Input Switching
The following command switches input sources.
Byte 1 Byte 2 Byte 3 | Byte 4 | Byte 5(optional) |
(Header) (Address) (Video Input) (Audio Input) RGB Delay (see note)
E8 | 00 to FF 00 to 0A | 0 to OA | 01 to FF |
The Audio Inputs can be switched independently from the Video.
Bytes 3 and 4
01 to 04 correspond to PC inputs 1 to 4
05 to 0A correspond to video inputs 1 to 6 00 for Blank
1F no change
Byte 5
This switches the input sync but holds the RGB in blank for the time period set by the byte. This allows for a clean switch between inputs.
The value is in seconds (e.g. 03 = 3 seconds).
If RGB delay is not required then ignore the 5th byte.
Master Volume (Changes all Input Levels)
The overall Volume level increases 0.5db each time the following command is sent:
Byte 1 Byte 2 Byte 3
(Header) (Address) (Increase)
E8 | 00 to FF 10 |
The overall Volume level decreases 0.5db each time the following command is sent:
Byte 1 Byte 2 Byte 3
(Header) (Address) (Decrease)
E8 | 00 to FF 20 |
Absolute Volume Level
A Volume value can be set directly using the following command:
Byte 1 | Byte 2 | Byte 3 | Byte 4 |
(Header) | (Address) |
| (Volume Value) |
E8 | 00 to FF | 0F | 00 to 5A |
with 00 as the loudest (0dB)
