an answer.
For example: Query input 1(1~4) status
